Ltd, Chengdu, Sichuan 610031, China) Abstract:Research purposes:The studies are done on the main characteristics of communication system design, the main applied innovations and effects after the system being put into use for theMetro Line 2 for the purpose of providing experience and reference to construction of communication system for urbanmass transit in China. Researchmethods:The comparison and research are done on the aspects of communication newt ork technology, system constitution forGuangzhouMetro Line 2 accoding to the operational requirements and the development of communication technology. Research results:The technological choices and network constitution are put forward, which can largely reduce the investment in communications system. Research conclusions:The study should be done on the problems in designing the communication system when designing a new Metro line. The proposals aremade that the skilled and experience integrator should be hired to control the whole construction process of communication system, the U S of wt o hours should be equipped to the transm ission system, w ireless system, telephone system and main clock in control center and U S of one hour to the other syst
