Water body gamma radiation stereoscopic monitoring system and method based on autonomous underwater vehicle

Abstract

The invention discloses a water body gamma radiation stereoscopic monitoring system and method based on an autonomous underwater vehicle. Modular design is adopted, and the water body gamma radiationstereoscopic monitoring system comprises a gamma radiation detection module, a control module, an energy module and a power module; the gamma radiation detection module extracts gamma radiation in real time, quickly judges whether artificial radioactive nuclides exist or not through a deep learning network system, and collects detection data; the control module adopts an intelligent path planningsystem with Gaussian process regression to control the autonomous underwater vehicle to conduct intelligent cruising according to the gamma radiation measurement result. By means of the water body gamma radiation stereoscopic monitoring system, it can be achieved that stereoscopic distribution of the activity concentration of gamma radiation nuclides in the water body can be efficiently and precisely measured.

Description

technical field [0001] The invention belongs to the field of radioactive monitoring of water bodies, and in particular relates to a three-dimensional monitoring system and method for gamma radiation of water bodies based on underwater autonomous vehicles. Background technique [0002] With the gradual advancement of my country's new energy strategy, nuclear energy has gradually become an important part of my country's energy structure due to its advantages of high efficiency, environmental protection, strong continuous energy supply, and high technological maturity, and nuclear power safety has become the focus of public attention. At present, the number of coastal nuclear power plants has increased significantly. In the next two decades, there will be 300 coastal nuclear power plants in China, Japan and South Korea alone in Asia. If an accident occurs in a nuclear power plant, it may cause the release of radioactive substances to the environment, causing the radioactive sub...

Problems solved by technology

In nuclear accident emergency, the three-dimensional distribution measurement of artificial radionuclide activity concentration in polluted sea area is the premise of formulating emergency plan, but the area of ​​radionuclide pollution in water body is large and has high uncertainty, and the efficiency of large-scale sampling measurement is very low. Low, unable to meet the needs of rapid nuclear emergency response
