基于单片机超声波避障智能寻迹运物小车系统设计

摘要

本文介绍了以盛群HT46R232 MCU为主控芯片，利用红外传感技术、超声波测距技术、步进电机控制技术设计了超声波避障智能寻迹运物小车系统。设计的小车可以沿规定的线路自动寻迹前进并利用超声波避障。当到达指定地点时，利用压力传感器与步进电机卸载小车上的货物。该小车系统具有一定的智能性，经过改进后可应用于科学勘探等用途。%This paper presents the design of ultrasonic obstacle avoidance intelligent path following mini-car system based on HT46R232 MCU, using infrared sensor technology, ultrasonic distance measurement technology and step motor control technology. The mini-car can forward automatically by trace the path and avoid obstacle by ultrasonic. When arriving the place, the mini-car can unloading by pressure senor and step motor. The mini-car system is intelligent, can be used to scientific exploration and so on.
