| 摘 要： | 介绍一种基于MSP430F2274单片机为核心的智能小车。小车采用超声波测距技术实现自动避障，同时通过语音模块来播报出小车与障碍物的距离。为了使测距不受温度影响，用温度传感器实时检测小车周围环境的温度并修正距离计算公式的参数，采用光电编码器来检测小车的速度，运用PID控制算法和PWM来控制小车的精确稳定的运行，从而达到预期的设计目标。

| Abstract: | An intelligent car is described,which is based on the MSP430F2274.The car uses ultrasonic ranging technology to achieve automatic obstacle avoidance,and at the same time through voice module to broadcast the distance between the car and the obstacle.In order to make the distance not effected by temperature,the temperature sensor with real-time detection of the environmental temperature around the car and corrected the distance formula parameters,using photoelectric encoder to test the speed of the car,using PID control algorithm and PWM to control the car’s running accuracy and stability,so as to achieve the expected design goals. |
