System and method for realizing nuclear plant three-dimensional digital map

Abstract

The invention provides a system for realizing a nuclear plant three-dimensional digital map. The system comprises a virtual reality simulation module, a model rendering optimization module, a path planning algorithm implementation module, a path planning analysis module, a simulated figure walking control module, a path node arrangement module and an external data storage database. According to the system and method for realizing the nuclear plant three-dimensional digital map, through use of a nuclear power three-dimensional design model and combination of a virtual reality technology and a Dijkstra path planning algorithm, algorithm path nodes are distributed according to escape paths and paths through which staff of the nuclear island plant go into or out of rooms, path node attributes are set according to radiation subarea dosage rate and control information like internal locks, shield gates and so on in the nuclear plant, so that the nuclear plant three-dimensional digital map is created.

Description

technical field [0001] In the field of nuclear power, use virtual reality technology and path planning algorithms to realize item positioning and emergency escape path planning, and combine radiation partition dose rates to evaluate and three-dimensionally simulate the planned path. Background technique [0002] Under the normal operation and accident conditions of the nuclear power plant, it is particularly important to reasonably plan the personnel passage scheme inside the nuclear power plant and find out the optimal passage route to meet the requirements of the radiological protection principles, especially the ALARA principle, and ensure the safety of operating personnel. At present, the expected dose rate in the nuclear power plant is considered in the design of nuclear power plants, the radiation zones are divided, and the paths of personnel entering and exiting each room and the paths of emergency escape personnel are initially designed in combination with the plant f...

AI Technical Summary

Problems solved by technology

As a huge system, the nuclear power plant has a complex internal structure, a large number of equipment, pipes, valves, air ducts, bridges, etc., distributed in hundreds of rooms, and there are a lot of small spaces inside the plant, causing traffic obstacles, so the path The optimality and accessibility of the design need to be verified

In addition, in addition to the calculation of the dose rate in the radiation area, the radiation dose assessment work in the nuclear island plant also needs to estimate the stay time of the staff, which is a difficult point in the dose assessment work
