使用传感器进行物理实验数据的采集,是中学物理教学发展的方向,笔者介绍一种低成本的基于 USB 声卡和 LAB-VIEW 软件平台的数据采集系统,在满足中学物理的质性和量性实验的前提下,为现实不少没有配置商用传感器数据采集系统的广大学校开展传感器方面的教学,打开思路,实现实验数据采集的一种切实可行的方法.利用传感器做实验,采集实验数据,最大的好处可以节省记录数据,手工方式处理数据所用的时间,从而可以把更多的时间用以对物理过程和规律的探究.其次,利用传感器做实验可以把可见度小、瞬时变化的物理现象和过程进行准确无误
The use of sensors for the acquisition of physical experiment data is the direction of the development of physics teaching in secondary schools. The author introduces a low-cost data acquisition system based on USB sound card and LAB-VIEW software platform. In order to meet the qualitative and quantitative experiments of middle school physics Under the premise, for the reality that many schools do not have a commercial sensor data acquisition system to carry out the teaching of sensors, open ideas, experimental data collection to achieve a viable method.Using the sensor experiment, collecting experimental data, the greatest benefits Can save the data recorded, the time spent by manual processing of the data, so that more time can be used to explore the physical processes and laws.Secondly, the use of sensors to experiment can be visible and transient physical phenomena and processes to accurately Wrong
