摘要
为实现架空输电线路的自动监测,优化设计了一种架空输电线路无线监测系统。该系统可实时监测架空输电线路中的温度、湿度、风速、拉力等参数,并通过多跳的方式将数据传输到监控中心和云服务器。基于Zigbee技术,组建了链式无线传感器网络;基于CC2530芯片,设计了无线传感器节点;使用放大电路,将最大监测风速降至40 m/s,提高了测量精度;利用仪表放大器,设计了拉力传感器信号调理电路,并采用太阳能电池板供电。测试结果表明,该系统能够实现架空输电线路参数的监测,也可应用于其他类似场合的环境监测。
In order to implement the automatic monitoring of overhead transmission lines, the wireless monitoring system is optimized and designed. 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.
