Embodiment 1

[0055] see figure 1 , this embodiment provides a GIS application method based on a distributed memory database, based on figure 2 Realization of distributed memory space data architecture.

[0056] The architecture provides data services for applications through control nodes, which are responsible for parsing SQL, distributing tasks, processing responses, and collecting results. This is the core part of the service provided by the entire system.

[0057] The data access and data editing functions are provided in a structured way in the data nodes, scheduled by the control node, and the data nodes are provided externally in the form of clusters, which can realize the separation of reading and writing.

[0058] Use management services to provide management and coordination for the entire system, and persist related configurations to provide high-availability services in an active-standby mode. The user can view the system operation status, monitor the key indicators of the s...

Abstract

The invention provides a GIS application method based on a distributive memory database. The method comprises the steps of obtaining a node range corresponding to data; loading graphs and attribute data thereof; building indexes of data and nodes; receiving a user request sent from a client side, and analyzing the request; determining target nodes according to a query condition corresponding to the analyzed request and the indexes; calling the target nodes to process the request through a structural interface; using the target nodes to process the request and returning a result; returning theresult to the client side. By means of the GIS application method based on the distributive memory database, services are provided to the outside in a clustering mode, and separation of reading and writing is achieved; meanwhile, the overall strong-consistency business support of the space, the attributes, and the topological structure under a distributive environment is achieved, and high real-time synergism is achieved; further, the management capability of a power grid platform is promoted to several billion levels, and efficient synergic management of the power grid data is achieved.

Description

technical field [0001] The invention relates to the field of power grid geographic information systems, in particular to a GIS application method based on a distributed memory database. Background technique [0002] With the continuous deepening of power business applications in various provinces, in recent years, the rapid growth of power grid resource data, continuous deepening of business applications, and gradual increase in visits have posed challenges to the GIS platform uniformly promoted by the State Grid Corporation of China. The original centralized grid GIS platform architecture exposed many problems, which restricted the development of grid GIS platform. [0003] The spatial data of the power grid is associated with various types and complex forms of equipment attribute data. At the data persistence level, it is stored by a relational database. In the relational database of the power grid, there are a large number of tables, generally hundreds of data tables, t...
