摘要

随着社会的发展，人们对健康程度越加关注，常常通过骑自行车来锻炼身体，自行车不但是运动健身的良好方式，而且也是良好的交通工具。在这个追求节能环保的年代，自行车清洁环保，完全符合时代的要求。现如今，越来越多的年轻人选择自行车作为运动锻炼工具，自行车具有环保、节能、灵活、方便等特点，而且价格低廉，一直受到人们的青睐，骑自行车能压缩血管，使得血液循环加速，大脑摄入更多的氧气，再加上吸入大量新鲜空气，会觉得脑筋更清楚。骑在车上，你会感觉十分自由且畅快无比。它不再只是一种代步工具，更是愉悦心灵的方式。在国外，骑自行车健身可以说是方兴未艾。根据《美国新闻与世界报道》披露，美国有2000万人甩骑自行车健身，而且参加的人数越来越多，1987年比1986年增加了30％，1988年又比1987年增加了36％。现如今，选择自行车锻炼的人数逐年呈现攀升趋势，可见，自行车运动永不淘汰。一直以来，在骑自行车的过程中，人们都无法了解自行车运动的速度，自己热量消耗的大小，随着科学技术的发展，人们在自行车的研究上取得了一定的突破。为了掌握自行车的测速及骑车者身体运动情况，可在自行车中安装测速装置，掌握自行车的车速情况，对骑车者的安全具有积极的意义。测速装置不但对自行车的速度进行测试，而且还对运动过程中的各种参数进行测定，全面掌握自行车在运动过程中的情况。本文对以单片机为研究中心，对单片机的自行车测速系统进行研究分析，使自行车的功能得到进一步的提升，满足人们的需要。

Abstract

With the development of society, people become increasingly concerned about the level of health, often by bicycle for exercise, not only a good way to bike sports and fitness, but also a good means of transport. In this pursuit of energy saving era, bike clean environment, full compliance with the requirements of the times. Nowadays, more and more young people choose to bike as exercise tools, bicycles with environmental protection, energy saving, flexible, convenient, and inexpensive, has been favored by people, cyclists can compress blood vessels, so that blood circulation to accelerate, the brain more oxygen intake, coupled with the inhalation of fresh air will find their brains more clearly. Riding in the car, you will feel very free and very fun. It is no longer just a means of transport, but also spiritual joy ways. In other countries, cycling fitness can be said to be in the ascendant. According to "US News And World Report" revealed that the United States has 20 million people ride a bike fitness rejection, and more and more number of participants in 1987 increased by 30% compared with 1986, 1988 and 1987 off than a 36% increase. Now, select the number of yearly exercise bike showing rising trend, visible, cycling never eliminated. All along, the cycling process, people can not understand cycling speed, calories burned their own size, with the development of science and technology, people in the study of the bicycle has made some breakthroughs. In order to grasp the speed and movement of the bicycle rider's body can be installed in the bicycle speed measurement equipment, control vehicle speed bike, with positive implications for the safety of the rider. Speed measuring device not only to test the speed of the bicycle, but also on the movement of the various parameters were measured during exercise bike fully grasp the situation. In this paper, the microcontroller as research centers, bike speed microcontroller systems research and analysis
