黄河科技学院毕业设计说明书 第 PAGE \* MERGEFORMAT III页 汽车智能测距防撞系统设计 摘 要 汽车智能防撞系统具有有效地提高汽车驾乘人员的安全性、显著地减轻驾驶者的工作负担，使驾车既安全又不易疲劳等诸多优点而受到越来越广泛的重视。本次设计设计了一种以单片机AT89C51和CX20106为核心低成本、微型化，并有数字显示和报警功能的汽车智能测距防撞系统。 首先，本文概述了超声波和超声波传感器的基本原理和特点。 其次，本文分析了系统组成电路的基本工作原理。 最后，本文对系统控制软件进行了设计，给出了控制程序。 在附录中，本文还将给出一些设计的程序和电路图，供参考之用。 关键词：汽车，安全性，测距技术，防撞，超声波 The Design Of Automotive Intelligent?Ranging?collision avoidance system Abstract Authot：zhaolei Tutor：dongxuefeng Automotive radar to improve the safety of vehicle occupants, and significantly reduce the workload of the drivers driving safe and easy fatigue the many advantages of being more and more attention.In this paper Idesign a kind ofAutomotive Intelligent?Ranging?collision avoidance system which is use microcontroller AT89C51 and CX20106 as core.This design not only low?cost and miniaturization,but also can display numbers and have the function of alarm. At first, I will introduce the basic principle and characteristics of ultrasonic and ultrasonic sensors. The second, I will describe the principle of core components in this system. At last, I will talk about the program design. At the supplement, I will write some thing like program and circuit diagram.It be helpful for future design. Key words：Cars, safety, distance measuring technology, anti-collision radar 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc3255312361 绪 论 PAGEREF _Toc325531236 \h 1 HYPERLINK \l _Toc3255312371.1 汽车防撞研究的背景及意义 PAGEREF _Toc325531237 \h 1 HYPERLINK \l _Toc3255312381.2 汽车防撞系统的应用 PAGEREF _Toc325531238 \h 2 HYPERLINK \l _Toc3255312391.3 汽车防撞系统的基本功能 PAGEREF _Toc325531239 \h 2 HYPERLINK \l _Toc3255312401.4 汽车智能测距防撞的发展前景 PAGEREF _Toc325531240 \h 3 HYPERLINK \l _Toc3255312411.4.1 技术支持 PAGEREF _Toc325531241 \h 3 HYPERLINK \l _Toc3255312421.4.2 发展方向 PAGEREF _Toc325531242 \h 3 HYPERLINK \l _Toc3255312432 超声波测距技术 PAGEREF _Toc325531243 \h 5 HYPERLINK \l _Toc3255312442.1 概述 PAGEREF _Toc325531244 \h 5 HYPERLINK \l _Toc3255312452.2 测距传感器的分类 PAGEREF _Toc325531245 \h 5 HYPER
