Abstract： 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 businessoriented data management application services.
Key words : metadata separation; data management; data file; time series database
