Description

  Embodiments described herein relate generally to a toll collection system and apparatus.

In a conventional toll collection system for toll roads (for example, ETC (electronic toll collection (registered trademark) system)), two pieces of IC (integrated circuit) cards are inserted into the DSRC (dedicated short range communication) in-vehicle device mounted on the vehicle. It is operated by the method. Since the usage history of the user (card identification ID (identification), entrance information, exit information, passage date and time, toll, etc.) is written on the IC card, the gate ( The charge between the entrance and the exit can be specified. Further, it is possible to transmit the traffic details data to the central device that manages the information of the fee collection system, and charge the fee to the user of the fee collection system by credit card settlement at the central device.
However, as described above, when operating by the two-piece method, it is necessary to construct an interface with an external system, such as two-piece maintenance (DSRC on-board unit and DSRC roadside equipment), system construction that enables credit card payment, etc. This results in a relatively large and expensive system configuration.
Use one-piece RFID (radio frequency ID) tags (no IC card, read card ID only) that can be maintained at a lower cost than the two-piece configuration above, and use prepaid balance management if operated by the prepaid method As a result of self-management, a small system can be constructed without establishing an interface with an external system.

However, in the case of such a one-piece system, it is necessary to withdraw the usage fee from the prepaid balance when passing through the exit. It is necessary to synchronize the information on the side, and the usage details are distributed to all toll gates through the central device. Therefore, there is a fear that the load on the network increases in proportion to the number of toll booths and the number of usages.
One of the problems that the embodiments can solve is to provide a toll collection system and apparatus that can reduce the network load with a simple system.

  Hereinafter, exemplary embodiments of the present invention are disclosed. The configuration and control of the embodiment shown below, and the operation and result (effect) brought about by the configuration and control are merely examples. The present invention can be realized by means other than the configuration and control disclosed in the following embodiments, and various effects (including derivative effects) obtained by the basic configuration and control can be obtained. is there.

  In this embodiment, the toll collection system 1 calculates the toll for the vehicle 3 that has passed through one or more gates 2 (such as the entrance gate 2a and the exit gate 2b) provided on the toll road, and Whether to pass through the gate 2 of the vehicle 3 (allowed or rejected) can be controlled in accordance with the status of whether or not collection is possible. The toll collection system 1 includes a plurality of gate devices 7 (first devices) provided in each of the plurality of gates 2 and a central device 8 (second device). The plurality of gate devices 7 and the central device 8 are communicably connected, and can transmit and receive information (data indicating) to each other.

  Here, as illustrated in FIG. 1, the central device 8 and the gate device 7 are separated, and the toll of the vehicle 3 from the entrance gate 2a to the exit gate 2b is calculated to execute a predetermined process. The basic configuration and operation of the fee collection system 1 will be described.

  A wireless tag 4 (RFID tag, communication device, transmission / reception device, response device, transponder) is attached to the vehicle 3. The wireless tag 4 can be incorporated into a card that is handled as a prepaid card, for example. The wireless tag 4 includes a non-rewritable nonvolatile storage unit (not shown) that stores the ID (first identification information, hereinafter referred to as tag ID) of the wireless tag 4. In the present embodiment, the vehicle 3 is not mounted with the vehicle-mounted device.

  The gate 2 is provided with a transmission / reception device 5 and a gate device 7. The transmission / reception device 5 can execute wireless communication with the wireless tag 4 without using the vehicle-mounted device. The transmission / reception device 5 acquires the tag ID from the wireless tag 4.

  The gate device 7 acquires the tag ID from the transmission / reception device 5. The gate device 7 transmits the acquired tag ID to the central device 8 in association with the gate ID (second identification information, the ID of the gate 2 or the ID of the gate device 7). In FIG. 1, the tag ID is described as “TID”, and the gate ID is described as “GID”.

  The central device 8 includes a toll charge storage unit 85 (fourth storage unit, see FIG. 2). The toll storage unit 85 stores tolls corresponding to the gate ID of the entrance gate 2a and the gate ID of the exit gate 2b.

  The central device 8 includes a tag information storage unit 83 (first storage unit, see FIG. 2). The tag information storage unit 83 stores an amount corresponding to a tag ID (card ID, account ID) or a balance of points (data indicating a balance such as a prepaid balance).

  After the vehicle 3 has passed through the exit gate 2b, the central device 8 refers to the toll storage unit 85 and refers to the gate ID of the entrance gate 2a and the gate ID of the exit gate 2b, which are associated with the tag ID of the vehicle 3. Based on the above, the toll (amount of money, the number of points) of the vehicle 3 is calculated. The central device 8 updates the balance by subtracting the toll from the balance corresponding to the tag ID. The central device 8 compares the updated balance with a threshold value (first threshold value). Then, when the updated balance is equal to or less than the threshold value, the central device 8 moves to the gate device 7 of the gate 2 through which the vehicle 3 passes next together with the tag ID at the predetermined gate 2. Processing information for executing processing (for example, outputting an alarm or closing the gate 2 by the circuit breaker 6) is transmitted. FIG. 1 exemplifies a case where both the entrance gate 2a and the exit gate 2b at the time of this traffic can be the entrance gate 2 when the vehicle 3 next uses the toll road. That is, FIG. 1 shows an example in which the tag ID (TID) and the processing information are transmitted to the gate devices 7 of both the entrance gate 2a and the exit gate 2b during the current passage.

  The gate device 7 includes a processing information storage unit 74 (second storage unit, see FIG. 3). The processing information storage unit 74 stores the tag ID and processing information received from the central device 8. When the tag ID of the vehicle 3 that has arrived at the gate 2 matches the tag ID stored in the processing information storage unit 74, the gate device 7 executes the processing indicated in the processing information. The process includes, for example, a process of moving the arm 6a of the circuit breaker 6 to a closed position, a process of outputting a warning display from the display output unit as the output unit 79, and outputting a warning sound from the audio output unit as the output unit 79 There is processing to do.

  Thus, in the fee collection system 1 according to the present embodiment, the vehicle-mounted device is not used. Therefore, according to the present embodiment, the device mounted on the vehicle 3 can be configured more simply because the vehicle-mounted device is unnecessary. In addition, the toll collection system 1 can be more easily operated because the on-board unit registration process is unnecessary.

  Further, as illustrated, in the toll collection system 1 according to the present embodiment, the wireless tag 4 includes, for example, a toll calculation or gate for a toll road such as a traffic history of the vehicle 3 and a balance according to the tag ID. The information that makes it possible to immediately determine whether or not to pass 2 is not stored. For this reason, for example, communication between the gate device 7 and the central device 8 is necessary for calculating the toll of the vehicle 3 and determining whether to permit the passage of the gate 2 of the vehicle 3. Therefore, if the toll collection system 1 calculates the toll and determines whether to permit or not when the vehicle 3 passes through the gate 2, it takes time for the calculation and whether to permit or not, and it is difficult for the vehicle 3 to pass through the gate 2 smoothly. There is a risk of becoming. Therefore, the toll collection system 1 of the present embodiment first allows the passage of the gate 3 of the vehicle 3 regardless of the balance and the like, and executes the predetermined processing when the gate 2 passes the next time.

  In addition, the network load may increase due to communication between the gate device 7 and the central device 8. With respect to this point, in the toll collection system 1 according to the present embodiment, the above-described predetermined processing may be executed when the vehicle 3 passes through the next gate 2, and therefore the ID between the gate device 7 and the central device 8. Or sending information (data) immediately. Therefore, an increase in the network load accompanying communication between the gate device 7 and the central device 8 is easily suppressed. Here, the case where the fee is calculated after the passage through the entrance gate 2a and the exit gate 2b, the balance is determined, and the process is executed at the next entrance gate 2a is exemplified. In the toll collection system 1, the balance can be determined after passing through the entrance gate 2a, and the processing can be executed at the exit gate 2b. The fee collection system 1 according to the present embodiment can also be applied to a system in which a gate 2 is provided between an entrance and an exit, or a system in which only one gate 2 is provided. Hereinafter, a more detailed configuration and control of the fee collection system 1 according to the embodiment will be described.

  The transmission destination storage unit 84 stores a gate ID that is a transmission destination (a transmission destination, a transmission partner) of information to be transmitted from the central device 8 to the gate device 7. The transmission destination storage unit 84 stores, for example, the gate ID of the entrance gate 2 as a transmission destination corresponding to the gate ID of the gate 2 of the exit, and the transmission destination corresponding to the gate ID of the gate 2 of the entrance. The gate ID of the exit gate 2 is stored. The gate ID of the entrance gate 2 corresponding to the gate ID of the exit gate 2 indicates the gate ID of the next entrance gate 2 after the vehicle 3 passes through the exit gate 2. In this case, as an example, the gate ID of the entrance gate 2 existing within a predetermined distance (for example, 100 km) from the exit gate 2 is stored. Further, the gate ID of the exit gate 2 as a transmission destination corresponding to the gate ID of the entrance gate 2 is within a range in which a toll can be calculated after the vehicle 3 passes through the entrance gate 2 (that is, a toll road) Indicates the gate ID of the reachable exit gate 2 (without exiting).

The processing procedure of FIG. 4 can be applied to the gate device 7 corresponding to any of the gate 2a at the entrance, the gate 2b at the exit, and the gate 2 passing therethrough. First, the tag ID acquisition unit 71d (identification information acquisition unit) of the control unit 7 acquires the tag ID from the signal (data) received by the tag communication unit 72 from the wireless tag 4 via the transmission / reception device 5 (S10). . Next, the second determination unit 71e of the control unit 71 determines whether or not the tag ID acquired by the tag ID acquisition unit 71d is stored in the processing information storage unit 74 (S11). If the tag ID acquired by the tag ID acquisition unit 71d is not stored in the processing information storage unit 74 (No in S11), the transmission control unit 71b (third transmission control unit) of the control unit 71 is in S10. The tag communication unit 72 is controlled so that the tag ID and the gate ID acquired by the tag ID acquisition unit 71d are transmitted to the central device 8 in association with each other (S12).

  On the other hand, when the tag ID acquired by the tag ID acquisition unit 71d is stored in the processing information storage unit 74, the processing execution unit 71f (processing execution control unit) of the control unit 71 associates the processing information with the tag ID. Processing information (data indicating the processing content) stored in the storage unit 74 is acquired, and the controllers 76 and 77, and thus the actuator 78 and the output unit 79 are controlled so that the processing is executed (S13).

Examples of the warning display include “Cannot pass because the balance is insufficient”, and “There is an unpaid amount of ○○○○ yen. Please make a payment”. Further, the passage of the vehicle 3 through the gate 2 is rejected (blocked or suppressed). Next, the transmission control unit 71b of the control unit 71 is directed to the central device 8 at a predetermined timing, for example, in response to a transmission request from the central device 8, and the tag ID of the vehicle 3 that has been processed, Information indicating the execution status of the process (information indicating whether the process is completed) is transmitted in association with it (S14). Based on the information transmitted in S <b> 14, the central device 8 can update the information stored in the processing target tag information storage unit 88.

  Although not shown in FIG. 4, the reception control unit 71 a of the control unit 71 receives (acquires, extracts) data directed to the gate device 7 from the signal (data) received by the communication unit 73 from the central device 8. can do. The data directed to the gate device 7 includes, for example, the ID of the gate 2 indicating the transmission destination (or the ID of the gate device 7), the tag ID of the wireless tag 4, and information indicating the processing content corresponding to the tag ID (processing information) Etc. Further, the storage control unit 71 c of the control unit 71 can store the acquired tag ID and the processing information corresponding to the tag ID in the processing information storage unit 74.

  Next, an example of a procedure of processing executed by the control unit 81 of the central apparatus 8 will be described with reference to FIG. In the following, a case where a gate 2 (gate device 7) is provided at each of an entrance and an exit of a toll road (or a position corresponding to the entrance or the exit) is illustrated. First, the reception control unit 81a of the control unit 81 receives the tag ID and the gate ID corresponding to the tag ID from the signal (data) received by the communication unit 82 from the gate device 7 (S20). Next, the first determination unit 81d of the control unit 81 refers to the tag ID storage unit 87 during travel, and the tag ID acquired by the reception control unit 81a is stored in the tag ID storage unit 87 during travel. Whether or not the vehicle 3 to which the wireless tag 4 with the tag ID is attached is traveling on a toll road (S21).

<Process after the vehicle passes through the entrance gate>
When the tag ID acquired by the reception control unit 81a is not stored in the passing tag ID storage unit 87 (No in S21), the vehicle 3 to which the wireless tag 4 with the tag ID is attached is passing the toll road. Instead, it has passed through gate 2 at the entrance of the toll road. In this case, the control unit 81 writes (stores or adds) the tag ID to the tag ID storage unit 87 during travel (S22). Next, when the gate 2 corresponding to the gate ID acquired by the reception control unit 81a is the entrance, the expected balance calculation unit 81h of the control unit 81 is configured for each of the other gates 2 that can be the exit gate 2. An expected balance is calculated (S23). At this time, the expected balance calculation unit 81h acquires the balance of the tag ID from the tag information storage unit 83, acquires the toll for each of the other gates 2 that can be the exit with reference to the toll storage unit 85, By subtracting the toll from the balance, an expected balance (for each exit gate 2) corresponding to each of the other gates 2 that can be exits is calculated. Next, the gate ID selection unit 81i (second identification information specifying unit) of the control unit 81 compares the expected balance of each of the other gates 2 that can be the exit with a threshold (second threshold) (S24). . When there is a gate 2 that is equal to or less than the threshold among the expected balances calculated by the budget balance calculation unit 81h, that is, when the gate ID of the gate 2 that has the same or less than the expected balance is specified ( In step S24, Yes), the processing information acquisition unit 81j of the control unit 81 acquires information indicating the processing content in the gate 2 (or gate device 7) having an expected balance equal to or less than the threshold (second threshold). (S25). At this time, the processing information acquisition unit 81j creates information to be displayed and output at the time of execution of processing on the traveling vehicle (S13 in FIG. 4) including information such as the expected balance calculated by the budget balance calculation unit 81h, for example. can do. Further, the processing information acquisition unit 81j can acquire processing information stored in advance in a ROM, an HDD, or the like, for example. Next, the storage control unit 81c of the control unit 81 stores the transmission destination gate ID, the tag ID, and the processing information in the transmission information storage unit 86 in association with each other (S26). Next, the transmission control unit 81b (second transmission control unit) of the control unit 81 causes the communication unit 82 to have a predicted balance equal to or less than the threshold value (second threshold value) at a predetermined timing. The communication unit 82 is controlled so as to transmit the tag ID and information indicating the processing contents at the exit gate 2 corresponding to the tag ID toward the (or gate device 7) (S27). If there is no gate 2 that is equal to or less than the threshold among the expected balances calculated by the budget balance calculation unit 81h, the series of processes in FIG. 5 ends.

<Process after the vehicle passes through the exit gate>
On the other hand, when the tag ID acquired by the reception control unit 81a is stored in the passing tag ID storage unit 87 (Yes in S21), the vehicle 3 to which the wireless tag 4 with the tag ID is attached travels on the toll road. Passed and passed the gate 2 at the exit of the toll road. In this case, the toll acquisition unit 81f of the control unit 81 acquires the toll for the vehicle 3 with the tag ID (calculates S28). At this time, the toll acquisition unit 81f refers to the toll storage unit 85, and corresponds to the tag ID stored in the passing tag ID storage unit 87 (that is, the gate ID of the gate 2 at the entrance). And a toll corresponding to the gate ID corresponding to the tag ID included in the signal (data) received by the reception control unit 81a (that is, the gate ID of the gate 2 at the exit). Next, the balance update unit 81g of the control unit 81 updates the balance of the tag ID (S29). At this time, the balance update unit 81g acquires the balance of the tag ID from the tag information storage unit 83, and the balance obtained by subtracting the toll acquired by the toll acquisition unit 81f from the balance (old balance, balance before update). (New balance, updated balance) is calculated, and the balance is associated with the tag ID and written in the tag information storage unit 83 to be updated (overwritten).

  Next, the tag ID specifying unit 81e (first identification information specifying unit) of the control unit 81 compares the balance updated by the balance update unit 81g with a threshold (first threshold) (S30). At this time, if the updated balance is the same as or less than the threshold (first threshold), that is, the tag ID that has the updated balance equal to or less than the threshold (first threshold) is specified. In the case (Yes in S30), the processing information acquisition unit 81j of the control unit 81 acquires processing information (S25). At this time, the processing information acquisition unit 81j creates information to be displayed and output at the time of processing execution on the traveling vehicle (S13 in FIG. 4), including information such as the balance updated by the balance update unit 81g, for example. be able to. Further, the processing information acquisition unit 81j can acquire processing information stored in advance in a ROM, an HDD, or the like, for example.

The toll storage unit 85 stores a toll corresponding to the gate ID. The toll fee acquisition unit 81f refers to the toll fee storage unit 85 and acquires a toll fee based on one or more gate IDs corresponding to the tag ID acquired by the tag ID acquisition unit 71d. The balance update unit 81g updates the balance stored in the tag information storage unit 83 by subtracting the toll acquired by the toll acquisition unit 81f from the balance stored in the tag information storage unit 83. The tag ID specifying unit 81e specifies the tag ID based on the balance updated by the balance update unit 81g and stored in the tag information storage unit 83. Therefore, according to the present embodiment, as an example, whether or not to allow the passage of the gate 2 of the vehicle 3 can be controlled according to a new situation of whether or not toll collection is possible.

  In the present embodiment, as an example, the toll collection system 1 includes a toll storage unit 85, an expected balance calculation unit 81h, a gate ID selection unit 81i (second identification information specifying unit), and a transmission control unit 81b. (Second transmission control unit). The toll storage unit 85 stores a toll corresponding to the gate ID. The expected balance calculation unit 81h refers to the toll storage unit 85 and calculates an expected balance for each gate 2 at the exit corresponding to the gate 2 at the entrance from which the tag ID has been acquired. The gate ID selection unit 81i compares the predicted balance calculated by the predicted balance calculation unit 81h with the second threshold value, and the gate ID of the gate 2 at the exit where the predicted balance is equal to or less than the corresponding second threshold value Is identified. The transmission control unit 81b controls to transmit the tag ID specified by the tag ID specifying unit 81e to the gate 2 of the gate ID specified by the gate ID selection unit 81i. Therefore, according to the present embodiment, as an example, the gate 2 of the vehicle 3 depends on whether or not toll collection is calculated in advance for each gate 2 that can be an exit corresponding to the gate 2 at the entrance. It is possible to control whether to pass or not. Therefore, as an example, it is easy to prevent the specified tag ID from being transmitted in vain. In addition, compared with a method of distributing all traffic details to all toll gates, it is limited to a small amount of data when a shortage of balance occurs, so the load on the network can be reduced.
