【2017年整理】基于单片机控制自行车速度里程表的开题报告.doc

安徽工程大学机电学院毕业设计(论文)开题报告 题　　目 单片机论文的研究意义随着居民生活水平的不断提高，自行车不再仅仅是普通的运输、代步的工具，而是成为人们娱乐、休闲、锻炼的首选。自行车里程表能够满足人们最基本的需求，让人们能清楚地知道当前的速度、里程等物理量。主要阐述一种基于霍尔元件的自行车里程表的设计。以 AT89C52 单片机为核心，A44E 霍尔传感器测转数，实现对自行车里程/速度的测量统计，采用 24C02 实现在系统掉电的时候保存里程信息，并能将自行车的里程数及速度用LED实时显示。文章详细介绍了自行车里程表的硬件电路和软件设计。硬件部分利用霍尔元件将自行车每转一圈的脉冲数传入单片机系统，然后单片机系统将信号经过处理送显示。软件部分用汇编语言进行编程，采用模块化设计思想。该系统硬件电路简单，子程序具有通用性，完全符合设计要求。1.2单片机控制自行车速度、里程表的发展现状.3直流稳压电源的发展趋势 三、研究方案及工作计划（含工作重点与难点及拟采用的途径） 3.1研究方案 图1 系统控制示意图第一周：对毕业设计题目进行选题；第周第周第周第周第周第周撰写毕业设计第周第周第周第周第周毕业设计第周完成设计电子版初稿第周毕业设计修订第周毕业设计（打印版），第周提交毕业设计（打印版），毕业答辩Krassimir T，Atanassov，Nikolai G.etal.Remark on Two Operations Over Intuitionistic Fuzzy Sets[J].

A system such as an electronic clock which employs counters has its storage and processing capabilities spread throughout the system because each counter is able to store and process numbers. Present day microprocessor based systems depart from this conventional approach by separating the three functions of processing, storage, and transmission into different section of the system. This partitioning into three main functions was devised by Von Neumann during the 1940s, and was not conceived especially for microcomputers. Almost every computer ever made has been designed with this structure, and despit
