RF technology based electronic attendance system and method specially used for students

Abstract

The invention discloses an RF technology based electronic attendance system and method specially used for students, and belongs to the technical field for student attendance. The system comprise an RFcard identification module, a data acquisition module, a central control module, an attendance data processing module, a statistics module, a record checking module, a data storage module, a prompting module and a display module. The RF card identification module divides information in an RFID label of a campus card into three authority levels that password is not needed, password is needed for verification, and password as well as face / fingerprint is needed for verification, verification may not need password or need strengthened password in different occasions, and convenient and rapid useof the campus card is kept while the privacy and interests of a card owner are protected; the attendance data processing module does not cause system abnormity due to small size of a file, and normalsystem operation is ensured; and the query performance for the attendance data is improved.

Description

Technical field [0001] The invention belongs to the technical field of student attendance, and in particular relates to a student-specific electronic attendance system and method based on radio frequency technology. Background technique [0002] With the rapid development of modernization, with the rapid development of modern science and technology, and the in-depth development of the reform of the teaching system of colleges and universities, colleges and universities have gradually established the ability to choose courses, schedule courses, schedule exams, choose majors, and elective courses by themselves. An educational administration management system featuring courses, experiment appointments, score review, credit system, etc., is mainly used to manage the entire process of students from enrollment to graduation, including student status management, teaching plans, course start / scheduling, course selection, score management, and experiment management , Graduation design and...

AI Technical Summary

Problems solved by technology

[0006] (1) The identity authentication method of the campus card used by students for electronic attendance is relatively simple. No matter whether password authentication is required or not, the password must be entered, and the authentication information is not detailed enough, so many students let their classmates hold their own campus cards. Participate in tests or attendance for yourself; RFID systems often have collision problems within the system, causing the system to be unstable

[0007] (2) Existing attendance data tends to exceed the limits of the system, resulting in system abnormalities and poor query performance of attendance data. The security of the current attendance storage system is low, and it is easy to be invaded to change or delete, resulting in data loss and storage inaccurate information

[0008] (3) The central control module currently used needs to process multiple nodes, and the server has a large load intensity, which is cumbersome to implement resource scheduling tasks, which brings inconvenience to subsequent data analysis
