Design Of Signal System For Urban Rail Transit Based On Communication-Based Train Control

The moving block system is one of development technology of signal system for urban rail transit. It usually adopts the technologies of communication-Based Train Control, mainly including inductive loop and wireless spread-spectrum. By means of extensive reviews of the worldwide application models of CBTC system, this thesis discusses the basic principles of CBTC system and its main advantages over the Fixed Blocking System. Several key Moving Block System.Based on IEEE standard and domestic and overseas engineering practice, the data transportation system (DTS) is studied in detail. The definition, function, operational principle and design specification are presented. Based on equipment layout, frequency planning, electromagnetism Interference Analysis and project testing solve an issue of projects. The analytic results of system capability, reliability and safety indicate that this scheme can meet design specification.CBTC system is concluded here as an advanced train movement control system, though this thesis itself very much serves as a solid start to engage more profound research and project application in this important area in the future and some of the key areas for further work are high lighted.
