中文摘要：

由于电力线在严重覆冰的情况下常常导致断线、倒塔等事故,而电力公司却不能预测电力线何时将要断裂,且事发后不能快速确定具体位置,以致无法及时抢修。为解决这些问题,设计了一种基于无线传感器网络（WSN）的电力线受力监测系统,通过部署在电力线上的传感器节点来实时采集电力线的受力参数,并将状态数据传输至汇聚节点,由汇聚节点通过GPRS网络传送至监控终端,监控终端对可能出现的电力线断裂情况进行预警。研究结果表明,该系统可以减少传统人工监测的高额成本,并提高监测的可靠性。

英文摘要：

When a power line was covering by too much ice,it would always cause accidents of fracture and collapse.But power companies didn＇t know when the line would fracture and didn＇t know the accurate location after it fractured.So the lines cannot be repaired timely.In order to solve these problems,the electric line monitoring system based on wireless sensor network（WSN） was designed,which can collect real-time mechanical parameters of the line by sensor nodes on it,and then sensor nodes transmit state data to sink node.Through the Internet by sink node the state data can be transmitted to monitor terminal,and it can have advance warnings when the line will fracture.The system can reduce the high cost of traditional manual monitoring,and improve the automation and reliability of monitoring.
