摘　　要：高压输电线路在线监测系统对保障输电线路的安全运行具有重要意义。根据高压输电线路的布局和监测参数的特点,设计并实现了一种层次型异构无线传感器网络。子网为Zigbee网络,负责图像和标量数据的采集;骨干网为基于IEEE 802.11的多跳自组织网络,负责数据的远距离可靠传输。设计了全参数高压输电线路监测系统,分析了设计和实现中的关键问题,如节点供电、传输距离、电磁兼容等。该系统具有可靠性高、可扩展性强、运行费用低等特点,尤其适合中国穿越偏远地区的高压输电线路的在线监测。In view of the great significance of the high-voltage transmission line on-line monitoring system to protecting the transmission line safe running,a hierarchical heterogeneous wireless sensor network is designed and implemented according to the layout of the high-voltage transmission lines and the characteristics of the parameters monitored.The network consists of a backbone network and a sub-network,the latter adopting Zigbee technology being responsible for collecting images and scalar data.The backbone network is based on IEEE 802.11 multi-hop ad hoc network that enables reliable long-distance transport.A high-voltage multi-parameter monitoring system is designed and implemented. Some key problems during implementation are discussed and an application case is presented. The system designed is especially suitable for high-voltage power line through remote districts for its high reliability, scalability and low cost.
