Research And Design Of Power Marketing System Based On Mobile GIS

The development of mobile GIS provides customer access to power marketing system even out of the range of enterprise LAN. The PDA possesses powerful function of data access and management, for embedded database and GPRS technology become popular. What is more, SOA (Service Oriented Architecture) based on Grid computing may be a new solution for combining Power Marketing System with Power GIS system. The flexible and secure Power Information Integration Platform can be constructed by conforming and absorbing mobile GIS technology, design based on modularization of service module and SOA technology. Many heterogeneous systems can be integrated in this platform. User can accessed this platform anywhere.This thesis analyses the trait and limitation of current Power Marketing System and gives a solution that is building the data interaction platform based on mobile GIS technology and integrating the GIS and marketing information system. It also discusses the system infrastructure and key points of the solution. More than that, this thesis gives some new points of view about designing concept of system platforms, for example the functional module is considered and joins the system platforms as the same class service pack as the information system. Obviously, this way may protect current IT investment effectively. The traditional design of PDA which is acted as client is changed. Client which locates in PDA exchanges data with Server Machine peer to peer. Compare with the traditional way, Server Machine not only queue for connection of client, but also access client forwardly. Meanwhile, this thesis shows some designs which are suitable for customer. For example, the design of network interrupt handling; compressing file with different algorithms according to their type and voice prompt of task for burst transmission, and so on. Attribute to the unique integration design of PDA, people can customize the function of PDA client, even the system platform has already put to use. It makes the Power PDA more economic. All of above measures can bring new system platform more function than integrating two current information systems simply. For example, dynamic management of checking attendance and real-time updating of electricity equipment data are functions which are hard to implement in either power GIS system or power marketing system.
