A method and device for automatic recognition of substation knife switch position indication

Abstract

The present invention provides a method and device for automatic identification of switch position indication of a substation knife gate position. The method comprises: collecting an original image of the switch position of the knife gate position to be identified through a camera device, and intercepting a part of the original image as a target image ; Analyze the HOG feature and / or HSV feature of the target image; According to the HOG feature and / or HSV feature, calculate the probability value that the knife gate switch position to be identified is in a closed state and the probability of being in an open state value; compare the probability value of the closed state with the probability value of the open state, and determine whether the switch position of the knife gate to be identified is in the closed state or the open state. Aiming at the particularity of the knife gate position and the image indicated by the switch position, the method and the device for automatic identification of the switch position indication of the substation knife gate position provided by the present invention can improve the detection accuracy and prevent false detection by extracting different features of the image, comprehensively analyzing and judging. situation, to achieve the purpose of accurate detection.

Description

technical field [0001] The invention relates to the field of state recognition of power transmission and transformation equipment, in particular to a method and device for automatic recognition of switch position indication of a switch in a substation. Background technique [0002] With social progress and economic development, the public has higher and higher requirements for power quality, which requires power providers to better monitor the power supply network and equipment, and the identification of indoor substation knife switch position indications is one of them. Important monitoring items. [0003] At present, there are mainly two ways to identify the switch position indication of the switch position of the indoor substation: manual inspection and image template matching detection. [0004] The method of manual inspection is that the substation staff go to the scene to identify. It goes without saying that this method is inefficient and cannot grasp the operation s...

Problems solved by technology

[0006] In order to solve the problem in the prior art that the identification accuracy of the switch position indication of the switch position in the indoor substation is not high, the present invention proposes a method and device that can accurately identify the switch position indication of the switch position in the indoor substation. The particularity of the image indicated by the switch position, by extracting different features of the image, comprehensive analysis and judgment, improve the accuracy of detection, prevent false detection, and achieve the purpose of accurate detection
