Description

technical field [0001] The invention relates to the field of LNG, in particular to an unattended LNG filling station control system and method. Background technique [0002] LNG is the abbreviation of Liquefied Natural Gas in English. After natural gas is purified (removing impurities such as CO2, sulfide, hydrocarbons, and water), it is cryogenically cooled to -162°C under normal pressure and changes from a gaseous state to a liquid state. It is called liquefied natural gas, and the volume of liquefied natural gas is the same The volume of gaseous natural gas is 1 / 625, and the weight is about 45% of the same volume of water. [0003] As a clean energy source, LNG is widely used in various fields. When it involves automobiles, ships and other fields, it needs to be refueled. At present, there are a large number of LNG refueling stations in the country for refueling vehicles powered by LNG, but basically all of them require staff to refuel vehicles in the stations, which ca...
