Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toll collection system for toll roads.

[0002]

2. Description of the Related Art Conventionally, in a toll road toll collection system, a toll collector directly receives cash from a driver at a tollgate, or a method in which a driver puts cash into an automatic machine to automatically receive a toll. Has been adopted. Therefore,
The driver had to stop at the toll booth and prepare cash.

On the other hand, as a toll collection system in the near future that does not require the delivery of cash at a tollgate, a vehicle such as a non-contact type IC card that records ID information and fee information and can wirelessly communicate with the outside is installed. A system has been developed in which a machine is mounted on a vehicle, wirelessly communicates with an external antenna, and collects a charge based on charge information of the vehicle-mounted device.

FIG. 3 is a perspective view of such a conventional fee collection system using radio. In the figure, a vehicle 1 travels in a lane 7 and enters a toll gate, and the vehicle 1 is equipped with an in-vehicle device 2. An ID number and amount data are recorded in the vehicle-mounted device 2, and wireless communication is performed with the antenna 3 on the road and the radio wave 8. A vehicle detector 4 detects passage of the vehicle 1 and transmits a vehicle detection signal 20 to the lane control device 5.
A display 6 displays charge information and the like.

In the toll collection system having such a configuration, the vehicle 1 traveling on the lane 7 of the toll road enters the toll gate, and the vehicle 1 passes and completes the vehicle detector 4 to complete the lane from the vehicle detector 4. The vehicle detection signal 20 is transmitted to the control device 5. Upon receiving the vehicle detection signal 20, the lane control device 5 emits a radio wave 8 from the antenna 3.

The vehicle-mounted device 2 mounted on the vehicle 1 has an antenna 3
When approaching, the radio wave 8 is received and the antenna 3 to the vehicle-mounted device 2 is received.
Wireless communication is performed between them, the ID number stored in the memory in the vehicle-mounted device 2 is checked in advance, and if normal, the toll is subtracted from the amount data of the vehicle-mounted device 2, and the remaining amount and the toll are displayed. By displaying in 6, the communication result is notified to the driver.

Further, as a result of checking the ID number, if the in-vehicle device 2 is reported to be lost or the amount of money is insufficient, the fact is displayed on the display device 6 to notify the driver.

[0008]

In such a conventional fee collection system, if the wireless communication between the antenna 3 and the vehicle-mounted device 2 is performed, the processing result is displayed on the display 6 immediately after that. Although it is possible to notify the driver, when a vehicle that does not have the in-vehicle device 2 or a vehicle in which the in-vehicle device 2 has a failure passes, wireless communication is not performed between the antenna 3 and the in-vehicle device 2, so the display device The processing result cannot be displayed in 6, and the driver is not notified.

In order to solve such a problem, the present invention provides a driver with a proper timing at a proper timing for a vehicle having no vehicle-mounted device or a vehicle in which the vehicle-mounted device has failed in a wireless communication fee collection system. The purpose is to provide a charge collection system that can be displayed.

[0010]

Therefore, the present invention comprises an antenna for wireless communication with a vehicle-mounted device, a vehicle detector for detecting an approaching vehicle, a display device, and a lane control device for controlling these, and lane control. The device measures the time when the vehicle enters and the in-vehicle device wirelessly communicates with the antenna.If wireless communication is not performed within the specified time, the vehicle that does not have the in-vehicle device or the in-vehicle device fails. It is configured to control so that it is considered that there is an abnormality and an error is displayed on the display.

That is, according to the present invention, an antenna which is installed on the road of a toll road toll road and carries out wireless communication with an in-vehicle device mounted on a vehicle and provided with wireless communication means, and enters the toll booth. A vehicle detector for detecting the entry of a vehicle, an indicator installed on the road of the tollgate for notifying the driver of the data communication result between the onboard unit and the antenna, and the antenna,
A lane control device that is connected to a vehicle detector and an indicator and controls them is provided, and the lane control device receives a vehicle approach signal from the vehicle detector, and within a predetermined time from the signal, It is measured whether or not the wireless communication between the antenna and the in-vehicle device is performed, and if the wireless communication is not performed within the same time, whether the in-vehicle device is not mounted in the entered vehicle,
Alternatively, a toll collection system for a toll road is provided, which is considered to be in failure and is controlled to display on the display.

[0012]

According to the present invention, when a vehicle enters by such means, the vehicle detector detects the entry and transmits the signal to the lane control device. When the lane control device receives this signal, it instructs the antenna, and the antenna emits an inquiry radio wave to the vehicle-mounted device. If there is no vehicle-mounted device in the vehicle, or if the vehicle-mounted device is out of order, wireless communication with the antenna is not performed, so the lane control device sets a fixed time from the time of entering the vehicle, and within this time If wireless communication is not performed, it is considered that there is no vehicle-mounted device or that the vehicle-mounted device has failed, and control is performed to display this fact on the display. The timing of this fixed time is

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a toll road toll collection system according to an embodiment of the present invention. In the figure, 1 is a vehicle traveling in a lane 7 and entering, 2 is a vehicle-mounted device mounted on the vehicle 1, 3 is an antenna installed on the roadside, and 4 is a vehicle detector for detecting the entry of the vehicle 1. Reference numeral 5 is a lane control device, 6 is a display device, 8 is a radio wave for wireless communication between the antenna 3 and the vehicle-mounted device 2, and 10 is a vehicle detection signal (entry) detected by the vehicle detector 4.

In the toll collection system having such a structure, the vehicle 1 traveling on the toll road enters the toll gate, and the vehicle 1 enters the vehicle detector 4, whereby the vehicle detector 4 moves to the lane control device 5. The vehicle detection signal (entry) 10 is transmitted. The lane control device 5 emits a radio wave 8 from the antenna 3 by receiving the vehicle detection signal (entry) 10.

The vehicle-mounted device 2 and the antenna 3 mounted on the vehicle 1
Wireless communication is performed with the vehicle, the ID number stored in the memory of the vehicle-mounted device 2 is checked in advance, and if normal, the toll is subtracted from the amount data of the vehicle-mounted device 2,
By displaying the remaining amount of money and the toll on the display device 6, the driver is notified of the communication result. Further, as a result of checking the ID number, in the case of an in-vehicle device that has been reported as lost, or if the amount of money is insufficient, that fact is displayed on the display device 6 to notify the driver.

Next, a detailed description will be given of the case of a vehicle that does not have the vehicle-mounted device 2 or a vehicle in which the vehicle-mounted device 2 is defective, which is a feature of the present invention. In FIG. 1, when a vehicle that does not have the vehicle-mounted device 2 or a vehicle in which the vehicle-mounted device 2 is faulty enters the vehicle detector 4, a vehicle detection signal (entry) 10 indicates a lane control device 5
And the radio wave 8 is emitted from the antenna 3. However, since the vehicle does not have the vehicle-mounted device 2 or is out of order, wireless communication with the antenna 3 is not performed, and the communication result cannot be displayed on the display unit 6, so the driver is notified. I can't.

Therefore, for such a vehicle, "A" is given for a certain period of time after the vehicle detection signal (entry) 10 is received.
When communication is not performed between the antenna 3 and the vehicle-mounted device 2 inside, it is determined that the vehicle does not have the vehicle-mounted device 2 or is a malfunctioning vehicle, and by displaying that fact on the display device 6, the driver However, it is difficult to determine “A” for a certain period of time depending on the running state of the vehicle (congestion, non-stop, etc.).

For example, during a rush hour in the morning and evening, if "A" is too short for a certain period of time, if a vehicle having a normal vehicle-mounted device 2 runs slowly, it is erroneously determined as a vehicle not having the vehicle-mounted device 2. In addition, when the traffic volume at night is small, non-stop high-speed driving is performed. Therefore, if "A" is too long for a certain period of time, the display device 6 is displayed on the vehicle without the vehicle-mounted device 2 or the vehicle that has failed. After passing, it is not possible to notify the driver because an abnormal message is displayed.

Therefore, the timing of the vehicle detection signal (entry) 10 and the result of wireless communication between the antenna 3 and the vehicle-mounted device 2 is measured, the running state of the vehicle is determined, and "A" is determined for a certain period of time. By doing so, the above-mentioned problem can be solved. A method of determining the fixed time "A" will be described below with reference to the timing chart of FIG.

FIG. 3 shows the vehicle detection signal (entry) 10 output from the vehicle detector 4 and the timing of wireless communication between the antenna 3 and the vehicle-mounted device 2. FIG. (B) is for low / medium speed running. In FIG. 3, x is a timing from the start of the vehicle detection signal (entry) 10 to the start of wireless communication, and this timing x has a different value depending on each vehicle or the traveling state of the vehicle. In general, the tamping during high-speed driving and low / medium-speed driving is x
The relationship is 1, x2 <x3, x4.

The lane control device 5 measures the two timings x for a vehicle having the onboard unit 2 to calculate and determine the value of "A" for a certain period of time. An example of the calculation formula is shown below.

[0023]

[Equation 1]

A is a coefficient, 1 ≦ a, and i is the number of items from the latest measurement data. "A" is calculated for a certain period of time by taking the average of the latest measurement data i for the timing x and multiplying by the coefficient a. If the constant time "A" is updated to a new value one after another, the timing x suitable for the running state of the vehicle can always be obtained. If wireless communication is performed at such a timing x, the vehicle-mounted device is not mounted. It is possible to determine the vehicle or the vehicle in which the vehicle-mounted device is out of order, and display that fact on the display unit 6.

In the toll collection system of this embodiment, the vehicle detector 4 detects the entry of the vehicle 1, and the timing of wireless communication between the vehicle detection signal (entry) 10, the antenna 3 and the vehicle-mounted device 2. Is measured by the lane control device 5, and the timing is averaged by the number of the latest measurement data to calculate "A" for a certain period of time. It is possible to display the abnormality information of the in-vehicle device on the display 6 by discriminating this even for a vehicle having no in-vehicle device or a vehicle in which the in-vehicle device has a failure without making any change only by bringing it closer to the area. It is possible to notify the driver.

[0026]

As described above in detail, the present invention comprises an antenna for wireless communication with an in-vehicle device, a vehicle detector for detecting an approaching vehicle, a display, and a lane control device for controlling these. The lane control device measures the timing until the vehicle enters and the in-vehicle device wirelessly communicates with the antenna.If wireless communication is not performed within a predetermined time, the vehicle or the in-vehicle device does not have an in-vehicle device. Since the configuration is such that it is regarded as a failure and is displayed on the display indicating that there is an abnormality, it is optimal for vehicles without an on-board unit or for a vehicle that does not have an on-board unit, without changing the conventional equipment configuration. It becomes possible to display at the display timing.
