基于AT89S51单片机自行车里程/速度计的设计

Design of Bicycle Mileage / Speed Meter Based on AT89S51

设计并制作了一款以AT89S51单片机为主控制器,使用霍尔传感器进行自行车里程/速度测量的装置。这种装置通过检测霍尔传感器在一定时间内自行车轮胎旋转圈数,再利用软件编程将圈数转换成自行车行驶的里程和速度,最后用数码管显示里程和速度。这种装置具有超速讯响提醒功能,也可以运用于电动自行车、摩托车及汽车等机动车的仪表上。

This paper designs and makes a microcomputer-based controller with AT89S51,using a bike mileage Hall sensor / speed measuring device.First of all,the Hall sensor by detecting a certain period of time the number of bicycle tire rotations,and then circle the number of software programming will be converted into a bike odometer reading and the implementation of speed,and finally with Digital tube display distance and speed.Bicycle mileage / speed meter also has a ring to remind speeding hearing function.Can also be used in electric bicycles、motorcycles and automotive instrumentation on the vehicle.
