Additionally, the management server 40 is connected to the ventilation controller 100 through the network 30 and can transmit and receive signals. Here, the network 30 is defined as a broad concept that includes not only the Internet but also mobile communication networks such as CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA), and LTE (Long Term Evolution).

The ventilator 10 is installed between the outdoors and indoors of the building and ventilates air from the outdoors to the indoors or from the indoors to the outdoors. At this time, a plurality of ventilation fans 10 may be installed facing outdoors in different directions. Although the drawings show the ventilators 10 installed in opposite directions, the ventilators 10 may be installed in various directions.

The indoor air collection sensor 20 collects indoor air. At this time, the indoor air collection sensor 20 can collect air within a set range for a set time from various locations indoors.

The management server 40 is connected to the ventilation controller 100 through the network 30, and receives information from the ventilation controller 100 about the status of indoor air in the building, status information about outdoor air around the building, and indoor air control. Information, etc. can be received and displayed, or a control signal by the manager can be transmitted to the ventilation controller 100 to control indoor air. In addition, the management server 40 can retrieve information about outdoor air in each region from the Korea Meteorological Administration, and transmit outdoor air information corresponding to the location of the ventilation controller 100 among the searched outdoor air information to the ventilation controller 100. there is.

The outdoor air collection sensor 50 collects outdoor air. At this time, the outdoor air collection sensor 50 can collect air within a set range for a set time from various locations outdoors within a set range from the building.

The ventilation controller 100 is based on indoor air information collected by the indoor air collection sensor 10, outdoor air information received through the management server 40, and outdoor air information collected by the outdoor air collection sensor 50. Thus, the ventilation of the ventilation fan 10 is adaptively controlled. At this time, when a plurality of ventilation fans 10 are installed, it is preferable that the ventilation controller 100 controls each ventilation fan 10 individually.

Here, as shown in FIG. 2, the ventilation controller 100 includes an air quality determination unit 102, an air information reception unit 104, a ventilation control unit 106, a filtering strength control unit 108, a transmittance measurement unit 110, It may include a replacement signal transmission unit 112 and a sterilization intensity control unit 114.

The air quality determination unit 102 determines indoor air quality based on the air collected by the indoor air collection sensor 10. At this time, the air quality determination unit 102 can determine the indoor air quality by analyzing the concentration of a specific chemical component in the indoor air collected by the indoor air collection sensor 10. For example, the air quality determination unit 102 determines formaldehyde, benzene, toluene, and ethylbenzene contained per unit volume in the indoor air collected by the indoor air collection sensor 10. Indoor air quality can be determined by analyzing the concentrations of xylene, stren, etc. For example, the air quality determination unit 102 measures the concentration of components such as formaldehyde, benzene, and toluene contained per unit volume, and determines the indoor air quality as one of a plurality of preset levels based on the concentrations of the measured components. can do. Additionally, when indoor air is collected from a plurality of indoor locations, the air quality determination unit 102 may determine the indoor air quality by calculating the average value of the indoor air for each collected location.

The air information receiving unit 104 receives air information including concentration of fine dust, wind direction, wind strength, etc. from the management server 40 connected through the network 30. At this time, the air information receiver 104 transmits the location information of the building where the ventilation controller 100 is installed to the management server 40, and can receive air information of the area corresponding to the location information.

The ventilation control unit 106 controls the ON/OFF and ventilation direction of the ventilation fan 10 based on the indoor air quality determined by the air quality determination unit 102 and the air information received by the air information receiving unit 104. and controlling the intensity of ventilation. That is, the ventilation control unit 106 controls the concentration of specific chemical components in the indoor air determined by the air quality determination unit 102, the concentration of fine dust in the outside air received by the air information receiving unit 104, the wind direction, and the wind. The on/off, ventilation direction, ventilation intensity, etc. of the ventilation fan 10 are controlled based on air information such as the intensity of the ventilation fan 10. At this time, when a plurality of ventilation fans 10 are installed in a building, the ventilation control unit 106 can individually control each ventilation fan 10 according to the comparison result of indoor air quality and outdoor air information. For example, as shown in FIG. 3, the wind blows from left to right with respect to the building, ventilators 10 are installed on the left and right sides of the building, and the fine dust concentration in the outdoor air is If the indoor air quality is lower than the set value and the concentration of a specific chemical component in the indoor air is determined to be lower than the set value and ventilation is necessary, the ventilation control unit 106 turns on the ventilator 10 on the left to blow outside air into the room. Ventilation can be controlled to allow indoor air to flow in, and the ventilation fan 10 on the right side can be controlled to allow indoor air to flow out to the outside. In this case, the ventilation control unit 106 may compare the concentration of a specific component of outdoor air with the concentration of a specific component of indoor air, and may control the ventilation direction and ventilation intensity of each ventilation fan 10 differently according to the difference. there is.

Meanwhile, the ventilator 10 may include a planar filter 60 for filtering air that flows into the room from the outside or flows out from the room to the outside. At this time, the planar filter 60 is provided with an air distribution hole 61 of a set size, as shown in FIG. 4. In addition, the ventilator 10 may be installed with a plurality of planar filters 60 overlapping each other, and each planar filter 66 can be moved by a set distance in the left, right, upward, or downward direction. there is.

The filtering strength control unit 108 controls the filtering strength of the area filter 60 based on the indoor air quality determined by the air quality determination unit 102 and the air information received by the air information receiving unit 104.

By adjusting the size of 61), the filtering strength of the circulating air can be controlled. For example, three planar filters 60 with air distribution holes 61 as shown in FIG. 4 are installed overlapping each other, and the filtering strength control unit 108 controls one of them to the left or By controlling the movement to the right by a set interval and controlling the other planar filter 60 to move by a set interval to the upper or lower side, the size of the air distribution hole 61 can be reduced and the filtering strength of the circulating air can be increased. However, the shape of the planar filter 60 shown in Figure 4 and the method of controlling the filtering strength using it are only examples to help understand the invention, and the circulating air can be filtered and the filtering strength can be controlled in various ways. there is.

In addition, the filtering strength control unit 108 operates the planar filter 60 installed in each ventilator 10 according to the concentration of specific chemical components in indoor air and the concentration of fine dust in external air determined by the air quality determination unit 102. The filtering strength of can be controlled differently. For example, in the case of the example shown in FIG. 3 described above, the filtering strength control unit 108 adjusts the planar filter 60 installed on the ventilator 10 on the left as the concentration of fine dust contained in the air flowing in from the outside increases. The filtering strength can be increased, and the higher the concentration of a specific chemical component contained in the indoor air, the filtering strength of the planar filter 60 installed on the right-facing ventilator 10 can be increased.

The transmittance measurement unit 110 periodically measures the transmittance of the planar filter 60 installed in the ventilator 10. At this time, the transmittance measuring unit 110 adjusts the size of the air distribution hole 61 of the planar filter 60 to be constant, and when the air volume is sent out at a set value from one side of the planar filter 60, the transmittance is transmitted to the other side. The transmittance can be determined by measuring the air volume. In addition, the transmittance measuring unit 110 can measure the transmittance for each size of the air distribution hole 61 while adjusting the size of the air distribution hole 61 of the planar filter 60 to be different from each other.

When the transmittance measured by the transmittance measuring unit 110 is less than or equal to a set value, the replacement signal transmission unit 112 sends the planar filter 60 installed in the ventilation fan 10 to the management server 40 through the network 30. Send a replacement signal. That is, the replacement signal transmission unit 112 controls the air distribution of the planar filter 60 when the transmittance of the planar filter 60, which is measured periodically, falls below a set value compared to the transmittance of the planar filter 60 in a normal state. It may be determined that the ball 61 is clogged, and accordingly, a replacement signal may be transmitted to the management server 40 to notify that the corresponding planar filter 60 needs to be replaced. At this time, when the replacement signal transmission unit 112 adjusts the sizes of the air distribution holes 61 of the planar filter 60 to be different from each other and measures the transmittance corresponding to each size, the average value of each measured transmittance is set. If the value is less than or equal to the value, a replacement signal for the corresponding planar filter 60 can be transmitted to the management server 40.

Meanwhile, the ventilator 10 may further include a sterilization treatment unit 62 that sterilizes air flowing into the room. At this time, the sterilization treatment unit 62 consists of a light generator that generates ultraviolet rays or infrared light, and as shown in FIG. 5, it can be installed on the planar filter 60 in a zigzag shape. In this case, the sterilization treatment unit 62 is preferably installed so as not to block the air circulation hole 61 of the planar filter 60.

The sterilizing intensity control unit 114 controls the sterilizing intensity of the sterilizing processing unit 62 based on the indoor air quality determined by the air quality determination unit 102 and the air information received by the air information receiving unit 104. That is, the sterilizing intensity control unit 114 can control the sterilizing intensity of the sterilizing treatment unit 62 installed in the ventilation fan 10 on the side where external air flows in according to the concentration of harmful components contained in the air flowing in from the outside. In addition, the sterilizing intensity control unit 114 may control the sterilizing intensity of the sterilizing treatment unit 62 installed in the ventilation fan 10 on the side that flows out to the outside according to the concentration of harmful components contained in the indoor air.

Meanwhile, since the air information received through the management server 40 is regional air information, it may be different from the air information in the area where the building is installed. The intelligent ventilation system according to an embodiment of the present invention installs outdoor air collection sensors 50 in a plurality of outdoor areas within a set range from the location where the building is installed, and measures air quality using each outdoor air collection sensor 50. , outdoor air information including wind direction, wind strength, etc. can be collected. In this case, the ventilation control unit 106 can secondarily control the on/off, ventilation direction, and ventilation intensity of the ventilation fan 10 based on the outdoor air information collected by each outdoor air collection sensor 50. . That is, the ventilation control unit 106 primarily controls the ventilation fan 10 based on the air information received from the management server 40, and controls the ventilation of the building based on the outdoor air information received from the outdoor air collection sensor 50. The ventilator 10 can be secondarily controlled according to the actual environment.

Figure 6 is a flowchart showing an indoor air quality management method according to an embodiment of the present invention. The indoor air quality management method according to an embodiment of the present invention can be performed by the ventilation controller 100 of the intelligent ventilation system shown in FIG. 1.

Referring to FIGS. 1 to 6 , a plurality of ventilation fans 10 may be provided facing outdoors in different directions for an indoor area where the air quality of a building is to be managed (S101).

The ventilation controller 100 determines indoor air quality based on the air collected by the indoor air collection sensor 10 (S103). At this time, the ventilation controller 100 can determine the indoor air quality by analyzing the concentration of a specific chemical component in the indoor air collected by the indoor air collection sensor 10. For example, the ventilation controller 100 detects formaldehyde, benzene, toluene, ethylbenzene, etc. contained per unit volume in the indoor air collected by the indoor air collection sensor 10. Indoor air quality can be determined by analyzing the concentration of xylene, stren, etc. Additionally, when indoor air is collected from a plurality of locations in the room, the ventilation controller 100 can determine the air quality of the room by calculating the average value of the indoor air for each collected location.

The ventilation controller 100 receives air information including the concentration of fine dust, wind direction, and wind strength from the management server 40 connected through the network 30 (S105). At this time, the ventilation controller 100 transmits the location information of the building to the management server 40 and can receive local air information corresponding to the location information.

The ventilation controller 100 controls the ON/OFF, ventilation direction, and intensity of the ventilation fan 10 based on the determined indoor air quality and air information received from the management server 40 (S107). . In other words, the ventilation controller 100 operates the ventilation fan based on air information such as the concentration of a specific chemical component in the indoor air determined and the concentration of fine dust in the external air received from the management server 40, the direction of the wind, and the intensity of the wind. (10) Controls on/off, ventilation direction, ventilation intensity, etc. At this time, when a plurality of ventilation fans 10 are installed in a building, the ventilation controller 100 can individually control each ventilation fan 10 according to the comparison result of indoor air quality and outdoor air information. For example, the wind is blowing from the left to the right of the building, the ventilator 10 is installed on the left and right sides of the building, the fine dust concentration in the outdoor air is low below the set value, and the indoor air is low. When the concentration of a specific chemical component exceeds a set value and the indoor air quality is determined to be lowered and ventilation is necessary, the ventilation controller 100 controls the left ventilation fan 10 to allow external air to flow into the room, and the right ventilation fan 10 controls the ventilation to allow external air to flow into the room. The ventilation fan 10 can control ventilation so that indoor air flows out to the outside. In this case, the ventilation controller 100 compares the concentration of a specific component in outdoor air with the concentration of a specific component in indoor air, and may control the ventilation direction and ventilation intensity of each ventilation fan 10 differently according to the difference. there is.

Meanwhile, the ventilator 10 may include a planar filter 60 for filtering air that flows into the room from the outside or flows out from the room to the outside.

You can. At this time, the ventilation controller 100 adjusts the size of the air distribution hole 61 formed by the plurality of planar filters 60 by moving each planar filter 60 to the left, right, upward, or downward. Thus, the filtering strength can be controlled (S109).

The ventilation controller 100 may control filtering of the area filter 60 of each ventilation fan 10 based on the determined indoor air quality and air information received from the management server 40 (S111). At this time, the ventilation controller 100 may control the filtering strength of the planar filter 60 installed in each ventilation fan 10 differently depending on the concentration of a specific chemical component in the indoor air and the concentration of fine dust in the external air. there is. For example, the ventilation controller 100 can increase the filtering strength of the planar filter 60 installed in the ventilator 10 on the left as the concentration of fine dust contained in the air flowing in from the outside increases, and can increase the filtering strength of the planar filter 60 installed in the ventilator 10 on the left side. The higher the concentration of the specific chemical component included, the higher the filtering strength of the planar filter 60 installed in the ventilator 10 on the right side.

The ventilation controller 100 periodically measures the transmittance of the planar filter 60 installed in the ventilation fan 10 (S113). At this time, the ventilation controller 100 constantly adjusts the size of the air distribution hole 61 of the planar filter 60, and when the air volume is sent out at a set value from one side of the planar filter 60, the air volume transmitted to the other side is By measuring the wind volume, the transmittance can be judged. In addition, the ventilation controller 100 can measure the transmittance for each size of the air distribution hole 61 while adjusting the size of the air distribution hole 61 of the planar filter 60 to be different from each other.

If the measured transmittance is below the set value, the ventilation controller 100 transmits a replacement signal for the planar filter 60 installed in the ventilation fan 10 to the management server 40 through the network 30 (S115). That is, when the transmittance of the planar filter 60, which is measured periodically compared to the transmittance of the planar filter 60 in a normal state, falls below the set value, the ventilation controller 100 operates the air distribution hole of the planar filter 60 ( 61) may be determined to be clogged, and accordingly, a replacement signal may be transmitted to the management server 40 to notify that the corresponding planar filter 60 needs to be replaced. At this time, when the ventilation controller 100 adjusts the sizes of the air distribution holes 61 of the planar filter 60 differently and measures the transmittance corresponding to each size, the average value of each measured transmittance is less than or equal to the set value. In this case, a replacement signal for the corresponding planar filter 60 can be transmitted to the management server 40.

Meanwhile, the ventilator 10 may further include a sterilization treatment unit 62 that sterilizes air flowing into the room. At this time, the sterilization treatment unit 62 consists of a light generator that generates ultraviolet or infrared light, and may be installed on the planar filter 60 in a zigzag shape. In this case, the sterilization treatment unit 62 is preferably installed so as not to block the air circulation hole 61 of the planar filter 60.

The ventilation controller 100 controls the sterilization intensity of the sterilization processing unit 62 based on the determined indoor air quality and air information received from the management server 40 (S117). That is, the ventilation controller 100 can control the sterilization intensity of the sterilization treatment unit 62 installed in the ventilation fan 10 on the side where external air flows in according to the concentration of harmful components contained in the air flowing in from the outside. In addition, the ventilation controller 100 may control the sterilization intensity of the sterilization treatment unit 62 installed in the ventilation fan 10 on the side that flows out to the outside according to the concentration of harmful components contained in the indoor air. The ventilation controller 100 individually controls the sterilization treatment of each ventilation fan 10 through the adjusted sterilization intensity of each ventilation fan 10 (S119).

Meanwhile, since the air information received through the management server 40 is regional air information, it may be different from the air information in the area where the building is installed.
