The Design of a Campus Access Control System Based on ARM

Abstract

Nowadays, with the in-depth development of networking, informatization and integration the access control system has become more and more popular and important in campus. Most access control systems were developed based on MCU with the characteristics of fixed functions and hardly to extend. A kind of campus intelligent access control system based on ARM is introduced in this paper. The overall structure of the system is as follow: the communication way between host computer and the access controller is TCP/IP protocol; using CAN-BUS for communication between access controller and RFID reader. In the design process, top-down design ideas has been adopted. From the overall structure to the local design, from the host computer to access controller and RFID reader, by means of functional analysis, process planning, hardware design and software programming, finally developed a campus intelligent access control system with excellent exhibitions on powerful, stability and scalability.
