Simulation And Research On Train Control Center Subsystem Of CTCS-2 Train Control System

Abstract Along with the rapid development of high-speed railway undertakings,CTCS-2 and CTCS-3 Train Control System have been used to practice on today's passenger line. Train Control Center is CTCS-2 Train Control system's core of the ground signal control equipment, is also the CTCS-3 Train Control System's downgrade back-ground signal control equipment. It provided for the train traffic order and ensured traffic safety.At present,the signal design of train control system needs continuous field tests to be improved. The result of this will consume a large amount of human and material resources. Replaced the entity and done the experiment with the simulation, it has characteristic such as being short of economy, security, test period.Now we use computer simulation technology to simulate various functions o(?)Train Control Center. We make it combine with actual line conditions and train simulation to test and verify line data instead of a considerable part of the field tests.The simulation not only can greatly reduce test costs,but also in a sense can give some suggestions to improve the efficiency of traffic.Not only sinulation can greatly reduce test costs, but also in a sense, give some suggestions to improve the efficiency of traffic.The former Train Control Center simulation system of lab didn't deal with the coding logic,and almost simplified station as section.So the whole system can not simulate lateral line running.Although the former CTCS-2 Train Control Center functional test simulation software can take comprehensive simulation of a station's coding logic,the system need to fill many files manually, and exhaust related information of each route of this station.The universality has been reduced greatly.The design takes resolving measures for questions of the former Train Control Center simulation design.The thesis designs and implements a train control center sub-system with practical current meaning. The system stores data and makes logic coding for all section and station track in the precinct of the train control center by dealing with relevant imformation of Design institute's basic data tables,and carries out the control display of section signals.The system supplies driving license for train along with the equipments of database server,interlocking,CTC etc.Traffic simulation of the whole line's complicated conditions,including forward run,reverse run,main line operation,lateral line running, line switching operation and so on, will be implemented.With the assistant of operation statistical analysis functions of dispatching center,the system will adjust the rationality of the design,and make improvement of the traffic efficiency be possible.
