Research On Campus Attendance System Based On Wireless Transmission Technology

The country vigorously cultivates outstanding university students,and implement the strategy of rejuvenating the country through science and education,In order to reduce college student absence rates,and improve the level of university intelligence.In order to solve the problems of large workload,low efficiency,waste of manpower,and false information in the traditional attendance system,this paper proposes a fingerprint attendance system based on wireless transmission technology.In this paper,we mainly study the fingerprint identification system,and analyzed the fingerprint recognition system category and fingerprint characteristics,and selected the appropriate fingerprint collection technology.We use grayscale normalization and equalization,image segmentation and enhancement methods to improve fingerprint image quality.We also studied the three quality scores of fingerprint images to discuss the quality assessment methods of fingerprint images.Based on the 80C51 microcontroller,we use FPM101635 sensors and other devices to design the software and hardware system for fingerprint identification;complete the circuit design of fingerprint storage,wireless transmission,signal reception and power circuit modules,and build a fingerprint attendance system based on wireless transmission technology.We analyze attendance system operation logic,write matching program,and design attendance system software.The campus management system designed in this paper implements functions such as user management,personnel information management,fingerprint registration and login,and attendance query summary.It's also based on the evaluation indicators of the campus attendance system,fingerprint image and system performance tests were performed.Experimental results shows that the fingerprint image quality was highly accurate and the system performance meets campus attendance system usage requirements.
