随着人们生活水平的提高,人们对于生活质量的要求也日益增加,尤其是对健身的要求,自行车也不再仅仅是普通的运输、代步工具,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,让人们能清楚地指导当前的速度.随着科技的迅速发展,单片机的应用也越来越广泛,并带动传统控制检测技术不断更新.现在的车速表大多是电子式的,用LED数码管或LCD即时显示,显示更加直观.电子式车速表采用接触车速传感器代替软轴传动,可使车速表的安装位置不受距离限制,进一步有效地克服了机械式车速表中的诸多不足.本论文主要阐述的是一种基于霍尔元件的测速仪的设计.以AT89S51单片机为核心,A44E霍尔传感器测转速数,实现对自行车速度的测量,并能将自行车的速度用LCD实时显示.本文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送入单片机系统,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.

As people's living standards improve, people's requirements for quality of life increasing, especially for the requirements of fitness, cycling is no longer just an ordinary transport, means of transport, but become entertainment, leisure, exercise of choice. Bicycle speedometer to meet basic human needs, so that people can clearly guide the current speed. With the rapid development of science and technology, SCM applications are increasingly being used and promote the traditional control detection technology constantly updated. Most of the current electronic speedometer, and LCD with LED digital tube, or real-time display, display more intuitive. Electronic speedometer instead of using the contact speed sensor shaft drive, can not be installed speedometer distance limitations, and further mechanical effectively overcome the disadvantages of speed tables. Described in this thesis is based on Hall element of the gun design. The AT89S51 microcontroller core, A44E Hall sensor speed measuring the number of measurements to achieve the speed of the bike, and can speed bike with LCD time display. This paper describes a bicycle speedometer of hardware and software design. Hardware components will be a bike by Hall the number of pulses per revolution into the SCM system, SCM system and then send the signal through the processing display. Software components in assembly language programming, modular design. The hardware circuit is simple, routine versatile, fully meet the design requirements.
