Description

[Detailed Description of the Invention] The present invention relates to a guidance broadcast method when operating vehicles such as buses and trains along predetermined routes, and is particularly useful for one-man cars in which the driver also serves as a conductor. Concerning a guide broadcast method.

In conventional one-man cars, when the driver reaches an appropriate position between one stop and the next stop, he presses a push button for announcing information, and the magnetic tape rotates and the information is recorded on the magnetic tape. The message ``Next is 〇〇'' is played, and then the magnetic tape stops. According to this, if a driver forgets to press the push button for guidance announcement or presses the push button twice between two stops,
The guidance announcement will be delayed and the wrong guidance announcement will be made. Requiring the driver to not only drive safely but also to avoid making mistakes in operating the pushbutton for guidance announcements places a tremendous mental burden on the driver.

The present invention provides a guidance broadcasting method that automatically broadcasts an appropriate guidance each time a vehicle approaches a guidance broadcasting point, and also easily creates data indicating the guidance broadcasting point for this automatic guidance broadcasting. The purpose is to provide.

This invention includes a rotation detector that generates a pulse every time the wheel rotates a predetermined angle, a counter that counts and stores the number of pulses generated by the rotation detector, and a guide broadcast that starts guidance broadcasting every time a signal is received. A tape recorder that stops every time a broadcast ends, a storage device that stores the count value of the counter when driving the tape recorder, and a value read from the storage device and a count value of the counter are compared. a determination circuit that reads data corresponding to the next guidance broadcasting point from the storage device when a match is detected between the two and outputs a signal for driving the tape recorder; and a switch that outputs a signal each time the tape recorder is operated. loaded onto a vehicle such as a bus or train,
Test drive the vehicle along a predetermined route, operate the switch at each guidance broadcast point during the test drive, and sequentially store the count value of the counter in the storage device each time a signal is output from the switch; After the trial run is completed, the vehicle is driven along the route, and the tape recorder is driven by the output signal of the determination circuit to broadcast guidance.

Therefore, according to the present invention, when the vehicle is traveling with passengers on board, guidance is automatically broadcast at an appropriate location, and the driver only has to pay attention to safe driving. Moreover, since the data indicating the guidance broadcast point for automatic guidance broadcasting is created during the trial run, there is less error compared to creating data from a map, and it is easier to select the appropriate guidance broadcast point. There is no need to spend the effort of entering numerical values using keys, and there are fewer input errors.

Examples of the present invention will be described below. FIG. 1 is a diagram showing an example of a vehicle driving route.
A is the starting stop, B and C are display change stops, and D is the final stop. E to G are intermediate stops. HM to M are guidance broadcast points.

FIG. 2 is a block diagram showing the current position detection and display device and the guidance broadcasting device. 1 is a rotation detector that generates a pulse every time the wheels of the vehicle rotate by a predetermined angle. The rotation detector 1 may be composed of a cam fixed around the axle and a micro switch operated by a protrusion of the cam, or a disc with a hole in the periphery fixed to the axle. Alternatively, a photoelectric switch may be placed at a position where the hole is detected.

2 is a counter that counts and stores the number of pulses output by the rotation detector 1. Reference numeral 3 denotes a storage circuit for storing the current position for displaying sections, which in this embodiment is composed of a counter for storing the number of sections. 4 is a display provided in front of the driver's seat, which displays the stored values of the memory circuit 3. 5 is a door opening/closing detector that emits a relatively short pulse when the vehicle door is closed. Reference numeral 6 denotes a storage device that stores in advance the counted value of the counter 2 when changing the stored value of the storage circuit 3, and the first storage area stores data (numerical value) corresponding to the distance from the first stop A to the display change stop B. )
is stored, and data corresponding to the distance from the initial stop A to the display change stop C is stored in the second storage area.

Reference numeral 7 denotes a register that stores a value read from the storage device 6 whose address is specified by the storage value of the storage circuit 3 . 8 calculates the difference between the counted value of the counter 2 and the stored value of the register 7 based on the signal output from the opening/closing detector 5, compares the difference with a predetermined value set internally, and determines that the difference is a predetermined value. This is a determination circuit that outputs a pulse to add "1" to the stored value in the storage circuit 3 when it detects that it is less than the value. The determination circuit 8 constantly compares the difference between the count value of the counter 2 and the stored value of the register 2 with a predetermined value, and when the difference becomes less than the predetermined value, determines whether the open/close detector 5 has issued a signal. It may be of such a type that a pulse is given to the memory circuit 3 upon receiving a signal from the opening/closing detector 5. Of course, in this case, even if a signal is received from the open/close detector 5 when the difference is greater than a predetermined value, it is necessary to prevent the pulse from being output to the memory circuit 3.

Reference numeral 11 denotes a memory circuit for storing the current position for guidance broadcasting, and is composed of a counter similar to the memory circuit 3. 12 is a tape recorder for broadcasting information. Reference numeral 13 denotes a storage device in which the count value of the counter 2 at the time of starting the guidance broadcast is stored in advance, and has a first storage area to a sixth storage area. The first storage area of the storage device 13 stores data (numeric values) corresponding to the distance from the first stop A to the first guidance broadcast point H, and the second storage area stores the distance from the first stop A to the second guidance broadcast point H. Data corresponding to the distance to point I is stored. Similarly, the third
The storage area to the sixth storage area store data corresponding to the distances from the first stop A to the third guidance broadcast point J to the sixth guidance broadcast point M, respectively.

Reference numeral 14 denotes a register that stores a value read from the storage device 13 whose address is specified by the storage value of the storage circuit 11 . 15 is a determination circuit that compares the counted value of the counter 2 and the counted value of the register 14 and outputs a pulse when the two match. The pulse issued by the determination circuit 15 is applied to the memory circuit 11 to add "1" to the stored value of the memory circuit 11, and at the same time, is applied to the tape recorder 12 to start the guidance broadcast. Note that the tape recorder 12 is configured to automatically stop feeding the tape and stop broadcasting when the prerecorded guidance broadcast ends for each guidance broadcast point.

Although not shown, the vehicle is also provided with a fare display device and a numbered ticket issuing machine in addition to the above. As is well known, a numbered ticket issuing machine prints the number of the section to which the boarding stop belongs on the tip of a roll of paper, then cuts the tip to create a numbered ticket and sends it out to the exit. Passengers boarding the vehicle take out the numbered ticket from this exit and board the vehicle. The fare display device displays the fare corresponding to the section printed on the numbered ticket, and is located at the top of the back of the driver's seat where passengers can see it, or where it can be seen by passengers and, if necessary, the driver. It is installed in the uppermost position at the front of the vehicle. The driver recognizes the boarding fare of each passenger from the numbers printed on the numbered ticket and the display on the display 4 or the fare display device when each passenger gets off the train. The display on the fare display device and the numbers for printing sections by the numbered ticket issuing device are changed in conjunction with a change in the display on the display 4 or a specific information broadcast by the tape recorder 12. Of course, the judgment circuits 8 and 15, the memory circuit 3
Alternatively, a determination circuit, a memory circuit, a memory device, and a register corresponding to the memory devices 6 and 13 and the registers 7 and 14 may be provided and changed independently.

When a reset push button (not shown) is operated when starting the service from the first stop A, the stored values of the counter 2, memory circuits 3 and 11, and registers 7 and 14 are reset to "0". When counter 2 and register 14 are reset, the stored value of counter 2 and register 14 are
Since the stored value of 0 matches the stored value of , the determination circuit 1
A pulse is output from 5 and supplied to the memory circuit 11,
The stored value of the storage circuit 11 becomes "1". As a result, data is read from the first storage area of the storage device 13 to the register 14. At the same time, a pulse from the determination circuit 15 is supplied to the tape recorder 12, and a departure guide is broadcast.

Subsequently, when the boarding/exit door is closed, the value stored in the counter 2 and the value stored in the register 7 match, and the door opening/closing detector 5 outputs a signal. A pulse is supplied to the memory circuit 3, the memory value of the memory circuit 3 becomes "1", and data is read from the first memory area of the memory device 6 to the register 7. Thereafter, the vehicle starts traveling toward the final stop D. When the vehicle travels, a number of pulses proportional to the distance traveled are emitted from the rotation detector 1 and added to the counter 2.

When the vehicle travels and reaches the first guidance broadcast point H,
The count value of counter 2 becomes equal to the value stored in register 14. The determination circuit 15 detects this and outputs a pulse. This pulse is applied to the tape recorder and storage circuit 11. When a pulse is applied to the tape recorder, an announcement is made that the next stop is B. When a pulse is applied to the memory circuit 11, the memory value of the memory circuit 11 becomes "2", and the memory device 1
Data is read from the second storage area No. 3 to the register 14. Note that the first guidance broadcast point H is always approximately the same point when the vehicle is a train, but when the vehicle is a bus, it is not always the same point but changes within a range of several tens of meters before and after. However, since the distance between each stop is approximately several hundred meters to several kilometers, the guidance broadcast is always made between the first stop A and the next stop B. The same applies to the second guidance broadcast point I to the sixth guidance broadcast point M, so a detailed explanation thereof will be omitted below.

When the vehicle arrives at the display change stop B, the difference between the count value of the counter 2 and the value stored in the register 7 becomes less than or equal to a predetermined value. This predetermined value corresponds to the maximum error in travel distance, for example, several tens of meters in the case of a bus. At display change stop B, the door is opened and
Passengers get on and off. Once passengers have boarded and alighted, the door is closed. This causes the opening/closing detector 5 to issue a signal. At this time, as mentioned above, since the difference between the stored value of the counter 2 and the stored value of the register 7 is less than the predetermined value, a pulse is supplied from the determination circuit 8 to the storage circuit 3, and the stored value of the storage circuit 3 becomes " 2”, the data is transferred from the second storage area of the storage device 6 to the register 7.
is read out.

Thereafter, in the same manner, the second guidance broadcast point I to the sixth
While traveling through a guidance broadcast point M, a guidance broadcast corresponding to each point is performed, and the display on the display 4 is changed at a display change stop C. Note that even if the door is closed at intermediate stops E to G and a signal is output from the opening/closing detector 5, the difference between the stored value of the counter 2 and the stored value of the register 7 does not become less than a predetermined value, so the display The display of 4 is not changed.

In the above embodiments, the opening/closing detector 5 is one that outputs a signal when the door is closed, but it may also be configured to output a signal when the door is opened. In this case, if the same boarding section as in the above embodiment is used, stops E and F are defined as display change stops, and the first storage area and second storage area of the storage device 6 contain the information for stops A to E, respectively. It is necessary to store a value corresponding to the distance and a value corresponding to the distance from stop A to F. In this case, it is better not to change the display on the charge display device (not shown) in conjunction with the change in the display on the display 4.
This is because the fare changes the moment the door opens and passengers get off the train, which confuses passengers.

Furthermore, in the above embodiments, the display on the display 4 and the drive of the tape recorder are changed using separate determination circuits, memory circuits, etc., but what is to be driven at what point is stored. If it is set up, one computer can time-divisionally change the display on the display 4 and drive the tape recorder, as well as control the display on the fare display device (not shown) and the characters printed on the numbered ticket issuing machine. be able to. In this case, the computer can be called a determination circuit.

FIG. 3 is a block diagram of an electrical circuit used in the method for storing necessary data in the storage devices 6, 13 shown in FIG. The storage device 6 shown in FIG.
13 has a data shift function. 21 and 22, when operated, shift the stored values of the storage devices 6 and 13 and store them in the register 2.
This is a manually operated switch that outputs a signal for reading the stored value into the storage devices 6 and 13. switch 2
An opening/closing detector 5 can be used instead of the opening/closing detector 1. In this case, during the trial run, it is necessary to stop at the display change stop and open/close the door, but not to open/close the door at other stops.

When a test run is started from the starting stop A shown in FIG. 1, when a reset push button (not shown) is operated, the stored value of the counter 2 is reset to "0". Thereafter, the vehicle is driven toward terminal station D. A suitable point before reaching the display change stop B is selected and that point is set as the first guidance broadcast point H, and when the vehicle has traveled to the first guidance broadcast point H, the switch 22 is operated. This operation may be performed by the driver or by a fellow passenger during the trial run. When the switch 22 is operated, the switch 22
A shift pulse is output from and supplied to the storage device 13. When the storage device 13 receives the first shift pulse, it reads the count value of the counter 2 into the sixth storage area.

Subsequently, upon arriving at the display change stop B, the switch 21 is operated. Then, a shift pulse is output from the switch 21 and supplied to the storage device 6. When the storage device 6 receives the first shift pulse, it reads the count value of the counter 2 into the second storage area.

Furthermore, when the switch 22 is operated at the second guidance broadcast point I while driving, the storage device 13 receives a shift pulse from the switch 22 and shifts the stored value in the sixth storage area to the fifth storage area. The count value of counter 2 is read into the sixth storage area. Similarly, the switch 22 is operated at the third guidance broadcast point J, and the value stored in the fifth storage area of the storage device 13 is transferred to the fourth storage area, the value stored in the sixth storage area is transferred to the fifth storage area, and so on.
The stored value of counter 2 is read into the sixth storage area.

When the switch 21 is operated upon arriving at the display change stop C, the storage device 6 transfers the stored value of the second storage area to the first storage area and the stored value of the counter 2 to the first storage area.
Read into storage area.

Also from the 4th guidance broadcast point K to the 6th guidance broadcast point,
Switch 22 is operated in the same manner. After the switch 22 is operated at the sixth guidance broadcasting point, the first to sixth storage areas of the storage device 13 are stored with information from the first stop B to the first guidance broadcasting point H to the sixth guidance broadcasting point M, respectively. The value corresponding to the distance is stored.

After that, when passengers are loaded and the train travels from the first stop A to the last stop D, as explained in Fig. 2, an appropriate guidance announcement will be automatically made each time it arrives at each guidance announcement point H to M. become.

In FIG. 3, two switches are provided for generating shift pulses, but one switch may be used, and a separate switch may be provided for distributing whether the shift pulses are supplied to the storage device 6 or the storage device 13.

Note that when using a memory device 13 that does not have a shift function, the memory circuit 11 for specifying an address is also used, or a similar memory circuit is provided so that the rising edge signal of the signal output by the switch 22 is Take it out and add "1" to its memory circuit,
The fall signal of the signal output by the switch 22 is extracted and used as a data read signal for the storage device 13, and the value of the counter 2 is used as the address (first storage area to sixth storage area) of the storage device 13 specified by the stored value of the storage circuit. It is a good idea to memorize it in one of the following.

FIG. 4 shows a route that is different from the route shown in FIG. , 13. FIG. A rising signal of the signal outputted from the switch 22 is taken out by a differentiating circuit 31 and supplied to one input terminal of AND circuits 32 and 33, while a not circuit 34 and a differentiating circuit 3
5, the falling signal is taken out and becomes a step signal for the binary counter 36. The other of the two input terminals of the AND circuits 32 and 33, which is different from the one described above, is connected to the "0" and "1" output terminals of a binary counter 36, respectively.
The output signals of the AND circuits 32 and 33 become shift input signals of the storage devices 13 and 6, respectively.

At the start of the trial run, counters 2 and 36 are reset to "0". Then, when the vehicle travels along a predetermined driving route, the count value of the counter 2 becomes a value proportional to the traveling distance, as already explained. When the switch 22 is operated at the first guidance broadcast point, a signal is first output from the differentiating circuit 31. At this time, since the counter 36 is outputting a signal to the "0" output terminal, the output signal of the differentiating circuit 31 passes through the AND circuit 32 and becomes a shift signal for shifting the value stored in the storage device 13. After this, when the output signal of the switch 22 disappears, a signal is output from the not circuit 34 and sent to the counter 36 via the differentiating circuit 35.
progress.

Then, when you arrive at the next stop, switch 22
is operated, a shift pulse is supplied to the storage device 6 via the differentiating circuit 31 and the AND circuit 33, a signal is output from the NOT circuit 34 and is supplied to the counter 36 via the differentiating circuit 35, and the counter 36 outputs the output terminal "0" output signal. Thereafter, the storage devices 13 and 6 alternately and sequentially store data in the same manner.
