Description

Technical Field

[0001] This invention relates to the field of power management, and more particularly to a substation. Background Technology

[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of electrical energy generated by generators before feeding it into the high-voltage power grid. Electrical equipment within a substation is divided into primary and secondary equipment. Primary equipment refers to equipment that directly produces, transmits, distributes, and uses electrical energy, mainly including transformers, high-voltage circuit breakers, disconnect switches, busbars, surge arresters, capacitors, and reactors. 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 the secondary equipment.

[0003] For convenient power transmission, some substations are located in areas with high traffic volume. However, substations have high safety requirements, especially high-voltage substations. Areas with high traffic volume inevitably bring busy traffic and pedestrian flow, which poses potential safety hazards to substations. For example, if a person wearing acrylic clothing gets too close to a high-voltage substation, there is a certain risk of fire. Summary of the Invention

[0004] To address the technical challenges in this field, the present invention provides a substation capable of employing a targeted visual recognition mechanism to intelligently identify the presence of individuals wearing acrylic clothing in the traffic area where the substation is located. Upon detection, the substation triggers a voice alarm to alert the user to move away from the person. Crucially, the invention utilizes a visual processing mode that subtracts the latest background image from the latest received spatial enhancement image to obtain the corresponding difference image, thereby ensuring the reliability and effectiveness of the visual recognition results.

[0005] According to the present invention, a substation is provided, including a substation body and an environmental directional monitoring and alarm system connected to the substation body, the environmental directional monitoring and alarm system comprising:

[0006] The monitoring actuator is installed on the wall of the substation perimeter wall. It is used to perform photoelectric sensing actions on the traffic environment outside the wall at set intervals to obtain and output the corresponding monitoring and sensing images.

[0007] A combined filtering device is installed in the control room inside the substation and connected to the monitoring execution mechanism. It is used to perform combined filtering processing on the received image to obtain and output the corresponding combined filtered image.

[0008] A sorting filter device, connected to the combined filter device, is used to perform statistical sorting filter processing on the received combined filter image to obtain and output the corresponding sorting filter image.

[0009] A content enhancement device, connected to the sorting and filtering device, is used to perform image spatial domain enhancement processing on the received sorting and filtering image to obtain and output a corresponding spatial domain enhanced image;

[0010] The primary analysis device, located in the control room inside the substation and connected to the content enhancement device, is used to select the image with the smallest mean square error of pixel values ​​among the multiple previously received spatial enhancement images as the latest background image each time a spatial enhancement image is received.

[0011] The secondary analysis device, connected to the primary analysis device, is used to subtract the latest background image from the latest received spatial enhancement image to obtain a corresponding difference image, and to perform object detection processing in the difference image to determine whether there is a human body wearing acrylic clothing.

[0012] A voice alarm device, connected to the secondary analysis device, is used to perform a voice alarm operation to remind the human body to move away when the presence of a human body wearing acrylic clothing is determined in the difference screen.

[0013] Among them, the image with the smallest mean square error of pixel value among the received multiple frames of spatial enhancement images is used as the latest background image. This includes: for each frame, obtaining the mean square error of each pixel value corresponding to each component pixel of the image as the mean square error of pixel value corresponding to the image.

[0014] The process of performing object detection processing in the difference image to determine whether there is a human body wearing acrylic clothing includes: identifying each human body imaging region in the difference image based on the reference contour corresponding to the human body, performing color imaging feature analysis of acrylic material on each human body imaging region, and determining that there is a human body wearing acrylic clothing when the analysis results determine that the color imaging feature of a certain human body imaging region matches the color imaging feature of acrylic material.

[0015] Therefore, it can be seen that the present invention has the following significant technical effects:

[0016] First, a targeted mean square error numerical comparison mode is used to determine the most reliable background image. The latest received spatial enhancement image is then subtracted from the most reliable background image to obtain the corresponding difference image, i.e., the foreground image. Object detection is then performed in the foreground image to narrow down the object detection range and improve the efficiency and speed of object detection.

[0017] Secondly: Subtract the latest background image from the latest received spatial enhancement image to obtain the corresponding difference image. Perform object detection processing in the difference image to determine whether there is a human body wearing acrylic clothing. 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 move away.

[0018] Again: Based on the baseline contour recognition difference image of the human body, analyze the color imaging characteristics of acrylic material for each human body imaging area, and determine the existence of a human body wearing acrylic clothing when the analysis results determine that the color imaging characteristics of a certain human body imaging area match the color imaging characteristics of acrylic material.

[0019] The substation of this invention is safe, reliable, and operates stably. It employs a targeted visual recognition mechanism to intelligently identify the presence of people wearing acrylic clothing in the traffic area where the substation is located. When a person is detected, a voice alarm is triggered to alert the substation to move away. Furthermore, a customized differential image acquisition mechanism is used in the visual processing mode to ensure the reliability and effectiveness of the visual recognition results, thereby maintaining the safe operation of the substation.
