Specifically, when humidity sensor 206 detects that the humidity of the air in the oven is 33.0g/kg (greater than the humidity value standard of 25 g/kg), which indicates that the humidity of the air in the oven is increased, the air discharge amount needs to be increased to 70000m for carrying out the year/h, the static pressure value detected by static pressure sensor 205 is smaller than the static pressure standard value parameter of-10 Pa, and the air supply amount needs to be automatically increased to 63000 m for carrying out the year/h; when the humidity sensor 206 detects that the humidity of the air in the oven is 26g/kg (for example, the humidity value is 25g/kg, the humidity value is plus or minus 2 from the humidity value standard and is regarded as being substantially equal to the humidity value standard), it indicates that the humidity of the air in the oven can meet the process requirements, at this time, the air discharge amount does not need to be increased, and only the current air discharge amount needs to be maintained, and at this time, the static pressure value detected by the static pressure sensor 205 is also equal to or substantially equal to the static pressure standard value parameter (the static pressure standard value is-10 Pa, and the static pressure value is plus or minus 5Pa from the static pressure standard value and is regarded as being substantially equal to the static pressure standard value), so that the current air volume operation is maintained; when the air humidity in the humidity sensor 206 oven is 21g/kg (less than 25g/kg of humidity value standard), it is described that the air in the oven is very dry, and the drying requirement can be completely met, and at the moment, the process level can be met only by keeping the air exhaust air quantity as small as possible, so that the energy consumption of the system is reduced, namely: and if detecting that the exhaust air volume is smaller than the minimum exhaust air volume value of 45000 m/h, maintaining the current air volume operation, and correspondingly, reducing the air supply volume to 43000m for cultivation/h when the detected static pressure value is larger than the static pressure standard value parameter.
