摘 要
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。自行车测速仪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、时间、温度等物理量。本论文主要阐述一种基于霍尔元件的自行车测速仪的设计。
以AT89S52单片机为核心，霍尔传感器测转数，实现对自行车里程、速度、时间、温度的测量统计，采用24FC512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及速度用LCD实时显示。文章详细介绍了自行车测速仪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LCD显示。软件部分用C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。
为了便于扩展和更改，软件的设计采用模块化结构，使程序设计的逻辑关系更加简洁明了。使硬件在软件的控制下协调运作。正文中首先简单描述系统硬件工作原理，且附以系统硬件设计框图，并介绍了单片机微处理器的发展史，论述了本次毕业设计所应用的各硬件接口技术和各个接口模块的功能及工作过程, 并具体描述了AT89S52接口的软、硬件调试。其次阐述了程序的流程和实现过程。仿真实验表明所设计的硬件电路及软件程序是正确的，满足设计要求。

Circuit Design of Bicycle Velocimeter Based on MCU
Abstract
With the developing of people’s life, the bicycle is not only the universal tool of transportation and substitute for walking, but becomes the first choice of entertainment and exercising. The bicycle speedometer can fulfill the basic need of people’s life, so that they can learn the speed, the mileage, Time, temperature of the bicycle. In this paper, the bicycle speedometer design based on the Hall element is elaborated.
By AT89S52 as kernel, using Hall element to measure revolution, the measure and statistic are achieved. The range information is saved by 24FC512 when the power is off, the bicycle speed can be displayed on LCD. In this article, the hardware circuit and software design of bicycle speedometer instrument are introduced in detail. About the hardware, the pulse number is transmitted of one cycle of the bicycle into Single Chip Microcomputer system. Then the signal processed by Single Chip Microcomputer system is sent to display scream. About the software, in assemble language; the program is designed in the mode of modules. The system has simple hardware, common sub-program, and meets the demand of design.
For the sake of easy to expand with the design adoption mold a logic for turning construction, making procedure designing relation that change, software more shorter and more easier to understand. Make hardware control in software descended to moderate the operation. The text inside describes the system hardware work principle in brief first, and attach with the system hardware design frame diagram, combine development history that introduced the single a machine microprocessor, discuss this graduate design a function for applied each hardware connecting a people the technique connects with each one a mold piece and work processes, combine to describe in a specific way the AT89S52 electric circuit connects oscular and soft, the hardware adjusts to try. Expatiated the process of the procedure the next in order with realizes process. The simulation results have proved that the hardware circuits design and software program is correct, and the system can meet the designing requirement completely.
