Research of the Digital Communication System for CBTC Based on 802.11

The communication based train control (CBTC) system is an advanced train control system. It uses high accuracy of train locating, realizes a continuous automatic train control system. DCS system plays an important role in the information interaction between ground equipment and vehicle equipment in CBTC. Based on OPNET simulation console, this paper designs a DCS network, simulates its communication process, analyzes the simulation data of sending and receiving, evaluates the entire performance of the network, which can offer reference to designing and optimizing the DCS network.
