Intelligent power distribution room foreign matter monitoring method and device and storage medium

Abstract

The invention discloses an intelligent power distribution room foreign matter monitoring method and device and a storage medium. The method comprises the steps of obtaining a power distribution room digital video signal in a preset time period; cutting a target area image based on a preset electronic forbidden area according to the current frame image of the digital video signal; dynamically selecting a frame of image without foreign matters according to the digital video signal, and cutting out a background frame image based on a preset electronic forbidden zone; according to the target area image and the background frame image, whether foreign matters enter the electronic forbidden area is judged based on a background difference method; if the foreign matter enters the electronic forbidden zone, extracting a shape feature vector and a color feature vector of the foreign matter, and combining the shape feature vector and the color feature vector to generate a foreign matter feature vector; inputting the feature vectors of the foreign matters into a trained support vector machine for classification and recognition to obtain the types of the foreign matters; marking and displaying the digital video signal according to the type of the foreign matter and sending the digital video signal to a worker; according to the invention, when foreign matters intrude, judgment and timely reminding can be carried out, and the automation level of the power distribution room is improved.

Description

technical field [0001] The invention relates to a foreign object monitoring method, device and storage medium in an intelligent power distribution room, and belongs to the technical field of power distribution automation. Background technique [0002] The power distribution room is the main equipment place for the transmission and distribution of electric energy at the end of the power system, and is an important part of the urban power distribution network system. For a long time, the management of the power distribution room has always been the weak link in the reliability of the operation and management of the power supply system. The complex working environment is the difficulty in the management of the power distribution room. Trends in the development of housing management technology. [0003] As the "eyes" of the smart grid, the monitoring system is an important guarantee for maintaining the stable operation of the power grid. It records the natural environment in wh...

Problems solved by technology

At present, the safety management of the operation behavior in the power distribution room is still dominated by manual management. The security monitoring methods are relatively backward and the degree of automation is low. It mainly depends on the observation and judgment of workers. There are the following problems:

[0004] (1) The monitoring center receives the video data transmitted by each monitoring point, and the relevant staff conduct in-depth analysis. When the monitoring system is huge and the monitoring points are widely distributed, the workload of the staff is heavy; it is difficult for the staff to conduct video analysis for a long time Maintain a high degree of concentration, there is a high possibility of omission or misjudgment; the site environment of the power distribution room is complex, and sometimes small changes are difficult to attract visual attention, and the reliability of observation is not high

(2) Secondly, some power distribution room monitoring systems have certain image processing capabilities, but the methods adopted are relatively basic. Generally, only the grayscale features of the image are considered, and most of them use template matching recognition methods, and the recognition accuracy is not high. Poor generalization ability and weak anti-interference ability
