Development of wireless monitoring system for power high voltage contacts' temperature

According to requirements of measuring high voltage contacts' temperature in power system,a set of high voltage contacts' temperature wireless monitoring system is developed.The system consists of wireless temperature sensor nodes network,wireless telemetering network,and monitoring host computer.The wireless temperature sensor nodes are measured by DS18B20.CC2430 single-chip reads temperature data and the flexible network is realized by ZigBee wireless communication technology.Wireless telemetering network is interconnected by wireless temperature monitor through CAN bus.And the wireless temperature monitor,as the main node of ZigBee subnet,is responsible for receiving nodes' temperature data and transferring data to host monitor computer.Host monitor computer completes the display,estimation,and store of all nodes' temperature.The system is put into operation on site.The performance of the system is good and provides a strong support for the safe operation of the power system.
