基于MSP430控制的智能小车设计

The design of intelligent vehicle based on MSP430 control

利用MSP430单片机作为自动往返小汽车的检测和控制核心,辅以反射式红外传感器、控制电路、显示电路等外围器件,构成了智能小车控制系统,该系统能够完成调速、急刹车、停车、倒车返回等各种运动形式,还可以自动记录、显示一次往返时间和行驶距离,并用蜂鸣器提示返回起点。此外通过PID和PWM脉宽调制技术的结合,提高了对小车位置的控制精度,并且实现了恒速控制。

The system uses the MSP430 microcontroller as the core of detection and control auto-matic round-trip car,and it also include the reflective infrared sensor,control circuit,display circuit and other peripheral devices,the system can complete speed,braking,parking,reversing the return and any other forms of exercise. The system can also automatically record and display a round trip time and distance. The beeper returned to the starting point. In addition,by combining PID and PWM pulse width modulation technology,it improves the control precision of the cart position,and realizes the constant speed controlling.
