Design And Implementation Of RFID-based Examination System For Chinese Academy Of Customs Administration

With the rapid development of education informatization,more and more intelligent devices,wireless sensing devices will appear on campus,they use information and intelligent means to improve the efficiency and effect of teaching,office and management,which is the primary work of the current universities.The in-depth development of the Internet promotes the continuous maturity of Internet of things technology.RFID technology is one of the important technologies of Internet of things.It can quickly identify objects and read data,with advantages of not easy to be forged,strong anti-interference ability,etc.At present,it is the most widely used in the field of automatic identification and the most mature technology,which is widely used in various scenarios of personnel identification.In this paper,based on the requirements for the construction of the examination information application of the customs college,combined with the advantages of RFID technology,the RFID-based examination system of the Chinese academy of customs administration was designed and developed to collect the real-time identification characteristic data of all the RFID tags in the range of radio frequency signals of students.In this way,it realizes the integrated management of making out questions,forming papers,taking exams,judging papers and checking scores.On the premise of ensuring safety,reliability and performance,it effectively alleviates the problems existing in the current examination work of the college,such as tedious examination work,high operation and maintenance cost and high operation and maintenance pressure.The main work of this paper is summarized in the following three aspects:Firstly,starting from the application research of campus informatization at home and abroad,it analyzes the problems existing in the examination work of Chinese Academy of Customs Administration in this paper,including difficulty in forming papers,identical test papers,leakage of examination questions,great difficulty in management,high operation and maintenance cost,etc.,It further analyzes based on these problems and obtains the functional requirements,system use case analysis and system performance requirements of the examination system construction of Customs College.Secondly,according to the requirements of the examination system of Chinese Academy of Customs Administration,the system application architecture design,technical architecture design and data architecture design are carried out.Based on these above,it designs five core modules of system construction,which are respectively examinational affair management,examination management,student management,score inquiry and examination situation analysis,applies RFID identification technology to manage student test identification,combines with recursive algorithm to complete the design of forming papers,analyze the influencing factors of test questions,as well as explore the automatic question extraction algorithm,and completes the extraction of question bank by means of circular call design in this paper.Finally,the realization and verification of the system are carried out based on the overall design and detailed design of the system.Each module of the system is developed and implemented by using B/S system architecture of J2 EE standard,the software and hardware communication of RFID identification is completed,the availability of the algorithm of forming papers is verified,and the rationalization of test papers as well as automatic question selection is realized.Thus,the purpose of the research is achieved,and the practical application value of research results comes into being.
