RESUMEN
Objective To analyze informatization module requirements and to design system framework for manufacturing train hospital in 350 km/h speed Chinese standard EMU. Methods Using 350 km/h speed Chinese standard EMU as the design platform and medical experience in hospital and health informazation in warship as design foundation data, the informatization system requirements of hardware and software were discussed to figure out the rational framework design of hospital in train. Results The informatization system of the train hospital was divided into two components for external and internal communication. The external communication component consisted of telemedicine subsystem based on KU satellite communications, train dispatching subsystem based on train dispatching private network and military command subsystem based on special communication bands, and the internal communication component was made up of the hospital information subsystem, internal office subsystem, video supervision subsystem etc. Conclusion The framework design of the informatization system of the train hospital takes considerations on the compatability with military and civilian uses as well as the requirements for information exchange between information functional systems, which lays a foundation for the manufacture of the train hospital based on the EMU.
