Description

  Embodiments of the present invention relate to a toll collection system that automatically performs toll collection processing at a toll gate on a toll road.

  A fee collection system called an ETC (ETC: registered trademark) system (non-stop automatic fee collection system) has been put into practical use as a system using narrow-band wireless communication (DSRC: Dedicated Short-Range Communication).

  In the ETC system, an antenna device is installed on the toll collection lane of the toll booth to perform road-to-vehicle wireless communication with the on-vehicle device, and when a vehicle detector is installed on the side of the toll collection lane, Road-to-vehicle wireless communication is started with the vehicle-mounted device mounted on the vehicle. When wireless communication is completed normally, the vehicle can pass by opening the opening / closing bar of the start control device installed on the exit side of the toll collection lane, and the vehicle can perform toll collection processing non-stop. it can.

  In such an ETC system, when the road-to-vehicle wireless communication ends abnormally (communication failure), information necessary for the billing process is recorded on the ETC card (IC card) inserted (inserted) in the vehicle-mounted device. I can't.

In addition, when the wireless communication at the entrance toll gate ends abnormally, it is necessary to obtain a toll ticket, and it is necessary to perform payment processing using the toll ticket at the exit toll gate, making non-stop traffic impossible. .
In addition, since there is a manned response at the time of abnormal termination of wireless communication at the exit toll booth, it is necessary to improve the unmanned lane from the viewpoint of safety and efficiency, such as crossing the lane of the receiver.

  Therefore, recently, as a means for solving these problems, a second antenna device called a recovery antenna device has been installed. The implementation of the wireless communication retry with the recovery antenna device under consideration is the start of the operation of the recovery antenna device by touching the screen of the lane monitoring and control device installed at the tollgate or by operating a hard button.

  However, for example, when wireless communication with the first antenna device is abnormally terminated due to, for example, no ETC card inserted into the vehicle-mounted device, a guidance display that prompts the vehicle to stop is displayed on the roadside display device and the vehicle is temporarily stopped. Then, in order to guide to the communication position of the recovery antenna device and further perform wireless communication similar to that of the first antenna device using the recovery antenna device, it is necessary to give an instruction or operation of a receiving person (person).

  If the guidance display prompting the vehicle to stop after the guidance display prompting the vehicle to stop is performed, no response will be made to the receiver, but if the timing is too early, the stop instruction will be confirmed. Since the guidance display is performed without the vehicle, the vehicle may pass and collide with the opening / closing bar of the start control device.

Hereinafter, a fee collection system according to an embodiment will be described with reference to the drawings.
FIG. 1 schematically shows a configuration of a toll collection system (ETC system) at an exit toll gate of the distance charging method according to the embodiment.

  In FIG. 1, 11 is a toll collection lane (road) of a toll booth, and it is assumed that the vehicle 12 enters in the direction of the arrow a in the figure. It is assumed that the vehicle-mounted device 13 is mounted on the vehicle 12. An IC card called an ETC card for toll collection is attached to the in-vehicle device 13. In the memory in the ETC card, for example, OBE information (vehicle number as vehicle management information, vehicle type information, OBE number as OBE specific information, etc.), entrance information, exit information, billing information, etc. are recorded. .

  On the entrance side of the toll collection lane 11, a first vehicle detection device 14 that detects an entering vehicle 12, a vehicle that is installed at a predetermined distance away from the first vehicle detection device 14 and that travels downstream. The second vehicle detection device 15 that detects the vehicle 12 and the roadside display device that is installed at a predetermined distance away from the second vehicle detection device 15 and displays various types of guidance on the vehicle 12 traveling on the lane 11. 16, an interphone 17 installed in the vicinity of the roadside display device 16 and having a conversation with a receiver in the toll booth; a vehicle installed at a predetermined distance downstream from the roadside display device 16 and exiting from the lane 11 12, a start control device (passage control means) 18 for controlling permission and prohibition of traffic, and a third device that detects a vehicle 12 that is installed at a predetermined distance downstream from the start control device 18 and leaves. Both sensing device 19 are respectively provided.

  Above the toll collection lane 11, a first antenna device 20 corresponds to the second vehicle detection device 15, and a recovery antenna device 21 as a second antenna device corresponds to the front of the start control device 18. , Each is installed.

  The first antenna device 20 forms a communication area (communication position) 20 a at a predetermined position on the toll collection lane 21, and performs road-to-vehicle wireless communication with the vehicle-mounted device 13 mounted on the vehicle 12. The in-vehicle device information is acquired and billing information is transmitted to the device 13.

  The recovery antenna device 21 operates when the wireless communication by the first antenna device 20 ends abnormally, forms a communication area (communication position) 21a at a predetermined position of the toll collection lane 11, and the first antenna device 20 Instead, by performing road-to-vehicle wireless communication with the vehicle-mounted device 23 mounted on the vehicle 22, the vehicle-mounted device 23 acquires vehicle-mounted device information and transmits billing information and the like.

  The roadside display device 16 is installed at a predetermined position between the first antenna device 20 and the recovery antenna device 21.

  First vehicle detection device 14, second vehicle detection device 15, roadside display device 16, interphone 17, start control device 18, third vehicle detection device 19, first antenna device 20, and recovery antenna device 21 Are connected to a lane server 22 that controls these and executes various processes such as a toll collection process.

  The lane server 22 is provided with a guidance display timer (timer means) 23. As will be described in detail later, the guidance display timer 23 instructs the roadside display device 16 to display guidance for stopping the vehicle 12, and then instructs the guidance display to guide the communication position of the recovery antenna device 21. The time until is set.

The lane server 22 is connected to a supervisory control device 24 for a receiver to remotely monitor each lane. The lane server 22 is connected to a host device (management device) (not shown) via a communication line.
The lane server 22 and the monitoring control device 24 are installed in a toll booth 25, for example.

Next, the operation of the fee collection system configured as described above will be described.
First, the flow of processing when a normal vehicle (an ETC card insertion vehicle in which an ETC card is inserted into the vehicle-mounted device 13) enters will be described with reference to the flowchart shown in FIG.

  When the first vehicle detection device 14 detects the entry of the vehicle 12 (step S1), the lane server 22 turns on (operates) the first antenna device 20, and the vehicle-mounted device 13 mounted on the vehicle 12 By performing wireless communication via the first antenna device 20, the vehicle-mounted device information and the entrance information are acquired, and a check process is performed to check whether the acquired information is correct or not. (Step S2), and notifies the in-vehicle device 13 and the monitoring control device 24 of the processing results (step S3).

  In the check process in step S2, it is assumed that whether or not an ETC card is inserted in the vehicle-mounted device 13 is also checked. Checking whether or not the ETC card is inserted in the on-vehicle device 13 includes, for example, information on whether or not the ETC card is inserted in the on-vehicle device information acquired from the on-vehicle device 13, and the ETC card is determined by the information on whether or not the ETC card is inserted. It is determined whether or not it has been inserted. In this case, since the ETC card insertion presence / absence information is “present”, it is determined that the ETC card is inserted, and the vehicle is determined to be a normal vehicle.

  Next, when the second vehicle detection device 15 detects the entry of the vehicle 12 (step S4), the lane server 22 instructs the roadside display device 16 to display the calculated usage fee and the guidance indicating that the vehicle can pass. (Step S5) After that, the start control device 18 is instructed to start (gate open) (Step S6).

  Next, when the third vehicle detection device 19 detects the entry of the vehicle 12 (step S7), the lane server 22 instructs the roadside display device 16 to delete the guidance display (step S8).

  Next, when the third vehicle detection device 19 detects the exit of the vehicle 12 (step S9), the lane server 22 instructs the start control device 18 to stop (gate close) (step S10).

  Note that if two normal vehicles 12 have entered in succession, until the preceding vehicle 12 finishes entering or leaving the third vehicle detection device 19, Processing result notification and guidance display instruction to the roadside display device 16 are not performed.

  In addition, even if the preceding vehicle 12 leaves the third vehicle detection device 19, if the subsequent vehicle 12 has entered the second vehicle detection device 15, a stop (gate closing) instruction to the start control device 18. Does not.

  Next, the flow of processing when an abnormal vehicle (an ETC card non-inserted vehicle into which the ETC card is not inserted into the vehicle-mounted device 13) enters will be described with reference to the flowcharts shown in FIGS.

  When the first vehicle detection device 14 detects the entry of the vehicle 12 (step S11), the lane server 22 turns on (operates) the first antenna device 20, and the on-vehicle device 13 mounted on the vehicle 12 By performing wireless communication via the first antenna device 20, the vehicle-mounted device information is acquired, and a check process for checking the correctness of the acquired information is performed (step S12). The control device 24 is notified (step S13).

  In the check process in step S12, it is also assumed that whether or not an ETC card is inserted in the vehicle-mounted device 13 is also checked. Checking whether or not the ETC card is inserted in the on-vehicle device 13 includes, for example, information on whether or not the ETC card is inserted in the on-vehicle device information acquired from the on-vehicle device 13, and the ETC card is determined by the information on whether or not the ETC card is inserted. It is determined whether or not it has been inserted. In this case, since the ETC card insertion presence / absence information is “None”, it is determined that the ETC card is not inserted, it is determined that the vehicle is abnormal, and wireless communication abnormally ends.

  Next, when the second vehicle detection device 15 detects the entry of the vehicle 12 (step S14), the lane server 22 instructs the roadside display device 16 to stop the guidance display timer 23. It is turned on (counting operation) (step S15).

  Here, FIG. 5A shows a specific example of the guidance display indicating the stop to be displayed on the roadside display device 16. In the specific example of FIG. 5A, since the number of characters displayed on the roadside display device 16 is limited, for example, one display message 31 is divided into three messages 31a, 31b, and 31c, which are indicated by arrows in the figure. The case where it displays repeatedly sequentially is shown. The message 31a guides and displays "4 wheel STOP stop, 2 wheel ETC evacuation", the message 31b guides and displays "no card information", and the message 31c displays "back prohibition".

  Next, when the guidance display timer 23 counts up (step S <b> 16), the lane server 22 performs guidance guidance display for guiding the vehicle 12 to the communication position of the recovery antenna device 21 on the roadside display device 16. (Step S17) The driver of the vehicle 12 is instructed to insert the ETC card into the vehicle-mounted device 13 from the receiver in the booth 25 via the interphone 17 (Step S18).

  Here, a specific example of the guidance display displayed on the roadside display device 16 is shown in FIG. In the specific example of FIG. 5B, since the number of characters displayed on the roadside display device 16 is limited, for example, one display message 32 is divided into two messages 32a and 32b, which are sequentially repeated as shown by the arrows in the figure. The case of displaying is shown. The message 32a displays a message “Proceed here” and the message 32b displays a message “I will communicate again”.

  When the start of recovery is instructed via the monitoring control device 24 by the button operation of the receiver in the booth 25, the lane server 22 turns on (operates) the recovery antenna device 21 and is mounted on the vehicle 12 In-vehicle device information and entrance information are acquired by performing wireless communication via the on-vehicle device 13 and the recovery antenna device 21, and the acquired information is checked. If normal, the usage fee is collected for the vehicle 12. The processing is performed (step S19), and the processing result is notified to the vehicle-mounted device 13 and the monitoring control device 24 (step S20).

  Next, the lane server 22 instructs the roadside display device 16 to display the calculated usage fee and guidance indicating that the vehicle can pass (step S21), and then instructs the start control device 18 to start (open the gate). Is performed (step S22).

  Next, when the third vehicle detection device 19 detects the entry of the vehicle 12 (step S23), the lane server 22 instructs the roadside display device 16 to delete the guidance display (step S24).

  Next, when the third vehicle detection device 19 detects the exit of the vehicle 12 (step S25), the lane server 22 instructs the start control device 18 to stop (gate close) (step S26).

  If a normal vehicle 12 and an abnormal vehicle (vehicle not inserted with an ETC card) 12 enter continuously, the preceding normal vehicle 12 has entered or exited the third vehicle detection device 19. When the guidance display timer 23 is turned on and the guidance display timer 23 counts up, the vehicle 12 is connected to the roadside display device 16 with the recovery antenna. The guidance guidance display for guiding to the communication position of the apparatus 21 is performed. Thereafter, the same processing as described above is performed.

  The guidance display timer 23 determines the time until the guidance display instruction for guiding to the communication position of the recovery antenna device 21 is given after the guidance display to stop the vehicle 12 is given to the roadside display device 16. The set time is variable and can be easily changed. The guidance display timer 23 can adjust the display time for guidance display to stop and the timing until guidance display for guiding to the communication position of the recovery antenna device 21 is performed.

  Normally, the roadside display device 16 has a limit on the number of characters that can be displayed at one time. Therefore, when displaying a long message, it is necessary to display while switching to a plurality of screens. In general, the display time of one screen and the screen switching time are determined by the roadside display device 16.

  For example, the display time for one screen is 0.9 seconds and the screen switching time is 0.3 seconds. For example, when all the messages shown in FIG. Second + (3 times switching) × 0.3 seconds = 3.6 seconds are required. If the time of the guidance display timer 23 is set based on this time, the number of times the message is displayed can be determined. Further, even if the display time or switching time of the roadside display device 16 is changed, it can be easily handled by changing the set time of the guidance display timer 23.

  Further, the installation position of the roadside display device 16 is not uniform due to the installation space and the like. Generally, the installation position of the third vehicle detection device 19 can be broadly classified into three patterns: an upstream position (before the traveling direction), a downstream position (traveling direction destination), and other special positions.

  When the roadside display device 16 is installed on the upstream side of the third vehicle detection device 19, the approaching vehicle 12 is already in the vicinity, so if the guidance instruction is not given immediately after the stop instruction, the vehicle 12 will pass. There is a possibility.

  When the roadside display device 16 is installed on the downstream side of the third vehicle detection device 19, the guidance display may not be seen well until the approaching vehicle 12 approaches, and both the stop instruction and the guidance instruction are displayed. In order to be recognized, it is necessary to delay the guidance indication display.

  When the roadside display device 16 is installed at a special position, it is desirable to individually adjust the time when the approaching vehicle 12 can recognize both the stop instruction and the guidance instruction.

  When there is a preceding vehicle, the guidance display for the following vehicle is switched by entering the third vehicle detection device 19, which can be changed by entering or leaving the third vehicle detection device 19. In such a case, if the guidance display of the guidance instruction for the following vehicle is performed early, it may be confused with the instruction to the preceding vehicle, so the guidance display of the guidance instruction needs to be delayed.

  The guidance display for guiding the vehicle 12 to the communication position of the recovery antenna device 21 is performed on a vehicle without an ETC card inserted into the vehicle-mounted device 13 but other vehicles other than the vehicle with no ETC card inserted. Even in the case of an abnormal vehicle or a non-ETC vehicle not equipped with the vehicle-mounted device 13, it is necessary to come to the vicinity of the interphone 17 in order to have a conversation with the receiver for performing the subsequent processing. It is effective to switch the guidance display of the roadside display device 16 by using the control according to.

  In the above description, the toll collection system at the exit toll gate of the distance charging method is described as an example, but the toll collection system at the entrance toll gate of the distance charging method or the exit (entrance) toll gate of the uniform fee charging system. The same applies to the toll collection system.

  According to the toll collection system of at least one embodiment described above, the guidance display instruction for guiding to the communication position of the recovery antenna device 21 after instructing the roadside display device 16 to display the guidance to stop the vehicle 12 By making variable the time until guidance (guidance display timer 23), it is possible to adjust the display time for guidance display to stop and the timing until guidance display for guiding to the communication position of the recovery antenna device 21. it can.

  In addition, by making the guidance display timer 23 variable, stop instructions and guidance instructions can be displayed at just the right timing according to the installation position of the roadside display device 16, the positional relationship with the preceding vehicle, and the display erasing timing of the preceding vehicle. Can be adjusted.

  Therefore, a recovery process can be performed for a vehicle in which wireless communication has ended abnormally, in particular, an ETC card non-inserted vehicle.

  In addition, when the guidance display for guiding the vehicle to the communication position of the recovery antenna device is performed immediately after the guidance display that prompts the vehicle to stop, as in the past, if the timing is too early, the stop instruction is not confirmed. Since the guidance display is performed, there is a risk that the vehicle passes and collides with the opening / closing bar of the start control device. However, according to the embodiment, such a situation can be prevented.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
