介绍了采用电感感测路径的自动循迹小车控制系统.自动寻迹小车控制系统以STC12C5A 60S2为核心控制 单元,采用 LDC1000电感数字转换器完成道路检测,采用两个步进电机完成小车驱动.道路检测算法,采用基于滑窗滤波算 法的扇形扫描法判断小车的偏移方向.搭建实验平台,小车能够完成自动循迹功能,达到第五届TI杯电子设计大赛要求, 该系统设计可为相关的货运机器人等提供了参考.
This paper introduces the design of automatic vehicle tracking control system based on LDC1000. Road detection module uses TI's LDC1000 digital inductance converter, tracking wire to be detected. Automatic tracking trolley driven by stepping motor, the controller uses STC12C5A 60S2. In the detection process, the road information detected by LDC1000 using sector scan method to determine the travel direction of the trolley, and control the tracking trolley by two stepper motor in motion. By building the experimental platform, the trolley can better complete automatic followed trace function, and provide a reference for related freight robot.
