基于树莓派的实验数据采集与处理系统——以RC暂态电路为例

Experimental Data Acquisition and Processing System Based on Raspberry Pi--Taking RC Transient Circuit as an Example

在传统实验教学中,部分实验测量数据量大,人工处理过程烦琐。为了提升实验质效,引入自动化数据采集和快速处理理念,以RC暂态电路为例,基于树莓派和A/D转换器搭建实验硬件平台,利用Python开发实验数据传输与处理软件,实现实验数据自动采集、快速处理,自动生成拟合曲线,辅助学生判读实验结果。实际应用表明,数据采集与处理系统丰富了实验教学,培养了学生的自主学习和实践能力,有助于提升大学物理实验的教学质量。

In the traditional experiment teaching,some experiment measurement data is large and manual processing is tedious.In order to improve experimental quality and efficiency,automatic data acquisition and rapid processing concept are introduced.Taking the RC transient circuit as an example,an experimental hardware platform was built based on Raspberry Pie and the A/D converter,and experimental data transmission and processing software was developed with Python to achieve automatic experimental data acquisition and rapid processing,and automatically generate fitting curves,so as to assist students interpret the experimental results.Practical application shows that the platform enriches the experimental teaching,cultivates the students'independent learning and practical ability,and helps improve the teaching quality of college physics experiments.
