In view of the great significance of the high-voltage transmission line on-line momtorlng system to protectlng 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,sealability and low cost.
