Method and system for evaluating the anti-nuclear radiation performance of UAV video acquisition module

Abstract

The invention discloses a method and a system for evaluating the anti-nuclear radiation performance of a video acquisition module of an unmanned aerial vehicle. The method includes: simulating a nuclear radiation environment, arranging a video acquisition module in a nuclear radiation shielding room, and acquiring the nuclear radiation where the video acquisition module under test is located. Dose rate R, every time interval T, the video acquisition module transmits the collected data information to the master control server until the working state of the video acquisition module is abnormal and the nuclear radiation source is turned off, the number N of T passing through is obtained, and the video is calculated. The maximum anti-nuclear radiation dose R of the acquisition module max =N×T×R. The system includes a master control server, a nuclear radiation shielding room, a regulated power supply, a nuclear radiation source, a background picture, a video acquisition module and a fill light. The present invention evaluates and calibrates R before actual detection max , which is convenient for operation and control during actual detection, and avoids data loss caused by abnormal operation or damage of the video acquisition module.

Description

technical field [0001] The invention relates to the technical field of radiation safety monitoring, in particular to a system and method for evaluating the anti-nuclear radiation performance of a video acquisition module based on an unmanned aerial vehicle. Background technique [0002] There have been accidents in history that resulted in the leakage of a large number of radioactive materials, and the radiation hazards are serious. In 2011, the nuclear leakage accident at the Fukushima Daiichi nuclear power plant in Japan due to the impact of the earthquake caused a very serious nuclear radiation crisis. The nuclear radiation crisis caused by the nuclear leakage accident has aroused public attention to the safety protection of nuclear facilities. Manual detection of the location of the nuclear accident will cause huge physical and mental damage to the operators and even endanger their lives, and it is difficult to obtain comprehensive information on the location of the nuc...

Problems solved by technology

[0003] However, the anti-nuclear radiation performance of the circuit system of the video acquisition module itself is limited when it is subjected to nuclear radiation.

At the same time, in the prior art, the maximum nuclear radiation dose that the video acquisition module can withstand is not uniformly calibrated, and the maximum nuclear radiation dose that each video acquisition module can withstand is also different. In the actual detection process, the circuit is damaged due to excessive nuclear radiation. When abnormality and damage occur, it is not easy to be detected manually, and the image quality of the video image acquisition is low, and even the detection data is lost due to the damage of the video acquisition module, which increases the detection cost
