Background
The increasing environmental problems and energy crisis have led to a constant search for alternative fuels for automotive engines. LNG (Liquefied natural gas) is a clean and efficient energy source and can be used as fuel for automobile engines. LNG is filled into a gas storage bottle of an automobile through a gas filling gun of an LNG filling machine, and the LNG is liquid formed by condensation of natural gas in a gaseous state at normal pressure after being cooled to-162 ℃, so that the LNG reserved in the gas filling gun is prevented from bursting of a pipeline due to external relatively high temperature and relatively low pressure gasification, and therefore when the gas filling gun is in an idle state (namely, liquid is not added), a gas return valve of the gas filling gun needs to be ensured to be in an open state. The LNG refueling station uses a one-pump-one-gun mode initially, but as the number of users of LNG vehicles increases, the queuing phenomenon becomes more and more serious, and in order to solve the problem of serious queuing, a one-pump-two-gun or one-pump-multiple-gun mode has been proposed, but this mode needs to realize the interlocking linkage work between the above "two guns" or "multiple guns", that is, when only one refueling gun is working, the air return valves of all refueling guns should be ensured to be in a closed state, and when all refueling guns are in an idle state, all air return valves should be ensured to be in an open state. In order to realize the interlocking linkage, all the air guns can be ensured to be mutually informed of whether all the other air guns are in a liquid adding state or an idle state, and then the air return valves of the air guns are correspondingly controlled to be opened or closed.
In prior art, in order to realize that each air gun can learn the state of other air guns, adopt and set up the cable between every two air guns to realize the communication through two kinds of levels of height (two kinds of levels of height correspond respectively air gun's idle state and liquid feeding state), in order to inform the other side in what kind of state of oneself, but this kind of scheme has a problem: when the quantity of air gun needs to be increased, two liang of communication cables need to be added between newly-increased air gun and every existing air gun, and when reducing the air gun, need demolish the air gun that is subtracted and the communication cable between two liang of other air guns, realize the degree of difficulty often very big at the scene, and when having the air gun to break down in the system, all the other air guns also can't know.
