Design Of Architecture Of Transportation And Location Service Support System

With the development of society and economy,the demand for satellite navigation is increasing.Although GPS navigation system has been more completed,for security reasons,the independently controllable satellite navigation system has become a necessary safeguard for national economy and society.The Bei Dou Navigation System(BDS)provides the foundation for the development of domestic location service industry.Compared with the foreign satellite navigation system,position report and short message service are provided as the unique features that the BeiDou Navigation System owns.The characteristics reflect the top-level design of BeiDou and the ability of scale development in the future.This paper is mainly focused on overall architecture design based on BeiDou navigation logistics transportation and location service support platform.First it has carried on the design of the overall architecture of the system,mainly designing from the system architecture,composition,application model,business model.Then,it carried on the design from the composition,performance index of the database,the system USES distributed database,real-time memory database,structured database,spatial database system architecture,database content.Finally,the system designed for its function module and the functions of the system implementation were classified.From the application gateway,alarm gateway,application service,operational support,GIS,data service aspects,the modules were designed.The system adopts cloud computing architectures,combined with gateway technology,and build generic network information access and integration gateway to block access terminal difference.Platform is used to provide application service engine to offer the runtime process scheduling services between each business system and the system modules,and provide customized business process secondary development interface.Provide data service engine service,shielding storage system differences and the difference between the data structure for the upper business system to achieve all kinds of heterogeneous data storage and query service.At the same time,the platform provides the GIS map service and interface display functions,including authority,operations management,network management and some main functions of BSS management services.Support platform is designed for the high reliability of the elastic extension and service platform of computing and storage resources,and to ensure the isolation and security of every special system,so as to lay the foundation of the subsequent service extension and scale development.
