[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a nonstop automatic toll collection system (ETC system) according to a first embodiment of the toll collection system of the present invention.

In FIG. 1, reference numeral 1 denotes a vehicle. A license plate is fixed to a front bumper portion, which is the foremost portion of the vehicle 1, as means for distinguishing the vehicle for each individual. A wireless tag 4 for vehicle identification is fixed to the back of the license plate, the inside of the license plate, or the body of the vehicle 1 so as not to be detachable. The front panel of the vehicle 1 has ET
The in-vehicle device 2 for the C system is attached. In addition,
The vehicle on which the vehicle-mounted device 2 is mounted is referred to as an ETC vehicle 1.

The wireless tag 4 comprises a nonvolatile memory element such as an EEPROM, for example, a memory chip, and an antenna coil which resonates with a radio signal of a predetermined frequency and transmits data of the memory chip as a response. The information (vehicle number (vehicle-specific information), external dimensions, weight, type, etc.) of the vehicle as described in the vehicle verification is irrevocably stored in the memory chip. The license plate including the wireless tag 4 is called an “IC number”. In this example, an example is described in which the IC number is attached to the front bumper portion of the vehicle 1. However, the IC number is attached to the rear bumper portion of the vehicle 1. There is also.

The vehicle-mounted device 2 includes a CPU, a memory, a card slot, a display unit, a wireless communication unit, and the like. An IC card 3 used for payment of a fee is mounted in the card slot. At the start of use of the vehicle-mounted device, information unique to the vehicle and information specific to the vehicle-mounted device are recorded in advance in the memory. The information unique to the vehicle and the information unique to the vehicle-mounted device are collectively referred to as vehicle-mounted device information. The vehicle-specific information includes license plate information, the number of axles of the vehicle, vehicle length, vehicle height, and information for identifying a vehicle toll category.

The IC card 3 is provided with a nonvolatile storage element such as an EEPROM. This EEPRO
In M, for example, personal information of a user, a payment account number, an expiration date, and the like are stored in advance as settlement information relating to toll payment. And entrance information when using toll road,
Exit information, payment history information, and the like are stored in the EEPROM.

The IC card 3 is used as a means for specifying a toll payment account. When the vehicle 1 travels on the toll road, the IC card 3 is mounted on the vehicle-mounted device 2 in advance, and the toll paid by wireless communication with the on-road device at the toll gate is paid.

The wireless tag 4 records at least the registration number and the number of axes of the vehicle registration information. The information of the wireless tag 4 is read by the wireless tag sensor 7 installed on the road surface. The wireless tag 4 records registration information of an actual vehicle at the time of a vehicle registration procedure or the like, and thereafter, the registration information is read-only.

In the vehicle-mounted device 2, auxiliary information (vehicle identification code and the like) for determining the number of axes of the vehicle, a vehicle number, and a toll classified by vehicle type is recorded in advance. The wireless tag 4 records the same registration number information as the license plate at the time of vehicle registration and almost the same information (vehicle number, width, height, length, registration date, etc.) as the vehicle verification.

The ETC lanes installed at the tollgate (toll gate) for the vehicle 1 to enter or exit from the toll road include a plurality of lanes from the vehicle entrance lane to allow the vehicle 1 to pass efficiently. Often branched.

In each lane, a vehicle detector 5, an axis detector 6,
A wireless tag sensor 7, an antenna 8, and a system control unit 10 are provided.

The vehicle detector 5 is a photoelectric sensor in which a light-emitting unit and a light-receiving unit are arranged opposite to each other at an entrance portion of each lane with an interval enough to allow one vehicle to pass through. The presence of an object (vehicle) that has blocked the light beam (such as infrared light).

The axis detector 6 is a load sensor which is disposed at substantially the same position (when viewed in the traveling direction of the vehicle) as the vehicle detector 5 in each lane and substantially facing the road surface. The direction of the axle of the vehicle passing through the position of the container 6 is detected. The term “substantially facing the road surface” means that when the sensor has a tread plate shape, the sensor may slightly protrude from the road surface. In some cases, a sensor buried in a road is used, and these states are collectively referred to.

The wireless tag sensor 7 is configured such that the vehicle 1
Alternatively, it is arranged to be able to communicate with the wireless tag 4 immediately before or at the time of detection by the vehicle detector 5.

Thus, the output of the vehicle detector 5 and the output of the wireless tag sensor 7 are correlated. Therefore, the shaft detector 6 is arranged at substantially the same position as the vehicle detector 5 so as to produce the same effect.

The antenna 8 is approximately 5 m from the road surface of each lane.
And a communication area (radio wave transmission range) for about one vehicle in the lane width and the vehicle traveling direction at a position between the vehicle detector 5 and the gate exit. Designed. The antenna 8 is connected to the system control unit 10
Is controlled by

The system control unit 10 receives the detection information from the sensors such as the vehicle detector 5 and the wireless tag sensor 7, specifies the lane in which the vehicle 1 has entered, and controls the antenna 8 of the specified lane to be mounted on the vehicle. It performs processing such as acquisition of device information, comparison of vehicle-specific information acquired by different wireless communication means, determination of the vehicle, and toll collection. Further, the system control unit 10 measures (detects) the number of axles of the passing vehicle 1 by processing the number of axles detected by the axle detector 6 and the output of the vehicular detector 5, for example.

Hereinafter, the operation of the ETC system of this embodiment will be described with reference to the flowchart of FIG. This E
In the TC system, when the vehicle 1 enters the lane to the toll gate at the entrance or exit of the toll road, the wireless tag sensor 7 detects the vehicle 1 (S101), and the wireless tag sensor 7
Communication with the wireless tag 4 fixed to the license plate on the front portion of the vehicle 1 is performed, and information unique to the vehicle is acquired by the system control unit 10 through the wireless tag sensor 7 (S102).

At about the same time, the front end portion (front portion) of the vehicle 1 is detected by the vehicle detector 5, and the system controller 10 is notified of the entry of the vehicle 1 into the own lane.

As a result, the system control unit 10 controls the antenna 8, and the communication connection between the antenna 8 and the vehicle-mounted device 2 is started (S103).

Subsequently, the measurement of the axle is started when the front wheel (first axle) of the vehicle 1 is mounted on the axle detector 6 (S10).
4). By the time the front wheel (first shaft) of the vehicle 1 passes through the shaft detector 6, the reading of the information of the wireless tag 4 is completed, and the information from the wireless tag 4 is transmitted to the system control unit 10.

The system control unit 10 includes a registration number of the vehicle 1 included in information of the vehicle-mounted device 2 (vehicle-mounted device information) received by wireless communication between the antenna 8 and the vehicle-mounted device 2, a wireless tag sensor 7, and a wireless tag 4. The wireless tag sensor 7 compares the received vehicle registration number with the vehicle registration number, and if they match (match) with each other (Yes in S105), the communication processing between the vehicle-mounted device of the vehicle 1 and the antenna 8 is continued to pass. The process proceeds to a process for determining a fee payment method (S106).

On the other hand, if the vehicle registration numbers do not match (non-conformity) (No in S105), the system control unit 10 determines that the communication partner has not been identified or that the communication with the vehicle-mounted device 2 is different from the vehicle. Since it is assumed that the state of the communication is cleared and a notification to the effect of the collection staff is made,
Return to waiting for vehicle detection.

In the toll calculation process, the system control unit 10 transmits necessary information (entrance information,
User's personal information, payment account number, card ID, etc.) are extracted from the vehicle-mounted device information and temporarily stored in a memory to prepare for charging.

When the vehicle 1 has passed the position of the axis detector 6, the measurement of the number of axes by the system control unit 10 is completed (S107). Is determined by comparing the number of axles of the vehicle included in the on-vehicle device information acquired from step S10 (S10).
8).

Here, when there is no mismatch in the number of axes (S10)
8), the system control unit 10 determines that the vehicle that has entered the lane and the vehicle equipped with the vehicle-mounted device 2 with which the antenna 8 has communicated are the same vehicle (the vehicle is correct), and The toll is charged according to the information on the payment method temporarily stored in (S109).
The information of the charging result is transmitted to the vehicle-mounted device 2, the exit gate (e.g., the start control device) is opened, and the process ends.

On the other hand, if the number of axes does not match (S1
(No at 08), it is determined that the vehicle entering the lane is different from the vehicle equipped with the on-vehicle device 2 with which the antenna 8 communicates (abnormal), and the clerk is notified of the abnormality as a clerk handling process (S110). ), The exit gate (e.g., the start control device) is closed, the abnormality is notified to the vehicle-mounted device 2, and the process is terminated.

As described above, according to the ETC system of this embodiment, when the vehicle 1 enters the ETC lane, first, the wireless tag sensor 7 installed on the road surface of the lane is fixed to the body of the vehicle 1. When vehicle-specific information such as a vehicle number is detected from the wireless tag 4 and passed to the system control unit 10, the system control unit 10 specifies a vehicle type and a lane from the acquired vehicle-specific information and controls the antenna 8. Vehicle 1
Since the vehicle-mounted device information is acquired from the vehicle-mounted device 2 mounted on the vehicle and the data such as the vehicle number included in the vehicle-mounted device information is compared with the vehicle number acquired from the wireless tag 4, the validity of the vehicle 1 is determined. Of the lanes, the toll can be correctly received without misidentifying the vehicle 1 entering the own lane.

Further, when the vehicle-mounted device 2 is replaced or when the vehicle-mounted device 2 or the antenna 8 does not operate normally, at least information on the vehicle can be obtained from the wireless tag 4. Payment processing (toll collection) with the card 3 can be performed.

That is, information is acquired from two vehicle information holding means (wireless tag 4 and on-vehicle device 2) attached to different portions of the vehicle 1 (the front portion and the inside of the vehicle) to determine the lane and the vehicle type in which the vehicle 1 has entered. Since the ETC process is performed after the identification, the system can cope with the case where the vehicle-mounted device 2 is replaced or the radio wave state of the antenna 8 is unstable.

In other words, even if the antenna 8 on the road on which the system relies, the vehicle 1 entering the own lane can be identified and the vehicle 1 can be erroneously recognized even when the radio wave of the vehicle-mounted device 2 is received from another lane. Can be performed without causing the ETC.

The present invention is not limited only to the above embodiment. The communication start control and the end control with the vehicle sensor such as the wireless tag sensor 7 need not necessarily be the above operation example. A necessary requirement is that vehicle-specific information be obtained from the wireless tag 4 by the first half of the communication area of the antenna 8.

In the above embodiment, the timing for ending the reading of the information of the wireless tag 4 is determined by the first timing of the vehicle 1.
Although the time when the shaft has passed the position of the shaft detector 6 is set, the predetermined time may be set after the end of the vehicle 1 is detected by the vehicle detector 5, for example.

[0043]

As described above, according to the present invention, the vehicle entering the own lane is specified based on the vehicle-specific information obtained from the wireless tag fixed to the vehicle, and the vehicle is mounted on the vehicle. By checking the compatibility with the vehicle-specific information acquired from the on-vehicle device, a correct fee can be received without mistaking a vehicle in another lane and a vehicle entering the own lane. In addition, the system can cope with, for example, a case where the vehicle-mounted device is replaced or a problem with the wireless equipment on the road, and the vehicle can be collected at a correct fee.
