Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a taxi calling device that connects a taxi waiting area and a base and is used to call a taxi from the waiting area. This invention relates to a taxi calling device.

0-) Prior art The present inventor divides the taxi driving area into multiple zones,
We have developed a device that transmits the actual empty taxis traveling in each zone to the base.

This device places a zone transmitter and a zone receiver in each zone, transmits actual empty vehicles between the vehicle transmitter phase mounted on the taxi and the vehicle receiver, and transmits the output of the zone receiver phase. It was sent to the base by wire, and empty vehicles in each zone were displayed at the base.

This device reduces the frequency and waveband of radio waves used,
In addition, in order to minimize antenna power and improve display reliability, dedicated wires must be used between the zone transmitter and zone receiver and the base. Normally, a dedicated telephone line is used for this wired line, but the dedicated telephone line is not used effectively enough just for transmitting empty taxis within the zone, and is essentially used to transmit signals. The disadvantage was that there were few times to do so.

■ Purpose The present invention uses the transmission lines of zone transmitters and receivers installed in various locations to detect waiting customers, thereby enabling customers to be detected within each zone without the need for special dedicated lines. An important object of the present invention is that the passenger's call signal and the actual vehicle or vacant vehicle signal can be effectively transmitted to the base via a dedicated line, and at the base, Since the empty car signal and passenger waiting signal for each zone are transmitted over the same line, it is easy to determine which taxi number is empty in the zone where the customer is hailing a car. By simply inserting a coin, information about the zone in which a passenger is waiting can be transmitted to the base.Furthermore, after inserting a coin, the passenger will be notified of the status of an empty taxi, so they can wait with peace of mind. It is on offer.

■ Configuration Embodiments of the present invention will be described below based on the drawings.

The taxi calling device shown in FIG. 1 includes a zone transmitter 1, a zone receiver 2, and a distributed sensor means 6 installed in each divided zone, and a car transmitting phase 3 and a car receiving phase 4 installed in the taxi. and a wired line 7 connecting the zone receiver 2, zone transmitter 1, and distributed sensor means 6 to the base, and a display for displaying empty cars and passenger calls that have entered each zone via this wired line. means 5.

One zone transmitter for each zone transmits zone radio waves within the zone where the zone transmitter is installed. For example, zone radio waves are emitted from zone A.A zone radio waves are transmitted with sufficient strength to be received by the reception phase 4 of a taxi that enters zone A, and when a taxi leaves zone A and enters zone B. At this time, the antenna power is determined so that the electric field strength at the boundary between the A zone and the B zone is reduced to a predetermined level or less.

Therefore, the effective antenna power and antenna directivity of each zone transmitter are determined by taking into account the size and shape of each zone, the antenna power of adjacent zone transmitters, the condition of obstacles, the reception sensitivity of the vehicle reception phase, etc. However, the width of the zone is, for example, several hundred meters.
In the case of a certain magnitude, it is generally determined to be several tens of microwatts to several tens of milliwatts, preferably several hundred microwatts to several milliwatts.

By the way, the paging device having this structure detects which zone the taxi has entered by checking which zone it enters. Therefore, the frequencies of the radio waves in each zone can be made completely the same. In addition, so that the taxi can receive the zone radio waves no matter when the taxi enters the zone, the zone radio waves are continuously transmitted unmodulated or with one signal F.
It is preferable to use M-modulated n or F2 type radio waves.

However, when placing a confirmation signal on this zone radio wave, when the zone receiver 2 receives the radio wave emitted from the taxi and the display means 5 confirms this, for example, the zone radio wave is FM-modulated with the taxi's vehicle signal. The signal is then transmitted for about 1 to 5 seconds, and the transmission of the vehicle transmission phase 3 is stopped by this modulated signal.

The vehicle receiving phase 4 includes a control circuit for the vehicle transmitting phase 3 that outputs an entry signal when a vehicle enters each zone, and the control circuit is configured to detect when the field strength of the zone radio wave exceeds a predetermined level when the vehicle leaves one zone. It will be reset when it reaches. Therefore, for example, the control circuit issues an entry signal when the vehicle enters the A zone, is reset when the vehicle leaves the A zone, and issues an entry signal when the vehicle enters the B zone again.

It is controlled by the control circuit of 3 double transmission phases, 4 car reception phases, and the actual empty state of the taximeter. That is, when a signal is issued to detect that a taxi has entered a certain zone, and when the actual empty state of the taximeter is changed, the control circuit sends a signal to the vehicle transmission phase 3, and the vehicle transmission phase is Transmitting car radio waves 3. The car radio waves include the taxi's vehicle signal and the vehicle signal so that it can be determined which taxi is transmitting the radio wave, the car that sent the radio wave, and whether the taxi hitting the taxi is an actual vehicle or an empty vehicle. The actual empty vehicle signal is FM modulated. For example, as shown in Table 1, the vehicle signal includes group signals of 10 channels with different frequencies;
Consisting of 10 channels of individual signals, 100 types of vehicle signals are created by combining the group signal and the individual signal, and the group signal and the individual signal are repeated at different times, for example, for about 1 to 5 seconds, to transmit FM to car radio waves. Modulate and transmit. When the taxi is empty, the empty car signal of, for example, H892, 5 Hz is FM modulated at the same time as the individual signal. The actual vacant vehicle signal may be transmitted on the car radio waves only when the vehicle is actually occupied or vacant, but it is also possible to modulate signals at different frequencies depending on when the vehicle is occupied and when the vehicle is vacant.

The transmission state of the vehicle transmission phase 3 is stopped by a timer or a confirmation signal from the zone transmitter 1.

The zone receiver 2 receives the car radio wave transmitted from the car transmission phase 3, performs FM detection on it, detects the vehicle signal, the yR1 table selection signal, the frequency table group signal, the individual signal, the actual vacant car signal, and displays it on the display means 5. send by wire.

The display means sFi sorts the signals sent from the zone reception image signal with an analog or digital bandpass filter, displays the vehicle that sent it and the actual empty vehicle status of that vehicle, and further displays the zone reception signal. It determines whether a signal has been sent from the aircraft and displays which lane the vehicle has entered.

The distributed sensor means 6 installed in each zone includes a coin slot 8, a coin storage box 9 communicating with the coin slot 8, and an insertion detection member for detecting that a coin is sent into the slot. and a response member.

The input detection member includes a microswitch 10 whose lever is disposed in the input passage of the fin, and this microswitch 10 is connected to an oscillation circuit 12 via a monostable multivibrator 11, as shown in FIG. It is connected to the. The monostable multi/(ibrator 11 shapes the trigger pulse of the microswitch 10 into a pulse with a constant width of, for example, 0.1 to several seconds, and uses this pulse signal to control the oscillation circuit 1.
2 corresponds to the pulse width, for example, 300H.
z's waiting signal is oscillated and transmitted to the display means 5.

The response member is for informing customers of the arrival of a taxi, and the response member shown in FIG. 2 includes two noquilot lamps 13, 14, a speaker 15, and two sets of band-pass filters 15, 16. ing.

The band pass filters 15 and 16 are Q type filters for selecting specific frequency signals sent from the base. For example, when a 3Q5H2 signal is sent from the base, the L-side no-pan, do-pass filter 15 detects this. Then, this signal is sent to the upper switching circuit 17, and the upper switching circuit 17 turns on the upper bi-four bit lamp 1:1 point ffi, illuminating the display on the front of the pilot lamp 13, that is, the display "Please wait 5 minutes". Inform customers.

Therefore, from the base, when making a customer wait for 5 minutes, 3058
Send the Z signal.

In FIG. 2, the lower bandpass filter 16 is 310H
2 signal is passed. Therefore, when a 310 Hz signal is sent from the base, the blocked pass filter 16 sends this signal to the switching circuit 18, and the switching circuit 18 emits a display saying "Please wait 10 minutes." Therefore, from the base, when making customers wait for 10 minutes,
Transmits a 1 GHz signal.

The speaker 14II'i is used to generate audio from the base, and generates an audio signal sent from the base, such as a signal such as "Please wait 00 minutes."

However, as shown by the chain line, it is also possible to provide a sound generation circuit 19 and control this sound generation circuit 19 with the output of the bandpass filter 15.16. The received audio signal, for example, "Please wait 5 minutes" or "Please wait 10 minutes", is stored in a memory such as a ROM, and this stored audio signal is used as the output signal of the bandpass filter 15.16. send to speaker.

When the output signal of the switching circuit 18 connected to the 310 Hz bandpass filter 16 is applied to the audio generating circuit 19, the audio generating circuit 19 sends a "Please wait 10 minutes" signal to the speaker 14, and the speaker 14 The output signal of the switching circuit 1T connected to the 305Hz bandpass filter 15 is called the audio generation circuit 1.
When the number 9 is added, the message "Please wait 5 minutes" is heard from the speaker.

The display means is installed at a base where the running conditions of all vehicles can be monitored. Therefore, the display means and the zone receiver are installed separately. The signal of the zone receiver is then electrically transmitted via the wired circuit 7 to the display means. This wired circuit 7Ka
, it is best to use the telephone line of the Japan Telecommunications Corporation.

Signals from a plurality of zone receivers 2 are sent to the display means 5, and it is determined from which zone receiver 2 the vehicle signal and the actual vacant vehicle signal are transmitted.

When the zone receiver 2 receives a signal emitted by a taxi and the signal is transmitted to the display means 5, the display means 5 displays a signal sent to the taxi that does not emit radio waves. It sends a confirmation signal to the taxi to let it know that it has been confirmed. The display means 5 therefore sends a confirmation signal to the zone transmitter 1.

The confirmation signal is, for example, a combination of the same group signal and individual signal as those transmitted by the taxi, and this confirmation signal is FM modulated into a 1 to 5 second zone radio wave and transmitted. Receiving phase 4 of the taxi that is transmitting,
The transmission of the car sending device 3 is stopped. Confirmation signals, like vehicle signals, are different for each vehicle. Therefore, each vehicle is equipped with a bandpass filter that selects only its own confirmation signal, and selects its own confirmation signal, for example, the same group signal and individual signal that it oscillates, and when it receives this confirmation signal. 1, stop the transmission of the car transmitter 3.

According to this method, even if two taxis transmit radio waves at the same time, the display of the taxi that emitted the radio waves will be completed first, and this vehicle transmission phase 3 will stop transmitting. After that, display processing for the next taxi can be performed.

The display means 5 includes a band pass filter 20 for sorting the waiting signal sent from the distributed sensor means 6, a switching circuit 21 that is turned on and off by the output signal of the band pass filter 2.0, and this switching circuit. The bandpass filter 20 is a bandpass filter that passes only the signal 300H2, which is the customer waiting signal, and the customer waiting signal passes through the bandpass filter 20. The switching circuit 21 is turned on, and the switching circuit 21 switches the customer bandpass filter 20, the switching circuit 21, and the customer waiting lamp 22 into MM for each zone so that the customer waiting lamp 22 can be displayed in each zone. When the number of wired lines and the number of distributed sensor means is less than the number of wired lines, a waiting lamp 22 is arranged above the vacant car display window 23 of each zone, corresponding to the number of distributed sensor means.

Furthermore, the display means 5 includes two pilot lamps 13 which are response members of the distributed sensor means 6 disposed in each zone.
．． Two sets of oscillator circuits 24 and 25 are provided for lighting or clearing 14. One side of the oscillation circuit 24.25 is 305H2.
One of the ponds oscillates a 31 GHz signal.

The oscillator circuits 24, 25 are connected to the wired line 7 via response switches 26, 27, 28 arranged below the empty vehicle display window 23 of each zone. Left response switch 26
is connected to the oscillation circuit 25 of 305 Hz, and the central response switch 2T is connected to the oscillation circuit 24 of 310H2. The response switch 28Fi on the right side is for transmitting an audio signal to the speaker 14 of the distributed sensor, and is connected to the microphone 30 via the amplifier 29.

The operation of the distributed sensor means 6 configured in this way is as follows: When a customer comes to the distributed sensor means 6 in the B zone and inserts a coin, the coin is inserted by the micro switch 1.
0, and the pulse signal from the microswitch 10 causes the oscillation circuit 12 of the distributed sensor to operate at 300Hz for a certain period of time.
A customer waiting signal is oscillated, and this signal is sent to the display means 5 through the wired line 7. Upon receiving this signal, the B zone band pass filter 20 detects a 300 Hz signal, and this signal lights up the 8 zone customer waiting lamp 22 to notify the base that there is a B zone customer waiting. . When the dispatcher at the base learned of this, he looked at the vacant car number in the B zone, informed the taxis that were vacant, and then turned on the response switch 26 or 27 in the B zone and sent the signal 305H2 or 310H2 to the wired line. 7 to the distributed sensor means 6 in the B zone, and one of the pilot lamps 13
, my father would turn on the 14 light to let customers know that a taxi would be dispatched in 5 or 10 minutes. At this time, after turning on the response switch 28 of the B zone connected to the microphone 30, call the microphone 30 "Please wait 10 minutes - 1" and utter this voice from the distributed sensor means speaker 14. It's also a good idea to let your customers know.

By the way, the zone transmitter 1 and the vehicle transmission phase 3 may emit radio waves at the same time. This is because zone transmitter 1 transmits continuously, so when car transmitter phase 3 transmits,
Both radio waves are transmitted at the same time.

Therefore, the frequencies of the two radio waves are separated at least to the extent that they can be selected by the receiving means so that the zone reception l1IA2 and the vehicle reception line 4 can select the two radio waves.

Furthermore, when modulating signals to the zone transmitter 1 and the vehicle transmission phase 3, FM modulation is better than AM modulation. This is because, unlike AM, FM can only receive the stronger one even if multiple radio waves are received at the same time, which has the effect of reducing malfunctions of the entire device.

The empty car number is displayed on the empty car display window of the display means 5. For example, if taxi α enters the A zone, the car reception line 4 detects this and the antibacterial circuit is activated. The vehicle transmitting phase 3 transmits a vehicle radio wave modulated by a vehicle signal and an actual vacant vehicle signal. This car radio wave is received by the zone receiver 2 of the A zone, and the zone receiver 2 transmits a signal to the display means 5 via the wired line 7, and the display means 5 displays that the taxi α has entered the A zone. After displaying the taxi number on the empty car display window 23 only when the taxi is empty, a confirmation signal is sent to the zone transmitter 3. When the zone transmitter 3 issues a confirmation signal, the vehicle reception line 4 receives this and stops transmitting the vehicle transmission phase 3. By the way, when the actual empty status of the taxi changes while driving in Zone A, that is, when a passenger gets on or off the taxi, the single transmitter m3 linked to the taximeter emits a car radio wave modulated by the vehicle signal and the actual empty car signal. This car radio wave is sent to the display means 5 through the zone receiver 2, and the display means 5 changes the displayed actual empty car state, sends a confirmation signal to the zone transmitter 1, and stops transmitting the car transmission phase. do.

In order to further reduce errors in the display of empty cars in each zone,
All you have to do is call all the taxis one by one at regular intervals and check whether they are real or empty.

To check whether a specific taxi is real or empty, call the specific taxi by modulating the carriers of all continuously transmitted zone transmitters with the taxi's vehicle signal, and The configuration may be such that the carrier modulates the carrier with its own vehicle signal and the actual vacant vehicle signal, transmits the modulated signal, and responds.

All you have to do is repeat this operation to check if all taxis are actually empty. Since taxis outside the zone do not respond, the zone transmitter and zone receiver set a timer to confirm the first taxi, so that if there is no response from the taxi after a certain period of time, the next taxi will be called. It is better to limit it by

■ Effects As described above, the taxi calling device according to the present invention displays the vacant car number of each zone at the base, and also uses a wired line to transmit the actual vacant taxi signal from each zone transmitter and zone receiver to the base. is also used to send and receive signals from the waiting sensor means that detects waiting passengers, so there is no need for a dedicated line to transmit waiting signals to the base, and empty cars and waiting cars can be transmitted over the same line. In addition, passengers waiting for a taxi can simply insert their fins and the base will be informed in which zone the passenger is waiting. After inserting a coin, customers will be notified of nearby vacant cars, allowing them to wait with peace of mind.
