摘　　要：提出一种融合框架和方法,用于解决复杂装备全生命周期数据的多源异构性带来的数据冗余、不一致和索引困难问题。该框架包括自上而下的数据模式融合、自下而上的数据实体模式生成和动态融合全生命周期数据层3个步骤。通过建立顶层数据模式、生成数据实体模式并配置主码转换规则和数据对象属性补全规则,实现全生命周期数据层的动态融合。经工程实践验证,该方法能够有效处理复杂装备全生命周期数据的多源异构性,优化数据融合过程。A fusion framework and method are proposed in this study to address the challenges of data redundancy,inconsistency,and indexing difficulties caused by the heterogeneity of multi-source data in the entire lifecycle of complex equipment.The framework includes three steps:top-down data schema fusion,bottom-up data entity schema generation,and dynamic fusion of the entire lifecycle data layer.With the establishment of a top-level data schema,generating data entity schemas and configuring rules for primary key transformation and data object attribute completion,the dynamic fusion of the entire lifecycle data layer is achieved.Engineering practices prove that the proposed method is effective in handling the heterogeneity of multi-source data in the entire lifecycle of complex equipment and optimizing the data fusion process.
