可视化图形编程在新工科实验教学中的应用

Application of Visual Graphical Programming in the Teaching of New Engineering Experiments

在新工科人才培养的新要求下,工程实践教学改革的目标是培养更多卓越的工程创新型人才。实践设计是新型人才创新实践能力培养的重要载体,为解决课堂知识侧重基本理论与创新思维人才培养之间的矛盾。四川大学电路实验室将基于LABVIEW可视化图形编程软件开发的具有信号分析、数据采集、数据处理、数据保存、数据图形化显示等功能的实验教学系统应用在本科电路实验教学当中。通过固纬GDS-1000B、AFG-2225、科睿源KA3010P硬件平台以及LABVIEW软件,对串联谐振以及单管放大电路的电压、频率以及波形数据进行采集和处理,实现了谐振频率的自主分析和波形数据的有效存储。实验结果表明该系统性能稳定,具有较高的测量精度,并且可以应用到其他实验以及科研项目当中,具有较好的移植性。

Under the new requirements of cultivating talents in new engineering disciplines,the objective of the reform of engineering practice teaching is to cultivate more outstanding engineering innovative talents.In order to solve the contradiction between classroom knowledge focusing on basic theory and the cultivation of innovative thinking talents,Sichuan University Circuit Laboratory has applied the experimental teaching system based on LABVIEW visual graphical programming software,which has the functions of signal analysis,data acquisition,data processing,data saving and data graphical display,etc.to the experimental teaching of undergraduate circuits.The GDS-1000B,AFG-2225 hardware platform and LABVIEW software are used to collect and process voltage,frequency and waveform data from series resonant and single-tube amplification circuits,enabling independent analysis of resonant frequencies and effective storage of waveform data.The experimental results show that the system is stable,has high measurement accuracy,and can be applied to other experiments and research projects with good portability.
