摘要
介绍了一种基于智能电表的3层分布式无线居民用户自动抄表系统。系统第1层为RS-485通信网络,负责智能电表中的用电信息采集,系统第2层为ZigBee Pro无线传感器网络,负责用电信息及设置参数的路由,系统第3层为通用无线分组业务GPRS(General Packet Radio Service)通信网络,负责数据的远距离可靠传输。分析了设计中的关键问题,如无线通信方案设计、无线传感器网络参数配置、多对一路由、网络安全及GPRS可靠通信等。该系统具有可靠性高、可扩展性强、运行费用低等特点。
A three-layer wireless automatic meter reading system for resident power user based on smart electricity meter is presented on this paper.The first layer is RS-485 communication network,which is responsible for collecting the power quantity of smart electricity meter;the second layer is ZigBee Pro wireless sensor network,which is responsible for routing the power quantity of smart electricity meter and setting parameters;the third layer is GPRS communication network,which is responsible for a reliable long-distance data transmission.The key problems in design,for example,the design of communication,configuring the parameters of wireless sensor network,many-to-one routing,network security and GPRS reliable communication are analyzed.The system has many characteristics,such as high reliability,strong expansibility,low operating expense and so on.
