Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a configuration diagram of a vehicle idling prevention system of the present invention. 2 is a plan view of a parking area in which a vehicle idling prevention system is implemented according to an embodiment of the present invention. 3 is a front view of a parking area in which a vehicle idling prevention system is implemented according to an embodiment of the present invention. 4 is a side view of a parking area in which a vehicle idling prevention system is implemented according to an embodiment of the present invention. 5 is a diagram showing extraction of a vehicle number from a license plate image according to an embodiment of the present invention.

1 to 4, the vehicle idling prevention system of the present invention is installed on one side of the wall to detect the presence or absence of a vehicle and measures the distance to the vehicle. Acquiring sensor information from a piezoelectric sensor 200 generating current, the distance sensor 100, and the piezoelectric sensor 200, comparing the sensor information with a preset reference value to determine idle operation, and generating a control signal A control unit 300, a notification unit 400 for providing a notification according to the control signal, a camera 500 for photographing the license plate of the vehicle according to the control signal, and recognizing the vehicle number of the license plate photographed by the camera 500 and a server 600 that transmits a notification message based on the driver's phone number pre-stored together with the vehicle number.

More specifically, the distance sensor 100 may be installed on one side of a wall surface to emit infrared rays, and may output a time t for the infrared rays to be emitted and reflected on one side of the vehicle to return as sensor information. Then, the control unit 300 uses the time t for the infrared ray, which is the sensor information obtained from the distance sensor 100, to be emitted and reflected on one side of the vehicle to return, the infrared ray preset in the distance sensor 100. The distance (s) to the vehicle can be measured by multiplying the emission rate (v) of the time (t).

Here, the distance sensor 100 may measure a distance within a range of 20 cm to 150 cm, and the control unit 300 is most preferably in a parking area of an underground parking lot when the distance (s) from the vehicle is within a range of 75 cm to 85 cm. It may be determined that the vehicle is parked. In general, the standard of any parking area in an underground parking lot is set to 5m in length and 2.5m in width, and the bump is installed within 1/4 to 1/8 of the length. And the driver parks the vehicle as close as possible to the bump, so the control unit 300 sets the range of 75cm to 85cm included within 1/4 to 1/8 of the total length of the parking area as a standard, and 80cm is the distance from the vehicle. It is most desirable to determine the presence or absence of a vehicle with the reference value of (s).

Meanwhile, as shown in FIGS. 3 and 4 , the distance sensor 100 may be installed within a range of 80 cm to 90 cm from the ground when installed on one side of a wall. This is an appropriate range in which infrared rays are reflected without passing through when infrared rays are emitted from the rear or front of the vehicle, considering the overall height of various types of vehicles such as small trucks, sedans, and SUVs.

Next, resistance of the piezoelectric sensor 200 changes as pressure is applied, so that the weight and vibration of the vehicle can be sensed with the sensor. That is, it is most preferable that the piezoelectric sensor 200 is widely installed on the ground in contact with wheels in an arbitrary parking area in an underground parking lot. In addition, when the vehicle is parked in the parking area, pressure is applied according to the weight of the vehicle. When the vehicle is idling, the weight applied to the piezoelectric sensor 200 changes slightly as the vehicle body and wheels vibrate. The magnitude of the current may be output as sensor information.

Also, the control unit 300 may compare sensor information obtained from the piezoelectric sensor 200 with a preset reference value to determine whether the vehicle is idling. Here, the predetermined reference value may be within the range of 2 minutes to 5 minutes, and most preferably, 2 minutes may be used as the reference value. That is, if it exceeds 2 minutes from the time when the presence or absence of a vehicle is determined through the distance (s) from the control unit 300 to the vehicle, and the engine does not turn off continuously and vibration occurs in the vehicle body and wheels, it is judged to be idling. Because that's enough time. In addition, referring to the ordinances of each local government, a fine can be imposed after warning the driver if the engine is continuously turned on for 2 to 5 minutes in an idling restricted area including terminals, garages, school environmental hygiene purification areas and parking lots. there is. Based on these ordinances, the control unit 300 can generate the control signal to notify idling when 2 minutes are exceeded, and then transmit the control signal to the notification unit 400 and the camera 500, respectively.

Next, the notification unit 400 most preferably may include an LED lamp 410 to visually inform the site of the corresponding location in real time, and a speaker 420 to audibly inform the site of the corresponding location in real time. ) may be included.

For example, if the vehicle is not in the corresponding parking area or simply parked, the LED lamp 410 may output an OFF state or a standard color, and when the control signal is transmitted to the LED lamp 410, it turns ON. It can be output after being changed or changed from the standard color to another color. Alternatively, when the control signal is transmitted to the speaker 420 of the notification unit 400, a specific sound may be output. On the other hand, the notification unit 400 may be installed at a distance of 170 cm to 180 cm or more from the ground on a wall surface so that a manager can grasp the output color of the LED lamp 410 even from a long distance regardless of the height of the vehicle.

Accordingly, there is a remarkable effect of allowing the manager to easily check the location where idling occurs in a wide underground parking lot and take action quickly. In addition, there is a remarkable effect of alerting the driver of the vehicle to idling in real time even to the driver who is inside the vehicle in an idling state without turning off the engine unconsciously.

Next, the camera 500 may receive the control signal at the same time as the notification unit 400, and take pictures according to the control signal. In addition, as shown in FIGS. 3 and 4 , the camera 500 may most preferably be installed on one side of a wall so as to recognize a license plate of a vehicle. In general, the total height of a vehicle varies depending on the type of vehicle, but a sedan has a range of 140 cm to 150 cm, and an SUV has a range of 150 cm to 170 cm. In addition, as the height of the camera 500 increases at the same distance, the camera 500 is most preferably installed with a height within a range of 90 cm to 100 cm from the ground. That is, there is a remarkable effect of easily recognizing a license plate regardless of a vehicle type.

In addition, as shown in (h) of FIG. 5 , the server 600 detects 'idling of the driver's 00 vehicle' based on the previously stored driver's phone number. Please turn off the engine.” can be sent as an SMS message. In other words, the server 600 can acquire vehicle numbers and phone numbers of all drivers who visit the underground parking lot by enabling driver terminals to access the web or application based. In addition, the obtained vehicle number and phone number may be stored in a database in correspondence with each other. At this time, the stored vehicle number and phone number may be owned only for a certain period of time according to the Information Protection Act and all may be discarded.

In addition, the server 600 receives the RGB image including the vehicle number photographed from the camera 500, and then uses an image converter 610, an outline extractor 620, and a vehicle number to extract the corresponding vehicle number. An extraction unit 630 may be included.

The image conversion unit 610 may convert the license plate photographed by the camera 500 from an RGB image to a black and white image so as to recognize the vehicle number, and maximize the black and white contrast. For example, the image conversion unit 610 may convert the RGB image of FIG. 5 (a) into a black and white image of FIG. 5 (b) and maximize the contrast between black and white.

Next, the contour extraction unit 620 may extract the contour of the license plate by adaptively thresholding the license plate converted into the black and white image. Here, the threshold processing is for simplifying the black-and-white image and removing noise, and the adaptive threshold processing is to reduce the black-and-white image to a small size to solve the problem that some areas are all white or all black when the shades are different in one black-and-white image. It is threshold processing by area. That is, the contour extractor 620 can clearly extract the contours of license plates and vehicle numbers, which are desired regions, from the black and white image as shown in (c) of FIG. 5 .

Next, the vehicle number extraction unit 630 may extract the vehicle number based on the size and arrangement of the outline. Since the outline of the license plate and license plate number extracted from the contour extractor 620 is an analog shape that cannot be confirmed by a machine, the contour can be transformed into a digital rectangular shape as shown in (d) to (e) of FIG. there is. And, as shown in (f) to (g) of FIG. 5, the license plate can be finally recognized by using the characteristics of the size and arrangement of the outline deformed in a rectangular shape.

Next, the present invention is designed to reduce harmful gas emissions, ultimately contribute to carbon neutrality and improve environmental problems, and there is a need to provide benefits according to environmental problem improvement to managers who apply the present invention to underground parking lots. there is. In order to solve this problem, the present invention may further include an air quality measurement sensor 700 for measuring at least one of exhaust gas and fine dust including NO ₂ and CO so as to detect air quality around the installation.

Here, when NO ₂ is less than 0.02 ppm (step 1), the pollutant does not affect the human body. And 0.02ppm to 0.04ppm (level 2) can increase mild respiratory symptoms by 20% when children are chronically exposed. And 0.05ppm to 0.07ppm (level 3) can cause allergic reactions and structural and functional changes in the lungs of asthmatic patients due to chronic exposure. 0.08ppm to 0.09ppm (level 4) may cause mild respiratory symptoms in case of chronic exposure. 0.1ppm to 0.19ppm (level 5) can cause effects such as lung function, airway resistance, and respiratory symptoms in patients with chronic obstructive pulmonary disease. And if it is more than 0.2ppm (step 6), there is a possibility of inducing biochemical changes due to cell degeneration.

If CO is less than 2.0ppm (stage 1), it is the average concentration that can be maintained at less than 2.5% of COHb in the blood. 2.0ppm to 4.4ppm (stage 2) may slightly increase the COHb in the blood of the sensitive group than the normal value during chronic exposure. 4.5ppm to 8.9ppm (level 3) can cause hypoxia and ischemic heart disease due to an increase in COHb in the blood of sensitive groups during chronic exposure. 9.0ppm to 15.4ppm (step 4) increases blood COHb in the sensitive group when exposed for more than 8 hours, and increases blood COHb in the general public when exposed chronically. 15.5ppm to 24.9ppm (step 5) causes an increase in COHb in the blood of the general public when exposed for more than 8 hours. 25ppm or more (level 6) causes an increase in COHb in the blood of the general public when exposed for 1 hour.

For fine dust in Korea, 0 to 30 (μm/m ² ) is good, 31 to 80 (μm/m ² ) is normal, 81 to 150 (μm/m ² ) is bad, and 151 (μm/m 2 ). ² ) above can be classified as very bad.

That is, the air quality measuring sensor 700 can numerically measure air quality including exhaust gas including NO ₂ and CO and fine dust in the surroundings, which is air quality information.

In addition, the server 600 may further include a carbon credit acquisition unit 640 and a carbon credit trading unit 650 to provide a manager with a benefit according to environmental problem improvement using the air quality information. More specifically, the carbon credit acquisition unit 640 acquires and stores air quality information from the air quality measurement sensor 700 at predetermined intervals, and obtains carbon credits according to the degree that the current air quality information is lower than the previous air quality information. can do.

For example, if the air quality measurement sensor 700 measures only one of NO ₂ , CO, and fine dust, and the previous air quality information is level 3 and the current air quality information is level 2, environmental improvement is achieved by one step from level 3 to level 2. As a result, it is possible to obtain carbon credits corresponding to the promotion to one level. Alternatively, if the air quality sensor 700 measures two or more of NO ₂ , CO, and fine dust, NO ₂ is promoted from step 4 to step 3, and fine dust is promoted from very bad to normal, the average It is possible to obtain carbon credits corresponding to a step-by-step promotion.

Next, when the carbon credit trading unit 650 receives carbon credit trading request information from the manager terminal, it may trade according to the current market price of the carbon credits. That is, the carbon credits trading unit 650 may be connected to the carbon credits trading market system over a network and may be connected to the manager terminal for wireless communication. That is, the manager terminal may display the number of carbon credits obtained from the carbon credits acquisition unit 640, and the trading request information includes a purchase request for purchasing more carbon credits in the carbon credits trading market system and the acquired carbon credits. A solicitation to sell permits may be included.

If the carbon credits are not obtained from the carbon credits acquisition unit 640 for a long period of time, the manager transmits trading request information to the carbon credits trading unit 650 through the manager terminal. In this case, carbon credits traded at the current market price can be purchased according to the appropriate purchase amount included in the transaction request information.

Conversely, if a plurality of carbon credits are acquired from the carbon credits acquisition unit 640, the manager may transmit a sale request to the carbon credits trading unit 650 through the manager terminal, and the carbon credits trading unit 650 may market In this case, the carbon credits traded at the current market price can be sold according to the appropriate selling amount included in the trading request information. Accordingly, the manager of the underground parking lot implementing the vehicle idling prevention system of the present invention can obtain additional benefits through carbon credits, which has a very useful effect in encouraging the manager's will to actively realize environmental improvement.

Control method of vehicle idling prevention system

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings. 6 is a flowchart of a control method of a vehicle idling prevention system according to the present invention.

Referring to FIG. 6 , the control method of the vehicle idling prevention system of the present invention includes a vehicle presence determination step (S100), an idling determination step (S200), a notification step (S300), a photographing step (S400), a license plate recognition step (S500). ) and message transmission step (S600).

More specifically, in the vehicle presence determination step (S100), the presence or absence of a vehicle is determined by using the sensor information obtained from the distance sensor 100 by the control unit 300. That is, in the vehicle presence determination step (S100), the infrared ray, which is the sensor information obtained from the distance sensor 100, is emitted and reflected on one side of the vehicle, and the return time t is used to detect the distance sensor 100. The distance s to the vehicle can be measured by multiplying the predetermined infrared ray emission rate v and the time t. And, if the distance (s) with the vehicle is within 75 cm to 85 cm, it may be determined that the vehicle is parked in the parking area of the underground parking lot.

In general, the standard of any parking area in an underground parking lot is set to 5m in length and 2.5m in width, and the bump is installed within 1/4 to 1/8 of the length. In addition, the driver parks the vehicle as close as possible to the bump, so the range of 75cm to 85cm included within 1/4 to 1/8 of the total length of the parking area is standard, and 80cm is the standard value of the distance (s) from the vehicle. It is most preferable to determine the presence or absence of a vehicle.

Next, in the idling state determining step (S200), the sensor information obtained from the piezoelectric sensor 200 is determined by the control unit 300 to determine whether the vehicle is idling, and if it is determined that the vehicle is idling, control is performed. A signal is generated.

That is, when the vehicle confirmed from the vehicle existence determination step (S100) is parked in the corresponding parking area, pressure is applied to the piezoelectric sensor 200 according to the weight of the vehicle, and when the vehicle is idling, the vehicle body and wheels vibrate Accordingly, the weight applied to the piezoelectric sensor 200 is minutely changed, and the magnitude of current according to the change may be output as sensor information. Then, in the idling state determination step (S200), the sensor information obtained from the piezoelectric sensor 200 may be compared with a preset reference value, and 2 minutes from the time when the presence or absence of a vehicle is determined in the vehicle existence determination step (S100). It may be determined that the vehicle is idling if it exceeds and the ignition is not turned off continuously and vibration is generated in the vehicle body and wheels.

Referring to ordinances by local governments, fines can be imposed after warning the driver if the engine is continuously turned on for 2 to 5 minutes in areas where vehicle idling is restricted, including terminals, garages, school environmental sanitation purification areas, and parking lots. Based on these ordinances, in the idling state determination step (S200), the control signal can be generated to notify the manager or driver that idling is in progress when the predetermined reference value of 2 minutes is exceeded, and the notification unit 400 and the camera ( 500) can be transmitted to each.

Next, in the notification step (S300), notification is provided by the notification unit 400 according to the control signal. For example, if the vehicle is not in a corresponding parking area or simply parked, the LED lamp 410 of the notification unit 400 may be in an OFF state or a standard color may be output. On the other hand, in the notification step (S300), when the control signal is transmitted to the LED lamp 410, it may be changed to an ON state or changed from a standard color to another color and output. In addition, in the notification step (S300), when the control signal is transmitted to the speaker 420 of the notification unit 400, a specific sound may be output.

Accordingly, there is a remarkable effect of allowing the manager to easily check the location where idling occurs in a wide underground parking lot and take action quickly. In addition, there is a remarkable effect of alerting the driver of the vehicle to idling in real time even to the driver who is inside the vehicle in an idling state without turning off the engine unconsciously.

Next, in the photographing step (S400), the license plate of the vehicle is photographed by the camera 500 according to the control signal. The photographing step (S400) may be photographed as an RGB image including the license plate of the vehicle and other backgrounds.

Next, in the vehicle number recognition step (S500), the vehicle number of the license plate captured by the camera 500 is recognized by the server 600. The vehicle number recognition step (S500) includes an image conversion step (S510), an outline extraction step (S520), and a vehicle in order to extract the corresponding vehicle number after receiving the RGB image including the vehicle number photographed from the camera 500. A number extraction step (S530) may be included.

First, in the image conversion step (S510), the license plate photographed from the camera 500 is converted from an RGB image to a black and white image by the image conversion unit 610 in the server 600 so that the license plate number can be recognized. and black-and-white contrast can be maximized. For example, in the image conversion step (S510), the RGB image of FIG. 5 (a) is converted into the black and white image of FIG. 5 (b), and the contrast between black and white can be maximized.

Next, in the contour extraction step (S520), the license plate converted to the black and white image is adaptively thresholded by the contour extractor 620 in the server 600 to extract the contour of the vehicle number.

Here, the thresholding process is for simplifying the black-and-white image and removing noise, and the adaptive thresholding process is for solving the problem that when a black-and-white image has different shades, some areas are all white or all black, the black-and-white image is small. It is thresholded by region. That is, in the contour extraction step (S520), as shown in (c) of FIG. 5, the contours of the license plate and vehicle number, which are desired regions, can be clearly extracted from the black and white image.

Next, in the vehicle number extraction step (S530), the vehicle number can be extracted based on the size and arrangement of the outline by the vehicle number extraction unit 630 in the server 600. Since the outline of the license plate and license plate number extracted from the contour extraction step (S520) is an analog shape that cannot be confirmed by the machine, the contour can be transformed into a digital rectangular shape as shown in (d) to (e) of FIG. there is. And, as shown in (f) to (g) of FIG. 5, the license plate can be finally recognized by using the size and arrangement characteristics of the outline deformed in a rectangular shape.

Next, in the message transmission step (S600), a notification message is transmitted by the server 600 based on the driver's phone number pre-stored together with the vehicle number. For example, in the message transmission step (S600), based on the pre-stored driver's phone number, 'idling of the driver's 00 vehicle has been detected. Please turn off the engine.” An SMS message may be sent.

The server 600 can obtain vehicle numbers and phone numbers of all drivers who visit the underground parking lot by enabling driver terminals to access the web or application-based. In addition, the obtained vehicle number and phone number may be stored in a database in correspondence with each other. At this time, the stored vehicle number and phone number may be owned only for a certain period of time according to the Information Protection Act and all may be discarded.

Next, the present invention is designed to reduce harmful gas emissions, ultimately contribute to carbon neutrality and improve environmental problems, and it is necessary to provide benefits according to environmental problem improvement to managers who apply the present invention to underground parking lots. there is.

Therefore, the present invention is an air quality measurement step (S700) in which at least one of exhaust gas and fine dust including NO ₂ and CO is measured by an air quality sensor, by the carbon credit acquisition unit 640 in the server 600 , A carbon credit acquisition step (S800) in which air quality information is acquired and stored from the air quality measurement sensor 700 at predetermined intervals, and carbon credits are obtained according to the degree that the current air quality information is lower than the previous air quality information (S800) and the server ( 600) by the carbon credits trading unit 650, when carbon credits trading request information is received from the manager terminal, a carbon credits trading step (S900) of trading according to the current market price of the carbon credits may be included.

For example, in the air quality measuring step (S700), air quality including exhaust gas and fine dust including NO ₂ and CO around the installation may be numerically measured, which is air quality information.

And, if only one of NO ₂ , CO, and fine dust is measured from the air quality measuring step (S700), and the previous air quality information is level 3 and the current air quality information is level 2, environmental improvement is achieved by one level from level 3 to level 2 In the step of acquiring carbon credits (S800), carbon credits corresponding to a one-step promotion may be obtained. Alternatively, if two or more of NO ₂ , CO, and fine dust are measured from the air quality measuring step (S700), NO ₂ is promoted from step 4 to step 3, and fine dust is promoted from very bad to normal, the carbon In the step of acquiring emission credits (S800), carbon emission credits corresponding to the average of the above steps may be acquired.

And, the number of carbon credits obtained from the carbon credits acquisition step (S800) may be displayed on the manager terminal, and the purchase request for purchasing more carbon credits in the carbon credits trading market system and the carbon credits acquisition step A sale request for selling the carbon credits obtained from (S800) may be included. That is, in the carbon emission trading step (S900), when a purchase request is transmitted through the manager terminal, the carbon emission rights traded at the current market price in the carbon emission trading market can be purchased according to the appropriate purchase amount included in the transaction request information. . Conversely, when a sale request is transmitted through the manager terminal, the carbon credits currently being traded in the market can be sold at an appropriate sale price included in the sale request information.

Accordingly, the manager of the underground parking lot implementing the vehicle idling prevention system of the present invention can obtain additional benefits through carbon credits, which has a very useful effect in encouraging the manager's will to actively realize environmental improvement.
