Research on Signaling System Scheme of Multi-network Integration of Metropolitan Rail Transit
According to the network and public transportation characteristics of the metropolitan area rails,the technical goal of integration of signaling systems is proposed,which is,the integration of existing C2/C2+ATO and CBTC systems and the integration of signaling systems using new interconnection technology.Based on the analysis of differences in technical level,working mechanism and system function between the ground and vehicle equipment of the existing mainstream CTCS and CBTC systems,the interconnection schemes of"ground-to-vehicle compatibility"and"vehicle-to-ground compatibility"are proposed.Combined with the current researches of relevant manufacturers,the new interconnection technology route of suburban railway is analyzed.
