Description

  The present invention relates to a fee collection system and a fee collection method.

An electronic toll collection system (ETC: Electronic Toll Collection System (registered trademark)) that collects tolls via on-board devices installed in vehicles and collects tolls via electronic payment as a system for collecting tolls on toll roads Also known as “automatic toll collection system”).
On toll roads, different tolls may be charged depending on the type of vehicle (for example, "light car", "normal car", "medium-sized car", "large car", or "extra-large car") Therefore, the vehicle type classification of the vehicle is registered in advance in the in-vehicle device. However, for example, depending on whether the vehicle is towing a towed vehicle such as a trailer, the vehicle type classification is higher or lower than the vehicle classification registered in the vehicle-mounted device (ranking up or down) ) Therefore, in the automatic toll collection system, for example, an axle sensor that counts the number of axles of the vehicle is provided, and the actual vehicle type classification of the vehicle based on the number of axles (the vehicle type that is ranked up or down depending on the presence or absence of the towed vehicle) Classification).

In addition, charging methods for toll roads include a distance toll system that charges different tolls depending on the vehicle type and distance, and a uniform toll system that charges a fixed toll for each vehicle type.
On toll roads that use the distance toll system, the toll gate facility including the above-mentioned axle sensor and the antenna that can communicate with the vehicle-mounted device is installed at the entrance toll gate, and the vehicle type classification is based on the number of axles. In addition to the determination, the vehicle type classification and entrance information indicating which entrance toll road has entered the toll road may be written to the vehicle-mounted device via an antenna (see, for example, Patent Document 1). The exit toll gate is provided with an antenna capable of communicating with the vehicle-mounted device, and the vehicle type classification and the entrance information written at the entrance toll gate are acquired via the antenna. The exit toll gate collects a toll fee according to the vehicle type classification determined at the entrance toll gate and the distance from the entrance toll gate indicated by the entrance information. As a result, in the automatic toll collection system in the distance toll system, toll collection processing can be performed based on the actual vehicle type classification determined at the entrance toll gate without determining the vehicle type classification at the exit toll gate. it can.
On the other hand, on toll roads that adopt the uniform toll system, the axle sensor and antenna as described above are installed at either the entrance toll gate or the exit toll gate to determine the actual vehicle type classification of the vehicle and Collect tolls determined by category. For example, on a toll road that collects tolls by installing an axle sensor and antenna at the exit toll gate, these devices are not installed at the entrance toll gate, and the vehicle can enter the toll road without slowing down or stopping. There are cases.

JP 2011-233089 A

There are cases where the toll road charging system is changed from the flat fee system to the distance toll system in accordance with the guidelines from the government.
In the conventional automatic toll collection system applied to the distance toll system, it is necessary to discriminate the vehicle type at the entrance toll gate. However, as described above, the axle sensor There is a case where a device for discriminating the vehicle type is not provided. For this reason, when the charging method is changed from the flat fee system to the distance fee system, it is necessary to add a device to each of the entrance toll gates. Furthermore, depending on the location conditions of the entrance toll gate, it may be difficult to secure a space for installing the equipment.

In order to secure equipment installation space and reduce costs, it is also conceivable to apply a system (free flow system) in which only an antenna is installed at an entrance toll booth to perform wireless communication with a vehicle. At this time, entrance information acquired via the antenna is recorded in the vehicle-mounted device.
However, in the conventional automatic toll collection system applied to the distance toll system, the vehicle type classification is not determined at the exit toll gate, but the vehicle type classification determined at the entrance toll gate is acquired from the vehicle-mounted device. For this reason, when only the antenna is installed at the entrance toll booth, it becomes impossible to obtain the actual vehicle type classification of the vehicle at the exit toll booth. As a result, when the vehicle classification changes depending on the presence or absence of the towed vehicle, it may be difficult to collect an appropriate toll for the actual vehicle classification of the vehicle.

  The present invention has been made in view of such problems, and a toll collection system capable of collecting tolls according to the vehicle type classification of a vehicle while reducing the installation space and cost of equipment at an entrance toll gate And provide a toll collection method.

In order to solve the above problems, the present invention employs the following means.
According to one aspect of the present invention, a toll collection system (1) that collects tolls with an in-vehicle device that is provided at an exit toll gate of a toll road and is mounted on a vehicle traveling in a lane is the vehicle. A tread board (12) for detecting a stepping by the vehicle and outputting a detection signal capable of specifying the number of axles of the vehicle, and a discrimination process for discriminating the vehicle type of the vehicle based on the number of axles and outputting the first vehicle type classification A vehicle type discriminating device (10) having a section (13), a first antenna (22) for performing wireless communication with the vehicle-mounted device in a first communication area defined on the downstream side of the lane with respect to the tread, Wireless communication with the vehicle-mounted device in a second communication region defined downstream of the first communication region in the lane and at a position where the vehicle-mounted device can arrive after the vehicle passes through the tread. The second antenna (23 And through the first antenna, the vehicle information is obtained from the in-vehicle device, through the first antenna, the entrance information indicating the entrance toll gate where the vehicle has entered the toll road, and the second vehicle type classification indicating the vehicle type of the vehicle. And determining the toll based on the information acquisition unit (241) for acquiring the first vehicle type classification from the device, the entrance information, the first vehicle type classification, and the second vehicle type classification; A charge determining unit (242) for writing the toll to the vehicle-mounted device through the first antenna and the second antenna. The toll determination unit determines the toll based on the first vehicle type classification when the entrance information indicates an entrance toll gate where the vehicle type cannot be determined, and if the entrance information indicates an entrance toll gate capable of determining the vehicle type, The toll is determined based on the second vehicle type classification.
By having such a configuration, the toll determination unit can obtain the first vehicle type classification acquired from the vehicle type determination device and the first acquired from the vehicle-mounted device, depending on from which entrance toll gate the vehicle has entered the toll road. The toll can be determined based on either one of the two vehicle types. Thereby, even if the vehicle type classification of the vehicle changes depending on the presence or absence of the towed vehicle, the toll determination unit will determine the toll based on the actual vehicle type classification determined at either the entrance toll gate or the exit toll gate Therefore, it is possible to collect an appropriate toll for the actual vehicle type classification of the vehicle.
Further, when the distance toll system is adopted at the entrance toll gate where the vehicle type discrimination device is not installed, in the conventional toll collection system, a vehicle type discrimination device must be newly installed at the entrance toll gate. However, in the toll collection system according to the above-described aspect, the actual vehicle type classification can be determined by the vehicle type determination device at the exit toll gate, so that it is not necessary to newly install a vehicle type determination device at the entrance toll gate. For this reason, it is possible to adopt the distance toll system even in a narrow entrance toll gate where a space for installing the vehicle type identification device cannot be secured. Furthermore, the cost for installing equipment at the entrance toll gate can be reduced.

According to the second aspect of the present invention, the fee collection system according to the above-described aspect further includes an antenna control unit (243) that controls activation of the second antenna. The antenna control unit indicates an entrance toll gate where the entrance information cannot be discriminated from the vehicle type, and when the vehicle enters the downstream side of the lane from the first communication area, the information acquisition unit If the vehicle type classification is not acquired, the second antenna is activated.
By having such a configuration, even if the vehicle length is long and the on-board unit cannot acquire the first vehicle type classification before leaving the first communication area, the toll collection system By activating the antenna, communication can be performed between the second antenna and the vehicle-mounted device in the second communication area.
In addition, when the entrance information indicates a place other than the entrance toll gate where the vehicle type cannot be identified, or when the first vehicle type classification can be acquired while the vehicle-mounted device is located in the first communication area, the antenna control unit Since the two antennas are not activated, it is possible to reduce the possibility that unnecessary communication is performed between the second antenna and the vehicle-mounted device and a communication abnormality occurs.

According to a third aspect of the present invention, in the toll collection system according to any one of the above aspects, the toll determination unit indicates an entrance toll gate where the entrance information cannot be discriminated, and the vehicle is the first toll If the information acquisition unit has not acquired the first vehicle type classification when entering the downstream side of the lane from one communication area, the toll is written to the on-vehicle device via the second antenna. .
By having such a configuration, even if the vehicle length is long and the vehicle-mounted device cannot acquire the first vehicle type classification before leaving the first communication area, The toll can be written in the vehicle-mounted device via the antenna. That is, the toll determining unit can write the toll on the vehicle-mounted device via the second antenna even if the toll determining unit determines the toll after waiting for the vehicle type discrimination device to complete the discrimination of the vehicle type. For this reason, the fee determining unit can determine an appropriate toll for the actual vehicle type classification of the vehicle determined by the vehicle type determining device.

According to the fourth aspect of the present invention, the toll collection system according to any one of the above aspects stores in advance toll gate information indicating whether or not the vehicle type classification of the vehicle can be determined at each of the entrance toll gates. And a storage unit (244). When the toll gate information associated with the entrance information indicates that the vehicle type classification cannot be determined, the toll determination unit determines that the entrance information indicates an entrance toll gate where the vehicle type cannot be determined.
By having such a configuration, the toll determination unit can determine whether or not the entrance information indicates an entrance toll gate where the vehicle type cannot be determined based on the toll gate information.

  According to the fifth aspect of the present invention, a toll collection method for collecting tolls with an onboard device mounted on a vehicle traveling in a lane at an exit toll gate on a toll road is a stepping on the vehicle. A vehicle type determination step of specifying the number of axles of the vehicle based on a detection signal output from the tread plate (12) to be detected, determining the vehicle type of the vehicle based on the number of axles, and outputting the vehicle type as a first vehicle type classification A first communication step of performing wireless communication with the vehicle-mounted device by a first antenna (22) in a first communication region defined on the downstream side of the lane with respect to the tread, and from the first communication region In a second communication area defined downstream of the lane and at a position where the vehicle-mounted device can arrive after the vehicle has passed through the tread board, the vehicle is wirelessly connected to the vehicle-mounted device by a second antenna (23). A second communication step for performing communication, entrance information indicating an entrance toll gate where the vehicle has entered the toll road from the vehicle-mounted device, and a second vehicle type classification indicating the vehicle type of the vehicle via the first antenna And acquiring the information based on the information acquisition step for acquiring the first vehicle type classification determined in the vehicle type determination step, the entrance information, the first vehicle type classification, and the second vehicle type classification. A charge determining step of determining a toll and writing the toll on the vehicle-mounted device via the first antenna and the second antenna. The toll determination step determines the toll based on the first vehicle type classification when the entrance information indicates a vehicle type where the vehicle type cannot be determined, and the entrance information indicates other than the entrance toll gate capable of determining the vehicle type The toll is determined based on the second vehicle type classification.

  According to the toll collection system and the toll collection method according to the present invention, it is possible to collect a toll according to the vehicle type classification of the vehicle while reducing the installation space and cost of the equipment at the entrance toll gate.

The signal N6 (FIG. 2) is output.

(Functional configuration of toll collection system)
FIG. 2 is a diagram showing a functional configuration of a fee collection system according to an embodiment of the present invention.
Hereinafter, the functional configuration of the fee collection system 1 will be described with reference to FIG.
As shown in FIG. 2, the toll collection facility 100 of the toll collection system 1 includes a vehicle type identification device 10, a toll collection device 20, a roadside indicator 30, a start controller 40, and a start detector 50. ing.
The vehicle type determination device 10 includes a first vehicle detector 11, a tread 12, and a determination processing unit 13. The toll collection device 20 includes a second vehicle detector 21, a first antenna 22, a second antenna 23, and a control unit 24.

In the first vehicle detector 11, the vehicle A is present at the position where the first vehicle detector 11 is arranged in the lane direction (± X direction in FIG. 1) (that is, the upstream end of the first communication area Q1). The vehicle detection signal N1 indicating whether or not is output to the discrimination processing unit 13 and the toll collection device 20.
Further, when the tread 12 detects a step by the tire of the vehicle A, the tread detection that can specify the number of axles of the vehicle A (that is, the number of times the tread 12 has been stepped on by the tire), the tread width, and the tire width. The signal N2 is output to the discrimination processing unit 13.

  Based on the vehicle detection signal N1 and the stepping detection signal N2, the determination processing unit 13 specifies the feature information (the number of axles, the tread width, the tire width, etc.) of the vehicle A, and also determines the vehicle A based on the feature information. The vehicle type division M1 (first vehicle type division) is determined. The determination processing unit 13 outputs the determined vehicle type classification M1 of the vehicle A to the toll collection device 20.

  The second vehicle detector 21 has the vehicle A at the position where the second vehicle detector 21 is arranged in the lane direction (± X direction in FIG. 1) (that is, the downstream end of the first communication area Q1). A vehicle detection signal N3 indicating whether or not is output to the control unit 24.

  The control unit 24 includes an information acquisition unit 241, a charge determination unit 242, an antenna control unit 243, and a storage unit 244.

The information acquisition unit 241 uses the history information R1 including the entrance information M2 indicating the entrance toll gate where the vehicle A enters the toll road and the vehicle type division M3 (second vehicle type division) indicating the vehicle type of the vehicle A as the first information. Obtained from the vehicle-mounted device α mounted on the vehicle A via the antenna 22. In addition, the information acquisition unit 241 acquires the vehicle type classification M1 output from the vehicle type identification device 10.
In the present embodiment, the entrance information M2 and the vehicle type division M3 are obtained by performing wireless communication between the antenna provided at the entrance toll gate and the vehicle-mounted device α, so that the vehicle-mounted device α (more specifically, the vehicle-mounted device α). IC card inserted in the device α).

FIG. 3 is a diagram for explaining functions of a fee collection system according to an embodiment of the present invention.
For example, as shown in FIG. 3, when a plurality of entrance toll gates T2, T3, T4,... Are provided between an entrance toll gate T1 that is the start point of the toll road and an exit toll gate Tn that is the end point. To do. In addition, the toll road includes a flat fee section (for example, from the entrance toll gate T1 to the entrance toll booth T4) in which a flat fee system is adopted, and a distance-toll distance section (for example, an entrance fee) in which a distance fee system is employed. From the point T4 to the end point). A toll collection facility 80 including a vehicle type discriminating device 81 and an antenna 82 is provided at the entrance toll booth T4 in the distance toll zone, but a car type discriminating device and an antenna are provided at the entrance toll gates T1 to T3 in the uniform toll zone. It is assumed that no such equipment is provided.
When the distance toll system is adopted in all sections (T1 to Tn) of such toll roads, in this embodiment, for example, at the entrance toll gate T4 where the toll collection facility 80 is already provided, additional equipment is added. The existing vehicle type discriminating device 81 and the antenna 82 are used as they are without any change. Note that the vehicle type discriminating apparatus 81 and the antenna 82 of the toll collection facility 80 have the same configuration as the vehicle type discriminating apparatus 10 and the first antenna 22 of the toll collection facility 100, and thus the description thereof is omitted. For this reason, when the vehicle A enters from the entrance toll gate T4, the vehicle type classification M3 of the vehicle A is determined by the vehicle type determination device 81 of the toll collection facility 80. Then, through the antenna 82 of the toll collection facility 80, the entrance information M2 indicating the entrance toll booth T4 and the vehicle type classification M3 determined by the vehicle type determination device are written in the vehicle-mounted device α of the vehicle A. That is, when the vehicle A enters from the entrance toll gate T4 provided with the vehicle type discriminating device 81, the vehicle type classification M3 that the information acquisition unit 241 acquires from the vehicle-mounted device α is ranked up or ranked depending on the presence or absence of the towed vehicle. Down is reflected.
For this reason, in the entrance toll gate T4 that can discriminate the vehicle type by the vehicle type discriminating device 81, the vehicle-mounted device α is not the vehicle type classification registered in advance when the on-vehicle device α is set up, but is actually discriminated by the vehicle type discriminating device 81. The vehicle type division (the vehicle type division that is ranked up or down according to the presence or absence of the towed vehicle) is recorded as the vehicle type division M3.

On the other hand, at the entrance toll gates T2 to T3 where the toll collection facility 81 is not provided, only the antenna 82 that can wirelessly communicate with the vehicle-mounted device α is newly installed when adopting the distance fee system. Furthermore, the installation of the antenna 82 is omitted at the entrance toll gate T1, which is the starting point. The antenna 82 has the same configuration as that of the antenna 82 of the toll collection facility 80, and a description thereof will be omitted.
In the entrance toll gates T2 to T3, since the vehicle type cannot be determined by the vehicle type determination device, information indicating the actual vehicle type classification is not written in the vehicle-mounted device α, and only the entrance information M2 is written. In this case, the vehicle-mounted device α outputs the vehicle type division registered in advance when the vehicle-mounted device α is set up as the vehicle type division M3 when performing wireless communication with the first antenna 22 of the exit toll gate. That is, when the vehicle A enters from the entrance toll gates T1 to T3 where the vehicle type identification device 81 is not provided, the vehicle type classification M3 acquired by the information acquisition unit 241 from the vehicle-mounted device α is ranked up depending on the presence or absence of the towed vehicle. Or rank down is not reflected.
Further, at the entrance toll gate T1 where no antenna is installed, the entrance information M2 and the vehicle type division M3 are not recorded in the vehicle-mounted device α. However, since only the entrance toll gate T1 has no antenna installed on this toll road, in the toll collection facility 100 at the exit toll gate, when the entrance information M2 is not recorded in the vehicle-mounted device α, the vehicle A It is possible to specify that the vehicle has entered from the entrance toll gate T1.
In another embodiment, an antenna 82 may be installed at the entrance toll gate T1.

  Further, the information acquisition unit 241 is used for an electronic payment process of “vehicle-mounted device ID” that is an identification number for identifying the vehicle-mounted device α, “vehicle number” of the vehicle A in which the vehicle-mounted device α is mounted, and toll charges. “Card ID” may be further acquired. “Onboard equipment ID” and “vehicle number” are information registered in advance in a storage unit (not shown) of the onboard equipment α at the time of setup of the onboard equipment α, and “Card ID” is inserted into the onboard equipment α. This is information registered in the IC card.

The fee determining unit 242 determines the toll M4 for the vehicle A based on the vehicle type division M1, the entrance information M2, and the vehicle type division M3 acquired by the information acquisition unit 241.
Specifically, the toll determination unit 242 refers to the tollgate information D1 stored in the storage unit 244 and determines whether or not the entrance information M2 indicates “entrance tollgate where the vehicle type cannot be determined”. .
FIG. 4 is a diagram showing an example of toll gate information according to an embodiment of the present invention.
As shown in FIG. 4, in the toll gate information D1, information indicating whether or not the vehicle type can be determined for each entrance toll gate is registered. For example, information indicating that the vehicle type cannot be determined (“impossible”) is registered because no vehicle type determination device is installed at the entrance toll gates T1 to T3. In addition, since the vehicle type discrimination device 81 is installed at the entrance toll gate T4, information ("OK") indicating that the vehicle type can be discriminated is registered.
When the entrance information M2 indicates “entrance toll gate where the vehicle type cannot be identified”, the vehicle type division M3 acquired from the on-vehicle device α is a vehicle type division registered in the on-vehicle device α at the time of setup. In this case, since the vehicle type division M3 may be different from the actual vehicle type division (vehicle type division reflecting rank up or down depending on the presence or absence of the towed vehicle), the fee determining unit 242 acquires the vehicle type division from the vehicle type identification device 10. A toll M4 is determined based on the vehicle type division M1.
On the other hand, when the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type”, the vehicle type classification M3 acquired from the vehicle-mounted device α is the vehicle type classification determined by the vehicle type identification device 81 at the entrance toll gate. In this case, since the vehicle type division M3 indicates an actual vehicle type division, the toll determination unit 242 determines the toll M4 based on the vehicle type division M3 acquired from the onboard device α.
The fee determining unit 242 may determine the toll by referring to a predetermined fee table for each combination of entrance toll gate and vehicle type classification.
In addition, the fee determining unit 242 writes the history information R1 including the determined toll M4 to the vehicle-mounted device α via the first antenna 22 and the second antenna 23. Furthermore, the toll determination unit 242 outputs the toll M4 to the roadside display 30 and causes the roadside display 30 to present the amount of the toll M4 to the user.
The fee determining unit 242 creates detailed information including the toll M4 and various information (such as a card ID) acquired by the information acquiring unit 241 and transmits the detailed information to a central management server (not shown). The electronic payment processing of the toll for the vehicle A is performed.

The antenna control unit 243 includes the vehicle detection signal N1 and the vehicle type classification M1 output from the vehicle type determination device 10, the vehicle detection signal N3 output from the second vehicle detector 21, and the entrance information M2 acquired by the information acquisition unit 241. Based on the above, activation and deactivation of the first antenna 22 and the second antenna 23 are controlled.
When the antenna control unit 243 receives the vehicle detection signal N1 from the vehicle type identification device 10 (first vehicle detector 11) and detects that the vehicle A (on-vehicle device α) has arrived at the first communication area Q1, The first antenna 22 is activated (radio wave emission is turned on). Further, by receiving the vehicle detection signal N3 from the second vehicle detector 21, the vehicle A (the vehicle-mounted device α) enters the downstream side in the lane direction (the −X side in FIG. 1) from the first communication region Q1. That is, when it is detected that the user has left the first communication area Q1, the first antenna 22 is stopped (radio wave radiation is turned off).
Further, the antenna control unit 243 indicates that when the entrance information M2 indicates “the entrance toll gate where the vehicle type cannot be identified” and the vehicle A leaves the first communication area Q1, the information acquisition unit 241 When the vehicle type division M1 is not acquired, the second antenna 23 is activated. The antenna control unit 243 stops the second antenna 23 when detecting that the vehicle A (the vehicle-mounted device α) has exited the second communication area Q2 by receiving the exit detection signal N5 from the start detector 50. To do.

  In the storage unit 244, the toll gate information D1 shown in FIG. 4 is stored in advance. The storage unit 244 may store a charge table in advance.

(Processing flow of antenna control processing)
FIG. 5 is a first diagram showing a processing flow of the fee collection system according to the embodiment of the present invention.
Hereinafter, the flow of the antenna control process in the antenna control unit 243 of the charge collection apparatus 20 in the process flow of the charge collection system 1 will be described with reference to FIG.
First, when receiving the vehicle detection signal N1 from the vehicle type identification device 10 (first vehicle detector 11) (step S100), the antenna control unit 243 activates the first antenna 22 (step S101).

  Next, the information acquisition unit 241 of the toll collection device 20 receives the history information R1 including the entrance information M2 indicating the entrance toll gate where the vehicle A entered the toll road and the vehicle type division M3 via the first antenna 22. Obtained from the vehicle-mounted device α mounted on the vehicle A (step S102).

Next, the antenna control unit 243 refers to the toll gate information D1 (FIG. 4) stored in the storage unit 244 and determines whether or not the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type” ( Step S103).
For example, when the entrance information M2 indicates the entrance toll gate T4, the antenna control unit 243 refers to the toll gate information D1 and determines that the entrance toll gate T4 “can discriminate the vehicle type” (step S103: YES). On the other hand, for example, when the entrance information M2 indicates the entrance toll gate T3, the antenna control unit 243 refers to the toll gate information D1 and determines that the entrance toll gate T3 “cannot discriminate the vehicle type” (step S103: NO). .

When the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type” (step S103: YES), the vehicle type classification M3 acquired from the vehicle-mounted device α is the actual vehicle type classification determined by the vehicle type identification device 81 of the entrance toll gate. is there. In this case, the fee determining unit 242 can immediately execute the process of determining the toll M4 based on the vehicle type division M3 and writing it to the vehicle-mounted device α without waiting for the determination result by the vehicle type determining device 10. For this reason, the antenna control unit 243 determines that the activation of the second antenna 23 is unnecessary, and proceeds to the next step without activating the second antenna 23.
And the antenna control part 243 will stop the 1st antenna 22 (step S105), and will complete | finish an antenna control process, if the vehicle detection signal N3 is received from the 2nd vehicle detector 21 (step S104).

In addition, when the entrance information M2 indicates “entrance toll gate that cannot discriminate the vehicle type” (step S103: NO), the vehicle type division M3 acquired from the on-vehicle device α is not an actual vehicle type division but is registered in advance when setting up the on-vehicle device α. This is a classified vehicle type. In this case, the toll determination unit 242 must wait until the vehicle type classification M1 determined by the vehicle type determination device 10 at the exit toll booth is acquired, and then perform processing for determining the toll M4. However, when the vehicle length of the vehicle A is long, all the tires of the vehicle A do not pass through the tread 12 before the vehicle-mounted device α (the head portion of the vehicle A) exits the first communication area Q1. 10 may not be completed.
For this reason, when the entrance information M2 indicates “entrance toll gate where the vehicle type cannot be determined”, the antenna control unit 243 depends on the position of the vehicle A on the lane L and the timing at which the vehicle type determination of the vehicle type determination device 10 is completed. Then, it is determined whether or not the second antenna 23 is activated.
Specifically, first, the antenna control unit 243 determines whether or not the vehicle detection signal N3 is received from the second vehicle detector 21 (step S106).
When the vehicle detection signal N3 is not received (step S106: NO), the antenna control unit 243 waits until the vehicle detection signal N3 is received. Further, when the antenna control unit 243 receives the vehicle detection signal N3 (step S106: YES), the vehicle A (on-vehicle device α) leaves the first communication area Q1 and cannot communicate with the first antenna 22. It is determined that the first antenna 22 is stopped (step S107).

When the vehicle detection signal N3 is received and the first antenna 22 is stopped, the antenna control unit 243 determines whether or not the vehicle type division M1 has been acquired from the vehicle type determination device 10 (step S108). When the antenna control unit 243 receives the vehicle detection signal N3, that is, when the vehicle A (the vehicle-mounted device α) has left the first communication area Q1, the vehicle type division M1 has been acquired (step S108: YES). ), The charge determining unit 242 determines that the process of determining the toll M4 based on the vehicle type division M1 has been completed, and determines that the activation of the second antenna 23 is unnecessary. For this reason, the antenna control unit 243 ends the antenna control process without activating the second antenna 23.
Further, when the vehicle control signal N3 is not acquired and the antenna control unit has not acquired the vehicle type division M1 (step S108: NO), the antenna control unit regards that the processing in the fee determining unit 242 has not been completed, and the second antenna 23 Is activated (step S109).

When the antenna control unit 243 activates the second antenna 23 and then receives the exit detection signal N5 (step S110), the vehicle A (vehicle equipment α) exits the second communication area Q2 and Therefore, the second antenna 23 is stopped (step S111). Then, the antenna control unit 243 ends the antenna control process.
The antenna control unit 243 repeatedly executes the antenna control process described above every time the vehicle enters the lane L.

(Processing flow for fee determination processing)
FIG. 6 is a second diagram showing a processing flow of the fee collection system according to the embodiment of the present invention.
Hereinafter, with reference to FIG. 6, the flow of the charge determination process in the charge determination unit 242 of the charge collection device 20 in the process flow of the charge collection system 1 will be described.
First, the information acquisition unit 241 of the toll collection device, when the vehicle A (the vehicle-mounted device α) arrives at the first communication area Q1, the entrance information M2 indicating the entrance toll gate where the vehicle A entered the toll road, and the vehicle type classification History information R1 including M3 is acquired from the vehicle-mounted device α via the first antenna 22 (step S200).

Next, the fee determining unit 242 refers to the toll gate information D1 (FIG. 4) stored in the storage unit 244 to determine whether or not the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type” ( Step S201).
When the entrance information M2 indicates “entrance toll gate (for example, entrance toll gate T4) that can discriminate the vehicle type” (step S201: YES), the vehicle type classification M3 acquired from the vehicle-mounted device α is discriminated by the vehicle type discriminating device 81 of the entrance toll gate. This is the actual vehicle type classification. In this case, the fee determining unit 242 determines the toll M4 of the vehicle A based on the vehicle type division M3 acquired from the vehicle-mounted device α without waiting for the determination result by the vehicle type determining device 10 (step S202).
Further, when the fee determining unit 242 writes the history information R1 including the determined toll M4 to the vehicle-mounted device α via the first antenna 22 (step S203), the fee determining process is terminated.

On the other hand, when the entrance information M2 indicates “entrance toll gate (for example, entrance toll gate T3) where the vehicle type cannot be identified” (step S201: NO), the vehicle type division M3 acquired from the vehicle-mounted device α is not an actual vehicle type division but an on-vehicle type. It is a vehicle type division registered in advance when the device α is set up. In this case, the charge determination unit 242 performs a charge determination process based on the vehicle type classification M1 acquired from the vehicle type determination device 10 in order to calculate an accurate toll based on the actual vehicle type classification.
Specifically, the fee determining unit 242 determines whether or not the vehicle type classification M1 is acquired from the vehicle type identification device 10 (step S204).
If the vehicle type division M1 has not been acquired (step S204: NO), the fee determining unit 242 waits until the vehicle type division M1 is acquired.
Moreover, when the vehicle type division M1 is acquired (step S204: YES), the fee determination unit 242 determines the toll M4 for the vehicle A based on the vehicle type division M1 (step S205).

And the charge determination part 242 will determine whether the vehicle A (vehicle equipment (alpha)) is located in the 1st communication area | region Q1, if the toll F4 is determined (step S206).
The charge determining unit 242 determines when the vehicle A is located in the first communication area Q1 (step S206: YES), that is, when the vehicle detection signal N3 is not received from the second vehicle detector 21. The history information R1 including the toll M4 is written to the vehicle-mounted device α via the first antenna 22 (step S203), and the charge determination process is terminated.
On the other hand, the charge determination unit 242 determines when the vehicle A is not located in the first communication area Q1 (step S206: NO), that is, when the vehicle detection signal N3 is received from the second vehicle detector 21. The history information R1 including the toll M4 is written to the vehicle-mounted device α via the second antenna 23 (step S207), and the charge determination process is terminated.
The charge determination unit 242 repeatedly executes the above charge determination process every time the vehicle enters the lane L.

(Function and effect)
As described above, the toll collection system 1 according to the present embodiment collects tolls with the vehicle-mounted device α installed in the vehicle A traveling on the lane L, provided at the exit toll gate of the toll road. The toll collection system 1 detects a stepping by the vehicle A and outputs a stepping detection signal N2 that can specify the number of axles of the vehicle, and determines the vehicle type of the vehicle A based on the number of axles. The vehicle type discriminating apparatus 10 having the discrimination processing unit 13 that outputs as the vehicle type division M1 (first vehicle type division) and the vehicle-mounted device α and the radio in the first communication area Q1 defined downstream of the lane L from the tread 12 A first antenna 22 that performs communication, and a second downstream of the lane L from the first communication area Q1 and defined at a position where the vehicle-mounted device α can arrive after the vehicle A passes through the tread 12. In the communication area Q2, the vehicle-mounted device α and The second antenna 23 for performing line communication, the entrance information M2 indicating the entrance toll gate where the vehicle A entered the toll road from the vehicle-mounted device α, and the vehicle type division M3 (second vehicle type division) indicating the vehicle type of the vehicle A The toll M4 is determined based on the information acquisition unit 241 that acquires the vehicle type division M1 from the vehicle type identification device 10, the entrance information M2, the vehicle type division M1, and the vehicle type division M3. In addition, a charge determination unit 242 that writes the toll M4 to the vehicle-mounted device α via the first antenna 22 and the second antenna 23 is provided. When the entrance information M2 indicates “entrance toll gate that cannot discriminate the vehicle type”, the toll determination unit 242 determines the toll M4 based on the vehicle type classification M1 acquired from the vehicle type discriminating apparatus 10, and the entrance information M2 is “the vehicle type can be discriminated. When “entrance toll gate” is indicated, the toll M4 is determined based on the vehicle type division M3 acquired from the vehicle-mounted device α.
By having such a configuration, the toll determination unit 242 acquires from the vehicle type classification M1 acquired from the vehicle type discriminating apparatus 10 and the in-vehicle device α according to which entrance toll road the vehicle A entered the toll road. The toll M4 can be determined based on one of the vehicle type divisions M3. That is, the toll determination unit 242 passes based on the actual vehicle type classification determined at either the entrance toll gate or the exit toll gate even when the vehicle type classification of the vehicle A changes depending on the presence or absence of the towed vehicle. Since the charge M4 can be determined, it is possible to collect an appropriate toll for the actual vehicle type classification of the vehicle A. At this time, when the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type”, the toll determination unit 242 determines the toll M4 based on the vehicle type division M3 acquired from the vehicle-mounted device α. The fee determination process can be terminated without waiting for the vehicle type classification to be completed. For this reason, it is possible to increase the processing speed in the charge determination unit 242.
Further, when the distance toll system is adopted at the entrance toll gate where the vehicle type discriminating device 81 is not installed, in the conventional toll collection system, the vehicle type discriminating device 81 must be newly installed at the entrance toll gate. However, in the toll collection system 1 according to the present embodiment, the vehicle type discriminating device 10 at the exit toll gate can discriminate the actual vehicle type division (vehicle type division M1), so a vehicle type discriminating device 81 is newly added at the entrance toll gate. There is no need to install. For this reason, it is possible to adopt the distance toll system even in a narrow entrance toll gate where a space for installing the vehicle type identification device 81 cannot be secured.
Furthermore, since only the antenna 82 has to be installed at the entrance toll gate as in the entrance toll gates T2 to T3 in FIG. 3, the cost for installing the equipment can be reduced. Moreover, even if the entrance information M2 is not recorded as in the entrance toll booth T1 in FIG. 3, the antenna 82 may be omitted if it can be specified that the entrance toll road has entered from the entrance toll booth T1. Good. Thereby, the cost for installing an apparatus can further be reduced.

The fee collection system 1 according to the above-described embodiment further includes an antenna control unit 243 that controls activation of the second antenna 23. The antenna control unit 243 indicates that the entrance information M2 indicates “the entrance toll gate where the vehicle type cannot be identified” and the information acquisition unit 241 sets the vehicle type when the vehicle A enters the downstream side of the lane L from the first communication area Q1. When the vehicle type division M1 is not acquired from the determination device 10, the second antenna 23 is activated.
By having such a configuration, even if the vehicle A is long and the vehicle-mounted device α cannot acquire the vehicle type division M1 before leaving the first communication area Q1, the toll collection system 1 By activating the second antenna 23, communication can be performed between the second antenna 23 and the vehicle-mounted device α in the second communication region Q2.
In addition, when the entrance information M2 indicates “entrance toll gate capable of discriminating the vehicle type”, or when the vehicle type classification M1 can be acquired from the vehicle type discriminating apparatus 10 while the vehicle-mounted device α is located in the first communication area Q1. Since the antenna control unit 243 does not activate the second antenna 23, it is possible to reduce the possibility that unnecessary communication is performed between the second antenna 23 and the vehicle-mounted device α to cause a communication abnormality.

In the toll collection system 1 according to the above-described embodiment, the toll determination unit 242 indicates that the entrance information M2 indicates “the entrance toll gate where the vehicle type cannot be identified”, and the vehicle A is in the lane L more than the first communication area Q1. When the information acquisition unit 241 does not acquire the vehicle type classification M1 from the vehicle type identification device 10 when entering the downstream side of the vehicle, the toll M4 is written in the vehicle-mounted device α via the second antenna 23.
By having such a configuration, even if the vehicle length of the vehicle A is long and the vehicle-mounted device α cannot acquire the vehicle type division M1 before leaving the first communication area Q1, the fee determining unit 242 The toll M4 can be written in the vehicle-mounted device α via the second antenna 23. That is, the toll determination unit 242 writes the toll M4 to the vehicle-mounted device α via the second antenna 23 even if the toll determining unit 10 determines the toll M4 after waiting for the vehicle type discriminating apparatus 10 to complete the discrimination of the vehicle type classification M1. be able to. For this reason, the fee determining unit 242 can determine an appropriate toll M4 for the actual vehicle type classification (vehicle type classification M1) of the vehicle A determined by the vehicle type identification device 10.

The toll collection system 1 according to the above-described embodiment further includes a storage unit 244 that stores in advance toll gate information D1 indicating whether or not the vehicle type classification can be determined in each of the entrance toll gates. When the toll gate information D1 associated with the entrance information M2 indicates that the vehicle type classification cannot be determined, the toll determination unit 242 determines that the entrance information M2 indicates “the entrance toll gate where the vehicle type cannot be determined”.
By having such a configuration, the toll determination unit 242 can easily and quickly determine whether or not the entrance information M2 indicates “the entrance toll gate where the vehicle type cannot be determined” based on the toll gate information D1.

As mentioned above, although embodiment of this invention was described in detail, unless it deviates from the technical idea of this invention, it is not limited to these, A some design change etc. are possible.
For example, in the above-described embodiment, the description has been given of the aspect in which the information indicating whether or not the vehicle type can be determined for each entrance toll gate is registered in the toll gate information D1, but the present invention is not limited to this. In another embodiment, only the “entrance toll gate that cannot discriminate the vehicle type” may be registered in the toll gate information D1. Then, when the entrance toll gate indicated by the entrance information M2 is registered in the toll gate information D1, the toll determination unit 242 may determine that the entrance toll gate cannot discriminate the vehicle type. By doing so, it is possible to reduce the information amount of the tollgate information D1 and simplify the processing in the toll determination unit 242.

  Further, in the above-described embodiment, the discrimination processing unit of the vehicle type discrimination device 10 is based on the vehicle detection signal N1 received from the first vehicle detector 11 and the stepping detection signal N2 received from the tread 12. Although the aspect which specified the feature information and discriminate | determined the vehicle classification M1 was demonstrated, it is not restricted to this. In another embodiment, the vehicle type identification device 10 includes a license plate reading device that outputs a detection signal that can specify the license plate information (number plate number, plate size, etc.) of the vehicle A, the vehicle length, and the vehicle height. You may have further a detector and a vehicle height detector. And the discrimination | determination processing part 13 pinpoints the feature information (number plate information, vehicle length, vehicle height) of the vehicle A based on the vehicle detection signal N1, the stepping detection signal N2, and the detection signal received from these apparatuses. Then, the vehicle type division M1 may be determined. Thereby, the accuracy of the discrimination processing of the vehicle type division M1 in the discrimination processing unit 13 can be improved. Note that these devices can be added or omitted depending on the installation space of the exit toll gate.
