一种基于ZigBee的无线抄表系统研究与设计

摘要

A three-layer wireless meter-reading system based on the short-range wireless communications technology ZigBee is proposed. The system consists of the collector, the router and concentrator based on low power system-on-chip CC2530, and combines ZigBee wireless sensor network for data communication with long-range wireless network GPRS. The system has the features of distribution and centralization, and can realize that each data acquisition modules collect periodically the data of electricity meter in active mode, even that a variety of meter-reading ways such as unicast, multicast and broadcast in passive mode. Besides, it has low power, low cost and high reliability of data transmission%提出了一种基于短距离无线通信技术ZigBee的三层分布式无线抄表系统,系统由低功耗片上系统CC2530构成采集器、路由器、集中器,采用ZigBee传感器网络进行数据通信,与远距离无线网络GPRS相结合,系统兼具分布式与集中式的特征,可实现在主动抄表方式下各数据采集单元的定时采集,以及被动抄表方式下单播、组播和广播等多种集抄方式,且具有低功耗、低成本、高可靠性数据传输的特点.
