Referring to FIG. 8, first, the topography of the indoor space may be measured based on a location where each of the plurality of air circulation devices 200 is installed to generate spatial topographic information based on an installation location (S101). 8 illustrates that all of the plurality of air circulation devices 200 perform measurement and information generation, but the operation may be performed only by a device having a spatial topography detection means among the plurality of air circulation devices 200. .

In addition, the plurality of air circulation devices 200 may transmit the generated spatial topography information based on the installed location to the air circulation control device 100 (S102).

In addition, the air circulation control apparatus 100 may generate spatial topographic information by mapping the spatial topographic information of the installation location reference received from each of the plurality of air circulation devices 200 based on the location where the corresponding air circulation device is installed. (S103). Specifically, the spatial topographic information processing unit 130 corrects the position and shape of objects located in the indoor space from the spatial topographic information based on the installation position values of the air circulation devices, and combines the corrected data to obtain the final indoor spatial topography. Information can be generated. Here, the spatial topographic information may include location information of an object located in the indoor space.

In addition, the air circulation control apparatus 100 may determine the location of the object located in the indoor space using the spatial topographic information (S104).

In addition, the air circulation control apparatus 100 selects an air circulation apparatus that needs to be controlled among the plurality of air circulation apparatuses 200 based on the determined position of the object, and among the air exhaust intensity and the air discharge direction to the selected air circulation apparatus. A control signal for controlling at least one can be transmitted (S105). For example, the controlling step (S105) may include at least one of the air discharge intensity and the air discharge direction of the air circulation device that requires control among the plurality of air circulation devices so that air is not discharged toward the object based on the determined position of the object. Can be controlled.

Even in the control process of air discharge based on the spatial topographic information, the air circulation device 200 may form an air circulation ring in the indoor space 800 by performing air suction and purification of the sucked air.

On the other hand, when the air is discharged toward an object such as a person, furniture, etc. located in the indoor space 800, the air hits the object and spreads in all directions, making it difficult to form an air circulation loop. According to the present invention, the air circulation control device 100 controls at least one of the air discharge intensity and the air discharge direction of the air circulation device 200 based on the spatial topographic information. Therefore, the air is not discharged toward the object, thereby solving this problem and effectively forming an air circulation loop to manage indoor air quality.

In addition, the plurality of air circulation devices 200 may transmit the generated dust amount information to the air circulation control device 100 (S202).

In this case, the air circulation control apparatus 100 may determine whether the fine dust amount information is greater than or equal to a preset value (S203). If the fine dust amount information is smaller than the preset value (S203: N), the air circulation control device 100 may receive the dust amount information from the air circulation device 200 periodically in units of time. However, when the amount of dust information is larger than the predetermined value (S203: Y), it is possible to control to increase the air intake intensity of the air circulation device that needs to be controlled among the plurality of air circulation devices (S204). For example, the air circulation control apparatus 100 may control to increase the air intake intensity of the air circulation apparatus in which the amount of dust information is greater than or equal to a preset value, or the amount of dust calculated by combining the obtained amount of fine dust information may be a preset value. In the above case, it may be controlled to increase the air intake intensity of at least one air circulation device among the plurality of air circulation devices.

In this case, the air circulation device 200 receiving the control signal may perform a clean acceleration operation by increasing the air suction strength according to the control (S205).

If the amount of dust information is greater than a predetermined value (S208: N), the air circulation control apparatus 100 may periodically receive the amount of dust information from the air circulation apparatus 200 on a time basis. However, when the fine dust amount information is smaller than the preset value (S208: Y), the air circulation control device 100 lowers the air intake intensity of the air circulation device 200 in which the dust amount information is less than or equal to the preset value or defaults. It can be controlled to adjust the suction strength. Alternatively, when the amount of dust calculated by combining the obtained amount of fine dust information is equal to or less than a predetermined value, the air circulation control device 100 may lower the air intake intensity of at least one air circulation device among the plurality of air circulation devices or the default suction. It may be controlled to adjust the intensity (S210).

According to the inhalation intensity adjustment based on the amount of fine dust, the air circulation device 200 increases the air intake intensity to further inhale and purify the fine dust located around the device and at the same time discharge the sucked air into the indoor space 800. can do.

According to the present invention, the air circulation ring formed in accordance with the air intake and air discharge of the air circulation device 200 may prevent the fine dust from moving to accumulate in a predetermined area of the indoor space 800, at the same time air circulation Since the air suction strength of the device 200 can be increased to further inhale and purify the fine dust located around the device, the amount of fine dust in the indoor space 800 can be effectively lowered. In particular, instead of increasing the air intake intensity of all of the plurality of air circulation devices 200, a portion thereof is selected to adjust the intake intensity, thereby effectively consuming power and lowering the amount of fine dust in the indoor space 800. .
