摘要
随着计算机在配料中的应用,配料数据库中存储的数据量急剧增大。为了将隐藏于数据库中的重要信息抽取出来用于控制配料接批性能,首先探讨了配料数据库设计方法,详细分析了配料数据表关系和数据表实体属性,讨论了纺纱配料规则的一般性描述,然后根据规则的描述提出一种“窗口扫描”的算法,从该数据库中自动提取配料规则,并给出了应用实例。实例表明,“窗口扫描”的算法简单易行,对于在计算机配料系统中自动建立接批性能控制表有实际应用价值。
Along with the application of computer for fiber dosage, a sharp increase is seen of the fiber dosage data in the database. In order to find out significant information from the database for control of fiber sorting on lot-to-lot basis, this paper firstly probes the database design method, analyzes the relationship between tables and entity property of tables in detail, and discusses the general description of the regulation for fiber dosage, and then puts forward a kind of ＂window scanning＂ algorithm which can automatically find out the regulation from the database according to its description. Moreover, application examples are given, which show that the algorithm of ＂window scanning＂ is simple and easy to operate, and has practical value in automatically creating tables which control fiber sorting and blending on lot-to-lot basis in a comouter system.
