With the development of information technology, various unmanned equipment has made significant progress, and unmanned equipment for nuclear radiation detection has also been put into use. The high-altitude detection and inspection unmanned aerial vehicle system, combined with technologies such as the Internet of Things, drones, and nuclear monitoring, provides an integrated nuclear radiation monitoring solution for the fields of nuclear power, environmental protection, and safety, achieving multi-dimensional and accurate radiation monitoring in the air. Compared with traditional monitoring methods, the use of high-altitude reconnaissance and inspection unmanned aerial vehicle monitoring systems has rapidly improved the detection ability of daily monitoring. By deploying unmanned aerial vehicles at various stages of nuclear accidents, it can quickly deploy and grasp the environmental radiation level and the accumulation and expansion of radioactive substances in real time. This can reduce the radiation dose of frontline workers and effectively protect their safety. The main configuration includes: V-energy spectrum measurement unit, aerosol sampling device (optional), video monitoring equipment, GPS/Beidou positioning equipment, wireless communication equipment, power supply equipment remote control terminal, unmanned aerial vehicle flight platform, and high maneuverability dispatch platform.
