5 is a block diagram illustrating a purifying system for purifying vehicles using IoT technology according to an embodiment of the present invention. 5, the purification system of the purification vehicle 1 includes a GPS satellite 15 that transmits a GPS signal to the navigation terminal 11, a first communication company server 16 that provides a navigation service, a purification vehicle 1, A navigation terminal 11 for receiving traffic information through a first communication company server 16 and receiving GPS signals through a GPS satellite 15 to provide a guidance service after receiving information about a destination from a user, A second communication company server 17 for transmitting a purifying information signal to the purifying information receiving terminal 12, which is information for determining the polluted area compartment, the rotation angle of the exhaust duct 300, the amount of the purifying material, A purification information reception terminal 12 mounted in the purification vehicle 1 for receiving purification information from the second communication company server 17 and a purification information reception terminal 12 installed in the outside of the purification vehicle 1 for measuring the air pollution degree outside the purification tank 1 The contamination detection sensor 13, the discharge device ( The pollution detection sensor 13 and the discharge device driving units 110 and 140 which drive the discharge device driving units 110 and 140 and the navigation terminal 11, the purification information receiving terminal 12, the contamination detection sensor 13, And a controller 10 for receiving signals from the navigation terminal 11, the purifying information receiving terminal 12 and the contamination detecting sensor 13 and controlling the discharging device driving units 110 and 140.

The navigation terminal 11 generally refers to an apparatus for fixing the interior of the vehicle to provide the current position information of the vehicle, but is not limited thereto and may be a mobile communication terminal. Here, the mobile communication terminal is a mobile communication terminal equipped with a GPS receiving function and a communication function, and refers to a device such as a mobile phone, a PDA (Personal Digital Assistant), a notebook, and a PMP (Portable Multimedia Player).

The purifying information receiving terminal 12 is not limited to a specific terminal as an apparatus capable of receiving information from the second communication company server 17, and does not exclude the purifying information receiving terminal 12 composed of a mobile communication terminal.

The pollution detection sensor 13 may be any sensor capable of detecting the pollution degree of the atmosphere, and the pollution degree of the air is mainly denoted as fine dust, volatile organic compounds, nitrogen compounds, sulfur oxides, ozone, do.

Here, fine particulate matter (PM) or dust is an air pollutant containing a large number of air pollutants together with sulfur dioxide, nitrogen oxides, lead, ozone, and carbon monoxide. It is a fine dust with a particle size of 10 μm or less that floats in the atmosphere over a long period of time. It is called PM10. When the particle is 2.5 μm or less, it is called PM2.5 and is called 'ultrafine dust' or 'ultrafine dust. Technically, it is called aerosol. Fine particles are also called suspended particles and particulate matter, and have slightly different meanings depending on their names. The aerodynamic diameter (diameter) of the particulate matter is about 10 to 100 μm. If the particle size is larger than this, the residence time in the atmosphere is very short due to the sedimentation effect due to gravity.

It is a very small substance that is invisible to the naked eye. It is a particulate material with a diameter of 10 μm or less that floats or falls down in the air. Fine dust is a substance that greatly affects the human body. London smog, which killed 20 people in 1948 in Donora, Pennsylvania, USA, and caused about 4,000 deaths in 1952, is a leading example of how fine dust affects the human body. Since then, various epidemiological studies have been carried out on the effect of fine dust on the human body. Especially, fine dust particles (PM10) of 10 μm or less are likely to have a detrimental effect on the human body, such as increasing disease incidence and mortality rate in vulnerable groups It turned out. Since the results of these studies, governments have begun to prepare air pollution measures, and air pollution standards have been set up to reduce the harmful effects of fine dust on human body and environment.

A state in which particulate matter (solid or liquid) floats in the air is generally called an aerosol. It is usually said to be dust. The particle size range of the dust is 0.001 ~ 1000 ㎛. However, since the dust larger than 70 ㎛ is precipitated immediately upon occurrence, the dust of 70 ㎛ or less is generally called total suspended particle (TSP). A dust particle size of 0.1 μm or less is called an ultra range, and most of the dust is distributed in a range of 0.1 to 10 μm. Particles in the range of 0.1 to 1 μm have a long residence time in the atmosphere and are most easily permeable to the alveoli because they are difficult to precipitate or flocculate due to the nature of the particle size distribution. Particles with a size of 0.5 μm have the largest scattering effect of light, which may cause a decrease in visibility.

PM10 (Particulate Matter Less than 10 μm) refers to dust particles whose size is 10 μm or less. It is based on an annual average of 50 ㎍ / ㎥ in environmental standards and 100 ㎍ / ㎥ in 24 hours a year. It infiltrates into the alveoli of the human body, directly causes various respiratory diseases, and exacerbates the immune function of the human body. The World Health Organization (WHO) guidelines set an average annual dose of 20 μg / ㎥ and an average of 50 μg / ㎥ for 24 hours, with an average annual dose of 70 μg / ㎥ in developing countries.

PM 2.5 (Particulate Matter Less than 2.5 μm) refers to dust particles with a size of 2.5 μm or less. This is called ultrafine dust. As a result of the fact that the particle size is smaller and the effect on health is great, it started to introduce the criteria for fine particles in the developed countries in the late 90s.

The Republic of Korea announced the annual average of 25 ㎍ / ㎥ and 50 ㎍ / ㎥ for 24 hours a year, which is scheduled to be enacted in January 2015. The US has set an annual average of 15 ㎍ / ㎥ and an average of 35 ㎍ / ㎥ for 24 hours. This is called ultrafine dust. The World Health Organization (WHO) guidelines set an annual average of 10 μg / ㎥ and an average of 24 μg / ㎥ for 24 hours.

Volatile Organic Compounds (VOCs) are hydrocarbon compounds that volatilize in the air and generate odor and ozone. They are carcinogens that cause damage to the nervous system through skin contact and inhalation. Benzene, formaldehyde, toluene, xylene, ethylene, styrene, and acetaldehyde.

These volatile organic compounds often cause bad odors even at low concentrations, and the compounds themselves are directly harmful to the environment and human body, or participate in photochemical reactions in the atmosphere and generate secondary pollutants such as photochemical oxides. Volatile organic compounds (VOCs) are mainly produced and stored in petrochemical refining coating plants, automobile exhaust gas, construction materials such as paints and adhesives, and storage tanks in gas stations.

A generic term for organic compounds in liquid or gaseous form that are easily vaporized into the atmosphere due to their high vapor pressure. This is contained in paints, solvents, and the like. When it coexists with nitrogen oxides in the atmosphere, it produces photochemical oxidative substances such as ozone and a fan by causing the photochemical reaction due to the action of sunlight, and refers to the substances that cause photochemical smog at this time. It is an air pollutant, a toxic chemical with carcinogenic properties, and it is also a precursor of photochemical oxides. It is also a cause of global warming and destruction of the stratosphere of the ozone layer. From the viewpoint of environmental protection, development of technology for low-volatile organic compounding is required. In response to this, high solidification of the coating material, hydration of the middle and top basecoat, clearance of the two-liquid curing type, and development and introduction of powder clearance have been carried out.

Nitrogen oxides (NOx) are compounds of nitrogen and oxygen, and nitrogen in the air is oxidized at high temperatures during the combustion process. Seven species are known. The most important pollution problem is nitrogen monoxide (NO) and nitrogen dioxide (NO2).

Nitrogen oxide is a compound of nitrogen and oxygen and is a collective term such as N₂O (nitrous oxide), NO (nitrogen monoxide), NO₂ (nitrogen dioxide), N₂O₃ (nitrogen trioxide), N₁O5 (nitrogen oxide). Nitrogen contained in fossil fuel such as nitrogen in air or automobile is oxidized in a high temperature atmosphere. Cough, and sputum. It reacts with the sun's ultraviolet ray, soot, etc., causing photochemical smog, or it is dissolved in the moisture in the air and becomes acetic acid, which causes acid rain.

Typical sources of nitrogen oxides include automobiles, airplanes, ships, industrial boilers, incinerators, and electric furnaces.

Nitrogen oxides are highly influenced by traffic volume and sunlight, and are acute toxic substances that cause lung diseases leading to death. Bronchial inflammation, asthma, and chronic bronchitis. Symptoms include cough, sputum, tears, and shortness of breath.

Nitrogen oxides are regulated as major air pollutants, not only causing acid rain, but also stimulating the eyes and respiratory tracts and ending plants. In addition, nitrogen oxides react with sunlight to generate ozone. When the concentration of ozone in the atmosphere increases, the respiratory and eye senses irritation and causes coughing.

Sulfur oxides (Sox) refers to sulfur oxides in which sulfur and oxygen are commonly combined, but in the case of pollution, sulfur dioxide, sulfur trioxide and sulfuric acid mist contained in the soot. It is the cause of air pollution and the largest source of sulfur dioxide and sulfur trioxide is contained in the exhaust gas generated by the combustion of heavy oil and other sulfuric acid production and metal refining.

Sulfur oxides, sulfur dioxide SO2, one of the air pollutants, and its related substances, including sulfur trioxide SO3 and sulfuric acid mist. Especially in the field of environment-related, it is often called antioxidant. It is usually designated SO2.

Ozone (O3) is ozone, ozone, which means 'smell' because of its peculiar odor. Ozone is an oxygen isotope, and its molecular formula is O3, which is very unstable compared to oxygen. Ozone is easily decomposed into oxygen and the resulting unstable oxygen atoms have the property of oxidizing other substances. It is used as a sterilizing bleach using the strong oxidizing power of oxygen atom. In the natural state, ozone is generated by lightning. Oxygen molecules are split into atoms by lightning, and these oxygen atoms combine with neighboring oxygen molecules to form ozone.

Carbon monoxide (CO) is a colorless, odorless gas that is produced by incomplete combustion when the fuel is burning in a state of oxygen deficiency. When you enter a person's lungs, it binds to hemoglobin in the blood, blocking oxygen supply and leading to death if severe.

Carbon monoxide is contained in the burning gas of briquettes and exhaust gas of automobiles, and when a large forest fire occurs, a large amount of carbon monoxide is generated due to lack of oxygen around the surroundings, and sometimes it is contained in tobacco smoke when it is cigarette.

The action of carbon monoxide in the human body is not toxic per se, but it binds to the hemoglobin (Hb) in the blood in the lungs to interfere with the ability of oxygen to supply oxygen into the body, which is the original function of Hb, As a result, symptoms of poisoning appear. When carbon monoxide is continuously inhaled and oxygen supply to the body becomes insufficient, the central nervous system (brain, vertebrae) sensitive to oxygen deficiency is first affected, and headache, dizziness, tinnitus, chest throbbing, pulse increase, vomiting, Finally, anesthesia can fall. At present, atmospheric carbon monoxide standards in Korea are less than 25ppm for 1 hour and less than 9ppm for 8 hours.

The pollution detection sensor 13 detects all the above-mentioned air pollutants, and among these, the volatile organic compounds, nitrogen compounds, sulfur oxides, ozone, carbon monoxide, and the like other than fine dusts can be detected. Of course, fine dust can also be detected.

The first and second communication company servers 16 and 17 refer to all devices that provide wireless Internet services, but the present invention is not limited to this, and a mobile communication service provider may establish a system such as a base station and a central communication sensor, A device providing a network such as a Personal Communications System (PCS), a Code Division Multiple Access (CDMA), a Universal Mobile Telecommunications System (UMTS), a Digital Cellular Network (DCN) . Accordingly, the navigation terminal 11 is connected to the wireless Internet network provided by the first communication company server 16 to transmit various driving information of the purifier 1 to the outside of the vehicle including the inside information of the purifier 1 Can be transmitted. The purifying information receiving terminal 12 is also connected to the wireless Internet network provided by the second communication company server 17 so as to transmit the pollution degree information detected by the purifying vehicle 1 to the outside of the purifying vehicle 1 .

The second communication company server 17 may transmit information on the fine dust, but it is not limited thereto, and it is possible to transmit all the information on the above-mentioned air pollution material.

The control unit 10 stores map information of the contaminated area received from the navigation terminal 11 and first information received from the purifier information receiving terminal 12 and second information obtained from the contamination detecting sensor 13 The grid is set on the contaminated area and the priority between the unit grids UG is set on the basis of the grid, and then the movement route between the intersection points and the intersection areas is obtained through the navigation terminal 11. [ Then, when the purifier 1 moves, the rotation angle of the exhaust duct 300, the amount of the purified material discharged, and the composition ratio are set.

Hereinafter, a purification method of the purification vehicle 1 according to an embodiment of the present invention will be described with reference to FIG. 6 is a flowchart illustrating a method of purifying the purification vehicle 1 using the IoT technique according to an embodiment of the present invention.

According to the purifying method of the purifying vehicle 1, the purifying vehicle 1 moves inside the polluted area and discharges the purifying material to purify pollutants in the polluted area.

To this end, the purification method of the purification vehicle 1 includes a grid setting step S110 for setting a grid on the contaminated area so that the contaminated area is partitioned, a rank setting step S110 for setting the purification rank among the unit grid corresponding areas corresponding to the unit grid UG, A setting step S130, a moving route setting step S150 in which a moving route for guiding the movement of the vehicle is set in the contaminated area by receiving the information about the direction of the contaminated area from the outside, and the moving route setting step And a purge step (S170) for discharging and purifying the purifying material from the discharging device while sequentially moving the unit-grid corresponding area of the discharging device.

In the grid setting step (S110), the number of each unit grid (UG) forming the grid is determined according to the number of the polluted areas. If the number of polluted areas is large, the number of unit grid (UG) is increased. If the number of polluted area is small, the number of unit grid (UG) is also decreased.

Using the fact that the population is generally proportional to the size of the area, the grid is set so that a number of square shaped unit grids (UG) each having a length of 1 km and a length of 1 km are formed, do. In other words, as shown in FIG. 8, each of the boundary lines BD dividing the unit grid UG is set to 1 km.

The area of the unit grid UG may be set by the population density of the contaminated area. However, this is only an example, and the size of the unit grid (UG) can be variously set.

The following step S130 will be described in detail with reference to FIGS. 7 and 8. FIG. FIG. 7 is a diagram illustrating a method of setting a rank between unit grids UG shown in FIG. 6, and FIG. 8 illustrates a method of setting a rank between unit grids UG shown in FIG. .

The rank setting step S130 is a step of determining a rank to be cleaned between the unit grid corresponding regions constituting the grid. The ranking setting step S130 is performed based on the first information acquired from the outside of the purification vehicle 1 and the second information acquired by the detection of the contamination detection sensor provided in the purification vehicle 1. [

The first information includes at least one of air pollution degree, population density and traffic volume in the unit grid corresponding area. In the following description, the first information includes, for example, population density and traffic volume. Such first information may be referred to as purifying information as information used by the purifying vehicle 1 to purify the contaminated area. The first information including at least one of air pollution degree, population density and traffic volume, that is, the cleansing information is information received from the second communication company server 17 by the cleansing information receiving terminal 12. [

On the other hand, the second information includes the air pollution degree of the unit grid corresponding area detected by the pollution detection sensor 13. The second information is information on the air pollution degree that the pollution detection sensor 13 provided in the purification vehicle 1 senses and acquires.

Hereinafter, a method for determining the ranking between the unit grid corresponding regions by the first information including the population density and the traffic volume and the second information will be described.

The ranking among the unit grid corresponding areas is determined by the sum of weights of air pollution, population density and traffic volume. Here, the maximum weights of population density and traffic are the same, and the maximum weight of air pollution is equal to the sum of the maximum weights of the population density and traffic volume.

Referring to Tables 1 to 3, the air pollution degree, the population density, and the traffic volume are set to a level of 5 for each level, and a conversion score, that is, a weight value, is assigned to each level. The population density and the traffic volume are respectively set to the maximum conversion score, that is, the maximum weight is equal to 25, and the real-time pollution degree, that is, the air pollution degree, is set to the maximum conversion score,

7, the conversion score is 80 in the unit grid corresponding area of the first order, which is the highest priority. For example, a real-time contamination level of 100 ug / m3 or more is Level 5 (50 points), a traffic volume is 33 km / h, a level 3 (15 points), and a population density The population density is 1009, which is Level 3 (15 points).

On the other hand, the second rank, the unit grid corresponding area, has a score of 60. For example, the real-time contamination level is 60 ug / m3 and the level 3 (30 points), the traffic volume is 33 km / h, the level 3 (15 points), and the population density is the population The density is 1009 and Level 3 (15 points).

If a plurality of regions of the same rank are set, the ranking among them may be set as follows.

When a plurality of first ranked regions are set, the first ranked region closest to the region where the purification vehicle 1 is first located is set as the highest priority region, and the region closest to the highest ranked region is set as the next ranked region .

If a plurality of second ranked regions are separately set, the second ranked region closest to the first ranked region is set as the highest ranked region among the second ranked regions, and the region closest to the highest ranked region is set as the next ranked Lt; / RTI >

Meanwhile, as shown in FIG. 8, the rank setting step S130 may include a ranking initial setting step S211 for initially setting the rank of the cleansing between unit grid corresponding areas, and a ranking initial setting step S211 for clearing one or more unit grid corresponding areas , And an order resetting step S241 for resetting the purification order among the uncleaned unit grid corresponding areas.

The reason why the ranking setting step S130 is divided into the ranking initial setting step S211 and the ranking resetting step S241 is to cope with a situation in which the pollutant distribution inside the contaminated area changes during purifying by the purifying vehicle 1 to be.

The ranking initial setting step S211 is a step of setting a purifying rank among the unit grid corresponding areas before the polluted area is purified by the purifying vehicle 1 and includes the first information received from the outside of the purifying vehicle 1, Based on the second information acquired from the contamination detection sensor 13 provided in the first apparatus 1. The first information includes the air pollution degree, the population density and the traffic amount of each unit grid corresponding area, and the second information includes the air pollution degree of each unit grid corresponding area.

The air pollution degree in the ranking initial setting step S211 is the air pollution degree acquired through the second information. Therefore, in the initial ranking step S211, the purification vehicle 1 passes through all of the unit grid corresponding areas and measures the air pollution degree of each unit grid corresponding area through the pollution detection sensor 13. [

After the ranking initial setting step S211, a movement path initial setting step S212 is first performed in which a movement path for guiding the movement of the purification vehicle 1 within the contaminated area is first set. In the flowchart shown in FIG. 8, an n value indicating the order of the order re-ordering and the route re-setting is set to 1 (S213).

Thereafter, the purification vehicle 1 moves along the movement route along the grid-corresponding area of the first stage. However, since the air pollution degree may change while the purification vehicle 1 arrives at the first unit grid corresponding area, information on the air pollution degree, which is the second information through the pollution detection sensor 13, (S221).

Then, the purifying material is discharged through the discharging device in the unit grid corresponding area that has arrived (S222).

When the purge material discharge is completed in the corresponding unit grid corresponding area, the rank of the unit grid UG is reset (S241) and the travel path is also reset (S242 )do.

In this case, the ranking and the movement route between the unit grids UG are reset by using the first information and the second information obtained immediately before the purge, after the arrival (S241, S242). Here, the first information includes the entire air pollution degree of each unit grid corresponding area, and the second information includes the air pollution degree detected by the pollution detection sensor 13 at the time of information acquisition.

Meanwhile, the order of the unit grid UG and the resetting of the movement path are performed based on the first information and the second information, and the reliability determination of the first information is performed (S230).

If the reliability of the first information is lower than the allowable value (S230-N), the ranking and the movement path between the unit grids UG are not reset. Here, the reliability depends on the result of comparing the air pollution degree of the first information received before the purification vehicle 1 arrives before the purification vehicle 1 and the air pollution degree measured by the pollution detection sensor 13.

The degree to which the first information of the point at which the purification vehicle 1 is currently located deviates from the second information of the point where the first information is currently located is set to a predetermined value The population density and the traffic volume of the first information received before purification after arrival of the purification vehicle 1 as described above is determined to be high in reliability of the unit grid UG ) And resetting the movement route. Herein, the first information includes information on a unit-grid corresponding area to be moved later, as described above.

Thereafter, the value of n indicating the order of resetting and resetting the route is incremented by 1 (S243).

The ranking and the resetting of the movement route between the unit grids UG are continued until the unit grid corresponding area to be moved forward is narrowed to two points (S250). If the unit grid corresponding area to which the purification vehicle 1 moves is one point, the ranking and the movement path between the unit grids UG are not reset. The purification vehicle 1 moves along the predetermined movement path to acquire the contamination information, and then discharges the purification material through the discharge device and finishes the purification.

That is, as shown in FIG. 8, if the value of n increased after the resetting of the route and the resetting of the route is equal to or greater than the total number of the unit grids, the resetting operation S241 and the moving route resetting operation S243 are not performed any more.

9 to 10, a description will be made of a movement path setting step in which a moving path for guiding the movement of the vehicle is set in the contaminated area by receiving the information about the direction of the polluted area from the outside. Fig. 9 is a flowchart showing a method of setting the movement path of the purification vehicle 1 in the contaminated area shown in Fig. 6, and Figs. 10 and 11 are flowcharts showing the procedure of setting the movement path of the purification vehicle 1 in the contaminated area shown in Fig. And a method of setting a movement route is displayed on a map.

9 to 11, the movement path setting step S150 includes a first movement path setting step S330 in which a first movement path for guiding the movement of the vehicle is set within the unit grid corresponding area, And a second movement route setting step (S350) in which a second movement route for guiding the vehicle movement is established by interconnecting the first movement routes of the corresponding areas.

In the first movement path setting step (S330), a virtual wind direction line Z passing through the center of the unit grid UG is set in accordance with the average wind direction of the contaminated area (S331). The first movement route is set so that the purification vehicle 1 passes through the yaw line Z at least once.

Specifically, in the first movement path setting step (S330), a predetermined intersection area including the intersection point where the intersection line of the unit grid UG and the predetermined intersection line intersect and the intersection point is set after the virtual wind direction line Z is set (S333).

Thereafter, the first movement route is set so that the purification vehicle 1 passes the crossing region at least twice (S335).

In other words, in the first movement path setting step S330, a plurality of intersecting lines perpendicular to the average direction of the contaminated area and intersecting the unit grid UG boundary line are sequentially arranged so as to be spaced apart from each other by a predetermined distance along the average direction , A crossing area including an intersection of a unit grid (UG) boundary line and an intersection line is set, and a first movement path is set so that the purification vehicle 1 passes the intersection area at least twice. At this time, a plurality of intersecting lines are separated by a predetermined distance.

Accordingly, in the first movement path setting step S330, the unit grid corresponding area can be divided into the first and second partition areas by the virtual wind direction Z, and the purification vehicle 1 can be divided into the first The first movement path may be set so as to make the partition area and the second partition area at least once to reciprocate.

An example of setting the first movement route is shown in Fig. The average wind direction of the contaminated area is indicated by two arrows, and the wind direction line (Z) passes through the center of the unit grid (UG) and is set to be parallel to the average wind direction. The unit grid (UG) region is divided into two regions by a wind direction line (Z), that is, a first partition region and a second partition region.

The crossing lines A to F are perpendicular to the direction line Z and arranged at regular intervals along the average direction. The first crossing line A passes through the first intersection X0 at which the direction line Z first meets the unit grid UG boundary line.

The second intersection X1, Y1 between the second intersection line B and the boundary of the unit grid UG is formed at two points. Similarly, the third intersection points X2 and Y2 between the third intersection line C and the unit grid UG boundary line, the fourth intersection points X3 and Y3 between the fourth intersection line D and the unit grid UG boundary line, The fifth intersection points X4 and Y4 between the fifth intersection line E and the unit grid UG boundary line and the sixth intersection points X5 and Y5 between the sixth intersection line F and the unit grid UG boundary line, Are formed at two points, respectively. In this case, a crossing area (not shown) surrounding each intersection can be set. The crossing area is set such that the boundary line of the area is spaced a certain distance from the intersection.

At this time, in FIG. 10, the first movement path (dotted line) is shown passing through the specific intersection X1 to X5 or the intersection area so as to be zigzag, but it is not limited thereto and may be set in various forms as described above. In other words, the first movement route is set so that the purification vehicle 1 moves in a direction substantially perpendicular to the average direction. By the setting of the first movement path, the purifying material spreads in the entire area evenly in the contaminated area, thereby increasing the purification efficiency.

Another example of setting the first movement route is shown in Fig. Another example shown in Fig. 11 is the same as the example shown in Fig. 10 except that there are five intersecting lines and that the yaw line Z is perpendicular to the grid boundary of the stage.

On the other hand, in the second movement path setting step (S350), the second movement path is set as follows.

First, when the cleaned unit grid corresponding area and the cleaned unit grid corresponding area after the cleaning are mutually brought into contact with each other, the second moving path is set to the cleaned unit grid corresponding area. The purifying vehicle 1 is moved to the area corresponding to the next rank unit grid and then enters the unit grid corresponding area where the purifying process is completed again Thereby preventing the contaminated area from being contaminated again.

On the other hand, if at least one unit grid corresponding area is located between the unit grid corresponding area where the purification is completed and the corresponding rank order unit grid corresponding area after the unit grid corresponding area where the purification is completed, Corresponding unit grid corresponding area and the above-mentioned rank order unit grid corresponding area. Pollution of the unit grid corresponding area where the purification has been completed and pollution of the purification vehicle 1 due to entry into the area corresponding to the unit rank grid.

12, the rotation angle of the exhaust duct 300 of the purifier 1 moving along the movement path set in the unit grid corresponding area, the rotation angle of the purge material discharged from the exhaust duct 300, Set up to purify pollutants will explain the purification step.

In the purifying step, the rotation angle of the exhaust duct 300 of the purification vehicle 1, the emission amount and composition ratio of the purification material discharged from the exhaust duct 300, And second information including information on the second pollutant to be obtained by the detection of the contamination detection sensor 13. [

Here, the first pollutant includes atmospheric fine dust. Wherein the first pollutant refers to fine dust corresponding to at least one of PM 2.5 and PM 10.

The second pollutant includes atmospheric pollutants other than fine dust of the atmosphere. Here, the second pollutant refers to at least one of volatile organic compounds (VOCs), nitrogen oxides (NOx), sulfur oxides (SOx), ozone (O3), and carbon monoxide (CO).

The rotation angle of the exhaust duct 300 includes a vertical rotation angle (see FIG. 2) in which the exhaust duct 300 is set to move in the vertical direction within a predetermined range, The composition ratio of the angle and the purifying material is set by the composition ratio of the first contaminant mass and the second contaminant mass. Here, the upward and downward rotation of the exhaust duct 300 means that the second exhaust duct 310 rotates up and down with respect to the first exhaust duct 330.

The vertical rotation angle of the exhaust duct 300 and the composition ratio of the purifying material depend on the contamination pattern judged from the constituent ratio of the first pollutant mass and the second pollutant mass.

If the first contaminant mass is larger than the second contaminant mass, it is determined that the contaminated area is more contaminated than the atmosphere. In the reverse case, the contaminated area is judged to be more contaminated than the floor, 2 If the pollutant mass is the same, it is judged that the contamination level of the polluted area is almost the same at the air and the ground.

Therefore, if the bottom is judged to be more contaminated than the atmosphere, the exhaust duct 300 inclines downwardly, and the purifying material to be discharged is set so that the liquid volume fraction occupied by the liquid is larger than the gas volume fraction occupied by the gas.

If it is determined that the atmosphere is more contaminated than the floor, the discharge duct 300 is inclined upwardly and the purge material to be discharged is set such that the gas volume ratio is larger than the liquid volume ratio.

If it is determined that the atmosphere and the floor are contaminated to the same degree, the discharge duct 300 is horizontally disposed on the ground, and the discharged purge material is set so that the gas volume ratio and the liquid volume ratio are the same. Here, the gas of the purifying material is plasma, and the liquid is water sprayed from the nozzle portion 380.

On the other hand, while the purifier 1 is moving, the exhaust duct 300 is controlled to be arranged in parallel to the average direction. In other words, the exhaust duct 300 is controlled such that the direction in which the purge material is discharged from the discharge duct 300 during the movement of the purifier 1 is equal to the average direction of the contaminated area. At this time, the discharge duct 300 rotates horizontally and horizontally on the ground. At this time, the maximum range of the horizontal rotation angle of the discharge duct 300 (see FIG. 4) is set in advance.

For example, when the angular difference and the angular direction between the average wind direction and the movement path of the contaminated area are calculated, the exhaust duct 300 may be arranged in the direction of the corresponding direction . The angular difference and the angular direction are calculated at predetermined time intervals.

This is because the purifying efficiency is reduced if the purifying material is discharged in a direction not equal to the average direction, such as discharging in the opposite direction to the average direction. However, when the purification vehicle 1 is adjacent to the boundary of the unit grid UG, it is not equal to the average direction of the unit grid UG, and the discharge duct 300 is rotated to the side of the edge of the grid to discharge the purification material, .

The amount of the purge material is set for each unit grid corresponding area so as to correspond to the contamination level of the unit grid corresponding area acquired from the contamination detection sensor 13. [ The purge material is discharged by increasing the amount of rotation of the blowing fan 160 or increasing the amount of plasma generated in the plasma generator 900.
