An Icing On-Line Monitoring System of Transmission Lines Based on WSN

According to the erecting features of transmission lines and the monitoring data type, an icing on-line monitoring system of transmission lines based on WSNs is designed. This paper presents a hierarchical wireless sensor network based on Zigbee technology, after analyzing the limitations of communication methods used by existing monitoring system. The bottom basic layer of the network is responsible for collecting the monitoring data, while the function of the top backbone layer is to relay data. By this way, the coverage of the network can be improved. In this paper, the hardware and software of the nodes are designed, several key problems are discussed at the same time, such as the networking process and node´s power supply.
