Construction positioning display method and construction positioning display system based on geographic information of nuclear power plant

Abstract

The invention discloses a construction positioning display method and a construction positioning display system based on geographic information of a nuclear power plant. The method includes: S1, creating a virtual three-dimensional model of an area below the surface of a preset area according to actual data of the area below the preset area; S2, in the preset area, creating a three-dimensional model of a digging area of a pre-digging project; S3, combining the virtual three-dimensional model with the three-dimensional model of the digging area to perform collision analysis and output and display an analysis result. The construction positioning display method and the construction positioning display system have the advantages through three-dimensional virtual restoration display of a scene of a nuclear power plant site, the digging area is positioned through geographical coordinates by a three-dimensional positioning function and space positions and trends of surrounding underground facilities are checked all-directionally; collision conditions of the digging area and the underground facilities are analyzed timely by the aid of a three-dimensional analyzing function; the underground facilities of the nuclear power plant site are visualized, professional requirements of professional engineers are lowered, analysis steps and time of the digging area are reduced, damage rate of the underground facilities is reduced, and construction efficiency of the nuclear power plant site is improved.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a construction location display method and system based on geographical information of nuclear power plants. Background technique [0002] In the construction process of nuclear power plant site engineering, land excavation and ground-breaking operations are carried out throughout. An intricate network of underground facilities consisting of various cables and pipelines will be laid underground in the nuclear power plant. These underground facilities are the basis for the construction of the nuclear power plant site. Excavation operations in the plant site may lead to damage to underground facilities at any time, resulting in the inability to work or construct in some areas of the construction site, thereby affecting the construction period of the entire nuclear power plant site. Due to the invisibility of various underground facilities in the ground-breaking area, there h...
