The parameters of overhead transmission lines,such as temperature,humidity,wind speed and tension can be monitored in real time,and then transferred to the monitoring center and cloud server via multi-hop mode. Based on Zigbee technology,a chained wireless sensor network is constructed. Based on the CC2530 chip,the wireless sensor nodes are designed to enhance the measurement accuracy,the amplification circuit is used to reduce the maximum monitoring wind speed to 40 m/s;the tension sensor signal conditioning circuit is designed by adopting instrument amplifier;the nodes are powered by solar panels. The results of experimental tests show that the monitoring of the parameters of overhead transmission lines can be achieved by this system. It can be used for environmental monitoring in other similar fields.
