摘要
针对传统机械式门禁系统的开启能力差、不易于集中管理的缺陷以及基于CAN总线的智能门禁布线复杂、安装难的缺点,提出一种基于Zigbee的智能门禁系统设计方案。该系统由分布式电子锁、主控制器和上位机组成,以MSP430为控制核心,采用基于NRF905的Zigbee模块进行通信,实现了分布式电子锁的数据采集以及开关状态的控制。该系统可以应用于变电站的机柜门禁系统,具有响应时间快、低功耗、可靠性高的优点。
Against the traditional mechanical entrance guard system anti-open is poor,not easy to centrally manage and the intelligent entrance guard based on CAN bus complex wiring,difficult to install,the design scheme of an intelligent entrance guard based on Zigbee is proposed.The system consists of the distributed electronic lock,main controller and upper units to control core MSP430.Based NRF905 using the Zigbee communication module,a distributed data acquisition and electronic lock control switch state.With the advantages of fast response time,low power consumption and high reliability,the system can be applied to substation cabinet entrance guard system.
