|
摘要
为了提高火电厂数据存储与管理的效率,考虑到火电厂数据信息复杂、多样和密集度大的特点,以及现有空间数据引擎存在通用性和可移植性的问题,该文针对性设计了一种面向火电厂的空间数据引擎,以此来管理火电厂的数据信息。首先建立了三维虚拟火电厂结构体系和空间数据引擎的架构,然后重点剖析了空间数据模型、空间存储、空间索引、空间查询等空间数据引擎的关键技术,在此基础之上,通过实例验证了所设计的空间数据引擎的可行性和有效性。
To improve the efficiency of data storage and management in thermal power plants,data information's characteristics of thermal power plant with complexity,diversity and high density,and the existing spatial data engine cannot meet the data management requirements of thermal power plant,this paper proposes a spatial data engine for thermal power plant to manage the plant data information. Firstly the framework of 3D dimensional virtual thermal power plant and spatial data engine was set up,then analyzes the key technology of spatial data engine containing spatial model,spatial storage,spatial index,spatial query,etc. On this basis,feasibility and effectiveness of the spatial data engine was verified through the example.
