下载后可任意编辑简易自行车里程表设计简易自行车里程表设计 朱鸿志 摘要: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纳光电传感器,xxxx 液晶显示器,xxxx,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。 Abstract: 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, xxxx liquid crystal display and xxxx, and achieves the basic purposes of inputting wheel circumference , storing mileage and displaying speed through buttons. 關键词:光电传感器;xxxx 液晶显示器;xxxx 1 设计原理与设计要求 1.1 设计原理 1下载后可任意编辑 本次课设使用 51 单片机完成简易自行车里程表的设计要求,使用对射光电传感器,xxxx 液晶显示器及 51 单片机,实现对自行车速度和里程的实时显示并保存里程。且增加按键设置,通过按键自行输入自行车的车轮周长,并通过按键调取。LED 灯每检测到一次信号脉冲,闪耀一次。 本次设计主要有两部分,分别是硬件部分以及软件部分。硬件部分根据课程设计要求,选择上述硬件模块,即对射光电传感器,普中 51 单片机以及 xxxx液晶显示器,并在接下来的硬件模...
