A detection system and detection method of a gas vehicle leakage alarm device

Abstract

The invention discloses a detection system and a detection method of a gas vehicle leakage alarm device, which are suitable for various alarm performance tests. Among them, the detection system is equipped with a box body, and gas cylinders, gas detection cabins, controllers, human-computer interaction interfaces, exhaust fans, etc. are set inside and outside the box; there is an annular air passage and a gas alarm detector detection platform in the detection cabin. A gas mixing motor is installed at the bottom outside the cabin, and the gas mixing motor extends into the air inlet through a dynamic seal to connect with a gas mixing fan; the detection cabin is designed with gas inlet and outlet, and the gas is controlled by a flow controller. The device is highly integrated, safe, and gas distribution High precision, high test accuracy, good sealing, good test interchangeability, applicable to various alarm performance tests, including alarm action value test, response time test, power-on alarm test, alarm durability test, airflow resistance test, High concentration submersion test.

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...
