Gsm-r Mobile Communications Systems In The Qinghai-tibet Railway Applications

GSM-R is the private mobile communiciation system for railway, which is based on the ETSI GSM,the second generation of mobile communiciation system, It has already come into use in Europe. With the development of transport, the Chinese railroad needs to build up a set of mobile communiciation system that match the request of Synthesizing communiciation and signal ,and this system can Satisfy the increasing the railroad need: the ambulation words sound business,data deliver the need of the business and guest the goods service business. At the time of choosing the new mobile communiciation system, Chinese railroad choose GSM-R as a developing direction.It is a valuable subject in practice to study the basic functions and systematic performances of the GSM-R system and verify its technical adaptability in Chinese-railway communication network. GSM-R system in Qinghai-Tibet as a new railway control mode have already developped its special advantage all newly, its strong ability of setting the net make the function of radio train dispatch more strong, the successful building experience will push the function of radio train dispatch into a new area.Currently, the line of jing-jin ,shi-tai,wu-guang,zheng-xi has already started spread the track construction continuously, the construction of GSM-R in the passenger transportation special line is at time. To the passenger transportation special line ,these research works has reference meaning.This text chooses the subject that Qinghai-Tibet road GSM-R system as a comprehensive ambulation correspondence platform carry out the function of radio train dispatch as mainly studying direction.With the practice of Qinghai-Tibet road 's GSM-R system ,this text introduce the GSM-R system ,and analyze the function of GSM-R system. Combining need for the GSM-R system, put forward a collectivity construction scheme , which contains GSM-R system configuration, radio dispatch design and GSM-R field strength coverage, the line network equipment of principle.Induce main apply of...
