Design Of Train Control And Monitoring System For Dalian Metro Line 3

At present,China is in the golden age of rail development,China has become the world's largest urban rail transit market.All major domestic vehicle builders were made to speed up the process and customize vehicles,especially rail vehicles is how to achieve the core system-train control and monitoring system self-integrated development is especially important.However,urban rail transit train control and monitoring system so far the core technology operations,mainly in the hands of the foreign companies and research institutions,which seriously affected the further development of rail transit vehicles and foreign technical cooperation.In order to break through the technical barriers to foreign multinationals in rail transportation equipment,key technologies,to shorten the gap with the international advanced rail transportation equipment manufacturing industry,China rail transportation equipment industry is an urgent need in certain key technologies,proactive product development strategy,and as a key strategic industry innovation and competition,in-depth design and use.This paper introduces the development of domestic and international mainstream train communication network,compares the technical level,and then a detailed analysis of the current situation at home and abroad communication network applications and rail vehicles challenges faced.And analyzes the network structure,network and data network level MVB communication network.Key to the actual urban rail vehicle engineering project development as the basis,designed around the train control and monitoring system,especially for critical subsystems such as vehicle traction system,braking system,auxiliary power system control logic,and so the monitoring diagnostics detailed design instructions.Determine the communication interface of each subsystem with the train control and monitoring system designed software interface train control and monitoring system,the final completion of the train control and monitoring system of their own integrated development.
