Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electronic taxi meter, and more specifically, in response to the operation of the "rental fare" tariff pushbutton,
The distance sensor calculates the taxi fare based on the signal generated as the vehicle travels, displays the calculated taxi fare on the fare display section to inform passengers of the fare, and then "pays" the taxi fare after the business ends. This invention relates to an electronic taxi meter that receives fares from passengers by operating a push button, and then prepares for the next service by operating an "empty car" tariff push button.

[Problems to be solved by conventional techniques and ideas]

Generally, in this type of electronic taximeter, even if the fare is received from the passenger based on the amount displayed on the fare display section by operating the "Payment" tariff pushbutton after business hours, the "Empty Car" tariff pushbutton is If you leave the tariff as "Payment" without operating it, when a signal is input from the distance sensor as the taxi vehicle travels, calculations will be made based on that signal and an additional charge will be added. was.

Therefore, if the driver forgets to press the "empty car" tariff button at the end of the business due to carelessness or busyness, the driver will have to pay the additional fee to the taxi company. It will stop happening. In addition, when the burden of such an additional charge occurs, the driver's psychology is to avoid the burden of this additional charge, leave the tariff as "paid" and pick up the next passenger, and then drive. This was causing fraud in which customers were forced to pay extra fees. Such fraud not only causes trouble with passengers, but also poses a credibility problem for taxi companies.

Therefore, in view of the above-mentioned conventional problems, the present invention
To provide an electronic taximeter capable of preventing an additional charge from being incurred due to driving at a mistariff position where one forgets to operate an "empty car" tariff pushbutton after operating a "payment" tariff pushbutton. It is an object.

[Means for solving problems]

In order to solve the above-mentioned problems, the electronic taximeter has been developed according to the present invention. As shown in the basic configuration diagram of FIG. The calculation unit 4a calculates the taxi fare based on the signals generated as the vehicle travels, displays the taxi fare calculated by the calculation unit 4a on the fare display unit 6, and informs the passengers of the fare. "Payment" tariff push button 3a
A tariff detection means for detecting the operating state of the "Payment" tariff push button 3a, in which the fare is received from the passenger by operating the "Empty Car" tariff push button 3d, and the "vacant car" tariff push button 3d is then operated to prepare for the next business operation. 4b, a traveling detecting means 4c for detecting the traveling of the vehicle based on the signal from the distance sensor 1, and when the tariff detecting means 4b detects the operation state of the "Payment" tariff push button 3a, the traveling detecting means 4c detects the traveling of the vehicle based on the signal from the distance sensor 1; The present invention is characterized by comprising an alarm means 10 which generates an alarm sound in response to detection of vehicle running by the means 4c.

[Effect]

In the above configuration, the alarm means 10 is a "payment"
When the tariff pushbutton 3a is in the operating state, the vehicle generates an alarm sound indicating that the vehicle is running, so it is important to forget to switch from the "payment" tariff state to the "empty vehicle" tariff state when the vehicle starts running after receiving the fare from the passenger. In other words, it notifies the driver that he/she has forgotten to operate the "empty vehicle" tariff pushbutton and prompts the driver to operate the "vacant vehicle" tariff pushbutton 3d. This can prevent the occurrence of additional charges that would have to be borne by the company.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 2 is a diagram showing an embodiment of the electronic taximeter according to the present invention. In the figure, 1 indicates a frequency change according to the vehicle speed by optical or magnetic means as the vehicle travels. A distance sensor that outputs a signal, 2 a waveform shaping circuit that shapes the signal from the distance sensor 1 and converts it into a pulse, 3 a "Payment" tariff pushbutton 3a, a "20% increase" tariff pushbutton 3b, a "rental trip" ” tariff push button 3c and “empty car” tariff push button 3d, and a tariff signal generation circuit that generates a tariff signal corresponding to each tariff according to the operation of these push buttons; 4 is a pulse from the waveform shaping circuit 2; For example, a microcomputer (hereinafter referred to as "microcomputer") which outputs a tariff display signal by decoding the tariff signal from the tariff signal generation circuit 3 and outputs a tariff display signal by calculating based on the time signal and the toll rate from a means (not shown) is also used. This is a control unit that can be configured by a microcomputer (referred to as μCOM).

Reference numeral 5 denotes a display driver that causes the charge display section 6, tariff display section 7, and index display section 8 to perform predetermined displays based on display signals from the control section 4, and includes a fluorescent display tube;
A fee display section 6 consisting of LEDs, etc., a tariff display section 7,
The index display section 8 is laid out on the panel of the taximeter. Although not shown in the figure, below the tariff display section 7, the above-mentioned "Payment", "20% increase", "Rental charge", etc. Tariff pushbuttons 3a to 3d for "empty cars" are provided respectively, and when these pushbuttons are pressed depending on the business situation,
A tariff signal generation circuit 3 generates a tariff signal.

Reference numeral 10 denotes an alarm circuit, which includes a switching transistor 10a and an electronic buzzer 10b that are turned on and off by the output from the control unit 4. The transistor 10a and the electronic buzzer 10b are controlled in series between the power supply _Vcc and the ground. ing.

In the above configuration, the control unit 4 receives the tariff signal generated by the tariff signal generation unit 3 in response to the pressing operation of the tariff push button, decodes and judges this, outputs a predetermined signal to the display unit driver 5, and outputs a predetermined signal to the display unit driver 5. While driving the display section, an alarm signal is sent to the alarm circuit 10 to generate an alarm.

The alarm signal generated by the control unit 4 is as shown in FIG.
When , it consists of a single negative pulse that is at the "L" level for a certain period of time, and when it is ``20% increase'', it consists of two negative pulses. When such an alarm signal is applied to the alarm circuit 10, the transistor 10a is turned on for a certain period of time for each negative pulse, and the buzzer 10b sounds, and a single tone is emitted when "vacant car", "rental run", or "payment" is made.
At the time of "20% increase", two single tones are generated.
If there is a "30% increase" tariff pushbutton due to the charge system, three single tones can be generated in response to the operation of the pushbutton.

In addition, when the control unit 4 is at a tariff position that should not be present in the running state, for example, "Payment", the controller 4 issues an alarm consisting of 10 negative pulses when it determines the signal from the distance sensor 1 shown in FIG. 3b. A signal is applied to the alarm circuit 10 to generate a single tone ten times in succession to inform the driver that the tariff position is not in the proper position.

The above-mentioned operations are performed based on a flowchart executed by μCOM constituting the control unit 4 according to a predetermined program, and FIG. 4 shows a part of the flowchart.

In FIG. 4, step S1 is a step for determining whether the tariff operation is "20% increase" or not.
If the judgment at that step is YES, proceed to step S.
In step S3, 2 is set in the predetermined area N of the RAM of μCOM, and if NO, 1 is set in step S3. After that, in step S4, one negative pulse is output to the alarm output, and in step S5, one negative pulse is output from the number set in the predetermined area N.
is subtracted to obtain N-1, and in the next step S6 it is determined whether N-1=0.

If N is set to 2 in step S2, N-1=1, and the determination in step S6 is NO, the process returns to step S4 and outputs a negative pulse again, and the remaining pulses are removed in the next step S5. Subtract 1 from the set number again. Through this subtraction, N-1=0, and the determination at step S6 is made.
YES and proceed to the next step. If N is set to 1 in step S3, the determination in step S6 after outputting one negative pulse in step S4 is YES, and the process proceeds to the next step. In other words, tariff operations will increase by 20%.
When , two single tones are generated by two negative pulses; otherwise, one single tone is generated by one negative pulse.

After executing step S6, the process proceeds to step S10 through various steps, where the distance sensor 1 is
It is determined whether the vehicle is in a running state based on the signal from the vehicle. The determination in step S10 is
If YES, then in step S11 it is determined whether the tariff is "payment". When the determination in step S11 is YES, ten negative pulses are generated in the following step S12. The generation of the negative pulse in step S12 is performed in step S12.
4, S5, and S6 can be performed in the same manner as described above. Further, when the determination at steps S10 and S11 is NO, the process proceeds to another step without passing through step S12, and no alarm is generated.

As is clear from the operation of the μCOM described above, the μCOM of the control unit 4 generally responds to the signal generated by the distance sensor 1 in accordance with the travel of the vehicle in response to the operation of the "rental trip" tariff pushbutton 3c. It acts as a calculation unit 4a that calculates the taxi fare based on
0, the tariff detecting means 4b detects the operating state of the "payment" tariff push button 3a, and the traveling detecting means 4c detects the traveling of the vehicle based on the signal from the distance sensor 1.

〔effect〕

As explained above, according to the present invention, "payment"
Since a warning can be issued to the driver when the vehicle is traveling under a tariff condition, it is possible to prompt the driver to correct the tariff position at an early stage, and to prevent additional charges from being incurred due to driving at a wrong tariff position. Therefore,
Troubles with passengers caused by the driver passing on additional charges incurred due to driving at the mistariff position to the next passenger can be prevented.
