China Railway Autonomous Service Integration System Based on ADS

More and more research has been focused on improving system expansion and data sharing abilities. of the original system. For China railway information systems, in order to follow its development, how to construct the newly effective information system is its important problem, the existing information service must be used in the newly system. In this paper, aiming at those problems mentioned above, a new system service integration method based on Autonomous Decentralized System is proposed. Based on Autonomous Decentralized System and its correlative technologies, this paper proposes a new integrated method based on Knowledge Data Base via Information Flexibility Descending Field (IFDF) Firstly, according to the information service feature, the definition and its logical functional structure of Autonomous Integration Node (AIN)is described, AIN is the key node to implement service integration. Secondly, this paper describes the flexible and rigid information formats, these information formats can be used to implements logical nodes data exchanging autonomously. Lastly, based on the paper´s research, China railway autonomous Service Integration System (CSIS) model is given out. Based on ADS and KDB, its on-line ability can be assured.
