To measure and control thermal defects of power station, continuous power is provided to the ZigBee wireless temperature sensors by using monocrystalline silicon solar cells and thermoelectric generation modules, which can collect and process the real-time temperatures of high voltage equipments in the station. Simultaneity, the system can solve the problem that overheat faults can not alarm timely when efficiency of solar cell decreases during the continuous rainy days. The remote real-time controlling is realized by using client and server programs of VC + +.NET. The lossless compression and real-time image transmission are implemented through employing the screen grid-division method and the Huffman compression algorithm. All of these provide a technical assurance to the remote controlling of heat vice of high-voltage equipments in multi-stations.
