Abstract: During the process of CTCS-3 train control system vehicle equipment's simulation and test, the display interface has a huge amount of information involved. In order to divide the display interface into proper segmentations, so as the whole system can have a clear architecture, in this paper the authors propose a method which applies the multi-resolution model into the design of the interface, before the entire display system is built. Finally, with the simulating result of LabView, the method's applicability is proved, technical staffs' work intensity is reduced and they can focus on the cared content when they analyzed the technical process.
