Abstract

The invention provides a state identification method and device of a hard press plate and electronic equipment. The state identification method and device of the hard press plate and the electronic equipment are suitable for the power field. The method comprises: receiving an image, which is collected by a photographing module, of the hard press plate; segmenting the image, which is collected by the photographing module, of the hard press plate on the basis of a GrabCut algorithm to obtain an image used for identifying a state of the hard press plate; screening out an area, which matches data in a sample data histogram, from the image used for identifying the state of the hard press plate, and carrying out binaryzation on the area to obtain a binary image; utilizing a min heap algorithm to obtain positions of upper and lower connection points of switches of the hard press plate according to the binary image; and identifying whether the number of non-zero pixel points at centers of the connection points exceeds a preset threshold value, if yes, determining that the hard press plate is in a closure state, and otherwise, determining that the hard press plate in a disconnection state. The state identification method of the hard press plate of the invention is high in an accuracy rate and good in detection effect, can effectively monitor the state of the hard press plate and save manpower resources, and has a very high application value.

Description

Technical field [0001] The invention belongs to the field of electric power, and in particular relates to a method, device and electronic equipment for identifying the state of a hard press plate. Background technique [0002] At present, with the continuous advancement of smart grids, the construction of smart substations has entered a stage of rapid development, and the safe operation of station equipment is becoming more and more important. In order to ensure the safe operation of power secondary equipment, it is necessary to monitor the relevant status of the power secondary equipment in the station. Power secondary equipment is an auxiliary equipment that monitors, measures, controls, protects, and regulates primary equipment in the power system, that is, equipment that is not directly connected with electrical energy. In recent years, with the development of image processing technology, image recognition technology has been applied in the state monitoring of power systems:...
