Embodiment 1
[0036] On the basis of the ETC system, the embodiment of the present invention can seamlessly combine the ETC system and the path identification technology by utilizing the hardware resources of the original ETC system. Expressway traffic and accurate billing.
[0037] This embodiment provides an ETC system with integrated path recognition function, and its structural diagram is as follows figure 1 As shown, including: RSU at the ambiguous path, OBU, RSU at the toll station and the host computer.
[0038] The RSU at the ambiguous path is configured to send a radio frequency signal carrying path information corresponding to the RSU to the OBU on the vehicle when the vehicle enters the communication area of the RSU;
[0039] OBU, used to send the radio frequency signal carrying vehicle information to the RSU at the ambiguous path when the vehicle passes through the communication area of the RSU at the ambiguous path, and the path for sending the RSU at the ambiguous path T...
Embodiment 2
[0061] This embodiment provides a schematic diagram of the service processing flow of the RSU at the ambiguous path, as shown in Figure 4 As shown, the following processing steps are included:
[0062] Step S410, the vehicle equipped with the OBU passes through the communication area of the RSU erected at the ambiguous path.
[0063] Step S420, the RSU at the ambiguous path searches for the OBU on the vehicle, and establishes a communication link with the OBU.
[0064] Step S430, the OBU of the vehicle above sends a radio frequency signal in the 5.80 GHz frequency band carrying vehicle information to the RSU at the above ambiguous path.
[0065] The RSU at the above-mentioned ambiguous path judges whether the OBU installed on the vehicle and the vehicle information in the OBU are legal by reading the vehicle information in the radio frequency signal sent by the OBU. If the judging result of the above legality is illegal, execute step S440; otherwise, execute step S450.
