Description

[Detailed description of the invention] This invention relates to a wireless taxi calling device.
In particular, the called area name is reproduced from the audio reproduction means to reduce the burden on the operator.

<Background of the invention> In the taxi industry, a system is in operation in which taxis are equipped with wireless transceivers and are able to route empty cars to a waiting area upon receiving a call from a business office.

To give an overview of this system, a sales office receives a call from a customer and inquires by radio to each taxi whether there are any vacant cars in the area including the area where the customer is waiting. When it is determined that there are no empty cars in this area, the sales office inquires whether there are empty cars in the area adjacent to the area. When it is determined that there are no empty cars in this area, it searches for empty cars in other adjacent areas.

In this way, the business office searches for an empty car in the area closest to where the customer is waiting, instructs the empty car where the customer is waiting, and then routes the customer.

If the regions are divided into A, B, C, D, E, F, and G as shown in Figure 1, with the sales office at the center, if a customer request comes from area A, the sales office will First, an inquiry is made as to whether or not there are empty cars in area A, and if there are no empty cars in area A, then area B is inquired, and if there are no empty cars in area B, area G is inquired. In this way, while searching for a vacant vehicle, the operator of the office has to call out the name of each area over and over again, which is a heavy burden.

<Purpose of the invention> This invention reproduces the region name from a voice reproduction means while searching for an empty car, so that the operator only needs to speak when instructing the empty car to the location specified by the customer after finding an empty car. The purpose of this project is to provide a taxi calling device with

〈Summary of the idea〉 In this idea, a push button is provided to play the name of each region.
The system is constructed so that once the push button is operated, areas adjacent to the first area can be automatically called in sequence until a response is received from an empty car.

Therefore, according to this invention, once the operator at the sales office presses the push button corresponding to the name of the area where the customer is waiting, the voice reproducing means will play the area name by sequentially shifting the area until a vacant car is found. The burden will be significantly reduced.

<Example of the invention> Fig. 2 shows an example of the invention. In this example, a case is shown in which an 8-track tape cartridge reproducing machine containing an endless tape is used as the audio reproducing means. That is, in the figure, 1 indicates this tape cartridge, 2 indicates a playback head, and 3 indicates a playback amplifier. The tape cartridge 1, the reproduction head 2, and the reproduction amplifier 3 constitute an audio reproduction means 4.

Reference numeral 5 indicates a high frequency transmitter/receiver that constitutes a transmitting means and a receiving means. This transmitter/receiver 5 has transmitter/receiver switches 6 and 7, and when the transmitter/receiver switches 6 and 7 are turned to the contact a side, it operates as a receiver.
When pushed to the contact b side, it operates as a transmitter. 8 represents an antenna, and 9 represents a speaker. Reference numeral 11 denotes a crystal oscillator, and when the transceiver 5 operates as a receiver, this crystal oscillator 11 is used as a local oscillator, and when it operates as a transmitter, it is used as a carrier wave oscillator.

Reference numeral 12 indicates a head position control means for setting a track to be traced by the reproduction head 2. The head position control means 12 determines which track to reproduce depending on which push button in the push button switch group 13 is operated. The push-button switch group 13 is composed of, for example, seven push-button switches S _A to S _G corresponding to the regions A to G explained in FIG. For example, if the push button S _A is pressed down, the playback head 2 is moved to a position where it is in contact with the first track _T1 shown in FIG. Also, when push button switch S _B is operated, playback head 2 is moved to the second position shown in Figure 3.
It is moved to a position facing track _T2 . In this way, by operating the push buttons C, D, E, F, and G, the playback head 2 moves to the third, fourth, fifth, sixth, and seventh tracks T ₃ , T ₄ , T ₅ , and T ₆ , respectively. , is moved to a position facing T ₇ . Since such a mechanism is conventionally well known, further detailed explanation will be omitted here.

On the other hand, by operating the push buttons S _A to S _G , a signal is input to the tape starting circuit 14 and the tape drive motor 15 is started. The tape drive motor 15 is a motor that drives a capstan. Therefore, by driving the tape drive motor 15, the tape is fed at a constant speed.

For example, if the push button S _A is operated, the reproduction head 2 reproduces the first track _T1 shown in FIG. In the first track _T1 , for example, a question asking whether there is a vacant car in area A, such as "Are there any vacant cars in area A?" is recorded at the beginning. In this example, the inquiry is recorded twice and reproduced twice each time.

The signal reproduced by the reproduction head 2 is amplified by the reproduction amplifier 3 and inputted to the transceiver 5 through the manual call changeover switch 16a. It is assumed that the call switching switch 16a is always in contact with the contact A side, and can be switched to the contact B side by manual operation as necessary, and when the hand is released, the switch 16a is automatically switched to the contact A side. A switch shall be used to return the screen. A microphone 17 is connected to the transmitter/receiver 5 when the contact point b is pushed down, so that the operator's voice can be transmitted.

Tape stop signal SP after first inquiry content
are recorded. Therefore, when the first inquiry is repeated twice and reproduced, the tape stop signal SP is reproduced. This tape stop signal is a signal with a frequency outside the audio band, and the signal is extracted by the bandpass converter 18 to give a tape stop command to the tape starting circuit 14. This tape stop command stops the tape and ends the inquiry to area A. The tape stop signal SP activates the timer 19 and maintains the tape stop state for a certain period of time.

At the same time, the timer 19 is activated by the transmission/reception switching control means 21.
While the tape is stopped, the transmitter/receiver switches 6 and 7 are turned to contact a side, and the transmitter/receiver 5 is controlled to the receiving state.

When the timer 19 measures a certain period of time, for example about 10 to 20 seconds, the timer 19 outputs a time-up signal and gives a start command to the tape start circuit 14.
At the same time, a control signal is given to the transmission/reception switching control means 21 to return it to the transmission state. The tape starting motor 15 is driven again by the starting command, transporting the tape, and starting the first
Play the second content of track T ₁ . The second content of the first track _T1 is a content inquiring about the existence of empty vehicles in area B adjacent to area A. If you send this content twice, a tape stop signal will be sent.
SP is played and the tape stops again. At the same time, the transmitter/receiver 5 is switched to the receiving state by the control means 21.

In this way, the voice reproducing means 4 issues an inquiry to each region while sequentially shifting the calling region.

On the other hand, for example, if an empty car exists in area A at the time when the inquiry to area A at the beginning is completed, a response signal from the empty car is received while the tape is stopped. If this response is received, the operator moves the manual call changeover switch 16a to contact b side,
A microphone 17 is connected to the transmitter/receiver 5, and the location where the customer is waiting is transmitted to the empty car through the microphone 17.

At this time, the manual call changeover switch 16a has a switch 16b interlocked therewith, and this switch 16b controls the initialization means 22 which returns the state of the audio reproduction means 4 to the initial state. This initialization means 22 can be constituted by a flip-flop, for example. When the manual switch 16b is pushed to the contact point b, the flip-flop becomes set, and the state of its output terminal Q is inverted to H logic. This H logic signal is applied to the tape starting circuit 14 to continue driving the tape. As shown in FIG. 3, the tape has a sensing foil 23 at the leading position as is well known.
is pasted. This sensing foil 23 is detected by a detection means 24. When the sensing foil 23 is detected by the detection means 24, the initialization means 22
The flip-flops constituting the tape start-up circuit 14 are reset, and the H logic signal that was being supplied to the tape starting circuit 14 becomes L.
The logic falls and stops the tape drive.

Therefore, when an empty car is found, the operator operates the manual call changeover switches 16a and 16b to head towards the empty car and tell the customer where to wait, and at the same time the voice reproduction means 4 is activated.
is returned to its initial state and ready for the next call.

In the above description, the case where the first track is played back has been explained, but it is easy to understand that the same operation occurs when other tracks are played back.

<Effects of the invention> As explained above, according to this invention, by simply pressing the buttons S _A to SG of the area corresponding to the place where the customer is waiting, the system will start from the area name and no empty car will be found in that area. In such cases, inquiries are automatically made to neighboring areas for vacant vehicles, greatly reducing the burden on operators at the sales office.

Furthermore, if an empty car is found and a call is made to instruct the empty car where it is located, the audio reproduction means 4 is automatically returned to its initial state. You can then immediately service the next customer. In this respect as well, the burden on the operator can be reduced, and the effect is significant in practical use.

In the above description, a case has been described in which a tape cartridge is used as the audio reproduction means 4, but the audio signal indicating each area name is sampled at predetermined time intervals, the sampled signal is A-D converted, and the digital signal is stored in the RAM. It is also possible to use an audio reproducing means which stores the audio in a semiconductor memory such as , and sequentially reads out the memory to reproduce the audio. When using an audio reproduction means using a semiconductor memory in this way, a program memory is provided to store data corresponding to each region name at a predetermined address and to store the order in which each region name is to be read. By operating push buttons S _A to S _G ,
The same operation as described above can be achieved by reading out the area corresponding to each of the push buttons S _A to S _G of this program memory, and reading out the memory that stores the audio data according to the address written in that area. I can make you do it.

In addition, in the above example, the timer 19 is provided to automatically start the tape and return to the sending state after a certain period of time after the tape stops. This may be done using a push button switch.
