DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for displaying, on a taxi meter, a fare calculated based on a normal fare system, and discounts and surcharges for the fare.

[0002]

2. Description of the Related Art Conventionally, a taxi meter generally calculates and displays a normal fare based on a traveling pulse or a conventional fare or a late-night early-morning surcharge, and employs a fixed pick-up vehicle fare system. A taxi meter for a certain area is configured to display the fare fare separately from the normal fare.

In recent years, in the taxi industry,
A new tariff system has been introduced in addition to the conventional fare system and the late-morning and early-morning surcharge system, and movements have begun to aim at improving passenger services and revitalizing competition with competitors.

[0004] The new fare system includes, for example, a time-specified reservation fee to be added to a fare when a taxi is reserved by designating a time, or exceeding a standard time from arrival at a reservation destination until passengers board. When a waiting time occurs, there is an additional charge system such as a wireless waiting charge that is added to the fare according to the excess time. This additional fare system is a fare system in which the amount is fixed or the amount is determined according to the elapsed time. Therefore, even if the normal fare before the taxi arrives at the destination is undecided, the time is not determined. The amount of the designated reservation fee or wireless waiting fee is fixed.

[0005] As a new fare system other than the additional fare system, when the actual required time is shorter than the standard required time set in accordance with the normal fare, the normal fare is set according to the time difference. There are discounted rates such as a high-speed travel discount that is discounted and a long-distance discount that discounts, at a fixed rate, a fee that exceeds the reference amount of the normal fare when the normal fare exceeds a certain reference amount. Unlike the additional fare system, the discount fare system is a fare system in which the amount is determined based on a rate relative to the normal fare, so that the discount is available only after the taxi arrives at the destination and the amount of the normal fare is determined. The amount of the subsequent fare is not fixed.

When the additional fare system and the discount fare system are applied, the final fare to be collected when the passenger gets off the vehicle is calculated by multiplying the normal fare by the discount rate of the discount fare system.
The discount fare calculated in this way and the normal fare are added together (the discount fare is subtracted from the normal fare), and the calculated fare fare and the time-specified reservation fee or the wireless waiting fee specified in the additional fare system are added. And the like and the above-mentioned fare charge is further added up.

[0007] Therefore, when constructing a taxi meter compatible with the above-mentioned various new fare systems, the amount of money such as the pick-up fee, the time-specified reservation fee, and the wireless waiting fee is independent of the normal fare. The fixed fare is displayed on the taxi meter separately from the normal fare during taxi driving, and when the taxi arrives at the destination and the passenger sets the tariff by using the taxi meter as a tariff, each of the above is settled. Ideally, the final ride fare obtained by performing the summing process is displayed.

[0008]

However, when it is necessary to know how much the final fare at the present time will be, as an intermediate course, the summation processing and the accompanying normal fare and fare fare are separated. If switching from the display to the display of the final fare is performed at the time of traveling before arriving at the destination, if the subsequent travel increases the normal fare and the displayed final fare increases by that amount In addition, it is not possible to see at a glance the details of the amount of each of the normal boarding fee, the pick-up fee, the designated time reservation fee, the wireless waiting fee, and the like by the display of the taxi meter. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a final fare obtained by adding various fares generated by various fares and a normal fare, not only after arrival at the destination, but also , Calculated at any time during traveling,
Can be displayed, and with subsequent changes in the normal fare,
An object of the present invention is to provide a taxi meter that can return the display to a state before the summation.

The operation information collecting device 5 is connected via the. As shown in the memory area map in FIG. 8, the RAM 323b has a data area for storing various data and a work area used for various processing operations. The data area is provided with a fee-based data area and an index data area. The work area includes a counter area, buffer areas a, b, c, and d, a timer area a, b, a calculation area, a fare register, a fixed fare register, a total fare register, and a flag area a, b. ing. The ROM 323c stores a control program for causing the CPU 323a to perform various processing operations.

The E ² PROM 327 stores the data of the charge system of each unit corresponding to each of the buttons 307 to 319, and is provided inside the charge display device 3.

Next, the processing performed by the CPU 323a in accordance with the control program stored in the ROM 323c will be described with reference to the flowcharts of FIGS. The charge display device 3 is turned on and the microcomputer 323 is turned on.
Are started and the program starts, as shown in FIG. 9, the CPU 323a performs initialization (step S
1). In this initial setting, the charge system data of each unit corresponding to each of the buttons 307 to 319 is read from the E ² PROM 327, stored in the charge system data area of the RAM 323b, and stored in the flag areas a and b of the RAM 323b. Fa and Fb are set to 0, and the empty lamp 320a is turned on.

The flag Fa in the flag area a is set to "1" when the total fare obtained by adding the fixed fare or the hourly fares 1 and 2 to the fare is displayed on the second fare display section 305, Is displayed on the second charge display unit 305, and fixed charges and hourly charges 1 and 2 are displayed on the first charge display unit 303. The flag Fb of the flag area b is set to “1” when the extra or discount unit tariff is set by operating the unit tariff buttons 313 to 319, and is set to “1” when the extra or discount unit tariff is not set at all. 0 ”. At the time of this initial setting, both the taxi meter main body 1 and the fee display device 3 are in an empty car tariff state.

Next, the counter value C in the counter area of the RAM 323b for counting the number of times of operation of the total button 321 in the empty car tariff state of the taxi meter main body 1 and the toll display device 3 is reset to zero (step S3).
Subsequently, it is confirmed whether or not the total button 321 has been operated (step S5). If the total button 321 has not been operated (N in step S5), the process jumps to step S27 described later, and if the total button 321 has been operated (step S5). Y) and then
The counter value C is incremented by "1" (step S7). The counter value C is an index data pair (a total of seven sets, item numbers 26 to 39 in FIG. 6) in which one set of index data of the number of applications of each unit tariff and the applicable amount is included in the system data of FIG. It corresponds to the number, and is incremented in order from “1” to “7” except at the time of reset.

Then, index data in the taxi meter body 1 (item numbers 4 to 11, 1 in FIG.
3, 14, 16 and 17) are output (step S9), the index data output from the taxi meter body 1 is received (step S11), and the index data is processed and stored in the buffer area a of the RAM 323b. It is stored (step S13). However, in this case, the taxi meter body 1 is still an empty car tariff, and there is still no business operation to which the extra and discount unit tariffs corresponding to the buttons 307 to 319 are applied, so that the index data after processing is the same as the index data before processing. Is the same.

Next, the 15-second timer in the timer area a of the RAM 323b is started (step S15), and the number of times of application of the unit tariff corresponding to the counter C obtained by processing the index data and the exponent of the amount of application are calculated. The first and second fee display sections 303 and 305 are separately displayed simultaneously (step S17). Thereafter, it is determined whether or not the total button 321 has been operated again (step S19). If the total button 321 has been operated (Y in step S19), the process returns to step S7. If the total button 321 has not been operated (N in step S19). Then, it is determined whether or not the 15-second timer has expired (step S21). If the 15-second timer has not expired (N in step S21), the process returns to step S19. If the time has expired (Y in step S21), the first and second charge display sections 30 are displayed.
The display of the exponent of 3,305 is stopped (step S23), and the counter value C is reset to zero (step S2).

Following step S25 or step S25
In step S27, which is a jump destination when the total button 321 is not operated in step 5, the taxi meter main unit 1
It is determined whether or not the business signal 1A is detected. If the sales signal 1A is detected (Y in step S27), the taxi meter main body 1 jumps to step S49 described below as having entered the business tariff, and if not detected (N in step S27), the taxi meter Assuming that the main body 1 remains as an empty tariff, unit tariff buttons 307 to 311 for fixed charges and hourly charges 1 and 2 are next.
Is checked (step S29).

If the unit tariff buttons 307 to 311 are operated (Y in step S29), the empty lamp 3
20a is turned off (step S31), the fixed lamp 307a or the time lamp 309a is turned on (step S33), and the fixed fee and the hourly fee 1 and 2 determined by the fee system in the E ² PROM 327 are set to the first amount. Charge display part 3
03 is displayed (step S35). Subsequently, of the index data of the buffer area a, the fixed fee corresponding to the unit tariff buttons 307 to 311 whose operations have been detected in step S29, or the exponent of the hourly tariff 1, 2 unit tariffs are added (step S37). The sales signal 3A is output (step S39), and it is confirmed whether or not the operation of the empty car tariff button 320 is detected (step S41).

When the operation of the empty car tariff button 320 is confirmed (Y in step S41), the process jumps to step S149, and when the operation is not confirmed (N in step S41).
It returns to step S5. When the process returns to step S5 from step S41 and reaches step S17, the first fee display unit 303 displays the fixed fee currently displayed or the counter C in place of the hourly fee 1 or 2 instead of the amount. The number of application of the unit tariff to be performed is displayed, and then, in step S23, the display of the first fee display unit 303 is changed from the number of application of the unit tariff corresponding to the counter C to the fixed fee displayed at the time of step S15, or The display contents are returned to the hourly charge 1 and 2.

On the other hand, if the unit tariff buttons 307 to 311 are not operated in step S29 (N),
The power supply from the stabilizing power supply 13 is stopped and the fee display device 3
