The minimum wind speed of the auxiliary air curtain machine is calculated by the following formula: V1/V2 min＝(H-h2)/h2min; wherein V1 is a preset wind speed of the main air curtain machine, V2 min is a minimum wind speed of the auxiliary air curtain machine, H is the height of a door opening where the air curtain machine equipment is located, and H2 min is a minimum value of the preset height range;
Controlling the wind speed of the auxiliary air curtain machine to operate between the maximum wind speed value and the minimum wind speed value.
6. The method of claim 4, wherein after identifying that the person is near the door opening and is a preset distance away, the method further comprises:
The height of the human body is identified, and a preset height range is determined according to the height.
7. The method according to claim 4, wherein the method further comprises:
When detecting that a person passes through the area where the auxiliary air curtain machine is located, controlling the auxiliary air curtain machine to be started;
When detecting that no person passes through the area where the auxiliary air curtain machine is located within a preset time, controlling the auxiliary air curtain machine to be closed; when the air curtain machine equipment comprises a plurality of auxiliary air curtain machines, the auxiliary air curtain machines are uniformly arranged in the area below the door opening.
8. A control device for an air curtain apparatus, the device comprising:
The monitoring module is used for monitoring the preset wind speed of the main air curtain machine;
the identifying module is used for identifying whether the human body approaches to the door opening;
The regulation and control module is used for regulating and controlling the wind speed of the auxiliary air curtain machine according to the preset wind speed and the preset height range of the main air curtain machine after the identification module identifies that the human body is close to the door opening and is away from the door opening, so as to ensure that the lateral air flow generated by the main air curtain machine and the auxiliary air curtain machine relative to the air outlet is kept in the preset height range;
The regulation and control module is specifically used for calculating the wind speed of the auxiliary air curtain machine through the following formula: v1/v2= (H-H2)/H2; wherein V1 is the preset wind speed of the main air curtain machine, V2 is the wind speed of the auxiliary air curtain machine, H is the height of a door opening where the air curtain machine equipment is located, and H2 is a preset value in the preset height range; and then controlling the operation of the auxiliary air curtain machine according to the calculated wind speed of the auxiliary air curtain machine.
9. A computer readable storage medium, on which a computer program is stored, characterized in that the program, when being executed by a processor, implements the method according to any of claims 4 to 7.
10. An electronic device, comprising:
one or more processors;
Storage means for storing one or more programs which when executed by the one or more processors cause the one or more processors to implement the method of any of claims 4 to 7.
