Description

  The present invention relates to a passenger terminal for taxi that displays information related to a taxi fare in real time and can settle the taxi fare by electronic money charged in electronic money media that can be read by RFID (Radio Frequency Identification) technology.

  As an invention in which a taxi fare can be paid with a prepaid card, for example, there is an invention described in Patent Document 1. That is, in Patent Document 1, the balance information is obtained from the prepaid card by reading with a card reader / writer, the deposit amount is subtracted from this amount, the fee amount is taken from the taximeter, and the fee data is subtracted from the deposit amount. An invention is described in which a monetary amount is obtained and a travelable distance based on the remaining amount is obtained and displayed (paragraphs 0024 to 0025 of Patent Document 1). An object of the present invention is to “successfully know how much use is possible within the range of the amount when the amount payable for the use is specified” (patent Reference 1, paragraph 0005).

  On the other hand, there is an invention described in Patent Document 2 as an invention in which a taxi fare can be paid with electronic money charged in an IC card readable by RFID technology. According to the present invention, when a passenger 3 carrying an IC card gets into the taxi 1, a reader 4 installed in the taxi 1 activates the IC card 7 via the antenna 5 to communicate with the IC card 7, The destination and balance information stored in the IC card 7 is displayed on the display device 4A .... (Omitted) ... After arriving at the destination, the information on the boarding fare is passed from the charge indicator 8 to the reader 4 via the cable 9. The reader 4 then subtracts the fare from the balance of the IC card 7 via the antenna 5 and writes the taxi usage status ”(paragraph 0017 of Patent Document 2).

Japanese Patent Laid-Open No. 11-312258 JP 09-128571 A

  Assuming that taxi fares are paid with electronic money charged to electronic money media readable by RFID technology, one of the concerns for passengers who are taxi users is that taxi fares are withdrawn from electronic money media. It will be the balance of the electronic money remaining in the event of a loss. On the other hand, in Patent Document 1, although the taxi fare payment medium is a prepaid card and is not electronic money charged to electronic money media readable by RFID technology, the distance traveled by the remaining amount is obtained. It is described that this is displayed. However, the invention described in Patent Document 1 only displays the travelable distance based on the remaining amount, and cannot notify the passenger of the remaining electronic money remaining when the taxi fare is withdrawn from the electronic money media. . Therefore, the passenger cannot know the balance of electronic money remaining when the taxi fare is withdrawn from the electronic money media that changes as the taxi operates. This is the first problem.

  The second challenge is to determine which electronic money media will be used for the balance of electronic money remaining when a taxi fare is deducted from electronic money media that changes with taxi operation when the passenger has multiple electronic money media. I want to be able to inform the passengers even if I target.

  The third problem is that if the taxi fare is paid with electronic money charged to electronic money media that can be read by RFID technology, the technique described in Patent Document 2 is used to give passengers a sense of security. It is a problem that is difficult. That is, Patent Document 2 describes that information stored in an RFID chip can be read only when a passenger carrying an IC card equipped with the RFID chip gets on a taxi (see paragraph 0017 of Patent Document 1). . From this description, the RFID technology described in Patent Document 1 seems to have a communicable distance of at least about 1 m. This point is described in Example 3 in paragraph 0023 of Patent Document 1, that is, when a plurality of passengers who have an IC card equipped with an RFID chip board a taxi, information is received from the plurality of IC cards. It will be clear from the statement that it will be acquired. For this reason, the problem of the invention described in Patent Document 2 is that the information stored in the RFID chip is read just by getting on the taxi by the person who has the IC card equipped with the RFID chip, and the passenger knows it. Taxi fares will be withdrawn. This makes it difficult to give passengers a sense of security.

  It is an object of the present invention to provide an electronic device that remains when a taxi fare is withdrawn from an electronic money medium that changes as a taxi operates when paying a taxi fare with electronic money charged in electronic money media readable by RFID technology. It is to be able to inform passengers of the balance of money.

  According to another aspect of the present invention, when a passenger possesses a plurality of electronic money media, the taxi fare is paid with electronic money charged to electronic money media readable by RFID technology. It is to be able to notify passengers of any electronic money media remaining in the electronic money remaining when taxi fares are withdrawn from the changing electronic money media.

  Yet another object of the present invention is to provide passengers with a sense of security when paying taxi fares with electronic money charged to electronic money media readable by RFID technology.

  The present invention enables non-contact communication via an antenna between an information processing unit that performs an information processing function, a display that displays information, and an RFID chip that is provided in an electronic money medium and can be charged with electronic money. An RFID reader / writer that limits the distance range of the non-contact communication to a distance range where the electronic money medium is held over the antenna, and a taximeter that transmits and outputs billing information related to taxi fares using the information processing function; A means for realizing communication between the electronic money and using the information processing function to obtain a balance amount of electronic money charged in the RFID chip via the RFID reader / writer, and Every time billing information is displayed on the indicator and received from the taximeter, the cumulative billing fee is based on the received billing information. And a second process of subtracting and displaying the deposited accumulated charge amount from the amount displayed on the display, and performing the RFID reader / writer The accumulated billing amount deposited is deducted from the electronic money charged in the RFID chip.

  According to the present invention, when a taxi fare is paid with electronic money charged in electronic money media readable by RFID technology, the electronic remaining when the taxi fare is withdrawn from the electronic money media that changes with the operation of the taxi. The amount of money balance can be informed to the passenger, and if the passenger has multiple electronic money media, the electronic money balance amount can be informed to the passenger for any electronic money media, Further, since the operation of holding the electronic money medium over the antenna of the RFID reader / writer is required when paying the taxi fare by the electronic money medium, it is possible to give the passengers a sense of security.

  An embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic diagram showing the overall system configuration. This system includes a taxi passenger terminal 101 and a taximeter 201. That is, the taxi meter 201 is installed in the dashboard 13 in front of the front passenger seat 12 in the passenger compartment 11 of the taxi. The taxi meter 201 is located at a position where it can be operated from the driver's seat 14 and is visible from both the driver's seat 14 and the passenger seat 15 on the rear seat side. In the taxi shown in FIG. 1, the front seat is a bench seat. Therefore, the passenger terminal 101 for taxis is attached to a position between the front driver's seat 14 side and the front passenger seat 12 side which is a bench seat so that the passenger sitting in the passenger seat 15 can visually recognize and operate the taxi passenger terminal 101. It is arranged in the upper part of the front seat.

  FIG. 2 is a perspective view of the passenger terminal 101 for taxi. The taxi passenger terminal 101 includes a housing 102 formed of resin and having a small depth.

  FIG. 4 is a block diagram illustrating a hardware configuration of the taxi passenger terminal 101. The taxi passenger terminal 101 includes a CPU 105 that executes various arithmetic processes and controls each unit. Connected to the CPU 105 via a system bus SB are a ROM 106 for fixedly storing fixed data including a computer program, a RAM 107 for storing variable data in a rewritable manner, and a VRAM 108 for generating a display image to be displayed on the LCD 103. ing. Such CPU 105, ROM 106, RAM 107, VRAM 108 and system bus SB are formed as an integrated circuit.

  In addition to the LCD 103 described above, an RFID reader / writer 104, an audio unit 109, a monitoring camera 110, and a communication interface 111 are also connected to the CPU 105 via the system bus SB and are controlled by the CPU 105.

  The RFID reader / writer 104 can perform non-contact communication with an RFID chip 301 a provided in the electronic money medium 301 via an antenna (not shown). As such an RFID reader / writer 104, for example, an electromagnetic coupling reader / writer having a maximum communicable distance of about several centimeters is used. Therefore, the RFID reader / writer 104 is configured to limit the distance range of the contactless communication to a distance range where the electronic money medium 301 is held over the antenna.

  The voice unit 109 includes a voice synthesis LSI (not shown), and has a configuration in which the voice synthesized by the voice synthesis LSI is converted into an analog signal, amplified, and output from the speaker 112.

  The surveillance camera 110 has a CCD camera configuration, and images the passenger sitting in the passenger seat 15.

  The communication interface 111 realizes data communication between the taxi passenger terminal 101 and the taximeter 201. The data communication in this case may be either wired communication or wireless communication, and the format is not limited in any case.

  Here, the microcomputer having the CPU 105 as a main component configures the information processing unit 151 because the CPU 105 executes various information processing in accordance with the computer program stored in the ROM 106. By such an information processing section 151, the taxi passenger terminal 101 exhibits an information processing function.

  FIG. 5 is a block diagram illustrating a hardware configuration of the taximeter 201. The taximeter 201 has a CPU 206 that executes various arithmetic processes and controls each unit. A CPU 207 is connected to a ROM 207 that fixedly stores fixed data including a computer program, a RAM 208 that stores variable data in a rewritable manner, and a VRAM 209 that generates a display image to be displayed on the LCD 203 via a system bus SB. ing. Such CPU 206, ROM 207, RAM 208, VRAM 209 and system bus SB are formed as an integrated circuit.

  In addition to the LCD 203, the tariff selection button 204, and the function button 205, the clock circuit 210, the distance pulse generator 211, and the communication interface 212 are also connected to the CPU 206 via the system bus SB and are controlled by the CPU 206.

  The clock circuit 210 acquires time information from a timer included in a microcomputer including the CPU 206 as a main component, and calculates a current time or calculates a time from one time to another.

  The distance pulse generator 211 executes a calculation process for replacing a rotation pulse signal obtained from, for example, an axle of a taxi with a travel distance of the taxi.

  The communication interface 212 realizes data communication between the taximeter 201 and the taxi passenger terminal 101. The data communication in this case may be either wired communication or wireless communication, and the format is not limited in any case.

  Here, the microcomputer mainly composed of the CPU 206 constitutes the information processing unit 251 because the CPU 206 executes various kinds of information processing according to the computer program stored in the ROM 207. With such an information processing unit 251, the taximeter 201 exhibits an information processing function.

  FIG. 6 shows the concept of a tariff applied to each tariff in the taximeter 201, a tariff selection button 204 that is pressed to apply the tariff, and the LCD 103 of the taxi passenger terminal 101 when each tariff is applied. It is a schematic diagram which shows the display displayed on each in association with each other.

  The taximeter 201 defines various tariffs in its ROM 207. The basic tariff is a fee system in which an additional fee depending on distance or time is added to the basic fee (initial fee) for the first ride. The first boarding fee is 660 yen up to 2 km as an example. The additional fee is 80 yen for every 274m added as the distance additional fee, and 80 yen for every 1 minute 40 seconds when traveling at 10 km / h or less as the time additional fee. The time addition fee is added regardless of the first boarding fee. The first boarding fee and the distance-added fee are defined as a tariff for the distance-based fare. The distance in this case is calculated by the output of the distance pulse generator 211 shown in FIG. The time-added fee is stipulated as a tariff for the time-distance combined fare. The time in this case is calculated from the output of the clock circuit 210 shown in FIG.

  As other tariffs, the taxi meter 201 defines late night / early morning surcharges, incoming car forwarding charges, wireless waiting charges, reservation charges, disability discounts and long distance discounts in the ROM 207. Late night and early morning surcharge is a tariff applied in the time zone from 23:00 to 5:00, and is increased by 30%. The pick-up fee is a tariff that is applied before the customer arrives at the place called and called, and the initial fare amount is specified as the maximum amount. The wireless waiting fee is a tariff that is applied after 5 minutes have elapsed after arrival at the site when a taxi that has arrived at the site is waited for the convenience of the customer upon receiving an application from the customer via a wireless base station. An amount of 80 yen is specified every 50 seconds. The reservation fee is a tariff generated by a reservation, and 400 yen is defined for each reservation. The disabled person discount is a tariff that defines a discount for the disabled person, and one discount is defined. The long distance discount is a tariff applied to an amount exceeding 9,000 yen, and one discount is specified.

  As a basic operation of the taximeter 201, first, when a passenger is placed, the rent button 204b is pressed. When the passenger arrives at the designated location, the payment button 204c is pressed. That is, the fee is calculated by an event that occurs between the pressing of the hiring button 204b and the pressing of the payment button 204c. When the passenger gets off and waits for the next passenger, the empty vehicle button 204a is pressed. In response to such an operation on the taximeter 201, on the taxi passenger terminal 101 side, the LCD 103 displays “rental”, “payment”, and “empty car”.

  Next, as a case where a tariff other than the basic tariff is selected, first, a midnight / early morning discount is applied. The midnight / early morning discount is automatically applied when the time counted by the clock circuit 210 shown in FIG. 5 is from 21:00 to 5:00 the next morning. In this case, on the taxi passenger terminal 101 side, a display of “midnight charge” is displayed on the LCD 103 (see FIG. 2).

  Another example of a tariff that is automatically applied is a long-distance discount tariff. That is, if the taxi fare calculated by the information processing unit 251 of the taximeter 201 shown in FIG. 5 by each tariff exceeds 9,000 yen, a long-distance discount is applied to the excess amount. In this case, on the taxi passenger terminal 101 side, “Discount Application” is displayed on the LCD 103.

  Instead of these automatically applied tariffs, the tariffs applied by an active action of pressing the tariff selection button 204 will be described.

  First, when the drop-in button 204d is pressed, a tariff to which the pick-up charge is applied is selected. In this case, on the side of the taxi passenger terminal 101, the display “LCD fare” is displayed on the LCD 103.

  Further, when the waiting button 204e is pressed, a tariff to which a wireless waiting fee is applied is selected. In this case, on the taxi passenger terminal 101 side, “waiting fee” is displayed on the LCD 103.

  When the reservation button 204f is pressed, a tariff to which a reservation fee is applied is selected. In this case, the taxi passenger terminal 101 displays “reservation fee” on the LCD 103.

  When the discount button 204h is pressed, a tariff to which the disabled person discount is applied is selected. In this case, on the taxi passenger terminal 101 side, “Discount Application” is displayed on the LCD 103.

  When the high speed button 204g is pressed, a tariff to which a high speed charge is applied is selected. In tariffs to which high-speed fares are applied, tariffs with time / distance fare are not selected, and charges are calculated only by tariffs with distance fare. In this case, the taxi passenger terminal 101 displays “high speed” on the LCD 103.

  FIG. 7 is a flowchart showing processing executed by the taximeter 201. The processing of this flowchart is executed according to the computer program stored in the ROM 207 by the information processing unit 251 provided in the taximeter 201. The information processing unit 251 of the taximeter 201 determines whether or not the tariff selection button 204 has been pressed (step S201), whether or not there is an extra time zone (or more than 9,000 yen) (step S202), and whether or not a charging event has occurred ( Step S203), waiting for determination of whether or not payment status information has been received (step S204).

  FIG. 8 and FIG. 9 are flowcharts showing processing executed by the taxi passenger terminal 101. The flowchart shown in FIG. 8 mainly shows a processing routine of electronic money balance display processing. The flowchart shown in FIG. 9 mainly shows a processing routine for settlement processing. The processing of the flowcharts shown in FIGS. 8 and 9 is executed by the information processing unit 151 provided in the taxi passenger terminal 101 in accordance with the computer program stored in the ROM 106. This process is performed by determining whether or not communication with the RFID chip 301a of the electronic money medium 301 is established (step S101), determining whether or not charging information is received from the taximeter 201 (step S106), and from the taximeter 201. Waiting for reception information presence / absence determination (step S107). If those events do not occur, communication is not established with the RFID chip 301a of the electronic money medium 301 (N in step S101), and no billing information is received from the taximeter 201 (N in step S106). The processing routine is that no information is received from the taximeter 201 (N in step S107).

  Refer to the flowchart shown in FIG. When the information processing unit 251 of the taximeter 201 obtains a determination result that the tariff selection button 204 is pressed in the determination of whether or not the tariff selection button 204 is pressed (step S201), the charge calculation of the tariff selection button 204 is performed. Therefore, the corresponding tariff is set (step S205), and the corresponding tariff information is displayed on its own LCD 203 (step S206). In addition, the information processing unit 251 of the taximeter 201 determines that it is in the premium time zone (or more than 9,000 yen) in the above-described presence / absence determination (or more than 9,000 yen) (step S202). Even in the case (Y in step S202), the corresponding tariff is set for the charge calculation (step S205), and the corresponding tariff information is displayed on its own LCD 203 (step S206). And corresponding tariff information is transmitted to the passenger terminal 101 for taxis (step S207).

  Reference is made to the flowchart shown in FIG. When the information processing unit 251 of the taximeter 201 transmits the tariff information to the taxi passenger terminal 101 in step S207 in the flowchart illustrated in FIG. 7, the information processing unit 151 of the taxi passenger terminal 101 determines that the information is received from the taximeter. (Y in step S107). Then, display update processing of the LCD 103 is executed (step S109). By this display update process, the corresponding display illustrated in FIG. 6 is displayed on the LCD 103 of the taxi passenger terminal 101.

  Here, the processing when each tariff selection button 204 is pressed will be described individually with reference to the flowcharts shown in FIGS.

  If the information processing unit 251 of the taximeter 201 determines that the payment button 204c is pressed in step S201, the information processing unit 251 displays “payment” on the LCD 203 in step S206 without selecting a tariff for charge calculation in step S205. In step S207, the payment tariff information is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “payment” on the LCD 103 (see FIG. 6). As shown in FIG. 9, the information processing unit 151 of the taxi passenger terminal 101 determines payment instruction reception (Y in step S151), and starts the processing of the flowchart shown in FIG. This process will be described in detail later with reference to FIG.

  If the information processing unit 251 of the taximeter 201 determines in step S201 that the incoming call button 204d has been pressed, it selects a tariff for the incoming vehicle forwarding fee in step S205, and displays “incoming” on the LCD 203 in step S206. Then, in step S207, the tariff information of the incoming car is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107, and displays the “arrival fee” on the LCD 103 (see FIG. 6).

  If the information processing unit 251 of the taximeter 201 determines that the waiting button 204e is pressed in step S201, the information processing unit 251 selects a wireless waiting tariff in step S205, and displays “waiting” on the LCD 203 in step S206. In step S207, the tariff information waiting for wireless transmission is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “waiting fee” on the LCD 103 (see FIG. 6).

  If the information processing unit 251 of the taximeter 201 determines that the reservation button 204f is pressed in step S201, the information processing unit 251 selects a reservation fee tariff in step S205, and displays “reservation” on the LCD 203 in step S206. In step S207, the reserved tariff information is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “reservation fee” on the LCD 103 (see FIG. 6).

  If it is determined in step S201 that the high speed button 204g has been pressed, the information processing unit 251 of the taximeter 201 selects the tariff for the distance-based fare in step S205 and stops selecting the tariff for the time-distance combined fare, and then proceeds to step S206. To display “high speed” on the LCD 203. In step S207, high-speed tariff information is transmitted to the taxi passenger terminal 101. In response to this, the information processing unit 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “high speed” on the LCD 103 (see FIG. 6).

  If the information processing unit 251 of the taximeter 201 determines that the discount button 204h is pressed in step S201, the information processing unit 251 selects a tariff for disability discount in step S205, and displays “discount” on the LCD 203 in step S206. In step S 207, the tariff information for the disabled person is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “apply discount” on the LCD 103 (see FIG. 6).

  If the information processing unit 251 of the taximeter 201 determines that it is a premium time zone in step S202, it selects a tariff for the late night and early morning premium in step S205, and displays “extra” on the LCD 203 in step S206. In step S207, the late-night early-morning tariff information is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107, and displays “midnight charge” on the LCD 103 (see FIGS. 2 and 6).

  When the information processing unit 251 of the taximeter 201 determines in step S202 that the taxi fare that has been generated so far is more than 9,000 yen, it selects a long-distance discount tariff in step S205, In step S206, “discount” is displayed on the LCD 203. In step S207, the far-distance discount tariff information is transmitted to the taxi passenger terminal 101. In response to this, the information processing section 151 of the taxi passenger terminal 101 determines information reception from the taximeter 201 in step S107 and displays “apply discount” on the LCD 103 (see FIGS. 2 and 6).

  Refer to the flowchart shown in FIG. The taxi meter 201 is basically charged by adding the initial charge, which is a basic charge, and an additional charge that may occur thereafter. The aforementioned tariffs form the basis for such taxi fare calculations. Therefore, when the information processing unit 251 of the taximeter 201 determines that the rent button 204b is pressed in step S201 (Y in step S203), the tariff for the distance-based fare and the time-distance combined fare is selected in step S205, In step S206, “rental” is displayed on the LCD 203, and in step S207, tariff information of the rental is transmitted to the taxi passenger terminal 101. This is as described above. On the other hand, if the hiking button 204b is pressed, the initial boarding fee will be generated. Therefore, in step S203, it is determined whether a charging event has occurred (Y in step S203). The determination that the charging event has occurred in step S203 (Y in step S203) is not limited to the case where the hire button 204b is pressed, and similarly occurs when an additional fee is subsequently generated. When it is determined that a charging event has occurred (Y in step S203), the information processing unit 251 of the taximeter 201 executes a fee calculation process according to the currently selected tariff (step S208). A fee corresponding to the LCD 203 of the 201 is displayed (step S209). Then, billing information including the billing amount is transmitted to the taxi passenger terminal 101 (step S210).

  When the information processing unit 251 of the taximeter 201 determines that the payment status information 141 (see FIG. 11) has been received from the taxi passenger terminal 101 (Y in step S204), the information processing unit 251 follows the received payment status information 141. Sales processing is executed in the registration memory for each payment method (step S211). This process will be described later.

  Here, the processing executed by the information processing unit 151 of the taxi passenger terminal 101 will be described in detail with reference to the flowchart shown in FIG. 8 (mainly displaying the balance of electronic money) and the flowchart shown in FIG. 9 (mainly payment processing). Explained. Here, a description will be given based on one example. This case is the case illustrated in FIGS. 10 and 11.

  FIG. 10 is a schematic diagram showing an example of the state transition of the display content that occurs on the LCD 103 of the taxi passenger terminal 101, together with an event represented by a pattern that causes the state transition to occur. First, the taxi passenger terminal 101 supports settlement using the electronic money media 301. That is, when the electronic money is charged in the RFID chip 301a of the electronic money medium 301, the taxi fare can be paid by the electronic money. Therefore, when a passenger in a taxi wishes to make a payment with the electronic money medium 301, the electronic money medium 301 is held around the LCD 103 of the passenger terminal 101 for taxi (see FIG. 10A). Thereby, the RFID reader / writer 104 establishes communication with the RFID chip 301 a provided in the electronic money medium 301. Therefore, as shown in the flowchart of FIG. 8, the information processing unit 151 of the taxi passenger terminal 101 determines establishment of communication with the RFID chip 301a included in the electronic money medium 301 (Y in step S101). Then, the information processing unit 151 reads the unique code from the RFID chip 301a that has established communication (step S102). The unique code in this case is, for example, a code that can specify the owner of the electronic money medium 301 when the electronic money is charged to the RFID chip 301a of the electronic money medium 301 and used. The read unique code is stored in the work area of the RAM 107 (step S102).

  The information processing unit 151 of the taxi passenger terminal 101 reads the amount information of the electronic money charged in the electronic money medium 301 after executing the storage process of the unique code read in step S102 (step S103). The balance being displayed is displayed on the LCD 103 (step S104). The illustration in FIG. 10A is an example in which 12,680 yen is charged in the electronic money medium 301.

  Thereafter, the information processing section 151 of the taxi passenger terminal 101 determines whether or not there is a deposit amount (step S105), and if there is no deposit amount, determines whether or not the billing information is received from the taximeter 201 (step S106). As shown in FIG. 10 (b), if the taxi driver presses the rent button 204b of the taximeter 201, the billing information is transmitted from the taximeter 201 (step S210 in FIG. 7). Then, it is determined to receive the billing information (Y in step S106).

  When the information processing unit 151 of the taxi passenger terminal 101 determines the receipt of the billing information (Y in step S106), the billing amount included in the received billing information is stored in the work area of the RAM 107 as the first processing. The deposit process is executed (step S108). Here, the initial fare of 660 yen is deposited.

  Thereafter, the information processing section 151 of the taxi passenger terminal 101 executes a display update process on the LCD 103 as the second process (step S109). That is, because 660 yen has been deposited in the process of step S108, the balance of the electronic money charged in the electronic money medium 301 is 12,680 yen (see FIG. 10 (a)) to 12,020 yen. Update display is performed (see FIG. 10B). At this time, since it is necessary to display the balance, which is the charge amount of the electronic money in the electronic money medium 301, on the LCD 103 for a while (see FIG. 10A), the display update process in step S109 is performed after the balance display process in step S104. For example, it is executed with a waiting time of about 5 seconds to 10 seconds.

  Here, the meaning of step S105 will be described.

  The process of step S105 is the presence / absence determination of the deposit amount. 10 and 11, the passenger holds the electronic money medium 301 around the LCD 103 of the taxi passenger terminal 101 (see FIG. 10A), and then the taxi driver pays the taxi meter 201. The run button 204b is pressed (see FIG. 10B). Therefore, the information processing unit 151 of the taxi passenger terminal 101 determines the establishment of communication with the RFID chip 301a of the electronic money medium 301 (Y in step S101), and performs the processes in steps S102 to S104. After that, in step S105, it is always determined that there is no deposit amount. On the other hand, after the taxi driver presses the rent button 204b of the taximeter 201 (see FIG. 10B), the passenger holds the electronic money media 301 around the LCD 103 of the taxi passenger terminal 101 ( It is also assumed that (see FIG. 10A). In such a case, the information processing unit 251 of the taxi meter 201 transmits the charging information of 660 yen of the initial boarding fee to the taxi passenger terminal 101 (step S210 in FIG. 7), and accordingly the information of the taxi passenger terminal 101 is transmitted. The processing unit 151 determines the receipt of the billing information (Y in step S106) without determining the establishment of communication with the RFID chip 301a included in the electronic money medium 301 (N in step S101), and step S108. The deposit process is executed at (first process). Incidentally, in this case, no charge is displayed on the LCD 103 of the taxi passenger terminal 101. In such a situation, when the passenger subsequently holds the electronic money media 301 around the LCD 103 of the taxi passenger terminal 101 (see FIG. 10A), the information processing unit 151 of the taxi passenger terminal 101 is the first time here. Determines the establishment of communication with the RFID chip 301a of the electronic money medium 301 (Y in step S101). At this time, since the deposit process has already been performed and the charge amount of 660 yen is stored in the work area of the RAM 107, it should be determined that there is a deposit process in step S105 (Y in step S105). Therefore, in this case, the information processing unit 151 of the taxi passenger terminal 101 executes the display update process of the LCD 103, which is the second process (step S109). At this time, as described above, the display update process in step S109 is executed after a balance display process in step S104, for example, with a waiting time of about 5 seconds to 10 seconds.

  Another situation where step S105 is meaningful will be described. After the passenger holds the electronic money medium 301 over the taxi passenger terminal 101 (see FIG. 10A) and the balance display process (step S104) is performed, the passenger passes another electronic money medium 301 to the taxi passenger. There is a possibility of holding it over the terminal 101. At this time, if it is determined that the billing information is received from the taximeter 201 (Y in step S106), a deposit process is performed in step S108, and the billing amount is stored in the work area of the RAM 107. Therefore, in this case, the establishment of communication with the RFID chip 301a of the new electronic money medium 301 is determined (Y in step S101), and after the processing in steps S102 to S104, the deposit amount in step S105 is determined. The presence or absence is determined (Y in step S105), and the display update process of the LCD 103, which is the second process, is executed (step S109). At this time, as described above, the display update process in step S109 is executed after a balance display process in step S104, for example, with a waiting time of about 5 seconds to 10 seconds. Here, whether or not the passenger holds the electronic money media 301 over the taxi passenger terminal 101 (see FIG. 10A) and then another electronic money media 301 is held over the taxi passenger terminal 101 in step S102. This can be easily determined by determining the identity between the unique code read and stored in the RAM 107 and the newly read unique code.

  If the passenger continues to take a taxi in the state shown in FIG. 10B, an additional fee is generated. When the information processing unit 251 of the taximeter 201 determines that a billing event has occurred (Y in step S203 in FIG. 7), the billing information is transmitted to the taxi passenger terminal 101 through steps S208 to S209 (FIG. 7). 7 step S210). In response to this, the information processing section 151 of the taxi passenger terminal 101 determines that the charging information is received (Y in step S106), executes the deposit process (step S108), and executes the display update process (step S109). FIG. 10C shows a display example of the LCD 103 of the taxi passenger terminal 101 when a charge amount of 240 yen is further generated from the state shown in FIG.

  Refer to the flowchart of FIG. 9 and FIGS. 10 (d) to 10 (e).

  FIG. 10D is a display example on the LCD 103 of the taxi passenger terminal 101 when the taxi driver presses the payment button 204c. When the payment button 204c is pressed, the information processing unit 251 of the taximeter 201 makes a determination to that effect (Y in step S201 in FIG. 7), and uses the tariff information that the payment button 204c is pressed as a taxi passenger terminal. 101 (step S207 in FIG. 7). In response to this, the information processing section 151 of the taxi passenger terminal 101 determines that there is a payment instruction in step S151 as shown in FIG. 9 (Y in step S151). At this time, 11,300 yen is displayed on the LCD 103 of the passenger terminal 101 for taxi (FIG. 10D). Therefore, in this example, it can be seen that the taxi fare was 1,380 yen from the display on the LCD 103 of 12,680 yen shown in FIG. 10 (a) and 11,300 yen shown in FIG. 10 (d). When the information processing unit 151 of the taxi passenger terminal 101 determines that there is a payment instruction (Y in step S151 in FIG. 9), the information processing unit 151 performs a notification process regarding the settlement method (step S152). As an example of this notification process, “The charge is 1,380 yen. Please pay with cash or electronic money. When paying with electronic money, hold your electronic money medium over the passenger terminal for taxis. The synthesized voice such as “Please” is generated by the voice unit 109, and the voice is notified from the speaker 112.

  Thereafter, the information processing unit 151 of the taxi passenger terminal 101 determines whether or not empty vehicle information is received (step S153) and determines whether or not communication is established with the RFID chip 301a included in the electronic money medium 301 (step S154). Waiting to

  When the passenger wishes to settle with the electronic money medium 301, the electronic money medium 301 is held around the LCD 103 of the passenger terminal 101 for taxi. Thereby, the RFID reader / writer 104 establishes communication with the RFID chip 301 a provided in the electronic money medium 301. Therefore, as shown in the flowchart of FIG. 8, the information processing unit 151 of the taxi passenger terminal 101 determines the establishment of communication (Y in step S154). The information processing unit 151 that determines the establishment of communication (Y in step S154) reads the unique code from the RFID chip 301a that has established communication (step S155), and determines whether or not the unique code is already stored in the RAM 107 ( In step S156, it is determined whether or not the stored unique code matches the unique code read this time (step S157). If the electronic money media 301 is held over the taxi passenger terminal 101 for the first time, the unique code storage process in step S102 of FIG. 8 has not been performed. Therefore, in this case, it is determined that the unique code is not stored (N in step S156), and the default value F = null of the flag area of the RAM 107 is set to F = 1 (step S158). The F value in the flag area of the RAM 107 is significant in step S163 described later. On the other hand, when the electronic money media 301 is already held over the taxi passenger terminal 101, the unique code storage process is performed in step S102 of FIG. Therefore, in this case, it is determined that the unique code is stored (Y in step S156), and it is determined whether the unique code stored in the RAM 107 matches the unique code read this time in step S155. (Step S157). As a result, if the electronic money media 301 finally held over the taxi passenger terminal 101 is held again, the unique codes should match. Therefore, in this case, the unique code matches are determined (Y in step S157), and the default value F = null in the flag area of the RAM 107 is set to F = 2 (step S159). The F value in the flag area of the RAM 107 is significant in step S163 described later.

  Then, the information processing section 151 of the taxi passenger terminal 101 executes a deposit amount withdrawal process (step S160). In this process, the amount deposited in the RAM 107 by the deposit process in step S108 shown in FIG. 8, that is, the taxi fare equivalent amount, is charged to the electronic money medium 301 determined to have established communication in step S154. It is a process of debiting from money.

  FIG. 10E is a display example on the LCD 103 of the taxi passenger terminal 101 when the taxi driver presses the empty car button 204a. When the empty car button 204a is pressed, the information processing unit 251 of the taxi meter 201 determines to that effect (Y in step S201 in FIG. 7), and uses the tariff information that the empty car button 204a is pressed as a taxi passenger terminal. 101 (step S207 in FIG. 7). In response to this, the information processing section 151 of the taxi passenger terminal 101 determines reception of empty vehicle information in step S153 as shown in FIG. 9 (Y in step S153). When the passenger does not wish to make a payment with the electronic money medium 301, that is, when making a cash payment, the taxi passenger terminal 101 should provide empty vehicle information from the taximeter 201. In other words, the taxi driver should immediately press the empty car button 204a after the transaction, and accordingly, the information processing unit 251 of the taximeter 201 transmits empty car information to the passenger terminal 101 for taxi. Yes (step S207 in FIG. 7). Therefore, the taxi passenger terminal 101 that has received the empty vehicle information determines reception of empty vehicle information (Y in step S153 in FIG. 9). In this case, the value of the flag area of the RAM 107 remains the default value F = null. The F value in the flag area of the RAM 107 is significant in step S163 described later.

  The information processing section 151 of the taxi passenger terminal 101 executes the deposit amount deduction processing from the electronic money in step S160, or determines whether or not the empty vehicle information is received in step S153 (Y in step S153), and then settles. Status information 141 is generated (step S161). Then, the generated settlement status information 141 is transmitted to the taximeter 201 (step S162).

  FIG. 11 is a schematic diagram of the payment status information 141. The settlement status information 141 is data in a transmission message format that starts with the header 141a and ends with the EC 141c (end of code). The content 141b is sandwiched between the header 141a and the EC 141c. The content 141b in the first example includes an ID (a) indicating the deposit amount 131b in the settlement status file 131 shown in FIG. 10, a deposit accumulated amount “0 (yen)” of the subsequent deposit amount 131b, and a settlement status file. The ID (b-1) indicating the settlement amount 131c in 131, the subsequent settlement accumulated amount “1380 (yen)”, the ID (b-2) indicating the unique code 131d in the settlement status file 131, and thereafter It is composed of the following unique code “XXX × −XXXXXX”.

  Reference is made to the flowchart of FIG. If the information processing unit 251 of the taximeter 201 determines that the payment status information 141 has been received from the taxi passenger terminal 101 (Y in step S204), the information is sold in the registration memory by payment method according to the received payment status information. Processing is executed (step S211). That is, the taximeter 201 has a sales memory in the RAM 107. Therefore, for example, when the payment status information 141 illustrated in FIG. 11 is received (Y in step S204), the amount “1380 (yen)” recorded in the content 141b included in the payment status information 141 is calculated. It is recorded in the sales memory in the RAM 107 in association with the unique code “XXXXXX-XXXXXX”. In this association, the amount of money “1380 (yen)” recorded in the content 141b is charged to the electronic money medium 301 in which the holder is specified by the unique code “XXXXXX-XXX”. This is an association for meaning that the electronic money has been settled.

  Reference is made to the flowchart of FIG. The information processing unit 151 of the taxi passenger terminal 101 transmits the settlement status information 141 to the taximeter 201 (step S162), and then executes voice notification processing according to the F value set in the flag area of the RAM 107 ( Step S163). The default F value and the F value set by the flag area setting processing in steps S158 and S159 are meaningful for such voice notification.

  In other words, if F = 1, the electronic money media 301 was held over the taxi passenger terminal 101 for the first time, or the electronic money media 301 was already held over the taxi passenger terminal 101, but the last electronic The electronic money medium 301 different from the money medium 301 is held in response to the voice notification in step S152. Therefore, in this case, as an example, a synthesized voice such as “Thank you for paying 1,380 yen with your electronic money. A voice notification is made from 112.

  On the other hand, if F = 2, the electronic money media 301 is already held over the taxi passenger terminal 101, and the same electronic money media 301 as the last held electronic money media 301 is notified by voice notification in step S152. It will be held depending on. Therefore, in this case, as an example, “The fee of 1,380 yen was settled with your electronic money. The balance of electronic money is 11,300 yen as displayed on the passenger terminal for taxis. “Thank you every time.” Is generated by the audio unit 109, and the audio is notified from the speaker 112.

  If the F value remains at the default value F = null, the empty car button 204a is pressed in the taximeter 201, so that the cash settlement is made and the passenger who has settled the cash has already got out of the taxi. It is estimated to be. Therefore, in this case, no voice notification is performed. In the case of cash settlement, the taxi driver will give a thank-you greeting such as “Thank you every time”.

  Reference is made to the flowchart of FIG. When the information processing unit 151 of the taxi passenger terminal 101 determines that the empty vehicle information is received from the taximeter 201 (Y in step S110), various information generated by the current transaction, for example, the unique code stored in the RAM 107 in step S102 In order to delete the information remaining in the work area of the RAM 107 in order to generate the settlement status information 141 illustrated in FIG. 11 and the F value (F = 1, F = 2) of the flag area of the RAM 107, etc., a RAM clear process Is executed (step S111), and the process is terminated.

  As described above, according to the present embodiment, when paying a taxi fare with electronic money charged in electronic money media 301 readable by RFID technology, electronic money media 301 that changes with taxi operation can be used. Passengers can be informed of the balance of electronic money remaining when taxi fares are withdrawn. Moreover, when the passenger has a plurality of electronic money media 301, the electronic money balance amount can be notified to the passenger for any electronic money media 301. Then, when paying the taxi fare by the electronic money media 301, the operation of holding the electronic money media over the antenna of the RFID reader / writer 104 is required, so that the passenger can be notified of the payment timing of the electronic money from the electronic money media 301. This can give passengers a sense of security.
