Problems solved by technology

[0005] However, the existing technology cannot deal with the estimation of real-time dose and cumulative dose in complex radiation environments, and it is inconvenient for operators to check their own exposure doses in real time during the operation process, and it is not convenient for operators to intuitively judge whether the current radiation environment is within their Within the range that the body can accept, it is easy to cause psychological depression, panic and other mental states that are not conducive to work safety

Embodiment 1

[0057] According to a preferred embodiment, before path planning, it is necessary to obtain the coordinate data of the currently operated equipment and the operator in the real scene, so that the dosimeter system 10 can call the 3D corresponding to the current scene according to the coordinate data. The scene model and the corresponding visualized radiation field, therefore, preferably, the path planning method in the visualized radiation field includes a positioning method, preferably, the positioning method includes the following steps:

[0058] S11: The positioning module 11 scans the location information of the current device. Preferably, the information can be stored in a two-dimensional code to obtain the location information of objects in the current environment and parse it into three-dimensional coordinate data. Preferably, the element used for scanning in the positioning module 11 may be a laser scanning device, or an optical image capturing device (camera).

Embodiment 2

[0065] This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated here.

[0066] According to a preferred embodiment, the dosimeter system 10 can perform visualization operations on the invisible radiation field so that the user can directly observe the distribution state of the radiation field on the display module 14 and can perform operations such as rotating and cutting the visualized radiation field In order to observe the dose intensity of the radiation field from different angles and different depths, a preliminary artificial assessment of the safety factor of the working environment can be carried out before starting the operation, and an effective judgment basis can be provided for planning a reasonable operation path.

[0067] According to a preferred embodiment, the radiation distribution data in the radiation environment is pre-stored in the dosimeter system 10, so that the dosimeter system 10 can directly call the existing r...

Embodiment 3

[0078] This embodiment is a supplementary description of Embodiment 2, and repeated content will not be repeated.

[0079] According to a preferred embodiment, the user can plan the path of the operation scene through the portable dosimeter 1, so as to obtain the optimal working path during the operation and reduce the effective dose of radiation received by the human body. The planning of the optimal working path can be realized by the dosimeter system 10. Preferably, after the three-dimensional scene model and the corresponding visualized radiation field are loaded, the dosimeter system 10 can specify the starting point, end point, passing point, and The user's scheduled working time calculates the effective dose received by the user during the operation, and simulates at least one operation path for the user to choose. Among them, the path with the smallest accumulated value of the total effective dose received by the user is called the optimal operation path. . Preferably...

Description

technical field [0001] The invention relates to the technical field of radiation protection, in particular to a real-time path planning method and device based on a visualized radiation scene. Background technique [0002] At present, the world's energy demand is increasing day by day, including my country, which is vigorously promoting clean energy. Among them, nuclear energy, as a high-efficiency and pollution-free energy supply method, is being adopted by more and more countries. my country's nuclear power has become a Zhang's national business card and the construction of domestic nuclear power plants are just in the ascendant. [0003] Nuclear power plants and related nuclear facilities contain radioactivity, which poses potential dangers to humans and the environment. When operating in a radioactive environment, including the maintenance of equipment and facilities, and the dismantling process in the decommissioning of nuclear facilities, the first thing to consider is ...
