Design And Implementation Of Check In System For Extracurricular Physical Exercise Based On Rfid And UDP Protocol

With the development of Internet of Things technology,it has brought new opportunities for more comprehensive campus information management.Extracurricular physical exercise for school students is one of the important aspects of school activities.In order to enrich the campus information management methods and promote more comprehensive campus information management,aiming at the comprehensive management needs of school students for extracurricular physical exercise,the development method of the school students' extracurricular physical exercise check in system is researched in this thesis.Making full use of the campus information base network,we research and implement the extracurricular physical exercise check-in system in which the check-in site is based on C/S and check-in center management software is based on B/S.The main research work of this thesis is as follows:Firstly,the functional requirements,technical requirements and non-functional requirements of the extracurricular physical exercise check-in system are analyzed.The system should have core modules such as identification,event monitoring,alarm processing,data management and user management,and develop from the system.The technical feasibility,economic feasibility and operational feasibility of the implementation are analyzed to lay the foundation for the design and implementation of the system.Secondly,aiming at the real-time and reliability requirements of data transmission in the extracurricular physical exercise check-in system,a handshake algorithm based on UDP protocol for reliable data transmission between the RFID reader and the check-in server is proposed to ensure that the card device reliably transmits the received check-in information to the check-in server,and the data transfer protocol is simple and easy to implement.The protocol is suitable for data transmission of the extracurricular physical exercise check-in system.Thirdly,the entire development architecture of the system,the check-in information acquisition in RFID site,the system database,etc are comprehensively designed,including the timing diagram of the system development function module,ER diagram for the database.Meamwhile,the communication security and data security for the system are also designed.Fourthly,according to the system design scheme,the system coding is realized by using Java language,MySQL database technology,RFID technology and improved UDP protocol.The implementation overview of the front-end subsystem at the check-in site and the management subsystem at the center site are given.In this system,users are easy to operate and the user interface is friendly.Fifthly,the functions and performances of the system are tested.Specific software test methods,test cases and test results analysis are given.Finally,it shows that the system development meets the expected requirements.The system implemented in the study has been used in practical application.The development and implementation of this system can promote students to strengthen extracurricular physical exercise and promote the development of campus information and big data applications.
