A self-tracking smart car has been designed based on infrared photoelectric sensor and speech recognition technology. The car adopts 16 bit singlechip SPCE061A of Sunplus Inc to work as the core processor of the control circuit, and obtains the path information by the reflected infrared photoelectric sensor. The car can adjust the direction and speed by the location of the black part of the path information to implement self-tracking. Compiled speech program API function to achieve speech capability of human-machine intercourse based on SPCE061 A. Experiments indicates that the smart car can achieve the anticipated steady and credible purpose. The technic can use the fields such as physical disabilities smart wheelchair, service robot, intelligent toy, unmanned driving vehicles, storage, etc.%基于光电传感器和语音识别技术完成了一种自循迹智能小车的设计.该小车采用凌阳16位单片机SPCE061A作为系统控制处理器,以反射式红外光电传感器获取路径信息.根据路径信息中黑线的位置来调整小车的运动方向与速度,从而实现自循迹功能.结合SPCE061A片内资源,编写了语音处理API函数,实现语音人机交互的智能化导航控制.实验表明:智能小车功能达到要求,运行可靠稳定.该技术可以应用于残障人智能轮椅、服务机器人、智能玩具、无人驾驶机动车、仓库等领域.
