6. The method for checking an abnormality of an inflator garage according to claim 3, wherein the main inflation line health condition checking method specifically executes a strategy (step) as follows:
(1) starting conditions were as follows: after the health condition of the electric control exhaust valve is checked, the influence of environmental factors is low, all the controllable valve groups are closed, the electric control exhaust valve is closed, and the check is started when the pressure of the hangar is stable and no abnormality exists;
(2) and (3) opening a controllable valve group of a gas column, recording the pressure value of the gas collection cabin after the pressure is stable, recording the pressure value of the gas collection cabin again after a certain time, subtracting the gas leakage amount of the controllable valve group of the gas column from the result, subtracting the gas leakage amount of the gas column, wherein the obtained result is the gas leakage amount of the gas collection cabin, and when the gas leakage amount exceeds a certain value, judging that the gas leakage of the gas collection cabin is serious.
7. The method for inspecting an abnormality of an inflator-store according to claim 3, wherein the gas column maintenance in the method for inspecting a health condition of a gas column of an inflator-store is: the hangar adopts many gas columns structure, when single or many different positions gas column broke down, can use controllable valves completely to amputate trouble gas column and carry out gas column maintenance operation, main gas-filled pipeline overhauls: when main gas charging line trouble need be overhauld, need to rise each gas column pressure of hangar behind the stable value, close whole controllable valves, disconnection electrical system actuating mechanism power can overhaul main gas charging line operation, overhauls the back, again with the system resume normal condition can: valve maintenance: when the electric control exhaust valve is overhauled, after the pressure of each air column of the hangar rises to a stable value, the power supply of the fan and the electric control exhaust valve is disconnected, all controllable valve groups are closed, the overhauling operation of the electric control exhaust valve can be carried out, when the controllable valve groups are overhauled, after the pressure of each air column of the hangar rises to a stable value, all the controllable valve groups without faults are closed, the faulty controllable valve groups are pulled out, and the sealing covers are used for buckling the connecting ports on the air columns.
