基于RC500的智能门禁控制系统研究

Research on intelligent entrance guard system based on RC500

介绍了基于RC500的智能门禁控制系统的设计与开发,门禁控制器主要由射频天线、读卡模块、单片机控制系统及RS485通信接口组成,由RS500接口与PC机组成通信网络系统,并给出了AT89C52与MF RC500的接口原理图,对读卡程序进行了说明,最后给出了主要程序设计的流程图。

This paper introduces the design and development of the intelligent entrance guard system based on RC500 circuit chip. Through RS485 interface and PC, constituting the communication network, the entrance guard controller consists of RF antenna, reader module, RS500 communication interface and MCU. Firstly this paper gives the interface principle diagram of AT89C52 and MF RC500, then the card-read program is illustrated, finally the main flow-chart is given.
