Xu Jie · Communication and Transportati0n Systems Engineering and Information · 2005
In essence, railway intelligent transportation system (RITS) is an unity which is founded on the basis of person distribution and physical distribution. The information-shared platform of RITS is the center, through which the sub-systems communicate with each other in the RITS. On the basis of studying the demand of information searching of all railway departments and customers, the information-shared system is studied in the paper. Firstly, the appropriate architecture of information-shared system of RITS is put forward based on the current distributed computing architecture. Then the merit and defect of component software technologies are investigated, therefore, the key technologies of constructing information-shared system are selected. Subsequently, the data-integrated scheme of system and method of integrating data from deferent database are researched. At last, the general system architecture of the information-shared system is constructed.
