Problems solved by technology

However, due to corrosion, wear, aging and other reasons, the auxiliary switch cannot be switched in place, and sometimes the real position of the switch cannot be correctly judged, which provides wrong information for dispatching and commanding
At this time, it is necessary to manually go to the site for on-the-spot observation, and it generally takes a long time to troubleshoot, which brings unsafe factors to the grid power supply, and even requires power outages for maintenance.

Embodiment Construction

[0016] The invention provides an image processing and recognition method for real-time monitoring of switch states of electric high-voltage circuit breakers. This method is to combine remote digital video monitoring with image recognition system, and transmit the collected digital video signal back to the monitoring center in real time in the form of video stream through the transmission channel through the camera, decoder, video server and other equipment. Carry out remote video surveillance on site, intercept surveillance target pictures from video streams, and analyze, process and identify digital video images through corresponding image preprocessing techniques. The specific methods are as follows.

[0017] 1. Using the method of color feature matching, according to the different background colors of ON / OFF switches, extract the color features of the background color area as the basis for identification. If the background color is red, it will be judged as "ON", if the back...

Abstract

The disclosed image processing and recognition method for real-time monitor on power high-voltage circuit breaker comprises: with camera, decoder and video server, sending acquired signal to monitor center for remote video monitor; extracting target picture to recognize the ON / OFF state by sorting match with color and character structure features for fault analysis with accuracy ratio more than 98%. This invention can improve information level for power system.

Description

technical field [0001] The invention belongs to the technical field of remote digital video monitoring and image recognition, and the ON / OFF state monitoring of an electric high-voltage circuit breaker switch. Specifically, it involves the application of image grayscale, binarization, and normalized image preprocessing technology to perform automatic image recognition and fault alarm on the ON / OFF state of the switch of the high-voltage circuit breaker. Image processing and recognition methods for monitoring. Background technique [0002] In the process of power dispatching, the state and position of the switch are mainly judged according to the auxiliary node of the circuit breaker. However, due to corrosion, wear, aging and other reasons, the switching of the auxiliary switch is not in place, and sometimes the real position of the switch cannot be correctly judged, which provides wrong information for dispatching and commanding. At this time, it is necessary to manually ...
