The Design And Integration Of High-Speed Train Operational Traction Simulation System Based On TCN

In recent years, China’s high-speed railway business is developing rapidly, not only realizes the domestication, but also exports a variety of technologies to foreign countries. The study focuses on CRH3EMU, aims at buliding the high-speed train operational traction simulation system based on TCN network.The paper lucubrates MVB bus and real-time protocols of TCN first,proposes the system’s overall design.The system consists three parts:traction simulation module, driving position and train control center, it uses MVB bus to realize the transmission of traction data on the TCN, thus ensuring its facticity, real-time and expansibility.According to the plan the study designs the simplified TCU as the interface between traction models and TCN, which can monitor the traction data. Than builds the physical traction simulation platform based on LabVIEW,which realizes the dynamic simulation of tractive load, constitutes the traction simulation module with TCU.After that the study integrates traction simulation module,driving position and train control center,adds traction control and section customize functions,finally builds the real-time and efficient high-speed train operational traction simulation system.The study tests the function and performance of the system at last,the result is satisfactory.The system restores the high-speed train’s network environment,which has a good performance of real time,surveyability and expansibility.The system can provide platform for the research on the running train traction.
