铁路GSM-R系统高速适应性测试及分析
High Speed Adaptability Test and Analysis of Railway GSM-R System
摘要
Abstract
The research and development of 400 km/h high-speed railway technical reserve can promote the technological innovation of high-speed railway in China.The service quality under high-speed conditions is directly associated with the business quality.The train control business carried by CSD and the transmission business of scheduling information carried by GPRS are both associated with operational control and dispatching of the train,which have an important impact on the safety of high-speed railway.At present,there is no evaluation standard for the service quality parameters of 400 km/h GSM-R system in China.To ensure the traffic quality and safety,the service data of railway GSM-R system under different speeds were harvested,including the minimum available receiving level,train control circuit data and GSM-R data.Transmission characteristics of these three kinds of indexes are analyzed,and the high-speed adaptability results of the railway GSM-R system at 400 km/h are obtained.The results illustrated that for the GPRS system of high-speed railway,the minimum receiving level is currently-92 dBm,which needs to be modified to-81 dBm at 380 km/h level and-79 dBm at 400 km/h level.The high-speed adaptability of column control circuit data and GPRS data transmission characteristics is strong,which have met the requirements of relevant standards.The research results of this paper lay an important foundation for the formulation of evaluation criteria for key technical parameters of 400 km/h GSM-R system,and provide reference for the next speed increase of high-speed railway in the future.关键词
