Abstract

PURPOSE:To quickly send a bit of information such as arrival time and taxi number, while the taxi is moving on the street to a caller who corresponds to a terminal station in the equipment such as a taxi, by providing a transmitter for data transmission which uses a weak radio wave to each terminal station connected to a base station by a cable to each mobile station. CONSTITUTION:When a request for a taxi service is given to a base station 1 through a communication network 2 from a user 3n of a terminal station 3, the base station 1 identifies a taxi 51 located closest to the requester among mobile stations 5 via an operation processing unit 4, gives a massage to the taxi 51 as a prescribed car arranging command via a radio communication equipment 6, the taxi 51 confirms the information and moves toward the user 3n. At this time, the number and the arrival time of the taxi are informed to the user 3n. On the other hand, as the taxi 51 approaches the user 3n, the taxi 51 sends the taxi name and taxi number to the user 3n by means of the transmitter 9 using a weak radio wave. The user 3n uses a transmitterreceiver 8 to receive said radio wave to confirm the number of the taxi 51 and informs back the taxi of its reception.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is directed to a plurality of mobile stations (for example, taxis) that are dispatched via radio, and which receive taxi dispatch information and send information to customers. From the taxi moving towards the destination, to the taxi to the customer! This invention relates to a notification device for notifying IJW, etc.

"Conventional technology" Conventionally, in wireless taxis, the base station and The multiple taxis that serve as the IJ station are equipped with a means of transmitting information such as dispatch using wireless communication equipment, and taxi users can contact the base station of the above taxi by telephone to request allocation. He had the means.

[y! However, in conventional wireless taxis,
There is no way to transmit any information from side to side to the user side; for example, the user requests a taxi ride by phone, and then calls the nearest taxi via wireless communication from the base station of the same taxi company. When the same taxi headed for a client, there was no means for the taxi to notify the client of its arrival.

[Means for Solving the Problems] The present invention is intended to improve the above-mentioned problems when calling a conventional taxi. A wireless communication means is formed from the base station to a plurality of mobile stations, and each mobile station is equipped with a transmitter for data transmission via weak radio waves to the transceiver installed in each terminal station. It is something that you have.

``Embodiment'' The present invention will be described below based on an embodiment shown in the figure. Reference numeral 1 denotes, for example, a base station for a wireless taxi, and the base station 1 is connected to a network such as a wired telephone. 2, a plurality of users 31, 32, 33, who correspond to the terminal station (telephone) 3, ~
3n are linked. Further, the base station 1 is provided with an arithmetic processing unit 4, and the input side of the arithmetic processing unit 4 is configured to receive information such as vehicle allocation requests from the terminal station 3. The base station 1 is also equipped with a wireless communication device 6 for transmitting the contents of this input information to a plurality of taxis 51, 52, to 50 corresponding to the mobile station 5.
Each is equipped with three radio stations (7).

On the other hand, a transmitter/receiver 8 is provided on the terminal station 3 side, and each of the taxis 51, 52, ~5n corresponds to the transmitter/receiver 8 and transmits a weak radio wave with an electric field strength below a predetermined value.
It has 9.

The transceiver 8 is provided with a simple display screen 81 as shown in FIG. 2, for example, so that the taxi name, taxi number, arrival, etc. can be confirmed.

"Operation" In the above-described configuration, when a taxi dispatch request is given from the usage platform 30 of the terminal station 3 to the base station 1 side through the communication network 2, the information of this dispatch request is calculated in the base station 1. The data is introduced into the processing device 4 and recorded as data. This data is sent to the mobile station 5 via the arithmetic processing unit 4 to identify a taxi that is close to the request request, and is given to the corresponding taxi 51 of the mobile station 5 via the radio communication device 6 as a predetermined dispatch command. The taxi 51 confirms this information and moves toward the user 3n. At this time, the same user 3n is informed of the taxi code number (taxi number), dispatch time, etc.

On the other hand, when the taxi 51 approaches the user 3n, the transmitter 9 using weak radio waves transmits a predetermined signal, such as the taxi name and taxi number, to the user i3n from the taxi 51. . Since this transmitted signal is a weak radio wave, the range of the radio wave is, for example, about 100 m, and when the taxi 51 comes to a position of about 100 m, this radio wave is transmitted by the transmitter/receiver 8 on the user 3n side. 41 is possible to receive, and the same taxi 51 is on the same transceiver 8 side.
Upon confirmation of the code number @ (taxi number), the arrival of taxi 51 is displayed on the display screen 81. Alternatively, output a notification sound. Furthermore, the taxi is notified of the fact that it has been received.

"Effects of the Invention" As described above, a plurality of terminal stations are connected to a base station by wire, a communication means is formed between the base station and a plurality of mobile stations by wireless communication, and each mobile station has the above-mentioned communication method. By attaching a transmitter for transmitting data using weak radio waves to the transmitter/receiver installed in each terminal station, for example, in a taxi, etc., the mobile station can communicate with the called party, which corresponds to the terminal station. It is possible to transmit information such as the arrival and taxi number of a speed 1b while moving from the corresponding taxi side, and especially when there are multiple taxis nearby, it is possible to tell which taxi has called. Taxi numbers and other information are communicated and displayed on the transceiver, making it easy to identify.

4. Drawing (7) l! ! FIG. 1 is a block diagram of a main part of a data transmission method showing an embodiment of the present invention, and FIG. 2 is a front view showing an example of a receiver on the terminal station side.

In the figure, 1 is a base station, 2 is a communication network, 3 is a terminal station, 4 is an arithmetic processing unit, 5 is a mobile station, 6 is a wireless communication device, 7 is a wireless communication device, 8 is a transceiver, and 9 is a transmitter. 31.32.30 is the user, 51.52.511 is the taxi, and 181 is the display screen.
