Research and design of data communication subsystem of urban rail transit CBTC system

Abstract With the intensive development of urban rail transit in China, has increasingly become preferred mode transportation for citizens due to its convenience and speed. The design construction an efficient highly reliable system urgent requirement construction. This article mainly introduces research data communication subsystem CBTC system, intends provide some ideas directions studying system. uses a variety methods, such as consulting literature information on trademark suppliers. status is analyzed, importance necessity entire are analyzed. experimental results this show that design, application engineering DCS accounts 55%, complex, environment changeable, occupying important position. When problem, it may cause drive failure, affect normal functions, greater losses, even huge safety accidents. Therefore, reasonable, safe great significance.
