轧机在线监测系统数据存储模块的设计

The design of data storage module for on-line monitoring system of mill

以LabVIEW作为系统软件的开发平台,结合轧钢机监测信号的特征,设计出一种触发采集的数据采集方式,既能够保证轧制信息的完整性,又可以显著减少数据存储空间;采用一种利用ADO(ActiveX Data Objects,即ActiveX数据对象)技术动态建立数据库的方式,设计出数据库的结构,该数据库可以在Access 2000中直接打开,同传统的数据库访问技术相比,ADO可简化编程,使数据库的存取更灵活。

A kind of triggered acquisition of the ways of data acquisition was designed with LabVIEW as the basis of software development and considering the features of the Monitoring signal of the rolling mill.Such design ensures the integrity of the rolling information and significantly reduces data storage space.Using ADO（ActiveX Data Objects） technology,a way of dynamic establishment of a database was adopted and a database structure was designed,The database can be opened directly in Access 2000.Compared to traditional database access technology,ADO simplifies programming and is more flexible in database access.
