Description

Technical Field

[0001] This invention relates to the field of substation maintenance, and in particular to a method and apparatus for arranging safety measures in digital three-dimensional modeling of substations. Background Technology

[0002] With the significant improvement in electrification levels, substation loads are becoming increasingly heavy, leading to a surge in power outage maintenance tasks. During these outages, safety barriers are primarily used to isolate energized areas and ensure the safety of maintenance personnel. The installation of safety barriers is an extremely rigorous and complex task; even slight negligence can result in personnel injuries and equipment outages. Furthermore, due to the limitations of traditional safety barrier installations, it is difficult to isolate higher sections of energized equipment or equipment where the outage area and energized area are combined, thus failing to effectively guarantee the safety of maintenance personnel. When the outage area is large and there are many personnel, the person in charge cannot effectively supervise all personnel, and incidents of workers crossing, moving, or dismantling safety barriers frequently occur, posing serious safety hazards.

[0003] Traditional fence installation work involves one person directing multiple people to complete the work according to the work order requirements after a power outage, following the instructions of the maintenance duty officer. This process involves too many intermediate steps and is cumbersome, which can easily lead to problems such as unreasonable fence placement or omissions, posing certain safety hazards.

[0004] Moreover, traditional safety fences are mostly deployed in two dimensions. This leads to a situation where, during substation spring and autumn maintenance and large-scale power outages, there are many overlapping operations, complex maintenance sites, and a large number of personnel with diverse backgrounds. If the installation is unreliable, its isolation function will fail, potentially causing workers to accidentally enter energized areas, resulting in personal injury, equipment damage, and power grid outages.

[0020] S13, Point cloud data processing; First, the initial point cloud data and geographic location information data are processed by denoising and smoothing. Then, the spatial data collected from different sites are stitched together.

[0021] A high-precision 1:1 external structure model and internal equipment model are obtained, and after applying materials, a digital model is obtained.

[0022] S14, Point cloud data modeling; Based on different point cloud features, a three-dimensional spatial data model of the equipment is established; The 3D model of the substation is created using a geometric model.

[0023] Based on substation images, design drawings, and manufacturer equipment drawings, the geometric model uses professional software such as AutoCAD, 3ds Max, and Maya to create three-dimensional models of various electrical equipment in the substation according to a certain scale, using cubes, cylinders, cones, and tori. Then, the model textures and materials are set, and the electrical equipment models are spliced ​​together to complete the three-dimensional field modeling of the substation.

[0024] S15. Texture mapping: Mapping the textures collected on-site onto the 3D model to form the model's realistic texture.

[0025] This invention provides a 3D substation model that accurately and realistically recreates the substation site.
