Monitoring device and monitoring method of lightning arrester

Abstract

The embodiment of the invention provides a monitoring device and monitoring method of a lightning arrester. The method comprises the following steps that: a synchronizing clock starts timing and whether preset synchronization time is reached is determined; if so, the synchronizing clock controls a physical switch driver to connect a physical automatic switch and controls a signal collector synchronously to collect a lightning arrester signal; the signal collector collects lightning arrester signals N times under control of the synchronizing clock, wherein the N is an odd number not less than 3; and a transmission unit transmits the lightning arrester signals collected by the signal collector N times to a monitoring unit, so that the monitoring unit determines whether the lightning arresterworks normally based on the N-times lightning arrester signals. Therefore, the lightning arrester and the signal collector can be isolated effectively and the lightning stroke risk of wired or wireless connection of the signal collector is avoided to the greatest extent, thereby guaranteeing the normal operation of collection.

Description

technical field [0001] The invention relates to the technical field of information communication network management, in particular to a monitoring device and a monitoring method for a lightning protector. Background technique [0002] At present, all communication power surge protectors are not remotely monitored, requiring professionals to go to the station to check one by one, so that some damaged lightning protectors cannot be replaced in time, leading to major failures, resulting in a large loss of manpower and material resources. figure 1 Shows the current position of the SPD on the communication network. Such as figure 1 As shown, at present, the lightning protection of communication equipment is mainly divided into two levels, namely A-level lightning protection and B-level lightning protection. These two lightning protection devices can only be found by on-site inspections at present. [0003] The function of the lightning arrester is to cut the amplitude of the in...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the existing technology mainly requires professionals to carry out regular inspections on the station, which will consume a lot of manpower and material resources, and the failures that occur during the inspection interval cannot be avoided, so there are hidden dangers of major failures

At the same time, because the dynamic environment monitoring in the communication field all adopts wired monitoring, because the instantaneous current of lightning is very large, all equipment connected to the line may be damaged by lightning, so if the lightning protection device is connected to wired or wireless monitoring, there will be a large security risks
