Method and system for evaluating anti-radiation performance of lithium battery power supply module of unmanned aerial vehicle

Abstract

The invention discloses a method and a system for evaluating the anti-radiation performance of a lithium battery power supply module of an an unmanned aerial vehicle. The method comprises the following steps: simulating a nuclear radiation environment, arranging a tested lithium battery power supply module and a contrast lithium battery power supply module in and out of a nuclear radiation shielding room, obtaining the nuclear radiation dose rate R of the position where the tested lithium battery power supply module is located, turning off the voltage monitor obtains real-time output voltage and current of the two groups of lithium battery power supply modules, the nuclear radiation source until the working state of the detected lithium battery power supply module is abnormal, obtaining the number N of passed T, and calculating the maximum anti-nuclear radiation dose Rmax = N * T * R of the detected lithium battery power supply module. The system comprises a master control server, a nuclear radiation shielding room, a voltage monitor, a high-power load, a radiation source, a contrast and a tested lithium battery power supply module. The maximum anti-nuclear radiation dose is evaluated before actual detection, operation control during actual detection is facilitated, and data loss caused by falling of the unmanned aerial vehicle is avoided.

Description

technical field [0001] The invention relates to the technical field of radiation safety monitoring, in particular to a radiation resistance performance evaluation system and method based on a lithium battery power supply module of an unmanned aerial vehicle. Background technique [0002] The nuclear radiation crisis caused by the nuclear leakage accident is very serious, which has aroused the public's attention to the safety protection of nuclear facilities. Manual detection of nuclear accident sites will cause huge physical and psychological damage to operators and even endanger their lives, and it is also difficult to obtain comprehensive information on nuclear accident sites. With the development of UAV technology, the use of UAVs to enter accident areas such as nuclear leaks to detect and obtain information has become a current research hotspot. In the process of drones detecting nuclear radiation areas, lithium batteries are usually used to power drones, which can prov...

Problems solved by technology

[0003] However, when the lithium battery power supply module itself is subjected to nuclear radiation, the anti-nuclear radiation performance of its circuit system is limited.

At the same time, in the prior art, the maximum nuclear radiation dose that the lithium battery power supply module can withstand is not uniformly calibrated, and the maximum nuclear radiation dose that each lithium battery power supply module can withstand is also different. It is not easy to detect abnormalities and damages caused by radiation. Once the lithium battery power supply module fails during the drone detection process, the drone will fall in the nuclear radiation area, lose the detection data, and increase the detection cost.
