Integration Research of Communication Based Train Control and Computer Interlocking in Urban Rail Transit

Abstract

Abstract. By analyzing the interface information of CBTC and computer interlocking, the process of train control was abstracted as a closed-loop control model based on communication mode of train-to-train. Considering the whole fail-safe of the integrated signal system, designed four operating modes that would have strong compatibility. Through software simulation, the model tested its the validation and the integration proved its feasibility. The results indicate that this kind of integration can be available in the signal system of urban rail transit.
