Parking lot management system that predicts the timing of vehicle leaving {A MANAGEMENT SYSTEM OF PARKING LOT USING SOUND DETECTION}

The present invention relates to a parking lot management system that predicts the timing of leaving the vehicle, and more particularly, by detecting the temperature of the exhaust port of the vehicle parked in the parking area and the emission of hydrocarbons to check whether the vehicle is started, and the departure time and the exit path It relates to a parking lot management system that predicts the timing of the vehicle leaving the parking lot to facilitate the management of the parking lot by predicting the arrival time of and providing it to the driver and to prevent contact accidents with the vehicle inside the parking lot.

Today, large-scale parking lots are divided into several floors and zones in various complex buildings such as offices, apartment-type factories, officetels, apartments (common houses), etc., or buildings in densely populated areas, large marts, department stores, shopping malls, etc.

Such a large parking lot consists of a number of parking blocks (divisions) and aisles.In order to park a vehicle, there is a hassle of finding an empty parking block while driving the aisle.Therefore, a predetermined sensor that can check whether the vehicle is parked for each parking block Is installed, and lights are installed on the ceiling of the passage to ensure inductiveness and convenience for parking.

In addition, since there are no traffic lights in the parking lot, you must go slowly or stop at the intersection, carefully check the left and right, and then enter and pass carefully.When two vehicles encounter each other, they communicate with each other and set the traffic priority to advance the vehicle or go straight ahead. You must yield to your career path.

Therefore, there is a problem in that it takes a long time to park and exit because the vehicle flow in the parking lot is not smooth, and traffic accidents such as contact accidents or collision accidents frequently occur due to the driver's inattention or misjudgment.

That is, parking information is generated by calculating the parking time based on the time when the vehicle enters and exits the parking lot, and the calculated parking time is output through the display unit 14.

In addition, the parking information is transmitted to the parking management system 20 through the communication unit 15, and the operation state of each component is checked to check whether there is an abnormality.

The sensor unit 12 automatically detects when a vehicle enters and exits each parking surface, and transmits the detected signal or data to the controller 11.

However, even with such a system, the technology for predicting when a vehicle parked in a specific area will exit and through which route is not provided, so there is a problem that the vehicle is pushed or a contact accident occurs inside the parking lot. there was.

Wow; In the process of entering the parking lot 30 and parking the vehicle 40 in the parking zone 33, it is determined where the vehicle 40 is parked and to what extent the temperature of the vehicle 40 has risen. A sensor unit 106 that senses in real time and transmits a result value to the vehicle management unit 104; A parking information DB 108 for receiving and storing information on the time when the vehicle 40 parked in the parking area 33 enters, the elapsed parking time, and the time at which the vehicle leaves the vehicle from the vehicle management unit 104; A route setting unit 110 for generating information on an advance route from the parking area 33 in which the vehicle 40 to start and depart is currently parked to the exit route 32; A route guide unit 112 that provides information on an advance route generated by the route setting unit 110 to a driver of the vehicle 40 in an image or audio format; And a risk display unit 114 that transmits a risk factor to the driver through video or audio when there is a risk factor on the expected movement path around the current position of the vehicle 40.

The sensor unit 106 includes a temperature sensor 106a that senses an exhaust port from which combustion gas is discharged from the vehicle 40 and a temperature around the temperature sensor 106a, and an emission of hydrocarbon (HC) discharged from the exhaust port of the vehicle 40 It includes a hydrocarbon sensor (106b) for measuring.

When the driver starts the vehicle 40, the temperature sensor 106a senses the exhaust port of the vehicle 40 and the temperature around the exhaust port and informs the vehicle management unit 104, and the hydrocarbon sensor 106b It detects the amount of hydrocarbons discharged from the vehicle 40 and notifies the vehicle management unit 104, and the vehicle management unit 104 indicates that the vehicle 40 is started and the temperature rises above the reference value so that it is possible to start.

The management system 100 of the present invention checks the path of a vehicle entering and exiting a facility having a space for parking a plurality of vehicles, such as a multi-integrated facility, apartment house, and office building, and quickly and accurately while checking whether the vehicle is parked. It is used to confirm the location of the vehicle. It is also used to accurately predict the entry/exit timing by detecting the state of the vehicle.

The parking lot 30 is a general term for facilities of a general structure, and the access road 31 and the exit road 32 are installed individually or in combination, and a parking area 33 in which individual vehicles 40 can park in the interior space. ) Is provided. The parking area 33 is generally distinguished by a division line.

A moving passageway 34 is formed between the parking zones 33, and the moving passageway 34 is connected to the access road 31 and the exit road 32 to induce entry and exit of the vehicle 40. Typically, since the driver and passengers move through the moving passage 34, it is necessary to prevent a collision between the pedestrian and the vehicle 40 in the moving passage 34.

In addition, since the moving passages 34 inside the parking lot 30 are not wide, it is often difficult for vehicles 40 running in opposite directions to each other. Therefore, it is necessary to prevent congestion from occurring when the vehicle 40 simultaneously enters the moving passage 34, which cannot be intersected.

The management system 100 of the present invention is installed inside the parking lot 30 or at a remote location to check the state of the vehicle 40 entering or exiting the parking lot 30 through an image and sensor information.

To this end, the management system 100 is provided with a control unit 102 that controls the operation of internal components and performs signal conversion and transmission/reception functions. The control unit 102 may be a separate PC or server, and may be a terminal capable of accessing other mobile communication networks.

The vehicle management unit 104 collects and manages information such as the presence, location, and movement direction of the vehicle 40 entering the parking lot 30. The vehicle management unit 104 analyzes the information input from the sensor unit 106 to check the location of the vehicle 40 and the expected entry/exit time point. Then, the information on the confirmed vehicle 40 is stored in the parking information DB 108.

The sensor unit 106 detects in real time where the vehicle 40 is parked in the process of entering the parking lot 30 and parking the vehicle 40 in the parking area 33, and the result value is a vehicle management unit. Forward to 104.

In the present invention, a temperature sensor 106a that senses the temperature around the exhaust port from which combustion gas is discharged from the vehicle 40 and the hydrocarbon sensor that measures the amount of hydrocarbon (HC) discharged from the exhaust port of the vehicle 40 ( 106b) is included in the sensor unit 106. In addition, various types of sensors may be further used to check the presence, position, and direction of movement of the vehicle 40 by transmitting a laser beam or an RF signal to receive a signal reflected from the vehicle 40.

5 is a cross-sectional view showing the type and location of a sensor unit installed inside a parking area, and FIG. 6 is a plan view showing the location of a temperature sensor and a hydrocarbon sensor.

The temperature sensor 106a is installed on the floor or wall surface of the parking area 33 and is configured to sense an exhaust port installed at the rear of the vehicle 40 and the temperature around it. It is preferable that the temperature sensor 106a is installed in a position that can easily detect heat generated from the vehicle. Typically, it will be advantageous in terms of detection efficiency to be installed on the floor surface close to the exhaust port or on the wall surface behind the parking area 33. The temperature sensor 106a may be a general thermometer, and in addition, an infrared temperature sensor or the like may be used. In addition, it is also possible to indirectly infer the temperature of the vehicle 33 by measuring the temperature of the air below or behind the exhaust port instead of measuring the temperature of the exhaust port installed in the vehicle 40.

The hydrocarbon sensor 106b measures the amount of various hydrocarbons (HC) discharged from the exhaust port of the vehicle 40.

Hydrocarbons are one of the substances generated as a result of combustion of fuel in the engine of the vehicle 40, and since most of them are carcinogens, emissions are strictly reduced. Hydrocarbons include propene, toluene, ethane, benzene, formaldehyde, and the like. In addition, various types of hydrocarbons are discharged from the exhaust port of the vehicle 40.

Hydrocarbons are mostly oxidized by three-way catalysts (TWCs) installed in the vehicle 40, but these three-way catalysts exhibit activity at temperatures above about 200-300°C, and low-temperature start-up where the three-way catalyst does not show activity. Hydrocarbons equivalent to 50-80% of total hydrocarbon emissions are released from the section. That is, immediately after the vehicle 40 is turned on, the hydrocarbon is not oxidized by the three-way catalyst and is discharged into the air, so the fact that the vehicle 40 is immediately after the engine and the temperature of the exhaust port are reduced. You can see that it hasn't risen enough.

The hydrocarbon sensor 106b is preferably installed on the bottom or rear wall of the exhaust port so that hydrocarbons discharged from the exhaust port can be efficiently collected and analyzed. The hydrocarbon sensor 106b includes an inhaler for generating a negative pressure for collecting hydrocarbons, and a sensing means for measuring and quantifying the amount of hydrocarbons. Information on the amount of hydrocarbons detected and calculated by the hydrocarbon sensor 106b is transmitted to the vehicle management unit 104 through a wired or wireless communication module.

Depending on the size, displacement, and design of the vehicle, the number and location of exhaust ports may vary. In many cases, large vehicles released recently have two exhaust ports, and in some cases, only one is installed at the rear of the vehicle. Therefore, it is desirable to install two or more temperature sensors 106a and 106b in order to accurately grasp the temperature and hydrocarbon emissions of the vehicle 40.

When a plurality of temperature sensors 106a and hydrocarbon sensors 106b are installed, values measured by all sensors may be averaged and used, or one of a maximum value, a minimum value, and an intermediate value may be used as a representative value.

The stopper 35 attached to the bottom of the parking area 33 is a component that prevents the vehicle 40 from approaching the rear. When installing the temperature sensor 106a and the hydrocarbon sensor 106b on the floor, it is preferable to install it on the bottom surface between the rear wall surface and the stopper 35.

The parking information DB 108 stores information on the time when the vehicle 40 parked in the parking area 33 enters, the elapsed parking time, and the time at which the vehicle leaves the vehicle. Information on whether the vehicle 40 is present in the specific parking area 33 is also stored in the parking information DB 108.

The route setting unit 110 generates information on an advance route to be provided to the driver of the vehicle 40 to turn on the engine and depart. The route setting unit 110 calculates the most efficient route from the parking area 33 in which the vehicle 40 is currently parked to the exit route 32. The route setting unit 110 creates a route by referring to the number and location of vehicles 40 that have entered the current parking lot 30, a moving route, and the like, and adding information on the congestion level of the moving passage 34. It is preferable to predict the congestion degree of the movement path 34 by referring to the movement path information collected in the past as well as real-time information collected through the sensor in the current state.

The route guide unit 112 is configured in the form of a display, and provides information on an efficient moving route to the driver of the vehicle 40 through video or audio. Since information needs to be transmitted to a driver sitting inside the vehicle 40, a relatively large display panel may be used or a simple arrow-shaped indicator may be used to intuitively transmit the moving direction or the rotation direction.

The danger display unit 114 predicts a movement route based on the current position of the vehicle 40, and when there is a risk factor on the expected movement route, it transmits it to the driver through video or audio. When the vehicle 40 passes through the movement passage 34, when the vehicle 40 is expected to leave the parking area 33 in contact with the movement passage 34, the vehicle 40 is displayed through the danger display unit 114, To prevent accidents such as collisions.

In addition, when there is a pedestrian passing through the movement path 34, the danger display unit 114 may also display this to the driver in an image or audio, thereby preventing a personnel accident from occurring.

In addition, the danger display unit 114 may indicate that the preheating of the vehicle 40 is insufficient by using information on the temperature of the exhaust port of the vehicle 40 and the amount of hydrocarbons discharged. As described above, since the emission of hydrocarbons varies depending on the temperature of the engine, the exhaust port of the vehicle 40, and the three-way catalyst, it is possible to indirectly check the temperature state of the vehicle 40 by measuring the emission of hydrocarbons.

The danger display unit 114 considers that the temperature increase of the engine and the three-way catalyst has not been sufficiently increased when the hydrocarbon emission rapidly increases after the vehicle 40 is started, and displays this to the driver as an image or audio. When the emission of hydrocarbons is lower than a certain standard or the reduction ratio of the emission is more than a certain level, the danger display unit 114 reports that the temperature of the vehicle 40 has risen sufficiently, and displays a state in which the vehicle can be taken out.

Preferably, the vehicle management unit 104 considers that the vehicle 40 is turned on while the vehicle 40 is cooled when the temperature of the exhaust port increases as the emission of hydrocarbons increases. In addition, when the temperature of the exhaust port continuously increases and the emission of hydrocarbons starts to decrease, the vehicle management unit 104 regards the heating to the extent that the operation of the three-way catalyst installed in the vehicle 40 starts. When the temperature of the exhaust port does not rise at the minimum state, or when the emission of hydrocarbons falls below the standard value, it is reported that the temperature has risen to the extent that the vehicle 40 can start, and the danger display unit 114 indicates that the vehicle 40 exits Indicates possible.

The fee calculation unit 116 calculates the parking fee according to the parking time of the vehicle 40 and transmits the information to the control unit 102. The control unit 102 transmits the input parking fee to a fee storage device (not shown) so that the fee is received when the vehicle is leaving the vehicle. The fare calculation unit 116 is set to calculate the parking fee in advance by calling information on the vehicle 40 parked at the time when the vehicle 40 is started and the vehicle is expected to leave the vehicle. The fare calculation unit 116 is not at the time when the vehicle 40 reaches the entrance of the parking lot 30, but starts to turn on the engine and prepares for leaving the vehicle to increase the temperature of the engine or exhaust port of the vehicle 40 and exceed the reference temperature. One point in time can be set as the parking end time. Through this, it is possible to induce continuous use of the parking lot 30 while having an effect of partially discounting the parking fee to the driver of the vehicle 40.

The communication module 118 forms a communication network to exchange communication signals with the management system 100 and an external system. The driver can access the management system 100 through a smartphone application or the like. The controller 102 provides the driver of the vehicle 40 through the communication module 118 with information on the parking status and parking zone 33, the estimated parking fee, and the number of vehicles 40 in the current parking lot 30. And information about the congestion level of the mobile passage 34 and the like can be transmitted.

After the driver parks the vehicle 40, a certain estimated parking time is input through an application. If the vehicle 40 is turned on before the estimated parking time elapses, the sensor unit 106 detects it and transmits it to the control unit 102. The control unit 102 notifies that the vehicle 40 has been started with the driver's smartphone through the communication module 118. When the temperature of the exhaust port detected by the temperature sensor 106a increases, and the emission of hydrocarbons detected by the hydrocarbon sensor 106b increases, the control unit 102 regards the vehicle 40 as being turned on. The driver may report the theft through the application if the vehicle 40 is turned on even though he or she does not drive himself. In this case, by preventing the gate at the entrance and exit of the parking lot 30 from being opened, the stolen vehicle 40 cannot escape to the outside.

On the other hand, Figure 7 is a flow chart showing a method of managing the parking state of a vehicle using the management system of the present invention, Figure 8 shows a state in which the emission of hydrocarbons changes according to the temperature increase immediately after the vehicle is turned on. It is a graph.

First, the vehicle 40 enters the parking lot 30, checks the empty parking area 33, and enters the vehicle 40 inside the parking area 33 (S102). A sensor installed in the parking area 33 is installed. The unit 106 detects the entry of the vehicle 40 and notifies the vehicle management unit 104 of the entry. When the vehicle 40 enters the parking area 33 where the vehicle 40 did not exist, the temperature detected by the temperature sensor 106a increases, and the emission of hydrocarbons detected by the hydrocarbon sensor 106b suddenly increases. Through this, it can be confirmed that the vehicle 40 is entered. The vehicle management unit 104 stores the parking fact in the parking information DB 108. In the parking information DB 108, the entry time of the vehicle 40 is also input.

When a predetermined time elapses while the vehicle 40 is parked, the vehicle management unit 104 continuously monitors whether a change in the vehicle 40 occurs in the sensor unit 106.

When the driver boards the vehicle 40 and starts the engine to unload the vehicle 40, the temperature sensor 106a and the hydrocarbon sensor 106b detect heat and hydrocarbons generated from the vehicle 40 (S104). The temperature sensor 106a and the hydrocarbon sensor 106b inform the vehicle management unit 104 that the vehicle 40 has been started.

As shown in FIG. 8, while the vehicle 40 is started and preheating is not sufficiently performed (cooling section), the amount of hydrocarbon discharged rapidly increases. However, after the temperature of the engine, exhaust port, and the three-way catalyst sufficiently rises (heating section), the emission of hydrocarbons rapidly decreases.

The vehicle management unit 104 sets a time (referred to as an'estimated departure time' in the present invention) from when the engine is turned on until the vehicle 40 actually leaves the vehicle. (S106) Typically, in winter, the engine is preheated. It takes more time, so the estimated departure time may vary depending on the season. The estimated departure time is the'time from when the vehicle is started and the temperature of the vehicle is sufficiently increased to the actual start of operation' predicted by the management system 100.

The vehicle management unit 104 transmits a danger indication signal to the danger display unit 114 when the set estimated departure time elapses. The danger display unit 114 notifies the danger of exiting the vehicle 40 by video or audio according to the input danger display signal. (S108) The danger display is the driver of another vehicle 40 or the movement path 34 Make sure you can reach pedestrians.

If the vehicle 40 parked in the specific parking area 33 is started and the estimated departure time is imminent, if there is a pedestrian passing through the exit path of the vehicle 40, the possibility of colliding with the vehicle 40 will increase. In order to prevent such an accident, the danger display unit 114 notifies drivers and pedestrians around the vehicle 40 that the vehicle 40 is about to start when the departure of the vehicle 40 is imminent.

The vehicle management unit 104 transmits a route guide signal to the route guide unit 112. After receiving the route guide signal, the route guide unit 112 sets the route of the vehicle 40 and displays it to the driver. (S110) The route guide unit 112 sets an exit route at the place where the vehicle 40 is currently located. Calculate the fastest and safest route to (32). For calculating the route, refer to the number of vehicles 40 parked in the other parking areas 33, the estimated departure time of the other vehicles 40, and the degree of congestion of the moving path 34.

In addition, it is preferable to set a path so as to avoid this area if there is a delayed intersection point due to the high degree of congestion of the vehicle 40.

When the vehicle 40 completely exits the parking lot 30 through the exit path 32, the vehicle management unit 104 induces the parking of the new vehicle 40 by deleting the record stored in the parking information DB 108.

Meanwhile, FIG. 9 is a flowchart illustrating a state in which notification is performed at each time point after the vehicle is turned on.

As described above, when the vehicle 40 starts parking and after a certain period of time elapses, when the vehicle 40 detects high temperature heat and hydrocarbon emissions, it is considered that the vehicle 40 will leave the vehicle soon. After the engine is turned on and the temperature is sufficiently increased, the time until the vehicle 40 is expected to leave the vehicle is the estimated departure time.

The vehicle 40 may pass not only a straight section but also a rotation section or an intersection section until the vehicle 40 passes the moving passage 34 and leaves the exit route 32. In the present invention, a means for guiding a route to a place where the driver needs to pay special attention is used. That is, a route guide unit 112 and a danger display unit 114 are installed in the rotation section or the cross section, respectively.

When the vehicle 40 leaves the parking area 33, a path guide unit 112 installed in the front portion of the parking area 33 (in front of the vehicle traveling direction) guides the moving path of the vehicle 40. In addition, if the vehicle 40 moves in the direction where it meets the intersection, it provides guidance. In the present invention, the first intersection section through which the vehicle 40 passes is referred to as a “first intersection”. In addition, the time until reaching the first intersection after leaving the parking area 33 is referred to as the'first expected time'. In general, if there is no special matter in the moving passage 34, the time it takes to reach the first intersection after leaving the parking area 33 will be the same as the first estimated time.

When the first estimated travel time has elapsed, the route guide unit 112 installed at the first intersection displays the next route of the vehicle 40 in video or audio. At the intersection, it is possible to inform the driving route of the vehicle 40 in various ways, such as going straight, turning left and right, or making a U-turn.

The second estimated time is calculated based on the time it normally takes from the first intersection to the second intersection. The route guide unit 112 guides a different route to the driver at the second intersection when the second estimated time has elapsed.

In this way, the driver can be informed of the route until reaching the N-th intersection every time the N-th estimated time elapses.

When the vehicle 40 completely exits the area of the parking lot 30 through the exit path 32, such route guidance is terminated.
