摘　　要：为了提高输电线路的监控管理水平,开发了一种输电线路状态远程监测系统.本系统可以对输电线上的温度和电流实时监测,能够对输电线路故障进行定位和预警.本系统使用GPRS无线公网、光纤专网和230MHz无线专网等多种远程通信方式,使监控站点与控制中心的通信更加灵活.监控站点内使用ZigBee和WiFi无线通信技术完成数据采集与交换,在保证可靠通信的前提下,降低了系统成本.实测表明,该系统运行稳定可靠,并且具备成本低、功耗低等优点.In order to enhance the monitoring and management level of the transmission lines, a remote monitoring system for transmission line status is developed. This system monitors the temperature and current of the transmission line real time and offers forewarning and fault location of the transmission line failure. The system uses multiple telecommunication modes, including GPRS wireless public network,optical private network and 230MHz wireless private network. It makes the communication between the monitor site and the control center more flexible. It uses ZigBee and WiFi technology to collect and exchange data which ensure reliable communication and reduce the cost. Practical test indicates that the system is running stable and reliable and has the advantages of low cost and low power consumption.
