Description

Technical Field

[0001] The present invention relates to the field of power management, and in particular to a substation. Background Art

[0002] A substation is a place in the power system where voltage and current are transformed, electric energy is received and distributed. The substation in a power plant is a step-up substation, and its function is to step up the electric energy generated by the generator and feed it into the high-voltage power grid. The electrical equipment in the substation is divided into primary equipment and secondary equipment. Primary equipment refers to equipment that directly produces, transmits, distributes and uses electric energy, mainly including transformers, high-voltage circuit breakers, disconnectors, busbars, lightning arresters, capacitors, reactors, etc. Secondary equipment refers to equipment that measures, monitors, controls and protects the operating conditions of primary equipment and systems. It mainly consists of relay protection systems, automatic systems, measurement and control systems, metering systems, automation systems and DC equipment that provides power to secondary equipment.

[0003] In order to facilitate power transmission, some substations are set up in places with dense traffic. However, substations have high safety requirements, especially high-voltage substations. Places with dense traffic will inevitably bring busy traffic and pedestrian flow, posing hidden dangers to the safety of substations. For example, if a human target wearing acrylic clothing gets too close to a high-voltage substation, there is a certain fire risk. Summary of the invention

[0004] In order to solve the technical problems in related fields, the present invention provides a substation, which can use a targeted visual recognition mechanism to intelligently identify whether there are people wearing acrylic clothes in the traffic area where the substation is located, and when the intelligent identification exists, execute a voice alarm operation to remind the people to stay away. What is particularly critical is that a visual processing mode is adopted in which the latest background picture is subtracted from the latest received spatial enhancement image to obtain the corresponding difference picture to ensure the reliability and effectiveness of the visual recognition result.

[0005] According to the present invention, a substation is provided, comprising a substation body and an environment directional monitoring and alarm system connected to the substation body, wherein the environment directional monitoring and alarm system comprises: The monitoring actuator is arranged on the wall of the substation, and is used to perform photoelectric sensing action on the traffic environment outside the wall at set intervals to obtain and output corresponding monitoring sensing images; A combined filtering device is arranged in a control room inside the substation and connected to the monitoring actuator, and is used to perform combined filtering processing on the received image to obtain and output a corresponding combined filtered image; A sorting filter device, connected to the combined filtering device, for performing statistical sorting filtering processing on the received combined filtered image to obtain and output a corresponding sorting filtered image; A content enhancement device, connected to the sorting and filtering device, configured to perform image spatial domain enhancement processing on the received sorting and filtering image to obtain and output a corresponding spatial domain enhanced image; A primary analysis device is arranged in a control room inside the substation and connected to the content enhancement device, and is used to use the picture with the smallest mean square error of pixel values ​​among the received multiple frames of past spatial domain enhancement images as the latest background picture whenever a spatial domain enhancement image is received; A secondary analysis device, connected to the primary analysis device, for subtracting the latest background picture from the latest received spatial enhancement image to obtain a corresponding difference picture, and performing object detection processing in the difference picture to determine whether there is a human body wearing acrylic clothing; A voice alarm device is connected to the secondary analysis device and is used to perform a voice alarm operation to remind the user to stay away from the user when it is determined that a person wearing acrylic clothing exists in the difference image; The picture with the smallest mean square error of pixel values ​​among the received multiple frames of past spatial domain enhanced images is used as the latest background picture, which includes: for each frame, obtaining the mean square error of each pixel value corresponding to each pixel point of the picture as the mean square error of the pixel value corresponding to the picture; Among them, performing object detection processing in the difference image to determine whether there is a human body wearing acrylic clothes includes: identifying each human body imaging area in the difference image based on the reference contour corresponding to the human body, performing color imaging characteristics of the acrylic material on each human body imaging area, and determining that there is a human body wearing acrylic clothes when the analysis result determines that the color imaging characteristics of a certain human body imaging area match the color imaging characteristics of the acrylic material.

[0006] It can be seen that the present invention mainly has the following significant technical effects: Firstly, a targeted mean square error numerical comparison mode is used to determine the most reliable background image, and the latest received spatial enhancement image is subtracted from the most reliable background image to obtain the corresponding difference image, i.e., the foreground image. Object detection is performed in the foreground image to narrow the scope of object detection and improve the efficiency and speed of object detection. Secondly: subtract the latest background image from the latest received spatial enhancement image to obtain a corresponding difference image, perform object detection processing in the difference image to determine whether there is a human body wearing acrylic clothing, and when it is determined that there is a human body wearing acrylic clothing in the difference image, perform a voice alarm operation to remind the human body to stay away; Again: based on the reference contour corresponding to the human body, each human body imaging area in the difference image is identified, and the color imaging characteristics of the acrylic material are analyzed for each human body imaging area. When the analysis result determines that the color imaging characteristics of a certain human body imaging area match the color imaging characteristics of the acrylic material, it is determined that there is a human body wearing acrylic clothing.

[0007] The substation of the present invention is safe, reliable and stable in operation. Since a targeted visual recognition mechanism can be used to intelligently identify whether there are people wearing acrylic clothing in the traffic area where the substation is located, and when the intelligent recognition exists, a voice alarm operation to remind people to stay away is executed, and a visual processing mode of a customized difference image acquisition mechanism is used to ensure the reliability and effectiveness of the visual recognition results, thereby maintaining the safe operation of the substation.
