A method and system for three-dimensional path planning of a nuclear engineering plant, and an electronic device

Abstract

This invention provides a three-dimensional path planning method, system, and electronic equipment for nuclear engineering plant buildings, belonging to the field of nuclear engineering radiation protection technology. The method includes: discretizing the three-dimensional geometric model of the nuclear engineering plant building into multiple voxels, and labeling each voxel with a radiation dose rate value based on radiation field data; labeling each voxel with the traversability results corresponding to the M protection levels according to preset geometric constraint parameters and radiation constraint parameters, obtaining a multi-level traversability voxel map; generating navigation meshes corresponding one-to-one with each protection level; receiving path planning requests; loading the corresponding navigation meshes according to the requests; and running an improved heuristic search algorithm on the loaded navigation meshes to search for the optimal three-dimensional path from the starting point to the destination. This method addresses the problem in related technologies where path planning fails to adequately consider radiation safety and does not match the safety requirements of protection levels.
