Method for automatically identifying substation switchgear equipment object based on two-dimensional code

Abstract

The invention discloses a method for automatically identifying a substation switchgear equipment object based on a two-dimensional code, which identifies the switchgear equipment object by identifying a two-dimensional code label affixed to the switchgear using video analysis technology on the basis of the existing switch room video monitoring system. The method comprises the steps of S1: image acquisition and initialization processing; S2: positioning of the region of a two-dimensional code label in an image; S3: conversion of a deformed two-dimensional code image into a standard two-dimensional code image by image plane correction; and S4: two-dimensional code information reading and switchgear equipment object identification. Therefore, the invention proposes the method of automatically identifying a switchgear by identifying a two-dimensional code using a video intelligent analysis method, is of great significance to the production and operation monitoring of a power grid, and has a certain positive effect in enhancing the intelligent monitoring technology in the intelligent level of the power grid.

[0007] In view of the above-mentioned technical analysis of various existing technical solutions, the method based on template matching technology needs to be constructed first. The characteristic model of the switchgear equipment object, due to the different shooting angles of the substation video monitoring equipment, there are many occlusions between the equipment, Various factors such as weather, different camera resolution, and different lighting conditions make it difficult to match the constructed switchgear feature model in practical applications. It can only be used in laboratory tests and verifications. The practical application significance not big

The use of video intelligent recognition technology based on machine learning algorithms depends on the collection of a large number of switchgear equipment model samples. The comprehensiveness and accuracy of the collected model samples will directly affect the accuracy of the equipment model constructed by machine learning. Affecting the accuracy of video recognition, the workload is heavy, and the sample library and machine learning algorithms need to be continuously optimized and adjusted. Moreover, since the scene of substation video surveillance usually contains many devices, it will greatly affect the accuracy and accuracy of video recognition. Reliability. At the same time, the above two methods can only identify the type of switchgear equipment, but cannot specifically identify the name of the switchgear equipment. It is difficult to meet the needs of the identification of the state of the switchgear equipment during production and operation.

[0008] The traditional method of manually setting the preset position to identify the switchgear needs to reset the preset position every time the position of the switchgear is changed, which wastes human resources

At the same time, the detailed information of the switchgear, such as the name and model of the switchgear, cannot be obtained only through video monitoring of the switchgear

Due to the large number of switch cabinets in the substation and the different voltage levels of the equipment, although there is monitoring, it is still necessary to manually confirm the specific information of the switch cabinets. Therefore, the traditional monitoring system has very little effect on identifying the switch cabinets
