(4) if, the pressure data after smothing filtering limit below P2 in press belt, connect the small supercharging of ground distribution platform
Valve；
For vent valve：
(5) if, pressure data after smothing filtering be pressurized more than limit more than Pbz in press belt for the first time, connect and deflate
Valve, now show occur being pressurized more than failure；Following strategy is performed afterwards：If the pressure data after smothing filtering is in pressure
Below P2 is limited in band, then disconnects vent valve；If the pressure data after smothing filtering is connected more than press belt upper limit P3
