Study on Remote Monitoring System for Vibration State of Transmission Tower

根据输电铁塔振动监测的实际要求与特点,设计了输电塔振动状态远程监测系统。该系统可以自动采集输电塔的振动状态参数和当地气象数据,并通过无线网络在远端监控中心的主计算机系统上显示、处理测量结果,实现了振动信号的网络化实时采集和传输。现场应用情况表明,系统具有实时性强、可靠性和准确性高、可移植性好等特点。该系统对于特高压1 000 kV线路以及过江、过峡谷、台风和裹冰多发地区输电塔的远程健康状态监测有一定的参考价值。

A remote monitoring system for vibration state of transmission tower was developed according to the requirement and the characteristics of transmission tower vibration monitoring. This system includes three key functions, including automatic collection of vibration state parameters and local weather data, the displaying and treatment of measure results on main computer system of remote monitoring center through wireless network, real-time collection and transmission of vibration signals. Being installed in the transmission tower for nearly three month, the system has run well and fulfilled the expectant goals very well. The results show that the system is excellent in the many aspects, such as real-time performance, reliability, accuracy, transplantation and so on. The design of the whole system, the performance of both software and hardware and the functions of the system are described in detail in this paper.
