RFID portable class attendance check system and method based on campus one-card-pass

Abstract

The invention relates to an RFID portable class attendance check system and method based on campus one-card-pass. The system comprises a power module, an input module, a central processing unit, a display module, an indication module, a storage module, an RFID read-write module and a low voltage detection module, wherein the central processing unit, the display module, the indication module, the storage module, the RFID read-write module and the low voltage detection module are connected with the power module. Campus IC cards are combined with the radio frequency identification (RFID) technology, campus card resources are fully used, attendance burdens of teachers are reduced, and the system is small in size and convenient to use. The average achievement of every student can be automatically counted according to the attendance condition of the student in the end of term, manual calculation of teachers is omitted, attendance check and achievement counting integration is achieved, and the system is responsible for attention check work in the whole process.

Description

technical field [0001] The invention relates to an attendance system, in particular to a campus one-card RFID portable classroom attendance system and method. technical background [0002] It is not uncommon for college students to skip classes now. In order to control the class attendance rate of students, teachers in colleges and universities currently mainly use manual roll call and self-sign-in methods to check students' attendance in class, but there are the following disadvantages: [0003] 1) Each roll call takes a certain amount of time and takes up classroom teaching time, and reducing the roll call will cause students to be lucky and absent from class; 2) Some students take advantage of others to answer "yes"; 3) Some students replace others to "sign" The phenomenon. 4. To prevent this kind of phenomenon from happening, teachers usually ask the students who are called to raise their hands to remember the students who answered "yes" during the roll call process, wh...

AI Technical Summary

Problems solved by technology

[0003] 1) Each roll call takes a certain amount of time and takes up classroom teaching time, and reducing the roll call will cause students to be lucky and absent from class; 2) Some students take advantage of others to answer "yes"; 3) Some students replace others to "sign" The phenomenon

4. To prevent this kind of phenomenon from happening, teachers usually ask the students to raise their hands to remember the students who answered "yes" during the roll call process, which brings additional burden to the teachers

Patent 02159516X (multifunctional offline fingerprint time attendance machine) and 201010180107 (time attendance machine) use fingerprint time attendance, and the recognition rate of fingerprint time attendance is low. When using it, you need to wash and dry your hands, otherwise it is easy to be unrecognizable or even recognized as someone else's fingerprint, etc. In addition, if the palm is injured, the change of the palm print cannot be recognized, and the recognition rate of the card swiping module has reached 100%. In addition, the life of the fingerprint recognition module is much shorter than that of the card swiping module, and the comprehensive use cost is relatively high; patent 03100055X (paper card attendance machine card number Identification method) need to use a separate attendance card, the cost is high and the user is inconvenient to carry; the patent 200510029805X (voiceprint time attendance machine) uses voice attendance, and the recognition rate is low, especially when the user's throat is sick, the voice will have a certain The change of the system leads to unrecognizable situations; the patent 2004100745025 (Student Electronic Attendance and Real-time SMS Sending System) has complex devices, numerous communication cables, high cost and failure rate, and once a failure occurs, it will directly affect the attendance work; the patent 2013103052304 (iris attendance machine): need to enter the attendance information before use, which is not practical in classroom attendance; patent 2015109620165 (a face recognition method and attendance system based on deep convolutional neural network) adopts the face recognition attendance method, It is easy to be deceived by using the photos of attendance attendants to achieve falsification of attendance
