Description

  Embodiments described herein relate generally to a fee collection system and a fee collection method.

  Conventionally, ETC systems (Electronic Toll Collection System) and magnetic toll tickets have been used as methods for collecting road usage fees (hereinafter simply referred to as “charges”) from vehicles at toll roads such as expressways. Two types of methods are used together.

  The ETC system consists of a roadside device provided on the toll gate side, an in-vehicle device mounted on the vehicle side with an ETC card (IC (integrated circuit) card), and a toll center provided apart from the toll gate Server. In the ETC system, the roadside device, the in-vehicle device, and the toll center server communicate with each other to collect vehicle traffic history information without burdening the user, and calculate and manage tolls. . Also, there is no need to place a staff at the toll gate.

  On the other hand, in the magnetic toll ticket system, at the entrance toll gate, for example, magnetic passage in which information such as vehicle type, entrance toll gate ID (Identifier), entrance toll gate passage time, ticketing machine number, serial number, and vehicle number is printed and magnetically written. A ticket is issued and given to the user. The user carries the vehicle with the magnetic ticket, and passes the magnetic ticket to the staff at the exit toll gate. The staff at the exit toll booth reads the magnetic ticket into a predetermined device to calculate the fee, and the user pays the fee.

Next, the GPS data storage processing unit 613 acquires GPS data indicating the current location of the mobile terminal 6 and stores it as GPS data 622 in the storage unit 62 (step S6).
Next, the time data storage processing unit 614 acquires current time data based on the internal clock of the mobile terminal 6 and stores it as time data 623 in the storage unit 62 (step S7).

  In this way, at the entrance toll booth, the driver of the vehicle 5 simply holds the mobile terminal 6 that he / she owns over the NFC tag 262, so that the mobile terminal 6 has the entrance toll gate ID 620, the encrypted information 621, the GPS data 622, The time data 623 can be saved.

<Operation at the exit toll gate>
Next, the operation of the exit toll gate control device 3 and the like with data will be described with reference to FIG. 4 (see FIGS. 1 and 2 as appropriate).

  In the exit toll gate control device 3, the reception control unit 311 determines whether data has been received from the portable terminal 6 via the NFC antenna 362. If Yes, the process proceeds to step S12. If No, the process proceeds to step S11. Return to.

  Here, the driver of the vehicle 5 traveling on the toll road and arriving at the exit toll gate holds the portable terminal 6 held by the driver 5 over the NFC antenna 362 of the exit toll booth booth 36 (close to within about 10 cm). Then, the transmission control unit 611 of the portable terminal 6 transmits the entrance toll gate ID 620, the encrypted information 621, the GPS data 622, and the time data 623 of the storage unit 62, and the reception control unit 311 of the exit toll gate control device 3 receives the NFC antenna. The entrance toll gate ID 620, the encrypted information 621, the GPS data 622, and the time data 623 are received via 362 (Yes in step S11).

  In step S12, the decryption unit 312 decrypts the received encrypted information (encrypted information 621) using the common key 321 of the storage unit 32 (step S12).

  Next, in step S13, the abnormality determination unit 313 determines whether or not there is an abnormality. If Yes, the process proceeds to step S14, and if No, the process proceeds to step S15. In step S13, for example, in the following cases (A) to (D), it is determined that there is an abnormality.

(A) When the received entrance toll gate ID 620 and the entrance toll gate ID in the decrypted information do not match (B) The vehicle number in the decrypted information and the vehicle number recognition device 35 of the exit toll gate When the vehicle number recognized by is different

(C) When the received GPS data 622 does not correspond to the entrance toll gate ID in the decrypted information (D) The received time data 623 and the entrance toll gate passage time in the decrypted information are When it does not correspond (is different for more than a predetermined time length)

  In step S <b> 14, the abnormality determination unit 313 notifies (output by image or sound) an abnormality (data alteration, device failure, etc.). Thereby, the operator of the exit toll gate control device 3 can recognize the abnormality.

  In step S15, the fee calculation unit 314 calculates the fee of the vehicle 5 based on the entrance toll gate ID, the entrance toll gate passage time, the vehicle type, and the fee table data 322 in the storage unit 32 in the decrypted information. calculate.

  Next, in step S <b> 16, the control unit 31 displays the calculated fee on the output device 37. After this, if immediate payment of the fare is selected in advance by the driver using the dedicated application 624, the driver of the vehicle 5 is displayed on the output device 37 to the collector of the exit toll booth 36. Pay the fee. If postpayment is selected, the driver of the vehicle 5 does not pay at the exit toll booth, pays later at a convenience store, etc., or adds to the usage fee of the mobile terminal 6 Make a payment.

  In addition, when receiving the toll booth 36 from the driver of the vehicle 5, the toll booth 36 collects the vehicle type in the decrypted information displayed on the display device (not shown) in the exit toll booth 36. As a result, if it is different from the vehicle type of the actual vehicle 5, the fee amount corresponding to the vehicle type of the actual vehicle 5 is transmitted to the driver, and the fee of that amount is received from the driver. In this way, it is possible to deal with a vehicle type discrimination error by the vehicle type discrimination device 24 at the entrance toll gate.

  Thus, according to the toll collection system 1 of the present embodiment, there is a possibility that the occupant of the vehicle 5 possesses the role of the conventional magnetic pass using the inexpensive NFC tag 262 that does not require power. By substituting the portable terminal 6 having a high price, it is possible to reduce the cost for collecting charges from non-users of the ETC system on the toll road.

  Conventionally, when both the ETC system and the magnetic ticket system are used together, in general, the toll road fee is higher for users with a magnetic ticket system (non-ETC system users) than for ETC system users. It was set high. However, in order to make an ETC card, possession of a credit card is a condition, and those who cannot make a credit card or those who do not want to make a credit card have to use a magnetic pass ticket system. According to the toll collection system 1 of the present embodiment, the cost of the toll road toll collection system as a whole can be reduced, and the charges for non-users of the ETC system can be reduced accordingly. Is also big.

  In addition, the information including the entrance toll gate ID, the vehicle entrance toll gate passage time, and the vehicle type is encrypted with a predetermined common key, and then transmitted to the mobile terminal 6 and stored in the ultrasonic wave. By using it at the exit toll gate, high security can be realized. Moreover, since there are almost no portable terminals 6 without a microphone, the portable terminals 6 possessed by the passengers of the vehicle 5 can be utilized simply by installing the dedicated application 624, and the cost can be reduced.

  Further, in step S13 of FIG. 4, it is determined whether or not the entrance toll gate ID based on the entrance toll gate ID 620 stored in the portable terminal 6 matches the entrance toll gate ID in the decrypted information. ((A) above) Even if the former data falsification, it can be easily known.

  Further, in step S13 of FIG. 4, when the portable terminal 6 receives the entrance toll gate ID from the NFC tag 262 of the entrance toll gate, the abnormality determination is performed using the GPS data 622 stored in the storage unit 62 (above (C)), the accuracy of abnormality determination can be increased. However, it is not essential to use the GPS data 622 for abnormality determination.

  Further, in step S13 of FIG. 4, when the portable terminal 6 receives the entrance toll gate ID from the NFC tag 262 of the entrance toll gate, the abnormality determination is performed using the time data 623 saved in the storage unit 62 (above (D)), the accuracy of abnormality determination can be increased. However, it is not essential to use the time data 623 for abnormality determination.

  As mentioned above, although embodiment of this invention was illustrated, the said embodiment is an example to the last, Comprising: It is not intending limiting the range of invention. These embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  For example, the mobile terminal 6 is not limited to a smartphone, and may be a tablet terminal or the like.
