Study On Incremental Train Control System Based On Wireless Communication In Qinghai-Tibet Railway

The worldwide noted Gulmud-Lhasa Depot of the Qinghai-Tibet Railway was initially constructed within 2001, completed on July 1, 2006, and put presently to trial run. Owing to the harsh natural conditions of the Qinghai-Tibet Plateau, the information system of the Qinghai-Tibet Railway is required to cater for the needs that the Gulmud-Lhasa Depot should be automatically maintained and that the overall operation time shortest. Hence, it is of vital significance that the appropriate train control system to guarantee the effectiveness of safe operation be chosen. The Incremental Train Control System produced by American General Electric Company was finally adopted in Qinghai-Tibet Railway, a system that is based on GSM-R communications system, and that is all-directionally applied in our country for the first time.The Ministry of Railway in our country makes the decision that GSM-R and train control system based on wireless communications are oriented as the technical policy to satisfy the leapfrog development of the railway industry. As an experimental unit engineering, therefore, it is very important to embark on some research about this system. The mastery of techniques relative to train control system based on wireless communications, which is applied in Qinghai-Tibet Railway , ensures the technical maintenance; the command of the advanced technology in this field to be imported, innovated and applied, serves to promote the level of train control system in China.The paper mainly covers the following important points:Firstly, the trend of train control system is predicted on the basis of the research into the application and evolution of train control system both abroad and home.Secondly, the system structure, the operating principles, the system characteristics, and the core technology of train control system, which is based on wireless communications, are analyzed.Thirdly, according to the planning of communications signal system in Qinghai-Tibet Railway, the techniques relative to Incremental Train Control System are briefly introduced, and the major concerns in the planning device...
