Abstract

PURPOSE:To eliminate disease of a taxi and a user and to utilize a radio wave effectively by allowing each of reception stations to detect it that one of on- vehicle mobile stations accesses a relevant reception station as user information. CONSTITUTION:When a user desiring despatch of a taxi makes a request in wire communication and an on-vehicle mobile set (taxi) replying the call arrives in the vicinity of an object user, a stationary reception station installed in the said user's house receives selectively a radio wave sent from the taxi. The stationary radio base station has a provision of fetching a signal from a public line PSTN in addition to a transmitter and a receiver of its radio installation. That is, the stationary base station uses a network control section NCU connecting to the public line PSTN to await the reception of a phone call. When a call comes from the user, the sent signal passes through a decoder via a hybrid circuit HYB after the incoming call processing and is fetched by a control section CONT via a control bus or a CPU port.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radio communication system such as a taxi.

[0002]

2. Description of the Related Art Conventionally, a taxi user calls a taxi company and waits until a car arrives, except when picking up a taxi running on a highway. A taxi company received a phone call from a user, wirelessly called a car (taxi) running in the town, waited for an empty car to reply, and then directed the destination when there was a reply.
The taxi driver who receives the instruction of the destination will drive toward the destination.

[0003]

In recent years, there have been severe traffic congestions in towns, and it is often difficult to reach the destination. Also, depending on the time of day, it often happened that a vacant car could not be found easily and could not head to the user's house. In such a case, the user does not come to the car easily, so call the taxi company again and
I was nervous when I checked the arrangements, went out to check the arrival of the car, or listened to the sound of the car outside indoors. Especially in the case of customer business, when calling a taxi at the request of the customer, it often takes time to go out and check the arrival of the car so as not to be rude as part of the service to the customer, so it took a lot of manpower. .

In a taxi company, in response to an inquiry from a user, the inquiry is made to a car traveling by radio, and the answer is answered to the telephone user. For this reason, the number of radio calls is increased, and the driver has to respond to this during driving, which is a driving safety problem. Also, along with this, it was necessary to perform unnecessary radio wave transmission. In addition, other drivers who listened to this radio had to get close to their nerves each time, leading to fatigue. Under such circumstances, the driver used to inform the taxi head office by radio when he arrived at the destination to alleviate the anxiety of the head office by voice. This was also a factor in increasing wireless traffic. As with the above, other drivers who listened to this radio had to keep their nerves close to each other, which also led to fatigue.

Further, when a taxi driver arrives at a destination, a taxi driver sounds a horn without hesitating to disturb residents in the neighborhood, or gets out of the car to the house of the customer who called the taxi to directly drive the customer. Had to tell that he had arrived. Even when I was in a difficult parking situation, I had to be very careful about getting out of my car. Especially on a rainy day, fatigue was further increased, which was not preferable for safe driving. On the other hand, if the customer who called the taxi does not come out of the house immediately after arriving, the taxi must be parked at that place for a long time, and therefore the taxi that is parked is not available. It often obstructed traffic, disrupted traffic, and was naturally nervous for the driver. It is necessary to work under such bad working conditions, there are few applicants for taxi drivers,
It had developed into a problem of lack of employment.

[0006] Further, if the horn becomes a noisy town, and the horn at that time cannot be heard by the customer who called the taxi, the customer will not come out forever, causing a vicious circle such as ringing the horn.
From another point of view, taxi users looked for the taxi company's telephone number when arranging a car, or put it on the wall so as not to forget it, and spoiled the aesthetics of the room. Also, if the user does not find a phone number for a taxi company,
I would call another taxi company, and if I tried to use that taxi company, I would have missed some customers.

The object of the present invention is to eliminate such anxiety of taxi companies, alleviation of user anxiety, elimination of driver fatigue, realization of a quiet town, elimination of traffic congestion, effective use of radio waves and users from taxi companies. It is an object of the present invention to provide a mobile station approach notification system that can easily achieve the following.

[0008]

In order to achieve this object, a mobile station approach notification system according to the present invention is a vehicle-mounted mobile device which a taxi user dials a taxi company by wire and receives a response, that is, When the taxi arrives at the destination near the user's house, the fixed reception station installed in the user's home of the taxi selects and receives the signal from the on-vehicle mobile device, that is, the in-vehicle mobile device, that is, the taxi. It is configured so that taxi users can know when is approaching their destination.

[0009]

Embodiment An embodiment of the present invention will be described with reference to FIG. Figure 1
There is a fixed base station for taxi radios in the center, and it is possible to issue instructions to each car and to contact the fixed radio base station from the mobile station installed in each taxi. The large circle on the outside shows the area where the fixed base station radio station can service the mobile station installed in the taxi. It is called a large zone because the service area is large.
Three small circles are shown in the large zone circle, and this circle shows the range in which the user of the taxi can receive the radio waves emitted by the mobile station mounted in the car, that is, the taxi. Since the service area is small, it is called a small zone. Of course, it goes without saying that the radio waves emitted from the taxi reach the central fixed radio base station.

This service area is different in size from the fixed radio base station, which uses an ideal high-performance antenna with a height above ground and a high-power radio, while the antenna of a mobile station mounted in a taxi. This is because the ground clearance is low and not ideal, and the range of radio waves is not so wide because of low radio wave output. Moreover, the antenna of the user who receives the signal from this taxi and its ground clearance are not high performance. Therefore, the service area, or zone, of the radio waves emitted from the taxi is small when these two are combined.

Now, the devices and apparatuses and their operations will be described. FIG. 2 shows wireless equipment of a fixed wireless base station. The radio equipment of the fixed radio base station mainly consists of a high-performance antenna and a transmitter / receiver. A feature of the present invention is that the signal is taken in from the public line (PSTN) separately from the radio. The fixed base station normally located at the taxi head office is waiting for a telephone call at the network control unit NCU connected to the public line PSTN. Here, it is more convenient for the user to be configured to communicate with a coded signal instead of a voice. When there is a data notification from the user, after the incoming call processing operation, the transmitted signal passes through the hybrid circuit HYB and the decoder,
Further, the control unit CO is passed through the control bus or the CPU boat.
Captured by NT. Here, from the user "0002
Suppose a signal of 0000 0000 01 "is sent. The first 4 digits of" 0002 "are the user code of the sender and the next 4 digits of" 0000 "are to the taxi company,
The next four digits of "0000" are blocks allocated for data. The next 2 digits of "01" is the message code,
“01” is a code meaning reservation. An example of the code is shown in FIG. The control unit CONT separates the user number and the message number from the signals sent, and stores them in the storage unit ME.
The data is accumulated in the MO and displayed on the display unit. Here, the control unit CONT sounds the buzzer to notify the base station operator of the incoming call. Similarly, the control unit CONT automatically sends an acknowledgment code, for example, "04", to the user who sent the report, and automatically disconnects the telephone line. The control flow at this time is shown in FIG. After that, the base station operator manually operates the radio while watching these displays, and calls a taxi as usual.

As a further developed form, as shown in FIG. 2, the control unit CONT may send out the user number stored in the storage unit MEMO automatically to the taxi, together with the message code for operating the radio. When the taxi arrives at the destination and the arrival code such as "05" is sent from the taxi, the stored user number and message code may be deleted from the storage unit MEMO and the display unit. Similarly, when the user sends a cancellation signal of "02" over the public line, the radio is automatically activated to the taxi, the cancellation signal of "02" is sent, and even if it is subsequently deleted from the storage unit MEMO and the display. Good. The details will be described later.

FIG. 4 shows an example of the configuration of a user's radio equipment for receiving radio waves from a taxi, that is, a receiving station. Here, since it is not necessary to hear a voice signal from the taxi, a speaker is not provided. Also, since there is no need for transmission, a transmitter is not provided. It would be even more convenient to use wireless data transmission if a transmitter is provided and the number of the user sent from the taxi is received, and it is configured to reply that the user number has been received. Radio waves are transmitted in the immediate vicinity of the user's house, so they can be received strongly, there is little chance of encountering an error because the number of bits in the data is small, and because only the receiving equipment is required, it is possible to configure it inexpensively. I am doing it.

Characteristically, it is connected to the public line PSTN,
It is in the middle of sending out reservation signals. In order to request a car from a taxi company, the user _first turns on the power switch SW _{1 of the} device. As a result, the entire device is put into operation. Next, when the user presses the reservation switch SW ₂ , the control unit CONT reads the telephone number of the taxi company preset in the digital switch SW ₄ , and the network control unit NCU dials the taxi company. Controller CNOT the telephone a taxi company is connected sends a pre-pre-set user number to the digital switch SW ₅ destined taxi company (for example, "0002") and the reservation code (e.g. "01"). When a response signal (for example, "04") is obtained (automatically) from the taxi company,
The control unit turns on the lamp to display that the reservation has been made.
At this point, the receiving section is operated and the system waits for reception. The receiving unit may operate when turning on SW ₁ .

Conventionally, a taxi company was manually dialed, but now that it can be done automatically, dial operation mistakes are drastically reduced. Further, the user can dial even if he forgets the taxi company's telephone number, which greatly improves the convenience. In addition, even if you manually turn on the switch of the wireless receiver after dialing manually, the purpose is reached, but it is often forgotten when manually turning on the switch of the wireless receiver, so it is a convenient system. Will not be useful, either by operating the receiver in conjunction with after dialing is completed, or by making the receiver operate at the same time when dialing, it will prevent forgetting to switch on the receiver. , The system will work effectively. The operation flow at this time is shown in FIG.

Next, the situation when the taxi approaches the user's house will be described with reference to FIG. The signal received by the receiving equipment of the user's house is guided to the decoder for decoding the signal sent from the transmitter mounted in the taxi, and the decoded information is decoded by the control unit CONT. From the taxi, for example, "1234", "0002", "000"
It is assumed that 0 ”and“ 05 ”are sent. The code structure is composed of 14 bytes as shown in FIG. 6, and is composed, for example, of sender code + destination code + DATA code + message code. 6, the sender code is 4 bytes (1234), the destination code, that is, the user code (0002) is 4 bytes, the DATA code is 4 bytes (0000), and the message code is 2 bytes (0).
5), an example in which a total of 14 bytes are allocated is shown. For the sake of clarity, the synchronization signal and error correction are omitted. These may be added as needed.

These signals are signals such as FSK,
It may be a signal such as DTMF used in a wired telephone. In addition, if the sender is the same as the vehicle number in this figure, it is very convenient because the user who receives this vehicle number can immediately know which vehicle of the same taxi company when going out. As shown in FIG. 4, it is easy to display the received vehicle number as needed.

Here, the control unit CONT checks whether the received user number matches its own user number preset by the digital switch SW ₅ . When a match is detected, the message code is decoded, and in this case "05" is "arrival", the control unit CONT causes the lamp to blink or the buzzer to sound. Further, as an extended function, the transmitted caller code, that is, the vehicle number here may be displayed on the display unit. If a match with the user's own user number set in advance by the digital switch SW ₅ cannot be detected, the reception state is continued as it is. The user who hears the buzzer knows that the taxi has arrived, so the power switch SW
Cut ₁ Thus, the buzzer will stop ringing and you will be able to get out and immediately take a taxi. The operation flow at this time is shown in FIG. If the user who is waiting for reservation needs to cancel the reservation for some reason, (power switch SW
_{If 1} is turned on) and then SW ₃ is pressed, a cancel signal 02 can be sent to the taxi company in the same manner as above to cancel.
The taxi company can continue to cancel the taxi.

FIG. 8 shows wireless equipment installed in a taxi. In addition to the antenna and transmitter and receiver, this equipment is connected with a numeric keypad, such as a telephone, to generate a signal for transmitting the user number from the transmitter, so that the user's number (others) can be input. ing.
A taxi head office, that is, a radio base station, receives a request for a car by voice from a customer, that is, a user of a taxi (here, user b, for example), and wirelessly calls a vacant car by voice. It is assumed that the user b is registered with the taxi company and is given a code number of, for example, four digits, for example, “0002” in advance. When the car running in the area A that heard (received) this call, that is, the taxi, responds by voice, the wireless base station notifies the driver of the user name b and the code number "0002". The driver who hears this sets the user's number, for example, "0002", using a ten-key like a telephone.
In this case, the taxi does not send the number 0002 at this location, it just enters it in memory. After setting the user number, the car will head to district B.

When the driver arrives near the user's house in the B area, he pushes the switch SW ₀ of the apparatus. Then, the sender code “1234” and the user code “00” already set
02 ”, data code“ 0000 ”, message code“ 0 ”
5 "is transmitted by radio wave. This radio wave is emitted in the immediate vicinity of user b's house, so it can be reliably received at user b's house. The reception status at user b's house is as described above.

Apart from this, the taxi head office calls “0000”, “0” instead of voice as a call to the taxi.
Codes "000", "0002", and "01" may be sent. As often mentioned, this code configuration example has already been described.
0 is the head office code, the next "0000" does not specify a specific station but all taxi mobile stations, the next "0002" is the data code, in this case the user code, and the next "01". Indicates that there is an order from the user with the requirement code. All taxi mobile stations receiving this reply to the head office that they are empty. , "0
000 ”,“ 0000 ”,“ 06 ”is sent, which means that the“ 1234 ”vehicle is“ 0000 ”, that is, addressed to the head office,“ 0000 ”, that is, there is no data and is“ 06 ”, that is, an empty vehicle. The response from this car needs to be sent out as soon as it is difficult to see if the customer can get it, and it is efficient to send it out with one touch by pressing the switch SW ₁ shown in FIG. The head office responds to the responses from these taxis as "0000", "1234", "0002", "0".
When sending "1", the vehicle "1234" will send "000"
It means that the user has placed an order of 2 ". The operation flow of these is shown in FIG.

The mobile station receiving this signal is "0002".
The code is stored in the storage unit MEMO. This code number will be used to send you when you arrive near your home.
This saves the driver the trouble of manually inputting the user code. Further, when this code number is taken in, the control unit CONT searches for the code number, and if a program is made to display the address, name, and target on the display unit, the driver can immediately know the code number and the accompanying information. Very convenient.

In the above description, when the taxi approaches the user's house, when the taxi arrives, that is, when the "05" signal is transmitted, the same transmission power as that used for communication with the head office is used. Since it will be sent to the user's house from right before, 1/10, 1/100, 1 /
You may send it out even if it is squeezed to 1,000. Needless to say, this helps prevent interference.

[0024]

[Effects of the Invention] As described in detail above, in the past, when taxi users did not come to the requested car, they would call the taxi company again to check the status of car arrangements. Thanks to the invention, the arrival of a car can now be known in the indoor place where I am, so I can go outside and wait for the arrival of the car, or listen to the sound of the car
And it can be relieved. On the other hand, a taxi company responded to inquiries from users by wirelessly inquiring to the car that was running, and responded to the user on the phone by receiving the reply, but when arriving, a signal from the taxi arrives. So you can feel at ease. In addition, since information is exchanged by data, information can be exchanged in a shorter time than voice communication, and the amount of radio waves transmitted can be reduced, which can contribute to effective use of radio waves. In addition, since other drivers who intercept this radio do not have to go out of their nerves each time, it is possible to reduce fatigue and indirectly contribute to accident prevention.

When the taxi driver arrives at the destination, there is no need to ring the horn to notify the arrival, or to get out of the car and walk to the customer's house to notify the arrival. A quiet neighborhood can be achieved because the taxi user's neighborhood does not have to hear the taxi arrival horn. Moreover, getting out of this car and walking to the customer's house can be solved, especially on rainy days and on the upper and lower floors of the building. When a taxi arrives, the customer will come out of the house immediately, so the stop time will be shorter and the traffic in the neighborhood will not be confused. The effect of increasing is obtained.
Advantageous Effects of Invention According to the present invention, various taxis are freed from various troublesome operations, which is favorable to a driver, and a taxi company can easily hire a driver. For a taxi company, it is possible to secure fixed customers by contracting with taxi users, and furthermore, there is no fear of being called to other companies by forgetting the telephone number.
