JP4747012B2 - Rent fare meter and setting change recording medium - Google Patents

Description

The present invention provides a program execution means that is mounted on a vehicle such as a taxi vehicle or an accompanying vehicle at the time of driving agency, and that functions to calculate a rent fee according to the distance traveled by the program. built-in Chinhashi rates meter, and those concerning the setting change recording medium body used to change the functionality of該賃run fee meter.

  Conventionally, as this type of meter, there is a taxi meter that calculates and sequentially displays a rental fee according to the travel distance mounted on a taxi vehicle based on an approved fee system. For example, a taxi meter captures and processes a distance signal whose period changes according to axle rotation generated when a distance sensor on the vehicle body side inputs rotation according to axle rotation from a part of the transmission. Is calculated by In addition, the fee system is for ensuring the convenience and reliability of the user while ensuring the clarity of the rental fee.

  However, as a taxi meter, to calculate the rent fee according to the mileage etc. even if the measurement of the mileage that is the basis for calculating the rent fee is not accurate or the measured mileage is accurate If the tariff system applied to is not as approved, taxi meter reliability will be impaired.

  Therefore, in order to use taximeters that operate under the newly approved fare system, taxi operators have traditionally inspected the performance and notation of the taximeter itself after it has been manufactured and shipped. Each test that proves that it passed both inspections (head inspection) and inspections (equipment inspection) of mileage error, notation, etc. (equipment inspection) with taxi meter body mounted on taxi vehicle Seals (head inspection seals and device inspection seals) had to be made respectively. These seals are effective in eliminating the fraud of tampering with mileage measurement and tolling.

  Against this background, conventionally, when the fare system has been revised, a taxi meter already mounted on the taxi vehicle is removed from the taxi vehicle, and an electrically rewritable nonvolatile memory such as an EEPROM inside the taxi vehicle By changing the data and programs related to the charge system stored in the storage means that can hold the stored contents without backup power supply, the charge calculation processing by the new charge system can be performed, and again It is attached to a taxi vehicle and reused. This is because the change work is related to the inside of the taximeter body, and it is assumed that the taximeter manufacturer works.

  In this change work by the taximeter manufacturer, the data and programs related to the toll system to be changed were memorized by using the memory card reader / writer (RW) that the taximeter provided for taxi vehicle operation records. The memory card is inserted into the R / W card insertion slot and read to change data related to the fee system and the program already stored in the storage means. In the case of taximeters not equipped with R / W, a connector for connecting a setting device for changing data and programs is provided, and the change data stored in the memory in the setting device connected via the connector is provided. Data and programs are sent and read from the setting device side, and data and programs related to the fee system already stored in the storage means are changed.

  For this reason, what has to be done with the revision of the fare system is that the taxi meter has been removed from the taxi vehicle in order to carry out the work, despite the setting changes accompanying the revision of the fare system. Then, when the taxi meter is attached to the original taxi vehicle after performing the change work, there is a problem accompanied by troublesome work in which both the head test and the device test must be performed again.

  Therefore, in the past, even if the taxi operator can change the data and programs related to the fee system on behalf of the taximeter manufacturer without removing the taxi meter from the taxi vehicle, Have been proposed that can be fully accommodated.

  In this proposed taximeter, there is an operation switch that cannot be operated by the shield plate that is always sealed, and only when the operation switch is operated after the seal is released, the work can be changed with a memory card or setting device. It is comprised so that. When the operating fee system is revised, the taxi operator receives a loan from the taximeter manufacturer for the memory card or setting device for revision work, unlocks the shielding plate and operates the operation switch. After the change work is completed using the memory card or setting device, the shield plate is sealed again after the inspection equivalent to the device inspection, and the operation switch cannot be operated. Therefore, falsification of the fee system is prevented (see, for example, Patent Document 1).

With this proposed taximeter, it is not necessary to remove the taximeter from the taxi vehicle when the tariff system is revised, so the taxi operator can make changes while the taximeter is mounted on the taxi vehicle. The operator only has to lend a revised memory card or setting device to the taxi operator, and the inspection for the resealing of the shielding plate and the sealing work based on the result will be performed. Since the inspection and the sealing work performed based on the result are not necessary, the work performed in accordance with the revision of the fee system is greatly reduced.
JP 2004-46563 A

  However, in the proposed taximeter, although the work to be done with the revision of the fee system has been greatly reduced, inspection and sealing work are still required after the change work when the fee system is revised.

  Therefore, taxis that enable operations that can fully cope with tampering without having to perform inspections and sealing work after changing the functions of taximeters in accordance with changes in data and programs related to fare systems. As a meter, it is determined whether the memory card inserted into the card insertion slot of the memory card R / W or the setting device connected to the connector is genuine for revision, and only when it is authentic In addition to providing a function to perform change processing, the device number for identifying the taximeter and the vehicle body number for identifying the taxi vehicle on which the taximeter is mounted are stored in advance, and the taxi meter charges are displayed during the change processing. It is conceivable to have a function of transmitting to the setting device for display on the display device or to display on the display device of the setting device.

  In such a taximeter, when the change work is performed, the device number as the specific information for specifying the taximeter on the display unit of the taximeter or the setting device and the specific information for specifying the vehicle on which the taximeter is mounted are used. Since the body number is displayed, a record of the displayed equipment number and body number is taken, and this record and a database showing the correspondence between the equipment number and the body number stored in advance as management data By collating, it becomes possible to check whether the change work has been done for things other than taximeters that should be changed in setting information such as data and programs related to the fee system, and the loaned memory card and setting device When diverted to something other than taximeters that should be changed, the records and database are inconsistent. Since seen, it can be prevented from being diverted to the alteration of the fee-based.

  However, in this taxi meter, the fare system change work, which involves recording the displayed device number and body number, is often done at night after the taxi vehicle arrives. There is a high possibility that a mistake will occur in the recording to be performed. If there is a mistake in the record, there will be a discrepancy between the record and the database, but it is determined whether the cause is due to a record mistake or a change work for a taximeter other than the taximeter to be changed. It cannot be said that it is sufficient to prevent diversion of the tariff system.

  In addition, what has been described above has the same function as a taxi meter, and includes a toll meter mounted on an accompanying vehicle at the time of driving agency, and calculates a toll fee according to the distance traveled by the program. Occurs in a rental fare meter with built-in program execution means that realizes the function to perform.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing a schematic configuration of a taxi meter which is an embodiment of a rental charge meter according to the present invention. In FIG. 2, the taximeter includes a microcomputer (hereinafter abbreviated as MCOM) 100 that operates according to a program, and a display unit 110, an operation unit 120, and a signal input / output (I / O) unit connected to the MCOM 100. 130 and a data input / output (I / O) unit 140, which are mounted on a taxi vehicle (not shown) and used.

  The MCOM 100 includes a central processing unit (CPU) 101, a ROM 102 which is a read-only memory, a RAM 103 which is a readable / writable memory, an EEPROM 104 which is a non-volatile memory rewritable to an electric device, and generates data for the year, month, day and time. What is called a one-chip microcomputer that incorporates a calendar unit 105 and a bus line for interconnecting these with the CPU 101 is preferably used.

  The display unit 110 includes a display panel such as a liquid crystal display panel, and a driver that drives the display panel based on display data from the CPU 101, and performs various displays in addition to the display of the rent price. Although not shown in detail, the operation unit 120 includes an option button that can be used as an arbitrary operation button depending on settings in addition to a dedicated operation button such as a tariff operation button essential for a taximeter. Is input to the CPU 101.

  The signal input / output (I / O) unit 130 is an interface for inputting and outputting signals, and a travel sensor (not shown) provided in the taxi vehicle is generated as an input signal according to the travel of the taxi vehicle. A travel signal or the like whose cycle changes according to the vehicle speed is input and taken into the CPU 101. As an output signal, a sign signal or the like is output from the CPU 101 for displaying the tariff state set by the CPU 101 by the tariff operation on a tariff display (not shown) provided in the taxi vehicle and notifying the outside.

  The data input / output (I / O) unit 140 is an interface for inputting and outputting digital data. In the data I / O unit 140, a receipt amount based on the rental fee displayed on the display unit 110 based on the print data output from the CPU 101, and an issue based on the date / time data generated by the calendar unit 105. In addition to the printer 150 that prints the date and the like and issues a receipt, the data reading to the memory card is performed in order to collect the operation record data for grasping the operation status of the taxi vehicle to the memory card as a portable recording medium. A memory card reader / writer (R / W) 160 for writing data is connected to the connector. For example, RS-23C communication is performed between the printer 150 and the memory card R / W 160 and the CPU 101 to exchange write data and read data.

  The CPU 101 operates as a program execution unit that operates according to a program and performs various processes. Typically, the CPU 101 refers to fee system information related to a predetermined fee system, and calculates a rental fee according to the travel distance of the vehicle. Works as a fare calculation means. Even if the CPU 101 only works as a typical rent fare calculation means, the fare information includes the basic distance, the basic charge up to the basic distance, the meter rising distance after exceeding the basic distance, and the subsequent charges for each meter rising distance. Necessary as fare information, and as a program, a function for measuring that the mileage is a basic distance, and the distance traveled based on the mileage signal input to the signal I / O unit 130, and the referenced fare information and In order to realize the function of calculating the rental fee based on the measured distance, a function is required.

  In addition, for example, when calculating the rent fee not only for distance but also for elapsed time, change to add elapsed time corresponding to the distance after basic distance travel as pricing information For the program information, the program also has a function to measure the time after driving for the basic distance, and when the measured time reaches the elapsed time before the distance running, It is necessary to make a change to add a function that increases the charge.

  Contrary to the above, when the renting fee calculation means is initially configured to calculate the renting fee taking into account the elapsed time, when changing to not take into account the elapsed time Needs to be changed to delete the elapsed time from the rate information and delete the corresponding function from the program.

  As described above, there is a case where not only the fee system information and the program are changed, but also only one of them is changed. For example, the function of the rental charge calculation means is not changed, and when the basic charge or the subsequent charge is increased, it can be dealt with by revising only the charge system information. On the contrary, when adding a function to calculate the late night premium without changing the pricing system information, the premium is calculated based on the rental charge calculated by the rental charge calculation means. This is the case when a change is made to add a program to realize a function for calculating the rent by adding the rent to the original rent.

  In any case, the setting information can be electrically rewritten so that addition, deletion, revision, etc. can be made to preset information (hereinafter referred to as setting information) such as program and fee information. It is written and stored in the EEPROM 104 as a nonvolatile storage means for storing.

  As shown in FIG. 3, storage of the fee information and program in the EEPROM 104 is performed by dividing the storage area into a fee information storage area 104b and a program storage area 104c. Initially, a considerable amount of unrecorded areas 104b2 and 104c2 are secured in addition to the recorded areas 104b1 and 104c1, respectively, so that the addition of programs can be accommodated.

  As shown in FIG. 3, the EEPROM 104 includes, as shown in FIG. 3, device information that specifies a taximeter, for example, device information including a device number, and vehicle information that includes a vehicle number on which the taximeter is mounted, for example. It is used for a specific information storage area as specific information storage means for storing the specific information. The reason why the specific information is stored in the EEPROM 104 is known in advance for the device number, but the vehicle information is fixed when the taximeter is mounted on the taxi vehicle and cannot be known before that. This is because it is necessary to be written by the writing means after this. The specific information is written into the EEPROM 104 by, for example, disconnecting the printer 150 connected to the connector and connecting a setting device 170 having an operation unit and a display unit instead, and then operating the key of the operation unit. This can be done by inputting specific information.

  The CPU 101 also externally outputs setting change information for changing the setting information including the fee system information and the program stored in the EEPROM 104 when the taximeter is switched from the normal mode in which the taximeter operates normally to the change mode. It functions as a setting information changing means that changes the setting information acquired from the storage means and stored in the EEPROM 104 based on the acquired setting change information.

  Switching from the normal mode of the taximeter to the change mode is easy for anyone by, for example, performing simultaneous operation of two buttons that are not operated together in normal operation among the operation buttons of the operation unit. It is not possible to switch modes, and erroneous operations can be prevented.

  In the present embodiment, when the CPU 101 is switched to the change mode, the function of causing the memory card R / W 160 provided for the taximeter to collect the operation record data in the memory card to read and send the data from the memory card. Is given. As a result, a memory card, which is a portable recording medium, is used as the external storage means, and the setting change memory card MC storing the setting change information is inserted into the memory card R / W160 before switching to the change mode. Thus, the setting change information can be acquired from the external storage means.

  The CPU 101 temporarily stores the acquired setting change information in the work area in the RAM 103. Based on the stored setting change information, the setting information already stored in the EEPROM 104 is electrically rewritten and changed to function as setting information changing means. As described above, the setting change information includes the program change information and the fee system change information, but the acquired setting change information may be either or both. In any case, the presence / absence of the acquired setting change information is determined, and the charge information and programs in the areas 104b and 104c in the EEPROM 104 are rewritten and changed in a predetermined order, for example, charge information and program.

  The CPU 101 serving as setting information changing means acquires fee system change information for changing the fee system information stored as setting information in the EEPROM 104, and is stored in the EEPROM 104 based on the acquired fee system change information. The fee information changing means for changing the fee information and the program change information for changing the program stored as the setting information in the EEPROM 104 are acquired, and stored in the EEPROM 104 based on the acquired program change information. It works as a program change means to change the program.

  Information about the pricing system is not so large as the amount of information, so it is possible to revise, delete, and add or change the pricing system information by rewriting all existing information. Is also possible. Regarding the program, the program described in relation to the existing program can be changed by revising, deleting, and adding functions to the existing program by writing the program in the unrecorded area.

  Of course, there are parts of the program that are not affected by revisions, deletions, and additions of functions, so when you change the program, store the program separately in parts that may be affected As for programs stored as potentially affected, it is possible to revise, delete, and add changes by rewriting the entire program including the existing program. In this case, if the amount of information rewriting increases and it takes time, it is better to make changes with partial correction.However, if rewriting is possible and the rewriting time is not so long, all Since it is possible to remove unnecessary programs without leaving unnecessary programs, it is preferable to reduce the unrecorded area prepared in advance in the EEPROM 104.

  Thereafter, the CPU 101 reads out the specific information stored in the EEPROM 104, adds the date / time data generated by the calendar unit 105 to the read out specific information, and stores the information as write information to the setting change memory card MC. Output to the card R · W160.

  Note that the setting change memory card MC as the setting change recording medium used for changing the function of the rental charge meter indicates that the memory card is for setting change as shown in FIG. First read area MC1 where the card identification information is heard, and setting change information (charge system change information, program change information) for changing the setting information (charge system information, program change) stored in EEPROM 104 is read data Is output to the memory card R / W 160 each time the setting information stored in the EEPROM 104 is changed by the second read area MC2 stored as, and the setting change information stored in the read area MC2. A writing area MC3 for storing specific information (device information, vehicle body information) with date, month, day, hour and minute data added as write data To.

  The memory card R / W 160 in which the above-described setting change memory card MC is detachably loaded reads the card identification information and the setting change information from the first and second read areas MC1 and MC2 of the memory card MC, respectively. It functions as a read / write means for writing write information into the write area MC3.

  Details of the operation of the taximeter outlined above will be described below with reference to the flowchart of FIG. 5 showing the processing performed by the CPU 101 in accordance with the program.

  The CPU 101 starts its operation when the power is turned on, and performs a normal mode operation as a taximeter while referring to the pricing information stored in the EEPROM 104 according to the program stored in the ROM 102 or the EEPROM 104. For example, when an actual vehicle tariff button that monitors the operation of the tariff button of the operation unit 120 and instructs the start of renting is operated, the fare corresponding to the mileage of the vehicle is referred to by referring to the fare information related to the predetermined fare system. A normal process is performed in which the fare is calculated, and the fare is displayed on the display unit 110 based on the calculated rent, or the receipt 150 is printed on the printer 150 based on the rent data ( Step S1).

  When the change mode switching operation is performed by two specific operation buttons of the operation unit 120 during the normal process (when step S2 is YES), the CPU 101 switches the operation mode to the change mode, and the memory card R It is determined whether or not a memory card is attached to W160 (step S3). When the CPU 101 determines that a memory card is attached (YES in step S3), the CPU 101 reads and obtains card identification information from the first read area MC1 of the attached memory card. It is determined from the identification information whether the memory card is for setting change (step S4). If the result of determination is not for changing settings (NO in step S4), a message prompting the user to insert the correct card is displayed on the display unit 110 (step S5), and the correct card is awaited.

  When a setting change card is inserted (YES in step S4), the CPU 101 reads and acquires setting change information from the second reading area MC2 (step S6), and acquires the acquired setting change information. Is stored in the work area of the RAM 103 (step S7). Thereafter, when there is fee change information in the setting change information stored in the RAM 103 (step S8 is YES), the CPU 101 changes the fee information stored in the EEPROM 104 based on this fee change information. (Step S9). Then, the change of the fee information based on all the fee information is completed (when step S8 is NO), and then the program change information is present in the setting change information (when step S10 is YES). Based on this program change information, the program stored in the EEPROM 104 is changed (step S11). Then, when the program change based on all the program change information is completed (when step S10 is NO), the specific information stored in the EEPROM 104 is read (step S12), and the calendar portion is added to the read specific information. The data for the year, month, day, and hour in which 105 is generated is added (step S13) and output to the memory card R / W 160 as write information for the setting change memory card MC (step S14). The data is written in the MC write area MC3.

  At this time, by displaying on the display unit 110 that the setting information changing operation has been completed, the operator can be notified of the completion of the operation. When the setting change memory card MC is removed from the memory card R / W 160 by the operator (YES in step S15), the operation of the taximeter is switched from the change mode to the original normal mode.

  As described above, when the setting information stored in the EEPROM 104 is changed based on the setting change information stored in the setting change memory card MC, the device number of the taximeter that has completed the change work, and the work is completed. The specific information consisting of the body number of the taxi vehicle on which the taximeter is mounted and the changed year / month / date / time data are written and collected in the setting change memory card MC.

  Therefore, the information collected in this memory card is read by the management device of the taximeter manufacturer that lent the memory card for setting change, and the taximeter with the changed setting information and the taxi vehicle equipped with it are captured, It is possible to manage whether or not a change operation has been performed for a taximeter that should not be changed in the setting information by referring to a database including the taximeter and the taxi vehicle to be changed. Further, the number of taximeters whose setting information has been changed by the memory card can be captured by the number of specific information collected by the setting change memory card MC. This can be effectively used to calculate the price when the price is determined according to the number of taximeters whose setting information has been changed.

  In the embodiment described above, the memory card R / W160 for operation recording attached to the taximeter is used as the external storage means, and the memory card, which is a portable recording medium that is detachably attached to the taximeter, is used. Although what was utilized was demonstrated, in the case of the taximeter which does not have the memory card R * W160, the setting device 170 mentioned above for writing specific information in the EEPROM104 can be used.

  In this case, the setting device 170 is provided with an EEPROM that works as a nonvolatile storage means like the memory card and the writing area MC3, and the same data as the setting change memory card is written in these areas. When the taximeter is switched to the change mode, the printer 150 is disconnected and the setting device 170 is connected instead, so that the setting change memory card MC mounted on the memory card R / W 160 is used as the external storage means. The same change work as that performed using the EEPROM in the setting device 170 can be performed as an external storage means.

  In the setting change method for changing the setting information of the taximeter by the taximeter having the above-described configuration and the setting change memory card MC, the taxi mounted on the taxi vehicle is one of the program execution means for performing various processes. Setting information for at least one of a program for operating the built-in fare calculation means and a fare information related to a predetermined fare system that the rent fare calculation means refers to when calculating the rent charge according to the travel distance of the vehicle Is stored in the EEPROM so that it can be electrically rewritten and changed, and specific information including device information for specifying the taximeter and vehicle body information for specifying the taxi vehicle on which the ximeter is mounted is stored in the EEPROM. When the setting information is changed, the setting change information is acquired from the setting change memory card MC, and the setting information stored in the EEPROM is changed based on the acquired setting change information. Thereafter, the specific information stored in advance in the EEPROM is read out and output to the output means as write information for the setting change memory card. When setting changes are made in this way, accurate specific information about taxi meters that have undergone setting changes and taxi vehicles equipped with them is troublesome in the setting change memory card that is the external storage means used for setting change work. It is automatically collected without work, and it is possible to accurately grasp taximeters whose settings have been changed, and to prevent taximeter settings that should not be changed, that is, taximeter tampering.

  In the above-described embodiment, the case where the fare meter is a taxi meter has been described. However, the present invention is mounted on a companion vehicle when the fare varies depending on the travel distance of the companion vehicle at the time of driving agency, for example. It can also be applied to a toll meter.
