Method for analyzing targets entering substation environment

Abstract

The invention discloses an analysis method for targets entering a substation environment. The method comprises the following steps: an infrared sensing network is established around the substation, and the infrared sensing network surrounds the edge of a set area around the substation; constructing an infrared human behavior database, wherein a plurality of infrared human behavior templates are stored in the infrared human behavior database; The infrared sensing network performs infrared detection on the target entering the set area in real time, tracks the behavior of the target, and generates an infrared video image; and the infrared sensing network performs infrared detection on the target entering the set area in real time. Gaussian mixture model and background subtraction algorithm are adopted to extract the behavior spatio-temporal contour of the object in the infrared video image, and the behavior spatio-temporal contour of the object is enhanced in contrast. The behavior space-time contour of the target is compared with a plurality of infrared human behavior templates stored in the infrared human behavior database one by one, and similarity analysis is performed on the behavior space-time contour of the target and the infrared human behavior templates.

Description

technical field [0001] The invention relates to the technical field of substation target detection, in particular to an analysis method for targets entering the substation environment. Background technique [0002] The substation is the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. In order to ensure the quality of electric energy and the safety of equipment, voltage adjustment, power flow (flow direction and distribution of voltage, current and power in each node and branch in the power system) control and power transmission and distribution lines and Protection of major electrical equipment. Due to the improvement of equipment reliability, the main wiring and auxiliary facilities of substations are gradually simplified and typicalized, creating conditions for substations to be miniaturized, intelligent, occupying less land, and even building underground substations. The means of remote control an...

Problems solved by technology

[0003] The impact of the substation on the surrounding environment is that there is radiation within 300 meters, and there is a lot of noise. In order to avoid pedestrians entering the substation environment by mistake, an analysis method is needed for the target entering the substation environment. The existing monitoring requires the person on duty to directly look at the big screen To determine what the intruding foreign object is, it cannot be automatically identified, and it is easy to miss the observation when the monitoring personnel are negligent, which will bring unpredictable consequences
