PAGE 基于51单片机的智能多功能自行车码表 摘要 随着人们生活水平的不断提高，自行车已经不仅仅是运输、代步的工具，其辅助功能也变得越来越重要。因此，人们希望自行车的娱乐、休闲、锻炼的功能越来越多，能带来大家更多的健康与快乐。自行车码表作为自行车的一大辅助工具迅速发展起来。它能合理计算出速度及公里数,使运动者运动适量,达到健康运动与代步的最佳效果。码表能尽可能真实地反映骑行状况，便于车手及时调整自己的举动。本论文主要阐述一种基于霍尔元件的自行车的速度里程表的设计。以 AT89C52 单片机为核心，A44E 霍尔传感器测转数，温度芯片（DS18B20）获得温度数据，万年历芯片（DS1302）获得日期数据，并通过LED实时显示。文章详细介绍了自行车的速度里程表的硬件电路和软件设计。硬件部分由AT89C52单片机最小系统模块、设置与启动模块、霍尔脉冲模块、日历模块、温度模块和数码管显示模块组成。软件部分用C语言进行编程，采用模块化设计思想。 关键词 AT89C52单片机；A44E霍尔传感器；温度（DS18B20）；日历（DS1302）；速度；里程。 Abstract: As people living standard rise ceaselessly, is not only the bicycle has been walking transport, the tool of the auxiliary function also becomes more and more important. So, it is hoped that the bicycle entertainment, recreation, exercise more and more of the function, can bring you more health and happiness. Occasionally a bicycle as a bicycle large auxiliary tools rapidly. It can reasonable calculation out speed and traveled, make activists motion is right amount, to health movement and the best results instead of walking. Now as far as possible can reflect the riding condition, it is easy to adjust their behavior drivers. This thesis mainly elaborated one based on the speed of the hall element bike the design of the odometer. By AT89C52 single chip microcomputer as the core, A44E hall sensors RPM, temperature chip (DS18B20) get temperature data, calendar chip (DS1302) get date data, and through the LED display. This paper introduces in detail the speed of the bicycle odometer hardware circuit and software design. By AT89C52 single chip microcomputer hardware part minimum system module, set up and start module, hall pulse module, calendar module, temperature module and digital pipe display module. Software of C language program, modular design thought. Keywords AT89C52 single chip microcomputer; A44E hall sensors; Temperature (DS18B20); The calendar (DS1302); Speed; Mileage. 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc326175134 基于51单片机的智能多功能自行车码表 PAGEREF _Toc326175134 \h 1 HYPERLI
