The application provides a motion control method and a motion control system for a detecting device for a radioactive solid waste bucket. The method comprises the following steps: dividing the radioactive solid waste bucket into a plurality of voxels and dividing the radioactive solid waste bucket into a plurality of detection levels along an axial direction; selecting an initial detection level, and determining an intersection point which passes a circle center of the initial detection level and is vertically intersected with a vertical surface as an initial detection position; calculating initial detection positions of a radioactive source and a detector according to the initial detection position; calculating a motion curve of the radioactive solid waste bucket according to the initial detection position and the mass of the radioactive solid waste bucket; calculating motion curves of the radioactive source and the detector according to the motion curve of the radioactive solid waste bucket and the initial detection positions of the radioactive source and the detector; controlling a waste bucket horizontal motion mechanism, a radioactive source vertical motion mechanism, a detector vertical motion mechanism and a detector horizontal motion mechanism to synchronously operate according to all the motion curves; detecting radionuclide in the radioactive solid waste bucket. According to the technical scheme provided by application, the coordination and the detection efficiency of all mechanisms in the detecting device can be improved.
Description
technical field [0001] The present application relates to the technical field of radioactive material detection, and more specifically, to a motion control method and system for a radioactive solid waste barrel detection device. Background technique [0002] With the continuous development of new energy technologies, nuclear energy, as a high-efficiency new energy, is widely used in power generation and other fields. However, in the process of nuclear power generation, it is easy to generate a large amount of low- and medium-level radioactive waste. These low- and medium-level radioactive wastes are required to be packed in drums, and stored and transported according to the type and activity of radionuclides. Because the low- and medium-level radioactive waste in the barrel is radioactive, non-destructive testing technology has become the main detection method for the type and activity of the nuclide in the barrel. [0003] The non-destructive testing devices for radioactiv...
