| This text aims at the Extrahigh Power Subcompany of SEPCO in Shandong power line road the region distributes of extensive and involve geography information complexity etc., have to look for a kind of with data management for the work platform of the center, the space data distribute type processing and adoption geography information(GIS), can melt calculator sketch and database at the integral whole, save and handle big charged barbed wire net space position and related attribute, with true, incorporate text and graphic of form to satisfy lose to change to give or get an electric shock equipments check to fix, circulate management to the request of space information.Applied C|S structure and the database technique of adoption Oracle, made use of VB preview to design to carry out the open type geography information system(Open GIS) system.Geography information system(Geographic Information Systems, brief name GIS) means soft in the calculator, the hardware support under, carry on to the attribute data of every variety resources linked to geography information and description of realistic objective world these resources characteristics collect, storage, management, operation, analysis, search, the statistics etc. function of technique system.It is organic to combine space position and related attribute of geography object and faces reality resources object to carry on search, index, statistics and analysis from geography space and the attribute data square, and result with the image, keep the form expression of view to come out, for the maintenance, analyze, decision provide important support platform.The open type geography information system(Open GIS) is meant calculator and under the correspondence environment, according to profession standard with connect(Interface) build up of geography information system.It makes data not only can be applying to flow inside the system, return ability between the system fluxion.Open GIS for making of different geography information system software have goodly operability with each other, and reach to distribute to carry out the path of information share in the database in the difference.Open GIS has the following characteristics:1.With each other operability:The conjunction, information commutation of different geography information system software has no obstacle.2.Can expand sex:The hardware can circulate on board in the calculation of different software, different file time, the function of its function and hardware platform become direct proportion;The software increases new ground of data and ground learning space learn data processing function.3.Technique public:The thought of opening is mainly public to customer, public source code and norm elucidation are one of the important pathses.4.Can transplant sex:At the software, hardware and network environment, independence's doing not need to be modified then can circulate on board in the different calculation.5.Also have in addition such as and permit sex and can carry out sex and be in conjunction with sex etc. characteristics.The Open GIS technique will make GIS always be placed in a kind of status of organization, open type and truely become the share in global scope that serves at the whole industry with social and carries out geography information with with each other the operation is a future network the GIS technique develops under the environment of inevitable trend.This system develops a contents to mainly include a system management, sketch maintenance, data management, manufacture technology management, tour management, examination management, maintain management, search statistics, change to give or get an electric shock a manufacture technology to manage nine main mold pieces. |
