[0055] Example one
[0056] figure 1 This is a schematic diagram of the structure of an ETC toll entrance device provided in the first embodiment of the present invention. This embodiment can be applied to a situation where a vehicle passes through a toll station and pays through ETC. The device can be integrated and configured at the ETC toll entrance. The ETC toll entrance device 10 includes: an Ethernet communication module 110, an LTE-V communication module 120, and a central processing module 130.
[0057] The Ethernet communication module 110 is used to realize the information interaction between the central processing module 130 and the ETC background server via Ethernet;
[0058] The LTE-V communication module 120 is configured to transmit information based on the LTE-V protocol received from the surrounding environment to the central processing module 130, and to transmit the information received from the central processing module 130 based on the LTE-V protocol. Among them, LTE-V (Long Time Evolution-Vehicle, Long Time Evolution Vehicle) technology can realize vehicle-to-vehicle communication and vehicle-to-road communication. Toll entrance is equipped with LTE-V communication module 120. Based on LTE-V protocol, toll entrance and equipped with vehicle can be realized. LTE-V communication module for communication between vehicles.
[0059] The central processing module 130 is used to exchange information with surrounding vehicles through the LTE-V communication module 120, and send the identification information of the vehicle driving to the toll entrance and its own site identification information to the ETC back-end server through the Ethernet communication module 110 to Make the ETC back-end server correspondingly store the identification information of the target vehicle and the site identification information of the charging entrance.
[0060] Wherein, the identification information of the vehicle is information for uniquely identifying the vehicle. Preferably, the identification information of the vehicle includes: a vehicle identification number (Vehicle Identification Number, VIN) of the vehicle, and/or a license plate number of the vehicle. The site identification information of the charging portal may include identification information used to uniquely identify the charging portal, such as site name, site number, and geographic location information. The ETC background server stores the identification information of the target vehicle and the site identification information of the toll entrance correspondingly, and is used to determine the payment information of the target vehicle when the target vehicle leaves the station.
[0061] The technical solution of this embodiment uses the LTE-V protocol to communicate between the ETC toll entrance device configured at the toll entrance and the vehicle, which solves the problem that the toll entrance in the prior art can only communicate with one vehicle at a time. A toll collection system must be deployed in each lane; when the wireless signal coverage of the toll entrance is large, and when two vehicles pass through the toll station when they are close together, the problem of charging the following vehicle but letting the preceding vehicle pass; When the wireless signal coverage is small, it is required that vehicles can only pass through the station at a very low speed, otherwise the communication problem will not be completed.

Example Embodiment

[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.

Example Embodiment

[0090] Example three
[0091] image 3 It is a schematic diagram of the structure of an ETC toll exit device provided in the third embodiment of the present invention. This embodiment can be applied to a situation where a vehicle passes through a toll station and pays through ETC. The device can be configured at the ETC toll exit. The ETC toll exit device 30 Including: Ethernet communication module 310, LTE-V communication module 320, and central processing module 330.
[0092] The Ethernet communication module 310 is used to implement information interaction between the central processing module 330 and the ETC background server via Ethernet.
[0093] The LTE-V communication module 320 is configured to transmit information based on the LTE-V protocol received from the surrounding environment to the central processing module 330, and to transmit the information received from the central processing module 330 based on the LTE-V protocol.
[0094] The central processing module 330 is used to exchange information with surrounding vehicles through the LTE-V communication module 320 to obtain the site identification information of the toll entrance corresponding to the target vehicle driving to the toll exit; according to the site identification information of the toll entrance and its own site The identification information completes the deduction of the target vehicle, and releases the target vehicle when the target vehicle enters the toll exit.
[0095] Wherein, the site identification information of the toll portal may include site name, site number, geographic location information and other identification information used to uniquely identify the toll portal. Determine the payment information of the target vehicle according to the site identification information of the toll entrance and the site identification information of the toll exit, and then complete the deduction of the target vehicle.
[0096] The technical solution of this embodiment uses the LTE-V protocol to communicate between the ETC toll export device configured at the toll exit and the vehicle, which solves the problem that the toll exit in the prior art can only communicate with one vehicle at a time. A toll collection system must be deployed in each lane; when the wireless signal coverage of the toll exit is large, and when two vehicles pass through the toll station when they are close together, there will be a problem of charging the following vehicle but letting the vehicle ahead; When the wireless signal coverage is small, vehicles are required to only pass through the site at a very low speed, otherwise the communication problem will not be completed. The toll exit can communicate with multiple vehicles at the same time. Only one set of ETC is deployed at the toll station in a single driving direction. Reduce costs and improve the efficiency of vehicles passing through toll gates.
