The objective of this project is to create a reliable and efficient fire detection system that can quickly identify and alert individuals about potential fire hazards. The designed circuit utilizes various sensors, control components, and signal processing techniques to achieve its objectives.Design ConsiderationsThe fire alarm system design takes into consideration several key factors such as accuracy, reliability, response time, and ease of operation. These considerations ensure that the circuit not only effectively detects fires but also minimizes false alarms. Additionally, the circuit should be capable of promptly notifying relevant authorities or individuals nearby.Sensor SelectionTo accurately detect fires and smoke, we have chosen two commonly used sensors: smoke detectors and heat detectors. The combination of these sensors enhances the system's ability to promptly sense any early signs of a fire in different conditions.Smoke DetectorsSmoke detectors utilize optical or ionization principles to detect smoke particles suspended in the air. For this project, we have selected an optical smoke detector due to its effectiveness in detecting visible smoke particles. When smoke enters the optical chamber, it scatters light onto a photocell sensor connected to the control circuit. This change in light intensity triggers the alarm signal.Heat DetectorsHeat detectors are designed to trigger an alarm when there is a significant increase in temperature within their vicinity. Two types of heat detectors are commonly used: fixed temperature heat detectors and rate-of-rise heat detectors. For our project, we will employ a fixed temperature heat detector since it provides reliable detection by triggering an alarm when a preset temperature threshold is exceeded.Control Circuitry DesignThe control circuit plays a vital role in processing signals from both the smoke detector and heat detector while ensuring proper functioning and integration with other relevant components.Signal ProcessingUpon receiving signals from either sensor indicating the presence of fire or excess heat, the control circuit triggers the alarm system. It also monitors the overall status of the circuit, including power supply stability and sensor functionality.Alarm SystemThe alarm system should provide a clear and loud signal to indicate the presence of fire. We have selected a combination of audio alarms, such as sirens or buzzers, and visual indicators, like flashing lights or LED displays.Power SupplyA stable power supply is crucial for uninterrupted operation of the fire alarm circuit. For this project, we will use a backup battery combined with an AC-to-DC converter. The backup battery ensures that the system remains active during power outages.ConclusionIn conclusion, this report has presented the design and implementation aspects of a fire alarm circuit for an electrical engineering course project. The chosen sensors, control components, and signal processing techniques work together seamlessly to accurately detect fires and excess heat. By considering factors such as accuracy, reliability, responsetime, and ease of operation throughout the design process, we have produced an effective fire detection system that minimizes false alarms while ensuring prompt alerts to relevant authorities or individuals nearby.。

The system consists of a microphone, an analog-to-digital converter (ADC), a 16x2 LCD display, and the 51 microcontroller. The system is capable of measuring the intensity of noise and displaying the results on the LCD display in decibels.Hardware DesignThe hardware design of the noise detection system is relatively simple and consists of four main components: a microphone, an ADC, an LCD display, and the 51 microcontroller. The microphone is used to detect sound waves in the environment and convert them into analog signals, which are then amplified by a preamplifier and fed into the ADC. The ADC converts the analog signals into digital signals that can be processed by the microcontroller. The microcontroller uses a program to process the digital signals and display the results on the LCD display.The microphone used in the system is a condenser microphone, which is highly sensitive to sound pressure and has a wide frequency response range. The preamplifier is an operational amplifier (OP-AMP) circuit that amplifies the analog signals from the microphone and provides a stable and accurate output to the ADC. The ADC used in the system is an 8-bit resolution ADC with a sampling rate of 10 kHz. The LCD display is a 16x2 character display that displays the noise level in decibels.Software DesignThe software design of the noise detection systemincludes the program that runs on the 51 microcontroller. The program is written in C language and is divided into several modules, including initialization, ADC, LCD, and main modules. The initialization module initializes the ports andperipherals of the microcontroller. The ADC module configures the ADC and reads the digital signals from the microphone.The LCD module displays the results on the LCD display. The main module contains the main program loop that continuously reads the noise level and updates the LCD display.The program uses a calibration factor to convert the digital signals from the ADC into decibel values. The calibration factor is determined by measuring the noise level of a known sound source, such as a reference tone, and comparing it to the output of the system. Once thecalibration factor is determined, the program uses a logarithmic function to convert the digital signals into decibels.Experimental ResultsThe performance of the noise detection system was evaluated through a series of experiments. The system was tested in several different environments, including a quiet room, a noisy industrial workshop, and a busy city street.The noise levels were measured using a professional soundlevel meter, and the results were compared to the outputs of the system.The results showed that the noise detection system was able to accurately measure noise levels in all environments, with a maximum deviation of 1 dB compared to the sound level meter. The system was also able to provide real-time feedback on the intensity of noise levels, making it easy to identify and monitor changes in noise levels over time.ConclusionIn this paper, we have described the design and implementation of a noise detection system based on the 51 single-chip microcontroller. The system is simple, low-cost, and portable, making it suitable for a wide range of applications, including industrial noise monitoring, environmental noise monitoring, and personal noise exposure monitoring. The hardware and software components of the system were described, and the system's performance was evaluated through a series of experiments. The results showed that the system was able to accurately measure noise levels and provide real-time feedback on the intensity of noise levels in decibels.。

Curriculum ideology and politics refers to the organic integration of ideological and politicaleducation content into the curriculum to help students establish a correct outlook on life and feelings of family andcountry. It is an important measure for college education, which not only responds to the call of the country, but alsopromotes the shaping of students ’ personality and all-round development. This paper takes the Practical English inInteraction course of the University of Shanghai for Science and Technology as an example to explore the applicationof curriculum ideology and politics, so as to better exert the educational value of College English courses.Keywords: College English, Practical English in Interaction, ideological and political teaching, course designIntroductionThe Practical English in Interaction course of the University of Shanghai for Science and Technology is an interactive comprehensive English course. Guided by foreign language teaching theories, it adopts a combination of online and offline teaching form, integrates various teaching modes and methods, aims to expand English language knowledge and improve students ’ English practical skills, and emphasizes the practicability of the language and the interactivity in the teaching process. It aims to cultivate students ’ comprehensive English application ability, especially their interactive ability in reading, writing, listening, and critical thinking, so that they can effectively communicate written and oral information in English in their future study, work, and social interaction.According to the guideline issued by the Ministry of Education of China in June 2020, which requires all colleges and universities in China to fully implement ideological and political education and improve the quality of talent training, this course has a unique innate advantage of ideological and political education because it covers all students learning College English courses. After the concept of ideology and politics was proposed, English teachers, as the guide and organizer of the class, combining with China ’s national conditions, integrated ideological and political elements into the online and offline resources in teaching. With all these teaching methods, they broaden students ’ scope of knowledge, guide them to further understand Chinese and Western JIN Zhao-hui, M.A., lecturer, College of Foreign Languages, University of Shanghai for Science and Technology, Shanghai, China. D A VID PUBLISHINGDTAKING PRACTICAL ENGLISH IN INTERACTION AS AN EXAMPLE275cultures, improve their comprehensive cultural literacy, and cultivate their outlook on life and the world, thus meeting the needs of economic development and international exchanges, and contributing to the implementation of the fundamental task of establishing virtues and educating people.Overall Design Principles for the Practical English in Interaction CourseWith Curriculum Ideology and PoliticsCultivating Morality and Educating People“Curriculum ideology and politics” refers to a comprehensive educational concept that combines various courses with ideological and political theory in the form of constructing a whole-course education pattern, generating a synergistic effect, and taking “cultivating morality and educating people” as the fundamental task of education. Therefore, “moral cultivation” is the first principle we should follow in the design of ideological and political teaching. The purpose and significance of ideological and political education of College English courses is to cultivate students’comprehensive English application ability, improve their own political accomplishment, help them understand themselves correctly, so as to meet the needs of social development and international exchanges, and become international talents with high moral character and clear political stance. Natural IntegrationThe nature of humanities and teachers’ sense of mission of “preaching, teaching and solving doubts” have made College English teachers integrate ideological and political elements and feelings of family and country into their classes before the concept of ideological and political curriculum came into being. After the concept was proposed, teachers more consciously integrated elements such as national policies and education directions into the supporting textbooks in the process of teaching. In the training process of listening, speaking, reading, writing, and translating, they imperceptibly shaped students’ personality and cultivated their views and values, achieving a natural integration and all teaching effects.Classroom PracticeThis course, with New Century College English (Second Edition) Zooming in: An Integrated English Course 3 as the teaching material, is based on the form of classroom discussion, independent learning and practice after class. The content of the textbook covers such topics as interpersonal relationship, love, friendship, sports, health, happiness, education, and cross-cultural communication, which can play a positive role in guiding college students to shape their outlook on life and world. In the process of teaching, teachers supplement materials with Chinese characteristics and ideological and political elements, which will help students understand the current world with a broader vision in combination with domestic and foreign conditions. For example, in the third unit “What Is Friendship?”, by integrating ideological and political elements into several sections, such as background information introduction, text analysis, and translation practice, teachers help students understand ancient Chinese culture, establish a correct concept of making friends, have a general understanding of China’s “Belt and Road” initiative, and cultivate national pride as well as an overall perspective toward the world.Background Information IntroductionThis section focuses on two famous friendships, namely between Yu Boya and Zhong Ziqi in the Spring and Autumn Period in ancient China and Marx and Engels in modern Germany. Yu Boya was a musician andTAKING PRACTICAL ENGLISH IN INTERACTION AS AN EXAMPLE276good at playing the Chinese Guqin (a Chinese musical instrument). Zhong Ziqi was a woodcutter wearing a bamboo hat, with an axe on his back. Ziqi once heard Boya playing the Guqin in a mountain, and could even understand his music and feelings. With the teacher’s explanation of the friendship between Boya and Ziqi, students acquire deeper knowledge of the origin of ancient Chinese idioms, such as “伯牙鼓琴而六马仰秣(Boya played the Guqin so amazingly that the horses even listened attentively and ignored the feed)”, “知音(bosom friend)”, “高山流水(high mountain and flowing water)”, and “伯牙绝弦(Boya broke the strings)”, and feel the traditional Chinese culture, thus recognizing that true friendship transcends the classes, bridges the social gap, and reaches the fit of two hearts. With the knowledge of the friendship between Marx and Engels, students realize that a true friend is one who stands with his friend all the way and will selflessly help his friend no matter what his situation is. So that students can come to the conclusion that the true friendship is the tacit communication of two souls regardless of fortune or social ranks.After learning about these two sincere friendships, the teacher raises the question: “While friendship is necessary between people, is it the same between countries?”The answer, of course, is yes. The peace and prosperity of the world requires the participation of every country, and China’s Belt and Road Initiative is put forward in this context. Through the teacher’s introduction and illustration of the “Belt and Road” initiative, students expand their vocabulary, know the concepts of “Silk Road Economic Belt” and “21st Century Maritime Silk Road”, and understand the background of the initiative and the need to build friendship with countries along the Belt and Road and the economic benefits that come along with it.Text AnalysisIn the section of text analysis, students have read through the full text online before class, completed the preview questions assigned by the teacher, and had a certain understanding of the content of the article. The teacher puts forward the questions, “What is friendship?”, “What functions and influences should friends have on each other?” After group discussion and exploration of the questions, in light of the viewpoints of Aristotle and Cicero in the text and the background knowledge, the conclusion is drawn that friendship should transcend material interests and pleasure, and come from people’s sincere emotions generated by their inner desire for beautiful things and contributions to the common good, thus establishing a correct view of making friends in students. To guide students to further deepen their understanding of friendship, the teacher continues with the questions “What do you and your friends often do together?”, “If your friend did something wrong, would you help him hide it?” Students organize discussions and believe that real friends together are far more than simple playmates, but should help and supervise each other, grow and make progress together, and contribute their wisdom and strength to the correct and public cause, so as to forge true friendship. Students can reflect on some of their own and their friends’ behaviors and set higher life goals.Exercise After ReadingIn the exercise part after the text analysis, the teacher explains in detail the translation skills of Chinese sentences without a subject. By comparing the differences in thinking mode between Chinese and English, the difficulty in the translation of subjects is found. On the whole, Chinese emphasizes integrity and intuitiveness, and is a paratactic language with simple and flexible language structure, so sentences are loose and open, with a structure not so obvious. There are often some non-subject sentences. However, English emphasizesTAKING PRACTICAL ENGLISH IN INTERACTION AS AN EXAMPLE277individuality and analysis. English is a hypothetic language with diverse and rigorous language combinations. Generally speaking, English sentences must have subjects. For instance, when the Chinese sentence “起风了，下雨了” is translated into English, the subject should be added: It is blowing and raining. By comparing the structure of the sentence in Chinese and English, students become interested in exploring the differences between the two languages. Another example is the Chinese proverb “留得青山在，不怕没柴烧(Where there is life, there is hope)”. Adding the structure “there be” fills students with enthusiasm to explore the English version for Chinese idioms and proverbs. In addition to the translation of commonly used expressions in daily life, teachers also include current affairs and government work reports in the exercises, such as “积极推行政府法律顾问制度，深入推进政务公开(We will actively promote the system of government legal advisers and make government affairs more open)”. While training translation skills, students can compare Chinese and English grammatical structures, understand the two cultures, get familiar with national policies, and cultivate national emotions.In the teaching of other units, teachers have included the comparison of Chinese and English languages, as well as the introduction and explanation of Chinese and Western cultures and national conditions in each teaching plate. For example, in the eighth unit of intercultural communication, the teacher starts with the introduction of Chinese and Western social etiquette and ways of thinking, and gradually guides the students to think about the root causes of culture shock and how to deal with it. Students realize that culture shock comes from a lack of understanding of the other’s culture, instead of hostility to it, so as to maintain cultural confidence and cultural tolerance.ConclusionThe goal of College English teaching is to cultivate students’ English application ability, enhance their cross-cultural communication awareness, develop their self-learning ability, improve their comprehensive cultural accomplishment, and cultivate their humanistic spirit and critical thinking. In the new era, the fundamental question of education is “who to train, how to train people, and for whom to train people”. In the teaching process of Practical English in Interaction course, the thought of ideology and politics is integrated, and the combination of English language, culture, customs, and other factors makes this course not only a window for students to gain insight into foreign culture, but also an important position for carrying forward Chinese traditional culture, stimulating national pride, and cultivating students’feelings of home and country. By the joint efforts and presentation of teachers, teaching materials, and students, we can achieve the effect of collaborative education and cultivate new century talents who develop deep affection for the motherland and have an international vision.ReferencesChen, M.

uCOS文件系统Document system design based on uC/os-iiDocument system design based on uC/os-iiAbstract: this paper presents the design and implementation of a file system based on mu C/os-ii. Through the analysis on the file system hierarchy structure and functional modules, gives a detailed design scheme of the file system, including file control block, file descriptors and protection mechanism, etc. Finally, the paper expounds the technology of the file system to guarantee reliability.Keywords: real-time embedded system mu C/os-ii file system1 introductionFrom the point of view of system, a file system to store files for storage space organization, allocation, information transmission, and the stored information retrieval and protection, etc.; From the user's point of view, the file system should be convenient for accessing the file, the information storage is safe and reliable, it can be Shared and it can be kept secret. When the user requires the file system to save a dead file, the file system can place them in place. When a user wants to use a file, the file system can find a specific file based on the file name.File system design, must follow the following basic principles: the first conciseness, relatively perfect in the existing file system fully functional, high requirement of system resources,and we need the embedded file system is a middleware, embedded platform for concise and highly efficient and reliable. For this, we in the design process using the ms-dos FAT16 file system format form of directory for file management, open the file data structure is adopted similar to the UNIX system file table, for every open file pointer FS_FILE, set up a data structure allows the user interface is simple and clear. Second device driver support (multi media compatible), considering the application of the generalized and the diversity of the storage medium, for we must consider when design file system compatibility of a variety of storage media. The whole system adopts modular layered design principle and the realization of object oriented method, makes the users can easily at the top of unified application interface to a variety of storage media file operations. Using this file system, you can manage different storage mediums and access different hardware at the same time. Third operating system support, file system development is based on mu C/OS - II, in the process of design and development, after considering the support for multiple operating systems, OS interface module design for the dynamic variable, when the file system is applied to other operating systems, just put the OS operating system information in the interface module will turn to the new operating system. The fourth reliability, due to the importance of data resources of the embedded system, require physical media stored data must have high stability, but we know that some people or external factors may cause the damage of the medium, resulting in the lack of data, so we're going to maximize the file system reliability.The hierarchy and function modules of the file systemDue to the function and role of the embedded file system is different from ordinary desktop operating system file system, led to the two on the architecture of great differences. In ordinary desktop operating system, file system is not only to manage files, provide file system calls the API, and manage various equipment and support to the equipment and the consistency of the file operations (i.e., to like operating files to operate all the I/O devices). This rule has changed a lot in embedded file systems. In some cases, embedded Systems can be customized for special purpose, especially as ASOS (Application Specific Operating Systems, Application for customized embedded Operating system), the development of the embedded Operating system of the regularity of the system function, scalability and flexibility in higher requirements are put forward.Based on these considerations, we adopted the embedded file system architecture shown in figure 1,The file system defined by this structure has three levels from top to bottom: the first layer is the API layer, the second layer is the intermediate layer, and the lower layer is the dielectric drive layer. The first API layer, API layer is the file system and the interface between user applications, it has a standard C library, which contains such as open files (FS_FOPEN), write documents (FS_FWRITE), and other functions. The capability of this layer is to transfer user calls to the intermediate layer. This is the core of the whole system design, and only the visible part of the embedded file system users - the POSIX standard file system in the system call all be realized in this part. Themiddle layer transition layer is the foundation for the structural integrity of the file system to provide the hardware independent interface for the implementation of the file system. Intermediate transformation layer contains a file system layer and logical pieces, including sub-layer will explain file operations, file system into logical pieces, then the file system calls logical pieces layer according to the definition of different equipment and the corresponding device driver; The logical block sublayer is primarily a synchronous access to device drivers, providing a friendly interface. Dielectric drive layer: the dielectric drive layer is the minimum program that accesses the hardware, which is structured to facilitate access to the hardware. The function of this layer is to complete the access to the media. The important task of this layer is to provide a unified device driver interface.According to the hierarchical structure of the file system, the file system can be divided into four big functions: API interface module, intermediate conversion module, disk partition module, device driver module. The API interface module mainly completes the basic operation of the file, including the generated, deleted, open, closed, file read, file write, etc. The intermediate transformation module mainly completes the inspection of access rights, the choice of media, the logic to the physical transformation. Disk partition module is mainly to complete the initialization of a few key data structures, information, and the file system's overall partitions each partition of several parts: the free management, boot sector, FAT area, file storage area, etc. Complete storage medium driver device driver module, containing a driver function table and medium read, write, check status, performspecific command driver.Detailed design of the file system3.1 file system organizationThe file system logic organization is a streaming file, and the physical organization is a continuous file. The user's access to streaming files is in bytes. The interior of each file has a read/write pointer, through the system call the pointer can be fixed to a certain location of the document, read and write system calls will start as determined the location of the pointer. The physical device used to save the file is divided into block pages, and the physical structure of the file is to determine how the bytes are stored in the storage medium. So said documents physical organization form for the performance of the file system has a more direct influence, so we in the file when the physical organization of choice more carefully. Combined with the practical application of our system, we decided to file a physical organization structure of the order, it's because our embedded applications require high real-time performance, once the data collected in the form of file stored in the medium changes little, which is the length of the file a little change, so we will be the logical file information stored in CRT numbered consecutively physical block.3.2 files and file control block FCBIn order to achieve the management, the File system need to acquire a set of relevant documents information, for example, the File's name, address, date of the establishment of the File,and so on, these information together constitute a data structure, here is what we call the File Control Block FCB (the File Control Block). The FCB is a symbol of the existence of a file, which records all the information that the system needs to manage the file, as shown in figure 2. Each file has a file control block, which is saved in the outer space,If you find a wrong FAT table, you will use the correct FAT table to overwrite the error. If the main FAT table is wrong, and there is a correct backup FAT table, the main FAT table is covered with the backup FAT table; If the main FAT table is not correct and the backup FAT table is incorrect, the FAT table crashes. You can only repartition at this point.In addition, because the service life of the storage medium is limited, so we in the design of the file system has been in line with the principle of as little as possible of the medium directly, speaking, reading and writing. The specific approach is to set up a map of the FAT table in memory and read the FAT table into memory when the file system starts. In this way, if the changes to the FAT table are involved in the upper operation, it is typically done in the memory FAT table map without the operation of the medium. Us by setting an updated logo to determine time, for the first time the FAT table within the storage medium into memory initialization when the flag is false, once the operation has generated a new file or release blocks and need to modify the FAT table entries, namely the flag is true. At the same time we set a timer to determine the time of update the FAT tables on the media, at regular intervals to verify the update timer logo, if the flag is true the converts FAT FAT table table writing medium. Of course, the above testupdate will be performed whenever the timer is turned off. With this design, we can greatly reduce the number of updates to the FAT table on the storage medium, and also achieve the purpose of the service life of the device.Due to the life of the storage medium problems, with the increase of the growth of the time and the use of number, separate areas there will be a file to read error, so we in the design of the file system is also considered bad in inspection and management. The way to test whether a particular page damage is: writing data to a page immediately after reading, if inconsistent data read and write, shows the page to bad page. For inspection to bad pages, are marked in the free administrative zone, later don't allocate these bad page storage area distribution, that is the bad page is removed from the free blocks, as long as no bad page to read and write operations, the file system will not appear any problems.To ensure the reliability of the FAT table, the check and mechanism was introduced. Similarly, when we design the file system, we can improve the reliability of the data by setting the checksum in a community section. The last four bytes of each page are the checksum for the page, and the value of the checksum is the cumulative value of the data on this page. The checksum is recalculated at the same time as the data is changed. If abnormal shutdown, such as an accident case, the boot after operation on the next to the page may be retained by comparing the checksum with the sum calculated checksum to check whether the page data error.5, the conclusionEmbedded system development is a trend of post-pc era, all kinds of embedded operating system is also struggling for the possession of a piece of space, open source code, this feature is doomed mu C/OS - II is very suitable for embedded systems. Open source has led to a custom is convenient, the developer can extract essence, from multiple software applications to their own applications, thus greatly save development cost, shorten the development cycle. In this paper, the file system is designed using the characteristics of the mu C/OS - II, do a more efficient, convenient, easy to maintain, easy to transplant, and the system resources occupancy rate low, fully embodies the characteristics of the embedded middleware, the use of great convenience to the user.References:1 JEAN j.abrosse, a real-time embedded operating system with open source code for the open source code of China power pressWang tian miao with embedded system design and the example development tsinghua university press 2002.09Meng qingchang, the author of the tutorial on the operating system, is an example of UNIXShen, xuansheng, 2001, 2001, 2001, 2001.10。
