Ajax Technology In The Power Gis Project

There is a development trend now, that be geography information system(GIS) which develops business to turn strongly circulates system integrate the nation information-based and knowledge-based economy of corpus, then the GIS application level and performance will be raised.Along with our country economy and society of fast development, the load of electric power system is more and more heavy, the network management of Power Grid becomes complicated. Because dynamic state of the Power Grid is multifarious, producing a network data flows also become huge, the electric power business enterprise's requested to have Fast, dependable and valid ability which making the reaction to the abrupt affairs. The variety multifarious and huge electric power system data most of which is geography information data, produces the GIS and make it growing up quickly. Ask for help from GIS, the electric power business enterprise can manage the great variety resources which distribute in the different place, do a decision to programming and construction of the Power Grid, and then carry out the management automation of electric power resources.At the same time, because of the technical fast development of the Internet, GIS gets into the Internet and the control of it need increment of the network long range. If it is said that the Internet emergence lets the development of GIS walk to ascend a new road, the raising of the AJAX technical on the Internet lets the GIS fly. The AJAX provides a technique of trying to solve the problem, how to make a GIS huge data to deliver effectively on the Internet. So far, the result for gaining is exciting.This thesis takes the electric power need and the GIS present condition as a basis, analyses and discusses the AJAX technique in the application of the electric power GIS:Frist of all, it takes GIS characteristics and development trend as basises, analyses the WebGIS under the Internet.Secondly, the relation taken getting between AJAX technique and WebGIS characteristics and weakness of fast development in the last few years as foundation, analyzed a dialectical result that is AJAX technique's development to WebGIS which leads to turn into the module has very important function to promote the standpoint.Finally, Managing according to the Power Grid resources oneself of characteristics: the amount of GIS data are huge to hand over with variety and multifarious, Combining currently project, and examining towards leading to carry on into the AJAX technical function in the electric power GIS analyzing, it gets an affirmative of conclusion.
