  FIG. 1 is a system diagram showing a configuration example of a valuable value replenishment system including a portable information terminal according to an embodiment of the present invention, and shows a cellular phone 1 as an example of a portable information terminal. This valuable value supplementation system includes a mobile phone 1, a reader / writer device 2, and a wireless LAN base station 3.

  The mobile phone 1 is a mobile information terminal that performs payment processing by receiving billing information via short-range wireless communication. By bringing the mobile phone 1 close to the reader / writer device 2, for example, public transportation such as a railway or a route bus It is possible to perform the settlement processing of the boarding fee. Further, when the mobile phone 1 passes through the reader / writer device 2 at the departure point and the arrival point, it can acquire identification information including the position information of the point from the reader / writer device 2.

  The departure point means a position where the use of public transportation starts. For example, in the case of a railroad, it refers to a departure station that has entered the railway facility premises, and in the case of a route bus, it refers to a stop where the boarding has been taken. Similarly, the arrival point indicates, for example, an arrival station that has entered from the railway facility if it is a railroad, or a stop where it gets off if it is a route bus. In this embodiment, an example in the case of using a railway will be described.

  The reader / writer device 2 is a short-range communication device that performs short-range wireless communication with the mobile phone 1, and is installed, for example, at a ticket gate of each station of a railway facility. The reader / writer device 2 performs processing for transmitting billing information for performing settlement processing to the mobile phone 1. In addition, identification information for specifying the departure point and the arrival point is transmitted to the mobile phone 1.

  The wireless LAN base station 3 is a position information transmitting station that periodically wirelessly transmits position information such as a station name, latitude, and longitude. Here, it is assumed that a process of transmitting the position information of the current position to the mobile phone 1 via the wireless LAN is performed around each station of the railway facility.

  The mobile phone 1 identifies the departure station based on the identification information received from the reader / writer device 2 of the departure station, and identifies the nearest station at that time by acquiring the current position from the wireless LAN base station 3. The boarding fee from the departure station to the nearest station can be calculated. Furthermore, when the remaining amount of valuable value (electronic money) used for boarding fee settlement processing is insufficient, the valuable value can be supplemented via cellular communication.

  FIG. 2 is a block diagram illustrating a configuration example of the mobile phone 1 in FIG. 1, and illustrates an example of a functional configuration in the mobile phone 1. This mobile phone 1 includes an acceleration sensor 11, a movement speed estimation unit 12, a movement speed comparison unit 13, a power supply unit 14, a short-distance communication function unit 15, a position information reception unit 16, a departure point identification unit 17, a boarding fee calculation unit. 18, a charge comparison unit 19, a valuable value supplement inquiry unit 20, a valuable value supplement unit 21, and a cellular communication unit 22.

  The acceleration sensor 11 is a detection element that detects the acceleration of the mobile phone 1 and performs an operation of outputting detection data detected at a predetermined cycle. The movement speed estimation unit 12 performs a process for obtaining the movement speed based on the detection result of the acceleration sensor 11. Specifically, the moving speed is calculated by integrating the acceleration output from the acceleration sensor 11. Here, the speed of the vehicle on which the user is boarded, that is, the speed of the train or the route bus is obtained. The movement speed comparison unit 13 performs processing for comparing the movement speed obtained by the movement speed estimation unit 12 with a threshold value. This threshold is a predetermined speed, and is, for example, 10 km / h here.

  The position information receiving unit 16 performs an operation of receiving position information of the current position by wireless communication. The longest communication distance of this wireless communication is longer than the longest communication distance of short-range wireless communication, for example, several meters to several tens of meters, and communication is performed in a communication range of at least 10 cm or more. The position information receiving unit 16 receives position information of the current position from the wireless LAN base station 3 arranged around each station of the railway facility via the wireless LAN. Here, for example, IEEE 802.1x, OFDM, or the like can be employed as a wireless LAN communication method.

  The power supply unit 14 is a power supply device that supplies power to the position information receiving unit 16 based on the moving speed. Based on the comparison result of the moving speed comparing unit 13, the power supply unit 14 supplies power to the position information receiving unit 16. The presence or absence is switched. By this switching, the position information receiving unit 16 is switched between a state in which the position information acquisition operation is performed by wireless communication and a state in which the position information acquisition operation is not performed. Specifically, when the movement speed obtained by the movement speed estimation unit 12 shifts from a state higher than a threshold to a lower state, power supply to the position information reception unit 16 is started, and the movement speed is higher than the threshold. The power supply to the position information receiving unit 16 is cut off.

  Generally, when the vehicle speed is shifted from a high state to a low state, it is considered that the next stop station is close. On the other hand, when the speed of the vehicle is high, the next stop station is considered to be away. For this reason, the power supply unit 14 selectively supplies power to the location information receiving unit 16 when it is determined that the next stop station is near, thereby allowing the location information receiving unit 16 to consume power by wireless communication. Is reduced.

Further, the power supply unit 14 performs an operation of shutting off the power supply to the position information receiving unit 16 when the state where the moving speed is lower than the threshold value continues for a certain time T ₁ , whereby the position information receiving unit 16 16 power consumption is suppressed. The predetermined time T _1, the user is a period for determining the non-riding period of non-board the vehicle, for example, it is predetermined as longer than transfer time and latency general vehicles.

  The short-range communication function unit 15 transmits and receives signals to and from the reader / writer device 2 by short-range wireless communication. Specifically, a settlement process for reducing the valuable value is performed by receiving billing information from the reader / writer device 2. It also holds valuable value for this settlement process.

  Furthermore, the short-range communication function unit 15 acquires identification information from the reader / writer device 2 at the departure point or the arrival point, and holds this identification information in association with the reception time. The identification information is information for specifying a departure point or an arrival point, and is received from the reader / writer device 2 at a ticket gate of a station, for example. This identification information includes position information for specifying a point where the short-range wireless communication is performed and classification information for distinguishing the departure point and the arrival point from each other.

  The departure point specifying unit 17 performs an operation of specifying the departure point and the arrival point based on the identification information held by the short-range communication function unit 15. At this time, the departure point specifying unit 17 acquires the identification information with the latest reception time among the identification information held in the short-range communication function unit 15. Furthermore, the reception time associated with the acquired identification information is confirmed, and it is confirmed that the difference between the reception time and the current time is within a predetermined range, for example, within 10 seconds. In addition, the classification information included in the acquired identification information is confirmed, and it is determined whether the identification information is the departure point identification information or the arrival point identification information. In addition, the structure which the departure point specific | specification part 17 specifies a departure point may be sufficient as a user inputs a departure point.

  Moreover, the departure point specific | specification part 17 is performing the operation | movement which discriminate | determines a campus utilization period by specifying the identification information of both a departure point and an arrival point. The on-site use period is a period from when the departure point is specified until the arrival point is specified.

  The boarding fee calculation unit 18 holds a toll table indicating the tolls between the stations, and refers to the toll table to calculate a boarding fee corresponding to the user's boarding section. In this case, the boarding fee calculation unit 18 performs an operation of calculating the boarding fee up to the current position based on the comparison result of the moving speed comparison unit 13. That is, if the vehicle on which the user is boarding stops at the next stop station, the user's boarding section may be changed and the boarding fee may be changed. For this reason, the boarding fee calculation part 18 discriminate | determines that the next stop station is approaching by detecting that the moving speed of the vehicle fell.

  Specifically, it is determined that the next stop station is approaching at the time of transition from a state where the moving speed is higher than the threshold value to a lower state, and a boarding fee from the departure point to the current position is calculated. In addition, in order to suppress the calculation of the boarding fee when the user is not in the boarding, the boarding fee calculation by the boarding fee calculation unit 18 is performed during the above-described campus use period.

  The fee comparison unit 19 obtains information indicating the remaining valuable value from the short-range communication function unit 15, and performs an operation of comparing the remaining amount with the calculated boarding fee. More specifically, it is determined whether or not the boarding fee is subtracted from the remaining amount of the valuable value, the value is equal to or less than a predetermined amount specified in advance by the user. Here, it is determined whether or not the boarding fee is higher than the remaining value.

  The valuable value replenishment inquiry unit 20 performs an operation for prompting the user to replenish the valuable value based on the comparison result of the fee comparison unit 19. For example, when it is determined that the boarding fee is subtracted from a predetermined amount after subtracting the boarding fee from the remaining valuable value, a confirmation screen for replenishing the valuable value is displayed.

  The valuable value replenishment unit 21 replenishes the valuable value by cellular communication based on the comparison result of the fee comparison unit 19. That is, when it is determined that the boarding fee is subtracted from a predetermined amount after subtracting the boarding fee from the remaining amount of the valuable value, the valuable value is purchased via the cellular communication by the cellular communication unit 22 and the short distance communication function unit 15 Is replenished with valuable value. At this time, a certain amount of valuable value predetermined by the user is supplemented. In addition, it can also replenish so that the valuable value after replenishment may become a fixed amount.

  In addition, the user can designate in advance an operation in the case where the remaining value is insufficient. That is, it can be specified that the valuable value is automatically replenished when it is determined that the boarding fee is subtracted from a predetermined amount after subtracting the boarding fee from the remaining valuable value. Further, instead of automatically replenishing the valuable value, it is possible to specify that a confirmation screen for prompting the user to replenish the valuable value is displayed. The valuable value replenishment unit 21 performs a process of replenishing the valuable value by cellular communication if a user operation for instructing the replenishment of the valuable value is performed on the confirmation screen.

  FIG. 3 is a block diagram illustrating a configuration example of a main part of the mobile phone 1 of FIG. 2, in which a short-range communication function unit 15 including a non-contact IC chip is illustrated. The short-range communication function unit 15 includes a short-range wireless communication unit 151, an identification information acquisition unit 152, a boarding history storage unit 153, a settlement processing unit 154, and a valuable value storage unit 155.

  The short-range wireless communication unit 151 transmits and receives signals to and from the reader / writer device 2 via the short-range communication antenna, thereby performing communication at a short distance (several centimeters to several tens of centimeters) by a so-called non-contact method. Is going. The short distance is about several centimeters, and the short distance wireless communication unit 151 has a longest communication distance of 10 cm or less. Such near field communication can be realized using FeliCa (registered trademark of Sony Corporation) or the like. The near field communication unit 151 receives the identification information from the reader / writer device 2 at the departure point or the arrival point by the near field communication. The identification information includes position information for specifying a point where the short-range wireless communication is performed and classification information for distinguishing the departure point and the arrival point from each other. That is, the short-range wireless communication unit 151 is a second position information receiving unit that receives position information of a departure point or an arrival point from the reader / writer device 2.

  The short-range wireless communication unit 151 performs an operation of receiving billing information from the reader / writer device 2 at the arrival point through short-range wireless communication. For example, when the user passes the ticket gate of the arrival station, the charging information is received from the reader / writer device 2 installed at the ticket gate.

  The identification information acquisition unit 152 acquires identification information via the short-range wireless communication unit 151 and stores it in the boarding history storage unit 153 in association with the reception time.

  The departure point identifying unit 17 in FIG. 2 identifies the departure point based on the identification information stored in the boarding history storage unit 153. That is, the short-range communication function unit 15 is modularized so as to operate independently for security improvement, and an interface for inputting and outputting data from the outside of the module is also limited. Therefore, the departure point specifying unit 17 can read only the data in the boarding history storage unit 153.

  For this reason, when detecting the radio wave transmitted from the reader / writer device 2, the departure point specifying unit 17 acquires the identification information having the latest reception time among the identification information held in the boarding history storage unit 153. ing. The radio wave transmitted from the reader / writer device 2 is for supplying power to the IC chip side and can be easily detected. Furthermore, the departure point specifying unit 17 confirms the reception time associated with the acquired identification information, and determines that the difference between the reception time and the current time is within a predetermined range, for example, within 10 seconds. It is confirmed whether or not the identification information is received simultaneously with the radio wave.

  The settlement processing unit 154 performs processing for reducing the valuable value held in the valuable value storage unit 155 based on the billing information received by the short-range wireless communication unit 151. That is, the valuable value corresponding to the received billing information is reduced.

  The valuable value storage unit 155 holds the valuable value used during the settlement process, and the fee comparison unit 19 compares the boarding fee calculated by the boarding fee calculation unit 18 with the balance of this valuable value. It is carried out. Further, the valuable value replenishment unit 21 replenishes the valuable value.

  If such a configuration is adopted, the moving speed comparison unit 13 compares the moving speed with a threshold value to determine that a point where the passenger can get off is close, and the boarding fee calculation unit 18 determines based on the comparison result. The boarding fee is calculated, and the fee comparison unit 19 compares the boarding fee with the remaining valuable value. For this reason, it can be determined that the remaining value of valuable value after deducting the boarding fee is insufficient before reaching the short-range communication device at the arrival point. Moreover, compared with the case where a boarding fee is calculated for every fixed time and it compares with a threshold value, the electric power consumed by calculation of a boarding fee can be suppressed. Furthermore, since the short-range wireless communication unit 151 receives the position information of the departure point from the reader / writer device 3, the boarding fee from the departure point to the current position can be accurately calculated.

  In addition, when moving from a state where the moving speed is higher than the threshold value to a lower state, it is determined that a point where the user can get off is near, and the position information receiving unit 16 acquires the current position by wireless communication. The boarding fee up to the current position can be calculated before the payment processing by the payment processing unit 154 is performed. On the other hand, when the moving speed is higher than the threshold value, it is determined that the point where the passenger can get off is away, and the power supply unit 14 cuts off the power supply to the position information receiving unit 16, so that the position information is acquired. The power consumed by the wireless communication can be suppressed.

  FIG. 4 is an explanatory diagram showing an operation example of the mobile phone 1 of FIG. 2, and shows a state where the vehicle 31 on which the user has boarded moves from the departure station 32A to the stop station 32B. First, immediately after the vehicle 31 departs from the departure station 32A, the moving speed V of the vehicle 31 is lower than the threshold of 10 km / h. In this case, the power supply unit 14 cuts off the power supply to the position information receiving unit 16, and the position information receiving unit 16 does not acquire the position information of the current position. The moving speed V is obtained by the acceleration sensor 11 and the moving speed estimating unit 12 of the mobile phone 1.

  Next, the moving speed V becomes higher than 10 km / h. In this state, since the next stop station 32B is still away, the power supply to the position information receiving unit 16 is cut off, and the position information receiving unit 16 does not acquire the position information of the current position. When the vehicle 31 further approaches the stop station 32B, the moving speed V becomes lower than 10 km / h. In this case, the power supply unit 14 supplies power to the position information receiving unit 16, and the position information receiving unit 16 communicates with the wireless LAN base station 3 installed around the stop station 32B via the wireless LAN. The position information indicating the current position is received. Based on this position information, a boarding fee from the departure station 32A to the stop station 32B is calculated by the boarding fee calculator 18.

  When the user does not get off the vehicle 31 at the stop station 32B, the same process is repeated each time the vehicle 31 approaches the next stop station, and the wireless LAN base station 3 arranged around each stop station wirelessly Position information indicating the current position is received by the LAN. By adopting this configuration, the boarding fee is calculated before or immediately after stopping at each stop station. Therefore, before the user reaches the reader / writer device 2 at the ticket gate of the stop station, the remaining valuable value is The shortage can be replenished by cellular communication.

  Steps S101 to S107 in FIG. 5 are flowcharts showing an example of the departure point specifying process in the mobile phone 1 in FIG. First, the short-range wireless communication unit 151 receives identification information from the reader / writer device 2 (step S101). Next, the identification information acquisition unit 152 acquires the identification information from the short-range wireless communication unit 151 and stores it in the boarding history storage unit 153 in association with the reception time (step S102). On the other hand, when detecting the radio wave transmitted from the reader / writer device 2, the departure point specifying unit 17 reads out the identification information having the latest reception time among the identification information held in the boarding history storage unit 153 (Step S103, S104). Next, based on the classification information included in the identification information, it is determined whether or not the read identification information is the departure station identification information (step S105). When the read identification information is the identification information of the arrival station, the process returns to step S101.

  If the read identification information is the identification information of the departure station, a determination is made of the magnitude of the difference between the reception time of the identification information and the current time (step S106). That is, if the user passes through the reader / writer device 2 at the ticket gate of the departure station and a radio wave transmitted from the reader / writer device 2 is detected, the identification information received from the reader / writer device 2 is read out. Therefore, the difference between the reception time and the current time becomes small. On the other hand, for example, when a radio wave transmitted from the reader / writer device 2 is detected at the time of product purchase, since the identification information of the reader / writer device 2 is not stored, the identification information received before that is read out. In this case, the difference between the reception time of the identification information and the current time becomes large. Therefore, it is possible to prevent erroneous identification information from being read by determining the time difference.

  If the difference between the reception time of the identification information and the current time is within a predetermined range, the departure station corresponding to the position information of the identification information is specified, and the process is terminated (step S107). If the difference between the reception time of the identification information and the current time is not within the predetermined range, the process returns to step S101.

  Steps S201 to S205 in FIG. 6 are flowcharts illustrating an example of valuable value replenishment processing performed after the departure point confirmation processing in FIG. First, when the departure point confirmation process of FIG. 5 is completed, the boarding fee calculation unit 18 determines that the premises use period has started, and the moving speed comparison unit 13 compares the moving speed with a threshold value (step S201). If the movement speed is higher than the threshold, it is determined whether or not the movement speed is lower than the threshold (step S202). If the moving speed is lower than the threshold value, boarding fee confirmation processing is performed (step S203). Furthermore, the boarding fee calculation unit 18 determines whether or not the user has passed through the reader / writer device 2 at the arrival point (step S204). When the user passes through the reader / writer device 2 at the arrival point and the settlement processing unit 154 performs settlement processing for the boarding fee, the boarding fee calculation unit 18 determines that the on-site usage period has ended and ends the processing. (Step S204).

Also, if the user does not pass through the reader-writer device 2 arrival point, fare calculation unit 18 determines whether a predetermined time T ₂ has elapsed at a lower moving speed threshold value (step S205) . The predetermined time T ₂ are, a period for determining that the user is finished payment of fare, longer than the predetermined time T ₁ of the order to determine the non-riding time the user does not ride in the vehicle. If the moving speed is a predetermined time T ₂ lower than the threshold condition has passed, already completed payment of fare is determined to premises use period has ended, the process ends. On the other hand, when the moving speed is not lapse of a predetermined time _{T 2} lower than the threshold condition, the process procedure of step S201~S205 are repeated.

  Steps S301 to S307 in FIG. 7 are flowcharts showing an example of the boarding fee confirmation process (step S204) in FIG. First, the position information receiving unit 16 acquires the position information of the current position by wireless LAN (step S301). Next, the boarding fee calculation unit 18 calculates a boarding fee from the departure station to the current position (step S302). Furthermore, the fee comparison unit 19 compares the calculated boarding fee with the remaining valuable value held in the valuable value storage unit 155 (step S303). If the boarding fee is less than or equal to the remaining value, the process proceeds to step S305.

  On the other hand, when the boarding fee is higher than the remaining value, it is determined that the remaining value is insufficient, and the value replenishment unit 21 replenishes a predetermined certain amount of value through cellular communication. (Step S304). Further, it is determined whether or not the movement speed has shifted to a state higher than the threshold (step S305). If the movement speed is higher than the threshold value, it is determined that the user does not get off the vehicle at the stop station and the vehicle on which the user is boarding is moving to the next stop station, and the power supply unit 14 Shuts off the power supply to the position information receiving unit 16 (step S307) and ends the process.

On the other hand, when the moving speed is not shifted to above the threshold condition, it determines whether or not a predetermined time at a lower moving speed threshold state T ₁ is has elapsed (step S306). The predetermined time T ₁ is a period for determining the non-riding time the user does not ride in the vehicle. If the moving speed is a predetermined time T ₁ lower than a threshold condition has elapsed blocked, is determined to be the waiting time or transit time of the vehicle, the power supply 14 is a power supply to the position information receiving unit 16 Then, the process ends (step S307). If the moving speed is a predetermined time T ₁ lower than the threshold condition has not elapsed, the processing procedure of steps S301~S306 are repeated.

In this manner, the fare calculation unit 18, when the state moving speed is lower than the threshold value has continued beyond a predetermined time T _2, it determines that payment of the fare has been completed (step S205 in FIG. 6), The boarding fee is not calculated until the identification information of the departure point is next received by the short-range wireless communication unit 151 (steps S101 and S105 in FIG. 5). For this reason, when the user completes payment of the boarding fee without passing through the short-range communication device at the arrival point, it is possible to suppress unintentional replenishment of high value.

According to this embodiment, when the state moving speed is lower than the threshold value continues over a predetermined time T _1, the power supply unit 14, to determine that the transfer time or latency of the vehicle position The power supply to the information receiving unit 16 is cut off. For this reason, the electric power consumed by the wireless communication for acquiring position information can be further reduced.

  Further, when it is determined that a point where the passenger can get off is near, the boarding fee calculation unit 18 calculates the boarding fee, and based on the comparison result between the boarding fee and the remaining valuable value, the valuable value supplementing unit 21 Replenishment of valuable value. For this reason, when the boarding fee payment process is performed with the short-range communication device at the arrival point, it is possible to suppress the shortage of the remaining valuable value, and the convenience can be improved.

  Further, when it is determined that the point where the passenger can get off is close, the boarding fee calculation unit 18 calculates the boarding fee, and based on the comparison result between the boarding fee and the remaining valuable value, the valuable value supplementation inquiry unit 20 , Prompting the user to replenish the valuable value. Therefore, it is possible to notify the user that the remaining valuable value is small before performing the boarding fee settlement process with the short-range communication device at the arrival point, and the convenience can be improved.

  In the present embodiment, the example in which the position information receiving unit 16 acquires the position information of the current position via the wireless LAN has been described, but the present invention is not limited to this. For example, the position information may be acquired by receiving a signal from a GPS (Global Positioning System) satellite. Moreover, the structure which discriminate | determines the stop station located in the service area of this base station by acquiring the positional information which identifies the base station of the communication destination of the cellular communication part 22 may be sufficient.

Further, in this embodiment, the power supply unit 14, when the state moving speed is lower than the threshold value has continued beyond a predetermined time T _1, for example for cutting off the power supply to the position information receiving unit 16 Although described, the present invention is not limited to a configuration in which the position information receiving unit 16 continuously acquires position information. For example, it may be configured that the position information receiving unit 16 determines that the position information indicating the current position has been successfully acquired, and the power supply unit 14 cuts off the power supply to the position information receiving unit 16.

  Further, in the present embodiment, an example in which the boarding fee calculation unit 18 calculates the boarding fee from the departure point to the current position when the movement speed is higher than the threshold value and the state is lower than the threshold value. However, the present invention is not limited to the configuration having one threshold. For example, when a first threshold value and a second threshold value lower than the first threshold value are determined and the movement speed is higher than the first threshold value, the state moves to a state lower than the second threshold value. The boarding fee calculation unit 18 may calculate the boarding fee from the departure point to the current position.
