The invention discloses an image identification method for an on-off indicating lamp of a high-voltage circuit breaker, relates to the technical field of power systems, and solves the technical problem of identifying the state of the on-off indicating lamp of the circuit breaker. The method comprises the following steps: firstly, acquiring an image when the on-off indicating lamp displays an opening state and an image when the on-off indicating lamp displays a closing state, and defining two images as reference images; and performing multi-value gray processing and gray fitting calculation onthe two reference images to obtain a pixel point gray average fitting value of each calibration block of the two reference images, and identifying the real-time image in the opening and closing identification area by using the pixel point gray average fitting value of each calibration block of the two reference images. The method provided by the invention is suitable for a substation configured with the high-voltage circuit breaker.
Description
technical field [0001] The invention relates to the technology of the power system, in particular to a technology of an image recognition method for the opening and closing indicator lights of a high-voltage circuit breaker. Background technique [0002] In the substation auxiliary monitoring system, it is often necessary to identify the circuit breaker indicator light in the video image to assist in judging the opening and closing time of the circuit breaker. From a single comprehensive automatic signal monitoring mode to a variety of signal mutual verification modes, This recognition of the image indicator light can improve the reliability of monitoring and the level of accident analysis. [0003] Most image recognition requires a large number of training samples to meet the multi-dimensional requirements of nonlinear recognition techniques. For substations that have just been put into use or have been renovated, too long training time and insufficient sample pictures wil...
