The invention provides a vehicle positioning system and method based on radio frequency identification and visible light communication in a tunnel scene. The system comprises an RFID positioning unit, a VLC positioning unit, an information fusion positioning unit, a tunnel light control unit and an information management platform. The initial position information of a vehicle is detected through the RFID positioning unit and the VLC positioning unit, the final position information of the vehicle is calculated by the information fusion positioning unit according to the initial position information of the vehicle detected by the RFID positioning unit and the VLC positioning unit, and the final position information of the vehicle is transmitted to the tunnel light control unit and the information management platform. Corresponding light control and early warning functions are realized; the system has the characteristics of high-precision positioning and low energy consumption, realizes tunnel full-coverage positioning, ensures continuity and stability of positioning information, and greatly improves the intelligent level of tunnel traffic management.
本发明提出一种隧道场景下基于射频识别和可见光通信的车辆定位系统及方法,该系统包括RFID定位单元、VLC定位单元、信息融合定位单元、隧道灯光控制单元和信息管理平台;通过RFID定位单元和VLC定位单元检测车辆的初步位置信息,信息融合定位单元根据RFID定位单元和VLC定位单元检测到的车辆初步位置信息计算车辆的最终位置信息,并将车辆的最终位置信息分别传输给隧道灯光控制单元和信息管理平台,实现相应的灯光控制和预警功能;该系统以高精度定位和低能耗为特点,实现了隧道全覆盖定位,保证了定位信息的连续和稳定,极大提升了隧道交通管理智能化水平。
