基于ZigBee技术的电力设备远程监控系统

A Remote Monitoring System for Electric Power Equipment Based on ZigBee Technology

为了提高电力设备状态监控的可靠性和便捷性,针对传统的有线网络采集布线复杂和成本高的缺点,设计了一种基于ZigBee无线网络的电力设备远程监控系统。利用TI公司片上系统CC2530芯片作为ZigBee网络的路由器,通过RS485-RS232协议转换器将电表数据读入ZigBee网络,再利用片上系统CC2538芯片作为ZigBee网络的协调器,接收底层模块的数据并将数据上传至上位机以实现数据监控。采用了一种协调器单次问询,从设备周期性回复的通信方式,并在协调器中实现了数据存储、问询判断、掉线重发等功能以使整个系统协同,高效的工作。

To improve the reliability and convenience of electric power equipment state monitoring, this paper designs a remote electric power equipment monitoring system based on ZigBee wireless network, against the shortcomings of complex collection and wiring as well as high cost of traditional wired networks. Having TI＇s SoC CC2530 as ZigBee router, electric meter data is read into ZigBee network through RS485-RS232 protocol converter. Then, SoC CC2538 is used as ZigBee network＇ s coordinator to receive data from the underlying module and upload it to the upper computer for data monitoring. This paper adopts a special communication mode which makes the coordinator ask one time and the routers will repeat periodically. Furthermore, the coordinator can perform such functions as data storage, enquiry judgment and retransmission in case of lost connection to enable the whole system to work in a collaborated highly efficient way.
