摘　　要：针对现有电梯监控系统布线繁琐,容易出故障的现象,提出使用无线通信的方式传输电梯监控数据。以德国奔克bp304控制系统为平台,采用NRF905射频芯片为无线收发器,M051单片机为主控芯片设计的无线收发模块,并通过功率放大器增加无线通信距离。经过实际测试,通信有效距离达到了1 km,无线通信不仅有效地解决了布线问题,而且节约了整个监控系统的成本。Because of complicated wire arrangement with high cost and less safety in elevator monitor system, wireless communication was adopted to transfer elevator data. Based on bp304 elevator control system, a wireless module was designed by using M051 as controller, NRF905 as wireless transceiver, and a power amplifier used to extend the distance of communication. The practical experiment proved that effective wireless communication distance is 1 kin. The wireless communication not only solves the problem of wire arrangement but also save the cost of the monitor-control system. [ Ch,7 fig. 10 ref. ]
