Design of Simulation Demonstrative Experiment Based on Wireless Module and Visual Basic

介绍了基于无线模块和Visual Basic仿真演示实验设计的功能.并以牛顿第二定律实验为例,利用霍尔传感器将实验物理变量的变化转换成电脉冲信号并通过无线模块发射.利用USB无线模块接收将信号输入计算机,然后控制Visual Basic设计的演示实验的仿真界面,实现仿真界面与演示实验同步进行.

In order to solve the problems in the didactical traditional demonstrative experiment, this articleintroduces the signal acquisition function of wireless module and the function of designing virtual simulation experiments of Visual Basic. Meanwhile, this article takes the Newton Second Law as an example, firstly, transform the experiments of physical variables to electric pulse signal by means of hall element and through wireless module launch, secondly input these signals via USB wireless module receiver in computer. The Visual Basic will them oa its presupposed experiments and simulative simulative interface to interface. receive these electrical signals and demonstrate realize the synchronization of demonstrative
