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

Embodiment Construction
[0032] The various details involved in the technical method of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.
[0033] In this embodiment, a video intelligent analysis method for line segment fitting of a substation isolating switch aims at the visible opening and closing state of the isolating switch in an open substation, and adopts a video intelligent analysis method based on line segment fitting to realize its opening and closing state. Intelligent identification, the steps are as follows: obtain the real-time video of the substation monitoring camera remotely, and obtain a certain frame of image data in the real-time video, convert the frame of image data into a data format that can be processed; After smoothing preprocessing, the edge of the image is ...

The invention discloses a video intelligent analysis method for substation isolating switch line segment fitting. After the smooth preprocessing of the gradient value, the edge of the image is extracted through the image binarization processing to form a binarized image of the image; Fitting is performed, and the slope of all fitted line segments is calculated to determine whether it is a valid line segment; if it is an interfering line segment, the line segment is excluded; the obtained effective line segment is projected, and the pixel duty ratio of the line segment in the projection direction is calculated. Obtain the duty cycle of the connected area, and finally judge the opening and closing state of the isolating switch. The image recognition of the present invention is of great significance for the production and operation monitoring of the power grid, and has a certain role in promoting the development and improvement of the intelligent level of the power grid.
Description
