摘　　要：针对现有嵌入式工业计算设备的数据分散、管理不足等问题,提出了一种基于元数据分离的数据管理体系结构。融合数据特性需求,设计了一种数据统一标准化处理的规则库,构建了元数据信息组织模型、索引存储结构及标准格式的数据文件,实现了数据文件与元数据分离存储的管理模式,将数据文件存储至索引目录磁盘,元数据信息实时写入时序数据库。初步开发了数据管理的应用原型系统,提升以元数据模型为基准的数据分级组织管理能力,实现数据互联互通,提高以业务为导向的数据管理应用服务效能。Aiming at the problems of data dispersion and insufficient management of existing embedded industrial computing equipment,this paper proposes a data management architecture based on metadata separation.Converged the requirements of data features,a rule base for unified and standardized processing of data is designed,the metadata information organization model,index storage structure and standard format data files are constructed,and the management mode of separate storage of data file and metadata is realized.The data file is stored to the index directory disk,and the metadata information is written to the time series database in real time.The application prototype system of data management is preliminarily developed,to improve the capability of hierarchical organization and data management based on metadata model,realize the interconnection of data,and improve the efficiency of business-oriented data management application services.
