智能防雷监控系统

Intelligent Lightning Protection System

介绍了防雷监控管理系统,采用的ABB双向主动访问总线是由工业总线改进的,解决了RS-485总线系统在终端出现问题等待上级管理站查询发现的被动、查询速度慢的问题。终端装置一方面被动接收上位机查询,另一方面主动上报问题,具有通信速度快、抗干扰能力强特点。在双向访问总线技术支持下,防雷监控系统实现了SPD劣化(剩余电流)检测、后备保护器自动或手动远程控制分/合闸。

This paper introduces the lightning detecting and controlling system, which adopts ABB bi-directional aetively visiting the industrial bus technology. It solves the problem that when there are problems occurred in the terminal of RS-485 bus system, the terminal has to wait passively for the query of superior management station and it is not allowed to visit the station actively, which makes the query low speed. The new terminal device, waits passively for the query of superior management station and reports the problems actively. It has the charaeteristics of high speed communication and strong anti-interference capability. Supported by bi-directional visiting bus technology, the lightning detecting and controlling management system can detect SPD degradation （leakage current）, reclose SPD external disconnector in among manual ,automatic or remote control status.
