Abstract

The invention provides a field flaw detection operation radiation inspection method and system based on an unmanned aerial vehicle. The method provided by the invention comprises the following steps: determining a first electronic fence according to accelerator parameters, and determining a first search direction of the unmanned aerial vehicle by taking an intersection point of the boundary of the first electronic fence and the beam-out direction of the accelerator as a first starting point according to the beam-out direction of the accelerator; the unmanned aerial vehicle searches a boundary starting point of the control area according to the first search direction; determining a detour direction according to radiation distribution characteristics of the boundary of the first electronic fence; starting from the starting point of the boundary of the control area, flying around the accelerator according to the bypassing direction, and detecting the boundary of the control area; determining a supervised area boundary according to the control area boundary and the radiation dose equivalent rate obtained by detection; determining a task type; and the unmanned aerial vehicle completes inspection tasks in the control area and the supervision area according to the task type. The invention provides a field flaw detection operation radiation inspection method and system based on an unmanned aerial vehicle. The method and system are used for carrying out fine division of actual areas on a control area and a supervision area of radiation detection.
