4 is a diagram showing a method of monitoring and ventilating the surrounding environment by the integrated IOT wireless electronic classroom according to the present embodiment.

As shown in FIG. 4, the integrated electronic classroom 100 collects indoor environment information and outdoor environment information from the indoor environment information collection unit 400 and the outdoor environment information collection unit 405, and air conditioning based on the collected information. Perform the action.

Referring to FIG. 4, the indoor environment information collection unit 400 may be implemented inside a space capable of collecting environment information in a smart classroom, and the outdoor environment information collection unit 405 may collect outdoor environment information. It can be implemented outside the space. The indoor environment information collection unit 400 and the outdoor environment information collection unit 405 may transmit indoor environment information and outdoor environment information to the environment monitoring unit 360 based on wired and/or wireless. The indoor environment information collection unit 400 and the outdoor environment information collection unit 405 may be plural. For example, the indoor environment information collection unit 400 may be plural, and may be positioned at each of a plurality of places within the indoor space to sense a current state and change of the quality of indoor air in a plurality of indoor spaces.

The environment monitoring unit 360 may collect indoor environment information and outdoor environment information, and determine an operation of the air conditioning unit based on the indoor environment information and the outdoor environment information. For example, the indoor environment information may include indoor dust information and indoor harmful gas information, and the outdoor environment information may include outdoor dust information and outdoor harmful gas information.

Indoor dust information and indoor harmful gas information is an example of lower indoor environment information, and outdoor dust information and outdoor harmful gas information may be an example of lower outdoor environment information. In the present embodiment, the operation of the air conditioner may be determined based on various other lower indoor environment information and lower outdoor environment information.

The environmental monitoring unit 360 includes a first threshold set for the indoor dust concentration 430 indicated by the indoor dust information and a second threshold set for the indoor harmful gas concentration 440 indicated by the indoor harmful gas information The indoor air quality can be judged based on.

When the current indoor dust concentration 430 exceeds the first threshold and/or the current indoor harmful gas concentration 440 exceeds the second threshold, the environmental monitoring unit 360 indicates that indoor air replacement is necessary. You can decide.

When it is determined that indoor air replacement is necessary, the environment monitoring unit 360 may determine whether to perform a first blowing operation or a second blowing operation based on outdoor environment information. As described above, the first blowing operation 470 may be an operation of introducing outdoor air into the room, and the second blowing operation 480 may be an operation of blowing indoor air to the outside.

The environmental monitoring unit 360 performs a first blowing operation based on the outdoor dust concentration 450 indicated by outdoor dust information included in outdoor environment information and the outdoor harmful gas concentration 460 indicated by outdoor harmful gas information. It may be determined whether to perform the second blowing operation 480 or 470.

When the current outdoor dust concentration 450 included in the outdoor dust information is less than the first threshold value and the current outdoor harmful gas concentration 460 included in the outdoor harmful gas information is less than the second threshold value, the environmental monitoring unit 360 Outdoor air may be introduced into the room by performing the first blowing operation 470. That is, since the outdoor air quality is relatively better than the indoor air quality, the environmental monitoring unit 360 may perform the first blowing operation 470 to introduce outdoor air into the room.

Conversely, when the current outdoor dust concentration 450 included in the outdoor dust information exceeds the first threshold value or the current outdoor harmful gas concentration 460 included in the outdoor harmful gas information exceeds the second threshold value, the second blowing By performing operation 480, an operation of discharging indoor air to the outside may be performed. That is, since the quality of the outdoor air is relatively worse than that of the indoor air, the environmental monitoring unit 360 performs the second blowing operation 480 to discharge the current indoor air and introduce other indoor air into the space.

The environment monitoring unit 360 may adaptively control the blowing operation by collecting indoor environment information and outdoor environment information after starting the first blowing operation 470 and the second blowing operation 480.

The time point at which it is determined whether to perform the first blowing operation 470 or the second blowing operation 480 based on the above-described determination may be reset, and the blowing operation after the reset is the first blowing operation (reset). , May be expressed in terms of a second blowing operation (reset).

The operation of the air conditioning system after the first blowing operation (reset) started in FIG. 5 and the operation of the air conditioning system after the second blowing operation (reset) started in FIG. 6 may be performed again after the reset point. .

The reset point is set based on the point in time when indoor air quality is not improved despite the operation of the air conditioning system after the first blowing operation (reset) and the operation of the air conditioning system after the second blowing operation (reset) starting in FIG. Can be.

The reset time is continuously increased based on the time when the indoor air quality is not improved according to the number of repetitions of the reset, so that when there is no change in indoor air quality, the air conditioning system is unnecessarily operated and unnecessary power consumption can be prevented.

5 is a diagram showing a method of performing an air conditioning operation by monitoring the surrounding environment of the integrated IOT wireless electronic classroom according to the present embodiment.

As shown in FIG. 5, the integrated electronic classroom 100 adaptively operates the air conditioning system after starting the first blowing operation (reset). Referring to FIG. 5, when the first blowing operation (reset) 550 is performed, outdoor air may be introduced, and the environment monitoring unit 360 receives indoor environment information from the indoor environment information collection unit, and Changes in environmental information can be judged.

The environmental monitoring unit 360 includes indoor dust concentration (before performing the first blowing operation) and indoor harmful gas concentration (before performing the first blowing operation) included in the indoor environment information before performing the first blowing operation (reset) 550 After performing the first blowing operation (reset) 550, the indoor dust concentration included in the indoor environment information (after performing the first blowing operation) and the indoor harmful gas concentration (after performing the first blowing operation) are compared to determine the indoor air quality. You can judge the degree of improvement.

The environment monitoring unit 360 may determine the air change during the set first threshold time 510 after the first blowing operation (reset) 550 is performed. The first critical time 510 is an initial time after the first blowing operation (reset) 550, and during the first critical time 510, the first critical time 510 continues to deteriorate the indoor air quality within the set first critical range 515. The blowing operation (reset) 550 can be maintained.

If there is a deterioration in indoor air quality above the first threshold range 515 during the first critical time 510, the first blowing operation (reset) 550 is temporarily stopped, and the second blowing operation 570 is performed. Can be done. The second blowing operation 570 is performed during the second critical time 720, and the environment monitoring unit 360 determines the air change during the set second critical time 720 after the second blowing operation 570 is performed. can do.

The second critical time 720 is an initial time after the second blowing operation 570, and during the second critical time 720, the second blowing operation continues to deteriorate the indoor air quality within the set second critical range 525 ( 570) can be maintained.

If there is a deterioration in indoor air quality above the second threshold range 525 during the second critical time 720, the second blowing operation 570 is switched back to the first blowing operation 590, and the first blowing operation The air change during the first threshold time 510 set to 590 may be determined again. In this way, the blowing operation switching repetition (n times) 595 in which the first blowing operation and the second blowing operation are continuously repeated is performed, so that the blowing operation of improving indoor air quality is selected. When the air quality deteriorates without improvement as described above, the first blowing operation and the second blowing operation are repeated for a set n times, and the blowing operation may be stopped after n times.

The n times may be determined based on the difference between indoor air quality and outdoor air quality (the difference between the indoor dust concentration and the outdoor dust concentration, and the difference between the indoor harmful gas concentration and the outdoor harmful gas concentration). The smaller the difference between the indoor air quality and the outdoor air quality, the smaller the size of n, and the larger the difference between the indoor air quality and the outdoor air quality, the larger the size of n may be.

Conversely, when there is no deterioration in indoor air quality above the first critical range 515 during the first critical time 510, the first blowing operation 560 may be performed in consideration of a change in indoor air quality. During the first critical time period 510, when the indoor air quality below the first critical range 515 deteriorates, or when the indoor air quality is improved, 1) when the indoor air quality is improved, 2) when the indoor air quality is maintained, 3) It may include a case where the indoor air quality deteriorates within the first critical range.

1) When indoor air quality is improved, 2) When indoor air quality is maintained, the environment monitoring unit 360 maintains the first blowing operation, but the speed of the first blowing operation may be increased.

When the air quality deteriorates within the first critical range 515, the environmental monitoring unit 360 maintains the first blowing operation 560, but sets an additional third critical time 530 to determine whether the air quality deteriorates. You can make additional judgments about it. When deterioration occurs within the second critical range 525 during the third critical time 530, the environmental monitoring unit 360 stops the first blowing operation 560 and switches to the second blowing operation 570. can do. The third critical range 530 may be set to a range smaller than the first critical range 515 so as to be switched to the second blowing operation 570 faster than when air quality does not change.

When deterioration occurs within the second critical range 525 during the third critical time 530, the environmental monitoring unit 360 may stop the first blowing operation 560 and switch to the second blowing operation. . In this case, as described above, the switching operation may be repeatedly performed between the aforementioned first blowing operation and the second blowing operation, similarly, the switching operation may be repeated for a set n times, and the blowing operation may be stopped after n times. .

According to the present embodiment, when the air purifying function is possible in the air conditioner, when there is a deterioration in indoor air quality of more than the second critical range 525 during the second critical time 720 and the third critical time 530. 2 When deterioration occurs within the critical range 525, the air purification function may be performed. As described above, the air purification function may be performed immediately, or the air purification function may be performed after x times of the set n times. At this time, the value of x may be determined in consideration of the degree of deterioration of air quality.

6 is a diagram showing a method of performing an air conditioning operation by monitoring the surrounding environment of the integrated IOT wireless electronic classroom according to the present embodiment.

As shown in FIG. 6, the integrated electronic classroom 100 adaptively controls a first blowing operation and a second blowing operation when indoor air replacement is required. In particular, after the integrated electronic classroom 100 starts the second blowing operation (reset), a method of adaptively operating the air conditioning system is disclosed.

Referring to FIG. 6, the second blowing operation is an operation of discharging indoor air to the outside, and air introduced when indoor air is discharged may be other indoor air.

When there is local air pollution, the second blowing operation may be effective, and when the overall indoor air quality is poor, the second blowing operation may not be effective.

After the second blowing operation (reset) 650 is performed, the environment monitoring unit 360 may determine the air change during the set fourth threshold time 610. The fourth critical time 610 is an initial time after the second blowing operation (reset) 650, and during the fourth critical time 610, even if the indoor air quality within the set third critical range 630 is deteriorated, the second It can maintain the blowing operation.

The fourth threshold time 610 may be set to be relatively longer than the aforementioned first threshold time. When there is no inflow of outside air, it is possible to judge the change in air quality for a relatively longer time with respect to the change in air quality.

If there is a deterioration in indoor air quality above the third threshold range 630 during the fourth critical time 610, the second blowing operation may be temporarily stopped. Unlike the case of FIG. 3, the current outdoor air quality is worse than the indoor air quality, and the first blowing operation may not be performed. In this case, the environmental monitoring unit 360 continuously receives the outdoor environment information, and when the outdoor air quality determined based on the outdoor environment information has a relatively better value than the indoor air quality determined based on the indoor environment information, the first It is also possible to perform a blowing operation.

In addition, the environment monitoring unit 360 may perform a second blowing operation 670 again after a set interruption time to perform a judgment on a change in indoor air quality.

Conversely, if there is no deterioration in indoor air quality above the third critical range 630 during the fourth critical time 610, if the indoor air quality within the third critical range 630 is deteriorated, or if there is no change in the indoor air quality, There may be cases where indoor air quality is improved.

When the indoor air quality deteriorates below the third threshold range 630 or when the indoor air quality is improved, the second blowing operation 660 may be continuously performed.

When the indoor air quality within the third critical range 630 is deteriorated, the environmental monitoring unit 360 maintains the second blowing operation 660, but sets the fifth critical time 620 to determine whether the air quality is deteriorated. You can judge. When deterioration occurs within the fourth critical range 610 during the fifth critical time 620, the environmental monitoring unit 360 may stop the second blowing operation 660.

In this case, similarly, when the environmental monitoring unit 360 continuously receives outdoor environment information and the outdoor air quality determined based on the outdoor environment information has a relatively better value than the indoor air quality determined based on the indoor environment information, the 1 Can perform the blowing operation. In addition, the environmental monitoring unit 360 may perform a second blowing operation again after a set interruption time to perform a judgment on a change in indoor air quality.

7 is a diagram illustrating a method of adaptively performing an air conditioning operation according to spatial characteristics while an integrated IOT wireless electronic desk according to the present embodiment monitors the surrounding environment.

In FIG. 7, a method for performing an air conditioning operation in consideration of spatial characteristics by adjusting a critical range and a critical time is disclosed. Referring to FIG. 7, the critical range 700 may be adjusted according to the location of the indoor environment information collection unit, the location of the air conditioning unit, the size of the indoor space, and the blowing performance. As the location of the indoor environment collection unit and the location of the air conditioning unit are relatively farther away, the change to the air may be relatively slow.

The threshold range 700 may be set to a relatively large value as the location of the indoor environment collection unit and the location of the air conditioning unit are relatively farther away. The critical time 720 may be set to a relatively large value as the location of the indoor environment collection unit and the location of the air conditioning unit are relatively farther away. In addition, as the size of the indoor space increases, the change to the air may be relatively slow.

Accordingly, the threshold range 700 may be set to a relatively large value as the size of the indoor space increases. The threshold time 720 may be set to a relatively large value as the size of the indoor space increases.

In addition, according to an embodiment of the present invention, the critical time 720 and the critical range 700 may be adaptively adjusted for each space in consideration of a reaction of air changes. In a situation in which the difference between indoor air quality and outdoor air quality is greater than or equal to the threshold value, the first threshold range, the second threshold range, and the first threshold time to the third threshold time may be determined based on the degree of change in indoor air quality when performing the first blowing operation. .

When performing the second blowing operation, the indoor air quality change data may be monitored to determine the third critical range, the fourth critical time, and the fifth critical time in consideration of the median or average value of the change time.

8 is a diagram showing a method of performing an air conditioning operation by monitoring the surrounding environment of the integrated IOT wireless electronic classroom according to the present embodiment.

As shown in FIG. 8, the integrated electronic classroom 100 performs a blowing operation in consideration of additional temperature information when indoor air replacement is required. Referring to FIG. 8, the indoor environment information may further include indoor temperature information 810, and the outdoor environment information may further include outdoor temperature information 820.

When the actual blowing operation is in progress, the environmental monitoring unit 360 may adjust the ventilation speed in consideration of the indoor temperature and the outdoor temperature. For example, when the outdoor temperature is low, such as in winter, outside air may be introduced due to the blowing operation and heating efficiency may be lowered.

Accordingly, there is a need for a method for preventing the internal temperature from rapidly changing by adjusting the speed of the ventilation air in consideration of the indoor temperature and the outdoor temperature in the air conditioning system.

When the indoor temperature and the outdoor temperature differ by more than a set threshold, the environmental monitoring unit 360 may determine that heating or cooling is performed indoors, and adjust a criterion of a determination threshold related to blowing and/or a speed of blowing. .

As described above, the environmental monitoring unit 360 may determine that indoor air replacement is necessary when the current indoor dust concentration exceeds the first threshold value and/or the current indoor harmful gas concentration exceeds the second threshold value. have.

The first threshold value and the second threshold value may be adjusted according to the difference between the indoor temperature and the outdoor temperature. That is, when the difference between the indoor temperature and the outdoor temperature is relatively large, cooling and heating efficiency may be considered by setting the first threshold value and the second threshold value relatively large in consideration of heating and cooling efficiency. When the difference between the indoor temperature and the outdoor temperature occurs within the critical temperature range 830, a first threshold value and a second threshold value may be set as default values, and the difference between the indoor temperature and the outdoor temperature is the critical temperature range 830 ) Or more, the first threshold and the second threshold may be increased based on a log function. That is, even if the difference between the indoor temperature and the outdoor temperature is large, by setting the first threshold value and the second threshold value above a predetermined level not to increase above a predetermined level, indoor air quality can be managed through air circulation.

In the first graph 850, an increase in a first threshold value and a second threshold value according to a temperature difference is started.

Further, according to an embodiment of the present invention, the blowing speed may be determined according to the temperature difference. When the difference between the indoor temperature and the outdoor temperature occurs within the critical temperature range 830, the first blowing operation and the second blowing operation may be performed at a set default blowing speed.

When the difference between the indoor temperature and the outdoor temperature exceeds the critical temperature range 830, a decrease in the blowing speed may be defined based on a log function. That is, as the temperature difference increases, the blowing speed is set weaker, but the degree of change in the blowing speed is continuously reduced so that the indoor air quality can be changed based on the blowing.

In the second graph 860, the degree of reduction of the blowing speed according to the temperature difference is started.

When the blowing speed is changed, the above-described first critical time to the fifth critical time may be lengthened according to the change of the blowing speed. As the blowing speed is relatively reduced, the first and fifth critical times may be relatively longer.

The above description is merely illustrative of the technical idea of the present embodiment, and those of ordinary skill in the technical field to which the present embodiment belongs will be able to make various modifications and variations without departing from the essential characteristics of the present embodiment.
