Automatic detection method for state of isolating switch based on image intelligent recognition algorithm

Abstract

The invention discloses an automatic detection method for the state of an isolating switch based on an image intelligent recognition algorithm. Aiming at a visible on / off state of the isolating switch in an open substation, intelligent recognition of the on / off state of the isolating switch is realized by adopting the image intelligent recognition algorithm. The automatic detection method comprises the following steps: S1, acquisition and initial processing of pictures; S2, background modeling of the isolating switch; S3, training of an on-state sample and an off-state sample; S4, performing state recognition by using training results. Image recognition of the state of the isolating switch of the substation has important significance for state patrol of intelligent equipment of a power grid, alarming linkage of the equipment and other production operation monitoring of the power grid and has a certain promoting action for development and improvement on an intelligent level of the power grid.

Description

technical field [0001] The invention belongs to the field of intelligent analysis of substation images and the field of online monitoring of substation equipment status, and relates to technologies such as image processing and computers, in particular to a detection method based on an image intelligent recognition algorithm for judging the opening and closing state of substation isolating switch equipment. Background technique [0002] The video technology of the substation provides a technical means for remote monitoring of the visualization of the isolating switch and other equipment in the substation, and provides a basis for visual monitoring and auxiliary decision-making for the dispatching operation of the substation. With the continuous development of networked, high-definition, and intelligent technology of video surveillance, the application of video surveillance technology in power grid security and production operation is deepening and extensive.

Problems solved by technology

With the continuous development of networked, high-definition, and intelligent technology of video surveillance, the application of video surveillance technology in power grid security and production operation is deepening and extensive. The video surveillance technology used in traditional methods provides remote The visual monitoring method provides a reliable and effective confirmation method for remotely confirming whether the actual state of the equipment is consistent with the state displayed by the monitoring data, and provides a basis for making accurate decisions. However, with the continuous deepening and popularization of this technology , due to the large number of substations and the large number of equipment in the station, if the status check and confirmation of each equipment needs to be checked and confirmed manually, the workload will be particularly large and the work efficiency will be low. With the continuous improvement of intelligent level requirements, how to improve the application of video surveillance technology in grid intelligent monitoring technology will play a role in promoting the improvement of grid intelligent level
