Research On The Key Technologies Of Patrolling Line Of Communication & System Realization

Developing the LOC(line of communication) patrol system can greatly improve the management and efficiency of patrolling LOG. This paper constructs the object-oriented patrol data model, presents the knowledge-based method of making patrol scheme automatically, resolves the visualization in statistic data and spatial geographical information and attribute information, realizes the integration among distributed network databases of patrol information and the integration between Web and GIS. The research results have been applied to practice.Chaper I The research status of relative technologies of the patrol system is firstly introduced, then the problems and shortcomings existed in the patrol system of LOG are analysed, finally the research contents are expended, with which followed a brief introduction to the dissertation's architecture.Chapter II based on the analysis of available patrol data models, the primary object-oriented thoughts and modeling techniques are used to build the patrol data model. A conceptual model in patrolling loc is constructed. Abstract class is defined. Basic objects and associate objects in LOC patrol are illustrated in the form of class. Relations of these objects are figured out in class diagram. The characteristic of object-oriented patrol data model is summarized.Chapter III Classify the patrol knowledge into three levels, and represent them in BNF mode. Construct the base of patrol knowledge with the acquired patrol knowledge and effective management and organization for the knowledge. Reasoning mechanism , rules , level reason method ,reason process , are all discussed in detail. Based on the constructed patrol knowledge base, use the reasoning mechanism of patrol knowledge to realize the auto generation of patrol scheme.Chapter IV After analyse the requirement of visualization in patrol management, get all three contents of visualization in patrol . Then discuss the visualization in statistic data, spatial geographical information and the query of attribute data.Chapter V The integration among distributed network database and between web and GIS are researched because of the requirement, the B/S-based integrated system is realized and the application examples of this system are given.The remainder of this dissertation summarizes the research work and gives the future work of this research.
