1 is a conceptual diagram of an indoor parking vehicle parking location determining system according to the present invention.

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

The vehicle communication unit 210 is installed in the plurality of vehicles 200. Recently manufactured vehicles often have a built-in Bluetooth communication device, and this Bluetooth communication device may be used as the vehicle communication unit 210. Any short-range communication device may be used as the vehicle communication unit 210 of the present invention as long as it is a short-range communication device embedded in a vehicle in addition to the Bluetooth communication device.

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

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

The access point 100 is connected to the server 400 by wire or wireless, and may transmit and receive data.

When the vehicle 200 or the user terminal 300 moves, when entering the communication 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 is performed. If outside of the available area, the wireless communication connection with the access point 100 is disconnected.

In the indoor parking lot vehicle parking positioning system according to the present invention, a plurality of access points 100 are installed on the ceiling of a point having a plurality of vehicle passages, and the plurality of directional antennas of the access points are each a vehicle passage in a different direction. In order to enable wireless communication in the direction of, it is possible to determine the moving path of the vehicle to be parked.

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

There are several ways to recognize when you park.

For example, it is a method of recognizing the moment when the attempt of the vehicle is turned off as the moment of parking. Alternatively, the vehicle 200 may recognize the moment when the short-range communication connection between the user terminal 300 carried by the driver is lost as the parking moment. Since a method of recognizing a parking moment is known in various ways, a detailed description thereof will be omitted.

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

An access point 102 having two directional antennas is installed at the ceiling of the entrance I of the indoor parking lot, so that the presence and movement direction of the vehicle to be entered and known can be known.

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

In FIG. 2, an access point is installed at the ceiling of a point having three vehicle passages and a point having four vehicle passages, and the plurality of directional antennas of the access point can wirelessly communicate in directions of vehicle passages in different directions, respectively. I'm heading to. Therefore, when the vehicle 200 and the user terminal 300 know the history of wireless connection with the access point, and know the moment of parking, the parking position can be estimated.

The figure displayed next to the circle among the access points shown in FIG. 2 means a directional antenna, and the direction to which the figure is attached indicates the direction that the directional antenna is facing. The direction that the directional antenna faces is that of the vehicle passageway.

For example, access points 102, 103, 104, 105 at a point with four vehicle passageways have four directional antennas, and access points 106, 107 at a point with three vehicle passageways have three It has a directional antenna.

Each directional antenna has its own communicable area. For example, the access point 104 has four directional antennas directional antennas 104a, 104b, 104c, 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 of FIG. 2, it will be detected that it has 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 that is directed after passing through the access point 104 will be detected to have moved in the direction that is toward the access point 105. And access point 105 will be detected as not passing.

According to the detection result, it can be estimated that the vehicle is parked in the P1 region. At this time, it is unknown to which of the six parking spaces in the P1 area.

In the embodiment of FIG. 2, reducing the number of access points increases the range of the estimated parking area, but has the advantage of reducing the cost.

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

FIG. 3 reduces the number of intersections (points having three or more vehicle passages) in which the access point is installed in FIG. 2.

In FIG. 2, the intersections adjacent to the intersections where the access points are installed are installed in such a manner that the access points are not installed, thereby reducing the number of installed access points by half.

In FIG. 3, if the vehicle passes the access point 111 in the direction of the arrow and then does not pass through the access point 112, it may be estimated that the vehicle parked in the P2 region. At this time, since it is unknown to which of the 12 parking spots in the P2 area, the range of the estimated parking area becomes wider.

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

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

FIG. 4 adds a number of access points with two directional antennas between the access points at intersections (points with three or more vehicle passageways) in FIG. 2.

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

In the case of FIG. 4, the cost increases due to an increase in the number of access points installed than in the case of FIG. 2, but has an advantage of more accurately estimating a parked position.
