Abstract: The state modeling theory is an effective approach of analyzing the dynamic behavior of the objects, the state diagram visually depicts the transferences between multiple states. CDT On-Line system is the basic component of CPCIMS which is used for collecting data deriving from equipments ,posts and barcodes. The paper models the CDT On-Line system using the state modeling approach based on the analysis of its infrastructure , in order to offer an exact requirement analysis and to assist the software design and the code production for CDT On-Line system.

摘要： 状态建模理论是分析对象动态行为的有效方法，状态图可以直观地反映对象的状态迁移。CDT On-Line系统是用于实时采集彩管生产线质量信息的管理信息系统。文章运用状态建模的方法对CDT On-Line系统中的自动化生产过程进行了建模，目的是保证数据采集的可靠性和有效性，建模结果得到了实践的证明。
