摘要
为了实现对架空输电线路覆冰情况的实时监测,根据输电线路架设特点及监测数据类型,设计了一种基于WSN(无线传感器网络)的输电线路覆冰在线监测系统。在分析现有覆冰监测系统通信方式的局限性的基础上,监测系统通讯采用基于Zigbee协议的层次型无线传感器网络,从而提高了网络覆盖范围。文中主要对传感器节点的硬件和软件进行设计,同时分析了网络组网、传感器节点供电等关键问题。在实验室环境下,针对所设计的层次型无线传感器网络中各传感器节点之间数据传输性能进行测试。测试结果表明:各节点硬件软件运行正常,组网和数据传输性能良好,能满足该监测系统要求。
In order to monitor transmission lines icing state in real time, an on-line monitoring system based on WSN was de- signed according to the erecting features of transmission lines and the monitoring data type. A hierarchical wireless sensor network based on Zigbee technology was adopted in this system, after analyzing the limitations of communication methods used by existing monitoring system. By this way can improve the coverage of the network. The sensor nodes applied to wireless networks were de- signed in hardware and software. Meanwhile, several key problems were discussed, such as the networking process and node＇ s pow- er supply. In laboratory environment, the testing for data transmission performance between each node in this hierarchical wireless sensor network was operated. The result shows that the nodes operate properly in both software and hardware with better networking and transmission performance, which can satisfy the requirement of the monitoring device.
