简易自行车里程表设计

Simple Bicycle Odometer Design

随着现代社会对绿色出行的提倡及全民养生健身意识的觉醒,自行车逐渐成为我们生活中首选的中短途代步工具。对于那些喜爱骑行健身的人来说,自行车车载速度里程表显得尤为重要。而老式的传统里程表由于是机械构造,长期使用磨损严重,容易造成极大的误差。因此,电子里程表便应运而生,成了自行车最好的车载伴侣。在这样一个大背景下,本次课设我设计的电子里程表采用光电传感器,LCD1602液晶显示器,AT89C51,通过按键达成输入车轮周长,存储里程,显示速率等基本用途。

With the promotion of green travel in modern society and the awakening of the consciousness of national health and fitness,bicycles have gradually become the preferred medium and short-distance transportation tools in our lives.For those who like to ride fitness,bicycle speedometer is particularly important.The old-fashioned traditional odometer belongs to mechanical structure and has been worn for a long time,so it is easy to cause great errors.Therefore,the electronic odometer came into being and became the best companion for bicycles.Under such a large background,the electronic odometer the author designed uses photoelectric sensors,LCD1602 liquid crystal display and AT89C51,and achieves the basic purposes of inputting wheel circumference,storing mileage and displaying speed through buttons.
