Abstract

(57) [Summary] [Problem] A parking lot can be easily and reliably secured even in a downtown area where the parking lot is likely to be full. According to the present invention, a GPS receiver is provided in a wireless base station, and is connected to an automatic ticketing machine of each parking lot by radio, so that empty and position information of each parking lot can be constantly managed. Even if there is a parking request, the nearest parking lot can be notified promptly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot guidance system that allows a user to easily find the nearest empty parking lot by using a portable terminal in a place such as a downtown area where parking is extremely small.

[0002]

2. Description of the Related Art Conventionally, if a car navigation system is installed in a car, it is possible to know the position, name, and parking fee of the nearest parking lot. Therefore, if the car is moved according to the instruction of the car navigation, it is possible to go to the nearest parking lot. Further, there is a display board of a parking lot in the downtown area, and even if a car is moved based on the display board, it is possible to go to the nearest parking lot.

[0003]

By moving the car in accordance with the car navigation or the display board, it is possible to go to the nearest parking lot. However, if you go to the parking lot and it is full, you have to wait until it is empty. Then, when in a hurry, the user goes to another parking lot, but the parking lot is not always empty.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and comprises a plurality of base stations which are respectively arranged at predetermined positions in a predetermined space to form respective radio areas, and which are carried by a user. In a parking lot guidance system for allowing the user to reach a target vacant parking lot from an arbitrary position in the predetermined space by data transmission / reception means between the base station and the mobile terminal,
Each of the plurality of base stations manages empty information and position information from an automatic ticketing machine that manages the number of empty vehicles in a parking lot, and has a means for transferring these information when requested by the portable terminal. Provide parking lot guidance system.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a parking lot guidance system of the present invention, FIG. 2 is a block diagram illustrating a configuration of the parking lot ticket issuing machine of FIG. 1, and FIG. 3 is a block diagram of a wireless terminal used in FIG. FIG. 4 is a block diagram of the radio base station used in FIG. 1, FIG. 5 is an explanatory diagram showing an example of the storage contents of the memory in FIG.
FIG. 7 is a flowchart illustrating the operation of the wireless base station used in FIG. 4, and FIG. 7 is a diagram illustrating a data sequence of the wireless terminal, the wireless base station, and the parking lot used in the parking lot guidance system of the present invention. .

In FIG. 1, reference numeral 1 denotes a radio base station, 2 denotes a radio terminal, and A to D denote parking lot ticket machines with a radio function in each of the parking lots A, B, C and D. In the parking lot ticketing machine of FIG. 2, reference numeral 30 denotes a wireless unit, and reference numeral 36 denotes an empty vehicle information management unit. In the radio unit 30, 37 is an antenna, 31 is a transmission circuit, 32 is a reception circuit, and 33 is DS
P and 34 are composed of a CPU and 35 is a memory. In FIG. 3, a radio terminal 2 includes a transmission circuit 12 for transmitting and receiving data to and from the radio base station 1, a reception circuit 14 for receiving data transmitted from the radio base station 1,
A DSP (Di) that performs processing for decoding data received by the receiving circuit 14 and encoding data to be transmitted.
digital Signal Processor) 18
And a CPU 20 for controlling each unit, an input unit 22 for inputting data, and a display 24 for displaying various data.
A memory 26, an audio CODEC (Coder Decoder) 28 for encoding and decoding an audio signal,
It has a speaker 30 for outputting sound and a microphone 32 for inputting sound.

[0007] In the wireless base station 1 of FIG. 4, the same members as those of FIG. 3 are given the same names, but the wireless base station 1 has an input unit 22, a display unit 24, Although it does not have the functions of the speaker 30 and the microphone 32, the speaker 30 and the microphone 32 are provided with the position detection unit 16. The position detection unit 16 is, for example, G
It consists of a PS receiver, receives radio waves from geostationary satellites,
The position information (latitude, longitude) indicating the current position of the parking lot managed by the own station is obtained. The position detection unit 16 is not limited to this,
You may comprise so that it may be implement | achieved by another position detection technique.

Next, the operation will be described with reference to FIGS. As shown in FIG. 2, a wireless unit 30 is installed in an automatic ticketing machine that manages the number of empty vehicles in a parking lot. The wireless unit 30 transmits empty vehicle information from an empty vehicle information management unit 36 to the wireless base station shown in FIG. In response to a request for empty vehicle information due to an incoming call, the current empty vehicle information is notified. Therefore, the wireless base station 1 obtains the empty vehicle information from the four parking lots A, B, C, and D shown in FIG. 1 and the position, name, telephone number, and parking fee of each parking lot as shown in FIG. Is always managed by registering the information in the memory.

Here, the user holding the wireless terminal 2 is shown in FIG.
When the vehicle arrives at the position as indicated by (1), a wireless connection is made as shown in FIG. 7 to make a parking lot guidance request to the wireless base station 1 (ST1). When the wireless connection is completed, the wireless terminal 2 transmits a parking lot guidance request command to the wireless base station 1 (ST2). The wireless base station 1 selects a parking lot A and a parking lot B, which are within walking distance from the position of the wireless terminal 2 requested to manage the empty and location information of each parking lot, and wirelessly connects them. Is performed (ST4). Parking lot A
Notifies the wireless terminal 2 of the position information of the empty vehicle and the parking lot via the wireless base station 1 (ST5, ST6). When the wireless base station 1 notifies the wireless terminal 2 of the information, the wireless base station 1 disconnects the line between the parking lot A and the wireless base station 1 (ST7).

The wireless base station 1 notifies the wireless terminal 2 of the empty vehicle and the position information of the parking lot to the wireless terminal 2 via the wireless base station 1 in the same manner as the above-mentioned parking lot A (ST8, ST9, ST1).
0). When the wireless base station 1 notifies the wireless terminal 2 of the information, the wireless base station 1 disconnects the line between the parking lot B and the wireless base station 1 (ST
11) Further, the line with the wireless terminal 2 is also disconnected (ST1).
2). The wireless terminal 2 can go to the nearest parking lot based on the information from these parking lots A and B.

[0011]

As described above, according to the present invention, even if you drive to a downtown area where the parking lot is likely to be full, if you call the nearest wireless base station from the wireless terminal, the wireless base station is managed by the wireless base station. Since the wireless terminal is notified of the empty and position information of the parking lot, the parking lot can be easily and reliably secured.
