Design And Implementation Of Intelligent Mobile Classroom Attendance System Based On Multi-modal Mutual Certification Mechanism

With the increase in the number of students enrolled in colleges and universities,the classroom attendance of students has become the focus of the school.At present,many colleges and universities mainly adopt classroom attendance methods such as verbal naming,paper check-in,time card attendance,fingerprint recognition attendance,and face recognition attendance.These attendance methods all have certain shortcomings and deficiencies.To make up for these shortcomings,some advanced attendance technologies are combined for identity recognition,which has the advantages of high recognition rate and strong adaptability,and it has become the direction of intelligent attendance system.This paper mainly proposes a mobile intelligent attendance system,which is based on embedded technology,biometrics technology,computer technology,network communication technology,information processing technology and other technologies.The attendance system uses the STM32F4 development board to combine RFID technology,fingerprint identification technology and face recognition technology.And it has the advantages of high efficiency,accuracy,real time,flexibility,and strong mobility.The attendance system uses.STM32F407ZGT6 as the main control chip.I have completed the construction of all hardware devices,including the data collection and transmission of RFID module,fingerprint identification module and face recognition module,the LCD module display of personal information,photos and other system status information,and the data transmission of the network transmission module.According to the functional requirements of the system,the software part is designed,focusing on the specific design and implementation of the main program,RFID module,fingerprint recognition module and face recognition module function program,and completed the design of the human-computer interaction interface and database.Finally,the test of the attendance system are carried out,and the results show that the single module function and the overall function of the system can meet the system requirements and achieve the expected attendance objectives.The application of attendance data also has a strong practical significance for future teaching.
