Description
technical field [0001] The invention relates to gas vehicle leakage alarm detection technology, in particular to a detection system and detection method of a gas vehicle leakage alarm device. Background technique [0002] Because gas vehicles have the advantages of low cost of use and low environmental pollution, most operating vehicles choose gas vehicles, which also makes my country's number of gas vehicles rank first in the world for a long time. However, the gas vehicle market in my country has been in a relatively chaotic state. Most gas vehicles are refitted from fuel vehicles. The construction specifications are difficult to guarantee, and follow-up supervision is not strict. As a result, gas vehicles are full of hidden dangers like walking bombs, and accidents occur frequently. It poses a threat to the life and property safety of the broad masses of the people. [0003] Accidents of gas vehicles are mainly caused by gas leakage. Therefore, in the standards GB 7258-20...
