摘要
随着私家车的增多,给日常生活带来了方便,同时也给交通带来极大压力。汽车的安全问题变得尤其重要。本文介绍基于LPC2210的汽车防撞系统。此系统采用了两种测距方法:调频连续波雷达测距和超声波测距。提示部分采用了语音播报和LCD显示两种方式。本文阐述了信号的发射接收、语音集成芯片、LCD显示这三部分与核心控制芯片的硬件连接及整个系统的软件流程图。
with the private cars increasing , it has brought convenience, but also to the traffic pressure. Automobile safety is very important. In the paper it introduces the collision avoidance system of vehicle applying LPC2210. This system has used two methods to measure distance, ultrasonic measuring distance and millimeter wave measuring distance. Alarming parts have applied the speech alarm and LCD display. Signal transmission the reception the voice integration chips and LCD display with some of the core chip hardware connection process and software flowchart.
