摘　　要：设计了一个自动往返和智能控制的小车。采用MSP430F149为核心芯片,选用双全桥驱动芯片作为小车电机驱动,利用PWM技术动态控制电动机的转速,红外线光电传感器检测标识线,U型红外光电传感器测量路程。MCU判断和处理各种传感器传回的信息,向电机驱动器发出指令,控制小车在往返过程中实现自动加速、限速、减速、刹车、倒车和在液晶显示器上显示行驶时间,行驶路程等相关数据。Designed an automatic and intelligent control of the car back and forth. The MSP430F149 as the core chip, using both bridge driver chip as the car motor driven, dynamic control of motor speed using the PWM technology, infrared photoelectric sensor detection line, u-shaped electrcal sensor measuring distance. MCU to judge and deal with all kinds of sensors information, issue instructions to motor drives, control the car during the process of back and forth to realize automatic acceleration, speed, deceleration, braking, reverse and displayed on the LCD display drive, travel and other related data.
