Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing path planning method for nuclear workers only considers the walking path of the workers, but does not consider the exposure dose of the workers, which increases the exposure dose of the workers, and there are safety problems for the workers and the environment

Abstract

The invention discloses a nuclear-related worker path planning method and system based on a BIM technology, and the method comprises the steps: S1, obtaining related parameter data of a nuclear-related plant from a BIM scene model, and carrying out the preprocessing; S2, according to the preprocessed data, the combination relation of nuclear-related plant floors is determined; S3, selecting an operator path planning starting point and an end point according to a combination relation of nuclear-related plant floors; judging whether the starting point and the ending point of the operator are on the same floor, and if so, selecting an operator path planning mode; if not, selecting the combination of the adjacent floors, and then selecting an operator path planning mode; and S4, performing operator path planning by adopting an A* algorithm to obtain a path planning result. According to the method, the walking path of the operating personnel and the exposure dose of the operating personnel are used as evaluation basis, the three-dimensional path of nuclear facility maintenance / retired personnel is planned and optimized, the exposure dose of the personnel is reduced, and the safety of the personnel and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of path planning, in particular to a method and system for path planning of nuclear operators based on BIM technology. Background technique [0002] In the maintenance / decommissioning of nuclear facilities and other nuclear-related operations, since the equipment, instruments, and pipelines are polluted by neutron activation or radionuclides during the operation of nuclear facilities, the construction environment of nuclear facility maintenance / decommissioning has strong radioactivity, and The system includes a reactor, a primary circuit, and a large number of corresponding auxiliary systems. The space is narrow, and the equipment, instruments, and pipelines are various and closely arranged. The safety risks of construction operations are high and the unpredictability is strong. It has been proved to be a safe, efficient and low-cost research method by using simulation technology to plan the walking path of ...
