|
摘要
将红外反射传感器应用于三线摆周期测量装置,通过红外反射传感器将三线摆下盘的扭摆转换成电压信号的变化,利用数据采集系统采集并在电脑上实时显示与存储.改进后的实验装置相对误差仅有0.19%,准确度更高,调节简便、可靠性高.
A three-wire pendulum period measuring device based on infrared reflection sensor was proposed.The torsion of the three-wire pendulum was converted to the change of voltage signal by the infrared reflection sensor.The data was collected by data acquisition system and displayed and stored on the computer in real time.The improved experimental device had some advantages over the existing photoelectric measuring device,such as higher accuracy,easier adjustment and higher reliability.The relative error of the developed experimental device was only 0.19%.
