Description

FIELD OF THE INVENTION [0001] The present invention relates to a system and method for detecting a parking position of an indoor parking lot,

The present invention relates to a parking position detection system and method for an indoor parking lot, and more particularly, to an indoor parking lot parking position detection system for detecting the position of a parking vehicle in an indoor parking lot using an access point having a plurality of directional antennas ≪ / RTI >

There is a case where the vehicle driver may not be able to memorize the parking position of the vehicle. Therefore, a technique of automatically storing the parking position of the vehicle and notifying the driver of the vehicle of the parking position when the driver approaches the parking position later is being developed.

The method of determining whether or not the vehicle is parked can be determined by determining that the vehicle is parked when the vibration of the vehicle is stopped or when the start of the vehicle is turned off or the wireless connection (e.g., Bluetooth communication connection) is disconnected, it is judged that it is parked.

Since the terminal of a recent vehicle or a driver of a vehicle (for example, a smart phone) has a built-in GPS position sensing device in many cases, it is necessary to use the GPS position sensing device to determine the parking position .

However, since it is difficult to determine the position by using the GPS position sensing device indoors, a separate position sensing means is required.

A number of techniques have been proposed for estimating the parking position by locating a plurality of access points in the room and determining the positions of the access points that are in wireless communication with the vehicle or the user's terminal.

Patent Documents 1 to 3 are examples of such techniques.

However, according to the invention described in Patent Documents 1 to 3, since a very large number of access points must be installed in order to enable a vehicle (or a user terminal) to perform wireless communication with an access point in all areas of a parking window, There is an increasing problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual diagram of a parking position detection system for an indoor parking lot according to the present invention; FIG.

 The access point 100 has a plurality of directional antennas, so that each directional antenna has a different communicable area.

A plurality of vehicles 200 are provided with a vehicle communication unit 210. In recent years, a vehicle manufactured in many cases has a built-in Bluetooth communication device. Such a Bluetooth communication device can be used as the vehicle communication unit 210. Any short range communication device that is built in a vehicle other than the Bluetooth communication device can be used as the vehicle communication portion 210 of the present invention.

The user terminal 300 is a communication terminal device carried by a vehicle driver, and a smartphone of a vehicle driver can also be used as a user terminal. However, in order for the smart phone to be used as the user terminal 300 of the present invention, an application program necessary for the smart phone should be installed.

The access point 100 can perform wireless communication with the communication terminal device in the communication enabled area and can perform wireless communication when the vehicle communication unit 210 or the user terminal 300 is located in the communication enabled area.

The access point 100 is connected to the server 400 via wired / wireless lines, and can exchange data.

When the mobile terminal 200 or the user terminal 300 moves into the communicable area of the directional antenna of the access point 100, wireless communication with the access point 100 becomes possible and communication of the directional antenna of the access point 100 The wireless communication connection with the access point 100 is disconnected.

In an indoor parking lot vehicle parking position identification system according to the present invention, a plurality of access points (100) are installed on a ceiling of a point having a plurality of vehicle passages, and a plurality of directional antennas of the access point So that the moving route of the vehicle to be parked can be grasped.

Knowing the moving path of the vehicle and the moment of parking, the parking position can be estimated.

There are many ways to recognize the moment you parked.

For example, it is a method of recognizing a moment when a vehicle is turned off as a parked moment. Or the instant when the local communication connection between the vehicle 200 and the user terminal 300 held by the driver is disconnected. Since various methods are known for recognizing the parking moment, detailed description is omitted.

2 is a first embodiment of an access point installation according to the present invention.

The access point 102 having two directional antennas is installed on the ceiling of the doorway I of the indoor parking lot, so that the presence and direction of the vehicle to /

For example, when a wireless communication connection is made with a directional antenna directed to the outside of the indoor parking lot, and then a wireless communication connection is made with a directional antenna directed toward the inside of the indoor parking lot, it can be determined that the vehicle moves inside the parking lot. On the contrary, when the wireless communication connection is made with the directional antenna directed toward the inside of the indoor parking lot, and the wireless communication connection is made with the directional antenna directed to the outside of the indoor parking lot, it can be judged that the vehicle moves to the outside of the parking lot.

In Fig. 2, an access point is installed on a ceiling of a point having three vehicle passages and four vehicle passages, and the plurality of directional antennas of the access point are capable of wireless communication in the direction of the vehicle passageways in different directions . Therefore, if the vehicle 200 and the user terminal 300 know the history of the wireless connection with the access point and know the moment of parking, the parking position can be estimated.

The figure shown next to the circle of the access point shown in Fig. 2 means a directional antenna, and the direction to which the figure is attached indicates the direction in which the directional antenna is pointing. The direction in which the directional antenna is directed is directed to the direction of the vehicle passage.

For example, an access point 102, 103, 104, 105 at a point having four vehicle passages has four directional antennas, and a point of access point 106, 107 having three vehicle passages has three Directional antenna.

Each directional antenna has its own communicable area. For example, the access point 104 has four directional antenna directional antennas 104a, 104b, 104c and 104d, the directional antenna 104a has a communicable area 104A, and the directional antenna 104b has a communicable area 104B.

If the vehicle has moved in the direction of the arrow in FIG. 2, it will be detected as having passed through the access point 101, the access point 101, the access point 102, the access point 103, and the access point 104. And the direction after passing through the access point 104 will be perceived as moving in the direction toward the access point 105. And the access point 105 will be detected as not having passed.

According to this detection result, it can be estimated that parking is performed in the P1 area. At this time, it is not known which of the six parking seats in the P1 area is parked.

In the embodiment of FIG. 2, if the number of access points is reduced, the range of the estimated parking area becomes larger, but there is an advantage that cost can be reduced.

3 is a second embodiment of an access point installation according to the present invention.

Fig. 3 shows a reduction in the number of intersections (points having three or more vehicle passages) at which the access points are installed in Fig.

In FIG. 2, the access points are installed in the intersection adjacent to the intersection where the access point is installed, so that the number of installed access points is reduced to about half.

In Fig. 3, if the vehicle has not passed through the access point 112 after passing the access point 111 in the direction of the arrow, it can be estimated that the vehicle has parked in the P2 area. At this time, since it is not known which of the 12 parking spaces in the P2 area, the parking range is estimated to be wider.

If it is desired to estimate the parking position more accurately than the embodiment in Fig. 2, it may further include an access point installed at the ceiling of the point having two vehicle passages.

4 is a third embodiment of an access point installation according to the present invention.

4, a plurality of access points with two directional antennas are added between the access points of the intersection (a point having three or more vehicle passages) in Fig.

For example, between the access point 121 and the access point 123, an access point 122 having two directional antennas is installed, and between the access point 124 and the access point 126, an access point 125 having two directional antennas is installed.

In the case of FIG. 4, there is an advantage that the parking position can be estimated more accurately, although the access point installed increases as compared with the case of FIG. 2 to increase the cost.

Hereinafter, a method of estimating the parking position using the access point and notifying the result to the vehicle driver will be described in detail, for example.

Therefore, when the vehicle 200 receives the information transmitted by the directional antennas through the vehicle communication unit 210, it is possible to estimate the parking position possible range. That is, when the vehicle 200 recognizes the moment it is parked, and then analyzes information received from the directional antennas until then, it is possible to estimate the parking position possible range. For example, in the example of FIG. 2, P1 can be estimated as a parking position possible range, and in the example of FIG. 3, P2 can be estimated as a parking position possible region.

When the vehicle estimates the parking position possible range, it can transmit the information to the user terminal 300. [

If the moment when the vehicle's attempt is turned off is recognized as a parked moment, the information can be transmitted to the user terminal 300 at a moment when the parking is sensed, information on the parking range estimated by the vehicle, or information received from the directional antennas .

 When recognizing the moment when the short distance communication connection between the vehicle 200 and the user terminal 300 held by the driver is terminated at the moment of parking, at a moment when the short distance communication connection is expected to be terminated, To the user terminal 300, the information received from the directional antennas.

The method for estimating the parking position availability range of the vehicle using the unique information received from the directional antenna of the vehicle is as described above, so a detailed description will be omitted.

If the parking position availability range is stored in the user terminal 300 by the above method and the owner of the user terminal 300 finds the parking position later, the user can see the parking position possible range displayed on the display unit of the user terminal 300 You can easily find your parking location.

When the owner of the user terminal 300 finds the parking position, the user terminal 300 can estimate the current position using the information received from the directional antennas, And the user can easily find the parking position easily.

The directional antenna periodically transmits different unique information, and the user terminal estimates and stores the parking position availability range of the vehicle using the unique information received from the directional antenna.

More specifically,

When the user terminal 300 receives the signal from the directional antenna and recognizes the parking moment, the parking position possible range of the vehicle is estimated and stored using the signal received from the directional antenna until the parking moment.

Information on whether or not the vehicle is turned on is information that can be used to determine whether or not the vehicle is parked. Therefore, information such as vehicle start-up information and short-range communication connection information received from the vehicle It may be called information related to whether or not parking is available. At this time, when the user terminal 300 receives the information on whether or not the vehicle 200 is parked, the user terminal 300 can determine the moment of parking.

 If the vehicle 200 can recognize the moment of parking, then the information received from the directional antennas may be analyzed to estimate the parking position possible range. For example, in the example of FIG. 2, P1 can be estimated as a parking position possible range, and in the example of FIG. 3, P2 can be estimated as a parking position possible region.

If the parking position availability range is stored in the user terminal 300 by the above method and the owner of the user terminal 300 finds the parking position later, the user can see the parking position possible range displayed on the display unit of the user terminal 300 You can easily find your parking location.

(Example 3)

A parking lot parking position determination system according to a third embodiment of the present invention includes a plurality of access points having a plurality of directional antennas, a plurality of vehicles, a plurality of user terminals, and a server capable of communicating with the access point.

The plurality of access points are installed on a ceiling of a point having three or more vehicle passages, and the plurality of directional antennas of the access point are each oriented to enable wireless communication in the direction of a vehicle passageway in the other direction.

The plurality of user terminals periodically transmit different unique information, and the plurality of directional antennas receive unique information of the user terminal and transmit the unique information to the server. The server estimates and stores the parking position availability range of the vehicle using the unique information received by the plurality of directional antennas. And then transmit the parking position availability range of the vehicle to the user terminal.

More specifically,

The plurality of user terminals periodically transmit different unique information, and periodically transmits a parking completion signal when it is determined that the vehicle is parked. Therefore, if the user terminal enters the communicable area of the communicable access point after completion of the parking, the user terminal can notify the server of the completion of parking through the access point. That is, the user terminal transmits information indicating that the vehicle is parked.

And estimates and stores the available parking range of the vehicle using the unique information received by the plurality of directional antennas before receiving the server parking completion signal. For example, in the example of FIG. 2, P1 can be estimated as a parking position possible range, and in the example of FIG. 3, P2 can be estimated as a parking position possible region.

Thereafter, the server can transmit the parking position availability range of the vehicle to the user terminal.

(Example 4)

A parking lot vehicle parking position determination system according to a fourth embodiment of the present invention includes a plurality of access points having a plurality of directional antennas, a plurality of vehicles, a plurality of user terminals, and a server capable of communicating with the access point.

The plurality of access points are installed on a ceiling of a point having three or more vehicle passages, and the plurality of directional antennas of the access point are each oriented to enable wireless communication in the direction of a vehicle passageway in the other direction.

The plurality of vehicles periodically transmit different unique information, and the server estimates and stores the parking position availability range of the vehicle using the unique information received by the plurality of directional antennas.

More specifically,

The plurality of vehicles periodically transmit different unique information, and the unique information is transmitted to the server through the access point. Therefore, if the server can know the parked moment, the parking position availability range of the vehicle can be estimated and stored using the information transmitted from the vehicle through the access point. For example, in the example of FIG. 2, P1 can be estimated as a parking position possible range, and in the example of FIG. 3, P2 can be estimated as a parking position possible region.

Examples of how the server learns parking moments include a method in which the user terminal learns through wireless communication with the vehicle (for example, a method of receiving a moment when the vehicle is turned off from the vehicle via wireless communication, ) And a method of recognizing the instant when the local communication connection of the user terminal 300 held by the driver is disconnected at the moment of parking). When the user terminal enters the communicable area of the communicable access point, And notifies the server of the completion of the parking through the access point. That is, the user terminal transmits information indicating that the vehicle is parked.

An example of a method for the server to find the parking moment is to estimate that the parking is performed when the antenna of the new access point receiving the signal generated from the vehicle does not exist for a predetermined time (for example, five minutes) or more. This is because when the vehicle continues to move, the antenna of the new access point will inform that it has received a signal from the vehicle, but since the vehicle is stationary after parking, the antenna of the new access point has little chance of transmitting signal reception.

Thereafter, the server can transmit the parking position availability range of the vehicle to the user terminal.

If the parking position availability range is stored in the user terminal 300 by the above method and the owner of the user terminal 300 finds the parking position later, the user can see the parking position possible range displayed on the display unit of the user terminal 300 You can easily find your parking location.

An indoor parking lot vehicle parking position determination method according to a fourth embodiment is an indoor parking vehicle parking method including a plurality of access points having a plurality of directional antennas, a plurality of vehicles, a plurality of user terminals, and a server capable of communicating with the access point Using a localization system, and includes the following steps.

(1) Step 1: The plurality of vehicles periodically transmit different unique information;

(2) Step 2: When the user terminal corresponding to the vehicle requests the parking position information, the server estimates the parking position possible range of the vehicle using the unique information received by the plurality of directional antennas To the user terminal

The plurality of access points are installed on a ceiling of a point having three or more vehicle passages, and the plurality of directional antennas of the access point are installed to face wireless communication in the direction of the vehicle passageways in the different directions.

The method may further include a third step of displaying a parking position availability range on the display unit of the user terminal when the owner of the user terminal searches for the parking position.

In the first to fourth embodiments, as shown in FIG. 2, the access point may further include an access point installed at the ceiling of the indoor parking lot entrance I.

In Embodiments 1 to 4, as shown in Fig. 4, it may further include a plurality of access points installed on a ceiling of a point having two vehicle passages and having two directional antennas.

In the first to fourth embodiments, it is possible to estimate the position using the DR sensor in a section where wireless communication with the access point is not performed.

In the first to fourth embodiments, the parking position availability range stored in the server is transmitted to the user terminal of the driver. In addition, the user terminal of the driver's family, (E.g., a family member of the driver, and other members of the group to which the driver belongs) can be used to find the parking position

Since the access points of the first and second embodiments generate signals in multiple directions, they can be called multi-directional beacons.

Since the access points of the third and fourth embodiments receive signals in multiple directions, they can be called multi-directional scanners.

In order to control entrance and exit at the access point at the gateway entrance, the parking lot vehicle parking position determination system of the indoor parking lot carries out a process of confirming whether or not the user terminal is the user terminal of the user permitted to enter and exit through communication between the user terminal and the access point , And the users who are permitted to access can be managed for each group. For example, in an apartment parking lot, an apartment member becomes a group, in a company parking lot, a company employee becomes a group, and in a parking lot of a medical institution, an employee, a patient, and a family become a group.

Therefore, if announcements or advertisement information are sent from the access point (or server) to the user's mobile terminal, appropriate notice information or advertisement information can be sent for each user.

The announcement information is information on notifications to be notified to the users of the group, and the advertisement information is information to be transmitted to the user for advertisement, and also includes information on coupon issuance and the like. Since the advertisement information can be transmitted for each group (that is, the advertisement information can be transmitted only to the user terminal of the user corresponding to the group), the advertisement effect is maximized and the new customer can be attracted.

Also, in Embodiments 1 to 4, since the location of the user terminal can be known by using the communication result of the access point and the user terminal (the DR sensor measurement value can be used where the access point and the user terminal are not in communication) The user terminal may display the parking position of the car and the route to the parking position. The application program installed in the user terminal (application program indicating the parking position of the car and the route to the parking position) is not activated and can be activated at the moment the communication connection between the user terminal and the access point is confirmed . That is, it can be turned on.

In the first embodiment and the second embodiment, the user terminal can be activated at the moment of receiving a signal from the access point.

In the third embodiment and the fourth embodiment, when the access point recognizes the user terminal, the information can be transmitted to the user terminal again to be activated.

It is possible for the user to guide the vehicle traveling route instead of the walking route after boarding the vehicle. An example of a method of recognizing a vehicle after boarding is a method of recognizing from a start of a vehicle, a method of recognizing a short-range wireless communication connection between a vehicle and a user terminal, and the like.
