Another object of the present invention is to make it possible to record the time each time the number of people getting on and off the bus is counted and recorded.

By automatically performing the above operations, it is possible to eliminate the large number of additional personnel traditionally required to conduct the above investigations over a certain period of time, resulting in significant cost savings, as well as the ability to continuously conduct such investigations at all times. You can always keep track of traffic conditions and adjust the season, day, and season of traffic.
Even if there is a change due to the time of day, etc., this can be immediately known.

In order to achieve the above object, the present invention includes a counter for counting the number of passengers (hereinafter referred to as a tenth counter).

), a counter that counts the number of people getting off the train (hereinafter this will be referred to as the 20th counter).

Next, the operation will be explained.

When the bus stops at a stop and at least one of the boarding and disembarking doors is opened, one or both of the switches 2 and 3 are closed in response to the opened door.

When at least one of the switches 2 and 3 closes, the output of either the inverter 8 or 10 becomes (Q", and the output of the AND circuit 12 becomes %Q", and the output of the AND circuit 12 becomes %Q".
A differential output is generated from at least one of the two, and this differential output is applied to the flip-flop 7 via the OR circuit 6, and the flip-flop 7 is set.

When flip-flop 7 is turned on, its set output is applied to one input of AND circuits 15 and 160, respectively.

AND circuits 15 and 16 are AND gates and are opened by the seven outputs of flip-flop 7.

Then, each time a passenger passes through the boarding door position and gets on the train, the photoelectric switch 13 generates a detection signal, and this signal is inputted to the counter 17 through the andgame g15, and the counter 17 detects the generation of the signal. Count the frequency.

Furthermore, each time a passenger exits the vehicle through the position of the exit door, the photoelectric switch 14 generates a detection signal, and this signal is inputted to the counter 18 through the AND gate 16, and the counter 18 outputs the signal. Count the number of times.

If only one of the boarding door and the disembarking door is open, that is, if only one of the boarding and disembarking passengers is present, only the counter 17, 18 corresponding to the opened door is displayed. Perform counting.

Then, once you get on and off, the door that was open will close.

Therefore, the closed switch 2 and 3 is opened, and as a result, both switches 2 and 3 are opened.

At this time, since there is no input to both inverters 8 and 10, their outputs both become X1", so the output of AND circuit 12 also becomes "1", and flip-flop 7 is reset by this output 11".

This set output is applied to temporary storage circuits 19.20, which temporarily store the counts of counters 17 and 18, respectively.

Counters 17 and 18 are cleared by the reset output of flip-flop 7.

Note that when the output of the OR circuit 6 is generated, this output is also applied to the storage device 28, and the storage device 28 stores the output of the decoder 27 at that time by adding this output.

Further, when an output from the AND circuit 12 occurs, this output is also applied to the storage device 29, and the storage device 29 stores the output from the decoder 27 at this time.

That is, the storage device 28 stores a signal indicating the time when the bus stopped at the bus stop and at least one of the doors was opened.
The storage device 29 stores the time when both doors are closed for the bus to depart from the bus stop.

When the flip-flop 7 is reset, its reset output is also input to the write control circuit 25;
outputs ■ or ■ sequentially for a certain period of time.

When the output ■ is generated, the gate E22 is opened, and the count value of the counter 18 stored in the temporary storage circuit 20, that is, the number of passengers getting off the train, is sent to the write magnetic head 24 via the amplifier 23.
is input.

The output (2) of the control circuit 25 is also applied to the flip-flop 32 to set it, so the motor 33 rotates upon receiving the set output of the flip-flop 320 and transports the magnetic tape 34.

Therefore, data in the storage circuit 20 is magnetically recorded on the magnetic tape 34 by the magnetic head 24.

Then, when the output (■) of the control circuit 25 occurs, the gate 21 is opened, and the count value of the counter 17 stored in the temporary storage circuit 19, that is, the number of passengers, is inputted to the magnetic head 24 via the amplifier 23, and the magnetic tape 34 is inputted to the magnetic head 24 via the amplifier 23. magnetically recorded.

Furthermore, when the output (2) of the control circuit 25 occurs, the gate 30 is opened, and the memory of the storage device 28, that is, the data of the time when the bus stopped, is inputted to the magnetic head 24 via the amplifier 23, and is magnetically recorded on the magnetic tape 34. Further, when the output (2) of the control circuit 25 occurs, the gate 31 is opened, and similarly, the data stored in the storage device 29, that is, the data of the bus departure time, is magnetically recorded on the magnetic tape 34 by the magnetic head 24.

Incidentally, when the output (2) of the control circuit 25 is generated, this output is applied to the reset input of the flip-flop 32, the flip-flop 32 is reset, the rotation of the motor 33 is stopped, and the transport of the magnetic tape 34 is stopped.

If only one of the storage devices 28 and 290 is provided, one of the outputs (1) and (2) of the control circuit 25 is omitted.

Note that at the beginning of recording on the magnetic tape 34 by the magnetic head 24, a signal indicating the stop name may be recorded.

The above operations are automatically performed when the bus stops at a bus stop, opens at least one of the boarding door and the exiting door, and then closes both doors.

The number of passengers boarding and disembarking at each Gagatsuko stop is automatically counted and recorded, and the time of stop (when the train stops and one of the doors is opened) or the time of departure (however, both doors are opened) is automatically counted and recorded. Since at least one of the two times (both closed times) is automatically recorded at the same time, the data necessary for creating and revising bus service schedules can be automatically recorded without the need for a large amount of manual labor, and can be recorded at all times. Can be recorded continuously.
