Abstract: In order to realize substation no-man control, this paper designed a kind of temperature real-time monitoring system based on ZigBee technology, selecting layer-divided topologic structure, and adding stronger isomeric structure nodes of data processing, storage and communication etc abilities in common nodes, so as to increase wireless transmission distance, to reduce cable laying. Combined with CAN and general packet radio service (GPRS) technology, the system realized temperature real-time monitoring and alarming functions, which effectively prevents power accidents from taking place due to equipment over temperature.
Key words: wireless sensor networks; temperature monitoring system; ZigBee technology; general packet radio service technology
