基于STM32的交通灯信息感知硬件系统设计与实现

Hardware Design and Implementation of Traffic Light Information Acquisition System Based on STM32

为了解决行驶过程中驾驶员视线受阻而不了解前方交通灯信息的问题,设计了以STM32为主控芯片、集成高精度北斗定位模块和无线通信模块的交通灯信息感知系统;介绍了系统的硬件结构框图以及各器件的选型,完成了硬件原理图的设计以及4层PCB板的绘制;最后对车载终端硬件进行通信性能测试,硬件平台稳定运行,系统功能能够完成。

In order to solve the problem that the driver's line of sight is blocked during the driving process without knowing the information of the traffic lights in front,a traffic light information acquisition system was designed with STM32 as the main control chip and integrated with high-precision Beidou positioning module and wireless communication module.The hardware block diagram of the system and the selection of various components were introduced.The design of hardware schematic diagram and the drawing of 4-layer PCB was completed.Finally,the vehicle terminal hardware was tested for communication performance.The result shows that the hardware platform runs stably and the system functions can be completed.
