摘　　要：为实时监测输电导线的舞动状态,在ZigBee Pro Feature set(ZigBee PRO)无线通信技术的基础上提出了导线舞动多点监测系统的设计思想。分析了ZigBee PRO技术在导线舞动监测应用中所需要解决的关键问题,该系统采用分布式测量系统构架,对系统中用于构建无线网络的协调器节点和用于监测舞动的传感器子节点在硬件和软件方面进行了分析与设计,利用三轴加速度传感器实现了对导线舞动轨迹的多点同步监测,为导线张力变化的计算打下了基础。在实验室环境下,针对加速度数据采集精度和通信质量等方面进行了实验,实验结果表明,设计开发的系统软硬件运行正常,组网和传输性能良好,能够满足实时导线舞动监测应用的基本要求。In order to monitor the transmission line galloping state in real-time, a multi-point monitoring system for conductor galloping based on the principle and protocol of ZigBee Pro Feature set （in brief ZigBee PRO） is devel- oped. Meanwhile, key problems of ZigBee PRO technology which is applied in monitoring tran.smission line gallo- ping are analyzed. Moreover, the distributed measuring system structure is applied in the system, and the coordina- tor node and sensor node which are applied to wireless networks are analyzed and designed in hardware and soft- ware. Then, three axis acceleration sensors are designed to realize multi-point synchronous monitoring, which lays foundations for wire tension calculation. In laboratory environment, experiments of data acquisition and communica- tion quality are operated in a wireless acquisition system. The results show that the developed system operates prop- erly with better performance in networking and transmission. And the multi-points monitoring system for conductor galloping can satisfy the requirements of real-time monitoring the transmission line galloping.
