With the above example, when the indoor humidity is less than the lower limit of the preset humidity range by 10%, comparing the indoor humidity with the outdoor humidity, when the indoor humidity is greater than the outdoor humidity, generating a second closing control instruction, sending the second control instruction to the ventilation device of the greenhouse, controlling the ventilation device to close the fan, and closing all the front ventilation and the upper ventilation.
It can be understood that when the indoor humidity is within the preset humidity range, the humidity parameter meets the preset condition, and the state of the current roller shutter equipment and the ventilation equipment is maintained without regulation and control, and a control instruction is not generated. When the indoor humidity is not within the preset humidity range, a control instruction is generated to regulate and control the humidity parameters, so that the humidity parameters of the greenhouse can be regulated and controlled automatically, and management personnel are not required to regulate and control locally or remotely manually.

When the illumination parameter does not meet the preset condition, the specific condition of the illumination parameter needs to be judged to generate a control instruction when the illumination parameter is taken as the target environment parameter, and the illumination parameter is regulated and controlled to enable the illumination parameter of the greenhouse to gradually meet the preset condition. The preset condition of illumination can be a preset illumination range or a preset illumination threshold, and when the preset illumination threshold is the preset illumination threshold, the preset illumination threshold is used as the upper limit of the preset illumination range and the lower limit of the preset illumination range. For example: the preset illuminance ranges from 10000lx to 50000lx.
Specifically, the illumination parameters include indoor illuminance and outdoor illuminance, and when the indoor illuminance is greater than the upper limit of the preset illuminance range, the indoor illuminance and the outdoor illuminance are judged.
