Map data storage method and system

图谱类数据存储方法和系统

Abstract

本发明涉及一种图谱类数据存储方法和系统,其方法包括:根据接收的图谱类数据获取对应的电力系统资源的统一资源标识、量测值ID和数据信息量值;根据预设的电网模型库、电力系统资源的统一资源标识、量测值ID和数据信息量值获取图谱类数据的数据特征信息;获取图谱类数据的统一资源标识,将图谱类数据的统一资源标识和数据特征信息进行组合存为逻辑中心点文件并存储于分布式文件系统的命名节点;将图谱类数据存储于分布式文件系统中的数据节点。用户访问图谱类数据时,根据数据特征信息或图谱类数据的统一资源标识查询命名节点的资源列表,并快速检索出对应的图谱类数据,无需解析,也能支持单独对图谱数据的快速检索,提高了数据访问的效率。
The invention relates to a map data storage method and system. The method comprises the following steps: acquiring a uniform resource mark of a corresponding electric power system resource, a measured value ID and a data information amount value according to received map data; acquiring data characteristic information of the map data according to a pre-set power grid model library, the uniform resource mark of the electric power system resource, the measured value ID and the data information amount value; acquiring the uniform resource mark of the map data, and combining the uniform resource mark of the map data and the data characteristic information to form a logic central point file, and storing the logic central point file in a named node of a distributed type file system; and storing the map data into a data node of the distributed type file system. When a user accesses the map data, a resource list of the named node is inquired according to the data characteristic information or the uniform resource mark of the map data, and the corresponding map data is rapidly searched and does not need to be analyzed; and the method and system also can be used for rapidly searching the map data independently, and the data accessing efficiency is improved.
