When only one person passes through the door opening, the embodiment provides a preferred embodiment, namely the controller is specifically configured to calculate the wind speed of the auxiliary air curtain machine according to the following formula: v1/v21=s1/(S-S1); v1/v22=s2/(S-S2); wherein V1 is the preset wind speed of the main air curtain machine, V21 is the first wind speed of the auxiliary air curtain machine, V22 is the second wind speed of the auxiliary air curtain machine, S is the width of the door opening, and S1 is the distance between the human body and one side of the door opening; s2 is the distance between the human body and the other side of the door opening; thereafter, the wind speed of the auxiliary air curtain machine is controlled to operate between the first wind speed and the second wind speed.
When a plurality of people pass through the door opening, the embodiment provides a preferred embodiment, namely the controller, for controlling the wind speed of the auxiliary air curtain machine to achieve a better dust removal effect, and the wind speed of the auxiliary air curtain machine is calculated by the following formula: v1/v21=s11/(S-S11); v1/v22=s22/(S-S22); wherein V1 is the preset wind speed of the main air curtain machine, V21 is the first wind speed of the auxiliary air curtain machine, V22 is the second wind speed of the auxiliary air curtain machine, S is the width of the door opening, and S11 is the distance between the nearest human body position on one side of the door opening and one side of the door opening; s22 is the distance between the nearest human body position on the other side of the door opening and the other side of the door opening; thereafter, the wind speed of the auxiliary air curtain machine is controlled to operate between the first wind speed and the second wind speed.
In general, the main air curtain machine is in a normally open state and is mainly used for blocking mosquitoes, dust, heat insulation and the like in the air. The auxiliary air curtain machine is in a normally closed state. In the case where the air curtain apparatus includes a plurality of auxiliary air curtain machines, the door opening area may be divided into a plurality of areas, one for each of the auxiliary air curtain machines. On the basis, the air curtain machine equipment further comprises: the detection module is correspondingly arranged with each auxiliary air curtain machine and is used for controlling the auxiliary air curtain machines to be started when detecting that the area where the auxiliary air curtain machines are located passes by; and the auxiliary air curtain machine is also used for controlling the auxiliary air curtain machine to be closed when no person passes through the area where the auxiliary air curtain machine is located within the preset time.
Example 2
FIG. 3 is a flow chart of a method of controlling an air curtain apparatus according to an embodiment of the invention, as shown in FIG. 3, the method comprising the steps of:
Step S301, monitoring a preset wind speed of a main air curtain machine;
step S302, after recognizing that the human body is close to the door opening and is away from the door opening by a preset distance, the wind speed of the auxiliary air curtain machine is regulated and controlled according to the preset wind speed of the main air curtain machine and the distance between the human body and the two sides of 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 within a preset width range.
It should be noted that the preset width range is a lateral width range of the lateral airflow moving laterally at a constant speed (or non-constant speed) at the door opening. The control logic of the air curtain machine provided by the embodiment controls the wind speed of the auxiliary air curtain machine, so that the main air curtain machine and the auxiliary air curtain machine blow in opposite directions to form lateral air flow, the lateral air flow is kept in the preset width range of the door opening, and the preset width range can be centered on the center point of the door opening. Can effectively blow off dust, mosquito and the like on the human body, so that the dust and the mosquito carried by the human body are left outdoors, the air is prevented from entering indoors, and the indoor air quality and the environmental sanitation are improved.
The auxiliary air curtain machines can be divided into a plurality of areas, namely the door opening is divided into a plurality of areas, each area is provided with an auxiliary air curtain machine which can be independently started and stopped for control, each auxiliary air curtain machine is tightly connected, and whether air gaps exist at the connection positions of two adjacent auxiliary air curtain machines when the two adjacent auxiliary air curtain machines run simultaneously is avoided. For example, the door opening is divided into A, B, C, D areas, and each area is provided with an auxiliary air curtain machine which can be controlled independently.
The regional division of the door opening can be divided according to actual conditions. For example, when the door opening is wide, a plurality of areas are divided, and if the door opening is narrow, a plurality of areas are divided, but the width of each area is set to be more than 0.6 meter. The body width H of most normal people is about 0.4 meter, but the lateral airflow width is wider than the body width, and the effect of blowing off dust of the human body by the lateral airflow is better.
When the induction device detects that a person enters the room from a certain area of the door opening, the auxiliary air curtain machine in the area is controlled to start to operate, and the auxiliary air curtain machines in other areas are not started. For example, when a person enters the room from the area A, and when the sensing device senses that the person enters the room in the area A, the air curtain machine in the area A is controlled to be started, and the starting and stopping control mode is controlled according to the control mode.
When a plurality of persons enter the room from a plurality of areas at the same time, the auxiliary air curtain machines of the corresponding plurality of areas are controlled to start and run at the same time. In addition, if people enter the room from the boundary of the two areas, the auxiliary air curtain machines in the two adjacent areas are simultaneously controlled to start and run, so that only half of the body of the people is prevented from being blown by the lateral air flow, and the effect of blowing off dust of the human body can not be achieved.
In general, the main air curtain machine is in a normally open state and is mainly used for blocking mosquitoes, dust, heat insulation and the like in the air. The auxiliary air curtain machine is in a normally closed state. 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 the preset time, controlling the auxiliary air curtain machine to be closed; wherein, when air curtain machine equipment includes many auxiliary air curtain machines, auxiliary air curtain machine evenly sets up the region below the door opening.
For example, when a person walks from the outside to the position 0.5m in front of the door opening, the sensing device senses that the person is at the position 0.5m away from the door opening, and transmits information to the controller, and the auxiliary air curtain machine is started, and the specific control mode of the auxiliary air curtain machine is as follows:
The auxiliary air curtain machine height is set to 0.5m, namely the lateral air flow height is set to 0.5m, the air outlet speed V1 of the main air curtain machine is set to 3m/S, the air speed attenuation is smaller because the door opening width is not large, S is set to 2m, namely the air speed reaching the lateral air flow position is set to 3m/S, the human body width H Human body is set to 0.4m, V1 = 3m/S, S = 2m, S1 and S2 are determined according to the positions of people, S1 is set when only one person exists, the distance between the leftmost person position (the position of the human body nearest to the left side of the door opening) and the left side of the door opening is set to S1, the distance between the right person position (the position of the human body nearest to the right side of the door opening) and the right side of the door opening is set to be S2, and then V2 is calculated.
Because the lateral air flow transversely sweeps the human body, V2 is two numerical values V21 and V22 (V21 is set to be more than V22), and the air outlet speed of the auxiliary air curtain machine is adjusted between V21 and V22, so that the purpose of transversely sweeping the human body is achieved (the calculation takes the center of the human body as a calculation point). When the wind outlet speed of the auxiliary air curtain machine is V21, the lateral air flow position is S11 (S11 is the distance between the air flow junction and the main air curtain machine), and when the wind outlet speed of the auxiliary air curtain machine is V22, the lateral air flow position is S22, and the following formula can be obtained:
when only one person passes through the door opening,
V1/V21＝S11/(S－S11)
＝(S1－H Human body /2－0.1)/(S－S1+H Human body /2+0.1)
＝(S1－0.3)/(S－S1+0.3)。
V1/V22＝S22/(S－S22)
＝(S1+H Human body /2+0.1)/(S－S1－H Human body /2－0.1)
＝(S1+0.3)/(S－S1－0.3)。
V21, V22 can be calculated from the above equation.
When a plurality of persons pass through the door opening,
V1/V21＝S11/(S－S11)
＝(S1－H Human body /2－0.1)/(S－S1+H Human body /2+0.1)
＝(S1－0.3)/(S－S1+0.3)。
V1/V22＝S22/(S－S22)
＝(S2+H Human body /2+0.1)/(S－S2－H Human body /2－0.1)
＝(S2+0.3)/(S－S2－0.3)。
V21 and V22 are calculated according to the above formula.
Assuming that there is only one person, substituting the person in the above formula at s1=1.1m position results in V21 and V22 of 4.5m/S and 1.29m/S, respectively. The wind speed is directly regulated at 4.5m/s and 1.29m/s. The height of the auxiliary air curtain machine can be designed according to actual demands, and the height can be set to be not lower than the knee position of a person as much as possible, so that the dust removal effect is ensured.
Based on the above analysis, after a person is identified to be close to the door opening and to be away from the door opening by a preset distance, the wind speed of the auxiliary air curtain machine is regulated and controlled according to the preset wind speed of the main air curtain machine and the distance between the human body and the two sides of the door opening, and the following preferred implementation manner can be realized: the wind speed of the auxiliary air curtain machine is calculated by the following formula: v1/v21=s1/(S-S1); v1/v22=s2/(S-S2); wherein V1 is the preset wind speed of the main air curtain machine, V21 is the first wind speed of the auxiliary air curtain machine, V22 is the second wind speed of the auxiliary air curtain machine, S is the width of the door opening, and S1 is the distance between a human body and one side of the door opening; s2 is the distance between the human body and the other side of the door opening; controlling the wind speed of the auxiliary air curtain machine to operate between the first wind speed and the second wind speed. Thereby ensuring that the lateral air flow formed by the opposite blowing is kept within a preset width range.
After a plurality of people are close to the door opening and are separated by a preset distance, the wind speed of the auxiliary air curtain machine is regulated and controlled according to the preset wind speed of the main air curtain machine and the distances between the human body and the two sides of the door opening, and the method can be realized by the following preferred embodiments: the wind speed of the auxiliary air curtain machine is calculated by the following formula: v1/v21=s11/(S-S11); v1/v22=s22/(S-S22); wherein V1 is the preset wind speed of the main air curtain machine, V21 is the first wind speed of the auxiliary air curtain machine, V22 is the second wind speed of the auxiliary air curtain machine, S is the width of the door opening, and S11 is the distance between the nearest human body position on one side of the door opening and one side of the door opening; s22 is the distance between the nearest human body position on the other side of the door opening and the other side of the door opening; controlling the wind speed of the auxiliary air curtain machine to operate between the first wind speed and the second wind speed. Thereby ensuring that the lateral air flow formed by the opposite blowing is kept within a preset width range.
