The purpose of this specification is to ensure a clear understanding of the requirements, architecture, and implementation details among the development team, stakeholders, and other interested parties.2. System OverviewThe embedded software system is designed to power a smart sensor node for environmental monitoring. It collects data such as temperature, humidity, and pressure from various sensors and transmits it wirelessly to a central server for analysis and storage.3. Software RequirementsFunctional Requirements:Collect data from sensors accurately.Transmit data wirelessly to the central server.Have the ability to configure sensor settings remotely.Non-functional Requirements:Low power consumption.High data transmission reliability.Secure communication.4. System ArchitectureThe embedded software system consists of three main components: sensor interface module, communication module, and control module.Sensor Interface Module: Responsible for interacting with the physical sensors, acquiring data, and preprocessing it.Communication Module: Handles wireless data transmission to the central server using a suitable communication protocol.Control Module: Manages the operation of the system, coordinates data flow between modules, and implements remote configuration functionality.5. Software DesignModule Interaction: Modules will communicate with each other using inter-module messages and shared memory segments.Data Structures: Defined data structures will be used to efficiently store and transmit sensor data.Algorithms: Algorithms for data preprocessing and wireless transmission will be optimized for speed and efficiency.6. Implementation DetailsProgramming Language: The system will be implemented using C/C++ for its efficiency and portability.Hardware Considerations: The software design will take into account the limitations and capabilities of the target hardware platform.Testing: Rigorous testing including unit testing, integration testing, and system testing will be conducted to ensure the software meets the specified requirements.7. ConclusionThis design specification outlines the requirements, architecture, and implementation details for the development of an embedded software system for environmental monitoring.

Self-introduction 1 Good morning! Professors:I’m very glad to be here for this interview, and I hope I can make a good performance today.My name is SuYing, I come from college of public administration of Hunan Normal university. My major is politics science and administration, the major for father education that I pursue here is politic theory.I like my major very much. And I have got top scores in our grand. During the past three years, I studied political science, administrative science, international politics, and law. I possess such abilities below: political research, public policy analysis, social surveys and statistics. During my university life, I once designed a questionnaire on youth volunteer in universities of Hunan, and wrote a report, which got the second award of my college this year. I did an investigation on commerce of village in the city, the survey report of which has been published. The study in my major also gave me a macro, rational thinking habit, and a more professional perspective on social problems, because of which, I have written 100,000 words on my blog, which has got 25 articles published in the internet ,books or newspapers.About practice, I am always proud as a youth volunteer. I was a head of the youth volunteer association of my college. During the university time, I organized and participated nearly 30 activities. In addition, this summer I worked in a community for about 1 month. Thanks to those experiences, I used my knowledge in real affairs and increased my abilities in realated aspects.Recently, I am interested in political communication and political culture. If I can be a postgraduate of china politics and Law University, I hope I can do specific and deep study on those aspects.That’s all. Thanks for your attentio ns.Self-introduction 2My name is SuYing, I come from college of public administration of Hunan Normal university.

THANK YOU FOR YOURATTENTION！第二篇：Good morning. I am very glad to be here for this interview.2.姓名，英文名，毕业院校，毕业专业，毕业学院First let me introduce myself. My name is LiShuai, and my English name is Jacky Lee. I've finished my undergraduate education in Xidian University, Majoring in Electronic Science and Technology in the college of Technical Physics.3.性格，爱好，实践经验I am open-minded, willing and have broad interests like basketball, reading and especially in engineering such as software programming, website design, hardware design. For example, during the past four years, I have accomplished two websites: one is the website of our school, and the other is the website of the doctor forum of china 2007. Furthermore, I am interested in C plus plus programming language and have written some application programs. In July in the last year,I finished my graduate project with flying colors,which was a software application about Image Process . In addition, I have also finished some projects about embedded system by using MCU when I was a junior.4.为什么想读研,将来愿意从事的方向,读研时的打算Although I have broad interests in many aspects and grasp the essential knowledge of the major, but I think at present, I can do many things in a superficial level, but not be competent to do things professionally owing to lack of ample knowledge and ability.So I think further study is still urgent for me to realize self-value.The major that I hope pursue for my further education is IC design. Because I find integrated circuits are playing a more and more important role in our modern society. And nowadays in China, with the recognition by the government, our domestic integrated circuits industry is growing rapidly and that may provide a lot of chances to us.I plan to concentrate on study and research in this field in my graduate time. And I hope I can form a systematic view of micro electronics and IC design technology and make a solid foundation for future profession after three years study here.5.结束语OK, that’s all.
