High-voltage power line stressing and cracking monitoring system based on wireless sensor network

The invention provides a high-voltage power line stressing and cracking monitoring system based on a wireless sensor network, comprising a wireless sensor node network and a background monitoring center, wherein the wireless sensor network comprises a sensor node for collecting power line stress data and environment data, and a Sink node for transmitting the data; the sensor node is connected with the Sink node; the Sink node is connected with the background monitoring center; one sensor node is placed on each electric pole and comprises a temperature and humidity sensor and tension sensors which are connected with the electric poles and arranged at the high part of a power line; the tension sensors are connected with a wireless sensor node through a shielding line; and the background monitoring center comprises an abnormal monitoring module which is used for comparing collection tension force with pre-set maximum snapping force, and sending out an alarming signal when the tension force is more than the maximum snapping force. According to the high-voltage power line stressing and cracking monitoring system, the power consumption is low and the accuracy and the instantaneity of monitoring are improved.
