With the rapid development of China's economy, long-distance pipeline network to play an increasingly important role in the national economy. However, for a long time, the pipeline information and more in the form of drawings, charts and cards recordkeeping manual management, manual management mode and management tools led to the low efficiency of management, the ability to integrate data resources and poor, when punch Stolen the corrosion perforation accident, the staff is difficult to achieve a timely manner. Pipeline enterprise, integrated information management platform for the construction of the integration of GIS technology and modern computer technology is imminent. It is based on the above, we designed based on client / server architecture, long-distance pipeline information management systems. On the server side, SQL Server 2000 relational database management system, to achieve the storage and management of spatial data and attribute data required by the system, and by means of a spatial database engine, the ArcSDE 9.2, reached to access and operate massive data purposes. Client using the Windows operating system, as the development language binding ActiveBar 2.0 ActiveX control in Visual Basic 6.0, the design of a friendly human-machine interface, and use of the GIS in secondary development of GIS tools MapObjects 2.2, these The features include: layered geographic map of oil pipelines and the surrounding environment, online and print output; massive spatial data, attribute data and monitoring data storage, query and analysis; geographic layers, geographical elements and the corresponding attribute information any add, delete, and modify. Currently punch Stolen phenomenon is very serious, in order to effectively prevent and curb the occurrence of such emergency incidents, two aspects of the existing system of pipeline enterprise improvement. On the one hand, the system combined with the existing monitoring system, to achieve real-time monitoring of the pipeline operating parameters, data collection point accurate positioning system automatically pop up when the pipeline leaks and alarm information, and on the geographical map highlighting the location of the leak and the surrounding environment to meet pipeline leak intelligent alarm, leak location quickly locate requirements; instead of the road the other hand, taking into account the weather, heavy traffic conditions and commercial activities of the travel time, the proposed use of path virtual length actual the idea of ??the establishment of the length, the the repair trip time model, combined heuristic function optimized Dijkstra algorithm, the system searches for repair and highlighted on the map the optimal repair path between the workstation to the leak point, solve the rule of thumb in the past acquired the shortest path and actually do not conform to the problems, which greatly reduces the pipeline leak caused economic losses of the enterprise and the pollution caused by the natural environment. Nearly two years since the system has a unique space for data storage, management and analysis capabilities, accurate, effective leak point positioning optimal repair path search function, the information management platform runs in Storage and Transportation Company of Sinopec oil generate significant economic and social benefits.
