[0002] With the development of the power grid operation mode towards intelligence, substation auxiliary monitoring devices have become a key technical means to ensure the safe and stable operation of the power grid. However, at present, the layout of cameras in substations mainly relies on two-dimensional design drawings and experience, which easily leads to unreasonable camera layout, such as excessive quantity, overlapping coverage, monitoring dead angles, and insufficient number of cameras in key areas, thus increasing the layout cost. In addition, the design based on two-dimensional drawings often fails to take into account the on-site situation by designers, which may affect the live safety of the substation during construction, resulting in a mismatch between the design and the actual site, and further causing potential safety hazards and waste of time and resources.

Description of the Drawings

[0046] To more clearly illustrate the technical solutions in the embodiments of the present invention, the following will briefly introduce the drawings required in the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention, and those of ordinary skill in the art can obtain other drawings based on these drawings without creative efforts.

[0047] Figure 1 It is a flowchart of a method for arranging cameras in a substation in an embodiment of the present invention.

[0048] Figure 2 It is a structural diagram of a device for arranging cameras in a substation in another embodiment of the present invention. Detailed Description of the Specific Embodiment

[0049] The detailed description of the drawings is intended to be an illustration of the current embodiments of the present invention, rather than representing the only form in which the present invention can be implemented. It should be understood that the same or equivalent functions can be completed by different embodiments intended to be included within the spirit and scope of the present invention.

[0050] Refer to Figure 1, an embodiment of the present invention provides a method for arranging cameras in a substation, including the following steps:

[0051] Step S10, initialize the three-dimensional digital twin scene of the substation, and load the inspection point data of substation equipment, non-arrangement area data, and arrangement rule data;

[0052] Specifically, a three-dimensional digital model of the substation is constructed, which is an exact replica of the real-world substation, called the "digital twin scene"; then, the device loads data such as the key equipment inspection points in the substation, areas where cameras are not allowed to be installed (such as high-voltage dangerous areas), and relevant rules for camera arrangement (such as installation height, angle restrictions, etc.) into this three-dimensional model; these data will provide important references and limiting conditions for subsequent camera arrangement.

[0053] Step S20, detect the arranged cameras dragged and interacted by the operator in the three-dimensional digital twin scene of the substation;

[0054] Specifically, the operator can instantiate the corresponding type of camera to a specific installation position in the three-dimensional digital twin scene by dragging in the three-dimensional digital twin scene. After the arrangement is completed, the operator can submit it for the device to verify and confirm. The device will detect and record the position and direction of the cameras arranged by the operator, providing data for subsequent verification and analysis.

[0055] Step S30, perform occlusion relationship verification and live safety verification on the arranged cameras according to the substation equipment inspection point data, non-arrangement area data, and arrangement rule data;

[0056] Specifically, two key verifications are performed on the cameras arranged by the operator using the previously loaded data: the occlusion relationship verification ensures that there are no obstacles within the camera's line of sight and can effectively monitor the target area; the live safety verification ensures that the camera installation position does not pose a safety risk to the live equipment in the substation and does not violate relevant safety regulations; the arrangement rule data refers to that the camera arrangement needs to meet the occlusion relationship requirements and live safety requirements.

[0057] Step S40, if the arranged cameras pass the occlusion relationship verification and live safety verification, then perform an optimal arrangement analysis to determine whether there is an optimal solution. If so, output the optimal solution; if not, end;

[0058] Specifically, if the deployed cameras pass the above two verifications, the device will further analyze whether the current deployment plan is an optimal plan, which includes evaluating factors such as camera coverage, monitoring effect, cost-benefit, etc. If there is a more optimal deployment plan, this plan will be output for the operator's reference; if the current plan is already the best, or there is no more optimal plan, the deployment process ends. This step helps to ensure that the finally adopted camera deployment plan is efficient and economical.

[0059] In summary, the method of this embodiment effectively assists the operator in deploying cameras in a simulated real environment by establishing a three-dimensional digital twin scene of the substation and integrating equipment inspection points, non-deployable areas, and deployment rule data; this method not only ensures the rationality and safety of camera deployment, avoiding coverage overlap, monitoring dead spots, and live electrical safety hazards, but also improves the operator's deployment accuracy and efficiency through intuitive drag-and-drop interaction. In addition, this method can automatically perform an optimal analysis of the deployment plan, helping the operator to discover and implement the best deployment plan, thus saving costs while ensuring all-round monitoring of the substation, reducing the waste of time and resources caused by the inconsistency between the design and the actual situation, and providing an efficient, safe, and economical solution for the construction of the intelligent power grid.

[0060] In some embodiments, the occlusion relationship verification includes:

[0061] Step S311, obtain the position coordinates of the deployed camera and the position coordinates of the inspection point corresponding to the deployed camera;

[0062] Specifically, determine the specific position coordinates of the camera deployed by the operator in the three-dimensional digital twin scene, and at the same time obtain the position coordinates of the inspection points that the camera needs to monitor (i.e., the key equipment or areas that need to be monitored in the substation). These coordinates are the basis for subsequent occlusion relationship verification.

[0063] Step S312, based on the three-dimensional image engine, emit a conical ray from the position of the deployed camera according to the deployed camera parameters; the conical camera represents the field of view of the deployed camera;

[0064] Specifically, using three-dimensional image engine technology, emit a conical ray from the position of the camera. This conical ray simulates the actual field of view of the camera, that is, the area that the camera can monitor. The shape and size of the conical ray depend on the parameters of the camera, such as the field of view (FOV).

[0065] Step S313, detect whether the conical ray collides with other objects. If there is a collision, it is determined that there is an occlusion between the deployed camera and the inspection point; if there is no collision, it is determined that there is no occlusion between the deployed camera and the inspection point;

[0066] Specifically, it is detected whether the emitted conical ray collides with any object (such as a wall, a device, a structural component, etc.) in the three-dimensional scene. If the conical ray collides with any object before reaching the inspection point, it is determined that there is an occlusion between the camera and the inspection point, which means that the camera cannot directly monitor the inspection point. If there is no collision, it is considered that there is no occlusion between the camera and the inspection point, and the field of view of the camera is clear and can effectively monitor the inspection point.

[0067] In some embodiments, the live safety verification includes:

[0068] Step S321, loading a live safety expansion model of substation equipment in the three-dimensional digital twin scene of the substation; the live safety expansion model refers to adding a virtual safety area around the equipment;

[0069] Specifically, a virtual safety expansion model is added to the live equipment in the three-dimensional digital twin scene. This model actually creates an additional safety area around the live equipment, and this area represents the dangerous range where the equipment may generate electric arcs or discharges. This safety area is larger than the actual size of the equipment to take into account potential safety risks.

[0070] Step S322, calculating the spatial relationship and distance between the deployed camera and the nearest live collision model;

[0071] Specifically, the spatial relationship and distance between the deployed camera and the safety expansion model of the nearest live equipment are calculated to determine whether the camera is located within the safety area of the live equipment and the specific distance between them.

[0072] Step S323, determining whether the deployed camera is within the safety expansion area of the nearest live collision model according to the spatial relationship;

[0073] Specifically, according to the spatial relationship and distance calculated in the previous step, it is determined whether the camera is located within the safety expansion area of the live equipment. If the camera is located within this safety expansion area, then it may be at risk of electric shock or arc flashover.

[0074] Step S324, if so, determining that the deployed camera affects the safety of the substation;

[0075] Specifically, if the camera is located within the safety expansion area, it is determined that the deployment position of the camera will affect the safe operation of the substation because it may be at risk of electric shock or arc injury.

[0076] Step S325, if not, further determine whether the distance is less than a preset safety value. If so, it is determined that installing the camera affects the safety of the substation. If not, it is determined that installing the camera does not affect the safety of the substation;

[0077] Specifically, if the camera is not within the safe expansion area, the distance between the camera and the live equipment will be further checked to see if it is less than a preset safety value. If this distance is less than the safety value, even if the camera is not within the safe area, there may still be safety risks, so it is determined that the camera affects the safety of the substation; if the distance is greater than or equal to the preset safety value, it is considered that the installation of the camera will not affect the safe operation of the substation.

[0078] In some embodiments, the optimal layout analysis includes:

[0079] Analyze the coverage area of each installed camera, identify the monitoring overlapping areas, and determine whether there are cameras whose installed positions can be combined based on the monitoring overlapping areas. If so, perform the combination to reduce the number of installed cameras.

[0080] Specifically, the device will evaluate the monitoring field of view of each camera to determine its coverage area in the 3D digital twin scenario. The device checks the overlapping parts between the monitoring fields of view of different cameras, and these areas are defined as the monitoring overlapping areas. The device analyzes these overlapping areas to determine whether it is possible to reduce the monitoring overlap by adjusting the position or direction of the cameras, or removing some cameras, while maintaining effective monitoring of all key inspection points; if so, perform the combination to reduce the number of installed cameras: if it is determined that the monitoring areas can be combined, the device will propose a combination plan to reduce the overall number of installed cameras by adjusting or removing some cameras, thereby optimizing the layout plan.

[0081] Further, when combining the monitoring areas and performing the optimal layout analysis, factors such as the weight of the inspection points, the performance and cost of the cameras, and the ambient light can also be considered; according to the operation requirements and safety management regulations of the substation, a weight value is assigned to each inspection point, and this value reflects the importance of the point. For example, key equipment or high-risk areas will be assigned a higher weight. When installing cameras, priority is given to ensuring full coverage of the high-weight inspection points to ensure no blind spots in monitoring.

[0082] Specifically, in a three-dimensional digital twin scenario, all key points to be monitored are marked according to the weights of the inspection points; cameras are preferentially deployed according to the point weights to ensure that all high-weight points are effectively covered; for each point, a suitable camera model is selected according to its weight and the lighting conditions in the area; the cost-benefit ratio of each camera is calculated, and cameras with high cost performance are preferably selected; according to the weights of the inspection points and the lighting conditions of the location environment, a suitable camera is selected for it. For example, for inspection points with higher weights or poor lighting conditions in the location environment, higher performance requirements are imposed on the cameras, so the corresponding cameras should be those with better performance and higher costs to ensure the monitoring quality; for inspection points with lower weights or good lighting conditions in the location environment, lower performance requirements are imposed on the cameras, and the corresponding cameras should be those with relatively lower performance and lower costs to save costs.

[0083] Refer to Figure 2 , another embodiment of the present invention further provides a camera deployment device for a substation, including:

[0084] A scenario initialization module 1, configured to initialize the three-dimensional digital twin scenario of the substation and load the inspection point data of the substation equipment, the data of the non-deployable areas, and the deployment rule data;

[0085] A deployment detection module 2, configured to detect the cameras deployed by the operator in the three-dimensional digital twin scenario of the substation through a drag-and-drop interaction method;

[0086] A deployment verification module 3, configured to perform occlusion relationship verification and live wire safety verification on the deployed cameras according to the inspection point data of the substation equipment, the data of the non-deployable areas, and the deployment rule data;

[0087] A deployment optimization analysis module 4, configured to perform deployment optimization analysis if the deployed cameras pass the occlusion relationship verification and live wire safety verification, determine whether there is an optimal solution, and if so, output the optimal solution, and if not, end.

[0088] In some embodiments, the deployment verification module includes an occlusion relationship verification module;

[0089] The occlusion relationship verification module is configured to:

[0090] Obtain the position coordinates of the deployed cameras and the position coordinates of the inspection points corresponding to the deployed cameras;

[0091] Based on a three-dimensional image engine, emit conical rays from the positions of the deployed cameras according to the parameters of the deployed cameras; the conical camera represents the field of view of the deployed cameras;

[0092] Detect whether the conical ray collides with other objects. If there is a collision, it is determined that there is an occlusion between the installed camera and the inspection point. If there is no collision, it is determined that there is no occlusion between the installed camera and the inspection point.

[0093] In some embodiments, the installation verification module includes a live safety verification module;

[0094] The live safety verification module is used for:

[0095] Load a live safety expansion model of substation equipment in the 3D digital twin scene of the substation; the live safety expansion model refers to adding a virtual safety area around the equipment;

[0096] Calculate the spatial relationship and distance between the installed camera and the nearest live collision model;

[0097] Determine whether the installed camera is within the safety expansion area of the nearest live collision model according to the spatial relationship;

[0098] If so, it is determined that the installed camera affects the safety of the substation;

[0099] If not, further determine whether the distance is less than a preset safety value. If so, it is determined that the installed camera affects the safety of the substation. If not, it is determined that the installed camera does not affect the safety of the substation.

[0100] In some embodiments, the installation optimization analysis module is used to analyze the coverage range of each installed camera, identify the monitoring overlapping area, and determine whether there is an installed camera in the monitoring overlapping area that can merge the monitoring area. If so, merge them to reduce the number of installed cameras.

[0101] Furthermore, when merging the monitoring area, when the installation optimization analysis module performs the optimization analysis, it can also consider factors such as the weight of the inspection point, the performance and cost of the camera, and the environmental illumination; according to the operation requirements and safety management regulations of the substation, a weight value is assigned to each inspection point, and this value reflects the importance of the point. For example, key equipment or high-risk areas will be assigned a higher weight. When installing cameras, give priority to ensuring full coverage of high-weight inspection points to ensure no dead spots in monitoring.

[0102] Specifically, in the 3D digital twin scenario, the optimal layout analysis module marks all key points to be monitored according to the weights of inspection points; gives priority to the layout of cameras according to the point weights to ensure that all high-weight points are effectively covered; for each point, selects a suitable camera model according to its weight and the lighting conditions in the area; calculates the cost-benefit ratio of each camera and tries to select a camera with high cost performance; selects a suitable camera for the inspection point according to its weight and the lighting conditions of the location environment. For example, for inspection points with higher weights or poor lighting conditions in the location environment, higher performance requirements are imposed on the camera, so a camera with better performance and higher cost should be selected to ensure the monitoring quality; for inspection points with lower weights or good lighting conditions in the location environment, lower performance requirements are imposed on the camera, and a camera with relatively lower performance and lower cost should be selected to save costs.
