基于对象的铁路公用基础信息编码方法

摘要

基于已有的信息编码方法,结合生产制造业和产品的编码经验,提出基于对象的信息编码方法.该方法将铁路公用基础信息作为对象,采用基于对象的方法,分析对象的属性和对象之间的关联关系,形成铁路公用基础信息分类体系.根据分类体系构造类别码.分析对象的基本属性.根据选取的属性构造类别码和辅助码.采用专家知识库和优化算法优化选取适于编码的属性,利用对象的继承性,形成编码模型.根据编码模型和编码规则,将类别码、属性码和辅助码组合在一起形成信息编码.采用该方法对铁路车站信息进行编码,验证了该方法的可行性和有效性.%On the basis of exiting information coding method, combined with the experiences in manufacturing and products coding, an object-based information coding method was proposed. With railway public basic information as object, the object-based method was used to analyze the object attributes and the incidence relations between objects, and to form railway public basic information classification system. Category code was constructed on the basis of classification system. The basic attributes of the object were analyzed. Expert knowledge base and optimization algorithm were used to optimize and select the attributes suitable for coding. Category code and additional code were constructed according to the selected attributes. Object inheritance was used to form coding model. According to the coding model and coding rules, category code, attribute code and additional code were combined together to form information coding. The information of railway station is encoded by this method, which has verified the feasibility and effectiveness of the method.
