Description

System that provides pollution information to vehicles through TPEG standard technology{SYSTEM FOR PROVIDING POLLUTION INFORMATION TO VEHICLES THROUGH TRANSPORT PROTOCOL EXPERT GROUP STANDARD TECHNOLOGY}

The present invention relates to a system for providing pollution information to a vehicle through a Transport Protocol Expert Group (TPEG) standard technology, and more specifically, pollution degree information for atmospheric environment and odor measured by a plurality of Internet of Things (IoT) sensors. Is provided to each vehicle through TPEG technology, which is an international standard for transmitting traffic travel information by classifying each region, and generates a pollution distribution map of the region where the vehicle is located from the pollution degree information on the air environment and odor in the vehicle. It relates to a system for providing pollution information to a vehicle through a TPEG standard technology that prevents external air from entering the vehicle while performing an alarm when the vehicle enters a contaminated area by checking the degree of contamination in a direction to pass.

In general, as the industry develops and the use of automobiles increases, the air pollution gradually increases, thereby seriously affecting human activities as well as life of animals and plants.

For example, due to the effects of global warming, the ozone layer is gradually destroyed and the amount of ultraviolet rays reaching the ground is gradually increasing, and the ultraviolet rays are harmful to use and health. In addition, since microparticles and ultrafine particles have very small particles, they penetrate into the body directly through the respiratory tract and degrade immunity and cause various diseases.

In particular, as the quality of life and interest in health have increased in recent years, IoT-based environmental management that induces healthy living patterns by monitoring air pollution information that threatens human health in real time, such as UV index and fine dust concentration around users The need for system development is being emphasized.

However, the current system that receives the air pollution level information is mostly provided by a user, such as a smart phone or tablet, through an application installed by a related agency such as the Agency, or through a media such as a broadcast or newspaper. It is common. In addition, in the case of vehicle drivers, it was mostly to check the air pollution level information of each region displayed through a billboard installed around the road.

As described above, there are many restrictions in order for users to receive information on the air pollution level of the area in which the user is located. In other words, most of the existing air pollution level information was provided with air pollution level information in a wide area unit such as city, county, district, etc., so air pollution level information was not provided for each limited area of tens to hundreds of meters in which users or vehicles are located. will be.

In addition, in the related art, in order to receive air pollution level information, it is inconvenient to use since a separate hardware device for wired/wireless communication must be provided in a smartphone or a vehicle owned by the driver.

Meanwhile, in recent years, a TPEG technology that shows real-time traffic information and travel information to a car navigation terminal using a DMB (Digital Multimedia Broadcasting) broadcast frequency has been used. In addition, weather or air environment information is additionally provided in addition to the real-time traffic information and travel information.

For example, if the DMB broadcasting station transmits weather or air environment information for each region to a broadcasting frequency, the navigation terminal provided in the vehicle receives and displays weather or air environment information of a region in operation, so that the driver can obtain weather or environment for a specific region. You can check the information in real time.

However, since the conventional weather or air environment information providing service as described above provides weather or air environment information in a relatively wide area, even if a time difference of several seconds occurs due to the characteristics of a vehicle moving at a high speed, the current position of the vehicle Frequently, it was not possible to use accurate air pollution level information for the information.

In other words, the air pollution degree information is not provided by reflecting the speed or movement direction of the vehicle, so even if the air pollution degree information is provided through the TPEG technology, the air pollution degree of the location where the vehicle is currently located, even if the vehicle is rapidly moving from that point This results in receiving air pollution level information for the point that has already passed, not information, and accordingly, the current location of the vehicle and the air pollution level information do not match, and the reliability of the pollution level information providing service is caused by the use of incorrect air pollution level information. There was a problem that was greatly reduced.

In addition, in the past, only information on the atmospheric environment was provided, and information on the odor around the road was not provided. Therefore, if there is barn around the road or odor occurs due to compost, external air is blocked from vehicles passing through the contaminated area. Was not properly performed, and this caused a problem that the driver had to take the odor until the window was closed or the operation to switch to the internal circulation mode was performed.

Therefore, in the present invention, the pollution level information of each region for the air environment and the odor generated by collecting from a plurality of IoT sensors is provided to each vehicle using TPEG technology, and the vehicle can be used from the pollution degree information for the air environment and odor in the vehicle. After creating the distribution map of the passing area, we intend to propose a method to automatically block the inflow of external air while performing an alarm when entering a contaminated area above the standard by checking the contamination level in the direction to pass the vehicle.

When an abnormality occurs, an alarm is displayed and a system for sharing information with other mobile terminals through an open IoT platform-based server is described.

It is a conceptual diagram to explain the process provided.

1 and 2, the system of the present invention is a pollution information providing server 100, a plurality of IoT sensors 200, DMB broadcasting server 300, database 400, vehicle terminal 500, etc. It consists of.

The pollution level information providing server 100 is connected to each of the plurality of IoT sensors 200 through a network by wired or wireless communication, and fine dust, ultrafine dust, yellow dust, ozone, and the like measured by the plurality of IoT sensors 200. After receiving the pollution level information on the atmospheric environment such as nitrogen dioxide, carbon monoxide, and sulfur dioxide, and the pollution level information on the smell related to the odor, the location information of each of the IoT sensors 200 receives the received pollution level information on the atmospheric environment and the smell Pollution degree information classified for each region is generated by referring to (ie GPS information).

In addition, the pollution degree information providing server 100 transmits the pollution degree information generated for each region to the DMB broadcasting server 300 through a network, and the DMB broadcasting server 300 transmits the pollution degree information for each region through TPEG technology. It is to be provided to the vehicle terminal 500 passing through each region, and based on the pollution degree information transmitted from the vehicle terminal 500 through TPEG technology, generates a pollution distribution map of the region where the vehicle is located, and then refers to the pollution distribution map. By confirming the degree of contamination in the direction of passing through the vehicle, if the vehicle moves through the contaminated area as a result of the check, it alerts the driver and automatically blocks the inflow of vehicle from outside air. Here, the pollution degree displayed through each region's pollution distribution map may be variously displayed in a form including numeric digital data, linear curved analog data, or a combination thereof.

That is, the pollution degree information providing server 100 generates pollution degree information for each region based on the pollution degree information of the atmospheric environment and the odor measured by the plurality of IoT sensors 200 and the location information of the plurality of IoT sensors 200, and By providing to each vehicle passing through the area using TPEG technology through the DMB broadcasting server 300, the vehicle measures pollution information and pollution information about the air environment and odor included in the pollution information in the vehicle The location information of each IoT sensor is overlapped with pre-stored road information to generate a pollution distribution map, and then, from the pollution distribution map, the pollution degree in a direction to pass a vehicle is checked, and when the vehicle moves to a contamination area, It is to provide an alarm through visual, auditory, or a combination of these that the degree of contamination is higher than the preset reference data, and to automatically block external air from entering the vehicle.

This is one of the main features of the present invention, the current location and the degree of contamination of the vehicle, which is a conventional problem caused by the provision of pollution information for the late air environment and odor due to the fact that the vehicle does not take into account the fast moving situation or the direction of travel. Inconsistencies and inaccuracies can be resolved, and vehicle drivers or passengers traveling through a contaminated area are prevented from being exposed to contaminated air based on the provision of accurate pollution degree information and vehicle ventilation control, so that the vehicle can be operated in a comfortable environment. .

In this case, when the pollution degree information providing server 100 provides pollution information for each region to each vehicle passing through the region using the TPEG technology through the DMB broadcasting server 300, the data amount of the pollution degree information for each region is large. Therefore, it should be possible to perform large-scale transmission while suppressing the increase in traffic.

To this end, when the pollution degree information providing server 100 generates the pollution degree information for each region and provides it to the DMB broadcasting server 300, it distributes data within a certain period and transmits the same IoT sensor. By introducing a method of changing the pollution level information for each unit time or transmitting only the difference value of the pollution information for each unit time, it is possible to transmit a large amount of data while reducing traffic generation through temporal data compression and coding. In addition, in addition to the above method, a method of transmitting only when the pollution degree information for each unit time is greater than or equal to a reference value judged to be contamination or when the pollution degree information is significantly changed beyond a preset range may be introduced.

On the other hand, unlike the above description, the pollution level information providing server 100 may directly generate a pollution distribution map for each region and introduce and use a method of providing it to each vehicle terminal 500 through the DMB broadcasting server 300.

That is, the pollution degree information providing server 100 generates pollution degree information for each region based on the pollution degree information on the atmospheric environment and the odor collected from the plurality of IoT sensors 200 and the location information of each IoT sensor 200, and then Pollution degree information by region overlaps with previously stored road information to generate a pollution distribution map for each region, and each vehicle terminal operating a corresponding region by applying TPEG technology through the DMB broadcast server 300 to the generated pollution map for each region It is to be provided as (500), and the vehicle terminal 500 receives it and checks the degree of pollution in the expected direction of passing the vehicle from the pollution distribution map by region extracted with TPEG data to block the occurrence of an alarm in the polluted area and block external air inflow. .

At this time, when the pollution degree information providing server 100 provides the pollution distribution map for each region to each vehicle passing through the corresponding region using the TPEG technology through the DMB broadcasting server 300, it is performed when providing the pollution degree information for each region As in the previous method, compression and coding should be performed to suppress the increase in traffic and to perform large-scale transmission. Here, the pollution distribution map for each region is a map information, unlike the pollution information described above, so the amount of data is much larger, but if the entire map information is temporally and spatially compressed and coded, the amount of data can be greatly reduced. The compression and coding method is the same as the above description, so a detailed description thereof will be omitted.

In addition, the pollution level information providing server 100 continuously stores information including location information, type, measurement period, failure occurrence, operation program update information, or a combination of each of the plurality of IoT sensors 200 in the database 400. By storing and managing the data, it is possible to assist in smoothly checking or maintaining a failure.

The IoT sensors 200 are installed at regular intervals around the road, and are connected to the pollution level information providing server 100 via wired or wireless communication through a network, and the pollution level of the atmosphere and odor of the installation area is determined. After measuring according to a predetermined period or measuring at the request of the pollution degree information providing server 100, the pollution degree information on the measured air environment and odor is transmitted to the pollution degree information providing server 100.

In addition, the IoT sensor 200 includes at least one sensor capable of measuring odors, as well as atmospheric environments such as fine dust, ultrafine dust, yellow dust, ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide, and the pollution degree inside A communication module performing communication with the information providing server 100 and a memory in which an operation program is stored are provided.

At this time, the IoT sensor 200 is preferably installed in a place close to the ground in order to increase the accuracy of the measurement of the atmospheric environment and odor, and can be installed in various places such as buildings and houses in addition to the road.

The DMB broadcasting server 300 converts the pollution degree information for each region provided from the pollution degree information providing server 100 into TPEG data, and transmits it to a vehicle terminal 500 located in each region by carrying it on a broadcast signal.

At this time, the DMB broadcasting server 300 is capable of converting the entire pollution information for each region into TPEG data and transmitting it on a broadcast signal. However, since the data transmitted through TPEG is large, the city, metropolitan cities, and provinces to reduce the amount of data. It is desirable to divide the pollution information for each region into TPEG data by dividing it by unit of each region or city and district, and then transmit it on a broadcasting signal broadcast in the region. In other words, the broadcasting signal transmitted by each region is loaded with information on the distribution of pollution related to the region.

Meanwhile, when the pollution distribution map for each region in the form is provided from the pollution information providing server 100, the DMB broadcasting server 300 converts the pollution distribution map for each region into TPEG data, and places it in a broadcast signal to be located in each region. It can be sent to the vehicle terminal 500.

The database 400 includes management information of the plurality of IoT sensors 200, pollution degree information or pollution distribution for each region generated by the pollution degree information providing server 100, and various kinds of operations required for the operation of the pollution degree information providing server 100 Save and manage motion programs.

The vehicle terminal 500 is a typical navigation terminal used in a general vehicle, receives the DMB broadcast signal transmitted through the network from the DMB broadcast server 300, and includes it in the TPEG data extracted from the received DMB broadcast signal Pollution level information for each region is checked by overlapping the location information of each IoT sensor measuring the pollution level information and the pollution level information for the air environment and odor included in the identified pollution level information for each region. Create a distribution chart.

In addition, the vehicle terminal 500 confirms a predicted direction of passing of the vehicle through sensing information such as speed, acceleration, and steering angle measured by various sensors provided in the vehicle, and then checks the degree of contamination in the predicted direction of passing the vehicle in the pollution distribution map of each region. Then, the checked pollution level is compared with a predetermined threshold value to determine whether the vehicle enters a contaminated area above a predetermined standard, and as a result of the determination, when the vehicle enters the contaminated area, an external circulation mode is performed while an alarm such as sound or indication is performed. Switch to the internal circulation mode to prevent external air from entering the vehicle.

In addition, the vehicle terminal 500 is a vehicle identified through various sensors installed in the vehicle when the information included in the TPEG data extracted from the DMB broadcast signal received through the network is a map-type pollution distribution map rather than the regional pollution information described above. Check the degree of contamination in the direction of passage from the pollution distribution map, and compare the checked pollution level with a predetermined threshold value to determine whether the vehicle enters the contaminated area, and as a result of the determination, when the vehicle enters the contaminated area, perform an alarm and external It is possible to perform control to block the inflow of air to the vehicle.

Meanwhile, the pollution degree information providing server 100 and the DMB broadcasting server 300 may be integrated and used as one when operated by the same operator or when a technical partnership is established.

In addition, the present invention provides accurate and rapid air environment and odor pollution information in the area in which the vehicle moves through the use of the vehicle terminal 500, which is a navigation device that has been used previously, without the need to add a separate hardware device to each vehicle. Will be provided.

The process of providing pollution information to the vehicle through the TPEG standard technology will be described in detail with reference to FIG. 2 as follows.

First, the pollution degree to the atmospheric environment, such as fine dust, ultrafine dust, yellow dust, ozone, nitrogen dioxide, carbon monoxide, sulfur dioxide, etc. in each of the plurality of IoT sensors 200 installed at regular intervals around the road may be measured. Measures, and transmits the measured pollution level information about the air environment and odor to the pollution level information providing server 100 through the network (①).

Then, the pollution degree information providing server 100 collects pollution degree information on the atmospheric environment and odor performed by the plurality of IoT sensors 200, and measures the pollution degree information on the atmospheric environment and odor and the plurality of IoTs measuring the pollution degree information. Pollution degree information for each region is generated by referring to each location information of the sensor 200 (②).

In addition, the pollution degree information providing server 100 transmits the pollution degree distribution for each region to the DMB broadcasting server 300, TPEG the pollution degree information for each region received from the pollution degree information providing server 100 in the DMB broadcasting server 300 After being converted into data, the converted TPEG data is carried on a broadcast signal and transmitted to the vehicle terminal 500 located in each region (③).

On the other hand, the vehicle terminal 500 receives the DMB broadcast signal transmitted from the DMB broadcast server 300, extracts TPEG data from the DMB broadcast signal, checks the pollution level information for each region, and is included in the pollution level information for each region. Pollution distribution map of the area by overlapping the pollution information of the atmospheric environment and the odor measured by the plurality of IoT sensors 200 and the location information of each of the plurality of IoT sensors 200 and the previously stored road information. Creates (④).

In addition, the vehicle terminal 500 checks the sensing direction of the speed, acceleration, steering angle, etc. measured by various sensors provided in the vehicle to check the predicted direction of passing the vehicle, and determines the predicted direction of passing the vehicle in the regional pollution distribution map. Check the degree of contamination and display it on the screen (⑤).

In addition, the vehicle terminal 500 determines whether the vehicle enters a contaminated area that is above a standard because the degree of contamination in the direction in which the identified vehicle is expected to pass exceeds a preset threshold, and sounds, indications, etc. when the vehicle enters the contaminated area The external circulation mode is switched to the internal circulation mode while the alarm is executed to control external air from entering the vehicle (⑥).

Meanwhile, when the TPEG data extracted from the DMB broadcast signal received through the network directly receives the pollution distribution map in the form of map, not the regional pollution information, the vehicle terminal 500 checks the pollution degree in the expected direction of the vehicle from the pollution distribution map. And, it is confirmed whether the passage through the polluted area through comparison with the identified pollution level and a preset threshold, and if it is determined that the passage passes through the polluted area, the vehicle ventilation control may be performed while performing an alarm.

FIG. 3 is a diagram showing the configuration of the pollution degree information providing server 100 of FIG. 1 in more detail.

As illustrated in FIG. 3, the pollution degree information providing server 100 includes a communication interface unit 110, an information collection unit 120, an information generation unit 130, an information providing unit 140, and an IoT sensor management unit 150 ), a storage unit 160, a pollution distribution generation unit 170, and the like.

In addition, although the pollution degree information providing server 100 is not illustrated in the drawings, a power supply unit for supplying operating power to each component, an input unit for data input for various functions, an update management unit for managing updates of various operation programs, each component A control unit for collectively controlling the portion may be additionally included.

The communication interface 110 transmits and receives data related to a plurality of IoT sensors 200 that are connected in communication through a network, pollution information about the atmospheric environment and smell, and driving control, and the DMB broadcast server 300 Data transmission is performed for pollution information of each region.

In addition, the communication interface 110 is data for storage and management of pollution information for each region processed by the database 400 and the information generation unit 130 and management information performed by the IoT sensor management unit 150. Send and receive.

The information collection unit 120 collects pollution level information about the air environment and odor from the plurality of IoT sensors 200 through the communication interface unit 110. At this time, the air pollution level information is measurement information for fine dust, ultrafine dust, yellow dust, ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide.

In addition, the information collecting unit 120 periodically receives the pollution level information for the air environment and the odor from the plurality of IoT sensors 200, or the pollution information for the air environment and the odor by the plurality of IoT sensors 200 It is possible to request and receive a measurement.

The information generating unit 130 refers to the pollution level information about the air environment and the odor collected by the information collecting unit 120 and the location information of the plurality of IoT sensors 200, and is classified according to each region. Pollution degree information is generated.

The information providing unit 140 performs a function of transmitting the pollution level information for each region generated by the information generating unit 130 to the DMB broadcasting server 300 through the communication interface 110.

That is, the pollution information for each region provided by the information providing unit 140 is converted into TPEG data by the DMB broadcasting server 300 to be transmitted to the vehicle terminal 500 located in the corresponding region.

At this time, when the information providing unit 140 provides pollution information for each region generated by the information generating unit 130 to the DMB broadcasting server 300, in order to suppress the increase in traffic and to enable large-scale transmission, the Pollution degree information for each region can be distributed and transmitted within a certain period. In this process, the pollution degree information for each unit time may be changed for the same IoT sensor location, or only a difference value of the pollution degree information for each unit time may be transmitted. (See Figure 6)

That is, it is possible to transmit a large amount of data while reducing traffic generation through temporal data compression and coding. Here, when the information providing unit 140 performs data compression and coding, the pollution information for each unit time other than the above-described method is greater than or equal to a reference value for determining the pollution, or the pollution information for each unit time is changed significantly beyond a preset range. Of course, various methods such as sending data can be applied.

The IoT sensor management unit 150 stores the information including the location information of the plurality of IoT sensors 200, the types of sensors provided, the measurement cycle, whether a failure has occurred, operation program update information, or a combination thereof, to the database 400. Store and manage, and performs a function of directly or indirectly controlling the driving of the plurality of IoT sensors 200.

The storage unit 160 stores various operation programs used in the pollution degree information providing server 100, and the pollution degree information about the atmospheric environment and odor collected through the information collection unit 120, and the information generation unit It performs the function of temporarily storing the pollution level information for each region generated in (130).

The pollution distribution generation unit 170 of the air environment and the odor information collected through the plurality of IoT sensors 200 through the information collection unit 120 and each IoT sensor 200 for measuring the pollution level information Pollution distribution map for each region in the form of a map is generated by overlapping preset road information with location information.

At this time, the pollution distribution generation unit 170 sets a predetermined range (for example, 10Km ² ) to one region, and measures the atmospheric environment and odor measured by the plurality of IoT sensors 200 disposed in the region. Pollution degree information can be displayed at a location where the IoT sensor 200 is installed to generate a pollution degree distribution (see FIG. 7 ).

That is, the pollution distribution map for each region is information on which pollution information (ie, measurement information on the air environment and odor) of a location where a plurality of IoT sensors are installed in the corresponding region is installed. Here, the pollution degree information may display the pollution degree information of the atmospheric environment and the odor performed by each IoT sensor 200 in numerical form in digital form or in analog form such as a graph or line.

As described above, when the pollution distribution map generation unit 170 generates a pollution distribution map for each region, the information providing unit 140 compresses and codes the generated pollution distribution map for each region, and then through the communication interface 110. Transmit to the DMB broadcast server 300. In other words, as in the method used to provide pollution information for each region, the entire map information is temporally and spatially compressed and coded to suppress traffic growth and to perform large-scale transmission.

Meanwhile, the pollution distribution generation unit 170 presets the pollution level information and the location information of each IoT sensor 200 for air environment and odor collected from the plurality of IoT sensors 200 by the pollution degree information providing server 100. It is revealed that it may not be used depending on the environment of use because it is an optional configuration used when generating a map-type pollution distribution map by overlapping with road information.

It may further include a control unit to control collectively.

The receiver 510 receives a DMB broadcast signal transmitted from the DMB broadcast server 300.

The TPEG data extractor 520 extracts TPEG data from the DMB broadcast signal received through the receiver 510 to check the pollution level information of the area where the vehicle is currently located, and the pollution degree information to the pollution distribution generation unit ( 540).

The sensor 530 is a variety of sensors including a speed sensor, an acceleration sensor, and a steering sensor provided in a vehicle, and outputs sensing information such as speed, acceleration, and steering angle to the contaminated area confirmation unit 550.

The pollution distribution generation unit 540 overlaps the pollution information for the air environment and the odor included in the pollution information for each region extracted from the TPEG data extraction unit 520 and the road information stored in the location information of the IoT sensor. A pollution distribution map of the area where the vehicle is currently located is generated, and the generated pollution distribution map is output to the pollution area confirmation unit 550.

The contaminated area confirmation unit 550 checks a predicted direction of the vehicle to pass based on the sensing information provided from the sensor 530, and from the contaminated distribution map generated by the pollution distribution map generation unit 540, the vehicle The degree of contamination is checked, and the checked degree of contamination is displayed through the display unit 560.

In addition, the contaminated area checking unit 550 determines whether or not the contamination level in the expected vehicle passage direction confirmed from the contamination distribution map exceeds a preset threshold, and as a result of the determination, the pollution level exceeds the threshold to pollute the vehicle. When it is determined to enter the area, the alarm unit 570 is alerted to enter the contaminated area, and at the same time, the vehicle ventilation control unit 580 controls external air to not enter the vehicle.

On the other hand, if the pollution area identification unit 550 does not generate a pollution distribution map for each region as described above, and directly receives the pollution distribution map of the region where the vehicle is located from the TPEG data extraction unit 520, the pollution distribution map At the same time, when the vehicle is determined to enter the polluted area through the comparison of the pollution degree with a threshold value, a warning is confirmed by checking the degree of contamination in a predicted passage direction of the vehicle based on the sensing information provided from the sensor 530. The vehicle ventilation control unit 580 controls external air to not flow into the vehicle.

The operation of the contaminated area checking unit 550 is an optional configuration that is used only when the pollution distribution map for each region is directly provided from the DMB broadcasting server 300, and thus may not be used depending on the use environment.

The display unit 560 displays the pollution level information of the area where the current vehicle is identified by the contaminated area confirmation unit 550 so that the driver can confirm it.

The alarm unit 570 is provided with a speaker, a vibrator, and the like, and when the vehicle enters the contaminated area as a result of the confirmation of the contaminated area confirmation unit 550, sounds and vibrations are generated to perform an alarm.

In addition, the alarm unit 570 may alarm that the vehicle enters the contaminated area through a method such as blinking the screen of the display unit 560 or displaying an alarm phrase on the screen.

The vehicle ventilation control unit 580 checks the ventilation mode of the current vehicle when the vehicle enters the contaminated area as a result of the confirmation of the contaminated area confirmation unit 550. Block entry into the vehicle.

The storage unit 590 stores various operation programs used in the vehicle terminal 500, threshold values for pollution determination, road information, and the like, and the degree of contamination extracted from the broadcast signal received from the DMB broadcasting server 300. Store the information or distribution of pollution.

Next, an embodiment of a method for providing pollution information to a vehicle through the TPEG standard technology according to the present invention configured as described above will be described in detail with reference to FIGS. 5 to 7. At this time, each step according to the method of the present invention can be changed in order by the environment or those skilled in the art.

5 is a flowchart illustrating in detail an operation process of a method for providing pollution information to a vehicle through the TPEG standard technology according to an embodiment of the present invention, and FIG. 6 illustrates a processing process related to data compression applied to the present invention 7 is a view for explaining a process for checking the degree of contamination in the expected direction of passing through the vehicle from the pollution distribution in the vehicle terminal applied to the present invention.

First, the pollution degree information providing server 100 is connected to the atmospheric environment such as fine dust, ultrafine dust, yellow dust, ozone, nitrogen dioxide, carbon monoxide, sulfur dioxide, etc. measured by a plurality of IoT sensors 200 installed at regular intervals around the road. Pollution degree information and pollution degree information about odor are collected through a network (S100).

In addition, the pollution degree information providing server 100 generates pollution degree information for each region by referring to the pollution degree information about the atmospheric environment and the odor collected in step S100 and the location information of each of the plurality of IoT sensors 200 measuring the pollution degree information. (S200).

In addition, the pollution level information providing server 100 compresses and codes the pollution level information for each region generated through the step S200 to the DMB broadcasting server 300 (S300), and the DMB broadcasting server 300 provides the pollution level information After converting the pollution level information for each region provided from the provision server 100 into TPEG data, the converted TPEG data is loaded on a broadcast signal and transmitted to the vehicle terminal 500 located in each region (S400).

At this time, when the pollution degree information providing server 100 provides pollution information for each region to each vehicle passing through the region using the TPEG technology through the DMB broadcasting server 300, it performs a large-capacity transmission while suppressing traffic increase. In order to do so, the pollution level information for each region is compressed and coded and provided to the DMB broadcasting server 300.

Referring to this in detail with reference to FIG. 6, first, the pollution level information providing server 100 is divided into 10 unit time periods for a predetermined period to compress and code the pollution level information for each region, and the processed pollution level information for the DMB broadcasting server ( It is assumed that it is converted to TPEG data through 300) and transmitted to the vehicle terminal 500.

The pollution degree information providing server 100 transmits a full set of all pollution degree information (for example, a thousand) measured by each IoT sensor 200 located in the corresponding region at the first unit time t time. Then, from the t+1 hour to the unit time of t+9 hour, the pollution degree information is changed among the pollution degree information for each IoT sensor in the current unit time and the pollution degree information for each IoT sensor in the previous unit time for the same IoT sensor location. Select only the ones to be transmitted or send the difference value. In addition, the cycle is initialized and processed from the beginning after the specified 10 unit time passes.

Accordingly, the pollution level information providing server 100 converts the pollution level information for each region to TPEG through the DMB broadcasting server 300 and transmits it to each vehicle terminal 500 while suppressing the increase in traffic as much as possible. It becomes possible.

On the other hand, the vehicle terminal 500 receives the DMB broadcast signal transmitted from the DMB broadcast server 300 through the S400 step, and extracts TPEG data from the received DMB broadcast signal to check the pollution level information for each region ( S500).

In addition, the vehicle terminal 500 is the air pollution and odor information measured by a plurality of IoT sensors 200 located in the region included in the region-specific pollution information identified in step S500 and each IoT sensor measuring the pollution The road information previously stored in the location information of (200) overlaps to generate a pollution distribution map of the corresponding region (S600).

Subsequently, the vehicle terminal 500 checks sensing information such as speed, acceleration, and steering angle measured by various sensors provided in the vehicle, as shown in FIG. 7, and then confirms a vehicle passing direction, and then generates in step S600. A pollution degree in a direction in which a vehicle is expected to pass is checked from a pollution distribution map for each region (S700).

After confirming the degree of contamination in the direction in which the vehicle is expected to pass through the step S700, the vehicle terminal 500 determines whether the degree of contamination in the direction in which the vehicle is expected to pass exceeds a preset threshold (S800). That is, it is determined whether the vehicle enters a contaminated area above a standard.

As a result of the determination in step S800, when the vehicle enters the contaminated area, the vehicle terminal 500 notifies the driver that the vehicle is passing through the contaminated area by performing an alarm such as a sound or an indication, and the air circulation mode of the current vehicle After determining whether is an external circulation mode or an internal circulation mode, if it is set to an external circulation mode, it switches to an internal circulation mode to prevent external air from entering the vehicle (S900).

And the vehicle terminal 500 is repeatedly performed after the step S500 until the pollution degree information providing service is terminated (S1000).

On the other hand, unlike the above description, there may be a case where the TPEG data extracted from the DMB broadcast signal received from the vehicle terminal 500 through the network is not a pollution level information for each region, but a pollution distribution in a map form.

In this case, the vehicle terminal 500 checks a predicted direction of passing of the vehicle based on sensing information such as speed, acceleration, and steering angle measured by various sensors provided in the vehicle, and then checks the pollution degree of the predicted direction of passing of the vehicle from the pollution distribution chart. It is possible to determine whether or not the vehicle passes through the polluted area through the comparison of the checked contamination level with a predetermined threshold. When it is determined that the vehicle passes through the contaminated area, the vehicle terminal 500 performs a vehicle ventilation control to prevent external air from entering the vehicle while performing an alert for passing through the contaminated area.

As described above, the present invention directly overlaps the road information with the pollution information of the atmospheric environment and the odor included in the DMB broadcast signal and the location information of each IoT sensor in the vehicle in operation, or directly generates the pollution distribution map of the driving area, or provides the pollution degree information. After receiving the pollution distribution map of the corresponding area created by overlapping with the road information from the server, and then checking the pollution degree in the expected direction of passing through the vehicle from the pollution distribution map, entering the contamination area above the standard, automatically blocking the external air while performing an alarm and By performing indoor air circulation, a vehicle driver or a passenger traveling in a contaminated area is not exposed to contaminated air, so that the vehicle can be used in a comfortable environment.

In addition, the present invention can solve the inconsistency and inaccuracy of the vehicle's current location and pollution level information caused by the provision of pollution level information for a late atmospheric environment and odor that does not take into account the fast moving situation or direction of the vehicle as in the prior art. In addition, it is possible to easily check the pollution level of a specific area in which a vehicle operates through an existing navigation device without adding a hardware device.

As described above, the present invention has been described with reference to the embodiment shown in the drawings, but this is only exemplary, and those skilled in the art to which the art pertains have various modifications and other equivalent embodiments You will understand that it is possible.
