基于RC500的IC卡实验室门禁管理系统的实现

Access Control Management System of Open Laboratory Based on RC500 IC Card

介绍了基于RC500的实验室门禁管理系统的设计与实现,并给出了部分接口原理图和主程序设计的流程图.系统采用分布式集中控制方案,利用RS485总线,提高了系统的实时性和稳定性.系统软件程序采用C语言编写,大大提高了系统开发调试的工作效率,且具有很好的移植性.

The paper introduces the access control system which takes an important role in the open laboratory system. It is composed of radio frequency antenna, reader module, clock modules, electric lock control module, and a single-chip microcomputer control system with double RS485 communication interfaces. The reader module is based on Philips RC500. Partial schematics interface and the main program flow chart are presented.
