Description

technical field

[0001] The invention relates to the field of automobiles, in particular to a gas leakage alarm system for LNG heavy trucks. Background technique

[0002] In recent years, liquefied natural gas (LNG) and compressed natural gas have been widely used as clean energy in industry and commerce, urban residents and the automobile industry. The gas leakage alarm system is an important system to ensure production and personal safety. It has been widely used in oil refineries, oil depots, liquefied gas stations, gas stations, gas stations, painting rooms, home production rooms and other places that emit flammable gases and vapors. In order to detect the content of combustible gas in time, find the leakage as soon as possible, and eliminate the danger. The principle of the gas leakage alarm system is that when the concentration of combustible gas reaches the set alarm value, the combustible gas alarm will send out an alarm signal to remind to take safety measures as so...
