自行车测速器论文
摘 要
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。
本次设计给出了以AT89S51为核心，利用单片机的运算和控制功能，并采用系统化LCD显示模块实时显示所测速度的设计方案以及系统软件。
该方案由于使用了LCD显示模块，以及高效快速算法，因而可在节约系统资源和简化程序设计的基础上保证测量精度和系统实时性 。速度显示部分采用LCD显示, 因而节省了所需单片机的口线和外围器件, 同时也简化了显示部分的软件编程。案实现了电动车速度即时显示。

Along with the quick development of science and technology, the application of SCM and more extensive, drive traditional control test technology constantly updated. Now the speed table is mostly electronic, use LED digital tube or LCD instantly shows, show more intuitive. Electronic speed table by using the contact speed sensor instead of soft shaft transmission speed table, can make the installation position of not affected by distance limit, further effectively overcome the speed to the table of mechanical some shortcomings.

This design is given based on AT89S51 as the core, of the microcontroller calculation and control function, and by using the systematic LCD display module real-time display measured the speed of design program and system software.

The scheme by using LCD display module, and quick and efficient algorithm, thus in saving system resources and simplify programming based on guarantee measuring precision and real-time system. Speed shows part adopts LCD display, thereby saving the required microcontroller mouth lines and peripheral equipments, simultaneously also simplifies shows part of the software programming. Case realized the electric car speed instantly shows.
