Abstract

The invention discloses an intelligent identification apparatus of the switching plate of an embedded electric power relay pressure plate and a realization method. The intelligent identification apparatus comprises pressure plate image marking and recognizer training parts and embedded image acquisition and processing identification parts, and the pressure plate image marking and recognizer training parts and the embedded image acquisition and processing identification parts switch data through a wired / wireless network. The method is represented in the image acquisition and processing identification parts and includes: firstly, loading a trained pressure plate detection and pressure plate state identification model; then acquiring an image of the relay pressure plate by employing a camera, performing noise reduction, smooth, and illumination uniform processing on the image, and detecting the position of the pressure plate by employing a pressure plate detector; identifying each detected area to determine the state of the pressure plate; and finally, determining the final state of the pressure plate and checking the final state and the previous state through determination of a prior rule, outputting a checking result, and saving the result through a local storage module.

Description

technical field [0001] The invention relates to an intelligent image recognition technology, in particular to a power relay voltage board using image recognition and machine learning technology to provide an embedded relay voltage board switching state intelligent recognition device and implementation method, belonging to image processing technology and power equipment technical field. Background technique [0002] The relay voltage board is the bridge and link between the relay protection device or the automatic device and the external wiring, which is related to the realization of the protection function and whether the action outlet can function normally. These pressure plates are generally installed in the protection cabinet of the substation. The opening and closing of the pressure plates on the relay protection screen determines the on-off of the circuit. This requires that the connection method of the pressure plates should be accurate, otherwise serious accidents wil...

AI Technical Summary

Problems solved by technology

The former method cannot know exactly whether the pressure plate is closed or open, and the difference between the two image shooting angles should not be too large; the latter method has high requirements on light and angle, and the detection accuracy is not very high

[0005] On the whole, the existing image-based recognition method for the switch-out state of the relay voltage board is sensitive to illumination changes and shooting angles, lacks robustness, and is difficult to apply to the actual system, and the traditional image is still used technically. The identification method does not use advanced machine learning technology, and at the same time, there is no report on the use of embedded systems for platen status identification
