JPS62279727A - Arrival communication system for vehicle - Google Patents

Abstract

PURPOSE:To surely inform arrival of a vehicle by receiving a weak radio wave representing an optional code sent from a vehicle by a transmission/reception equipment at a prescribed location, detecting a set code signal and displaying the approach of the vehicle and the talking enable state. CONSTITUTION:In calling a taxi by a house 6 whose code is 1035, a taxi 1 arriving in the vicinity of the house 6 by a command of an branch office to an idle taxi sends a signal of code 1035 from a transmission/reception circuit 3 via an antenna 5. The signal is received from an antenna 7 via a transmission/ reception circuit 8 at the house 6 and the lighting of the lamp of a display device 9 informs the arrival of the taxi 1. The talking enable state with the taxi 1 is recognized by the operation of the device 9 and a handset 10 makes a suggestion of the location of the house 6 for the taxi 1 through communication.

Description

[Detailed Description of the Invention] 3. 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, truck, etc. The present invention relates to a vehicle arrival communication method that uses weak radio waves to notify only the designated location of the vehicle, and also communicates between the vehicle and the designated location.

[Technical Background of the Invention] When a taxi is requested to pick up or drop off by telephone, the taxi may wait at the front door of the client's house or at a nearby location, or may sound 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 wait by flashing lights or pay attention to the sound of horns when the required travel time is approaching. There is. At the same time, if a taxi is called in the neighboring neighborhood, there is a drawback that it is difficult to tell which car has arrived at the request of the client.
Even when delivering or transporting goods by car, there are inconveniences such as having to worry about the arrival time or the sound of the car's exhaust or horn, making it difficult to accurately notify the arrival of the vehicle. requested.

[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 by 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/receiver mounted on the vehicle, and a fixed transmitter/receiver installed at a predetermined location transmits a weak radio wave into the atmosphere. The system detects the received and preset code number signal, and uses the detection signal to notify via the display device that a vehicle is approaching and that communication is possible between the vehicle's handset and the handset at a predetermined location. It is characterized by displaying.

[Example 1] The present invention will be explained below by taking a taxi arrival communication method as an example.A taxi 1 has an operation switch 2 for indicating a code number, which is composed of a ten-key keyboard from 0 to 9, etc. A transmitting/receiving circuit 3, a handset 4, which transmits and receives the code number specified by the operation switch 3 on a weak FM modulated wave with a range of 200 to 300 m, for example, by frequency shift telegraphy (FSK). Then, attach antenna 5. The operation switch 2 may be incorporated into the handset 4. The antenna 5 may be a common radio reception antenna or a wireless antenna for communication with a business office or the like.

Each house 6 that uses a taxi sets an appropriate area,
A predetermined code number is assigned to each house in the area.The house 6 is equipped with a transmitter/receiver circuit 8 that transmits and receives weak radio waves via an antenna 7, and this transmitter/receiver circuit 8 only receives signals with the code number. The transmitting/receiving circuit 8, which is set in advance to receive the signal, is provided with a display device 9 consisting of a buzzer circuit or a lamp lighting circuit, etc., and a handset 10 to indicate that the signal of the corresponding code number has been received. Note that the antenna 7 may also be used for television reception.

Now, if you call a taxi at house 6 with code number 1035, the taxi office will instruct a nearby vacant taxi to go to the house by radio or from the taxi office. When the taxi 1 arrives near the house 6, it specifies the code number 1035 using the numeric keypad of the operation switch 2. As a result, a signal with code number 1035 is transmitted from the transmitting/receiving circuit 3 via the antenna 5, and at the corresponding house 6, it is received from the antenna 7 via the transmitting/receiving circuit 8, and the display device 9 displays a buzzer sound or lights up a lamp to notify the taxi. -1 has arrived.

At home 6, the operation of the display device 9 indicates that it is now possible to talk to the driver of the taxi 1, so the transmitter/receiver 10
All you have to do is pick up the phone, talk to the driver of Taxi 1, tell him where you are, and tell him how many minutes you will be there.

[Effects of the Invention] As described above, the present invention can reliably notify only the relevant location that a predetermined vehicle is approaching or arriving within a set range, and can also improve communication between the driver of the vehicle and the other party. Because I can make calls.

You can send messages such as inquiries and answers when you do not know the other party's home etc. This method uses weak radio waves to target a limited area, making the system itself smaller and cheaper, and can be implemented without the need for an application under the Radio Law. In addition, simultaneous communication between the vehicle side and a fixed location is possible by changing the respective frequencies.
