针对传统门禁系统功能单一、效率低下、布线复杂等问题,提出了基于ARM的无线门禁控制系统.选择高性能的32位ARM器件LM3S6918作为门禁系统的主控制器,采用非接触式IC智能射频卡Mifare实现用户身份认证,选用GPRS模块MD600A DTU实现门禁控制器与上位机之间的无线通信.通过实验证明,系统具有功能多样化、处理效率高、布线简单的优点,可以满足现代化门禁系统的监控要求.%As traditional access control systems have shortcomings such as single function, inefficient, wiring complexity and so on, this paper proposes a wireless access control system based on ARM In this system, the communication between the host computer and access controller is by wireless, instead of the wired to avoid s series of problems caused by wiring The key control chip of the Access controller is ARM, instead of traditional single-chiprnmicrocomputer, which does not only increase processing speed and storage capacity, but also increases hardware resources It can support more peripheral circuit and realize more function, so it can better meet the needs
