It is a flowchart which shows the outline | summary of the process regarding the notice display of the long distance discount performed according to the program stored in ROM built in the controller of the external display apparatus shown in FIG.

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

  FIG. 1 is a block diagram showing a schematic configuration of a taximeter system using a taximeter according to an embodiment of the present invention. The taximeter system shown in FIG. 1 includes a taximeter 10 mounted on a taxi vehicle 1, a printer 20 connected to the taximeter 10, an external display device 30, and a vehicle speed sensor 40.

  The taxi meter 10 calculates and displays a fare including a distance-based fare according to the travel distance of the taxi vehicle 1. The distance-based charge is a total charge of a basic charge that is uniform up to the basic distance and a subsequent charge that is added a number of times according to the distance traveled when the basic distance is exceeded. In the case of a distance-based charge using a time-distance combination system, a subsequent charge is added once every predetermined time while the taxi vehicle 1 is traveling at a predetermined speed (for example, 10 km / h) or less.

  Further, the fare calculated and displayed by the taximeter 10 includes fares to which various discount systems are applied. As an example of a discount system, there is a long-distance discount in which a fixed discount rate is applied when a distance-based fee reaches a certain amount. In this long-distance discount, the total amount of the distance-based charge or a portion exceeding a certain amount is discounted. The taxi meter 10 calculates a discount amount obtained by multiplying the discount target fee by the discount rate, and displays it together with the discounted taxi fare.

  In order to calculate and display the above-mentioned fare, the taximeter 10 includes a display unit 11 for displaying a fare, a discount for a long distance discount, an operation unit 12 for inputting a tariff state, a work area, and temporary storage. A non-volatile RAM 13 provided with a region, a ROM 14 storing programs, a memory card I / O unit 15 for writing and reading data to and from a memory card 50 assigned to a crew member of the taxi vehicle 1, and It has the calculating part (CPU) 16 which controls operation | movement. Further, the taximeter 10 has a time measuring unit (clock IC) 17 that manages the current time.

  The printer 20, the external display device 30, and the vehicle speed sensor 40 are connected to each port (not shown) of the interface (I / F) 18 of the taximeter 10. Although not shown, an actual empty vehicle indicator (super sign) that displays the tariff state of the taxi vehicle 1 is also connected to the interface 18.

  In the RAM 13, a sales data storage unit for generating and storing business data such as a fee for each business, a business kilometer, and business hours is secured. A part of the business data storage unit is used as a work area when the calculation unit 16 calculates a fee based on fee-based data. In addition, a part of the sales data storage unit includes a cumulative index (for example, business number, subsequent number, business kilometer, travel kilometer, number of incoming cars / idling kilometer, travel time, business travel time) by which the arithmetic unit 16 indicates various states of the vehicle. , Business hours, number of long distances, long distance index (discount amount), etc.). This cumulative index is also used for generating the sales data described above.

  In the ROM 14 (corresponding to the storage means in the claims), a setting data storage unit for storing fare pricing data calculated by the taximeter 10 is secured. In addition, when memorizing the fee system that requires the approval of the administrative organization, it is desirable to seal the setting data storage unit or the ROM 14 to prevent falsification.

  The calculation unit 16 calculates a fee and displays the fee on the display unit 11 according to a change in tariff state input from the operation unit 12. The calculation unit 16 calculates a fee by using fee-based data stored in the ROM 14. In addition, the calculation unit 16 refers to the calculation result of the fare, the tariff state input from the operation unit 12, the travel pulse corresponding to the travel speed (travel distance) from the travel sensor (not shown), and the like. Count.

  When the tariff state changes from the payment tariff to the empty tariff by the operation of the operation unit 12 of the taximeter 10, the printer 20 outputs the business data of one operation stored in the RAM 13 that is output via the interface 18. Print out receipt based on. The printer 20 can also perform various report outputs (printouts) based on various data such as cumulative index data output from the taximeter 10 via the interface 18.

  The external display device 30 includes a display unit 31 such as a liquid crystal display and a controller 32. The controller 32 can be constituted by, for example, a microcomputer incorporating a RAM and a ROM (both not shown). The controller 32 receives the cumulative index data from the taximeter 10 via the interface 18 every time a trigger event occurs or periodically. The cumulative index data may be output by the calculation unit 16 of the taximeter 10 without request from the controller 32 or may be requested by the controller 32 and output to the calculation unit 16 of the taximeter 10. And the controller 32 displays the information regarding a long distance discount on the display part 31 based on the data of the input cumulative index.

  The vehicle speed sensor 40 is a sensor provided in the taxi vehicle 1 and outputs a number of pulse signals (travel pulse signals) corresponding to the travel distance in a cycle corresponding to the travel speed. The traveling pulse signal is input to the taximeter 10 via the interface 18.

  Next, in the taximeter system having the above-described configuration, refer to the flowcharts of FIG. 2 and FIG. 3 for an overview of processing related to fare calculation and display performed by the calculation unit 16 of the taximeter 10 according to the program stored in the ROM 14. To explain. In the present embodiment, the payment tariff is a part of the actual vehicle tariff.

  As shown in FIG. 2, the calculation unit 16 first determines whether or not the tariff state of the taximeter 10 has changed from an empty car tariff to an actual car tariff (including a change from an incoming car tariff to an actual car tariff). Is confirmed (step S1). If it has not shifted to the actual vehicle tariff (NO in step S1), the series of processes is terminated.

  In addition, when the actual vehicle tariff is entered (YES in step S1), the calculation unit 16 calculates the distance-based charge for the time-distance combination system (step S3), and displays the calculated distance-based charge on the display unit 11 as the fare. (Step S5). This distance-based fee is calculated based on count values such as the travel distance and travel speed of the taxi vehicle 1 after becoming a real vehicle tariff, and the continuous travel time at a predetermined speed or less. Each count value is counted based on the traveling pulse signal from the vehicle speed sensor 40 and the time measurement content of the time measuring unit 17.

  And the calculating part 16 confirms whether addition of the subsequent charge generate | occur | produced (step S7). If the subsequent charge has not been added (NO in step S7), the calculation unit 16 confirms whether or not the tariff state of the taximeter 10 has shifted from the actual vehicle tariff to the empty vehicle tariff by the operation of the operation unit 12. (Step S9). If it has shifted to an empty car tariff (YES in step S9), the process shifts to step S31 described later, and if it has not shifted to an empty car tariff (NO in step S9), the process returns to step S3.

  If the subsequent charge is added in step S7 (YES), the calculation unit 16 confirms whether or not the distance-based charge is the advance notice amount for the long distance discount (step S11). The amount of advance notice for long-distance discount (equivalent to the reference amount in the claim) is, for example, the start amount of long-distance discount (the fixed amount in the claim when the next charge increases (when the next subsequent charge is added)) The amount of money that reaches

  If it is not the start notice amount (NO in step S11), the process returns to step S3, and if it is the start notice amount (YES in step S11), the calculation unit 16 calculates the distance-based charge of the time distance combination system and the long distance. The remaining travel distance until the start of the discount (at the time of the next subsequent charge addition) is calculated (step S13). The remaining travel distance can be calculated on the basis of the travel distance of the taxi vehicle 1 after the start notice amount of the long distance discount is reached.

  Then, the calculation unit 16 displays the calculated distance-based fare on the display unit 11 as a fare, and displays the calculated remaining travel distance until the start of the long distance discount on the display unit 11 (step S15). ). The discount notice screen may be a message format screen such as “100 meters until starting long-distance discount” as shown in the explanatory diagram of FIG.

  Subsequently, the calculation unit 16 confirms whether or not the subsequent fee has been added (step S17). When the subsequent charge has not been added (NO in step S17), the calculation unit 16 confirms whether or not the tariff state of the taximeter 10 has shifted from the actual vehicle tariff to the empty vehicle tariff by the operation of the operation unit 12. (Step S19). If it has not shifted to the empty car tariff (NO in step S19), the process returns to step S13, and if it has shifted to the empty car tariff (YES in step S19), the process proceeds to step S31.

  In step S17, when the subsequent charge is added (YES), the calculation unit 16 confirms whether or not the distance-based charge is the starting price for the long distance discount (step S21). If it is not the start amount (NO in step S21), the process returns to step S13.

  When the distance fee is the start amount (YES in step S21), as shown in FIG. 3, the calculation unit 16 calculates the distance fee and the distance discount of the time / distance discount system to which the distance discount is applied. The discount amount is calculated (step S23). Then, the calculated distance-based fare is displayed on the display unit 11 as a fare, and the discount amount and the long distance discount are being applied instead of the remaining travel distance until the start of the long distance discount. The “long distance” character shown is displayed on the display unit 11 (step S25).

  Subsequently, the calculation unit 16 confirms whether or not the subsequent fee has been added (step S27). When the subsequent charge is not added (NO in step S27), the calculation unit 16 confirms whether or not the tariff state of the taximeter 10 has shifted from the actual vehicle tariff to the empty vehicle tariff by the operation of the operation unit 12. (Step S29). If it has shifted to an empty car tariff (YES in step S9), the process proceeds to step S31. If it has not shifted to an empty car tariff (NO in step S29), the process returns to step S23.

  In step S9, step S19, and step S31 that proceeds to the case of shifting to an empty tariff (YES) in step S29, as shown in FIG. 2, the calculation unit 16 changes the display unit 11 to display when the vehicle is empty. Then, a series of processing ends.

  As is clear from the above description, in the taximeter 10 of the present embodiment, the process of step S11 in the flowchart of FIG. 2 is a process corresponding to the determination means in the claims. Moreover, in the taximeter 10 of this embodiment, step S13 in FIG. 2, step S15, step S17, and step S21 are the processes corresponding to the discount notice means in a claim.

  Next, in the taximeter system having the above-described configuration, an outline of processing related to the output of the cumulative index performed according to the program stored in the ROM built in the controller 32 of the external display device 30 will be described with reference to the flowchart. To do. The process shown in the flowchart of FIG. 5 is repeatedly executed at regular intervals.

  First, the controller 32 checks whether or not the cumulative index data from the taximeter 10 has been received (step S41). If not received (NO in step S41), the series of processing ends, and if received (YES in step S41), the controller 32 calculates and displays the taxi meter 10 from the received cumulative index. The calculated distance fee is calculated (step S43), and it is confirmed whether or not the calculated distance fee is the advance notice amount of the long distance discount (step S45).

  If it is not the start advance amount (NO in step S45), the process proceeds to step S51, which will be described later. If it is the start advance amount (YES in step S45), the controller 32 starts the long distance discount (addition of the next subsequent fee). The remaining travel distance up to (hour) is calculated (step S47). This remaining travel distance is equal to or less than the travel distance, travel speed, and predetermined speed of the taxi vehicle 1 after the far-off discount start notice amount is reached, in the same manner as the calculation unit 16 of the taximeter 10 calculates the remaining travel distance. Can be calculated based on the continuous running time. Therefore, the controller 32 uses the cumulative index from the taximeter 10 to calculate the remaining travel distance.

  Then, the controller 32 displays the calculated remaining travel distance until the start of the long distance discount on the display unit 31 as a discount notice screen (step S49), and ends the series of processes. Similar to the discount notice screen displayed on the display unit 11 of the taximeter 10, this discount notice screen is, for example, a message-format screen such as “100 meters until starting long-distance discount” as shown in the explanatory diagram of FIG. be able to.

  Further, in step S51, which proceeds to the case where the distance-based fee calculated in step S45 is not the long-distance discount start notice amount (NO), the controller 32 confirms whether or not the distance-based fee is the long-distance discount start amount. . If it is not the start amount (NO in step S51), the series of processing ends, and if it is the start amount (YES in step S51), the controller 32 causes the remaining travel until the start of the long distance discount on the display unit 31. The distance display is terminated (step S53), and the series of processes is terminated.

  As is clear from the above description, in the external display device 30 of the present embodiment, the process of step S45 in the flowchart of FIG. 5 is a process corresponding to the determination means in the claims. Further, in the external display device 30 of the present embodiment, step S47, step S49, and step S51 in FIG. 5 are processes corresponding to the discount notice means in the claims.

  According to the taximeter 10 and the external display device 30 of the present embodiment having the above-described configuration, the distance-based fee reaches the start notice amount that becomes the start amount of the long distance discount when the subsequent fee is added once more. Then, on the display units 11 and 31 of the taximeter 10 and the external display device 30, the remaining travel distance until the start of the long distance discount is displayed as a discount notice screen in a message format such as “100 m until the long distance discount starts”. The configuration is as follows.

  For this reason, in the stage before the long distance discount is started, the long distance discount will be started soon by the display of the discount notice screen on the display units 11 and 31 of the taximeter 10 and the external display device 30. It can be made easier to recognize before starting the distance discount.

  In addition, the external display device 30 displays a discount notice screen on the display unit 31 based on the cumulative index data output from the taximeter 10. For this reason, it is possible to connect the external display device 30 to the taximeter 10 by using the existing interface 18 for connecting the printer 20 or the like, which is a partner to which the cumulative index data is output, as it is.

  In addition, instead of the remaining travel distance until the start of the long distance discount, a bar having a length or number serving as a guide for the remaining travel distance is displayed on the taxi meter 10 or the display units 11 and 31 of the external display device 30 as a discount notice screen. You may make it display. However, if the remaining travel distance is displayed as a numerical value as in the present embodiment, it is advantageous that the remaining distance until the start of the long distance discount can be specifically recognized by the numerical value.

  The present invention is suitable for use in taximeters that calculate and display taxi fares and external display devices that are connected to the taximeter.
