中文摘要: 为了实现自行车的智能化和娱乐化,以AT89S52单片机和霍尔传感器为核心设计了一种里程表.利用直流电机旋转来模拟车速,通过H桥驱动,将不同转速转变成的不同频率的脉冲信号以外部中断形式输入至单片机,并将所得数据存储到芯片24c02中,采用LCD液晶显示总里程、定时里程、平均速度、瞬时速度、加速度及秒表定时时间.
Abstract:In order to realize the bicycle intelligent and entertainment，speedometer design is based on AT89S52 microcontroller and Holzer sensor An odometer odograph is designed by using the rotation speed to simulate DC motor，which is driven by Hbridge．The pulse signals with different frequency and speed are sent into the SCM in the form of external interruption，and the data received are stored in the 24c02．Then the LCD displays total mileage，time average speed，instantaneous velocity and acceleration，stop watch timing．
