Substation work ticket safety measure integrity discrimination method based on visual identification

Abstract

The invention discloses a substation work ticket safety measure integrity discrimination method based on visual identification, and the method comprises the steps: converting a safety measure of a work ticket into a safety measure code group which can be recognized by a computer, and inputting the safety measure code group into a database of a monitoring server; numbering and check code setting are carried out on the on-site monitoring cameras; the monitoring camera collecting on-site safety measure information, adding camera codes to the collected information, and uploading the information toa database of the server; and the data platform of the server comparing the information acquired by the camera with the safety measure logic code to judge whether the field safety measures meet the requirements of the safety measures on the work ticket or not, and if the field safety measures do not meet the requirements, sending and pushing alarm information to a specified mailbox to remind a worker. A worker does not need to hold the work ticket by hand to check the work ticket on site through a manual check method, the labor cost is reduced, and all-day online monitoring of the camera is utilized to ensure that safety measures are effective at any time.

Description

technical field [0001] The invention relates to the technical field of machine vision recognition and power system data collection and analysis, in particular to a method for judging the integrity of substation work ticket safety measures based on vision recognition. Background technique [0002] At present, the maintenance work in domestic and foreign power systems needs to go through the maintenance procedures, and the operator and the maintenance personnel will check the safety measures as required before allowing the work to be carried out. The layout and verification of safety measures are mainly done by printing paper work According to the requirements on the face of the ticket, layout and inspection are carried out. Although some stations use surveillance cameras to monitor the work area, the function of the video system is only to collect video signals and pass them on to the staff, and use manual methods to judge the monitoring security. Whether the implementation o...

AI Technical Summary

Problems solved by technology

[0003] 1. The monitoring device is basically connected to a specific monitoring system by the contact of the secondary circuit through the monitoring circuit. If the device itself does not have a monitoring circuit, it cannot be monitored;

[0004] 2. The disadvantage of the monitoring device is that the collected signal is relatively single and the amount of signal is small, and the means are single

For example, it is only possible to monitor the position of circuit breakers with opening and closing auxiliary contacts and isolating switches, but the signs and meters hung on the equipment, as well as the safety barriers at the work site, etc., cannot be monitored without access to the monitoring system;

[0005] 3. The method of loop monitoring needs to involve the security of the information system of the secondary security. If the requirements of information security are not met, the loop of the access device cannot be allowed to monitor;

[0006] 4. The monitoring area is relatively rigid, and the safety measures for each job may be different. The old monitoring method is limited by on-site signal lines, circuits, equipment locations, power supplies, etc., making it difficult to do all-round monitoring
