Design of RFID Access Control System Based on Raspberry Pie

This paper focuses on the research background and status of the system design of RAFID access control based on raspberry pie, the construction of hardware circuits, the working principle of each module, the design of software programs and the process of physical debugging. The main reason for setting up the topic is to change the original human guard. Although the original human guard was flexible, but the irreversible personnel mobilization could not be quickly adjusted, resulting in management loopholes. The modern access control system not only reduces labor costs, but also makes flow management more standardized. In this paper, through the detection of face feature information and RFID card identification code, the data collected is transmitted to the raspberry pie through the trigger module (photo module and RFID module), and the raspberry dispatch database or photo library is compared and verified. If the match is successful, it will also be transferred to the computer to display the measured results, and then let the driver module operate to open the valve. This raspberry pie design raspberry pie as the core module, the function of RFID plus face recognition is the innovation of this access system, as long as one of the two recognition successes can open the door valve. This design, through the face recognition principle, RFID recognition principle, WiFi communication methods and other aspects of mastery and analysis, has planned and designed to complete the convergence between various modules, and finally completed the design, to achieve access control systems of two recognition modes.
