应用ZigBee技术的变电站周界安全监控系统

摘要

For the problems existing in anti-theft systems for unmanned substation, such as difficult wiring and heavy maintenance, a safety monitoring system for unmanned substation based on laser, ZigBee and GPRS technology is introduced. The system consists of laser fence anti-theft subsystem and supervisory control subsystem. The former uses laser to real-time acquisition of alarming information and send it to the supervisory control subsystem via ZigBee wireless sensor network quickly. The later subsystem receives the alarming signal and displays on the server, and meanwhile, the system sends message to operator on duty via GSM network. Wireless data transmission as well as centralized computer monitoring and management is realized in the system. The system is applicable for the similar field.%针对目前无人值守变电站有线防盗系统、布线困难、维护工作量大的不足,应用激光技术、ZigBee无线技术及GPRS技术设计了变电站周界安全监控系统.系统由激光围栏防盗子系统和数据中心监控子系统组成.激光围栏监控子系统采用激光作为传输媒介实时采集报警信息并通过ZigBee无线网络进行有效、快速传输；数据中心监控子系统接收报警信息并在服务器上显示,同时通过GSM网络给值班人员发消息告警.该系统实现了报警信息的远程无线传输和计算机集中监控、管理的功能,可广泛应用于其他类似的场所.
