When the preset pressure threshold value of pressure detection control device (11), intelligent pressure switchs SB and controls first by time-delay relay KT
Solenoid valve (9) connects, and nitrogen is treated air charging system by source of the gas gas cylinder (8) through the first solenoid valve (9) and the first check valve (10)
(12) inflate；
When the atmospheric pressure value when air charging system (12) is equal to or higher than the preset pressure threshold value of pressure detection control device (11), intelligence
Energy pressure switch SB passes through time-delay relay KT and the first solenoid valve (9) is controlled to disconnect, and stops inflation；
The boost charge-air step is specific as follows：
First, by boost charge-air unit（18）With treating that air charging system (12) connects；Secondly, pass a test feedback control unit（17）
On pressure detection control device (11) detection treat the atmospheric pressure values of air charging system (12)；When the atmospheric pressure value for treating air charging system (12) is low
When the preset pressure threshold value of pressure detection control device (11), intelligent pressure switchs SB and controls second by time-delay relay KT
Solenoid valve (15) connects, and nitrogen is treated air charging system by source of the gas gas cylinder (8) through second solenoid valve (15) and the second check valve (13)
(12) inflate；When the atmospheric pressure value for treating air charging system (12) is equal to or higher than the preset pressure threshold value of pressure detection control device (11)
When, intelligent pressure switchs SB and by time-delay relay KT second solenoid valve (15) is controlled to disconnect, and stops inflation.
5. a kind of nitrogen according to claim 4 fills compensating method, it is characterised in that：The predetermined time of the b operating modes is
2-10 seconds or 10 seconds-15 seconds predetermined time；The preset pressure threshold value of the pressure detection control device (11) for 0.4MPa-
