摘要
利用虚拟仪器技术设计了一种过程参数监控系统，介绍了系统的硬件组成，PC机接口电路及系统的软件模块组成，并简要说明如何生成动态链接库DLL，以便在VB应用程序中调用。
In this paper, we design an control system which can measure the process paraments using virtual instrument. Hardware circuit,PC interchange circuit and software modual of system are introduced. At the same time it is also simply introduced how to generate a DLL which can be called in a VB application.
