Description

Technical Field

[0001] The invention relates to the field of monitoring, and in particular to a directional shielding system for improving the safety and stability of a substation. Background Art

[0002] Substation inspection is a process where the on-duty personnel regularly inspect and observe the appearance of the equipment for any abnormalities, such as color changes, debris, whether the needle indication is normal, whether the sound of the equipment is normal, whether there is any abnormal smell, whether the temperature of the equipment that can be touched is normal, and measure the changes in the operating parameters of the electrical equipment during operation, etc., to determine whether the equipment is operating normally. The inspection system of substations is an effective measure to ensure the normal and safe operation of equipment. It is of great significance to understand the equipment operating status, grasp the abnormal operation, and take corresponding measures in a timely manner through regular inspections by on-duty personnel, which is of great significance to reducing the occurrence of accidents and their scope of impact.

[0003] However, for substations located near traffic roads, not only internal security inspections are required, but also if there are electric vehicles on the road too close to the substation, the battery packs and other electrical equipment of the electric vehicles may cause electromagnetic interference to the substation, thereby affecting the normal operation of various power equipment inside the substation. Therefore, it is also necessary to control the presence of electric vehicles on the road too close to the substation and take countermeasures when electric vehicles are present. Obviously, the above technical content is not involved in the existing technology. Summary of the invention

[0004] In order to overcome the technical problems in the prior art, the present invention proposes a directional shielding system for improving the safety and stability of substations. The system can perform target detection processing in the interpolation image based on the corresponding appearance imaging characteristics of the electric vehicle to determine whether there is an electric vehicle on the basis of targeted interpolation image analysis, and when the existence of the electric vehicle is determined in the interpolation image, perform electromagnetic shielding operations on the side of the substation close to the traffic road near the substation, thereby taking into account both the electromagnetic shielding effect and the on-site monitoring field of view.

[0005] According to the present invention, a directional shielding system for improving the safety and stability of a substation is provided, the system comprising:

[0006] An information sensing device is arranged on the roadside of a traffic road near a substation, and is used to sense an audio signal of a scene where the traffic road is located in real time, and to issue a first trigger instruction when the signal amplitude of the audio signal obtained by real-time sensing exceeds a limit, and to issue a second trigger instruction when the signal amplitude of the audio signal obtained by real-time sensing does not exceed a limit;

[0009] An image recognition mechanism is connected to the layer-by-layer conversion device and includes a mean square error parsing unit, a difference processing unit and a target identification unit. The interpolation processing unit is connected to the mean square error parsing unit and the target identification unit, respectively. The image recognition mechanism is used to, when receiving each image to be processed, use the image with the smallest mean square error value of pixel values ​​among the received multiple frames of past images to be processed as the latest background image, subtract the latest background image from the latest received image to be processed to obtain a corresponding difference image, and perform target detection processing in the interpolation image to determine whether there is an electric vehicle, wherein the subtracting the latest background image from the latest received image to be processed to obtain a corresponding difference image, and performing target detection processing in the interpolation image to determine whether there is an electric vehicle includes: performing target detection processing in the interpolation image based on the corresponding appearance imaging characteristics of the electric vehicle to determine whether there is an electric vehicle;

[0011] Among them, when it is determined that there is an electric vehicle in the interpolation image, an electromagnetic shielding operation is performed on the side of the substation close to the traffic road near the substation, otherwise, the electromagnetic shielding operation on the side of the substation close to the traffic road near the substation is ended, including: performing the electromagnetic shielding operation on the side of the substation close to the traffic road near the substation in a mode of raising the electromagnetic shielding plate on the side of the traffic road near the substation.

[0012] It can be seen that the present invention has at least the following two important invention points:

[0013] Invention point (1): when each image to be processed is received, the image with the smallest mean square error of pixel values ​​among the received multiple frames of past images to be processed is used as the latest background image, the latest background image is subtracted from the latest received image to be processed to obtain a corresponding difference image, and target detection processing is performed in the interpolated image to determine whether a target exists, wherein the image with the smallest mean square error of pixel values ​​among the received multiple frames of past images to be processed is used as the latest background image, including: for each frame of the image, obtaining the mean square error of each pixel value corresponding to each pixel point of the image as the mean square error of the pixel value corresponding to the image;

[0014] Inventive point (2): performing target detection processing in the interpolated image based on the appearance imaging characteristics corresponding to the electric vehicle to determine whether there is an electric vehicle;

[0015] Invention point (3): When it is determined that an electric vehicle exists in the interpolation image, an electromagnetic shielding operation is performed on the side of the substation close to the traffic road near the substation, otherwise, the electromagnetic shielding operation on the side of the substation close to the traffic road near the substation is terminated, wherein the electromagnetic shielding operation on the side of the substation close to the traffic road near the substation is performed in a mode of raising the electromagnetic shielding plate on the side of the traffic road near the substation, thereby taking into account both the electromagnetic shielding effect and the on-site monitoring field of view.

Since it can perform target detection processing in the interpolation image based on the appearance imaging characteristics corresponding to the electric vehicle on the basis of targeted interpolation image analysis to determine whether there is an electric vehicle, and when it is determined that there is an electric vehicle, perform electromagnetic shielding operation on the side of the substation close to the traffic road near the substation, thereby improving the safety and stability of the substation near the traffic road.
