Description

  The present invention relates to a gate opening / closing system, a gate opening / closing device, and a gate opening / closing control method for opening / closing a gate through which a vehicle passes, for example, in a parking lot or a toll road.

  Systems that charge by providing gates at parking lots and entrances of toll roads are widely used. Recently, vehicles equipped with in-vehicle devices that have wireless communication units and information storage units such as IC cards. An automatic toll collection system that opens and closes a gate by performing charging processing by wireless communication such as DSRC (Dedicated Short Range Communication) between a roadside device and a vehicle-mounted device is becoming widespread.

  In this type of automatic toll collection system, if there are multiple vehicles near the gate, the communication wave propagates over a wide range due to the effects of multipath, etc., and is a vehicle different from the nearest vehicle that should be charged originally The billing process may be performed by communicating with the in-vehicle device. In particular, when installing an automatic toll collection system in indoor or underground parking lots, communication waves are often reflected and many vehicles are likely to be present in a narrow area. The impact will increase. In such a case, there is a possibility that when a vehicle that has been previously charged enters, it may be charged twice in the immediate vicinity of the gate, and countermeasures are required.

  As a method of reducing multipath, the directivity of the antenna of the roadside device is limited to limit the range of communication waves radiated from the roadside device to the in-vehicle device, or above the area where the vehicle passes, such as a lane. Although there is a method of reducing the reflection of communication waves by providing a radio wave absorber, the automatic toll collection system becomes expensive.

  As a technique for reducing processing errors due to interference between front and rear vehicles in the toll collection system, for example, the detection means such as an optical sensor detects the tip of the vehicle and the number of axles, and the start and stop of wireless communication are controlled by detecting the vehicle. (See Patent Document 1).

  In addition, as a technique for preventing toll collection of tolls in the toll collection system, for example, by reading the number plate of the vehicle detected by the vehicle detection device and comparing the number of this number plate with the vehicle number management table, A system for discriminating between paid vehicles and unpaid vehicles has been proposed (see Patent Document 2).

  In the above conventional example, processing errors are prevented by limiting the communication time by detecting the vehicle, or the charging status of the corresponding vehicle is discriminated by reading the license plate to prevent double charging and uncollected charges. However, when there was a gate, there was no control associated with the gate operation.

  Recently, the introduction of a so-called electronic license plate in which storage means such as an IC chip is mounted on a license plate of a vehicle so that more information about the vehicle can be held and utilized has been studied. It would be convenient if the plate could be applied to a toll collection system.

  Next, as a first embodiment, a first example of operation in the gate opening / closing system will be described. First, an outline of the operation in the first embodiment will be described. The roadside device 10 of the first embodiment reads the ID information of the in-vehicle device 30 and the vehicle information of the electronic license plate 40, and the vehicle information of both the in-vehicle device 30 and the electronic license plate 40 matches, so that the same vehicle In some cases, charging processing is executed. That is, when the vehicle on which the in-vehicle device 30 that has started communication for the charging process is mounted is positioned immediately before the gate 20 and the electronic license plate 40 is read, the charging process is performed. After completing the billing process, the bar 21 is driven to open the gate 20 and pass the vehicle.

  Next, the gate opening / closing operation procedure in the gate opening / closing system of the first embodiment will be described in detail. FIG. 4 is a flowchart showing an operation procedure in the gate opening / closing system according to the first embodiment. This gate opening / closing operation is mainly executed by the control of the control unit 17 of the roadside apparatus main body 11.

  When the vehicle 51 immediately before the gate 20 is detected by the vehicle sensor A13 (step S11), the control unit 17 of the roadside apparatus main body 11 sends an instruction to the communication unit 15 to start wireless communication, and within the communication area. Transmission / reception is performed to / from a certain in-vehicle device 30 (step S12). Normally, communication is performed with the vehicle-mounted device 30 mounted on the detected vehicle 51, but when there are a plurality of vehicles in the vicinity of the gate 20, the vehicle is mounted on the vehicle 52 at a slightly separated position due to the influence of multipath or the like. Communication may be performed with the in-vehicle device 30 that has been used.

  Then, the ID information of the in-vehicle device 30 of the communication partner is read (step S13). At the same time, an instruction is sent to the electronic number reading device 25, and the electronic number reading device 25 reads the vehicle information of the electronic number plate 40 of the vehicle 51 immediately before the gate 20 (step S14). Next, the two pieces of acquired information are compared to determine whether or not these pieces of vehicle information match (step S15). Thereby, it can be confirmed whether the vehicle equipped with the vehicle-mounted device 30 that has started communication is the same as the vehicle of the read electronic license plate 40. Here, when vehicle information does not correspond, communication with the vehicle-mounted apparatus 30 is cut | disconnected (step S16), and it returns to step S11 and waits until the next vehicle is detected.

  If the vehicle information acquired in step S16 matches, the control unit 17 performs a billing process regarding gate passage with the in-vehicle device 30 as the communication partner (step S17). This billing process is a process for paying a parking lot usage fee, a road toll, and the like, and performs processing related to collection of value related to authentication of ID information of an in-vehicle device (or vehicle) and payment. For actual settlement, various settlement modes such as prepaid, postpaid, and simultaneous payment can be taken using the IC card 39 of the in-vehicle device 30. Therefore, confirmation of ID information, fee and passage date / time as authentication processing It is also possible to just record such as.

  Thereafter, it is determined whether or not the accounting process is completed (step S18), and the accounting process in step S17 is continued until the accounting process is completed. When the accounting process is completed, the control unit 17 outputs an opening control signal to the bar drive control unit 22 to open the gate 20 (step S19). Based on the opening control signal, the bar drive control unit 22 drives the bar 21 in the upward direction, thereby opening the gate 20. Then, the vehicle sensor B14 detects a vehicle immediately after the gate 20, and it is determined whether or not the vehicle has passed the gate 20 based on the output of the vehicle sensor B14 (step S20). When the passage of the vehicle is detected, the control unit 17 outputs a close control signal to the bar drive control unit 22 in order to close the gate 20 (step S21). Based on the closing control signal, the bar drive control unit 22 drives the bar 21 in the lowering direction, thereby closing the gate 20. The process is completed as described above, and the process returns to step S11 and waits until the next vehicle is detected.

  Thus, in the first embodiment, the electronic license plate is used to acquire the ID information of the in-vehicle device and the information of the electronic license plate, and the charging process and the gate opening / closing are controlled based on these information. I have to. Here, after confirming that the corresponding vehicle is located immediately before the gate 20 from the ID information of the in-vehicle device 30 and the vehicle information of the electronic license plate 40, the billing process is executed to open the gate 20.

  Thereby, for example, when there are a plurality of vehicles near the gate 20 and communication is started with the in-vehicle device 30 of the vehicle 52 located slightly away from the gate 20 due to the influence of multipath, etc. Since the vehicle 52 on which the in-vehicle device 30 is mounted and the vehicle 51 that is to be subjected to the billing process just before the gate 20 and to which the electronic license plate 40 is to be read do not match, the billing process is stopped and the billing is performed. It is possible to prevent inconsistency between the billing process and the gate operation, such as the order of the processes changing. And when this vehicle 52 arrives at the position of the vehicle 51 just before the gate 20, it can prevent performing an accounting process redundantly. Therefore, in the charging process and the gate operation, the vehicle information using the electronic license plate can be used to prevent the overlapping of the charging process and to prevent the error of the gate operation, and the vehicle that has completed the charging process can be surely passed. Become.

  Next, as a second embodiment, a second example of the operation in the gate opening / closing system will be described.

It starts and performs transmission / reception with the in-vehicle device 30 in the communication area (step S32). Then, the ID information of the communication partner vehicle-mounted device 30 is read (step S33), and if the charging process for the acquired ID is not completed, the control unit 17 charges the gate passing with the communication partner vehicle-mounted device 30. Processing is performed (step S34).

  Next, it is determined whether or not the accounting process is completed (step S35), and the accounting process in step S34 is continued until the accounting process is completed. When the charging process is completed, the control unit 17 records the ID information of the in-vehicle device 30 for which the charging process has been completed in the memory 16 (step S36).

  Further, as shown in FIG. 6, the control unit 17 of the roadside device main body 11 sends an instruction to the electronic number reading device 25, and the electronic number plate 40 of the vehicle 51 just before the gate 20 is sent by the electronic number reading device 25. Information is read (step S41). Then, the ID information of the in-vehicle device 30 that has completed the billing process recorded in the memory 16 is referred to (step S42), and compared with the acquired vehicle information of the electronic license plate 40, the vehicle information matches the vehicle information. It is determined whether or not there is (step S43). Thereby, it can be confirmed whether the vehicle of the read electronic license plate 40 is the same as the vehicle which completed the accounting process by the vehicle-mounted apparatus 30. FIG. Here, when vehicle information does not correspond, it returns to step S41 and waits until the electronic license plate of the next vehicle is read.

  If there is coincident vehicle information in step S43, the control unit 17 outputs the opening control signal to the bar drive control unit 22 and performs control to open the gate 20 (step S44), and when the passage of the vehicle gate is detected. (Step S45), a control signal is output to the bar drive control unit 22 to close the gate 20 (Step S46).

  As described above, in the second embodiment, the opening / closing of the gate is controlled using the electronic license plate based on the information on the electronic license plate and the completion information of the accounting process. Here, it is confirmed from the vehicle information of the read electronic license plate 40 and the ID information of the in-vehicle device 30 that has been charged that the vehicle immediately before the gate 20 has been charged, and the gate 20 is opened. To.

  Accordingly, when the vehicle 51 that has completed the billing process arrives just before the gate 20 and the electronic license plate 40 is read, the gate 20 can be opened and the vehicle 51 can be passed, so that the authentication process and the gate process are performed. And the like, and the like, and the inconsistency between the billing process and the gate operation can be prevented. Therefore, in the gate operation, the vehicle information based on the electronic license plate can be used to prevent an error in the charging process and the gate operation, and the vehicle that has completed the charging process can be surely passed.
