Problems solved by technology

[0004] 1. Due to the lack of effective path planning, it is difficult to ensure the lowest possible exposure dose level and the shortest stay time during the process of stepping out, which increases the risk of personnel exposure dose
[0005] 2. Relying solely on the actual experience of the staff to carry out path checkpoints, lack of effective maintenance path optimization means

Abstract

The invention discloses a maintenance path planning method and device for a nuclear power plant. The method includes: according to the distribution of radiation zones and radiation hotspots in the nuclear power plant, making a three-dimensional digital nuclear power plant into a navigation grid required for path finding; according to a preset heuristic search algorithm, selecting a suitable maintenance path in the navigation grid , so that the maintenance personnel who pass the maintenance path receive the lowest radiation dose. In the present invention, by introducing radiation data information into the three-dimensional scene of the nuclear power plant, the dose level of maintenance exposure is used as the evaluation standard for path search, and the heuristic search method is used to automatically search for the path in the three-dimensional scene of the nuclear power plant. Under reasonable and as low as possible level conditions, it can effectively approach the maintenance target area, providing maintenance personnel with excellent maintenance path planning, and at the same time, it also greatly improves the efficiency of maintenance path planning, so that the maintenance of nuclear power plants can be carried out quickly and reliably.

Description

Technical field [0001] The present invention relates to the field of path planning, and in particular, to a nuclear power plant maintenance path planning method and apparatus. Background technique [0002] At present, the nuclear power plant is maintained, it is necessary to allow radiation protection personnel to measure the radiation level of the work area in advance, and the maintenance personnel can enter the work area for on-site environmental exploration only within the range of radiation doses. At present, the site steppoint of nuclear power maintenance can only rely on the actual experience of maintenance personnel, and cannot analyze the distribution characteristics of the radiation dose field in advance, and the irradiance of irradiation in the operation cannot be pre-evaluated, so that the maintenance path cannot be effectively planned. It is guaranteed that the subject remains as low as possible. [0003] Therefore, the selection of the existing nuclear power station ...
