Abstract

PURPOSE:To attain drop-in communication simply with a small sized system without making application in compliance with the radio law by using a weak radio wave so as to send a command signal representing kinds of business, name of companies and a sender requiring drop-in within a narrow range. CONSTITUTION:In calling a taxi 6 from a house 1 whose sending code is 123, the house 1 operates a switch 5 to set a taxi company code 01, and a transmission/reception equipment 3 sends a business kind code signal and a sender code signal via an antenna 2. In receiving the signal by a transmission/ reception equipment 8 of the taxi 6a driving a district receiving the signal, the sender code number is displayed on a device 9, and in case of the pickup available, a switch 10 is operated to send an acknowledge signal to the sender. The acknowledge signal is received by the transmission/reception equipment 3 of the sender and is displayed by a buzzer sound or lamp illumination on a display device 4 for the acknowledgement of the taxi.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Industrial Field of Application] This invention relates to a stopover communication method for vehicles such as taxis traveling in a neighborhood or freight cars for collection and delivery. Specifically, the present invention relates to a drop-in contact method that uses weak radio waves to transmit an instruction signal indicating the name of the industry or company requesting a stop-in and the source of the call only in a narrow area.

[Technical Background of the Invention] When requesting a stop by a vehicle such as a taxi or a freight vehicle used for collection and delivery, contact the business office of the vehicle by telephone, and at the business office, the taxi radio (AVM) or transportation industry radio (M' C
According to A), a vehicle traveling near the location requested to stop by is summoned and instructed to go to the location. If this system is installed in each home or business, instructions can be given to the desired vehicle without going through a sales office, etc. However, since such radios are only authorized to make calls to the licensed person, Not only is a legal application required, but the transmitting and receiving equipment is also large and expensive.

[Objective of the Invention] The object of the present invention is to develop a method for notifying various vehicles of the above-mentioned stop by using weak radio waves without making the system large and expensive, and which is easy to operate. The purpose of the present invention is to provide a vehicle stopover communication method that can be implemented by.

[Structure of the Invention] In the vehicle stop contact system of the present invention, a first code number representing the industry or company name requesting a stop is set by an operation switch, and this first code number and a second code number representing the caller are set. The first code and second code number are repeatedly transmitted into the atmosphere from a fixed transmitter using weak radio waves. This system is characterized by displaying a 2-code number to confirm the sender.

[Embodiment] Hereinafter, an embodiment of the present invention shown in the drawings will be explained. In addition to assigning a different call code to each house or company in advance, each taxi company, cargo transporter, fishmonger, greengrocer, etc. An industry code different from the above-mentioned transmission code is set for each cleaning layer, and these codes are made up of a combination of a plurality of numbers. In other words, the industry code is composed of two digits, such as 01 for a taxi company and 02 for a cargo transport company, and a calling code is attached to each room in one turn, such as 101, 102, 103, etc. 6 Each house 1 is equipped with a weak FM radio with a range of 200 to 300 m.
A transceiver 3 transmits and receives modulated waves via an antenna 2, an operation switch 4 composed of, for example, a ten-key keyboard, for setting an industry call code to call a desired trader, and a confirmation signal is received by the transceiver 3. A display device 5 is provided for displaying a buzzer sound or a lamp. The transmitter/receiver 3 is set in advance so that it automatically transmits the call code of the user's home when the industry call code is sent, and is also configured to repeatedly send these signals. The antenna 2 may also be used in common for television reception.

Vehicles 6a and 6'b, such as taxis and cargo transport vehicles, are equipped with a transceiver 8 that receives only the relevant industry code signal via an antenna 7, a display device 9 that displays the code signal of the called party on, for example, a liquid crystal display, and a transmitter. In order to send a confirmation signal to the sender, it has an operation switch 10 having a setting switch, such as a ten-key keyboard, for setting the code number of the sender, and a push button for sending the confirmation signal. The transmitter/receiver 8 is.

It is set in advance so that when a confirmation signal is transmitted, the industry type transmission code is also automatically transmitted. If a mobile terminal for AVM or MCA radio is installed in the vehicle, the transmitter/receiver 8 may be configured to process data using a CPU built in the mobile terminal. The pushbutton may also be used as a setting switch, or may be set in advance so that a confirmation signal is automatically sent when a call code is set using the setting switch.

These transmission codes and confirmation signals may be carried by, for example, frequency shift telegraphy (FSK).

Now suppose that you call a taxi 6a at house 1 with calling code 123. At the house 1, the operating switch 5 is operated to set the taxi company code 01, and the transmitter/receiver 3 transmits the industry code signal and the source code signal into the atmosphere via the antenna 2. When a taxi 6a traveling in an area where this signal can be received receives it with its transmitter/receiver 8, the code number of the source 1 is displayed on the display device 9.

If it is possible to pick up the person, operate the operation switch 10 to send a confirmation signal to the caller. This confirmation signal is received by the transmitter/receiver 3 of the transmission source, and the display device 4 indicates that the taxi has been confirmed by a buzzer or by lighting a lamp. Empty taxi in area where radio wave reception is possible
Even if there is no caller, the transmitter/receiver 3 of the caller repeatedly sends out the calling signal until an empty taxi enters the area and sends out the confirmation signal.

If this vehicle drop-in contact system is to be implemented, each industry in each municipality will discuss and set a predetermined industry call code, as well as attach a call code for the company or home in each area that wishes to use this system. . Note that in places where it is impossible to determine from which area the outgoing signal is coming from because it is close to an adjacent area, a code number that is different from other outgoing call code numbers may be assigned.

[Effects of the Invention] As described above, the present invention targets a limited narrow area and instructs a vehicle of a desired type of business to stop at a company or home within the area. Therefore, weak radio waves can be used, and as a result, the system itself can be made smaller and
It can be provided at a low cost and can be implemented without any application under the Radio Law. At work or home, you only need to set the desired industry code, so operation is easy, and even if there are no vehicles of the desired industry in the area, the transceiver will repeatedly send out a signal asking you to stop by. , even if a vehicle of the desired industry subsequently enters the area.

You can definitely catch that information.
