基于51单片机的多功能智能小车的探讨

本次设计一个具备红外循迹、超声波避障及红外遥控智能小车。选择四轮驱动方式,以STC89C52RC芯片为核心控制。采用L298D集成电路驱动直流电机,用单片机产生PWM信号控制电机转速从而调速,通过超声波实现避障,返回距离数据,在此基础上接入红外控制,单片机解码后,自动选择小车功能。本设计结构简单,较容易实现,但具有高度的智能化、人性化,一定程度上体现了智能属性。

An intelligent car with infrared tracking,ultrasonic obstacle avoidance and infrared remote control is designed.Four wheel drive mode is selected,and STC89C52RCchip is used as the core control.L298D integrated circuit is used to drive DC motor,PWM signal is generated by single chip microcomputer to control motor speed so as to adjust speed.Obstacle avoidance and distance data are realized by ultrasonic wave.On this basis,access infrared control.After decoding by single chip microcomputer,the car function is automatically selected.The structure of the design is simple and easy to realize,but it has a high degree of intelligence and humanization,reflecting intelligence to a certain extent.
