摘要
阐述了一种智能门禁系统的硬件设计,该系统采用射频IC卡技术,以AT89C52为核心研制门禁控制器,门控部分向上通过RS485-RS232转换器连接到管理中心计算机,上位机通过网络可对各个住户的门进行监控和管理.该系统已在北京市某小区投入使用,实践证明系统设计合理,运行稳定可靠.
A hardware design of intelligent access control system is introduced in this paper. The intelligent access controller is developed by the technology of radio frequency IC card and micro-controller AT89C52. The controllers connect to the computer of center, and the computer monitors the doors of every tenement. The system has run in a uptown in Beijing. The operation results show that the design of the system is reasonable and stable.
