The 5T system uses the intellectualization, the network, the informationization technology, rail line constructs the 5T system detector station in, realizes the above-ground equipment to in the passengers and cargo vehicles movement security dynamic examination, the data set, the networking movement, the long-distance monitoring, information sharing. Remarkable will sharpen the railway transportation safe guard ability. Through installs on the experiment site line TPDS、TADS、TFDS、TCDS、THDS after the equipment and the small scope networking movement, the practice indicated that, These advanced check-out facility networking utilization will examine the work to the row by the tradition to modern, by human-controlled to machine will control, has the huge function by the extensive management to the intensive management revolutionary transformation. However, has also discovered some questions in various systems independent networking operation. More prominent is, in view of the fact that scene situation uncertainty and automatic detection technical order of complexity, single kind of check-out facility failure prediction rate of accuracy still not entirely as desired, in the short-term will have to obtain the substantive breakthrough to face the dual pressures which the technical challenge and the equipment investment expenses will increase. Therefore urgent needs is separated in the time and the space each kind of examination information organic connection, carries on the entire journey tracing and the synthesis judgment, can the more effective display 5T system safeguard vehicles movement security function. This article mainly is composed by several parts, includes the primary coverage in 5T system conformity demand this part is: 5T system outline, conformity demand as well as conformity goal and so on; The 5T system conformity technology part has covered the 5T system overall construction, the data processing flow, the monitor network design as well as data level conformity, interface standard contents and so on unification; Finally is the choice takes the application part design example: TCDS vehicle data communication part design.
