Recently, as a large amount of fine dust containing toxic substances and heavy metals discharged when burning fossil fuels is introduced into the air, air pollution has emerged as a social problem.

Fine dust particles are very small and are not easily filtered out. In some cases, they penetrate deep into the body and cause a risk of various diseases. In particular, families with children or the elderly are vulnerable to respiratory diseases, so attention should be paid to air pollution caused by fine dust.

Recently, since many air cleaners that can be used indoors are widely distributed, relatively clean air may be encountered indoors even when the external fine dust concentration is increased. However, in outdoor spaces other than indoors, they are still exposed to high dust concentration air. Furthermore, high concentrations of fine dust appear in certain seasons and weather conditions are very dangerous for the human body.

If there are many users of public transportation, such as large cities, many of the large populations are difficult to avoid exposure to external fine dust. In particular, since the bus user has to wait for a certain time at the bus stop located outdoors, they are exposed to the air contaminated by fine dust. In addition, since bus stops are close to buses, bus users are at risk of being exposed to polluted air with relatively high concentrations of fine dust and the like.

Accordingly, the method may be performed in the control method of the bus shelter 1 described later.

Hereinafter, a method of controlling the bus shelter 1 will be described in detail with reference to FIGS. 4 and 5. 4 is a flowchart illustrating a method of controlling the bus shelter 1 when the fine dust concentration inside the bus shelter 1 is not lowered even by the operation of the air curtain devices 200 and 400 and the ventilation device 300. FIG. 5 is a flowchart showing a control method of the bus shelter 1 which lowers the fine dust concentration inside the bus shelter 1 while efficiently using electric power.

Referring to FIG. 4, the control method of the bus shelter 1 is a control method for a case where a bus user or a bulky luggage is placed under the air curtain devices 200 and 400 to interfere with the air curtain. In this case, even when the air curtain apparatuses 200 and 400 and the ventilation apparatus 300 are operated, fine dust continues to flow in, so that there is a problem that the fine dust concentration of the accommodation space 19 is not lowered. The first air curtain device 200 and the second air curtain device 400 described below may be referred to as the air curtain device 200 and the auxiliary air curtain device 400, respectively.

First, an operation start step of starting operation by turning on the first air curtain device 200 and the ventilation device 300 is performed (S410). When the first air curtain device 200 and the ventilation device 300 are started, fine dust inflow is blocked from the outside and the fine dust inside is filtered.

In this case, the first air curtain device 200 and the ventilation device 300 are operated according to a preset operating step (S420). The first air curtain device 200 and the ventilation device 300 may discharge the air at a predetermined amount of air volume and wind speed according to a preset operation step. In addition, the first air curtain device 200 discharges air in the direction of gravity in a predetermined operating step.

Thereafter, the dust measurement step of measuring the fine dust concentration is performed on the internal fine dust sensor 40 (S431). When the internal fine dust concentration measurement value measured by the internal fine dust sensor 40, that is, the fine dust concentration measurement value of the accommodation space 19 is transmitted to the control unit 100, the control unit 100 measures the fine dust concentration measurement value and the reference value. Compare.

When the fine dust concentration measurement value is less than the reference value (S431-N), the control unit 100 controls the first air curtain device 200 and the ventilation device 300 to operate according to a predetermined operating step.

When the fine dust concentration measurement value exceeds the reference value (S431-Y), the control unit 100 controls the first air curtain device 200 and the ventilation device 300 to operate according to the elevated operating step (S432). Therefore, the wind speed increase step of increasing the wind speed of the air discharged from the first air curtain device 200 and the ventilation device 300 is performed. In this case, an airflow increasing step may be performed in which the airflow increases together.

Thereafter, when the first measurement time, which is the time measured from the operation point rising time, is less than the first reference time (S441-N), the controller 100 continuously measures the time. When the first measurement time is greater than or equal to the first reference time (S441-Y), the control unit 100 compares the fine dust concentration measurement value with the reference value (S442).

When the fine dust concentration measurement value is less than the reference value (S442-N), the control unit 100 controls the first air curtain device 200 and the ventilation device 300 to operate according to a predetermined operating step.

When the fine dust concentration measurement value exceeds the reference value (S442-Y), the controller 100 controls the wind direction of the first air curtain device 200 to be the first wind direction (S443). That is, the first wind direction adjusting step is performed. The first wind direction is a direction inclined downward in the direction from the doorway 17 toward the outside. This control method is a result of assuming that an air curtain interferes with a person or a bulky object under the entrance 17 or the first discharge unit 270.

Thereafter, when the second measurement time, which is the time measured from the first wind direction setting time point, is less than the second reference time (S451-N), the controller 100 continuously measures the time. When the second measurement time is greater than or equal to the second reference time (S451-Y), the control unit 100 compares the fine dust concentration measurement value and the reference value (S452). The second reference time is a reference time which is determined to correct the interference of the air curtain and is compared with the measurement time, and may be set shorter than the first reference time under the determination that the fine dust concentration will be lowered within a short time.

When the fine dust concentration measurement value is less than the reference value (S452-N), the control unit 100 controls the first air curtain device 200 and the ventilation device 300 to operate according to a predetermined operating step.

When the fine dust concentration measurement value exceeds the reference value (S452-Y), the controller 100 controls the wind direction of the first air curtain device 200 to be the second wind direction (S453). That is, the second wind direction setting step is performed.

In addition, the second air curtain device 400 is controlled to operate (S453). That is, the additional discharging step is performed.

The second wind direction is a direction inclined downward in the direction from the doorway 17 toward the inside.

On the other hand, the wind direction, which is the discharge direction in which the second air curtain device 400 discharges air, is the gravity direction. Accordingly, the wind direction of the first air curtain device 200 and the wind direction of the second air curtain device 400 form a predetermined angle to each other. In addition, there is a region where air does not flow between the flow of air discharged from the first air curtain device 200 and the flow of air discharged from the first air curtain device 200.

This control method is a result of assuming strong wind from outside. When strong wind blows toward the bus shelter 1, fine dust may flow into the bus shelter 1, and the concentration of the fine dust in the accommodation space 19 may increase. However, if there is an area where no air flows between the flow of air discharged from the first air curtain device 200 and the flow of air discharged from the first air curtain device 200, the fine dust may be prevented from entering. have.

Thereafter, when the third measurement time, which is the elapsed time measured from the second wind direction setting time point, is less than the third reference time (S461-N), the controller 100 continuously measures the time. When the third measurement time is greater than or equal to the third reference time (S461-Y), the controller 100 compares the fine dust concentration measurement value with the reference value (S462). The third reference time is a reference time which is determined to correct the interference of the air curtain after the second wind direction is set and compared with the measurement time, and may be set shorter than the second reference time under the determination that the fine dust concentration will be lowered within a short time. have.

When the fine dust concentration measurement value is less than the reference value (S462-N), the control unit 100 controls the first air curtain device 200 and the ventilation device 300 to operate according to a predetermined operating step.

When the fine dust concentration measurement value exceeds the reference value (S462-Y), the control unit 100 stops the operation by turning off the first air curtain device 200 and the ventilation device 300 (S470).

The wind speed control step, the air volume control step, the first wind direction control step, the second wind direction control step and the additional discharge step are all the wind speed of the air discharged from the first air curtain device 200 and the second air curtain device 400 And it may be referred to as a discharge control step of adjusting one or more of the wind direction.

Hereinafter, a control method of the bus shelter 1 will be described in detail with reference to FIG. 5. FIG. 5 shows a control method of the bus shelter 1 which lowers the fine dust concentration inside the bus shelter 1 while efficiently using power. Flowchart.

Referring to FIG. 5, first, a pattern setting step (S510) of setting a pattern of an external fine dust concentration according to the flow of time using an external fine dust concentration detected by the external fine dust sensor 30 is performed. The external fine dust concentration changes in a regular pattern throughout the day. In this pattern, if the amount of power used or the amount of power consumed by the first air curtain device 200 and the ventilation device 300 is adjusted, power can be efficiently used. Thereafter, the pattern tracking step S510 is performed by controlling the amount of power consumed by the first air curtain device 200 and the ventilation device 300 according to the pattern of the external fine dust concentration set in the pattern setting step.

Then, the bus information receiving step (S520) for receiving information on the bus using the second communication terminal 52 and the bus dust measurement step (S520) for measuring the external fine dust concentration is performed when the corresponding bus approaches. .

Subsequently, a bus specific step S530 of specifying a bus that excessively discharges soot is performed according to the fine dust concentration measured in the bus dust measurement step.

And the weather information receiving step (S540) for receiving the weather information by using the first communication terminal 51 is performed.

After the weather information receiving step S540 is performed, a step S551 is performed to determine whether or not the exhaust fumes bus is approaching. If the exhaust fumes bus is not approached (S551-N), a step of continuously determining whether or not the exhaust fumes bus is approached is performed. The controller 100 determines whether or not the exhaust fumes bus is accessed from the information received through the BIT. When the exhaust fumes bus is approaching (S551-Y), a pattern correction step (S570) for correcting the pattern set in the pattern setting step (S510) is performed.

On the other hand, after the weather information receiving unit (S540) system is performed, the step of determining whether the number of people is excessive (S552) may be performed along with the step (S551) of determining whether or not the excess exhaust bus. The number of persons means the number of persons accommodated in the accommodation space 19 by the personnel count sensors 21 and 23. If it is determined that the number of people is not excessive (S552-N), the step of continuously determining the number of people is performed. If it is determined that the number of people is excessive (S552-Y), the pattern correction step (S570) for modifying the pattern set in the pattern setting step (S510) is performed.

On the other hand, after the weather information receiving step (S540) is performed, the step of determining whether the external wind speed is high (S553) is a step of determining whether the number of people is excessive (S552) and the step of determining whether or not the access of the excess fumes bus ( S551) may be performed together with one or more of the above. The external wind speed is the outside wind speed of the bus shelter 1, and whether the outside wind speed is high is determined by the controller 100 through weather information received through the first communication terminal 51, in particular, local weather information.

If it is determined that the wind speed is not higher than the reference value (S553-N), a step of continuously determining whether the external wind speed is high is performed. If it is determined that the wind speed is higher than the reference value (S553-Y), the pattern correction step (S570) for correcting the pattern set in the pattern setting step is performed.

The pattern modification step S570 may include a first blower 210, a second blower 310, a third blower 410, a first plasma lamp 215, a second plasma lamp 350 and a heater ( Means to adjust the operation step of the 340. The operation stage here refers to the amount of power consumed.

For example, the pattern modification step S570 increases the amount of power consumed by the first blower 210, the second blower 310, and the third blower 410, and lowers the amount of power consumed by the heater 340. It can mean to make.

In this case, maintaining or increasing the amount of power consumed by the first plasma lamp 215 and the second plasma lamp 350 may be included in the pattern modification step S570. Filtering the air by increasing the strength of the air curtain to prevent fine dust inflow and increasing the air moving speed in the ventilation device 300 is more effective than operating the heater 340 for the convenience of the person in the accommodation space 19. Because it is important.

Accordingly, the discharge rate at which air is discharged from at least one of the first air curtain device 200, the second air curtain device 400, and the ventilation device 300 increases, and the set temperature of the heater 340 decreases. .

After performing the pattern modification step S570, it is determined whether the amount of power exceeds the allowable value (S581). When the amount of power exceeds the allowable value (S581-Y), the amount of power consumed by the heater 340, the first plasma lamp 215 and the second plasma lamp 350 is lowered (S582). If the amount of power does not exceed the allowable value (S581-N), the external fine dust concentration is further measured to further set the pattern of the external fine dust concentration (S583). The power consumption of the first air curtain device 200, the second air curtain device 400, and the ventilation device 300 is additionally set in accordance with the pattern of the external fine dust concentration, in operation S583.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
