农产品安全生产管理的图形组态软件多源异构数据处理

Multi-source heterogeneous data processing with graphics configuration software for safe production management of agricultural products

面向农产品安全生产管理的图形组态软件能够实现对各类农产品生产信息的有效管理,而异构数据源与图形画面间的数据交换是该图形组态软件研究中亟需解决的关键问题。该文通过分析农产品安全生产管理信息的特点,对其进行特征抽象,构建了一种基于XML(Extensible Markup Language,即可扩展标记语言)的农产品安全生产管理信息描述语言。组态图形画面与受该描述语言约束的XML文档进行数据交换,而不直接与各类异构的数据源交互,从而屏蔽了数据源的异构性。该方法为面向农产品安全生产管理的图形组态软件中的多源异构数据问题提供了一种有效解决方案。

Graphics configuration software for safe production management of agricultural products can effectively manage the production information of agricultural products.The issues of data exchange between multi-sources heterogeneous data and graphics were desired to be a key problem of graphics configuration software.The characteristics of information for safe production management of agricultural products was analyzed and abstracted,and then a XML-based description language was constructed.Configuration graphic interface exchanged data with XML documents that were regulated by this description language,but not directly with heterogeneous data sources.Thus,the differences of heterogeneous data sources were screened by applying this description language.The results showed that the method provides an effective solution for the problem of multi-sources heterogeneous data in the graphics configuration software for safe production management of farm product.
