Performance analysis of communication network for the CBTC system
Communication based train control (CBTC) system is a safety critical system, and several factors in the system demand for new design and implementation solutions. Combining some software or hardware errors, a dual redundant network is proposed. Moreover, framework and working mode of the network are introduced. The paper evaluates the reliability in theory. A simulation is realized to test how the performances are improved once the dual redundant network is used. It is demonstrated that this network configuration can effectively improve the reliability of the system. In the working mode of hot standby, it even reduces probability of delaying and missing messages.
