论文基于Zigbee和GPRS设计了无线自动抄表系统。本地无线信道由Zigbee组成的多层树状网络构成,Zigbee网络节点运用载波侦听多点接入/避免冲撞(CSMA-CA)算法判断信道使用状态,远程信道由GPRS构成,系统考虑了安全性并提出了解决方法。系统具有较强的抗干扰能力,通信稳定可靠,适合在中国电力系统中大量推广。A wireless automatic meter reading system is designed based on the Zigbee and GPRS in the paper. The local radio channel is formed by the multi-layer tree Zigbee network, Zigbee network nodes use carrier sense multiple ac-cess/collision avoidance (CSMA-CA) algorithm to determine channel usage state. The remote channel is constituted by the GPRS system with security. The wireless automatic meter reading system presented in this paper has strong anti- interference ability, stable and reliable communications for a large number of power systems.
