摘要
输电线路在线监测系统对保障输电线路的安全运行具有重要意义。根据高压输电线路的布局和监测参数的特点,设计并实现了一种层次型无线传感器网络。子网为ZigBee网络,负责传感器数据的采集;骨干网为基于IEEE 802.11的多跳自组织网络,负责数据的远距离可靠传输。设计了输电线路在线监测系统的无线传感器节点和监测子站,介绍了其软件和硬件结构。进行了无线链接质量测试,得出常对数距离衰减模型与实测数据相符,可以通过接收信号强度指示(RSSI)值判断无线通信质量。
An on-line monitoring system is of great importance to ensure the safety operation of power transmission lines. A layered wireless sensor network （WSN） is designed based on arrangement and monitoring parameters of transmission line. ZigBee based sub-network aims to collect data from sensors and IEEE 802.11 based backbone network is designed for transmitting data with a long distance reliably. Wireless sensor nodes and monitoring substation of on-line monitoring system are designed, and corresponding hardware and hardware of them are introduced. A wireless link quality experiment is implemented, which shows that constant logarithmic distance decay model is highly consisted with the measured data, and RSSI could be taken as an indicator of the radio link quality.
