Interoperability test data graphical capture and analysis system based on multi-resolution models for the onboard equipment of CTCS-3 train control system

Onboard equipment of CTCS-3 train control system has to be executed the interoperability test by the independent third-party test bench before it running on the lines. During the test, it has a large amount and higher frequency in the data transmission, test phenomenon occurs on several visible interfaces and frequently, test data should be captured and displayed graphically in real time during the test, it should also be replayed graphically after the test, the fault in the test could be analyzed repeatedly, therefore it makes the data recording and analysis easier to read and estimate, help to generate final test result. In this paper, test data capture and analysis system is built based on multi-resolution modeling, related information is organized reasonably, provide the information detail that the tester concerns maximum, improve the simulation fidelity and testing efficiency. The system is implemented using Labview tools, and verify the simulation result.
