一种自动往返小车的设计与制作

Design and Realization of Intelligent MiniCar

介绍自动往返小车的一种设计方法,给出了控制系统的硬件和软件设计。本设计以单片机为核心,以光电检测获得外部信号,采用PWM对小车的制动进行控制,以LED对行程和所用的时间进行显示。此设计电路成熟、工作稳定、容易实现控制。

This paper introduces the designing method of an intelligent minicar and gives the hardware and software design of the controlling system.The single-chip microcomputer is the core of the controlling system.This design uses photoelectric detection to obtain the external signals and uses PWM to control the braking of the car,it uses LED to display the trip and the time.The circuits of this design is mature,stable and easy to implement control.
