摘要
基于信息社会日益智能化的发展方向,设计了具有自动控制、精确定位和探测功能的智能小车。该系统以小车模型为载体,以低功耗单片机MSP430F449为核心,实现自动控制功能,利用反应式步进电机实现探测系统的前进、后退、加速、减速与转向,达到精确定位的目的,再加上霍尔传感器、超声波传感器、光敏二极管、接近开关之间的相互配合,实现了小车的智能化探测,完成了距离与速度检测、避障、寻光入库、金属物体检测的功能。
The smart car was designed with automatic control, precise positioning and detection capabilities. With the car model as a carrier, the low-power consumption MCU MSP430F449 as the core, this system can realize automatic control functions, using stepper motor to implement forward, backward, speed up, slow down and turn to perform the purpose of precise positioning, then plus the Hall sensor, ultrasonic sensors, photodiodes, close interaction between switches, to achieve the car＇s intelligent detection, complete the distance and speed detection, obstacle avoidance, seeking light storage and metal object detection functions.
