Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking distance control apparatus,

More particularly, the present invention relates to a method and system for deriving distance information of a user from a vehicle to a wall of a parking lot by using a beacon, And transmits a warning message to the mobile terminal of the user aboard the vehicle warning of the possibility of collision with the wall surface of the parking lot when the vehicle approaches the wall surface of the parking space less than the limit distance to prevent the vehicle from colliding against the parking wall surface The present invention relates to a parking distance control system and a parking distance control method.

In large buildings such as apartments, commercial buildings, department stores, large marts, and office buildings, many parking spaces are reserved for parking lots. Parking spaces are limited by parking lines formed on the ground, And the parking space is secured in the form of such as.

Such a parking lot in a building such as a parking building or an underground parking lot must move the vehicle to an upper level or a basement level based on the ground in order for the vehicle to park in the parking space. At this time, the vehicle moves in a curved ramp having a narrow turning radius as shown in Fig. 1 to park the vehicle in the parking lot line.

However, when driving a curved ramp to enter a parking lot to park such a vehicle, there is a case in which the front bumper or the side surface of the vehicle collides against the wall due to curved advancement, as shown in Fig. 1 It is occurring frequently.

In addition, even when entering the parking lot safely, if there are a large number of concrete columns or walls around a parking lot in a parking building or an underground parking lot, an inexperienced driver frequently damages the front, rear, or side of the vehicle.

The above-mentioned accidents have a problem in that, when the vehicle enters the slope of the curved road curve, if the vehicle crashes on the curved ramp due to insufficient driving, the following vehicle collides continuously and the incidence of safety accidents is high.

Therefore, in recent years, when the parking lot is entering the curved ramp, the driver is able to visually detect that the driver hits the curved wall while the curved ramp is on the curved ramp. However, since the mirror is not frequently experienced by the driver, There is still a problem that the front and rear sides of the vehicle are damaged due to miscomprehension of the inexperience and the sense of distance. Therefore, there is a growing need for techniques to solve this problem.

10-1998-0048064 discloses a parking alarm system. When the vehicle is parked after the vehicle is parked, the parking alarm device senses front and rear objects located close to the vehicle, Thereby displaying a distance to an object and outputting an alarm sound so that safe parking can be performed.

However, such a device is a sensor installed in a vehicle, and thus can not detect a collision of a side wall of the vehicle with a wall in a section such as a curved ramp of a parking entrance / exit road, which is not very helpful. Therefore, there is a growing need for a technique capable of preventing collision between the front and rear sides of the vehicle as well as the side surfaces in the same section as the curved ramp of the car entering and leaving the parking lot.

FIG. 2 is a view illustrating an apparatus and method for inducing a parking lot safety distance according to an embodiment of the present invention.

The parking lot safety distance guiding apparatus according to the embodiment of the present invention includes at least one or more beacons 200 installed in a parking lot entrance and exit road and a parking area, At least one distance detection sensor 300 attached to the terminal 400, the parking entrance / exit road and the wall surface of the parking area and acquiring distance information to a passing vehicle, and a vehicle approaching the limit distance or less from the parking lot wall surface And a parking lot server 100 that transmits a warning message to a mobile terminal 400 of a user who is on a vehicle approaching a limit distance or less through the beacon 200. [

The beacon 200 is a short range wireless communication device that periodically exchanges information based on Bluetooth technology within a certain radius range (several tens of meters) around the mobile terminal 400. In particular, the mobile terminal 400 includes a beacon 200, It is possible to grasp the position of the user in the room. The beacon 200 may use Bluetooth low energy (BLE) to identify the location of the mobile terminal 400 and exchange information with each of the mobile terminals 400, It is possible to automatically detect the location of the user and provide related services.

In the present invention, the beacon 200 exchanges various information through the Bluetooth communication with each user's mobile terminal 400, and allows the user's mobile terminal 400 to specify its own location.

The distance sensor 300 is a sensor attached to a curved surface ramp and a wall surface of a parking space entering and exiting the parking lot. The distance sensor 300 acquires distance information from the position where the distance sensor 300 is attached to the vehicle passing by using ultrasonic waves or infrared rays Role. The distance information to the obtained vehicle is transmitted to the parking lot server 100 through wired / wireless communication.

2, the beacon 200 and the distance sensing sensor 300 are shown to be attached to different places as different components, respectively, but the distance sensing sensor 300 can be implemented to be included in the beacon 200 . That is, the distance detection sensor 300 can be incorporated in the beacon 200. In this case, distance information to the vehicle measured through the distance sensor 300 may be transmitted to the parking lot server 100 via the local wireless communication network of the beacon 200.

In the case of integrating the beacon 200 and the distance sensor 300, installation is simple and it is not necessary to install a wired communication network, so that the installation cost and the maintenance cost can be reduced.

The mobile terminal 400 is a portable terminal device possessed by each user and can be implemented as a smart phone or a tablet computer performing mobile communication, Wi-Fi communication, Bluetooth communication, and the like.

The mobile terminal 400 communicates with the beacon 200 through the Bluetooth communication, acquires location information of the user based on the signals exchanged with the beacons 200, 100). Meanwhile, the acquired location information of the user may be transmitted to the parking lot server 100 via the beacon 200.

The mobile terminal 400 communicates with the parking lot server 100. When the vehicle on which the user who owns the mobile terminal 400 approaches the limited distance or less from the wall surface of the parking lot, . At this time, the mobile terminal 400 may directly receive the warning message from the parking lot server 100 or may receive the warning message via the beacon 200. [

Such a warning message includes a video or voice warning of the possibility of collision with the parking lot wall surface, and may include an image or voice for determining and directing the steering direction of the vehicle handle so that the vehicle does not hit the parking lot wall surface. In addition, the warning message may include an image indicating in real time the distance between the vehicle and the parking lot wall surface in addition to the image or voice indicating the possibility of collision with the parking lot wall surface or the steering direction of the vehicle handle. For example, the user's mobile terminal 400 may output a warning message on the screen, which is implemented as an image showing the distance from the vehicle on which the user is boarding to the wall of the parking lot in real time. The user can grasp the distance from the vehicle to the wall surface of the parking lot through the screen of the mobile terminal 400 and prevent a collision between the vehicle and the wall surface of the parking lot by operating the steering wheel when the vehicle is too close to the wall surface of the parking lot.

3 is a block diagram showing a parking lot server in the parking lot safety distance guiding apparatus according to the embodiment of the present invention.

3, the parking lot server 100 includes a location receiving unit 110, a distance recognizing unit 120, a vehicle extracting unit 130, and an alarm transmitting unit 140, and further includes a user database 150, And a location database 160, as shown in FIG.

The location receiver 110 receives location information of each user from the mobile terminal 400 of each user.

As described above, the mobile terminal 400 of each user obtains the location information of the user through the Bluetooth communication with the beacon 200, and the acquired location information is transmitted to the parking lot server 100. At this time, the mobile terminal 400 may directly transmit the location information of the user to the parking lot server 100 through mobile communication or Wi-Fi communication. However, when the beacon 200 transmits the location information of the user to the beacon 200, And may transmit the information to the parking lot server 100.

The distance recognizing unit 120 receives the distance information from the distance sensor 300 to the vehicle on which each user is boarding, and determines whether the received distance information is less than or equal to the limit distance. The distance sensor 300 may transmit the distance information to the parking lot server 100 through the wired / wireless communication network. When the distance sensor 300 is integrated into the beacon 200, To the car server (100).

The vehicle extracting unit 130 analyzes location information of each user and extracts a mobile terminal of a user who has boarded the vehicle whose distance information is less than the limit distance.

The parking lot server 100 receives location information of each user from the mobile terminal 400 and receives distance information from each distance detection sensor 300 to each vehicle. However, in order to transmit the warning information to the mobile terminal 400 of the user who boarded the vehicle whose distance information is within the limit distance, The position information of the user and the distance information measured by the distance detection sensor 300 should be compared with each other to distinguish the mobile terminals of the user who boarded the vehicle.

For this purpose, the vehicle extracting unit 130 not only extracts the mobile terminal 400 of the user who boarded the vehicle by analyzing the location information of each user, but also extracts the distance measured by the distance sensor 300 It is possible to extract the mobile terminal 400 of the user who boarded the vehicle whose information is less than the limit distance.

The warning transmission unit 140 may generate a warning message warning of the possibility of collision with the parking lot wall surface, and may transmit the generated warning message to the user's mobile terminal. At this time, the warning message may be directly transmitted from the parking lot server 100 to the mobile terminal 400 or may be transmitted via the beacon 200.

On the other hand, the warning transmission unit 140 extracts the closest distance from the vehicle to each distance detection sensor for each vehicle, and calculates the closest distance extracted for each vehicle to the mobile terminal 400 of the user who boarded the vehicle. In real time. In this case, the user aboard the vehicle can continuously grasp, in real time, the distance to the wall of the parking lot through the vehicle 400 through the mobile terminal 400.

The warning transmitting unit 140 may analyze the running direction of the vehicle, and may transmit a video or voice to each user's mobile terminal to determine and direct the steering direction of the vehicle handle so that the vehicle does not collide with the parking lot wall surface. The alarm transmission unit 140 of the parking lot server 100 can determine the driving direction through the change of the positional information of the vehicle on which each user is boarding. Based on the distance information from the vehicle to the wall, And thus determine which direction the steering wheel should be turned to avoid collisions.

For example, when the vehicle is moving in a counterclockwise direction to the upper floor and the left driver's door of the vehicle is too close to the wall, the warning transmission unit 140 transmits a steering handle to prevent the vehicle from colliding with the wall It is possible to transmit a warning message to the mobile terminal 400 of the user aboard the vehicle in a clockwise direction.

The user database 150 is a database storing information on personal information of each user and the location database 160 includes a map of the parking lot, a position of each wall surface, an installation location of the beacon 200, Is stored in the database.

The vehicle extracting unit 130 and the warning transmitting unit 140 calculate the position of each vehicle in the parking lot by referring to the location information of the user received from the location database 160 and the mobile terminal 400, It is possible to determine whether or not each vehicle is likely to collide with the wall surface of the parking lot.

FIG. 4 is a block diagram illustrating a mobile terminal of a user in a parking safety distance guiding apparatus according to an embodiment of the present invention. Referring to FIG.

4, the user's mobile terminal 400 includes a Bluetooth communication unit 410, a position obtaining unit 420, a warning output unit 430, a distance output unit 440, and a steering instruction unit 450.

The Bluetooth communication unit 410 is a component that performs Bluetooth communication with the beacon 200. The mobile terminal 400 performs mobile communication and Wi-Fi communication in addition to the Bluetooth communication. The wireless communication unit (not shown) performing the mobile communication and Wi-Fi communication is naturally implemented in the mobile terminal 400, The detailed description will be omitted.

 The location acquiring unit 420 can determine the location of the user in the room through the Bluetooth communication with the beacon 200 and the wireless communication with the parking lot server 100. [

The location acquisition unit 420 of the mobile terminal can acquire the location information of the user's parking lot by analyzing and calculating the beacon signal received from the plurality of beacons and the map of the parking lot. In this case, the map information of the parking lot is included in the mobile terminal in advance.

On the other hand, the location information of the user may be acquired in the following manner. When the position obtaining unit 420 transmits signals received from the beacon 200 to the parking lot server 100, the parking lot server 100 refers to the beacon signal received from the mobile terminal 400 and the location database 160 Generates position information of the user by calculating the position of the user, and transmits the generated position information to the position obtaining unit 420 of the mobile terminal 400. Through the above process, the location obtaining unit 420 can obtain the location information of the user in the parking lot.

The warning output unit 430 outputs a warning message received from the parking lot server 100 through a screen and a speaker.

As described above, the warning message includes a video or voice warning of the possibility of collision with the parking lot wall surface, and may include an image or voice to determine and direct the steering direction of the vehicle handle so that the vehicle does not collide with the parking lot wall surface. The warning message may further include an image indicating the closest distance from the distance to the vehicle and each distance detection sensor.

The image or voice for determining and directing the steering direction of the vehicle handle so that the vehicle does not collide against the wall surface of the parking lot is output to the screen or speaker by the steering instruction unit 450 and the closest distance The image to be displayed can be output to the screen by the distance output unit 440.

Hereinafter, a method for deriving a parking distance according to an embodiment of the present invention will be described. The method for deriving the parking lot safety distance according to the embodiment of the present invention is essentially the same as the parking lot safety distance guiding device according to the embodiment of the present invention and is omitted since it is essentially the same invention. Although only one user's mobile terminal 400 is shown in FIGS. 2 and 5 and only one beacon 200 and distance sensor 300 are shown in FIGS. 3 through 5, It is natural that it can exist.

FIG. 5 is a flowchart illustrating a method for deriving a parking lot safety distance according to an embodiment of the present invention.

First, the user's mobile terminal 400 receives a beacon signal from a plurality of beacons 200 (S110).

The mobile terminal 400 obtains the location information of the user based on the received beacon signal (S120). Although the mobile terminal 400 may calculate and acquire the location information of the user, the beacon signal received by the mobile terminal 400 may be transmitted to the parking lot server 100 as described above, And transmits the information to the mobile terminal 400 so that the mobile terminal 400 finally obtains the location information of the user.

When the mobile terminal 400 calculates and acquires location information of the user, the mobile terminal 400 transmits the location information of the user to the parking lot server 100. Of course, when the parking lot server 100 calculates the location information of the user, step S130 is omitted.

Meanwhile, at the same time as the above process, the distance sensor 300 measures the distance from the attached location to the vehicle to acquire distance information (S140), and transmits the obtained distance information to the parking lot server 100 (S150).

The parking lot server 100 analyzes the location information of each user (S160), extracts the mobile terminal of the user who boarded the vehicle (S170), and extracts the mobile terminal boarding the vehicle whose distance information is less than the limit distance S180).

Then, the parking lot server 100 transmits a warning message to the mobile terminal 400 that has boarded the vehicle whose distance information is less than the limit distance (S190).

On the other hand, as described above, the warning message may include an image or voice warning the possibility of collision with the parking lot wall surface, and may further include an image indicating the closest distance from the distance to the vehicle and each distance detection sensor. The mobile terminal 400 receives the distance between the vehicle and the distance detection sensor from the parking lot server 100 in real time and outputs the distance to the screen.

In addition, the warning message may further include an image or voice to determine and direct the steering direction of the vehicle handle so that the vehicle does not collide with the parking lot wall surface. In this case, the parking lot server 100 transmits the steering instruction message, which is a video or voice, to the mobile terminal 400 by determining the steering direction of the vehicle handle (S200), and the mobile terminal 400 transmits the received steering direction message Through a screen or a speaker.
