<First Embodiment>
Hereinafter, the toll collection system according to the first embodiment will be described in detail with reference to FIGS. 1A to 5.

(Overall configuration of toll collection system)
1A and 1B are diagrams showing the overall configuration of the toll collection system according to the first embodiment.
The toll collection system 1 shown in FIG. 1 is installed, for example, at a tollhouse (entrance tollhouse or exit tollhouse) on a toll road. As shown in FIG. 1, the toll collection system 1 is installed in the lane L of the tollhouse and the island I laid on the road side of the lane L.
In the following description, the direction in which the lane L extends (± X direction in FIGS. 1A and 1B) is also referred to as the “lane direction”, and the direction horizontally orthogonal to the lane direction (± Y direction in FIG. 1). ) Is also described as "lane width direction". Further, the side where the vehicle A arrives (-X direction side) in the lane direction of the lane L is also described as the "upstream side" of the lane L, and the side where the vehicle A exits (+ X direction side) is the "downstream side" of the lane L. Also described. Further, based on the direction in which the vehicle A travels (+ X direction), the right side (-Y direction side) is also described as "the right side in the lane width direction", and the left side (+ Y direction side) is also referred to as "the left side in the lane width direction". Describe.

The lane width of the lane L is adjusted by the island I so that vehicles cannot be replaced (overtake, etc.) in the lane L.

As shown in FIGS. 1A and 1B, the toll collection system 1 includes a lane control device 10, vehicle detectors 11A and 11B, a toll collection device 12, a start controller 13, a vehicle detector 14, and a reader device. It has 15 and.

The lane control device 10 (billing device) controls the entire set of various installed devices to perform billing processing for the passenger of the vehicle A who has entered the lane L. The specific processing performed by the lane control device 10 will be described later.

The vehicle detectors 11A and 11B are provided on the most upstream side of the lane L (positions X1A and X1B in the lane direction in FIG. 1A) and detect the entry of the vehicle A into the lane L. The vehicle detectors 11A and 11B are mainly installed for the purpose of managing the queue of vehicles existing on the lane L.
The vehicle detectors 11A and 11B are transmissive vehicle detectors having a floodlight tower arranged on the island I on the left side and a light receiving tower arranged on the island I on the right side. The vehicle detectors 11A and 11B detect the presence of the vehicle A depending on whether or not the light receiving element of the light receiving tower receives the light projected from the light emitting element of the light emitting tower.
The vehicle detector 11B is provided slightly (for example, about 40 cm) downstream of the vehicle detector 11A. As a result, the lane control device 10 can determine whether the vehicle is moving forward or backward based on the order in which the vehicle detection signals output from each of the vehicle detector 11A and the vehicle detector 11B are acquired.

The toll receiving device 12 is provided on the downstream side of the vehicle detectors 11A and 11B (position X2 in the lane direction in FIG. 1A), and receives payment of the toll from the user who boarded the incoming vehicle A. Specifically, the toll collection machine 12 receives the touch of the prepaid IC card possessed by the user and performs the withdrawal process of the amount. Further, the charge collecting machine 12 receives the input of cash from the user and collects the charge.

The start controller 13 is provided further downstream of the toll collector 12 and controls the start of the vehicle A that has entered the lane L. Specifically, the start controller 13 normally closes the open / close bar B and restricts the start of the vehicle A (exit from the lane L). Further, the start controller 13 opens the open / close bar B and permits the vehicle A to start when the payment of the fee is properly received from the user boarding the vehicle A.

The vehicle detector 14 is provided on the most downstream side of the lane L (position X4 in the lane direction in FIG. 1A), and detects the exit of the vehicle A from the lane L. Like the vehicle detectors 11A and 11B, the vehicle detector 14 is installed for the purpose of managing the queue of vehicles existing on the lane L. Further, while the vehicle detection signal is output by the vehicle detector 14, the opening / closing bar B of the start controller 13 is controlled so as not to be closed. This prevents the open / close bar B of the start controller 13 from coming into contact with the moving vehicle.

The reader device 15 reads the tag ID recorded in the tag TG from the RFID tag (hereinafter, also simply referred to as “tag”) TG attached to the vehicle A via wireless communication. The tag ID is information recorded in the tag TG, and is identification information that can individually identify a user of the toll road associated with the tag TG.
As shown in FIGS. 1A and 1B, the reader device 15 is installed above the lane L and radiates radio waves downward (road surface of the lane L) from the installation position. As a result, the reader device 15 forms a wireless communication enable area Q in a predetermined range on the lane L. The reader device 15 can read the tag ID by performing wireless communication with the tag TG existing in the range of the wireless communicable area Q. However, the radio wave radiated by the reader device 15 is reflected on the vehicle body or the surface of the installed device, and is attached to a tag existing outside the range of the wireless communication range Q (for example, a vehicle traveling in the lane next to the lane L). In some cases, the tag ID of the tag) is read.
As shown in FIGS. 1A and 1B, in the reader device 15, the wireless communicable region Q formed on the lane L by the radiated radio wave is the vehicle detection position (position X1A in the lane direction) by the vehicle detectors 11A and 11B. It is installed so as to include X1B).
The size is adjusted so that a plurality of vehicles cannot enter the wireless communication area Q at the same time. For example, the length of the wireless communicable region Q in the lane direction is preferably adjusted to about 1.5 to 2.5 meters. This makes it possible to prevent the tag TG attached to the vehicle traveling behind a certain vehicle from being read first.

(Functional configuration of toll collection system)
FIG. 2 is a diagram showing a functional configuration of the toll collection system according to the first embodiment.
As shown in FIG. 2, the lane control device 10 has a CPU 100, a communication interface 101, and a memory 102.

The CPU 100 exerts various functions by operating according to a program prepared in advance. The functions of the CPU 100 will be described later.

The communication interface 101 is a connection interface for communication with other devices constituting the toll collection system 1.

The memory 102 is a so-called main storage device, and provides a storage area for holding information necessary for the CPU 100 to operate. The acquisition identification information tab TB, which will be described later, is recorded in the memory 102.

The functions of the CPU 100 will be described in detail.
The CPU 100 has functions as a transmission unit 1000, an identification information acquisition unit 1001, a vehicle detection signal acquisition unit 1002, an identification information identification unit 1003, a charge processing unit 1004, and an open / close control unit 1005.

The transmission unit 1000 repeatedly transmits a response request signal to the wireless communicable region Q on the lane L via the reader device 15.
The identification information acquisition unit 1001 acquires the tag ID (tag ID recorded in the tag TG attached to the vehicle A) received by the reader device 15 as a response to the response request signal.
The identification information specifying unit 1003 acquires a vehicle detection signal from the vehicle detectors 11A and 11B arranged so as to be able to detect a vehicle existing within the range of the communicable area Q.
The identification information specifying unit 1003 identifies the tag ID acquired within a predetermined period based on the timing at which the vehicle detection signals from the vehicle detectors 11A and 11B are acquired among the tag IDs acquired a plurality of times.
The billing processing unit 1004 performs billing processing based on the tag ID specified by the identification information specifying unit 1003.
The open / close control unit 1005 opens and controls the start controller 13 when the charge processing by the charge processing unit 1004 is completed. Further, the open / close control unit 1005 closes and controls the start controller 13 when the output of the vehicle detection signal by the vehicle detector 14 is stopped (that is, when the tail of the vehicle A passes the position X4).

(Processing flow of lane control device)
FIG. 3 is a diagram showing a processing flow of the lane control device according to the first embodiment.
4 and 5 are diagrams for explaining in detail the contents of the processing of the lane control device according to the first embodiment.

The flow of processing executed by the lane control device 10 according to the first embodiment will be described in detail with reference to FIGS. 3 to 5.

First, the transmission unit 1000 of the lane control device 10 transmits a response request signal toward the wireless communication enable area Q via the reader device 15 (step S00).

The identification information acquisition unit 1001 of the lane control device 10 determines whether or not the response signal from the tag TG to the response request signal in step S00 has been received via the reader device 15 (step S01).
When the response signal from the tag TG is received (step S01; YES), the identification information acquisition unit 1001 acquires the tag ID included in the response signal and the acquisition time (time stamp) via the reader device 15. Record in the identification information table TB (step S02). When the response signal from the tag TG is not received (step S01; NO), the lane control device 10 proceeds to the next step without performing the process of step S02.

Next, has the vehicle detection signal acquisition unit 1002 of the lane control device 10 acquired vehicle detection signals from each of the vehicle detectors 11A and 11B in a predetermined order (in the order of vehicle detector 11A and vehicle detector 11B)? It is determined whether or not (step S03).
When the vehicle detection signals are not received from each of the vehicle detectors 11A and 11B in a predetermined order (step S03; NO), the lane control device 10 returns to step S00 and repeatedly executes the above process.

When the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order (step S03; YES), the identification information identification unit 1003 of the lane control device 10 is recorded in the acquisition identification information table TB at this point. Performs a process of specifying one of a plurality of tag IDs as a billing target. Specifically, the identification information specifying unit 1003 acquires the tag ID from the timing at which the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order to before the predetermined predetermined period Δt. Is determined (step S04).
When the tag ID acquired from the timing at which the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order to before the predetermined period Δt exists (step S04; YES), the identification information specifying unit 1003 , The tag ID acquired the latest in the predetermined period Δt is specified as a billing target (step S05).

The charge processing unit 1004 of the lane control device 10 performs charge processing based on the tag ID specified in step S05 (step S06). Specifically, the billing processing unit 1004 associates the tag ID specified in step S05 with the billing amount and transmits the billing amount to the higher-level device. In this higher-level device, a tag ID and personal information about a user (for example, an account number, etc.) are associated and recorded. When the host device receives the tag ID and the billing amount from the lane control device 10, the host device uses the personal information associated with the tag ID to perform the billing amount withdrawal process.

When the tag ID acquired from the timing at which the vehicle detection signals are acquired from each of the vehicle detectors 11A and 11B in a predetermined order to before the predetermined period Δt does not exist (step S04; NO), the vehicle detectors 11A and 11B It is assumed that the tag TG of the vehicle A that has passed through the vehicle A could not be read correctly, or that the vehicle A does not have the tag TG in the first place. Therefore, in this case, the charge processing unit 1004 performs charge processing through the charge collector 12 installed in the lane L.
Specifically, the charge processing unit 1004 activates the charge collection machine 12. Specifically, the charge processing unit 1004 first transmits information (charge amount, etc.) necessary for payment by the charge collector 12 to the charge collector 12. The charge processing unit 1004 notifies the passengers and the like of the vehicle A that the payment by the toll receiving machine 12 is required. For example, the charge processing unit 1004 performs an announcement by voice, a guidance display indicating the charge amount, and the like through the speaker and the display of the charge collector 12.
The activated toll collection machine 12 is in a state of waiting for a touch operation of an IC card from a user or a state of waiting for cash to be inserted from a user. The toll collection machine 12 according to another embodiment stands by in a state where it can receive a fixed amount of money at any time, and triggers an operation from the user instead of a signal from the lane control device 10 (charge processing unit 1004). You may collect the fee as.
Subsequently, the billing processing unit 1004 performs billing processing (processing for withdrawing the billing amount for the IC card, processing for the inserted cash) through the charge receiving machine 12 (step S08).

When the billing process is completed by the billing process by the tag ID (step S06) or the billing process by the toll receiving machine 12 (step S08), the open / close control unit 1005 opens and controls the start controller 13 (step S09). As a result, the vehicle A can leave the lane L.

Next, a specific control example of the lane control device 10 based on the processing flow of FIG. 3 will be described with reference to FIGS. 4 and 5.
By repeatedly executing the process of step S00 of FIG. 3, the reader device 15 repeatedly transmits the response request signal. When the tag TG receives the response request signal, the reader device 15 immediately returns the response signal R. do. The timing chart DR shown in FIG. 4 shows the reception status of the response signal R from the tag TG received by the reader device 15 in chronological order.
As described above, the response signal R received by the reader device 15 is not necessarily the one received from the tag TG existing in the wireless communicable area Q formed by the reader device 15. It is also assumed that the reader device 15 receives a response signal from a tag of a vehicle traveling in the lane adjacent to the lane L, for example, due to reflection of radio waves radiated by the reader device 15. That is, the response signal R shown in the timing chart DR also includes a response signal from a tag attached to a vehicle other than the vehicle that has entered the lane L.

The identification information acquisition unit 1001 of the lane control device 10 acquires the tag ID included in each response signal R by the processing of steps S01 to S02 of FIG. 3 for each of the response signals R shown in the timing chart DR. Record in the acquisition identification information table TB in association with the time (see FIG. 5).

Further, the vehicle detection signal D1A shown in FIG. 4 is a vehicle detection signal received from the vehicle detector 11A. Further, the vehicle detection signal D1B shown in FIG. 4 is a vehicle detection signal received from the vehicle detector 11B. When the vehicle A enters the lane L, it is "ON" in the order of the vehicle detection signal D1A → the vehicle detection signal D1B.

In the process of step S03 of FIG. 3, the vehicle detection signal acquisition unit 1002 determines whether or not the vehicle detection signal D1A → the vehicle detection signal D1B is “ON” in this order. When the vehicle detection signal D1A is "ON" at the time t1A and subsequently "ON" in the order of the vehicle detection signal D1B, the vehicle detection signal acquisition unit 1002 acquires the time t1B at that time.
In this case, the identification information specifying unit 1003 of the lane control device 10 calculates the time ta (= t1B−Δt) retroactive from the time t1B by a predetermined period Δt. Then, the identification information specifying unit 1003 refers to the acquisition identification information table TB of FIG. 5 and determines whether or not the acquisition time of each tag ID is included between the time ta and the time t1B. The identification information specifying unit 1003 extracts a tag ID whose acquisition time is between time ta and time t1B. When there are a plurality of tag IDs whose acquisition time is between the time ta and the time t1B, the identification information specifying unit 1003 has the tag ID acquired the latest among them (in the example shown in FIG. 5, "ID3". ”) Is specified. In such a case, in the process of step S06 of FIG. 3, the charge processing unit 1004 associates the tag ID (“ID3”) specified in step S05 with the charge amount and transmits the charge amount to the higher-level device.

If the acquired tag ID does not exist between the time ta and the time t1B in the acquisition identification information table TB, the identification information specifying unit 1003 cannot specify the tag ID to be charged (Fig.). Step 3 S04; NO). In this case, the charge processing unit 1004 activates the charge collection machine 12 and performs charge processing through the charge collection unit 12 (see steps S07 to S08 in FIG. 3).

(Action / effect)
As described above, the lane control device 10 (billing device) according to the first embodiment has a transmission unit 1000 that repeatedly transmits a response request signal to the wireless communicable region Q on the lane L via the reader device 15 and a reader. Communication with the identification information acquisition unit 1001 that acquires the tag ID (identification information) recorded in the tag TG (information recording medium) attached to the vehicle A, which is the information received by the device 15 as a response to the response request signal. The vehicle detection signal acquisition unit 1002 that acquires the vehicle detection signal from the vehicle detectors 11A and 11B arranged so as to be able to detect the vehicle A existing in the possible area Q, and the vehicle detection signal among the tag IDs acquired multiple times are acquired. Specified by the identification information specifying unit 1003 and the identification information specifying unit 1003 that specify the tag ID acquired within a predetermined period (between the time ta and the time t1B in FIG. 4) based on the timing (time t1B in FIG. 4). A billing processing unit 1004 that performs billing processing based on the tag ID is provided.
By doing so, among the tag IDs acquired a plurality of times, the tag ID acquired at approximately the same time as the timing at which the vehicle A to be charged is surely present in the wireless communication enable area Q is obtained by the vehicle A. It is possible to presume that it is the tag ID of the tag TG attached to and perform the billing process. Here, when a plurality of tags are present at different positions, the reader device 15 determines the tag ID included in the strongest response signal (that is, the tag ID recorded in the tag closest to the reader device 15). It has the characteristic of being easy to read. Therefore, the tag ID acquired at substantially the same time as the vehicle detection signal is acquired is the tag TG attached to the vehicle A (that is, the vehicle A to be charged) existing in the wireless communication enable area Q at that time. It is highly possible that the tag ID is recorded in. Therefore, it is estimated that the tag ID acquired at substantially the same time as the timing when the vehicle A to be charged is surely present in the wireless communication enable area Q is the tag ID of the tag TG attached to the vehicle A. Therefore, it is possible to increase the possibility that the vehicle A (the vehicle A existing in the wireless communicable area Q of the lane L) to be charged can be charged correctly.
From the above, according to the lane control device 10 according to the first embodiment, it is possible to provide a toll collection system in which erroneous billing is unlikely to occur.

Further, the lane control device 10 (billing processing unit 1004) according to the first embodiment charges processing through the toll receiving machine 12 installed in the lane L when the tag ID is not specified by the identification information specifying unit 1003. (See step S04; NO, step S07, and step S08 in FIG. 3).
By doing so, it is possible to charge the vehicle without the tag or the vehicle with a defect in the tag via the toll collection machine 12.

Further, the vehicle detection signal acquisition unit 1002 according to the first embodiment has vehicle detection signals D1A and D1B from each of the two vehicle detectors 11A and 11B arranged so as to be able to detect the vehicle existing in the communicable region Q. To get. Then, the identification information specifying unit 1003 identifies the tag ID when the vehicle detection signals are acquired from each of the two vehicle detectors 11A and 11B in a predetermined order.
In this way, by setting the order of the two vehicle detection signals as the determination condition, the billing process can be performed only when the vehicle enters correctly.

Further, the open / close control unit 1005 according to the first embodiment opens and controls the start controller 13 when the billing process is completed.
By doing so, when the billing process by the tag ID read through the reader device 15 is completed, the start controller 13 can be immediately opened and controlled, and the vehicle A can be exited from the lane L.

Here, the existing toll collection system includes a lane control device 10, vehicle detectors 11A and 11B, a toll collection device 12, a start controller 13, and a vehicle detector 14. However, at this stage, the lane control device 10 only has a function of billing processing through the toll collection device 12, and does not have a function related to billing processing using the reader device 15.

In manufacturing the toll collection system 1, the worker indicates that the wireless communicable area Q formed on the lane L is the detection position (positions X1, X2) of the vehicle detectors 11A and 11B with respect to the existing toll collection system. The reader device 15 is additionally installed so as to include.
Next, the operator adds functions as a transmission unit 1000, an identification information acquisition unit 1001, a vehicle detection signal acquisition unit 1002, and an identification information identification unit 1003 to the lane control device 10.

For example, the identification information specifying unit 1003 according to the first embodiment has been described as specifying the tag ID acquired between the time t1B at which the vehicle detection signal was acquired and the time ta retroactively by a predetermined period Δt. Other embodiments are not limited to this aspect.
For example, the identification information specifying unit 1003 according to another embodiment may specify the tag ID acquired between the time t1B and the time (t1B + Δt) when a predetermined period Δt has elapsed. Further, the identification information specifying unit 1003 according to another embodiment may specify the tag ID acquired during the period (time t1B−Δt1 to time t1B + Δt2, Δt1 + Δt2 = Δt) of a predetermined width (Δt) including the time t1B. ..

Further, when a plurality of tag IDs have been acquired during a predetermined period Δt, the identification information specifying unit 1003 according to the first embodiment identifies one of the latest acquired tag IDs. Although described as such, the other embodiments are not limited to this aspect. That is, as long as the identification information specifying unit 1003 has a function of specifying any one of the tag IDs among the plurality of tag IDs acquired during the predetermined period Δt, the method is any mode. It doesn't matter.
For example, in the identification information specifying unit 1003 according to another embodiment, when the tag ID is acquired a plurality of times during the predetermined period Δt, the tag acquired a plurality of times as the same tag ID from the tag ID is acquired. One ID may be specified. As a more specific example, the identification information specifying unit 1003 identifies one tag ID that is most frequently acquired as the same tag ID among the tag IDs acquired during the predetermined period Δt.
By doing so, on condition that the tag ID is acquired a plurality of times, it is regarded as the tag ID of the vehicle traveling in the lane, so that the possibility of erroneous billing can be further reduced.

Further, it has been explained that the toll collection system 1 according to the first embodiment determines the forward / backward movement of the vehicle based on the two vehicle detectors 11A and 11B installed on the upstream side of the lane L. In the embodiment of the above, the present invention is not limited to this aspect. For example, the toll collection system 1 according to another embodiment has only one vehicle detector on the upstream side of the lane L, and further, for forward / backward movement determination, another roadside device (for example, detection of pressure by a tire) is detected. It may be an embodiment using a possible tread plate or the like).

The process of each process in the lane control device 10 (billing device) described above is stored in a computer-readable recording medium in the form of a program, and the process is performed by the computer 500 reading and executing this program. Is done. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Further, the computer program may be distributed to the computer via a communication line, and the computer receiving the distribution may execute the program.

Further, the above program may be for realizing a part of the above-mentioned functions. Further, a so-called difference file (difference program) may be used, which can realize the above-mentioned function in combination with a program already recorded in the computer system.
Further, the lane control device 10 (billing device) may be composed of one computer or may be composed of a plurality of computers connected so as to be able to communicate with each other.

In addition, it is possible to replace the components in the above-described embodiment with well-known components as appropriate without departing from the spirit of the present invention. Further, the technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
