【摘要】 针对现有箱式变电站远程监控现场通信技术的不足,提出一种基于ZigBee技术的箱式变电站远程监控系统方案。系统共分为3层,底层为箱式变电站内部各监控子系统层,中间层为ZigBee网络与GPRS网络传播层,顶层为上位机监控系统层,可实时显示和反映箱式变电站的具体运行状况。详细阐述了方案中ZigBee网络各节点的硬件结构、与各监测对象的连接、供电选择等具体设计细节,以及基于软件环境VC6.0的监控软件。该方案具有低成本、高效率、拓展性强等特点,具有广阔的应用前景。更多还原

【Abstract】 Deficiencies of the existing box-type substation remote monitoring field communication technology,a remote monitoring system based on ZigBee technology for box-type substation was proposed,system was divided into three layers. The first layer were monitoring subsystems for supervision objects in box-type substation;the second layer was the ZigBee and GPRS communication network;the third layer was the central computer’s monitoring and controlling,reflecting real time operation condition of box-type substation. The application of ZigBee technology in monitoring system for box-type substation was mainly explained,such as hardware structure of ZigBee network node,connections with supervision objects and choice of power supply mode,monitoring software based on VC6.0 was developed. The system was suitable for the on-line monitoring of box-type substation with low operating expense,high efficiency and expandable,and it has a broad application prospect in the field of monitoring.更多还原
