Study On Technical Scheme Of Intercity Railway Signal System

Zhengcheng Intercity Railway,as an inter-city railway connecting Zhengzhou with the international airport,has a very strong responsibility and play.It is mainly due to its unique advantages,including the high speed and high safety of the high-speed train.With the advantages of short running distance,large starting capacity and flexible organization and control,the city rail can also realize the China Railway System Control Level 2(CTCS-2)train control system,which can make the train The driving information is transmitted in real time through the configuration of the track circuit plus the transponder to ensure the timely transmission of information between the ground and the train.Zhengji City Railway is an important symbol of the prosperity and development of Zhengzhou City Railway.It is also a key link in the construction of the entire city railway.It is also the leader in the early realization of the rapid transit operation of the urban rail railway.For the operation of the city railway and train driving,to ensure its safety and efficient operation,the most important thing is to ensure the accurate operation of the signal control system.The management and operation of the signal control system is very important for the safety and effective operation of the rail transit.Therefore,in this paper,the system configuration,technical scheme and real-time link of the signal control system will be combined to conduct comprehensive research and analysis.This paper will combine the management example of Zhengji Intercity Railway on the signal control system,from the system configuration,technical route and construction implementation to the development and application of the signal system and CTCS-2+ATO(Automatic Train Operation)Operation control system)The design and application of the program control system is discussed.It mainly focuses on the following aspects: one is the overall scheme of the signal system;the other is the centralized management and scheduling scheme;the third is the design scheme of the train control system;the fourth is the data security network management scheme;the fifth is the occlusion And the track circuit scheme;the sixth is the computer chain control system scheme,etc.From these layers,in the actual operation process of the intercity railway,the design and implementation of the signal control system are studied and analyzed.This paper aims to study the design and application of the signal system of intercity railway operation by combining actual cases,and then propose the composition and engineering implementation plan of the system,which can provide guidance for the implementation of the design of other rail transit operation plans.
