面向输变电工程数据存储管理的分布式数据存储架构

针对输变电工程数据的多源、异构、迭代更新和集成应用导致需要巨大存储空间且不利于数据挖掘分析的问题,提出了一种面向输变电工程数据存储管理的分布式数据存储架构.该架构基于元数据模型对输变电工程的工程地理信息、三维设计模型和文档资料三类数据进行细化,并根据不同数据存储模式的不同,设计了一种分布式存储架构分别处理各种数据.系统实现与仿真实验结果表明,所提出的分布式存储架构在保证存储效率及数据完整性的同时,也能保证数据的安全.

Distributed data storage architecture for data storage management of power transmission and transformation engineering

Focused on the huge requirement for storage space due to multi-source, heterogeneity, iterative update and integration application of power transmission and transformation engineering data, which is not conducive to data mining and analysis, a distributed data storage architecture for the data storage management of power transmission and transformation engineering was proposed. In terms of the metadata model, three kinds of data, i.e. engineering geographic information, 3D design model and documents of power transmission and transformation engineering, were refined with the proposed architecture. According to the storage modes for different data, this distributed storage architecture was designed to handle various kinds of data. The results of system implementation and simulation experiments show that the as-proposed distributed storage architecture can guarantee data security, storage efficiency and data integrity simultaneously.
