2、本文详细介绍了一种基于 MSP430 单片机的超声波脉冲测距预警倒车雷达系统。该 系统以空气中超声波的传播速度为确定条件,利用反射超声波测量待测距离。并且描述 了系统研制的理论基础,超声波传感器等部分的电路设计以及使用了性能优良的单片机 对系统起到了积极的作用。 论文概述了超声波检测的发展及原理,介绍了超声波传感器的原理以及特性,并且 在在此基础上提出了系统的总体构成。针对测距系统发射、接受、检测、多路控制、显 示部分的总体设计方案进行了论证。 关键词关键词: 倒车雷达;MSP430 单片机;超声波测距。 第 3 页 共 4 页 The Design of Car Parking Sensor
3、 Based on MSP430 Chip Abstract With the development of Chinas automobile industry to tell, especially in the past two or three years entered the private car of the era, automotive electronics industry has become a new growth point, automobile electronic products and market a broad high-margin busine
4、ss of much attention, impressions, and anti-theft device is proof. The past two years, reversing radar became the new love of electronic business, many manufacturers have produced anti-theft device involved reversing radar. Parking sensor is called “reverse collision avoidance radar,“ is secure car parking assist device, capable of voice or a more intuitive display of obstacles around the situation told the driver to lift the driver start the vehicle parking and access around, problems arisin
