摘要

为加快智能交通网络建设，设计开发高速公路厘米高精度车辆车道定位平台，实现车路云一体化。公路车辆精密定位系统的设计是以STM32F103CBT6、UWB芯片为核心来实现锚点和标签的设计。同时，通过增加射频放大器，修改发射功率，优化软件代码，可以实现实时高精度远距离定位，保证150m通信。最后，QT接口给出了飞行器的运行轨迹。实验结果表明，该系统稳定可靠，定位误差可达到10cm以内，在QT平台上可实现高秒刷新率。

Research on Road Vehicle Positioning Technology based on UWB Communication

In order to accelerate the construction of intelligent transportation network, we will design and develop a high-precision vehicle lane positioning platform for highway centimeters to realize the integration of vehicle and road clouds. The design of the highway vehicle precision positioning system is based on STM32F103CBT6, UWB chip as the core to achieve the design of anchor and tag. At the same time, by adding RF amplifiers, modifying the transmitting power and optimizing the software code, it is possible to achieve high precision long distance positioning in real time and guarantee 150m communication. Finally, the QT interface presents the vehicle's trajectory. Experimental results show that the system is stable and reliable, the positioning error can be achieved within 10cm, and the high refresh rate of the second can be achieved on the QT platform.
