[0002] The current electronic toll collection system (ETC) uses a roadside base station to communicate with an on-board electronic tag installed on the vehicle windshield at 5.8GHz. The roadside microwave antenna and on-board electronic tag are based on 5.8G radio frequency identification (RFID) technology and use low-end ASK modulation. The data transmission rate is only 256Kbit / s for downlink and 512Kbit / s for uplink. It is widely used in highway gantry systems for path identification or segmented billing, and highway entrances and exits for toll deduction.

[0043] refer to Figure 1 An embodiment of the present invention provides a dual-mode communication device, including a main control unit 10, a dual-mode communication unit 20, an antenna unit 50, a communication switching unit 30 and a beam switching unit 40.

[0044] The main control unit 10 is communicatively connected to the external control system 200 and performs data exchange with the external control system 200, specifically including: receiving data from the external control system 200 and sending data / signals through the dual-mode communication unit 20 and the antenna unit 50, or, receiving transmission data / signals from an external device through the dual-mode communication unit 20, and transmitting them to the external control system 200 to realize data transmission.

[0045] In one embodiment, the external control system 200 is a lane control system, and the dual-mode communication device is used in the roadside equipment / base station (RSU) for data transmission / interaction with the on-board unit (OBU) installed inside the vehicle. The lane control system can achieve high-speed data transmission while being compatible with the traditional ETC system through the dual-mode communication device, thereby realizing vehicle-road collaborative control with larger data volume interaction, providing users with more available functions and providing a data transmission basis, improving the functional scalability of the ETC system, and greatly improving the user experience.

[0046] Specifically, the dual-mode communication unit 20 includes a first communication module 21 and a second communication module 22, both of which are connected to the main control unit 10 and are switched by the communication switching unit 30. The first communication module 21 is compatible with the existing ETC system and can perform ETC-based transaction processes, such as identity recognition and transaction deductions; the second communication module 22 can simultaneously perform high-speed data transmission with multiple terminals to ensure efficient implementation of the vehicle-road cooperative function.

[0047] In one embodiment, the first communication module 21 adopts ASK modulation and works on one fixed channel; the second communication module 22 adopts FSK modulation and can work on several fixed channels in parallel. In a specific embodiment, the working channels are divided as shown in the following table:

[0048]

[0049]

[0050] Among them, the first communication module 21 adopts ASK modulation and works on 1 fixed channel, which can realize data interaction with traditional OBU; the second communication module 22 adopts FSK modulation and works on 5 fixed channels. It can work in parallel to realize synchronous access of multiple on-board units (OBU) / multiple users and realize data interaction with new vehicle-road collaborative OBU.

[0051] Specifically, the communication switching unit 30 is connected to the main control unit 10 and is used to receive a control signal from the main control unit 10 to control the first communication module 21 and / or the second communication module 22 to transmit and receive data.

[0052] In one embodiment, the communication switching unit 30 includes two RF switches and a combiner. The first communication module 21 and the second communication module 22 are respectively connected to the combiner through corresponding RF switches. The communication switching unit 30 switches the first communication module 21 and / or the second communication module 22 to access the antenna for data transmission and reception through the two RF switches.

[0053] In one embodiment, the RF switch is a single-pole triple-throw RF switch. When working, the first communication module 21 is connected to the combiner through the RF switch, and the shared antenna unit 50 is used for data transmission and reception; or, the second communication module 22 is connected to the combiner through another RF switch, and the shared antenna unit 50 is used for data transmission and reception; or, the first communication module 21 and the second communication module 22 are simultaneously connected to the combiner through their respective RF switches, and the shared antenna unit 50 is used for data transmission and reception.

[0054] Specifically, by controlling the corresponding RF switches at different levels, the first communication module 21 and the second communication module 22 can enter different working state combinations, and the different working state combinations are specifically described as follows:

[0055] (1) The first communication module 21 transmits and is connected to the antenna unit 50 through the RF switch and combiner to work, while the second communication module 22 does not work;

[0056] (2) The first communication module 21 receives and is connected to the antenna unit 50 through the RF switch and combiner to work, while the second communication module 22 does not work;

[0057] (3) The second communication module 22 transmits and is connected to the antenna unit 50 through the RF switch and combiner to work, while the first communication module 21 does not work;

[0058] (4) The second communication module 22 receives and is connected to the antenna unit 50 through the RF switch and combiner to work, while the first communication module 21 does not work;

[0059] (5) The first communication module 21 transmits and receives, and the second communication module 22 transmits and receives, and both are connected to the antenna unit 50 through the RF switch and the combiner, and work simultaneously.

[0060] In this embodiment, the beam switching unit 40 is connected to the main control unit 10 and the antenna unit 50, and is used to receive a control signal from the main control unit 10 and control the antenna unit 50 to generate different beam directions to suit different working scenarios.

[0061] In one embodiment, the antenna unit 50 includes a plurality of antenna groups 51, the antenna groups 51 include a plurality of antenna modules arranged in a row, and also includes a plurality of phase shifting modules 52 connected to the antenna groups 51 in a one-to-one correspondence. Figure 2As shown, in a specific embodiment, the antenna array design of the antenna unit 50 is as follows, six antenna modules in the horizontal direction form an antenna group 51, each antenna group 51 is connected to a phase shift module 52, and during use, the corresponding antenna module is activated according to the actual working scene, and the phase and amplitude value of each phase shift module 52 are adjusted. For example, when the dual-mode communication device is applied to roadside equipment, it can work in the following two working scenes:

[0062] (1) For the gantry free flow scenario, the radiation area of ​​the antenna needs to be approximately 800 meters long and 15 meters wide;

[0063] (2) At the entrance and exit of a toll station, the radiation area of ​​the antenna needs to be approximately 15 meters long and 3.5 meters wide.

[0064] This requires the antenna unit 50 to form two beams with different radiation areas through beam forming. In the gantry free flow scenario, it is necessary to activate a small part of the antenna modules in the antenna unit 50 to achieve beam pointing A. At this time, the designed antenna direction is as follows: Figure 3 and 4 As shown, the main beam deflection angle is -16 degrees, the vertical beam width is 30 degrees, and the horizontal beam width is 23 degrees. The corresponding design phases of the phase shift modules 52 are shown in the following table:

[0065]

[0066]

[0067] At the entrance and exit of the toll station, most of the antenna modules in the antenna unit 50 need to be activated to achieve beam pointing B. At this time, the designed antenna direction is as follows: Figure 5 and 6 As shown, the main beam deflection angle is 20 degrees, the vertical beam width is 13 degrees, and the horizontal beam width is 18 degrees. The corresponding design phases of the phase shift modules 52 are shown in the following table:

[0068] Phase (>0deg is considered as lag) TR1 200deg TR2 120deg TR3 40deg TR4 320deg TR5 240deg TR6 160deg TR7 80deg TR8 0deg

[0069] The above-mentioned dual-mode communication device can realize high-speed data transmission while being compatible with the traditional ETC system, and further realize vehicle-road collaborative control with a larger amount of data interaction, providing users with more available functions and providing a data transmission basis, thereby improving the functional extensibility of the ETC system and greatly improving the user experience. That is, the dual-mode communication device of the present invention can not only adapt to the existing on-board units (OBU), but also be compatible with new vehicle-road collaborative OBUs, which can lay the foundation for the future diversified development of ETC, the entry of ETC into cities, and the construction of smart cities. In addition, it should be clear that the dual-mode communication device of the present invention is not only suitable for roadside ETC equipment (RSU), but also can be applied to other vehicle-mounted ETC equipment (OBU) based on DSRC technology. The working instructions applied to the vehicle-mounted ETC equipment can refer to the above content.

[0070] refer to Figure 7 The embodiment of the present invention further proposes a dual-mode communication method, which is implemented based on the above-mentioned dual-mode communication device and specifically includes steps S10-S40.

[0071] S10. Obtain current working scene information from an external control system through a main control unit.

[0072] In one embodiment, the external control system pre-generates a work scene library, in which different work scenes are pre-set, and unique corresponding preset beam pointing information is pre-associated for different work scenes. The main control unit can directly obtain the corresponding work scene information and preset beam pointing information from the external control system.

[0073] In this embodiment, the work scenario library includes at least the following two work scenarios:

[0074] (1) For the gantry free flow scenario, the radiation area of ​​the antenna needs to be approximately 800 meters long and 15 meters wide;

[0075] (2) At the entrance and exit of a toll station, the radiation area of ​​the antenna needs to be approximately 15 meters long and 3.5 meters wide.

[0076] It should be clear that in other embodiments of the present invention, the work scene types can be set accordingly according to actual needs, and can be increased or decreased.

[0077] S20. According to the current working scene information, the beam switching unit adjusts the beam pointing of the antenna unit to a preset beam pointing matching the current working scene.

[0078] In one embodiment, after obtaining the current working scene information, the unique corresponding preset beam direction is also obtained, and the antenna unit is further adjusted according to the preset beam direction so that the antenna unit can meet the working requirements of the current working scene. For example, if the current working scene is a gantry free flow scene, it is necessary to activate a small part of the antenna modules in the antenna unit to achieve beam direction A. At this time, the designed antenna direction is as follows: Figure 3 and 4 As shown, the main beam deflection angle is -16 degrees, the vertical beam width is 30 degrees, and the horizontal beam width is 23 degrees. The corresponding design phases of each phase shift module are shown in the following table:

[0079] Phase (>0deg is considered as lag) TR1 0deg TR2 0deg TR3 0deg TR4 70 degrees TR5 140deg TR6 0deg TR7 0deg TR8 0deg

[0080] refer to Figure 8 In a specific embodiment, step S20 includes steps S210 and S220:

[0081] S210: Acquire unique corresponding preset beam pointing information from a pre-established working scene library based on the current working scene information.

[0082] S220. Adjust the beam pointing of the antenna unit to a corresponding preset beam pointing based on the preset beam pointing information.

[0083] In one embodiment, a pre-established work scenario library stores information of different work scenarios, and also pre-associates unique corresponding preset beam pointing information for different work scenarios. Based on the current work scene information obtained, the preset beam pointing information can be directly matched, and the phase and amplitude value of the phase shift module of the antenna unit are adjusted based on the preset beam pointing information, so that the antenna unit can meet the working requirements under different work scenarios.

[0084] S30: Obtain data transmission requirements.

[0085] S40. According to data transmission requirements, the communication switching unit controls the first communication module to perform basic data transmission, and / or controls the second communication module to perform extended data transmission.

[0086] In one embodiment, the data transmission demand can be determined based on the current data transmission type, the size of the data packet to be transmitted and the type of the currently communicating on-board unit. If it is only basic data transmission with a small amount of data such as identity recognition, communication fee deduction, etc., data transmission can be carried out through the first communication module; if it is real-time data transmission with a large amount of data such as road condition videos, pictures and sound data, the second communication module can be called for extended data transmission.

[0087] In a specific embodiment, basic data transmission includes at least identity recognition and communication fee deduction; extended data transmission includes at least identity recognition, communication fee deduction and vehicle-road cooperative information broadcast. Therefore, the first communication module adopts ASK modulation and works on 1 fixed channel. While performing basic data transmission, it plays a role of compatibility with traditional on-board units (OBU), ensuring that conventional on-board units can also realize data transmission normally, thereby ensuring the normal operation of the ETC system; while the second communication module adopts FSK modulation and works on 5 fixed channels, it can work in parallel, realize the synchronous access of multiple on-board units (OBU) / multiple users, and realize data interaction with the new vehicle-road cooperative OBU.

[0088] The dual-mode communication method of this solution can achieve high-speed data transmission while being compatible with the traditional ETC system, thereby realizing vehicle-road collaborative control with larger data volume interactions, providing a data transmission basis for users to have more available functions, improving the functional scalability of the ETC system, and greatly improving the user experience.
