Research On The Data Standardization And Database Design Of Urban Rail Network

With large volume, fast, punctuality, reliability, comfort and many other features, urban rail develops rapidly in many cities of our country. Although the “linear control” mode can maintain the basic need of operational at present, it will not gradually meet the actual demand with the capacity expansion and the expansion of the line of urban rail network, for which we should as quickly as possible to establish the urban rail network that can achieve integrated management, coordinated deployment, emergent command and information sharing. Changing the "linear control" to "network control" has become an inevitable trend of urban rail development. However, faced with the problem of heterogeneous data between the lines, to develop the data standard and design the corresponding database is the primary task of constructing the command-platform. This paper has studied the data standardization and the database design of urban rail network according to the actual construction of the command-platform of Guangzhou urban rail network.This paper firstly themed to the data standardization of urban rail network, in the basis of understanding the need and business features of urban rail network, combined with the business model and analysis of the existing lines to complete the extraction of data elements. To finish the data standard, this paper went on to standardize the property and the description rule. According to the need of command-platform of Guangzhou urban rail network, this paper also studied the design specification and the principles of database of urban rail network.Finally, this paper applied the research in the construction of command-platform of Guangzhou urban rail network and develop the data standard for the twelve subsystems. Broadcast system as an example, this paper described the implementation process of the data standard in detail and applied the database specification in the database of Guangzhou urban rail network.This paper would provide a reference for the construction of urban rail network of other cities and it also would provide a reference for the data standardization and the database design specifications of other industries.
