Layout and Function Realization of Continuous Large-number Turnout Balise on High Speed Railway
Large-number turnout of high speed railway is an important infrastructure to improve the transportation efficiency of stations.The train control system must control the train-ground information interaction in combination with the layout characteristics of large-number turnouts to ensure that trains run laterally at specified speeds on large-number turnouts.This paper carries out systematic research by analyzing the setting and message transmission principles of large-number turnout balise and in combination with the control logic of onboard equipment under a specific code sequence.On the premise of not changing the basic architecture of the existing CTCS system,through theoretical analysis,scenario study,simulation verification and other methods,this paper proposes and fully verifies the layout principle of continuous large-number turnout balise in high speed railways and the control scheme of large-number turnout balise message.The scheme effectively improves the operation efficiency of trains laterally passing through the continuous large-number turnouts in the"curve-in and curve-out"scenario and further enhance the control capability of the train control system in complex operation scenarios.
