Description
Technical field
It is more particularly to a kind of patterned based on GIS distributions the invention belongs to network Web GIS data display technology fields
Data message stream display system and method.
Background technology
The management of electric power system and its facility, power supply facilities device attribute data, operation of power networks data and use both it be related to
Family information, the empty data such as the geographical position of power supply facilities are further related to, further refer to power supply system network structure and opened up with network
Flutter, its information adheres to being described based on relational data for the routine such as the device space, electric physics space, geographical space, manifold separately
Information management system be difficult to reflect being overlapped mutually, bringing disaster upon conjunction and mapping relations for this more spatial informations, so both had conventional
Information management function, especially but also with the description of geospatial information, storage, analytic function GIS-Geographic Information System is theoretical, side
Method and technology, it is introduced into electric power system information management, and forms all kinds of electric power GIS application systems.From power system network knot
Structure sees that distribution system is the most complicated, is that electric power GIS applies most active object.
Distribution Power Network GIS (this paper abbreviations " distribution GIS "), it is computer graphics techniques, database technology, net
The integrated application achievement of network technology and geographic information system technology.Relative to regular distribution mis system, distribution automation system
(DA), its maximum feature is the description based on geospatial information specific to GIS-Geographic Information System, storage, analytic function, real
The spatial geographical locations of existing power distribution network facility and the mutual mapping of distribution facilities and equipment and service data and unified management.Meanwhile
The distribution facility geographical network formed using distribution GIS and the geometric network further formed, locus between facility is described
Relation and connected relation, laid the foundation to realize based on all kinds of distribution specialty analysis with net topology.
Data exchange between GIS often cannot be realized perfectly.This may be because many reasons such as system not
Compatibility, numerical accuracy difference, intermediary's file format and software limitation etc. several respects the reason for.So select suitable power distribution network
Data-interface, it can preferably realize application of the generalized information system in power distribution network.
Because centralized GIS can not be efficiently solved at software, data format, storage model and the data of each system use
The compatibility of reason mode, enter the shared and comprehensive data analysis of effective exchange of row information.
Network technology is applied in GIS at present mainly three kinds of centralization, C/S model and B/S patterns tactic patterns.
But the GIS of C/S structures can carry out the effect of information management and information sharing very well, many system operations are good
Good, but as the range of system application increases, C/S model has that professional platform independence is poor, maintenance upgrade difficulty and system resource redundancy
The problems such as big is spent, its closure makes people be difficult to set up complete information network system.Therefore, the GIS of this pattern has been
The requirement of user can not be met.
With the development of Internet technologies, the B/S tactic patterns arisen at the historic moment more have autgmentability compared to C/S structures, it
Solve C/S model problems faced, meet requirement of the user to information management enough.Its operating mechanism is still using distributed
Processing, but the Web page that user interface will be presented in entirely browser.Its user interface possesses friendly and uniformity, easily
In operation, and professional platform independence is high, is easy to extension, change and the management of system and the installation of software, upgrading of customer group, this
Analysis is mainly discussed with newest Web GIS modes.
