| With the rapid development of Urban Rail Transit in China,domestic major cities build several subway lines.The network operation of Urban Rail Transit is being formed.Traditional single-line operation mode set up multiple systems in each line,which cause diverse system formats between different lines,unable to realize data sharing and contribute to the information islands between operation management.In order to implement the networked operation decision-making and emergency linkage command,the things to solve the problem of data resource sharing has become increasingly important.In accordance with this situation that the scale-up of Urban Rail Transit’s network operation and the urgent demand about achieving data-sharing,this article advances a concept of Urban Rail Transit data acquisition platform.Data acquisition platform includes data acquisition systems and data warehouse system,using the key technologies of data communication interfaces and data modeling to achieve the efficient use of data resource.Data to be collected in data acquisition platform present the characteristics of huge number and complex type,by classifying data information to and presenting unified interface standard type to solve the problem of line interface without standardization.After collecting massive and complex data into the data warehouse system,through the data analysis of business planning to determine appropriate subject field and implement data modeling.Relying on the research of data acquisition platform and combining with the actual situation of Tianjin Rail Transit,designed Tianjin Rail Transit data acquisition platform and implemented partial function to verify that the value of Urban Rail Transit data collection platform. |
