摘　　要：智能小车稳定快速循迹一直是学者们研究的热门话题,能在直径0.8 mm左右的铁丝形成的轨迹上稳定快速循迹已成为研究的难点。选用STM32高速单片机作为控制核心,选用LDC1314结合四组电感线圈形成四路金属检测循迹传感器,根据传感器返回数据参数的不同即可识别区分金属丝与硬币,从而实现循迹与报警两种不同的任务。给出了快速循迹的算法思路。实验结果表明,设计的智能小车可以稳定快速循迹,在遇到硬币后能发出声光报警信号,并且小车能实时显示行驶速度、里程与时间。Smart car tracking steadily and fast has been a hot topic in scholars research, and smart car tracking the track formed by 0.8 mm di- ameter wire steadily and fast has become the difficulty of research. This paper selects the STM32 high speed single chip microcomputer as con- trol core, and chooses LDC1314 metal detection combined with four groups of inductance coils to form four-line tracking sensor. According dif- ferent data parameters returned by sensors, it identifies the difference between a wire and a coin, so as to realize the tracking and alarming. A fast tracking algorithm is proposed. The experimental resuhs show that the smart car can steadily and fast track, and when it encounters coins, it can send out sound and light alarm signal, and display real-time speed, distance and time.
