智能型物理实验计时测量系统研制

Development of intelligent timing device in physics experiment

在科学技术迅速发展的今天,提升实验技术含量是优化物理实验教学的重要途径之一.采用单片机技术,研制的智能型物理实验计时测量系统,可在不改变原实验装置的前提下,用红外光电传感器对测量物体进行检测,实现了自动计时、自动计数功能,同时能将检测信号进行自动处理,算出被测物理量,达到自动、实时测量的目的,有效减小了传统计时仪器的计时误差和数据计算造成的系统误差.

In the rapid development of science and technology today,it is one of the important way of improving the technological content to upgrade the quality of physics experiment teaching.The device uses single-chip AT89S52 control without changing the original experimental equipment.It can make the work of automatic timing and automatic counting by testing the objects with infrared photoelectric sensors.The testing signal also can be processed automatically while the test physical quantity would be measured.Then the objective of automatically and real-time measurement would be achieved.Timing error of the old time-measuring instrument and system error of data count can both be effectively decreased.
