〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram showing an embodiment of a taxi operation recording apparatus according to the present invention. In the figure, reference numeral 1 is a replaceable chart paper, which is a drive source not shown so as to rotate once in 24 hours a day. Is driven to rotate in one direction. Reference numeral 2 is a recording needle supported and fixed on a needle support plate 3 made of a magnetic material, and the tip of the recording needle is always in contact with the chart paper 1, and the needle support plate 3 reciprocates in the direction of the arrow shown in the figure. By doing so, recording with a predetermined width is performed on the chart paper 1 in the direction orthogonal to the rotation direction. Reference numeral 4 denotes an electromagnetic magnet as an electromagnetic driving means that attracts the needle support plate 3 when it is energized by energization. The needle support plate 3 is constantly biased by spring means (not shown) in a direction that resists the attraction force. And is reciprocated in the direction of the arrow shown in the figure. Reference numeral 5 denotes a speed sensor as a travel detecting means for detecting the travel speed of the taxi vehicle, which generates a speed signal according to the travel speed and detects a substantially non-traveling state of the taxi vehicle, that is, a stopped state. It is input to the low speed detection circuit 6 as a non-traveling detecting means.

The chart paper 1, the recording needle 2, the needle supporting plate 3, the electromagnetic magnet 4 and the speed sensor 5 are housed in the tachograph body A. In the tachograph main body A, in addition to these, various speed recording needles, engine speed recording needles (not shown), and various kinds of recording speed recording or engine speed recording on the chart paper 1 by driving these recording needles are also provided. Mechanisms are also provided, but since they are not directly related to the present invention, illustration and description thereof are omitted.

Reference numeral 7 denotes a real vehicle switch serving as an empty vehicle detecting means for detecting an empty vehicle state, which may be a tariff switch in the taximeter B. The switch 7 is turned on when the vehicle is loaded with passengers and turned off when the vehicle is empty. The real vehicle switch 7 has one end connected to a vehicle-mounted battery and the other end connected to the input circuit 8.

The low speed detection circuit 6 detects that the vehicle speed is below a predetermined speed based on the speed signal from the speed detection sensor 5,
An H-level detection signal that indicates a substantially stopped state when the vehicle speed is below a predetermined speed, and an L-level detection signal that indicates that the vehicle speed is not substantially stopped when the vehicle speed is equal to or higher than the predetermined speed. Are output respectively, and this is output to the AND circuit 9
To the reset input R of the RS flip-flop (F / F) 10. The RSF / F10 is reset when its reset input R rises from L to H level, that is, when the taxi vehicle stops, and its output Q
Is inverted from H level to L level.

Further, the input circuit 8 sends an H level signal when the empty vehicle switch 7 is turned off by the empty vehicle.
When each is turned on by the actual vehicle, it outputs an L level signal and supplies it to the other input of the AND circuit 9.

The output signal of the AND circuit 9 in which the output of the low-speed detection circuit 6 is connected to one input and the output of the input circuit 8 is connected to the other input is input to the reset input of the frequency dividing circuit 11 formed of a counter. Has been done.

The clock signal is input to the input of the frequency dividing circuit 11 from the oscillation circuit 12, and when the reset input goes from the H level to the L level, the counting content is reset and the counting operation is stopped. And the reset input is from L to H
At the level, the reset state is released and the oscillation circuit 1
Start counting from 1 of the clock signal from 2. The frequency divider circuit 11 divides the clock signal from the oscillator circuit 12 by a predetermined frequency division ratio by counting, and outputs the first and second frequency division outputs O ₁ thereof.
And the divided signals are output to O ₂ , respectively. Frequency divider 11
The first frequency division output O _{1 of} is a relatively large frequency division ratio (for example, 5
The frequency division signal is output by (min.) And is input to the set input S of the RSF / F 10. The second frequency division output O of the frequency division circuit 11
₂ outputs a frequency division signal with a relatively small frequency division ratio, and supplies the frequency division signal to one input of the output Q of the RSF / F10 to the other input of the AND circuit 13 to which the output signal is input.

When the RSF / F10 is set by the output of the frequency dividing circuit 11 and its output Q becomes H level, the AND circuit 13
To the output through the second frequency division output O _{2 of the} frequency division circuit 11.
The frequency-divided signal output to is transmitted. The frequency-divided signal of the clock signal sent to the output of the AND circuit 13 is supplied to the input of the drive circuit 14 that drives the electromagnetic magnet 4. The drive circuit 14 is a power switch 1 as a cooler-on detecting means for detecting an on-state of a vehicle-mounted cooler.
Power is supplied from the battery via 5, the power switch 15 of the cooler is turned on, and the frequency division signal is input from the AND circuit 13 only.
A drive current is supplied to the device to energize it.

As described above, when the electromagnetic magnet 4 is biased, the needle support plate 3 is attracted and the recording needle 2 supported by the needle support plate 3 is moved downward in the figure, and the attraction force is released by releasing the bias. Then, the needle support plate 3 is returned by the spring means (not shown) and the recording needle 2 moves upward in the figure. This operation is repeated in the cycle of the frequency-divided signal output to the _second frequency-divided output O ₂ of the frequency-dividing circuit 11, but since the chart paper 1 is rotationally driven at this time, the operation is performed on the chart paper 1. The bar-shaped recording as shown in the figure, which is filled with the recording needle 2, is performed.

The overall operation will be described below with the configuration of each unit described above.

Now, when the taxi vehicle is stopped from the running state or becomes a certain vehicle speed or less, the output of the low speed detection circuit 6 becomes H level, and RS
F / F10 is reset. At this time, if the actual vacant vehicle switch 7 is off, that is, if no passenger is on the vehicle, both inputs of the AND circuit 9 become H level, and the AND
The output of the circuit 9 becomes H level. As a result, the frequency divider circuit 11 is released from the reset state, and the clock signal from the oscillator circuit 12 starts counting from 1. When the frequency dividing circuit 11 counts a period corresponding to 5 minutes, the first and second frequency division outputs O
_A frequency-divided signal is output to ₁ , which causes RSF / F10 to be set and its output Q to go high. Therefore, the frequency division signal output to the _second frequency division output O ₂ of the frequency division circuit 11 is supplied to the drive circuit 14 through the AND circuit 14. At this time, if the power switch 15 of the cooler is turned on, the drive circuit 14 intermittently energizes the electromagnetic magnet 4 in response to the frequency division signal from the _second frequency division output O _{2 of the} frequency division circuit 11, and Energize. Therefore, predetermined recording is performed on the chart paper 1.

If the taxi vehicle starts running before the frequency dividing circuit 11 has been reset for 5 minutes, the output of the low speed detection circuit 6 becomes L level, which causes the output of the AND circuit 9 to become L level. 11 is reset again and held in that state. Due to the reset state of the frequency dividing circuit 11, the frequency dividing signal is not output and the drive circuit 14 does not energize the electromagnetic magnet 4.

Further, when the taxi vehicle changes from an empty vehicle to an actual vehicle before the lapse of 5 minutes, the output of the input circuit 8 becomes L level and the output of the AND circuit 9 also becomes L level, so that the frequency dividing circuit 11 is in the reset state. Therefore, the frequency division signal from the frequency division circuit 11 is not input to the output of the AND circuit 13, and even if the cooler power switch 15 is turned on, the electromagnetic magnet 4 is intermittently energized by the drive circuit 14. The recording needle 2 is not reciprocated, and bar-shaped recording is not performed on the chart paper 1.

As described above, according to the operation recording device described above, for example, 5
If the power switch of the cooler is turned on when the taxi vehicle is substantially stopped for a predetermined time of about a minute and is in an empty state, a predetermined recording is performed on the chart paper 1. Therefore, it is possible to grasp and manage the inefficient state of taxi vehicle operation by recording on chart paper.

〔effect〕

As described above, according to the present invention, on the chart paper on which the running speed, engine speed, etc. of the taxi vehicle are recorded, the taxi vehicle is not running, the taxi vehicle is empty, and the cooler is on. Since the specified records are recorded, it is possible to obtain a record of the usage status of the cooler in the taxi vehicle in relation to the presence or absence of passengers, and the records on the chart paper can be used to effectively identify the inefficient operation status of the taxi vehicle. It has become possible to grasp and use it effectively for taxi vehicle operation management.
