摘要
随着自行车行业和电子技术的发展,自行车速度里程计技术也在不断进步和提高,不仅可以显示速度里程,还可以显示热量消耗、心跳等参数,在大家注重环境保护和运动健康的今天,速度里程计不仅可以使运动者运动适量,还可以达到健康运动和代步的最佳效果,因此设计了以单片机为基础的自行车速度里程计,让人们能清楚地知道当前的速度、里程等物理量,而且单片机体积小、可靠性高、价格便宜。
该设计重点阐述了系统的工作原理、硬件构成、各部分的主要功能以及软件的结构和实现。硬件包括主控模块、数据采集模块、数据处理模块、显示模块等组成,采用STC89C52单片机为主要控制芯片,运用自行车车轮上的传感器进行计数,通过一定时间间隔对信号的采集,结合自行车本身车轮参数,送入单片机并由单片机对采集信号进行分析计算,最终在液晶显示器LCD上显示车辆行驶的里程和速度;软件部分用C语言编程,采用模块化设计思想,并在keil和proteus中进行调试和仿真。自行车里程速度计的设计本着安全、方便、性价比高、人性化的原则进行,可使现代生活显著提高。

ABSTRACT
As the bicycle industry and the development of electronic technology, bicycle speed odometer technology is also in constant progress and improve, not only can display speed range, can also display parameters such as heat consumption, heart rate, in everybody pays attention to environmental protection and health/fitness today, speed odometer can not only make people exercise right amount motion, also can to achieve the desired effect of the health sports and walking, thus designed on the basis of the single chip puter bike speed odometer, let people can clearly know the current speed, mileage and other physical quantities, in addition, SCM has small size, high reliability and cheaper price.
The design expounds the working principle, position, main functions of each part and the software structure and implementation. Hardware includes main control module, data acquisition module, data processing module, display module and so on, Using the STC89C52 single-chip puter as main control chip, using sensors on bicycle wheels to count, sending the signals collected by a certain time interval and the bike itself parameters to the single chip pute. Finally Using single chip puter to collect signal analysis and part in C language programming Adopting the idea of modular design, and debugging and simulation in the keil and proteus. Bicycle mileage speedometer design in line
