Research And Implement On Power GIS Sharing Platform Based On SOA

The information in the power system construction process, because of existing information systems development at different times, operating system, system model, so different data formats, it is difficult for information exchange between systems, leading to various departments and business resources can not adequately Sharing, information sharing is not reasonable, self-contained part of the network and application systems, formed the formation of a large number of distributed heterogeneous "information island. "SOA (Service-Oriented Architecture) is a service-oriented software architecture model that can effectively support the development of geographic information services and applications to solve the heterogeneous distributed "information island" problem, in this new structure, business Construction is no longer required to correspond to a variety of information systems, but built from the ground directly to a variety of services, and build services to achieve all kinds of applications.Therefore, faced with the information silos and power system information integration of tightly coupled situation caused by the existing software development models and methods of information integration, ,a construction of loosely coupled SOA based Web services, GIS information sharing platform for power design was presented in this paper, and fully referenced EDA (Event-Driven Architecture) design of the model to a service-oriented Web services for the underlying data organization, select B/S distributed system architecture, The production of the original manage system and emergency command system were made standardization of their design basis of the original data integrity and compatibility, to clarify its functional requirements, interface definition and integrated analysis. The XML language was designed of interface for communication between Heterogeneous platforms. And through the service creation, deployment and registration, custom graphics and other services can only share, but also make full use of the existing production management system hardware and software resources to save development investment.
