A Meta-model Based Modeling Method for Geographic Information Model in CTCS Hardware-in-the-loop Simulation System

Abstract

According to the requirement of hardware-in-the-loop simulation system for CTCS Level 3 (Chinese Train Control System Level 3), a meta-model based modeling method for railway geographic information is proposed in this paper. The modeling principle, modeling scheme and key technologies of this method are deeply explained and different modeling schemes are compared in detail. Using this modeling method, the railway geographic information can be expressed more concisely and completely, and the model can be extended and reconstructed more easily. The proposed model is now successfully used to provide effective support for the running of the train dynamic model.
