Real-Time Analysis of Block Mode-Communication-Based Train Control System Handover Using Colored Petri Net

Abstract:

The mode switching time delay of the block mode-communication based train control（BM-CBTC） multi-mode train control system has a great impact on the operation efficiency of urban rail transit. First， this paper analyzed the function and process of mode switching in the BM-CBTC system. Next， it established a mode switching model based on coloured Petri net （CPN）. Then， it studied the real-time performance of mode switching at different BM design operation intervals. The experiments show that the switching time delay increases with the increase of BM design operation interval， and the train operation delay can be within 5 minutes when the BM design operation interval reaches 2 minutes. The established CPN model also offers a reference for the real-time analysis of mode switching in other multi-mode train control systems.
