A portable remote monitoring system for temperature monitoring of live equipment in substations

Abstract

The invention discloses a portable remote monitoring system for monitoring the temperature of live equipment in a substation, which belongs to the electric power industry and includes: a video acquisition module, a control and data analysis module, a transmission module, a mobile phone APP and a cloud server; a control and data analysis module, It is used to set the automatic inspection plan of the video acquisition module through parameter setting, according to the corresponding relationship between the infrared thermal imaging image and the temperature value, analyze the infrared thermal imaging image collected by the video acquisition module to collect the infrared thermal imaging image of the equipment in the charged area, find the overheated equipment, lock and let the video acquisition module Shorten the distance with the overheating equipment, save the specific information and records of the overheating equipment, analyze and record the status of the video acquisition module itself at all times; display it on the mobile phone APP, and store it on the cloud server. It is convenient for management personnel to conduct on-site inspections through the mobile phone APP, and can understand the status of operating equipment in the live area of ​​the substation anytime, anywhere. Once there is an overheating fault or sudden fire point, it will be immediately known and dealt with in time to avoid greater economic losses.

Description

technical field [0001] The invention relates to the electric power industry, in particular to a portable remote monitoring system for temperature monitoring of electrified equipment in substations. Background technique [0002] Existing substation live area temperature monitoring systems generally have the following deficiencies: the existing technology is not intelligent enough, managers can only subjectively analyze and judge the operating temperature of substation live area equipment through a specific screen, and the monitoring system cannot make independent judgments Whether the equipment is overheated, which equipment is overheated, where is the specific space, and what is the reason for the overheating, which makes the conclusion of the fault judgment have subjective and human factors. And because there is dangerous high-voltage electricity in the electrified area of ​​the substation, the management personnel cannot enter the scene to observe and analyze the problem a...

[0002] Existing substation live area temperature monitoring systems generally have the following deficiencies: the existing technology is not intelligent enough, managers can only subjectively analyze and judge the operating temperature of substation live area equipment through a specific screen, and the monitoring system cannot make independent judgments Whether the equipment is overheated, which equipment is overheated, where is the specific space, and what is the reason for the overheating, which makes the fault judgment conclusion with subjective and human factors

And because there is dangerous high-voltage electricity in the electrified area of ​​the substation, the management personnel cannot enter the scene to observe and analyze the problem at the first time, so the golden time for troubleshooting is often missed; it is not accurate, and the existing technology can display the heat on a specific screen. Imaging map, but because the distance between each monitoring point and the camera is different, the monitoring effect is different. The effect of the long distance is relatively poor, and the effect of the short distance is relatively good, which leads to the farther the monitored temperature is, the more Inaccurate, this has little to do with the performance of the camera, it is related to the amount of infrared light entering the lens, so the temperature marked by the system is not necessarily the actual temperature of the equipment, sometimes the deviation is large, causing misjudgment by the management personnel; inconvenient: The existing technology must rely on fixed-position monitoring screens. Generally, the power supply bureau (or power bureau) that governs the substation is equipped with a monitoring center, and the monitoring screen of the system is configured in the monitoring center. The monitoring personnel obtain abnormal images and Alarm information, and then notify the management personnel of the substation. The management personnel may receive emails, or be notified by phone, or go to the monitoring center of the bureau to check the records. These cannot guarantee that the management personnel will obtain the most comprehensive, fastest and most intuitive information
