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

Abstract

The invention discloses a radiation resistance performance evaluation method and system of a lithium battery power supply module of an unmanned aerial vehicle. The method includes: simulating a nuclear radiation environment, setting a tested lithium battery power supply module and a control lithium battery power supply module inside and outside a nuclear radiation shielding room, Obtain the nuclear radiation dose rate R where the lithium battery power supply module under test is located, and the voltage monitor obtains the real-time output voltage and current of two sets of lithium battery power supply modules, and turn off the nuclear radiation source until the working state of the lithium battery power supply module under test is abnormal , to get the number N of the passed T, and calculate the maximum anti-nuclear radiation dose R of the tested lithium battery power supply module max =N×T×R. The system includes a master control server, a nuclear radiation shielding room, a voltage monitor, a high-power load, a radiation source, a control and a tested lithium battery power supply module. The invention evaluates the maximum anti-nuclear radiation dose before the actual detection, facilitates the operation and control during the actual detection, and avoids data loss caused by the fall of the drone.

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.
