DAQmx与OPC在过程控制实验装置中的应用

Application of DAQmx and OPC in process control experiment device

过程控制实验是过程控制工程课的重要教学环节,设计并开发了基于DAQ(Data Acquisition)模块和OPC(OLE for process control)通信技术的过程控制实验装置。采用VB.NET编程,使用DAQmx的方法来驱动USB数据采集模块进行数据采集、控制,通过OPC技术与组态王监控程序进行数据交换,文中详细叙述了开发过程,并给出了程序代码。

Process control experiment is an important teaching link of Process Control Engineering course. Designed and developed based on DAQ（ Data Acquisition） modules and OPC（ OLE for process control） communication technology process control experimental device.With VB.NET programming,the method of using DAQmx powered USB data acquisition card for data acquisition,control. Exchange data through OPC technology and Kingview monitoring program.The article includes the process of its development,and the program line is also given out.
