【正文】 聲波傳感器，習(xí)慣上稱為超聲波換能器或超聲波探頭。此倒車防撞報(bào)警系統(tǒng)主要是利用超聲波的特點(diǎn)和優(yōu)勢，將超聲波測距的原理和AT89C51單片機(jī)結(jié)合于一體，設(shè)計(jì)出一種基于單片機(jī)的倒車防撞報(bào)警系統(tǒng)。超聲傳感器所加脈沖電壓對測量范圍和精度的影響 系統(tǒng)誤差分析及改進(jìn) CX20106芯片介紹時鐘電路 系統(tǒng)顯示電路設(shè)計(jì) 測量盲區(qū)第4章 傳感器指向角超聲波傳感器的應(yīng)用第3章 論文主要內(nèi)容和章節(jié)安排最后，通過對系統(tǒng)的誤差分析，給出了系統(tǒng)的改進(jìn)方案。對于系統(tǒng)的一些主要參數(shù)進(jìn)行了討論，并且在介紹超聲波測距系統(tǒng)功能的基礎(chǔ)上，提出了系統(tǒng)的總體構(gòu)成。交通擁擠狀況也日趨嚴(yán)重，撞車事件屢屢發(fā)生，造成了不可避免的人身傷亡和經(jīng)濟(jì)損失，針對這種情況，設(shè)計(jì)一種響應(yīng)快，可靠性高且較為經(jīng)濟(jì)的汽車防撞預(yù)警系統(tǒng)勢在必行，超聲波測距法是最常見的一種距離測距方法，本文介紹的就是利用超聲波測距法設(shè)計(jì)的一種倒車防撞報(bào)警系統(tǒng)。論文的內(nèi)容是基于AT89C51單片機(jī)倒車防撞系統(tǒng)的設(shè)計(jì)，主要是利用超聲波的特點(diǎn)和優(yōu)勢，將超聲波測距系統(tǒng)和AT89C51單片機(jī)結(jié)合于一體，設(shè)計(jì)出一種基于AT89C51單片機(jī)的倒車防撞報(bào)警系統(tǒng)。通過多種發(fā)射接收電路設(shè)計(jì)方案比較，得出了最佳設(shè)計(jì)方案，并對系統(tǒng)各個設(shè)計(jì)單元的原理進(jìn)行了介紹。AbstractIs day by day prosperous along with the social economy development transportation shipping industry, the automobile quantity climbs in the first mate. Traffic congestion condition also day by day serious, the collision event occurred repeatedly, has caused the inevitable person casualties and the economic loss, in view of this kind of situation, designed one kind to respond quickly, the reliability was high also a more economical automobile guards against hits the early warning system imperative, the ultrasonic wave range finding was the most mon one distance range finder method, this article introduces is guards against using the ultrasonic wave range finding design one kind of backdraft hits the alarm system.The paper is based on the contents of the AT89C51 monolithic integrated circuit reverse collision avoidance system design, mainly using ultrasound features and advantages, ultrasound ranging system and the integration with the integration AT89C51 monolithic integrated circuit, AT89C51 monolithic integrated circuit based on the design of a reverse collision avoidance warning systems. The system used software and hardware integrated approach of a modular and multiuse characteristics.The paper outlines the development and the basic principles of ultrasound tests on the principles and characteristics of ultrasound sensors. Some of the main parameters for the system were discussed, and introducing ultrasonic ranging system functions basis, the overall position of the system. Through multiple launch reception circuit design parison, the best designed program me drawn, and various system design modules principles introduced. On the position of the system circuit chip introduced and elaborated the principles of their work. Papers introduced system software architecture, through programming to achieve system function. Finally, through the analysis of system error, giving the system improvement program me. 目錄第1章 本設(shè)計(jì)時間安排第2章 單片機(jī)超聲波測距系統(tǒng)構(gòu)想 測距儀的工作頻率 單片機(jī)倒車防撞報(bào)警系統(tǒng)各組成單元方案設(shè)計(jì) 系統(tǒng)報(bào)警電路設(shè)計(jì)穩(wěn)壓電源第5章 探頭UCM介紹誤差產(chǎn)生原因分析 針對誤差產(chǎn)生原因的系統(tǒng)改進(jìn)方案第7章 結(jié)束語第8章 致謝第9章 參考文獻(xiàn)第一章
