Description

Technical field

[0001] The invention relates to the technical field of liquefied gas refueling station systems, in particular to an integral liquefied gas refueling station system and an operation method thereof; it can be managed through remote monitoring, which is beneficial to accelerate the use of liquefied clean gas in urban vehicles, and can effectively improve The air quality of the city. Background technique

[0002] With the process of urbanization in my country, the number of various automobiles has increased sharply. How to reduce the impact of automobile exhaust emissions on the surrounding air quality has also attracted more and more attention. At present, many cities have adopted the promotion of the use of some clean energy sources, such as liquefaction. Petroleum gas, high-pressure natural gas, etc., these clean energy sources have indeed played a certain role in promoting urban environmental protection.

[0003] However, the effect of the current promotion is not...
