摘要
为了适应复杂多变的编码规则,统一和共享码段信息资源,提出了元码段的概念及其细分方法,分析了元码段的类型。阐述了基于元码段细分和元码段重构的混合式编码规则定义方法,分析了基于该方法的编码系统功能。对元码段实现方法、数据库设计、PDM系统集成模型等关键技术进行了研究。实例表明该方法支持定义复杂的编码规则,重用码段数据,可降低编码系统开发和维护成本。
In order to customize complex coding rules and to share coding segments, a concept of CSE was put forward. The subdivision method and types of CSE were presented. After studying the coding rule definition method based on CSE recomposing, the coding system functions were described. The key techniques such as CSE realization method,database design and PDM integration model were researched. Cases show that the method can support complex coding rules definition and reuse CSE da- ta,therefore the cost of development and maintenance of coding system is reduced.
