Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a vehicle arrival notification method for notifying the arrival of a taxi, bus, etc. This invention relates to a vehicle arrival notification method that notifies only a location of a vehicle's arrival.

[Technical Background of the Invention] When a taxi is requested to pick up or drop off by telephone, the taxi either waits at the front door of the client's house or at a nearby location, or sounds its horn to notify the driver of its arrival. methods such as getting out of the car and going to make contact. However, waiting on a narrow road not only obstructs traffic, but also requires clients to stand by flashlights and pay attention to the sound of horns when the required time is approaching the pre-announced time. There is. Moreover, if a taxi is called in the neighboring neighborhood at the same time, there is a drawback that it is difficult to know which car has arrived at the request of the client.

Furthermore, in the case of school buses, etc., it is necessary to stand and wait in a designated place at a designated time, but if the operation status changes significantly due to road conditions, it may be necessary to wait on the road for a considerable length of time. There is. Waiting for a car like this can be troublesome, such as having to worry about the arrival time or the sound of the car's exhaust or horn when delivering or transporting goods by car. is required to notify the arrival of

[Object of the Invention] An object of the present invention is to provide a system for communicating the arrival of various vehicles as described above using weak radio waves without increasing the size and cost of the system.

[Structure of the Invention] The vehicle arrival communication system of this invention transmits a weak radio wave representing an arbitrary code number into the atmosphere from a transmitter mounted on the vehicle, and receives it at a receiver installed at a predetermined location. The present invention is characterized in that the preset code number signal is detected, and the detection signal is used to display text on the television receiver indicating that the vehicle has arrived.

[Embodiment] The present invention will be described below with reference to the drawings, taking a taxi arrival communication system as an example.

There is an operation switch 2 for specifying a code number consisting of a ten-key keyboard from 0 to 9, and a code number specified by this operation switch 2 is transmitted to, for example, a frequency shift telegraph (F
A transmitter 3 that transmits on a weak FM modulated wave with a reach distance of 200 to 300 m by the method of SX) and an antenna 4 are attached. The antenna 4 may be a common radio reception antenna or a wireless antenna for communication with a business office or the like.

Each household 6 that uses a taxi sets an appropriate area and assigns a predetermined code number to each household within the area. 7 is set in advance to receive only the signal with the code number for that receiver. The receiver 7 is provided with a buzzer circuit 8 to notify by sound that the signal of the corresponding code number has been received. A television receiver 10 is connected to the receiver 7 via a character signal generating circuit 9 which outputs the taxi company name, vehicle number, and a character signal indicating that a taxi has arrived.

The character signal generation circuit 9 transmits the character signal to the television receiver 1.
0, and a character signal is projected onto the top or bottom of the CRT. To insert a character signal into the television receiver 10 which is receiving a broadcast signal, it is sufficient to use a technique widely known in the field of subtitles and character communication. is connected. This power-on circuit 11 is for turning on the television receiver 1O by an output signal when a signal of the corresponding code number is received, and is similar to a power switch in a remote control device of the television receiver 10. It is something.

Note that the antenna 5 may be used in common for television reception.

Therefore, if you call a taxi at home 6 whose code number is 1035, the taxi office will instruct a nearby vacant taxi to go to the home by radio or from the taxi office. Taxi 1, which arrived near House 6, entered the code number 1 using the numeric keypad of operation switch 2.
035. As a result, a signal with code number 1035 is transmitted from the transmitter 3 via the antenna 4, and at the corresponding home 6, the signal is received from the antenna 5 via the receiver 7, and the buzzer circuit 8 generates a buzzer sound. At the same time, the television receiver 10 displays text indicating that the taxi has arrived along with the taxi company name and vehicle number. As a result, even if you watch television until the taxi arrives, you will immediately know when the taxi has arrived. Further, even when the power of the television receiver 10 is off, the power of the television receiver 10 is turned on by the power-on circuit 11, and the arrival of the taxi 1 can be displayed in text. The buzzer circuit 8 can notify the user of the arrival of a taxi even when the user is not watching television.

If this method is applied to school buses, by assigning a common code number to all households in a given area, all households in that area can be notified of the arrival of a school bus at the same time. . In this case, there is no need to assign a different code number to each area, and a common code may be used for all households using the school bus.

[Effects of the Invention] As described above, the present invention is capable of reliably notifying only the relevant location by text information that a predetermined vehicle is approaching or arriving within a set range, and is capable of informing a limited narrow area. In order to target the target, weak radio waves are used, which allows the system itself to be miniaturized and provided at low cost, and can be implemented without the need for an application under the Radio Law.
