Abstract: 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.
