Different operating modes can be used using object and demand for different in four root phases, and different working modes can be by
This four root phases are composed according to certain rule.
Wherein, by taking embodiment illustrated in fig. 1 as an example, the air pressure decline control mode of air pressure decline stage is as follows in cabin:
The stage, frequency converter 31 controls vacuum pump 3 and opens, to being evacuated out of my cabin, while only by the first air inlet pipe 21 to cabin
Interior air inlet, i.e. solenoid valve 221, solenoid valve 231 and solenoid valve 251 are in closed state.It will be appreciated by those skilled in the art that
First air inlet pipe, 21 air inflow answer it is relatively small, to realize the decline of air pressure.During dropping under pneumatic pressure, pass through pressure sensing
Device 5 detects pressure change in cabin, when detecting that rate of pressure change is more than setting value, adjusts frequency converter by master board 4
31, the output power of vacuum pump 3 is reduced, reduces sucking rate until rate of pressure change meets sets requirement in cabin, and works as detection
When being lower than setting value to rate of pressure change, frequency converter 31 is adjusted by master board 4, improves the output power of vacuum pump 3, is increased
Add sucking rate until rate of pressure change meets sets requirement in cabin.Herein, setting value can be a point value, also may include

The control of 22 air inflow of pipe carries out the adjusting of rate of pressure change.In this case it can cancel frequency converter 31.For example, being evacuated
In the process, pressure change in the cabin that master board 4 is detected according to pressure sensor 5 controls and is arranged in the second air inlet pipe 22
Ratio valve regulation air inflow, when the air inflow of the ratio valve regulation reaches the upper limit and rate of pressure change is still higher than setting value,
Then further opens solenoid valve 251.
By taking embodiment illustrated in fig. 1 as an example, the air pressure of air pressure plateau maintains control mode as follows in cabin:
Vacuum pump 3 is first controlled by frequency converter 31 and keeps stable output power, stablizes sucking rate, is then turned on solenoid valve
221, solenoid valve 231 and solenoid valve 251 are in close state.Pressure sensor 5 detects air pressure change in cabin, if air pressure is opened in cabin
Begin to rise the output power for then increasing vacuum pump 3 by control frequency converter 31 by master board 4, until stable gas pressure is being set in cabin
In definite value；Conversely, reducing the output of vacuum pump 3 by control frequency converter 31 by master board 4 if air pressure in cabin is begun to decline
Power, until stable gas pressure is in setting value in cabin.When the output power of the vacuum pump 3 controlled by frequency converter 31 reaches lower limit
And air pressure is when being still below setting value, then opens solenoid valve 251 carries out auxiliary pumping and adjusts.Herein, setting value can be a point
Value, also may include upper limit value and lower limit value.
By taking embodiment illustrated in fig. 1 as an example, it is as follows to rise control mode for the air pressure of air pressure ascent stage in cabin:
Method 1: the control method of vacuum pump 3 is not closed.Solenoid valve 221 is in the open state, solenoid valve 231 and solenoid valve
251 are in close state, and the output power of vacuum pump 3 is reduced by frequency converter 31, reduce sucking rate, pass through pressure sensor 5
Air pressure in cabin is detected, when to reach lower limit air pressure climbing speed still low for the output power of the vacuum pump 3 controlled by frequency converter 31
When setting value, opens solenoid valve 251, while 3 output power of vacuum pump is adjusted by frequency converter 31, until air pressure rises in cabin
Rate reaches setting value.
Method 2: the control method of vacuum pump 3 is closed.The operating for stopping vacuum pump 3, at solenoid valve 231 and solenoid valve 251
In closed state.Opens solenoid valve 221, pressure sensor 5 detect air pressure in cabin, if air pressure climbing speed is greater than setting in cabin
Value, then close solenoid valve 221；If air pressure climbing speed is less than setting value in cabin, further opens solenoid valve 251, utilization is auxiliary
Exhaust tube 25 is helped to carry out tonifying Qi.Herein, setting value can be a point value, also may include upper limit value and lower limit value.
