[0002] On the premise that the power grid spatial information service platform adopts the large-scale centralized deployment method in the whole province, due to the large amount of grid spatial data and related attribute data in the whole network province, and the high concurrency rate of client applications in the large-scale centralized mode, the traditional Access to spatial data in the way of direct connection with the spatial database will bring huge pressure on the database server and network bandwidth
At the same time, it also greatly affects the efficiency of client users

The invention discloses an electric GIS (Gas Insulated Switchgear) cross-platform spatial data service system which is used for establishing a set of cross-platform deployed three-tier architecture spatial data service platform and a related client memory space database by adopting a cross-platform spatial data service engine and a local spatial database management technology. The electric GIS cross-platform spatial data service system realizes access and data scheduling to spatial databases, such as OracleSpatial and ArcSDE by using a standard HTTP (Hyper Text Transport Protocol) and adopting an expanded Apache Web server as a server; and a client adopts a GeoStar compatible spatial database access interface so as to realize rapid acquisition and memory-based rapid access to the server spatial database, therefore, the spatial data acquisition efficiency when a large amount of users concurrently access a power grid space information service platform is met and the user experience is promoted.
Description
technical field [0001] The invention relates to spatial information technology, which is a data service middle layer technology for grid spatial data management, scheduling and buffering, and in particular to a cross-platform spatial data service method and system for a power GIS system. Background technique [0002] On the premise that the power grid spatial information service platform adopts the large-scale centralized deployment method in the whole province, due to the large amount of grid spatial data and related attribute data in the whole network province, and the high concurrency rate of client applications in the large-scale centralized mode, the traditional Accessing spatial data through a direct connection with the spatial database will put enormous pressure on the database server and network bandwidth. At the same time, it also greatly affects the efficiency of client users. Contents of the invention [0003] The present invention provides a [0004] In order...
