摘　　要：以STM32单片机系统为核心控制芯片,对智能小车的车速进行实时监控,并控制其显示在OLED液晶显示屏,采用CCD线性传感器采样,返回单片机进行分析处理,控制小车循迹。通过此次设计,能够在智能寻迹小车的TSL1401线性传感器上提高光感,以适应范围更广的光度。使用了STM32控制系统,提供一种中线差值采样的寻迹方法,选用MG995电动机进行驱动,使智能小车转向更加灵敏。该次优化包含光电测速显示模块,运行效率较高。The STM32 single-chip microcomputer system is used as the core control chip to monitor the speed of the smart car in real time and control it to be displayed on the OLED liquid crystal display. The CCD linear sensor is used to sample and return to the single-chip microcomputer for analysis and processing to control the tracking of the car. Through this design, the light perception can be improved on the TSL1401 linear sensor of the smart tracking car, and it can be adapted to a wider range of luminosity. The STM32 control system is used to provide a tracing method of midline difference sampling. The MG995 motor is selected for driving, which makes the smart car more sensitive to steering. This optimization includes a photoelectric speed measurement display module, which has a higher operating efficiency.
