摘　　要：介绍利用反射式红外光电传感器实现小车自动寻迹导航的设计与实现以及小车的一种寻迹算法。自动寻迹是智能小车(Smart Car)机器人系统的重要组成部分,其用实现小车自动识别路径。在实验中采用与白色地面色相差很大的黑色线条引导小车按照既定路线前进,系统控制核心采用飞思卡尔的MC9S12DG128B单片机,系统驱动采用控制方式为PWM的直流电机。实验证明此方案可行并且可靠。该技术可以应用于无人驾驶机动车、无人生产线、仓库、服务机器人等领域。This article introduces the design and execution of automatic track finding navigation car realized by reflective infrared photoeletric sensor and its algorithm. The automatic trak tiding is an important function of smart - car robot system, to realize car automatic identification path. In the experiment, taking use of the black guiding wire whose color distinguishes from the white background to guide the car to move along the given line automatically. The Mcgs12DG128B from freescale single chip microcomputer is used for the control core in this system,and the PWM direct current electromotor for the motive force or power system. The experiment proves that this project is feasible and credible. This technology could serve to driverless mobile, unmanned producing lines, warehouse, service robot and etc.
