为开展钢筋混凝土结构实验演示教学，自主研发基于虚拟仪器的实验教学演示系统。采用NI cDAQ搭建混合信号采集系统，以实验演示教学为目标设计信号采集和数据处理软件，实现数据清零、数据修正和数据记录、画图等功能。实践表明，该演示系统为推动立体化启发式实验教学和互动式实验教学奠定了坚实基础。

In order to conduct demonstration teaching of reinforced concrete structure experiment, the research and development of experiment teaching demonstration system based on virtual instrument have been done independently. With NI cDAQ the mixed-signal acquisition system is built, the signal acquisition and data processing software is designed for experiment demonstration teaching. The functions of data clearing, data correction, data recording and drawing are achieved. Practice result shows that the demonstration system can lay a solid foundation for the stereoscopic heuristic experiment teaching and interactive experiment teaching. With the new test technology applied to teaching, the teaching efficiency and quality are increased. The experiment teaching demonstration system has a good application value.
