[0062] Example two
[0063] Figure 2a This is a schematic structural diagram of an ETC toll entry device provided in the second embodiment of the present invention. The technical solution of this embodiment is further refined on the basis of the first embodiment. The ETC toll entry device 10 further includes:
[0064] The power supply module 140 is used to supply power to the Ethernet communication module 110, the LTE-V communication module 120, and the central processing module 130.
[0065] Further, the central processing module 130 includes:
[0066] The vehicle information acquiring unit 131 is configured to acquire vehicle information sent by surrounding vehicles based on the LTE-V protocol through the LTE-V communication module 120, where the vehicle information includes real-time location information of the vehicle and identification information of the vehicle.
[0067] The target vehicle identification unit 132 is used to identify the target vehicle that is heading to the toll gate among the surrounding vehicles according to the change of the real-time position information of the vehicle.
[0068] In a preferred implementation of this embodiment, the vehicle information acquiring unit acquires real-time position information of the vehicle, and determines the relative position of the vehicle to the toll entrance and the trend of the vehicle movement based on the real-time position information, and the distance from the toll entrance reaches a predetermined distance And the vehicle approaching the toll entrance is identified as the target vehicle.
[0069] In another preferred implementation of this embodiment, it is also possible to determine whether the vehicle is the target vehicle based on the distance between the vehicle and the toll entrance. For example, if the distance between the vehicle and the toll entrance is less than the set distance threshold, the vehicle is directly identified as a target vehicle driving to the toll entrance.
[0070] The identification information sending unit 133 is used to send the identification information of the target vehicle and its own site identification information to the ETC back-end server through the Ethernet communication module 110, so that the ETC back-end server will send the identification information of the target vehicle and the site identification information of the charging entrance Corresponding storage.
[0071] Wherein, when the target vehicle identification unit 132 recognizes the target vehicle heading to the toll entrance, the identification information sending unit 133 sends the identification information of the target vehicle and the site identification information of the toll entrance to the ETC background through the Ethernet communication module 110. The server is used to determine the payment information of the target vehicle.
[0072] Further, the target vehicle identification unit 132 is used for:
[0073] Determine the driving direction of the vehicle according to at least two real-time location information corresponding to the identification information of the same vehicle;
[0074] According to the driving direction of the vehicle and the geographic location of the toll entrance, the target vehicle in the surrounding vehicles driving to the toll entrance is identified.
[0075] Among them, the real-time location information includes the geographic location of the vehicle (the latitude and longitude of the vehicle location) and the current moment. By comparing the geographic location in the real-time location information at different moments, the trend of vehicle movement and the direction of the vehicle can be determined. For example, the target vehicle recognition unit obtains two real-time location information of the same vehicle, where the first real-time location information includes a first geographic location and a first current moment, and the second real-time location information includes a second geographic location and a second current moment. , The second current moment is after the first current moment, and the driving direction of the vehicle is determined by comparing the movement of the second geographic location with respect to the first geographic location.
[0076] Typically, in order to achieve a more accurate result of determining the driving direction of the vehicle, the toll portal can select a set number value (for example, 3, 4, or 5, etc.) according to the actual situation to obtain the real-time position of the set number value of the same vehicle Information to determine the direction of the vehicle.
[0077] Preferably, if the driving direction of the vehicle acquired by the target vehicle identification unit 132 is approaching the toll entrance, and the geographic location of the toll entrance (longitude and latitude of the toll entrance) is in the driving direction of the vehicle, it can be determined that the vehicle is driving towards The target vehicle at the toll entrance.
[0078] Further, the central processing module 130 also includes:
[0079] The station identification sending unit 134 is configured to send its own station identification information to the target vehicle in a unicast manner through the LTE-V communication module 120.
[0080] Wherein, the unicast mode is point-to-point communication, and the site identification information of the charging portal may include site name, site number, geographic location information and other identification information used to uniquely identify the charging portal. The site identification sending unit 134 sends its own site identification information to the target vehicle. The advantage of this setting is that when the ETC toll export device of the non-stop toll collection system is configured at the toll exit, the identification information sending unit 133 correspondingly stores the target vehicle from the ETC background server. When the identification information of the toll entry and the site identification information of the toll entry fail, the ETC toll exit device can obtain the relevant information from the local storage device of the target vehicle.
[0081] In the technical solution of this embodiment, the ETC toll entrance device sends the vehicle identification information of the identified target vehicle and the site identification information of the toll entrance to the ETC back-end server, and sends the site identification information of the toll entrance to the target vehicle to solve the ETC toll exit When the device fails to obtain the corresponding stored identification information of the target vehicle and the site identification information of the toll entrance from the ETC back-end server, the charging cannot be completed, and the effect of ensuring that the target vehicle completes the payment through the ETC is realized.
[0082] in Figure 2b Shows a flow chart of information interaction between vehicles and toll entrances. Such as Figure 2b As shown, the information interaction between the vehicle and the toll entrance mainly includes the following steps:
[0083] S1: After the ETC toll entrance device is powered on, the internal power module supplies power to other modules in the device, and the ETC toll entrance device is activated;
[0084] S2: The LTE-V communication module of the ETC toll entrance device is always in the monitoring state to obtain vehicle information within the signal coverage area;
[0085] S3: When the signal coverage of the LTE-V communication module of the ETC toll entrance device overlaps with the coverage of the LTE-V communication module of the vehicle, the ETC toll entrance device will receive the broadcast information of the vehicle;
[0086] S4: The central processing module of the ETC toll entrance device calculates the running trend of the vehicle through the location information of the vehicle, thereby identifying the vehicle that is about to enter the site;
[0087] S5: The ETC toll entrance device controls the Ethernet communication module to push the vehicle information and the identification information of the toll entrance to the ETC background server on the Internet through the central processing module;
[0088] S6: The ETC toll entrance device successively sends the site identification information of the toll entrance to the vehicle that has identified that it is about to enter the toll entrance through the LTE-V communication module and confirms that the vehicle passes through the toll entrance.
[0089] Through the information interaction between the vehicle and the toll gate, the toll gate can communicate with multiple cars at the same time. Only one set of ETC is deployed at the toll station in a single driving direction, which reduces costs and improves the efficiency of vehicles passing through the toll gate.
