XML及STEP标准在流程工业信息集成中的应用研究

Application Research of XML and STEP Standard for Information Integration in Process Industry

流程工业中数据结构复杂,数据之间关系多种多样,如何对这些数据实现标准化处理是一件很困难的事。以前人们采用的方法多为各种零散的方法,或者是借助于制造行业发展起来的STEP来实现,但是STEP主要是用在表述结构化数据的,而对于非结构化数据以及半结构化数据的描述存在很大困难。因此,文中提出用XML来表述流程工业的非结构化数据和半结构化数据,采用XML与STEP标准结合的方式,实现对流程工业数据的集中处理,以便让那些建立在其上的其他信息处理过程中应用。文末给出了XML与STEP相结合所描述的一个典型过程工业信息集成应用案例。

In the process industry, the structure of data is complex and the links between different data are multiple. So it is very difficult to standardize these data. In the past, many methods have been used to solve this problem, such as using the STEP that is used in the manufacture industry. But since the STEP is fit for structure data, this method has much difficulty in expressing the non-structure data. This paper uses the XML to express the non-structure data and the half-structure data of the process industry. Using the XML integrating the STEP can solve the problems happening in the integration of process industry data. The other process of information processing can use the information based on XML and STEP. In the end, this paper gives an example of using XML and STEP to express a synthesis process in the information integration of process industry.
