Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a punctual operation instruction device for vehicles such as buses and trains.

Transportation means such as buses and trains have a predetermined time required between each stop, and ideally, they should operate according to the predetermined schedule. However, it is difficult to actually operate the train according to the schedule due to congestion on the roads and variations in passenger boarding and alighting times.

By the way, the judgment as to whether or not the train is operating according to the schedule has conventionally been made by comparing the timetable provided in the driver's seat with the clock carried by the driver. Therefore, each time the driver arrives at each stop, he compares the timetable with the clock, determines whether the train is ahead or behind the schedule, and then mentally calculates the time of advance or delay. Therefore, each time the driver arrives at each stop, he must perform mental calculations, which places a heavy burden on the driver. It also has the disadvantage of lacking accuracy.

An object of the present invention is to provide an on-time operation instruction device that calculates the progress and delay at each stop on behalf of the driver, displays the calculation results on a display, and directly reads and displays the progress and delay times. .

There are two possible ways to display the progress and delay at each stop.

One method is to store the required time from the first train to each stop in a memory device. When using this method, a timing device is installed that starts timing from the first train, and a comparator compares the time value of this timing device with the required time value read from the memory, and the comparison result is displayed on the display. By doing so, it is possible to display the progress and delay at each stop.

In the case of the first invention, the stopping time at each stop is also cumulatively added and added as an element subject to advance/delay. Therefore, according to the first invention, it is possible to display progress and lag throughout the route.

The second method is to store the required time between each stop in a memory. In this method, a timing device is installed that starts timing every time the train departs from each stop, and a comparator compares the time value of this timing device with the required time value read from the memory, and the comparison result is All you have to do is display it on the display.

In the case of the second invention, since the timing device is reset when the vehicle leaves the stop, the stop time at the stop is excluded from timing. Therefore, the lead/delay time value displayed on the display 9 is the sum of the lead/delay time value in the previous section and the required time value in the next section. As a result, the stop time at the stop is not included in the calculation, but since the previous comparison result is added to the required time value read next, the time value held in register 4 is the value accumulated from the first train, and the stop time is multiplied by the shorter stop time. If you do this, you can get the correct advance and delay times.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the invention. This example shows a case where the storage device stores the time required from the first train to each stop.

In the figure, 1 indicates a storage device. The storage device 1 can be a tape recorder for in-vehicle broadcasting or a semiconductor memory. If a tape recorder is used, the required time values can be stored as shown in FIG. That is, it is assumed that the magnetic tape 11 is fed in the direction of the arrow 12, and the memories 13a, 13b, 1 are used to broadcast the next stop name on the first track.
3c... is stored. Each memory 13a, 13b, 1
At the end of 3c... there is a stop signal 14 for another truck.
a, 14b, 14c... are stored, and this stop signal causes the magnetic tape 11 to move to the stop lines 15a, 15b,
It is automatically stopped at 15c... The time required to reach each stop is determined by each stop line 15 on this magnetic tape 11.
Stored immediately after a, 15b, 15c... 16
a, 16b, 16c, . . . indicate storage of the required time values from the first train to each stop, respectively. The tape recorder is therefore arranged to begin playback upon departure from each stop. For this purpose, for example, it may be possible to configure the train so that the driver operates a switch by pressing a button or the like every time the train departs from each stop, but in reality it is more reliable to provide a device that automatically detects departure. The departure detector can be constructed, for example, as shown in FIG. In FIG. 1, 2 indicates a departure detector. Switch 2a is a switch that is turned on when the vehicle is stopped, and 2b is a switch that is turned on when a door is opened.
It is detected by the AND gate 2c that both of the transistors b are turned on, and, for example, a flip-flop 2d is set. The set output of flip-flop 2d is supplied to one input terminal of AND gate 2e, and H logic is supplied to the other input terminal of AND gate 2e through switch 2f, which is turned on when the door is closed.

With this configuration, an output signal is obtained from the AND gate 2e when the vehicle stops at each bus stop, handles passengers, and closes the door. By supplying this output signal to the storage device 1, the value of the time required from the first train to the next stop is read out. According to this configuration, when the vehicle stops at a place other than a stop, the departure detector 2 does not output a detection signal. In addition, the bus may pass through the bus stop due to reasons such as when the bus is full or there are no passengers getting on or off the bus. In such a case, the driver operates manual switch 3 when passing the stop.
What is necessary is to activate the memory device 1. Furthermore, the flip-flop 2d may be configured to be reset by stop signals 14a, 14b, 14c, . . . from the tape recorder.

The required time value read from the memory 1 is stored in the register 4, and the register 4 supplies the required time value to the comparator 5. A time value is supplied to the comparator 5 from a time measurement device 6 . The timekeeping device 6 is reset at the time of the first train train by operating a switch 7, for example, and starts timekeeping, and supplies the timed value to the comparator 5.

A latch circuit 8 is provided on the output side of the comparator 5.
Latch the state. For this purpose, the stop detector 2
The output of the AND gate 2c is supplied to the latch circuit 8, and the state of the comparator 5 is latched when the door is opened while the vehicle is stopped. That is, if the required time value from the register 4 is A and the time value from the clock device 6 is B, the latch circuit 8 latches the value AB. Here, when A>B, it means that the diagram is ahead of the planned time, and at this time, the latch circuit 8
A value corresponding to the plus sign is added to and latched. Further, when A<B, the timetable is delayed from the scheduled timetable, and at this time, a value corresponding to the minus sign is added to the latch circuit 8 and the timetable is latched. The value AB latched by the latch circuit 8 is displayed on the display 9 together with the sign. Therefore, for example, when "+10" is displayed, it is read as "10 minutes ahead", and when -10 is displayed, it is read as "10 minutes late". Incidentally, instead of using the + and - signs, the advance and the delay can also be directly displayed using a lamp or the like.

The comparison result latched by the latch circuit 8 is supplied to the register 4 and added to the value of the time required to reach the next stop. At this time, if the sign latched by the latch circuit 8 is positive, then it is read out from the storage device 1 and taken into the register 4. Add to the time required from the first train to the next stop. Therefore, in the case of advance, the next required time value is revised to a value larger than the required time value determined on the diagram.

On the other hand, when the sign latched in the latch circuit 8 is negative, the delay time value is subtracted from the time required from the first train to the next stop, which is taken into the register 4. Therefore, the next required time value is modified to a smaller value.

By adding the comparison result to the register 4 in this manner, the cumulative calculation of advance and delay at each stop is executed, and the cumulative value of advance and delay each time the train arrives at each stop from the first train is displayed on the display 9.

FIG. 3 shows an embodiment according to the second method of the invention. That is, a case is shown in which the storage device 1 stores the required time between each stop. Therefore, the difference from the embodiment shown in FIG. 1 is that the timing device 6 is reset each time the train departs from each stop, and starts timing from that point. Therefore, the detection signal of the departure detector 2 is supplied to the reset terminal 6a of the timekeeping device 6, and each time the train departs from each stop, the contents of the timekeeping device 6 are reset and new timing is started. When the next stop is reached and the door is opened, the contents of the comparator 5 are latched into the latch circuit 8, and as the train progresses and delays, plus and minus signs are added to the latch contents, and along with the sign. This embodiment is the same as the embodiment shown in FIG. 1 in that the contents of the comparator 5 are displayed on the display 9 and the contents of the latch are added to the register 4.

Even with this configuration, the display value displayed on the display 9 is the cumulative value of advance and delay from the first train.

FIG. 4 shows another embodiment according to the second method.
In this example, a case is shown in which a presettable up/down counter is used as the comparator 4. Therefore, in this case, the timing device 6 may be configured to output clock pulses of a constant period, and the time required between each stop preset from the register 4 can be calculated by the clock pulses output from the timing device 6. Configured for sequential subtraction. The rest of the structure is the same as the embodiment shown in FIGS. 1 and 3.

As explained above, according to the present invention, each time the driver arrives at each stop, the timetable is advanced and the delay time is displayed, so the driver can judge the speed of travel to the next stop from the display. This can reduce the burden on staff.

Although the storage device 1 has been described above as a tape recorder, it can be replaced with a semiconductor memory as described above. When using a semiconductor memory, the address counter is incremented by the output of the train departure detector 2, and the read address is incremented one by one, and the required time between each stop or from the first train to each stop is calculated from each address. It can be configured to read out a value of the time required to reach the destination. In addition, this invention device includes a storage device 1 such as a tape recorder.
It will be readily understood that the register 4, the comparator 5, the clock device 6, the latch circuit 8, and the display device 9 can be separately constructed, and these can be replaced by, for example, a microprocessor.
