A modeling method for the construction and deployment of substation monitoring cameras

Abstract

The invention discloses a substation site monitoring camera constructing, deploying and modeling method. The method comprises the following steps: 1) constructing a three-dimensional information scene of a substation through identifying the two-dimensional drawing information of the substation; 2) setting a simulative camera point location in the three-dimensional scene; and 3) determining the installation site information and height information of the camera installed in the substation through three-dimensional space point location visual computing. According to the method, the practical design drawings of substation devices are adopted, the data such as installation positions and installation heights of the devices on the scene is analyzed according to the names of the devices, and automatic design modeling of the installation position and installation height of the substation camera is realized through a simple three-dimensional model; and the method is labor-saving and simple to operate; the automatic design modeling can be carried out according to the provided substation device design plane drawings, so that the method has wide adaptation, is not influenced by the differences of different substations, and has a certain promotion function in the development and improvement of the power grid intelligence level.

Description

technical field [0001] The invention belongs to the technical field of substation construction, and in particular relates to a modeling method for construction and deployment of substation site monitoring cameras. Background technique [0002] The traditional substation video surveillance system is mainly used in the security monitoring of substations. Its installation location is relatively fixed, and it is mainly installed at the perimeter and entrance of the substation to realize the security monitoring of the substation. With the continuous promotion of unattended substations and smart substations in the power grid, video technology has not only been applied to security monitoring needs, but remote video monitoring has gradually provided more reliable and objective on-site equipment operating status for equipment monitoring of power grid production and operation. Remote visual monitoring of the power grid and auxiliary decision-making for production and operation provide...

Problems solved by technology

However, due to the complexity of the scene in the substation and the large number and types of equipment in production and operation, how to reasonably design and install the position of the camera will directly determine the role that video surveillance technology can play in the production and operation of the power grid. At present, the installation design of the camera At present, it still stays in the guiding specification, and only puts forward general requirements for the installation position. Regarding how to realize the requirements, each construction manufacturer only designs and installs the installation position and height of the camera according to the convenience of on-site installation and the way of manual subjective judgment. , but the actual monitoring effect after installation is not good; in addition, some substations are installed in a way of one-to-one correspondence between equipment and monitoring cameras. Although this method meets the needs of equipment monitoring, the number of cameras in this method is quite large. As a result, the monitoring cost, maintenance workload and cost are particularly high, and the practicability and scalability are poor; in addition, some substations use 3D modeling to design the installation position and height of substation cameras, so as to construct accurate Camera installation design, this method has a better monitoring effect, and the construction cost has been significantly reduced compared with the previous method. However, this solution needs to manually model the substation through 3D modeling, which has a large workload The models of each substation are inconsistent and need to be modeled separately, resulting in the lack of versatility of the 3D model of the substation and the need for independent modeling, resulting in poor technical scalability of this method
