传感器原理虚拟实验预习教学系统的开发

Development of Virtual Experiment Preview Teaching System of Sensor Principle

用Visual Basic 6.0系统开发了传感器原理虚拟实验预习教学系统.该系统采用图形用户界面、下拉菜单和对话框驱动,通过下拉菜单进行实验步骤的操作、参数设置等,通过对话窗口选择实验项目、查看实验原理、电路结构,在窗口实时显示采集数据、描绘曲线、计算非线性误差.虚拟仿真实验将真实实验用图形显示出来,有利于学生对传感器的原理和特性的理解和掌握,激发了学生的学习积极性,提高了实验教学效果.

A Virtual experiment system of sensor principle was developed based on Visual Basic 6. 0. The system was driven by Graphical User Interface,drop-down menu and dialog box. The operations of experimental procedure,parameter setting and so on were selected and input in dialogue windows. The processes of collecting data,drawing curve,calculating nonlinear error were displayed in windows simultaneously. Virtual experiment was expressed by graphics visually using virtual experiment,which is benefit for student to understand and master the principles and characteristics of sensors. The system can stimulate learning enthusiasm of the students and improve the experimental teaching effect.
