摘要
基于虚拟仪器对单摆法测量重力加速度实验进行改进,通过H2010型光电门收集摆球的运动信息,利用声卡和LabVIEW搭建数据处理平台采集和处理实验数据.实验结果表明:重力加速度的测量相对偏差为0.7%.
Based on virtual instrument, the gravity acceleration measurement method by simple pendulum was improved. The motion information of the moving ball was obtained by H2010 photoelectric sensors, the data were collected and processed by sound card and LabVIEW platform. The relative error of the measurement results was 0.7 %.
