Abstract

General simulation requirements within the train control system simulation framework were described. Dynamic characteristics were modelled at four resolution layers, ranging from low to very high resolution. The research focuses mainly on the dynamic behaviour and simulation representation at the signal emulation layer. The Balise Transmission Module Hardware-In-the-Loop simulator was justified with respect to dynamic behaviour modelling. Furthermore, the relationship between Balise Transmission Module dynamic characteristics and train speed was verified by simulation and test data. The speed factor is derived and analyzed. Finally, quantitative evaluation issues of high-speed adaptability were explored based on the deduction of decoding failure probability under a certain bit error rate and the availability targets for a certain line.

BTM has been successfully used in China Passenger Dedicated Lines (DPL) with the maximum speed of 250Km/h and high-speed lines with a maximum speed of
