The Internet of Things IntelliSense recognition technology and pervasive computing, ubiquitous network integration application,known as the third wave of the world’s information industry development following the computer,the Internet. Not so much the Internet of Things is a network, as Internet of Things services and applications,Internet of Things is also seen as Internet application development. Therefore,the application of innovation is the core of the development of Internet of Things,and 2.0 of the user experience as the core innovation is the soul of Things.2.The meaning of ’’material”Where the ’’objects” to meet the following conditions can be included in the scope of the "Internet of Things":1.Receiver have the appropriate information;2.Have a data transmission path;3.Have a certain storage capabilities;4.To have the CPU;5.To have the operating system;6.Have specialized applications;7.Have a data transmitter;8.Follow the communication protocol of Things;9.World Network,a unique number that can be identified.3."Chinese style" as defined inInternet of Things (Internet of Things) refers to is the ubiquitous (Ubiquitous) terminal equipment (Devices) and facilities (Facilities), including with the "inner intelligence" sensors,mobile terminals, industrial systems,floor control system,the family of Intelligentfacilities,video surveillance systems,and external can "(Enabled),such as RFID,a variety of assets (the Assets),personal and vehicle carrying the wireless terminal” intelligent objects or animals n or” smart dust ’’(the Mote),through a variety of wireless and/or cable over long distances and/or short-range communication networks to achieve interoperability (M2M),application integration (the Grand Integration),and based on cloud computing,SaaS operation mode,in internal network (intranet),private network (extranet), and / or the Internet (Internet) environment, the use of appropriate information security mechanisms to provide a safe,controlled and even personalized real-time online monitoring,retrospective positioning,alarm linkage, command and control plan management, remote control,security,remote repair and maintenance, online upgrades,statistical reporting, decision support,the leadership of the desktop (showcase of the Cockpit Dashboard) management and service functions,’’Everything,” ’’efficient,energy saving, security environmental protection/"’ possession,control,Camp integration [1].4.EU definitionIn September 2009,the Internet of Things and enterprise environments held in Beijing,China-EU Seminar on the European Commission and Social Media Division RFID Division is responsible for Dr. Lorent Ferderix,given the EU’s definition of things: the Internet of Things is a dynamic global network infrastructure, it has a standards-based and interoperable communication protocols, self-organizing capabilities, including physical and virtual "objects” of identity, physical attributes,virtual features and smart interface and seamless integration of information networks . Internet of Things Internet and media,the Internet and business Internet one,constitute the future of the Internet.5.changeThe Internet of Things (Internet of Things) the word universally recognized at home and abroad Ashton, Professor of the MIT Auto-ID Center in 1999 first proposed to study RFID. The report of thesame name released in 2005, the International Telecommunication Union (ITU), the definition and scope of the Internet of Things has been a change in the coverage of a larger expansion, no longer refers only to the Internet of Things based on RFID technology.Since August 2009, Premier Wen Jiabao put forward the "Experience China” Internet of Things was officially listed as a national one of the five emerging strategic industries,to write the •’Government Work Report’1 Internet of Things in China has been the great concern of the society as a whole degree of concern is unparalleled in the United States,European Union, as well as other countries.The concept of Internet of Things is not so much a foreign concept, as it has been the concept of a "Made in China' his coverage of the times,has gone beyond the scope of the 1999 Ashton professor and the 2005 ITU report referred to, Internet of Things has been labeled a "Chinese style" label.6.BackgroundThe concept of Internet of Things in 1999. Internet-based, RFID technology and EPC standards,on the basis of the computer Internet,the use of radio frequency identification technology, wireless data communication technology, a global items of information to real-time sharing of the physical Internet ’’Internet of things” (referred to as the Internet of Things),which is also the basis of the first round of the China Internet of Things boom set off in 2003.The sensor network is built up based on sensing technology network. Chinese Academy of Sciences in 1999 on the start sensor network research and has made some achievements in scientific research,the establishment of applicable sensor network. 1999, held in the United States,mobile computing and networking International Conference, "The sensor network is a development opportunity facing humanity in the next century. In 2003, the United States,"Technology Review” propo sed sensor network technology will be future changes ten people’s lives first.November 17, 2005, the WSIS held in Tunis (WSIS),the International Telecommunication Union released ITU Internet Report 2005: Internet of Things ”,citing the concept of the” Int ernet of things "• The report pointed out that the ubiquitous ’’Internet of Things" communication era is approaching, all the objects in the world, from tires to toothbrushes, from housing to the tissue via the Internet, take the initiative to be exchanged. Radio Frequency Identification (RFID),sensortechnology, nanotechnology,intelligent embedded technology will be more widely used.According to the description of the ITU, the era of things,a short-range mobile transceivers embedded in a variety of daily necessities,human beings in the world of information and communication will receive a new communication dimension, from any time communication between people of the place of connection extended to the communication connection between persons and things and things and things. The Internet of Things concept of the rise,largely due to the International Telecommunication Union (ITU), the title of Internet of Things 2005 annual Internet Report. However,the ITU report the lack of a clear definition of Things.Domestic Internet of Things is also there is no single standard definition, but the Internet of Things In essence,the Internet of Things is a polymer application of modern information technology to a certain stage of development and technological upgrading of various sensing technology modern network technology and artificial intelligence and automation technology aggregation and integration of applications,so that the human and material wisdom of dialogue to create a world of wisdom. Because the development of the Internet of Things technology,involving almost all aspects of IT,innovative application and development of a polymer, systematic, and therefore be called revolutionary innovation of information industry. Summed up the nature of the Internet of Things is mainly reflected in three aspects: First, the Internet features that need to be networked objects must be able to achieve the interoperability of the Internet; identification and communication features,that is included in the Internet of Things "objects" must to have the functions of automatic identification and physical objects communication (M2M); intelligent features,the network system should have automated,self-feedback and intelligent control featuresJanuary 28, 2009, Obama became the President of the United States,held with U.S. business leaders a "round table’’,as one of the only two representatives,IBM CEO Sam Palmisano for the first time that H the wisdom of the Earth” this concept, it is recommended that the new government to invest in a new generation of intelligent infrastructure.February 24,2009 news,IBM Greater China CEO money crowd called "Smarter Planet” strategy announced in the forum 2009IBM.This concept was put forth, that is the great concern of the United States from all walks of life,and even analysts believe that IBM’s vision is very likely to rise to U.S. national strategy,and caused a sensation in the world. IBM believes that the industry, the next phase of the mission is to make full use of the new generation of IT technology in all walks of life among specifically,is the embedded sensors and equipment to the power grid,railways,bridges,tunnels, highways, buildings, water supply systems dams,oil and gas pipelines and other objects,and is generally connected to the formation of Things.Strategy conference, IBM, and implant the concept of ’’wisdom” in the implementation of the infrastructure,strong,not only in the short term to stimulate the economy,promote employment,and in a short period of time for China to build a mature wisdom infrastructure platform.IBM n Smarter Planet” strategy will set off again after the wave of Internet technology industrial revolution. Former IBM CEO Lou Gerstner has raised an important point of view, every 15 years,a revolution in computing model. This judgment is the same as Moore’s Law accurately call it a n15-year cycle Law' Before and after 1965, changes to the mainframe as a symbol,1980 marked by the popularization of personal computers,1995, the Internet revolution. Each such technological change are caused by the enterprise, industry and even the national competitive landscape of major upheaval and change. To a certain extent in the Internet revolution is ripening by the ”information superhighway” strategy. 1990s,the Clinton administration plan for 20 years, $ 200 billion to -4000 billion,construction of the U.S. National Information Infrastructure,to create a huge economic and social benefits.Today, the H Smarter Planet" strategy by many Americans that there are many similarities with the "informa tion superhighway”,the same they revive the economy,a key strategy for competitive advantage. The strategy can be set off, not only for the United States, such as the Internet revolution was the wave of technological and economic concern, more attention from the world.H Internet of Things prospects are very bright,it will dramatically change our current way of life.’’ Demonstration director of the Center of Nanjing University of Aeronautics and Astronautics,National Electrical and Electronic Zhao Guoan said. Industry experts said that the Internet of things to our life personification of the things became a kind of human.Goods (goods) in the world of physicalobjects associated with each other "exchange' without the need for human intervention. The Internet of Things using radio frequency identification (RFID) technology, to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet. It can be said that the Internet of Things depict the world is full of intelligent. In the world of Internet of Things, material objects connected to the dragnet.The second session,held at Peking University in November 2008, China Mobile Government Seminar H Knowledge Society and Innovation 2.0n,the experts made the mobile technology, the Internet of Things technology led to the development of economic and social form, innovative forms of change,and promote the The next generation of innovation for the knowledge society as the core of user experience (innovative 2.0) the formation of innovation and development of the form to pay more attention to the user to focus on people-oriented. Research institutions is expected to 10 years,the Internet of Things may be mass adoption of this technology will develop into one of thousands of yuan-scale high-tech market,the industry than the Internet 30 times.It is learned that the things industry chain can be broken down into the identity,perception,processing and information transfer,four links, each link of the key technologies for the wireless transmission network of RFID, sensors,smart chip and telecom operators. EPOSS in the ’’Internet of Things in 2020” report,an analysis predicted that the future development of the Internet of Things will go through four stages, 2010, RFID is widely used in the field of logistics,retail and pharmaceutical objects interconnect 2010 to 2015,2015 〜In 2020,the object into the semi-intelligent, intelligent objects into 2020.As the vanguard of the Internet of Things,RFID has become the most concerned about the technology market. The data show that the global RFID market size in 2008 from $ 4.93 billion in 2007 rose to $ 5.29 billion,this figure covers all aspects of the RFID market,including tags, readers and other infrastructure, software and services. RFID card and card-related infrastructure will account for 57.3 percent of the market, reaching $ 3.03 billion. Application from financial and security industries will drive the market growth of RFID cards. Analysys International forecasts,the Chinese RFID market size in 2009 will reach 5.0 billion, a CAGR of 33%, in which the electronic tag is morethan 3.8 billion yuan,the reader close to 700 million yuan, software and services market to reach 500 million yuan pattern.MEMS is the abbreviation of the micro-electromechanical systems,MEMS technology is built on the basis of micro / nano, the market prospect is broad. The main advantage of the MEMS sensor is the small size,large-scale mass production cost reduction,mainly used in two major areas of automotive and consumer electronics. Under ICInsight the latest report is expected in 2007-2012, global sales of semiconductor sensors and actuators based on MEMS will reach 19 percent compound annual growth rate (CAGR), compared with $ 4.1 billion in 2007 to five years will achieve $ 9.7 billion in annual sales.7.PrincipleInternet of Things is on the basis of the computer Internet, RFID, wireless data communications technology, to construct a cover everything in the world’s ’’Internet of Things' In this network, the goods (products) to each other ’’exchange”,without the need for human intervention. Its essence is the use of radio frequency identification (RFID) technology to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet.The Internet of Things is a very important technology is radio frequency identification (RFID) technology. RFID is radio frequency identification (Radio Frequency Identification) technology abbreviation,is an automatic identification technology in the 1990s began to rise,the more advanced a non-contact identification technology. The development of RFID technology based on a simple RFID system, combined with existing network technology, database technology, middleware technology, to build a one composed by a large number of networked readers and numerous mobile label, much larger than the Internet of Things trend.RFID,It is able to let items "speak” a technique. In the "Internet of Things” con cept,RFID tags are stored in the specification and interoperability information collected automatically by wireless data communications network to a central information system,to achieve the identification of goods (products), and then through the open computer network for information exchange and sharing, items "transparent” management.The information technology revolution in the Internet of Things is referred to as IT mobile Pan of a specific application. Internet of Things through IntelliSense,identification technology andpervasive computing, ubiquitous network convergence applications,breaking the conventional thinking before,human beings can achieve ubiquitous computing and network connectivity [3]. The traditional thinking has been the separation of physical infrastructure and IT infrastructure: on the one hand,airports,roads,buildings,while on the other hand,the data center,PC,broadband. In the era of the ’’Internet of Things’’,reinforced concrete,cable with the chip,broadband integration into a unified infrastructure, in this sense, the infrastructure is more like a new site of the Earth, the world really works it, which including economic management, production operation, social and even personal life. H Internet of Things” makes it much more refined and dynamic management of production and life, to manage the future of the city to achieve the status of "wisdom” to improve resource utilization and productivity levels,and improve the relationship between man and nature.8.Agency1,institution-buildingAs the first national Internet of Things industry community organizations - the application of professional Committee of China Electronic Chamber of Things technology products (referred to as: ’’objects of the IPCC n),the Ministry of Civil Affairs in June 2010,preliminary approved by the Ministry of August being reported that the Ministry of Civil Affairs for final approval.2, the main taskServe as a bridge between business and government to assist the Government of the industry guidance,coordination,consultation and services to help members to reflect the business requirements to the Government; coordinate the relationship between enterprises to strengthen technical cooperation, product distribution, the elimination of vicious competition ; supervision of members the correct implementation of national laws and regulations,to regulate the industry; member of information communication technology products, cooperation,resource sharing, capital operation, and promote the application of Internet of Things technologies and products,and promote the Internet of Things industrial scale,co-development.9.ConstructionInternet of Things in the practical application to carry out requires the involvement of all walks of life,and need the guidance of the national government as well as related regulations and policies toassist the launching of the Internet of Things has the scale,broad participation,management, technical,and material properties,etc. other features,the technical problem is the most crucial issues of Things billion Bo logistics consulting, Internet of Things technology is an integrated technology, a system not yet which company has overall responsibility for network planning and construction of the entire system, theoretical studies have commenced in all walks of life and the practical application is limited to within the industry. The key is on the planning and design and research and development of the Internet of Things research in the field of RFID,sensors,embedded software, and transmission of data calculation. In general,to carry out the steps of the Internet of things mainly as follows:(1)identified the object attributes,properties, including static and dynamic properties of the static property can be stored directly in the label,the dynamic properties need to start with sensors to detect real-time;(2)the need to identify the equipment to complete the reading of object attributes,and information into a data format suitable for network transmission;(3)the object of information transmitted over the network to the information processing center (processing center may be distributed,such as home computers or mobile phones,may also be centralized,such as China Mobile IDC) by the processing center to complete the object communication calculation.10.key areasInternet of Things 4 key areas:(1)RFID;(2)sensor network;(3)The M2M;(4)integration of the two.11 .TrendIndustry experts believe that the Internet of things on the one hand can improve economic efficiency and significant cost savings; the other hand,can provide technical impetus to global economic recovery. Currently,the United States,the European Union are all invested heavilyin-depth study to explore the Internet of Things. The country is also highly concerned about the emphasis of Things,Industry and Information Technology Ministry in conjunction with the relevant departments are conducting research in a new generation of IT to the formation of policies and measures to support the development of a new generation of IT.China Mobile CEO Wang Jianzhou has repeatedly mentioned the Internet of Things will become the focus of future development of China Mobile. He will be invited to Taiwan to produce RFID,sensors and bar code manufacturers and China Mobile. According to him,the use of the Internet of Things technology,Shanghai Mobile has a number of industrial customers tailor the data collection,transmission,processing and business management in one set of wireless application solutions. The latest data show that Shanghai Mobile has more than 100,000 chips mounted on a taxi,bus,various forms of matter networking applications in all walks of prowess, to ensure the orderly operation of the city. During the Shanghai World Expo, ’’the bus services through’’ will be fully applied to the Shanghai public transport system, the smooth flow traffic to the most advanced technology to protect Expo area; for logistics transportation management,e-logistics n,will provide users with real-time accurate information of Cargo, vehicle tracking and positioning, the transport path selection, logistics network design and optimization services greatly enhance the comprehensive competitiveness of logistics enterprises.In addition,the popularization of the n Internet of Things” for the number of animals,plants and machinery,sensors and RFID tags of items and related interface devices will greatly exceed the number of mobile phones. The promotion of the Internet of Things will become a drive to promote economic development for the industry to open up a potential development opportunities. According to the current demand on the Internet of Things,in recent years, billions of sensors and electronic tags,which will greatly promote the production of IT components,while increasing the number of job opportunities.According to reports, it is necessary to truly build an effective Internet of things, there are two important factors. First, the scale, only with the scale to make the items of intelligence play a role. For example, a city of one million vehicles,if we only 10000 vehicles installed on the smart system, it is impossible to form an intelligent transportation system; two mobility items are usually not static,but in the state of the movement,we must maintain the items in the state of motion,and even high-speed motion state can at any time for dialogue.FORRESTER of the authority of the U.S. advisory body predicted that 2020, the world ofbusiness of the Internet of Things,compared with the business of interpersonal communication,will reach 30 to 1,so the ’’Internet of Things’1 is known to be the next one trillion communications services.Internet of Things heat wave Why is rapidly growing in China? Internet of Things in China rapid rise thanks to the several advantages of our country in terms of things.In the early 1999 launched the Internet of Things core sensor network technology research, R & D level in the world; the second,sensor network field in the world,China is the standard one of the dominant country, the patent owner; third China is one of the countries to achieve a complete industrial chain of Things; F ourth, China’s wireless communications network and broadband coverage provides a solid infrastructure to support the development of the Internet of Things; Fifth, China has become the world’s first the three major economies,with strong economic strength to support the development of the Internet of Things.12.MythThe current understanding of the Internet of things there are a lot of misunderstanding,which is also a direct impact on our understanding of Things on the development of the logistics industry, it is necessary first to distinguish errors, clarify our thinking.One sensor networks or RFID network equivalent of Things. The fact that sensor technology,or RFID technology,or are simply one of the information collection technology. In addition to the sensor technology and RFID technology,GPS, video recognition,infrared,laser,scanning can be achieved automatically identify physical objects to communicate technical information collection technology can become the Internet of Things. Sensor networks or RFID network is just an application of Things,but not all of Things.Second,the Internet of Things as a myriad of unlimited extension of the Internet of Things as a completely open for all things,all of the interconnections,all shared Internet platform.In fact,the Internet of Things is not simple infinite extension of the global sharing of the Internet. Even if the Internet is also not only refers to we typically think of the international sharing computer network,Internet,WAN and LAN. Internet of Things can be both an extension of our usual sense of theInternet to the matter; LAN,professional can also be based on real needs and industrial applications. The reality is not necessary and can not make all the items networking; no need to make professional,LAN must be connected to the global Internet sharing platform. Of things in the future the Internet will be very different from the professional network of similar smart logistics, smart transportation,smart grid; the intelligence community and other local area network is the largest use of space.Ter, that the ubiquitous network of the Internet of Things Internet of Things, and therefore the Internet of Things is a castle in the air, is difficult to achieve the technology. In fact the Internet of things are real,many of the primary Internet of Things applications already for our services. The Internet of Things concept is introduced in many real-world applications based on polymeric integrated innovation,pre-existing network with the Internet of Things, intelligent,automated system, summarized and upgrading it upgraded from a higher perspective our knowledge.Four of Things as a basket,and everything installed inside; based on self-awareness, and only be able to interact, communication products as the Internet of Things applications. For example, just embedded some of the sensors,to become the so-called Internet of Things appliances; products labeled with RFID tags, became the Internet of Things applications.esThings widely used throughout the intelligent transportation, environmental protection,government,public safety, peace at home, smart fire, industrial monitoring, environmental monitoring, elderly care,personal health,floriculture,water monitoring,food traceability,enemydetection and intelligence collection and other fields.International Telecommunication Union in 2005, a report has portrayed the picture of the era of the "Internet of Things": car when the driver operational errors will automatically alarm; briefcase will remind the owner forgot somet hing; clothes will ’’tell” washing machine color and water temperature requirements. Billion Bo logistics consulting vivid introduction of Things in the logistics field,for example, a logistics company,application of Things truck,when loading overweight,the car will automatically tell you overloaded and overload how many, but the space remaining,the severity of。

From the point of view of a private user, the most obvious effects of the IoT introduction will be visible in both working and domestic fields. In this context, domotics, assisted living, e-health, enhanced learning are only a few examples ofpossible application scenarios in which the new paradigm will play a leading role in the near future.物联网理念的主要强大之处在于,它对潜在用户的日常生活和行为的方方面面产生很大影响;从个人用户的角度来看,它最明显的影响就是工作和家庭方面的影响;在这方面,家庭自动化、辅助生活、电子医疗和加强学习只是物联网应用的几个例子,在不久的将来,这种新模式将发挥主导作用;2、Similarly, from the perspective of business users, the most apparent consequences will be equally visible in fields such as, automation and industrial manufacturing, logistics, business/process management, intelligent transportation of people and goods.同样,从企业用户的角度来看,同样会在一些领域产生最显着的影响,如自动化工业制造、物流、业务/流程管理、人员和货物的智能交通;3、In the IoT, "things" are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information "sensed" about the environment, while reacting autonomously to the "real/physical world" events and influencing it by running processes that trigger actions and create services with or without direct human intervention.在物联网中,“物”有望成为商业、信息和社会进程的积极参与者;通过交换数据和“感受到”环境的信息,它们可以进行彼此之间及与环境之间的互动和通信;与此同时,通过运行触发动作、创造服务过程,不管有没有人为干预,来自主反应和影响“真实/物理世界”的事件; 4、As the Internet of Things is different from Internet and Telecommunications Network, the above two models is not suitable for IoT directly. But they have some similar features in common. So through the technology architecture of the Internet and the logical structure of Telecommunications Management Network and combined with the specific features of the Internet of Things, we established anew architecture of IoT.由于物联网不同于互联网和电信网络,所以这两种模式不能直接适用于物联网;但是它们有一些相似的共同特征;所以凭借互联网的技术架构和电信管理网络的逻辑结构,再结合物联网的具体特征,我们建立了一个新的物联网架构;5、We believe that this architecture would better explain the features and connotation of the Internet of Things. We divided IoT into 5 layers, which are the Business Layer, the Application Layer, the Processing Layer, the Transport Layer and the Perception Layer.我们相信,这种架构将更好地解释物联的内涵和特征;我们将物联网分为5层:业务层,应用层,处理层,传输层和感知层;6、We think the existing 3-layer structure has certain significance to understand technical architecture of the Internet of Things at the initial stage of its development, but it cannot completely explain its structure and the connotation. Just because of this, many scholars have different opinions on the definition and scope of the Internet of Things.我们认为,在物联网发展的初级阶段,现有的三层结构对了解技术架构方面具有重要意义,但是并不能完全解释物联网的结构和内涵;正因为如此,许多学者在物联网的定义和范畴上持不同意见;7、Such micro-silicon sensor is an advanced sensor technology nowadays. Its basic advantage is that the sensitive components' volume is micron sized, which is one-tenths or one-hundredths of that in traditional sensors. Hence it plays an important role in the fields of industrial control, aerospace, biomedicine etc. Another advantage is its high sensitivity which makes minuteness measurement possible. For example, it could serve as blood pressure sensor.像这样的硅微传感器是当今传感器发展的前沿技术,其基本特点是敏感元件体积为微米量级,是传统传感器的几十、几百分之一;在工业控制、航空航天领域、生物医学等方面有重要的作用;另一特点是敏感度高,使得微小量可被测量,可制成血压压力传感器;8、Traditional sensor could not rival integrated sensor in many respects.Integrated sensor is not only a simple sensor but also a chip, in which there are auxiliary components and sensors, with the function of calibration, compensation, self-diagnosis and network communication. It has lower cost to increase the quantity of production. American LUCAS, NOVASENSOR Inc. produces 10,000 integrated blood pressure sensors per week.在很多方面,集成传感器的优势是传统传感器无法竞争的,它不仅仅是一个简单的传感器,更是一个将辅助元件与传感器同时集成在一块的芯片,使之具有标定、补偿、自诊断和网络通信的功能,它可降低成本、增加产量,美国LUCAS、NOVASENSOR公司每星期能生产1万只这种集成血压传感器;9、The technology behind RFID uses inductive coupling to transfer data. Induction occurs when a wire or any other conductor of electricity passes through a magnetic field, generating an electric current in the wire. It is similar to the principal of electromagnetism-that passing an electric current through a coil of wire will generate a magnetic field-only in reverse. An RFID chip has a coil of wire built into it. An electric current jumps between the two coils of wire,signaling data-carrying, short-range radio waves to pass between the two devices. RFID技术利用电感耦合来传输数据;当电线或其它任何导体通过磁场会产生电感,从而在电线中形成电流;这与电磁原理相似,电流通过线圈将形成磁场—只不过是一个相反过程;RFID芯片内部封装有线圈,电流在两个线圈之间传递,携带的数据信号利用短距离无线电波在两个设备之间传输;10、Barcode is the varying width of the black bars and blank, arranged according to the encoding rules for the expression of a set of information graphics identifier. The common barcode is reflectivity big difference between black bars and the white empty arranged in parallel line pattern. Barcodes can be marked goods producers, manufacturers, product name, production date, number of books, mail starting and ending location, category, date and other information.条形码是将由宽度不等的多个黑条和空白,按照一定的编码规则排列,用以表达一组信息的图形标识符;常见的条形码是由反射率相差很大的黑条和白条空排列成的平行线图案;条形码可以标出物品的生产国、制造厂家、产品名称、生产日期、图书分类号、邮件起止地点、类别、日期等许多信息;11、There are three types of ZigBee devices: ZigBee coordinator, ZigBee router, and ZigBee end device. ZigBee coordinator initiates network formation, stores information, and can bridge networks together. ZigBee routers link groups of devices together and provide multi-hop communication across devices. ZigBee end-device consists of the sensors, actuators, and controllers that collects data and communicates only with the router or the coordinator.ZigBee设备有3种类型:ZigBee协调器,ZigBee路由器和ZigBee终端设备;ZigBee协调器负责网路的形成、信息存储和桥接网络;ZigBee路由器将多组设备联系在一起,提供不同设备间多跳式通信;终端设备由传感器、执行器、控制器组成,可以收集数据,只能和路由器或者协调器进行通信;。

"Chinese style" as defined inInternet of Things (Internet of Things) refers to is the ubiquitous (Ubiquitous) terminal equipment (Devices) and facilities (Facilities), including with the "inner intelligence" sensors, mobile terminals, industrial systems, floor control system, the family of Intelligentfacilities, video surveillance systems, and external can "(Enabled), such as RFID, a variety of assets (the Assets), personal and vehicle carrying the wireless terminal" intelligent objects or animals "or" smart dust "(the Mote), through a variety of wireless and / or cable over long distances and / or short-range communication networks to achieve interoperability (M2M), application integration (the Grand Integration), and based on cloud computing, SaaS operation mode, in internal network (intranet), private network (extranet), and / or the Internet (Internet) environment, the use of appropriate information security mechanisms to provide a safe, controlled and even personalized real-time online monitoring, retrospective positioning, alarm linkage, command and control plan management, remote control, security, remote repair and maintenance, online upgrades, statistical reporting, decision support, the leadership of the desktop (showcase of the Cockpit Dashboard) management and service functions, "Everything," "efficient, energy saving, security environmental protection, "" possession, control, Camp integration [1].4.EU definitionIn September 2009, the Internet of Things and enterprise environments held in Beijing, China-EU Seminar on the European Commission and Social Media Division RFID Division is responsible for Dr. Lorent Ferderix, given the EU's definition of things: the Internet of Things is a dynamic global network infrastructure, it has a standards-based and interoperable communication protocols, self-organizing capabilities, including physical and virtual "objects" of identity, physical attributes, virtual features and smart interface and seamless integration of information networks .Internet of Things Internet and media, the Internet and business Internet one, constitute the future of the Internet.5.changeThe Internet of Things (Internet of Things) the word universally recognized at home and abroad Ashton, Professor of the MIT Auto-ID Center in 1999 first proposed to study RFID. The report of the same name released in 2005, the International Telecommunication Union (ITU), the definition and scope of the Internet of Things has been a change in the coverage of a larger expansion, no longer refers only to the Internet of Things based on RFID technology.Since August 2009, Premier Wen Jiabao put forward the "Experience China" Internet of Things was officially listed as a national one of the five emerging strategic industries, to write the "Government Work Report" Internet of Things in China has been the great concern of the society as a whole degree of concern is unparalleled in the United States, European Union, as well as other countries.The concept of Internet of Things is not so much a foreign concept, as it has been the concept of a "Made in China", his coverage of the times, has gone beyond the scope of the 1999 Ashton professor and the 2005 ITU report referred to, Internet of Things has been labeled a "Chinese style" label.6.BackgroundThe concept of Internet of Things in 1999. Internet-based, RFID technology and EPC standards, on the basis of the computer Internet, the use of radio frequency identification technology, wireless data communication technology, a global items of information to real-time sharing of the physical Internet "Internet of things" (referred to as the Internet of Things) , which is also the basis of the first round of the China Internet of Things boom set off in 2003.The sensor network is built up based on sensing technology network. Chinese Academy of Sciences in 1999 on the start sensor network research and has made some achievements in scientific research, the establishment of applicable sensor network.1999, held in the United States, mobile computing and networking International Conference, "The sensor network is a development opportunity facing humanity in the next century. In 2003, the United States, "Technology Review" proposed sensor network technology will be future changes ten people's lives first.November 17, 2005, the WSIS held in Tunis (WSIS), the International TelecommunicationUnion released ITU Internet Report 2005: Internet of Things ", citing the concept of the" Internet of things ". The report pointed out that the ubiquitous "Internet of Things" communication era is approaching, all the objects in the world, from tires to toothbrushes, from housing to the tissue via the Internet, take the initiative to be exchanged. Radio Frequency Identification (RFID), sensor technology, nanotechnology, intelligent embedded technology will be more widely used.According to the description of the ITU, the era of things, a short-range mobile transceivers embedded in a variety of daily necessities, human beings in the world of information and communication will receive a new communication dimension, from any time communication between people of the place of connection extended to the communication connection between persons and things and things and things. The Internet of Things concept of the rise, largely due to the International Telecommunication Union (ITU), the title of Internet of Things 2005 annual Internet Report. However, the ITU report the lack of a clear definition of Things.Domestic Internet of Things is also there is no single standard definition, but the Internet of Things In essence, the Internet of Things is a polymer application of modern information technology to a certain stage of development and technological upgrading of various sensing technology modern network technology and artificial intelligence and automation technology aggregation and integration of applications, so that the human and material wisdom of dialogue to create a world of wisdom. Because the development of the Internet of Things technology, involving almost all aspects of IT, innovative application and development of a polymer, systematic, and therefore be called revolutionary innovation of information industry. Summed up the nature of the Internet of Things is mainly reflected in three aspects: First, the Internet features that need to be networked objects must be able to achieve the interoperability of the Internet; identification and communication features, that is included in the Internet of Things "objects" must to have the functions of automatic identification and physical objects communication (M2M); intelligent features, the network system should have automated, self-feedback and intelligent control features January 28, 2009, Obama became the President of the United States, held with U.S. business leaders a "round table", as one of the only two representatives, IBM CEO Sam Palmisano for the first time that "the wisdom of the Earth" this concept, it is recommended that the new government to invest in a new generation of intelligent infrastructure.February 24, 2009 news, IBM Greater China CEO money crowd called "Smarter Planet"strategy announced in the forum 2009IBM.This concept was put forth, that is the great concern of the United States from all walks of life, and even analysts believe that IBM's vision is very likely to rise to U.S. national strategy, and caused a sensation in the world. IBM believes that the industry, the next phase of the mission is to make full use of the new generation of IT technology in all walks of life among specifically, is the embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water supply systems dams, oil and gas pipelines and other objects, and is generally connected to the formation of Things.Strategy conference, IBM, and implant the concept of "wisdom" in the implementation of the infrastructure, strong, not only in the short term to stimulate the economy, promote employment, and in a short period of time for China to build a mature wisdom infrastructure platform.IBM "Smarter Planet" strategy will set off again after the wave of Internet technology industrial revolution. Former IBM CEO Lou Gerstner has raised an important point of view, every 15 years, a revolution in computing model. This judgment is the same as Moore's Law accurately call it a "15-year cycle Law". Before and after 1965, changes to the mainframe as a symbol, 1980 marked by the popularization of personal computers, 1995, the Internet revolution. Each such technological change are caused by the enterprise, industry and even the national competitive landscape of major upheaval and change. To a certain extent in the Internet revolution is ripening by the "information superhighway" strategy. 1990s, the Clinton administration plan for 20 years, $ 200 billion to -4000 billion, construction of the U.S. National Information Infrastructure, to create a huge economic and social benefits.Today, the "Smarter Planet" strategy by many Americans that there are many similarities with the "information superhighway", the same they revive the economy, a key strategy for competitive advantage. The strategy can be set off, not only for the United States, such as the Internet revolution was the wave of technological and economic concern, more attention from the world."Internet of Things prospects are very bright, it will dramatically change our current way of life." Demonstration director of the Center of Nanjing University of Aeronautics and Astronautics, National Electrical and Electronic Zhao Guoan said. Industry experts said that the Internet of things to our life personification of the things became a kind of human.Goods (goods) in the world of physical objects associated with each other "exchange", without the need for human intervention.The Internet of Things using radio frequency identification (RFID) technology, to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet. It can be said that the Internet of Things depict the world is full of intelligent. In the world of Internet of Things, material objects connected to the dragnet.The second session, held at Peking University in November 2008, China Mobile Government Seminar "Knowledge Society and Innovation 2.0", the experts made the mobile technology, the Internet of Things technology led to the development of economic and social form, innovative forms of change, and promote the The next generation of innovation for the knowledge society as the core of user experience (innovative 2.0) the formation of innovation and development of the form to pay more attention to the user to focus on people-oriented. Research institutions is expected to 10 years, the Internet of Things may be mass adoption of this technology will develop into one of thousands of yuan-scale high-tech market, the industry than the Internet 30 times.It is learned that the things industry chain can be broken down into the identity, perception, processing and information transfer, four links, each link of the key technologies for the wireless transmission network of RFID, sensors, smart chip and telecom operators. EPOSS in the "Internet of Things in 2020" report, an analysis predicted that the future development of the Internet of Things will go through four stages, 2010, RFID is widely used in the field of logistics, retail and pharmaceutical objects interconnect 2010 to 2015, 2015 ~ In 2020, the object into the semi-intelligent, intelligent objects into 2020.As the vanguard of the Internet of Things, RFID has become the most concerned about the technology market. The data show that the global RFID market size in 2008 from $ 4.93 billion in 2007 rose to $ 5.29 billion, this figure covers all aspects of the RFID market, including tags, readers and other infrastructure, software and services. RFID card and card-related infrastructure will account for 57.3 percent of the market, reaching $ 3.03 billion. Application from financial and security industries will drive the market growth of RFID cards. Analysys International forecasts, the Chinese RFID market size in 2009 will reach 5.0 billion, a CAGR of 33%, in which the electronic tag is more than 3.8 billion yuan, the reader close to 700 million yuan, software and services market to reach 500 million yuan pattern.MEMS is the abbreviation of the micro-electromechanical systems, MEMS technology is built on the basis of micro / nano, the market prospect is broad. The main advantage of the MEMS sensoris the small size, large-scale mass production cost reduction, mainly used in two major areas of automotive and consumer electronics. Under ICInsight the latest report is expected in 2007-2012, global sales of semiconductor sensors and actuators based on MEMS will reach 19 percent compound annual growth rate (CAGR), compared with $ 4.1 billion in 2007 to five years will achieve $ 9.7 billion in annual sales.7.PrincipleInternet of Things is on the basis of the computer Internet, RFID, wireless data communications technology, to construct a cover everything in the world's "Internet of Things". In this network, the goods (products) to each other "exchange", without the need for human intervention. Its essence is the use of radio frequency identification (RFID) technology to achieve the interconnection and sharing of the automatic identification of goods (products) and information through the computer Internet.The Internet of Things is a very important technology is radio frequency identification (RFID) technology. RFID is radio frequency identification (Radio Frequency Identification) technology abbreviation, is an automatic identification technology in the 1990s began to rise, the more advanced a non-contact identification technology. The development of RFID technology based on a simple RFID system, combined with existing network technology, database technology, middleware technology, to build a one composed by a large number of networked readers and numerous mobile label, much larger than the Internet of Things trend.RFID, It is able to let items "speak" a technique. In the "Internet of Things" concept, RFID tags are stored in the specification and interoperability information collected automatically by wireless data communications network to a central information system, to achieve the identification of goods (products), and then through the open computer network for information exchange and sharing, items "transparent" management.The information technology revolution in the Internet of Things is referred to as IT mobile Pan of a specific application. Internet of Things through IntelliSense, identification technology and pervasive computing, ubiquitous network convergence applications, breaking the conventional thinking before, human beings can achieve ubiquitous computing and network connectivity [3]. The traditional thinking has been the separation of physical infrastructure and IT infrastructure: on the one hand, airports, roads, buildings, while on the other hand, the data center, PC, broadband. In theera of the "Internet of Things", reinforced concrete, cable with the chip, broadband integration into a unified infrastructure, in this sense, the infrastructure is more like a new site of the Earth, the world really works it, which including economic management, production operation, social and even personal life. "Internet of Things" makes it much more refined and dynamic management of production and life, to manage the future of the city to achieve the status of "wisdom" to improve resource utilization and productivity levels, and improve the relationship between man and nature. 8.Agency1, institution-buildingAs the first national Internet of Things industry community organizations - the application of professional Committee of China Electronic Chamber of Things technology products (referred to as: "objects of the IPCC"), the Ministry of Civil Affairs in June 2010, preliminary approved by the Ministry of August being reported that the Ministry of Civil Affairs for final approval.2, the main taskServe as a bridge between business and government to assist the Government of the industry guidance, coordination, consultation and services to help members to reflect the business requirements to the Government; coordinate the relationship between enterprises to strengthen technical cooperation, product distribution, the elimination of vicious competition ; supervision of members the correct implementation of national laws and regulations, to regulate the industry; member of information communication technology products, cooperation, resource sharing, capital operation, and promote the application of Internet of Things technologies and products, and promote the Internet of Things industrial scale , co-development.9.ConstructionInternet of Things in the practical application to carry out requires the involvement of all walks of life, and need the guidance of the national government as well as related regulations and policies to assist the launching of the Internet of Things has the scale, broad participation, management, technical, and material properties, etc. other features, the technical problem is the most crucial issues of Things billion Bo logistics consulting, Internet of Things technology is an integrated technology, a system not yet which company has overall responsibility for network planning and construction of the entire system, theoretical studies have commenced in all walks of life and the practical application is limited to within the industry. The key is on the planning and design andresearch and development of the Internet of Things research in the field of RFID, sensors, embedded software, and transmission of data calculation. In general, to carry out the steps of the Internet of things mainly as follows:(1) identified the object attributes, properties, including static and dynamic properties of the static property can be stored directly in the label, the dynamic properties need to start with sensors to detect real-time;(2) the need to identify the equipment to complete the reading of object attributes, and information into a data format suitable for network transmission;(3) the object of information transmitted over the network to the information processing center (processing center may be distributed, such as home computers or mobile phones, may also be centralized, such as China Mobile IDC) by the processing center to complete the object communication calculation.10.key areasInternet of Things 4 key areas:(1) RFID;(2) sensor network;(3) The M2M;(4) integration of the two.11.TrendIndustry experts believe that the Internet of things on the one hand can improve economic efficiency and significant cost savings; the other hand, can provide technical impetus to global economic recovery. Currently, the United States, the European Union are all invested heavily in-depth study to explore the Internet of Things. The country is also highly concerned about the emphasis of Things, Industry and Information Technology Ministry in conjunction with the relevant departments are conducting research in a new generation of IT to the formation of policies and measures to support the development of a new generation of IT.China Mobile CEO Wang Jianzhou has repeatedly mentioned the Internet of Things will become the focus of future development of China Mobile. He will be invited to Taiwan to produce RFID, sensors and bar code manufacturers and China Mobile. According to him, the use of the Internet of Things technology, Shanghai Mobile has a number of industrial customers tailor the datacollection, transmission, processing and business management in one set of wireless application solutions. The latest data show that Shanghai Mobile has more than 100,000 chips mounted on a taxi, bus, various forms of matter networking applications in all walks of prowess, to ensure the orderly operation of the city. During the Shanghai World Expo, "the bus services through" will be fully applied to the Shanghai public transport system, the smooth flow traffic to the most advanced technology to protect Expo area; for logistics transportation management, e-logistics ", will provide users with real-time accurate information of Cargo, vehicle tracking and positioning, the transport path selection, logistics network design and optimization services greatly enhance the comprehensive competitiveness of logistics enterprises.In addition, the popularization of the "Internet of Things" for the number of animals, plants and machinery, sensors and RFID tags of items and related interface devices will greatly exceed the number of mobile phones. The promotion of the Internet of Things will become a drive to promote economic development for the industry to open up a potential development opportunities. According to the current demand on the Internet of Things, in recent years, billions of sensors and electronic tags, which will greatly promote the production of IT components, while increasing the number of job opportunities.According to reports, it is necessary to truly build an effective Internet of things, there are two important factors. First, the scale, only with the scale to make the items of intelligence play a role. For example, a city of one million vehicles, if we only 10000 vehicles installed on the smart system, it is impossible to form an intelligent transportation system; two mobility items are usually not static, but in the state of the movement , we must maintain the items in the state of motion, and even high-speed motion state can at any time for dialogue.FORRESTER of the authority of the U.S. advisory body predicted that 2020, the world of business of the Internet of Things, compared with the business of interpersonal communication, will reach 30 to 1, so the "Internet of Things" is known to be the next one trillion communications services.Internet of Things heat wave Why is rapidly growing in China? Internet of Things in China rapid rise thanks to the several advantages of our country in terms of things.In the early 1999 launched the Internet of Things core sensor network technology research, R & D level in the world; the second, sensor network field in the world, China is the standard one ofthe dominant country, the patent owner; third China is one of the countries to achieve a complete industrial chain of Things; Fourth, China's wireless communications network and broadband coverage provides a solid infrastructure to support the development of the Internet of Things; Fifth, China has become the world's first the three major economies, with strong economic strength to support the development of the Internet of Things.12.MythThe current understanding of the Internet of things there are a lot of misunderstanding, which is also a direct impact on our understanding of Things on the development of the logistics industry, it is necessary first to distinguish errors, clarify our thinking.One sensor networks or RFID network equivalent of Things. The fact that sensor technology, or RFID technology, or are simply one of the information collection technology. In addition to the sensor technology and RFID technology, GPS, video recognition, infrared, laser, scanning can be achieved automatically identify physical objects to communicate technical information collection technology can become the Internet of Things. Sensor networks or RFID network is just an application of Things, but not all of Things.Second, the Internet of Things as a myriad of unlimited extension of the Internet of Things as a completely open for all things, all of the interconnections, all shared Internet platform.In fact, the Internet of Things is not simple infinite extension of the global sharing of the Internet. Even if the Internet is also not only refers to we typically think of the international sharing computer network, Internet, WAN and LAN. Internet of Things can be both an extension of our usual sense of the Internet to the matter; LAN, professional can also be based on real needs and industrial applications. The reality is not necessary and can not make all the items networking; no need to make professional, LAN must be connected to the global Internet sharing platform. Of things in the future the Internet will be very different from the professional network of similar smart logistics, smart transportation, smart grid; the intelligence community and other local area network is the largest use of space.Ter, that the ubiquitous network of the Internet of Things Internet of Things, and therefore the Internet of Things is a castle in the air, is difficult to achieve the technology. In fact the Internet of things are real, many of the primary Internet of Things applications already for our services. The Internet of Things concept is introduced in many real-world applications based on polymericintegrated innovation, pre-existing network with the Internet of Things, intelligent, automated system, summarized and upgrading it upgraded from a higher perspective our knowledge.Four of Things as a basket, and everything installed inside; based on self-awareness, and only be able to interact, communication products as the Internet of Things applications. For example, just embedded some of the sensors, to become the so-called Internet of Things appliances; products labeled with RFID tags, became the Internet of Things applications.esThings widely used throughout the intelligent transportation, environmental protection, government, public safety, peace at home, smart fire, industrial monitoring, environmental monitoring, elderly care, personal health, floriculture, water monitoring, food traceability, enemy detection and intelligence collection and other fields.International Telecommunication Union in 2005, a report has portrayed the picture of the era of the "Internet of Things": car when the driver operational errors will automatically alarm; briefcase will remind the owner forgot something; clothes will "tell" washing machine color and water temperature requirements. Billion Bo logistics consulting vivid introduction of Things in the logistics field, for example, a logistics company, application of Things truck, when loading overweight, the car will automatically tell you overloaded and overload how many, but the space remaining , the severity of goods with how to tell you; when handling staff unloading a cargo packaging may be shouting "throw you hurt me", or "My dear, you do not get too barbaric, you can?"; when the driver and others gossip, trucks will pretend boss's voice roaring "stupid, the grid!Internet of things to make full use of a new generation of IT technology in all walks of life among, specifically, is embedded sensors and equipment to the power grid, railways, bridges, tunnels, highways, buildings, water systems, dams, oil and gas pipelines, etc.kinds of objects, and then "Internet of Things" with the existing Internet to integrate and realize the integration of human society and the physical system, which in this integrated network, there is the ability to super-powerful central computer cluster, integrated network staff implementation of real-time management and control of the machinery, equipment and infrastructure, on this basis, the human can be more refined and dynamic management of production and life, to achieve the status of the "wisdom", to improve resource utilization and productivity levels, and improve human the relationship between the natural.。

物联网的基本概念、核心技术和信息安全一、物联网发展概述二、物联网基本概念三、物联网核心技术四、物联网信息安全五、物联网几点讨论六、物联网发展展望一、物联网发展概述一般认为,物联网的基本概念,最早于1999年由美国麻省理工学院Kevin Ashton、Sanjay Sarma和David Brock提出,其核心思想是基于互联网、RFID(Radio Frequency Identification,无线射频识别)技术、EPC(Electronic Product Code,电子产品编码)标准(一个网络、一项技术、一个标准),在计算机互联网的基础上,利用无线射频识别技术、无线数据通信技术等,构造一个实现全球物品信息实时共享的实物互联网——“Internet of Things”(简称物联网)。
自1999年到2003年,美国麻省理工学院的Auto-ID中心完成了EPC应用方面三个阶段(货堆、货箱、单个物品)的示范实验,从实验室走向实际应用。
2005年11月17日,在突尼斯举行的信息社会世界峰会(WSIS)上,国际电信联盟(ITU)发布了《ITU互联网报告2005:物联网》。
报告引用了上述“物联网”这一名称,但其定义和范围已经发生了重要变化,覆盖范围有了较大扩展;报告中的“物联网”不再只是指基于RFID技术的物联网;报告指出,信息与通信技术的目标已经从任何时间、任何地点连接任何人,发展到连接任何人与物品的阶段,世界上所有物体——从轮胎到牙刷都将纳入通信领域;无所不在的“物联网”通信时代即将到来;无线射频识别技术、传感器技术、纳米技术、智能嵌入技术将得到更加广泛的应用。
在国内,随着政府对物联网产业的关注和支持力度的明显增强,物联网已经从产业愿景走向现实应用。
物联网前期在中国更多地被认为是传感网。
1999年,中国科学院启动了传感网研究计划,取得了一批科研成果,建立了一些适用的传感器网络,目前已拥有从材料、技术、器件、系统到网络的完整产业链。
一个基于网络的分布式电能质量测量系统评估文章历史:2008年6月17日此文章被接收2010年1月4日修订后的文章被接收2010年2月17日此文章被接受2010年2月21日此文章发布于网上摘要:行业的系统几乎完全转向复杂的电子设备。
电能质量(PQ)分析对经济变得很重要,因为该设备对电能质量事件很灵敏。
一个工业过程的主要控制和监督主要已经被集中在电气保护上,电力供应的质量很少被关注。
如今,测量和通信系统已经发展到能够使基于网络的传感器安装在PQ评估场景上。
在某种意义上,本文提出了一种创新的低成本的测量系统,并研究了使用智能传感器的的分布式电能质量测量系统的发展的挑战性和趋势。
关键词:分布式测量系统,电能质量(PQ),智能传感器1.介绍随着越来越多的电子设备进入住宅和商业环境,与电能质量(PQ)及其关联的安装的脆弱性是用户越来越关心的问题。
电能质量主要包括两个方面:技术方面的电能质量,包括供应的连续或性可靠性(持续中断)和电压质量(VQ),其中电压质量包括电压水平变化和电压扰动。
与电线相关的商业服务(比如连接到电网的延迟等等)以及管理客户的能源零售的商业服务。
当电压下降到零超过一分钟时发生持续中断,持续中断是可靠性问题,而对此消费者有最很深的亲身经验。
持续中断也是在传统的公用事业服务的质量和可靠性统计数据的衡量时的关键现象。
系统平均中断频率指标(SAIFI)和客户平均中断持续时间指数(CAIDI)等指标不捕捉电能质量扰动。
电压质量和功率扰动的评估包括观察电压或电流的电磁偏差。
此电压或电流是从理想的单频正弦波的固定振幅和频率得到的。
设备操作面临电压质量问题,电压质量问题包括顺变、凹陷、膨胀、激增、中断、谐波和不同数量或程度的电压脉冲[1]。
一组一致的定义可以在[2]。
电力供应的质量由公用事业传送,电力供应的质量变化相当大,这取决于很多的外界因素。
像闪电、工业场所类的事物应用应用和删除大负荷,非线性负荷压力,不足或错误的布线和接地或者由动物、树枝、车辆因素、人类电气线路事故引起的短路。
一些电力供应商决定遵守如[3]中所成立的条例。
所有类别的干扰,如电压凹陷(浸)和瞬时中断是自动化工业过程[4]的敌人。
电压凹陷通常定义为在10%和90%之间的名义电压的任何低电压,该名义电压持续半个到六十个周期。
另一方面,电压增长(这不常见)通常不会破坏敏感负载,但能对设备造成危害。
瞬时电压中断是低于名义电压的10%的任何低电压,该名义电压持续半个到三个周期。
电压凹陷可由自然事件(比如树压倒在电线上或闪电击中电线或变压器),公用事业活动(比如常规切换、人为错误)或客户活动(比如大型汽车的起动)。
在客户公共汽车上的电压跌落依据它在电子网络[5]中的位置而不同。
由于那些电能质量时间的瞬时性,住宅的客户很少意识到电压质量事件已近发生。
然而,对于许多工业客户提出更有意义的问题而不是中断。
因为他们发生频率高和整体因为事故会导致数小时的停机[6]。
85%的电力供应故障归咎于不良的电压质量,电压质量由电压凹陷或持续一两秒的中断。
与不受监管的线电压(尤其是长期电压降落)相关的一些主要问题包括设备跳闸、停滞、过热和敏感设备的完全关闭。
如果是设计在狭窄的电压范围内操作,或者没有足够的脱网运行功能来过滤掉电源波动。
这些随后导致低效率、高电力需求,更高的电力成本,电磁干扰控制电路,过度加热电缆和设备,增加设备损坏的风险。
线电压调整的需要仍然是一个需要满足高要求的工业生产力。
目前在市场上有几种调节方案了。
其中最常见的是无中断电源系统(UPS)。
最近,新技术基于电力电子理念的定制的电力设备已经发展到对电能质量问题[7]给予保护了。
但是提高电能质量最大的障碍是缺乏现在的和历史的电能质量数据[8]。
标准EC 61000-4-30[9]的建立是为了定义测量和电压质量参数[10]的解释方法。
对于每个相关类型的扰动的测量方法都已经建立。
两个不同的类测量设备是根据其准确性定义的。
A类设备使用时,精确测量是必要的。
比如对于合同应用程序,验证符合标准,解决争端等。
B类计量器具用于确定统计值和规范/矫正错误(故障)。
一个适当的监控系统,基于连续原理能够观察电能质量现象是必要的,因为源干扰的发生是高度不可预知的[10]。
先进的电能质量测量设备的的主要特点和趋势可以在[11-13]找到。
最后几年也提出一些实验解决方案。
在[14],关于部分建筑低压网络的标准虚拟仪器TCP / IP技术运用到了该系统。
部分低压建筑网络可以被简化成具有代表性的更大的网络。
和之前一样,系统硬件在[15]由几个电脑组成,每个电脑都托管一个数据采集板(DAQ)。
数据采集板通过电压传感器与电力系统连接。
软件实现不同的虚拟仪器,虚拟仪器使用众所周知的倪虚拟仪器图形化编程语言。
此外,目前许多公用事业利用专用的电力质量监督设备,该设备可以结合高,中压站检测电能质量事件[16]。
具有里程碑意义之一的是在过去十年建立了电力科学研究院。
然而,现在安装的最广泛的扩展基础设施详见[18]。
一方面,目前许多自动化工厂使用专用的电能质量测量设备但是是为了公共连接点(PCC)和确定在电能质量事故中程序的任务。
实证研究很少,但是,整合工厂内部的分散的测量数据的角度看是可行的。
总之需要一种能够在连续观察电能质量的现象的基础上的低成本系统。
这是必要的,因为大多数的隐患来自不太可能的事情,比如操作现在工厂设备或者不正确的布线方案。
尽管所有重大事件可以被获悉,但是导致能从非重要的事情中得到过多的数据。
维护工程师必须整理这个数据来分析电能质量干扰。
手动方法是昂贵的,耗时的,而且容易出错。
为了每个网站反复分析数据而开发的软件在开发、维护是很昂贵的。
而且依据他们底层架构难以扩大。
因此设计一种能够分析,整合,解释大量的原始数据的系统,该数据可以使挑战极限的水平被评估,被扩展,这将称为在电能质量测量领域称为最的挑战。
本文介绍了一种创新、低成本的、基于物联网的电能质量测量仪器,它适用于在工业或商业工厂连续的电能质量的测量。
本文结构如下:第二节总结在设计开发的策略。
第三节中描述传感器配置。
第四节详细描述了相关的测量误差。
第五节论证了定时协议兼容性。
第六节描述了操作系统。
最后,第七节综述了全文。
2.设计策略2.1.需求这种基于物联网的测量系统作为高科技,它依赖于有很多低成本传感器、电能质量看门狗、整个工厂分散的网络组成广泛系统。
他们能够持续监测能源耗费也能测量电能质量的详细数据,这些数据包括停机、停电、限电中断、短期障碍,如电压凹陷和膨胀。
除了这些特性外,节约能源的先进功能和能源利用率的提高都得以实现。
从工厂内部的众多节点整合所有电能质量测量数据也是有可能。
从电能质量检测传感器得到的数据可以识别电能质量事件并决定在每台机器上的执行动作。
此外,因为所有的数据都是来自所有的监视器,这些数据通过互联网上传的。
我们可以从多个显示器得到的数据关联在一起,并确定在一个节点记录的事件是否能被检测到或对其他的有影响。
从这个信息,我们将决定时间的起因和事件对公司的影响(停机时间、成本),最后对该实用程序得出结论。
电能质量的扰动范围可以从由点雷击引起的高频率脉冲到由不良电压引起的长时间过电压。
测量装置也会影响测量参数的选择。
广泛来说,这些传感器将测量以下量:电压和电流、有功功率、视在功率、总无功功率、基频无功功率、能源使用、成本、功率因数、总谐波、电源电压的畸变(THD),最重要的谐波电压、供电电压的频率、介于三个阶段之间的电压不平衡。
另外的测量量是电压膨胀、凹陷和中断。
记录间隔可以设置为一些秒、分钟或小时。
最简单的电能质量监控器只能记录上述电量、电压和电流的变化。
在线和离线必须都能进行数据分析。
在线分析用于变化比较快的事件的分析(比如凹陷或中断)。
在线数据分析可以被设备本身执行或者把信息立即送到中央处理位置。
为了减少过多的数据,事故被分成以下类别:瞬变、中断或电压凹陷和膨胀。
存在同一时间接收到几个故障的报警信号的可能性,所以有必要使用某种“分配计分板”排名算法。
该算法能自动分类。
这可以通过使用不同标准的算法执行,比如最大时间、最大幅值变化或最大能量变化。
关于离线电能质量的分析,一个报告通常包含以下信息:·稳态变化的统计数据(电压水平,谐波、不平衡或闪烁)。
·由偶然事件引发的事故的数据(凹陷,短暂的中断,膨胀,或瞬态)。
·可能原因的干扰的识别·电磁兼容性、设备和安装水平的表征·能够减低成本和维护解决方案的建议此外,有必要扩展类似这个报告的活动,有必要区分局部类似的详细观点和全局的观点。
这样电能质量数据管理的系统程序的发展一般支持分散电能质量的调查报告:·网站报告(如详细充分的质量报告,无功功率补偿的构思、各种设备的使用说明)。
·工厂网络报告(例如给简单的网站所有测量、投资计划、电压下降的管理和其他干扰的索引,提供相关事件记录。
这些记录在地理位置分散的位置)。
在所有的情况下,报告是不同于变化量和事件的,变化网站指数是平均数量事件而活动网站指数是根据活动而技术的。
2.2.方法基于网络实现的系统遵循三个步骤。
首先,获取以一定采样频率和分辨率采样得到的电压。
对于每一个事件,电压是采样由频率(以两秒或一个周期为样本建立的)和分辨率决定的。
分辨率定义为波特率。
许多商业的电能质量测量仪器以每周期采样256次采样,因为多数事件的频率低于5兆赫兹。
示波器的数据为工程故障提供最详细的信息,该工程没有记忆存储功能。
其次,它计算事件特新作为从采集电压中得到的时间函数,这个特性包括有效值电压、均方根电流、零序、有功和无功功率、谐波失真水平、基波成分。
对于三个阶段多的测量,三个阶段的三个电压给出不同时间曲线。
从这三个函数得到另外的特性是有必要的。
为达到这个目标已经提出了几种方法。
尽管[10]主要是基于单相测量,通过多通道测量。
当计算单时间指数时采取最糟糕的阶段。
这将在下面给与分析。
作为一个补充,事件持续的测量可以在一个通道开始,在另外一个通道终止。
这是凹陷特性的方法,这也可以扩展到干扰和膨胀。
程序可以减少重复计数,被称作“相聚合”技术。
最后,这种方法计算从事件和变量特性中得到的单条曲线,重点包括检索数据的分析所需的时间。
电能质量数据可以重新被计算,插入到目录中,可以被SCADA收集和存储。
这包括在峰值持续时间表里的电压凹陷和膨胀,暂态表包括最大电压、瞬时状态态对应的时间、瞬时频率、基于CBEMA ITIC的最大值持续时间散点图、用户指定值持续时间散点曲线[19]。
此外它可以提供数据分析。
数据分析包括最小的、平均的、最大的、标准偏差、计数、累积的概率水平。
这是必要的谐波指标。
