摘要
针对高压输电线路的分散性大,所处地理环境、气候条件复杂的现状,以实际项目开发为背景,设计了一套以GPRS和ZigBee无线传感器网络技术为基础的输电线路综合监测系统。该系统中由传感器节点采集导线拉力、倾角和气象等信息,由ZigBee无线传感器网络传输到监测子站系统进行数据融合处理,并通过GPRS公网把数据传回主站监测系统。文中详细阐述监测子站和无线传感器节点模块的硬件结构,以及导线弧垂在线监测装置的工作原理,给出主站系统、子站系统的软件工作流程。该系统经实际运行测试,结果表明:基于ZigBee技术的输电线路综合监测系统具有良好的可扩展性、可靠性,功耗较低,维护方便,是目前行之有效的方法,完全可以满足输电系统在线监测的需要。
Aimed at addressing the larger dispersion of the high-voltage transmission lines and more complicated geographical environment and climatic conditions to which these lines are exposed,this paper designs a set of on-line comprehensive monitoring system for power transmission line based on GPRS and ZigBee technology.The system works by enabling sensor nodes to obtain the information associated with wire tension,dip Angle and weather,which are transferred to sub-station monitoring system by wireless sensor networks for data fusion process before the substation system transfers these fused data to mainstation system by GPRS wireless public network.The paper details the hardware structure and software process of main station system,sub-station system and sensor nodes.The power transmission line monitoring system based on ZigBee technology boasts such advantages as a greater scalability,more reliable performance,lower power consumption,and easier maintenance and thus works as an effective method quite up to the needs of power transmission system for on-line monitoring.
