| 摘 要： | OPC历史数据存取规范基于COM,要将其移植到.NET平台,需要解决编排过程中数据类型转换、接口实现、参数传递等问题。研究C#接口属性类、.NET托管和非托管的转换后,解决了OPC历史数据存取规范1.2定制接口COM编排的问题。利用研究成果,能将工业过程自动化系统中产生的历史数据抽取出来,形成数据仓库。

| Abstract: | OPC historical data access specification is based on COM, the problem such as the data type transform, interface implemen-tation, argument pass must be handled when it migrate to.NET platform.The problem of COM marshalling OPC historical data access specification version 1.2 is solved after the C# attributes class of interface and the transform of.NET managed and unmanaged have been studied.The data warehouse can be constructed by extracting the historical data from the industrial process automation system followed the paper. |
