The Access control systemAccess control system is widely used in recent years and it is one of the high-tech and safety equipment , has become one of the intelligent signs of modern architecture. Access control , the export and the entrance control system, is to control the export and entrance channel system. Access control system is developed on the basis of the traditional locks (Entrance Guard/Access Control in English).Access control is, in reality, an everyday phenomenon. A lock on a car door is essentially a form of access control. A PIN on an ATM system at a bank is another means of access control. Bouncers standing in front of a night club is perhaps a more primitive mode of access control (given the evident lack of information technology involved). The possession of access control is of prime importance when persons seek to secure important, confidential, or sensitive information and equipment .Item control or electronic key management is an area within (and possibly integrated with) an access control system which concerns the managing of possession and location of small assets or physical (mechanical) keys.Physical access by a person may be allowed depending on payment, authorization, etc. Also there may be one-way traffic of people. These can be enforced by personnel such as a border guard, a doorman, a ticket checker, etc., or with a device such asa turnstile. There may be fences to avoid circumventing this access control. An alternative of access control in the strict sense (physically controlling access itself) is a system of checking authorized presence, see e.g. Ticket controller (transportation). A variant is exit control, e.g. of a shop (checkout) or a country. In physical security, the term access control refers to the practice of restricting entrance to a property, a building, or a roomto authorized persons. Physical access control can be achieved by a human (a guard, bouncer, or receptionist), through mechanical means such as locks and keys, or through technological means such as access control systems like the Access control vestibule.Within these environments ,physical key management may also be employed as a means of further managing and monitoring access to mechanically keyed areas or accessto certain small assets . Physical access control is a matter of who , where, and when. An access control system determines who is allowed to enter or exit, where they are allowed to exit or enter, and when they are allowed to enter or exit. Historically this was partially accomplished through keys and locks. When a door is locked only someone with a key can enter through the door depending on how the lock is configured. Mechanical locks and keys do not allow restriction of the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed. Electronic access control uses computers to solve the limitations of mechanical locks and keys. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.When a credential is presented to a reader, the reader sends th e credential’s information, usually a number, to a control panel, a highly reliable processor. The control panel compares the credential's number to an access control list, grants or denies the presented request, and sends a transaction log to a database. When access is denied based on the access control list, the door remains locked. If there is a match between the credential and the access control list, the control panel operates a relay that in turn unlocks the door. The control panel also ignores a door open signal to prevent an alarm. Often the reader provides feedback, such as a flashing red LED for an access denied and a flashing green LED for an access granted .The above description illustrates a single factor transaction. Credentials can be passed around, thus subverting the access control list. For example, Alice has access rights to the server room but Bob does not. Alice either gives Bob her credential or Bob takes it; he now has access to the server room. To prevent this, two-factor authenticationcan be used. In a two factor transaction, thepresented credential and a second factor are needed for access to be granted; another factor can be a PIN, a second credential, operator intervention, or a biometric input.There are three types (factors) of authenticating information :▪something the user knows, ega password, pass-phrase or PIN▪something the user has, such as smart card▪something the user is, such as fingerprint, verified by biometric measurement.Passwords are a common means of verifying a user's identity before access is given to information systems. In addition, a fourth factor of authentication is now recognized: someone you know, where another person who knows you can provide a human element of authentication in situations where systems have been set up to allow for such scenarios. For example, a user may have their password, but have forgotten their smart card. In such a scenario, if the user is known to designated cohorts, the cohorts may provide their smart card and password in combination with the extant factor of the user in question and thus provide two factors for the user with missing credential, and three factors overall to allow access. Now, as people's living standards improve and technology advances, more and more local needs of access control system such as residential entrance, garage entrance, the entrance and other public places. Many different types of access control system; because it has different characteristics, so do not use the place, IC card access control system because of its higher security, better convenience and cost-effective access control system into the mainstream. IC card technology is currently widely used in various industries, particularly public transport, wireless communications, identification, financial transactions and security and defense industries. Access Control System software is easy to use, simple features, operators do not need a professional level of computer operation.。

中英文对照外文翻译(文档含英文原文和中文翻译)原文：Intelligent Entrance Guard SystemIntelligent entrance guard and safety management system is a new type of modern safety management system, which combines the microcomp uter automatic identification technology with the modern safety manag ement practices into an organic whole. It contains lots of new techno logies such as the electronic, mechanical, optical, computer technolo gy, communication technology, biotechnology, and so on. It is an effe ctive measures to achieve the goal of implementing safety management at the inward and outward of important departments. It can be applied to all kinds of confidential departments, such as banks, hotels, gen eratorrooms,the armory, confidential rooms, offices, intelligent commun ities, factories etc. With the rapid development of digital technolog y and network technology today, access control technology finally get s the good chance to develop rapidly. Entrance guard system has far t ranscends the pure doorway and key management.It has gradually develo ped into a set of complete access management system.1 The Development of Entrance Guard SystemInward and outward entrance guard system just as its name implies is a control system of managing the inward and outward channels, whi ch is developed on the basis of the traditional door lock. The tradit ional mechanical lock is just a simple mechanical device, so no matte r how reasonable the structural is designed, how strong the material is made, people can always open it through various means. Key managem ent is very troublesome in places like offices and hotel rooms where so many people entering and leaving the passageway. Whenever the keys are lost or employees are replaced, locks and keys must be renewed. In order to solve these problems, electronic card lock and electronic trick lock are invented. These two kinds locks’ appearance raised t he management level of inward and outward channels from a certain ext ent and has impelled the channel management to enter the electronics era. But with the continuous application of these two kinds of electr onic locks, the defects of themselves are gradually exposed. The prob lem of magnetic card lock is the easy replication of the information, a greater degree of wear between card and card reader, high failure rate and low safety factor. The problem of combination lock is that t he password is easy to leak and we do not have even any small clue to investigate with, so the safety coefficient is very low. At the same time, it is easy to be unlocked by people outdoor because most of th e reading card (password) and the control part is installed together outside the door at this period. Entrance guard system in this period have remained in its early immature stage, so the entrance guard sys tem is usuallyreferred to as electronic locks, which has not been widely applie d. With the development of inductive card technology and the biologic al recognition technology in recent years, the entrance guard system has got a leap-style development and has entered into the mature peri od. they have their special strong points in various aspects like saf ety, convenience, manageability, etc. The application fields of entra nce guard system is becoming more and more abroad.2 Function of Entrance Guard SystemBasic functions realized by mature entrance guard system: 2.1 The management of the channel access permissions.·Access permissions are set to formulate who can pass in and out each channel and who can't.· The way to pass in and out the channel means to scope out the a uthorization of the way to pass in and out to people who can pass in and out the channel. The ways to pass in and out includes entering pa ssword, reading the card(biometric), reading the card(biometric) plus entering password.· Access time means to set the range of tim e during which people who have the permission can pass in and out. 2.2 The function of real -time monitoringSystem administrators can keep a watchful eye on the situation ofpeople passing in and out of each gate region(there are photos as well at the same time) and the situation of each gate region(includi ng the door switch, warning in various kinds of abnormal conditions) through the microcomputer in real-time; they can also open and close all the door area in emergency conditions.2.3 Function of querying records of in and out:System can store all the in and out records, status. You can quer y the records and status according to different querying conditions. It is equippedwith corresponding attendance software so as to realize the purpo se of checking-in and guarding with one piece of card. 2.5 Function o f abnormal alarming:It can realize microcomputer alarm or alarm with siren in excepti onal cases, such as: illegal intrusion, not closing the door overtime, etc.It can also implement the following special features according to different entrance guard system:Fire alarm monitoring linkage function: The entrance guard system can automatically open all the locks to let the people inside to esc ape at any time in the event of a fire alarm.Automatic monitoring linkage commonly refers to the monitoring sy stem which will record the situation at that time and the warning con dition when someone charges (valid/invalid).Settings, managing and monitoring functions of the network : most of the entrance guard system can only use a microcomputer management, but advanced technology of the system can set, monitor, query and ma nage the whole system at any location which has been authorized in th e network. It also can set, manage, query and monitor in a different place through the INTERNET.Function of open the door logically: Simply put is that several p eople have to swipe the cards through the same door at the same time (or in other way) so that the electronic door lock will open. 3 Appli cations of Intelligent Entrance Guard System3.1 Application of Entrance Guard in The Work of The Companies in side The Intelligent Office Buildings:Doors installed with entrance guard on the door in the companies can effectively prevent the foreign salesman to disturb the order of office, and also can prevent foreign sundry to enter the company effe ctively , and then ensure the safety of the company property and thei r employees. You can display and improve the company's management lev el and improve the corporate image. Itcan also track whether the employees leave the company without ap propriate reasons. You can check on work attendance by using the atte ndance management software without buying time recorder. The results are more objective and fair and faster with higher accuracy rate. It can reduce the power and amount of work of personnel department. It c an effectively solve the problem that the employees have to change th e keys of the front gates due to fear. You can arrange the limites of authorities and door-open time flexibly. Workers just need to take o ne piece of card without adorning a large number of heavy keys and it is safer than keys.You can avoid the materials and documents in the leaders’ office been leaked by others and give the leaders a more secure and private environment by install entrance guard system on the door of the leade rs’ office. you can guarantee the core technology and data not been stolen easily by outsiders and prevent the employees of other departm ents from entering this department to disturb the developing work by installing entrance guard system in the development of technical depa rtment. You can guarantee the security of the property and the safety of the company's financial information by installing entrance guard system in financial department. You can prevent the other person from entering into the production workshop effectively and avoid causing safety problems by installing entrance guard system in the production workshop gate.3.2 Applications of in and out Management Control in The Intellig ent CommunityGenerally installed entrance guard system in the cell gates, elec tric gates, unit of steel fire doors, security doors can effectively stop other workers from entering into the community and conduct the c losed-end management in the community effectively. It can also change the old inaccurate and less rigorous management style of community s ecurities who distinguish whether he or she is an outsider just rely on their memory. If the new security guards stop the new residential, it will annoying them. If outsiders wear very well, the security gua rds will consider them the residential and let them in without any qu estion, which will bring potential safety hazard.The entrance guard s ystem of safety science and technology can improve the level of prope rty and it is better for developers to promote property. Owners will also benefit from the scientific and effective access of management. Networking entrance guard is advantageous to the security of monitori ng all the situation of in and out of the door at any time. If there are accidents or cases, it can provide evidence when the police later query the records.You can combine it with intercom system with visual intercom syst em. You can combine it with internal consumption IC card and parking management implementation into one card.3.3 Applications of Entrance Guard in The Government Offices:It can effectively standardize the order of office and prevent il legal personnel shocks to government offices, protecting personal saf ety of leaders. 3.4 The Application of Entrance Guard in Telecom Base Station and Substation Power Supply Bureau:Typical base station and substation power supply bureau has such characteristics: many base stations, big system capacity requirements, large distribution range or even hundreds of square kilometers. It h as its own network connected to the Internet. In some places it is ev en unattended, which needs the central dispatching room scheduling st aff flexibly at any time. Implementation scheme is to use the network entrance guard controller, to realize remote management through the LAN or the Internet. 3.5 Application of Entrance Guard in intelligent elevator control:It is also known as access control elevator, elevator card, IC ca rd elevator, which only authorized users can have the right to recall the elevator and choose hall according to the floor. More and more i ntelligent communities have been using relate equipments. The intelli gent control system of science and technology of Shenzhen has develop ed specially elevator control entranceguard control system form designing a proprietary elevator entran ce guard control system.中文译文：智能门禁系统智能门禁安全管理系统是新型现代化安全管理系统，它集微机自动识别技术和现代安全管理措施为一体，它涉及电子，机械，光学，计算机技术，通讯技术，生物技术等诸多新技术。

The equipment has the advantages of small size, single power supply and a variety of output voltage leads it has a special module. Through the analysis of the hardware structure, we can summarizes each module needs.For example,we often go through the keys to realize the control of the electronic device. Small to watch mobile phone, to the TV computer, to a variety of complex instruments, all need to realize various operations through the buttons. This design is an important part of step for the further research，using buttons to control the display，include some modules like LCD 1602 liquid crystal display，4*4 matrix keyboard，STC89C52single-chip microcomputer and other bine with the Proteus software，the simulation results are displayed on the LCD in 1602 type of data.KEY WORDS: Single-chip; LCD 1602 liquid crystal display; 4*4 Matrix keyboard31 IntroductionWith the development of economy and the progress of science and technology, Microprocessors and peripheral chips have developed rapidly. The newest development of the integrated technology is the CPU chip and external. Like the program memory, data memory, parallel, serial, I/O timing / counter, interrupt controller and other control components are integrated in a chip—single chip. SCM has a manufacturing process CMOS, The smaller lithography process improves integration which make the chip space smaller, lower cost, lower working voltage, lower power consumption. Adopts double CPU structure, increasing the width of data bus, improve the speed and the ability of data processing, a pipeline structure, improve the processing and computing speed, in order to meet the needs of real-time control and processing. To increase the storage capacity, the internal EPROM EPPROM, secure program, to improve the driving capability of parallel port, in order to reduce the peripheral driving chip, increase the logic function and control the external I/O port flexibility. Peripheral in serial mode based expansion; peripheral circuit internal installation is an obvious trend to connect the internet. Reliability and application level is getting higher and higher. Some high-end microcontroller and launched in recent years also contains many special function unit, Such as A/D4converter, modem, communication controller, PLL, DMA, floating point unit etc.So,as we add some external expansion of the circuit and channel interface it can constitute a variety of computer applications, such as industrial control systems, data acquisition system, automatic test system, intelligent instrument, intelligent interface, function module etc. With MCU development and complete structure,SCM has become a powerful tool and will have a higher level and broader development.2 Design of the whole structure of systemThis design is based on single-chip, include matrix keyboard and LCD display module. Single-chip is the first model to select the appropriate target, function, reliability, cost, accuracy and speed control system. According to the actual situation of the topic selection, configuration management model different mainly from the following two aspects: First, supply chain management has strong anti-interference ability; second, SCM has a higher price. For information input module, keyboard selection can use economic benefits and meet the requirements of the 4*4 key matrix keyboard can realize multi function key requirements. As for the output module, using LCD 1602 liquid crystal display module, liquid crystal to achieve key information processing functions after the show. The circuit of the system is required by AT89C51 chip, clock circuit, reset circuit, driving circuit, scanning line5driving circuit and LCD1602 LCD screen. 4*4 matrix keyboard accessof P1.0 —P1.7,LCD 1602 screen to access P0.0—P0.7.3 System hardware circuit design3.1 Liquid crystal moduleThe principle of liquid crystal display is the use of physical properties of liquid crystal, The display control area voltage, power is displayed, it can display graphics. Liquid crystal display with thin thickness, suitable for large scale integrated circuit directly driven, easy to realize full color display characteristics, has been widely used in many fields of portable computer, digital camera, PDA mobile communication tools etc.1602 liquid crystal is also called the 1602 character LCD, which is a special used to display letters, numbers, symbols of the LCD module. It is composed of a plurality of 5X7 or 5X11 dot matrix character components, each dot matrix character who can display a character, there is a distance between the interval of each, there are intervals between each line, played the character spacing and row spacing, and because of this it is not well display graphics (with custom CGRAM, show the effect is not good). 1602 LCD refers to the display of the content for the 16X2, which can display two lines, 16 characters per line (LCD moduledisplay characters and numbers).63.2 Matrix keyboard module1. Key characteristicsThe keyboard is composed of a number of separate keys, press and release key is through the closed mechanical contact and off to achieve, because of the elastic action of mechanical contact, in the closing and the opening of the moment has a dither. Jitter must be eliminated, include software and hardware elimination.2．Scanning principleFirst determine whether a key is closed, and then one by one scan to further determine which button closure;(1) D0 ~ D3 output 0, level detection line D4 to D7. If the D4 - level D7 all high, said no key was pressed. If the D4 - level D7 is not all high, said the key was pressed.(2) If no key closure, return the scanning. If there is a button closure, in column by column scanning, closed key key number to find out. The D0=0, D1 ~ D3=1, D4 ~ D7 level, if D4=0, said the K1 key is pressed; similarly, if the D5 ~ D7=0, K5 respectively, K9, K13 key is down; if the D4 ~ D7=1, said that without a key is pressed. Then the D1=0, D0, D2, D3 was 1, the scanning of the second columns, which were carried on, until the closure of the key found.4 Software design7The software design mainly consists of keyboard scanning procedures, write instruction code program of LCD module, LCD module display data initialization code written subroutine, liquid crystal display module, liquid crystal display a character subroutine, time delay subroutine and so on. Programming for each module, software programming ended, Keil software was used for debugging, when the various parts of the program debugging is correct, according to the source sequence of calls, the parts together, compile, compile successfully downloaded to the mcu. The result is when the user presses a key, LCD display of the button is pressed after the realization of functional parameters corresponding to the. When the system power supply, P1 port scan cycle and the key button debounce, after completion of input through the SCM processing, output in the P0 port, through the liquid crystal display program content, complete system function.5 ConclusionWith the continuous development of high and new technology, the miniaturization and the miniaturization of electronic products has been achieved. And all kinds of new technology, as a single field of the new method, the development trend of new products and symbol -- intelligent significantly is one of the trends in development. The module design display microcontroller matrix keyboard and LCD, make us understand8to this technology innovation, through in-depth study on this technology, we can master the use in other areas, such as the design of electronic password lock, adjustment and control of indoor temperature and humidity, field access control system design etc.. Technological progress and economic development are the main themes of the present era, the improvement of people's living standard is bound to the requirements of electronic products increase, the design of any a small system is for a foundation, design of system innovation, the hardware, software integration, method and technology of virtual display and soft measurement artificial intelligence, I firmly believe that our life will be more colourful.9基于单片机的矩阵键盘与液晶显示的设计摘要微电子技术的发展和工业测量的需求，给系统的开发及深入研究带来了良好的契机，发展前景广阔。

System Design.The intelligent door lock system is designed to authenticate users based on their voices and grant accessto the locked area. The system consists of hardware and software components. The hardware components include a microcontroller, a gating circuit, an extended memory, anda voice input/output circuit. The software components comprise voice training, voice recognition, voice data processing, and a voice-activated control module.The microcontroller serves as the brain of the system, controlling and coordinating all other components. It receives voice input from the user, processes it through the voice recognition module, and compares it with the pre-stored voice templates stored in the extended memory. If the match is successful, the gating circuit is activated, unlocking the door.III. Hardware Selection.In this system, the microcontroller plays a crucial role. We have chosen the SPCE061A single-chip microcontroller due to its excellent performance, low cost, and ease of programming. The gating circuit is designed to control the locking mechanism of the door. The SPR4096 extended memory is used to store the voice templates and other important data. The voice input/output circuit is responsible for capturing the user's voice and generatingthe necessary audio output.IV. Software Development.The software development process involves writing code for the voice training module, voice recognition module, voice data processing module, and voice-activated control module. The voice training module allows users to record their voices and create voice templates. The voice recognition module compares the user's voice input with the pre-stored voice templates and determines whether the match is successful. The voice data processing module handles the preprocessing and feature extraction of the voice signal. The voice-activated control module controls the gating circuit and unlocks the door if the voice recognition is successful.V. Testing and Evaluation.To evaluate the performance of the intelligent door lock system, we conducted rigorous testing. The testing included testing the accuracy of voice recognition, theresponse time of the system, and the durability of the hardware components. The results obtained from the testing indicate that the system is reliable, accurate, and user-friendly.VI.

智慧门禁系统英文设计方案Design Proposal for an Intelligent AccessControl System1. IntroductionAn intelligent access control system is a sophisticated security system that uses advanced technology to control access to buildings orspecific areas within buildings. This systemprovides enhanced security by allowing only authorized individuals to enter restricted areas. This design proposal presents an overview of an intelligent access control system, its components, and its benefits.2. System ComponentsThe intelligent access control system consistsof the following components:2.1 Access TokensAccess tokens are provided to authorized individuals and grant them access to specific areas. These tokens can be in the form of access cards,key fobs, or biometric information such as fingerprints or facial recognition.2.2 Card ReadersCard readers are installed at access points and require users to present their access tokens. These readers communicate with the central system to verify the authorization of the individual and grant or deny access accordingly.2.3 Central SystemThe central system manages and controls the access control system. It houses the database of authorized users and their access permissions. It communicates with the card readers to verify access requests in real-time and logs access events for auditing purposes.2.4 Monitoring StationThe monitoring station provides a centralized view of the access control system. Security personnel can monitor access events in real-time and respond to any security breaches or anomalies.3. System FunctionalityThe intelligent access control system operates as follows:3.1 Access RequestWhen an individual approaches an access point, they present their access token to the card reader.The reader sends the token information to the central system for verification.3.2 Authorization VerificationThe central system checks the access token against the authorized users' database and verifies the individual's access permissions. If the individual is authorized to access the requested area, the central system grants access and sends a signal to the card reader to open the door.3.3 Real-time MonitoringThe monitoring station receives real-time updates on access events. Security personnel can monitor access attempts, identify unauthorized individuals, and take appropriate actions in case of security breaches.3.4 Logging and ReportingThe central system logs all access events, including successful and unsuccessful attempts. This information is used for auditing purposes and generating activity reports.4. Benefits of an Intelligent Access Control SystemImplementing an intelligent access control system provides several benefits:4.1 Enhanced SecurityBy allowing only authorized individuals to access restricted areas, the system significantly enhances security and prevents unauthorized access.4.2 Improved Access ManagementThe centralized system simplifies access management by providing a single point of control. Administrators can easily add or remove users, modify access permissions, and monitor access events.4.3 Real-time Monitoring and AlertsThe monitoring station provides real-time updates on access events, allowing security personnel to respond promptly to any security breaches. The system can also generate alerts in case of unusual access patterns or suspicious activities.4.4 Auditing and ReportingThe system logs all access events, providing a detailed audit trail. Activity reports can be generated to track access patterns, identify potential security gaps, and comply with regulatory requirements.5. ConclusionAn intelligent access control system is acrucial component of modern security infrastructure. By utilizing advanced technology, such as access tokens, card readers, and a centralized system,this system provides enhanced security, improved access management, real-time monitoring, and comprehensive auditing capabilities. Implementing such a system ensures the protection of valuable assets and enhances the safety of individualswithin a building or restricted area.。
