Smart air purifier control system using Internet of Things (IOT) {SMART AIR PURIFIER CONTROL SYSTEM USING IOT}

The present invention relates to a smart air purifier control system using the Internet of Things (IOT), and more particularly, by selectively operating the air purifier provided for each zone in the subway according to the request of the passenger to prevent unnecessary operation of the air purifier and power consumption And, it relates to a smart air purifier control system using the Internet of Things (IOT) that can quickly purify air by driving a hot and cold fan that can disperse purified air to the surroundings.

In general, it is difficult to ventilate an underground space such as the inside of a subway because outside air flows in, and the dust generated inside the subway or fine dust introduced to the outside floats inside the underground space, so the air is turbid and has a high degree of pollution. exist.

Accordingly, an air purifier for purifying the internal air of the underground space is provided in the subway internal space for each predetermined area.

Such air purifiers have a problem in that it is difficult to quickly purify the air according to the commute time when passengers are crowded, because the operating time is simply controlled according to the subway operating hours and it is difficult to control the degree of operation.

As a prior art for solving the above-mentioned problems, "subway station air purification ventilation system" is disclosed in Korean Patent Registration No. 10-0658822.

However, the prior art also allows the on-site manager to remotely control the power supply of the multiplier and dust collector to perform an air cleaning function, and it is rather difficult to drive the air purifier according to the air pollution level experienced by passengers, and to provide more purified air. There is an inconvenience that it is rather difficult to provide customized purified air to passengers who want to obtain it.

In addition, since the air purification ventilation system including the multiplier and the dust collector purifies only the air in the space adjacent to the multiplier and the dust collector, the further away from the multiplier and the dust collector, the lower the air quality, and the purified air is stored in the underground space. It is difficult to circulate the air inside the subway station, so it is difficult to purify the air inside the subway station as a whole.

1 and 2 schematically show the configuration of a smart air purifier control system using the Internet of Things (IOT) according to the present invention, Fig. 3 shows a management unit according to the present invention, and Figs. It shows the interface implemented in the user terminal.

The present invention prevents unnecessary operation of the air purifier and power consumption by selectively driving the air purifier provided for each zone in the subway according to the request of the passenger, and also drives the hot and cold fan capable of distributing the purified air to the surroundings to provide faster airflow. To a smart air purifier control system using the Internet of Things (IOT) that can purify (400).

The air purifier 100 is a device for purifying air, and operation may be controlled by the management unit 300 . The air purifier 100 is remotely controlled by the management unit 300 , and may be driven according to a passenger's air purification request received by the management unit 300 .

The hot and cold blower 200 is installed adjacent to the air purifier 100, and can control the indoor temperature in the subway station by discharging cold and/or hot air, as well as converting the purified air discharged from the air purifier 100 to the air purifier ( 100), exhaust the wind so that it can spread farther away so that the purified air can be circulated to the underground space.

At this time, the hot and cold blower 200 is most preferably installed at the outlet side through which the air purifier 100 discharges the purified air so as to circulate the purified air of the air purifier 100 quickly, but is not limited thereto.

The above-described air purifier 100 and cold/hot air blower 200 may be equally installed as a single unit for each predetermined area A, and the air purifier 100 provided for each area A1, A2, ..., An, and The cold/hot air blower 200 may be controlled by the management unit 300 for each zone.

This zone (A) can be arbitrarily divided according to the location where the air purifier 100 and the hot and cold fan 200 are installed, and preferably, the air purifier installed along the screen door and the zone divided by the door of the subway. (100) and the hot and cold blower (200) and to set the adjacent area.

The management unit 300 receives an air purification request signal from the user terminal 400 carried by the passenger and controls the operation of the air purifier 100 and the cold/hot air blower 200, the communication module 310, the control module 320 , a determination module 330 and a memory 340 .

The communication module 310 is connected to the user terminal 400 to receive an air purification request signal from the user terminal 400 , and a separate server is provided so that it can be connected to the user terminal 400 .

The communication module 310 includes an interface providing unit 311 that provides an interface through which a passenger can request air purification using a QR code in a subway station.

The interface providing unit 311 provides an interface (I) that can perform an air purification request when the passenger is connected to the communication module 310 through the user terminal 400 as shown in FIGS. 4 and 5 to download a separate application, etc. This makes it unnecessary and simple to perform an air purification request.

The interface I provided by the interface providing unit 311 is provided with an input box for directly inputting the age of the passenger, whether the patient is a bronchial patient, and the degree of air purification.

The control module 320 receives, from the determination module 330, a determination value on whether the air purifier 100 and the cold/hot air blower 200 are driven and the degree of operation, according to which the air purifier 100 provided in each zone (A). and the cold and hot air fan 200 are remotely driven and controlled.

When the determination module 330 receives the air purification request signal through the communication module 310, it analyzes the air purification request signal and the air purifier provided in the area A where the user terminal 400 that has transmitted the air purification request signal is located. (100) and the cold/hot air blower (200) performs a function of determining whether to drive and the degree of driving, and transmits the generated determination value to the control module (320).

On the other hand, if the driving degree of the air purifier 100 is controlled at the request of one passenger, the power consumption of the air purifier 100 may be rather large. ), there is a need to adjust the driving status and driving degree. For example, when one passenger requests air purification in the same way, when there are many passengers such as commuting time and when there are few passengers such as late night time, the driving degree of the air purifier 100 and whether the cold/hot air fan 200 is driven and There is a need to appropriately adjust the driving degree.

Accordingly, the determination module 330 according to the present invention can solve the above-described problems, including the count unit 331 , the weight unit 332 , and the drive determination unit 333 . This will be described with reference to FIG. 3 .

First, the count unit 331 receives the air purification request from the management unit 300 through the user terminal 400 through the communication module 310 and counts it.

This counting unit 331 counts only the number of air purification requests, as well as the corresponding area of the passenger who sent the air purification request, the air purification request reception time, the request value for the degree of air purification, the passenger's unique identification value, that is, the passenger You can count the number of requests, including by age group, passenger status (whether normal or bronchial patient), etc., and check the contents of the air purification request.

The air purification request counted by the count unit 331 may give weight to the air purification request through the weight unit 332 .

The weight unit 332 performs a function of assigning weights according to the air purification request for each passenger and each time period received from the count unit 331 .

First, weights may be assigned according to age of passengers. For example, when an infant aged 0-5 and an elderly person over 60 who are vulnerable to polluted air perform an air purification request, a weight is assigned to the request value. At this time, in the case of infants or the elderly, when a guardian applies for an application, when a passenger using the user terminal 400 enters the identification value of an infant or the elderly including themselves and applies for air purification, the application value and weight of the general public are given. The application value of the elderly is added up.

In addition, in the case of a bronchial-related patient in addition to the age group of the passenger, his/her condition may be input into the interface I provided from the interface providing unit 311 in the communication module 310 using the user terminal 400, and this Through this, a weight can be assigned to the request value of the bronchial-related patient.

In addition, it is possible to give weight to the application value for requesting air purification during commuting time, which is a time zone with a large number of passengers. In this case, the start time may be set to 7:00 am to 10:00 am, and the leave time to be set from 5:00 pm to 8:00 pm.

In addition, when requesting air purification, a weight can be assigned according to the request for the degree of air purification. For example, when the interface (I) for the degree of air purification in normal, weak, and strong states is provided to the user terminal 400 as shown in FIG. 4 , the user sets the desired degree of air purification and then applies for air purification. and a weight corresponding to the strong state may be assigned.

Accordingly, as described above, examples of weights given to the request value 'R' may be set as shown in Table 1 below.

passenger status request value normal adult R Infant/Senior 1.5R bronchial patient 2R Request for commuting time 1.5R Air purification level 'weak' request 1.5R Request for ‘strong’ air purification degree 2R

The driving determination unit 333 controls the driving degree of the air purifier 100 through the summation of the request values weighted by the weighting unit 332 or adjusts whether the cold/hot air blower 200 is driven and the driving degree. do.

That is, as an example according to the criteria according to Table 1, when a bronchial patient requests air purification in a 'normal' state at 9:00 am (corresponding to rush hour), the total request value is 3.5R.

The request value may be determined to be able to control the air purifier 100 and the cold/hot air blower 200 according to a reference value preset in the driving determination unit 333, and the reference value is shown in Table 2 below.

Request value (R) 0 to 1 1.5 to 3.5 4 to 5 5.5 ~
driving state Maintaining the operating state of the existing air purifier Controls the driving degree of the air purifier in proportion to the requested value Start of cold/hot fan operation Controlling the degree of operation of the cold/hot fan in proportion to the requested value

Therefore, as described above, when the total request value is 3.5R, the driving degree of the air purifier 100 is maintained in the highest driving state, but the driving of the cold/hot air blower 200 is maintained in a stopped state.

In addition, the driving determination unit 333 is driven according to the summed request values requested from various passengers within a predetermined time, and the predetermined time is preferably set to 15 minutes, but is not limited thereto.

As described above, the weighting unit 332 gives weights of the requested values requested from various passengers within a certain period of time, and the driving determination unit 333 determines the driving degree of the air purifier 100 according to the reference value according to the summed request value. To control or control whether the cold and hot air fan 200 is driven and the degree of driving.

At this time, the predetermined time is initialized every minute, and the request values requested in the past from the current time are summed at the current time to control the driving degree of the air purifier 100 disposed in the corresponding area (A), and, if necessary, By controlling whether the cooling fan 200 is driven and the degree of driving, the air purified from the air purifier 100 can be quickly circulated inside the subway station.

In the memory 340 , the interface I included in the communication module 310 , the weighting value of the weighting unit 332 , the reference value of the determination module 330 , etc. are pre-stored in the memory 340 . By using the value, the management unit 300 can control the operation of the air purifier 100 and the cold/hot air blower 200 .

The user terminal 400 may be a smartphone, tablet PC, etc. personally owned by the passenger, and the communication module 310 in the management unit 300 through the QR code provided in the air purifier 100 installed for each area in the subway station. can be connected to, and implements the interface (I) as the user terminal 400 through the interface providing unit 311 so that the air purification request can be performed.

On the other hand, there are times when additional driving of the air purifier 100 is required even when the passenger does not receive an air purification request through the interface I implemented in the user terminal 400 . For example, due to the wind generated when a subway enters or departs, a large amount of fine dust can move and float in the subway station, and the air pollution in the subway station is relatively high during the time period used by a large number of passengers, such as commuting time.

In this case, there is a problem in that it is difficult to provide improved air quality because the air purifier 100 and the cold/hot air blower 200 are generally driven until the passenger directly requests it.

In addition, there is a problem in that it is difficult for the passenger to determine whether or not to drive the air purifier because the current indoor air pollution level cannot be informed to the passenger through the user terminal 400 .

Accordingly, in order to solve the above-described problems, the smart air purifier control system 1 according to the present invention may further include a sensing unit 500 capable of determining the degree of pollution of the air in the subway station.

The detection unit 500 includes a sensor capable of detecting the air pollution level, and detects the pollution level of the air in which the detection unit 500 is installed, and transmits it to the management unit 300 .

At this time, since the sensing unit 500 is installed in a space separated from the air purifier 100 , it is possible to detect the average air pollution level for each zone rather than detecting the purified air around the air purifier 100 . Such a sensing unit 500 is provided on an indoor bench or a screen door where passengers are mainly located to detect the pollution level of air that passengers mainly come into contact with. to control the operation of

In addition, the sensing unit 500 measures the temperature of the area in which the sensing unit 500 is installed, including the temperature sensor, and determines the measured temperature sensor value and the appropriate indoor temperature for each season stored in the memory 340 in advance. ), the control module 320 controls the temperature of the wind discharged by the cold and hot air blower 200 to drive the cold and hot air blower 200 .

For example, if the current temperature of the first zone A1 is 20°C and the appropriate indoor temperature for that day is 25°C, the control module can discharge wind having a temperature of 25°C or higher when the cold/hot air blower 200 is driven Controlled by 320, the wind along with the purified air can circulate in the space in the subway station, and by providing an appropriate indoor temperature to the passengers, it is possible to use the subway station more comfortably.

Furthermore, through the sensing unit 500, the temperature and air pollution degree values for each zone are guided to the user terminal 400 possessed by the passenger, so that even if the driving of the air purifier 100 is not requested, the clean area adjacent to the passenger is located. Alternatively, it is possible to guide the user to move directly to the second zone A2, etc., which is a zone having a desired indoor temperature, thereby preventing additional driving of the air purifier 100 and the cold/hot air blower 200 .

Furthermore, the sensing unit 500 detects a difference between a preset value in the memory 340, that is, a certain range for the average indoor temperature and average air pollution for each season, and the current indoor temperature and air pollution in the subway station. Determination module 330 This automatically compares the detected value detected by the sensing unit 500 with a preset value in the memory 340 to automatically match the average indoor temperature and average air pollution level for each season without a passenger's request. 200) can be automatically controlled.
