Abstract

The invention relates to a three-dimensional path-finding navigation method and system for a nuclear power plant. The three-dimensional path-finding navigation method for the nuclear power plant comprises the following steps: utilizing PDMS modeling to obtain a three-dimensional arrangement model of the nuclear power plant; constructing a three-dimensional virtual scene of the nuclear power plant according to the three-dimensional arrangement model of the nuclear power plant by using a Unity 3D virtual simulation engine, and in the three-dimensional virtual scene, dividing a plant by layers, and setting relay points in each layer so as to bake a navigation grid layer by layer; and in the three-dimensional virtual scene, positioning a target item input by a user, receiving a starting point and an ending point set by the user, carrying out path-finding calculation in the three-dimensional virtual scene based on the hierarchical navigation grid, and carrying out dynamic navigation demonstration of an optimal path according to a path-finding calculation result. By implementing the technical scheme of the invention, the user can quickly and accurately reach the target point, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to a three-dimensional pathfinding and navigation method and system for a nuclear power plant. Background technique [0002] With the introduction and development of digital and intelligent means in nuclear power projects and operating units, three-dimensional digital power plants with virtual simulation technology as the core have begun to be applied to nuclear power project construction and operation management. At present, all nuclear power projects are carrying out forward three-dimensional design. These forward digital design results and accumulated model data provide key data support for the subsequent construction and operation management of power plants. In particular, in the operation and management of power plants, 3D design data can be used to conduct a series of simulation deduction of process simulation, maintenance and other work in the virtual scene of 3D nuclear power pl...
