Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] Such as figure 1 Shown is the flow chart of the electrolyte leakage identification method for substation communication power battery electrolyte leakage. This method mainly includes four processing steps: image preprocessing and object recognition based on color features, image segmentation of object feature areas, RGB color features and grayscale features. Combined battery casing and positive and negative casing identification, and battery electrolyte leakage identification based on multi-feature criteria.

[0040] In order to identify the storage battery in the monitoring image, the image preprocessing and object recognition processing steps based on color features include:

[0041] (1) Carry out mean value filter processing to the original picture of the battery that obtains;

[0042] Mean filtering can remove uniform noise and Gaus...

Abstract

The invention discloses a method for identifying leakage of battery electrolyte in a communication power supply battery of a substation. The characteristic objects of the outer surface of the battery case and the positive and negative shell covers in the picture are identified according to the color features, and then the outer surface of the battery shell and the positive and negative shell covers in the picture are segmented. In the feature area, the method of combining RGB color features and grayscale features is used to identify the position of the outer surface of the battery case and the positive and negative cover in the picture, and finally according to the symmetrical features of the outer surface of the battery case and the positive and negative cover in the picture , to exclude other interferences, so as to judge whether there is electrolyte leakage on the outer surface of the substation communication power battery case and the positive and negative shell covers according to the RGB color eigenvalues ​​and grayscale eigenvalues ​​of the outer surface of the battery shell and the positive and negative shell covers. The method of the present invention has reliable anti-interference capability, can effectively avoid interference phenomena due to picture shaking, blurring, etc., and has high accuracy and practicability.

Description

technical field [0001] The invention relates to a method for identifying electrolyte leakage of a communication power storage battery of a substation, and belongs to the technical field of substation communication. Background technique [0002] Due to the large number of substations, the large number of battery packs to be maintained, the long discharge time, and the lack of maintenance personnel, a large amount of manpower and material resources are required to carry out maintenance work every year. Due to the limited operation and maintenance personnel and heavy work, most of the battery packs cannot be effectively maintained. The leakage of battery electrolyte seriously affects the safe and stable operation of the power grid. Therefore, automatic technical means are used to automatically identify the leakage of battery electrolyte in substation communication power supplies, so as to effectively improve the efficiency of inspection work, reduce the workload of personnel in...
