Design Of Intelligent Access Control System Based On STM32

With the continuous improvement of science and technology,and the people’s living standard,intelligent building will play an important role In the future of urban construction.Door-control system is a essential key component of the field of intelligent building.It can not only control the access authority of personnel,but also monitor and record the access of these personnel in real time,which is an indispensable security and prevention facility of intelligent building.The identification medium of Radio frequency identification access control system is easily lost and damaged,and the fingerprint identification access control system is easily affected by the environment.This design makes a brief analysis of the current research status and development of the access control system and proposes a design scheme of intelligent access control system based on STM32 by combining with the RFID technology and fingerprint identification technology research.This design scheme adopts fingerprint identification technology and radio frequency identification technology to verify the identity,and completes the multiple verification of the access control system,which can avoid the hidden danger of single access control system and improve the stability and security of the system.The specific design scheme is as follows:In terms of hardware,it adopts STM32 as the controller to build the overall hardware architecture of access control system terminal by combining power supply,radio frequency identification,fingerprint identification,relay and other modules.In terms of software,it adopts modular design ideas to design and develop the main program design module,fingerprint identification access control module and RFID access control module.The upper computer adopts C# language to realize the design of access control management system.In the face of the challenge of ‘Internet plus’,internet of things and mobile intelligence,the continuous innovation of access control technology makes access control system enter an unprecedented transition period.The single verification method of access control system is gradually be replaced,and intelligent access control system will become the future development trend of the access control industry.Figure 44;Table 13;Reference 41...
