摘要
为提高单摆实验的测量精度及自动化程度,采用AT89S52单片机构成智能控制系统,利用光电检测实现对单摆周期进行测量,实现周期与重力加速度自动计算与显示,达到自动与实时测量目的。其测量法年夫优于传统的手工方法:该装置是一种低成本,高精度的单摆实验装置。
On the basis of the traditional instrument of a simple pendulum, an intelligent device to measure gravity acceleration was developed. By this device with an intelligent system composed of AT89S52 single chip microcomputers, the period of a simple pendulum and the gravity acceleration can be measured automatically and displayed clearly.
