在物理实验中引入通用数据采集器搭建自组实验平台的研究

STUDY ON BUILDING SELF-PREPARED EXPERIMENT PLATFORM IN PHYSICS EXPERIMENT BY INTRODUCING OF THE UNIVERSAL DATA ACQUISITION

文章以集成霍尔传感器特性研究实验为例,介绍在物理实验教学中引入通用数据采集器搭建自组实验平台的具体应用.实验中所用设备都为传统通用设备,实验现象直接由计算机显示,实验数据导出为Excel文档,利于数据处理、分析.既保留了传统仪器的所有功能,又增加了现代测量手段的自动采集、显示、分析功能.培养学生把多种物理知识交叉使用来解决实际问题.

In this work, we took the study of integrated Hall sensor experiments as an example. We presented the introduction of the universal data acquisition to build self-prepared experiment platform for specific application in physics experiment teaching, whose equipments were all the traditional general-purpose equipments. By used the system, we can obtain that experimental phenomenon can be directly displayed on the computer and large amount of experiment data can be collected and exported as excel format document. The system not only can retain all the functionality of traditional equipments, but also increase the means of mod- ern measurement such as the automatic acquisition, display and analysis functions. This system can also train students to use a variety of physical knowledge to solve practical problems.
