Research On Data Exchanging Interface Based On SDO Of Railway Information Sharing Platform

Through more than 20 years' development, Chinese railway has got huge achievement in the railway informatization progress. Because of the lack of unified planning for railway in informatization, the co-communication and co-operation among various operational systems are poor, which lead to information in one system being hard to be used by other systems. And railway has numerous MIS (Management Information System), so if we develop the special information sharing system for every MIS, it will cause redundant construction and huge waste. It is significantly necessary to build a railway information sharing platform for the railway data-exchange work.Information sharing is based on data sharing. This paper actualizes data sharing by using data programming technology. Firstly, this paper imposes an investigation of the railway construction in information sharing platform and analyzes the existing problems. Then, by the research of the related standards and technologies in the latest dataprogramming--SDO (Service Data Objects), this paper proposes a data exchangemodel in line with information sharing requirements based on SDO, and designs the data interfaces. Finally, by using SDO technology, this paper actualizes a data-exchange example on the bases of the Railway Goods Tickets System and the Railway Goods Transport Marketing and Product Management Information System, which verifies the solution put forward in this paper.
