Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operation recording device that detects and records desired input information related to the operation status of a vehicle.

Generally, in a device that records the operation status of a vehicle, for example, whether it is in an empty vehicle mode or an actual vehicle mode,
It would be extremely useful to have a device that not only records the time when the mode changes, but also detects and records the distance traveled in each mode.

This is because when managing the operation of a taxi-1 general truck, etc., the vehicle is stopped when the vehicle is empty and there are passengers on board, for example, when the vehicle is stopped for an urgent matter or when waiting for a passenger. In this case, even if there is a 10-minute record, if the mileage is zero, it will not be much of a problem for management purposes, and conversely, if the mileage is 2 km with a 2-minute record in the same mode as above, it will be a management problem. This is because it becomes a problem.

In this way, it is extremely important for the operation recorder to detect and record the distance traveled as necessary input information related to the operation status of the vehicle in terms of operation management.

The present invention has been made in view of the above-mentioned points, and its purpose is to: ■ Input information indicating the empty vehicle or actual vehicle status, input information indicating the on/off of the engine key, and input information indicating the mileage of the vehicle. To obtain a driving recording device.

■ In addition, a reset button is provided that allows only the administrator to reset the counter that measures mileage, such as when leaving the parking lot.This button records the distance traveled from the reset point to the time of each mode change, along with the time. To make it possible to understand the daily driving situation at a glance.

■ Also, engine ON or OFF by engine key signal
To be able to detect and record the distance traveled up to the ON or OFF time using the F signal.

■Furthermore, in the case of a traveling business vehicle, etc., the store can be coded, and upon arrival at the store, the store code can be entered using numerical keys, etc., and the input code, arrival time, and mileage can be recorded together. It is to do so.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a schematic diagram of a taxi, with seat switch SK
is in the back seat when the passenger is seated.

The weight turns it on.

The taxi meter TM is operated by the driver, and the taxi meter TM is operated by the driver.
The figure shows an external view of the taxi meter.

Reference numeral 1 indicates the main body, and reference numeral 2 indicates operation switches. In this example, each switch is locked when pressed and released, and is unlocked when the other switches are pressed.

3 is a fare display, and the side 4 of the main body 1 can be opened with a key kept by the administrator as shown in the figure.

Numeral 5 is a 10 key for inputting a code, and by pressing the print key 6 after pressing the key, the code can be printed and also displayed on the code display 7.

A printing device 8 is built inside the main body.

In other words, only the administrator can view the print results.

9 is an instruction switch R for leaving the warehouse.

Next, a method of controlling this apparatus will be explained based on the block diagram of FIG.

In the figure, the key unit KU corresponds to the operating switch 2 in FIG. 2a, and the state when operating the taxi meter is determined by the combination of the empty vehicle state and the state of the seat switch SK, as described above.

The states of both switches KU and SK are input to the buffer register BP at the first clock φ1 from the clock pulse generator CG, and are stored until the next clock φ1 arrives.

CJ is a comparator that compares the output of the buffer register BF with the outputs of the two switches.

That is, as long as the state of the above-mentioned switch does not change, the CJ output will not be output because there is always a match.

However, if one of the switches KU or SK is turned on or off, the contents of the buffer register BP will not change unless the clock φ1 is output, so they will not match at the moment when the switch is turned, and will match after that.

This comparator CJ shall output an output when there is a mismatch 3CU
is the central control circuit of the taxi meter, which includes sequential control signal generation circuits 81 to S3 for print control, and when the output is output to the comparator CJ, it essentially changes S1 → S2 → S3 and the sequential circuit PRU.
make it work.

CLO is a clock circuit that measures time by frequency-dividing the oscillation output of, for example, a crystal oscillator CZ, and CLR is a register that stores time in binary numbers.

Here, only the hours and minutes are required, so the hours are two digits and the minutes are two digits.

This time information is used for printing, which will be described later.

Next, CO is a two-digit counter, and clear circuit CL
The number of changes can be counted from 2 digits to 99.

First, when the manager opens the door 4 and presses the instruction switch R when leaving the warehouse, the counter CO is reset and input is also input to the central control circuit CU, which activates the sequential circuit PRU.

The counter CO cleared by the printer control sequence control circuit S1 is made to count up, that is, to 01.

In the next circuit S2, the gate G1 is turned on.

When the gate G1 is turned on, the buffer register BR receives the output of the circuit CC which converts the contents of the counter CO and the contents of the buffer register BF into codes as shown in FIG. 4 (this corresponds to the state of the operating switch of the taxi meter).

) Furthermore, time (register CLR output) information is input and stored all at once.

The next circuit S3 is a circuit P that drives and controls the printer PRN.
Activate RC to print the contents of buffer register BR.

The printing device 8 (FIG. 2) uses, for example, a discharge printer, and prints, for example, serial numbers, taxi meter status numbers, and time as print information.

Time records can be used in place of daily driving reports.

When the instruction switch R is pressed, if it is 7:53, 01 1 07,53 will be printed.

After that, if the state of the empty car switch and seat switch SK is changed to a car other than empty, for example, when a car is loaded, the seat switch SK is turned on and the empty car switch is turned off (however, since the inverter is reversed by inverter 1■, the input of buffer BF is set to ``1''. .

), the buffer BF becomes 11, which is converted to 0100 by the code convert CC, represents 4, and is stored in the area of the buffer register BR.

Comparator CJ detects that the switch state has changed,
The sequence control circuit S1→S3 is operated.

Count up the counter CO in circuit S102
shall be.

Data is input into the buffer register BR in the circuit S2.

At this time, it was 02408.02 like in between,
It becomes 02408.02 by printing of circuit S3.

Furthermore, the present invention also includes a device that can detect and record the distance traveled by the vehicle.

Du is a distance counting circuit, and the counted value is stored in register C.
It is stored in O.

The value of the register CO is counted in response to the rotation synchronization pulse P of the vehicle.

RC is a circuit that resets the contents of register CO.

The time, internal status, etc. are printed when the empty car key or seat key changes, but the key point of the present invention is to operate the reset circuit RC with the R key and reset the register CO.
When a state change occurs during subsequent travel and the distance count circuit Du operates, the distance count state is stored in the register Co.
The data is input to the buffer register BR via the gate G1 and its contents are printed out.

FIG. 4 is a block diagram showing another embodiment of the present invention,
The code can be printed by inputting the code using the IO main key shown in Figure 2 and then pressing the print key 6. The key is determined by the circuit,
The code converter Cc converts it into a desired binary code and stores it.

Memorizing the above code is useful in the case of a commercial vehicle that visits various dealerships every day, by pre-coding these dealerships and entering the code of that dealership when arriving at the dealership. The time of arrival at the store and the distance traveled to the distribution store can both be recorded, which is extremely convenient for operation management.

On the other hand, the signal generated by turning the engine key EK ON and OFF is waveform-shaped by the processing circuit EPU and converted into a signal without chattering, and the rising edge of the signal is used as the engine ON signal.
The falling edge is used as an engine OFF signal, and this engine is turned ON.
The OFF signal is also held in the code converter Cc until the sequential signal S1 is output.

Press print key 6 or press engine key EK 0
When the N-OFF is performed, the OR gate OG1 is turned ON, operating the central control circuit Cu, generating sequential signals S1 and S2, and using the S1 signal to transfer the key code area or engine code to the buffer register BR. input.

In this case, the print result is made into two digits like ■, and if the engine ON is printed as OO and the engine OFF is printed as 99, input codes from 01 to 98 can be assigned using the 10 keys.

In other words, it is possible to assign codes to nearly 100 stores, which is sufficient.

In particular, if you record both the ON and OFF states of the engine key, you can also track the elapsed time at each store.

When the signal S1 is output, time information is further input from the register CLR to the buffer register BR, and the contents of the distance count Du for counting the wheel rotation synchronization pulses P of the automobile are also input to the buffer register BR.

The distance counting circuit Du is connected to a delay circuit DL, and is reset when the engine key is turned on by a reset signal from the delay circuit DL when the engine key is turned on.When the next signal 82 is output, the printout control circuit PR
Activate C to print the contents of buffer register BR on printer PRH.

The printed paper has a status code ■, time @, and distance count status O
are recorded respectively.

As described above, the driving recording device of the present invention has the advantage that it is also possible to detect and record the travel distance as necessary input information related to the progress state of the vehicle.
