Development Of Train Passenger Network Service System

By the end of 2016,the length of the railway in operation in China exceeded124,000 kilometers,and the high-speed railway had exceeded 22,000 kilometers.Railway has gradually become the first choice for long-distance travel in China.However,there are some shortcomings in the way of entertainment,such as fixed mode and single content.Can there be a way to provide personalized service for passengers on trains?With the rapid development of the Internet,the Internet has become a necessity in people's life.How can passengers on trains enjoy better Internet services?Because the high speed train body has good sealing performance and fast running speed,the quality of the wireless network in the vehicle is poor.This paper is devoted to the research of train passenger network service system in train communication network,through which passengers can provide stable network service on train.This paper introduces the development status,characteristics and related technologies of train communication at home and abroad.Based on the analysis of the specific requirements of the Railway Corporation,the overall design of the train passenger network service system architecture is carried out.The system architecture is divided into three layers: the first layer is "intra-vehicle LAN layer";the second layer is "vehicle-ground Internet layer";the third layer is "ground operation and maintenance management center";and then the three layers are set up in detail.Plan.The key servers and compartment servers in the LAN layer are designed,and the hardware and software of the core servers and compartment servers are designed according to the physical,electrical,performance,function and reliability indicators.The platform interface design of operation and maintenance management platform in the ground operation and maintenance center is designed.The function and performance of the developed system are tested and analyzed.According to the test and analysis results,it can be concluded that the system function,performance and performance meet the expected requirements of the system design in the current server software and hardware,network environment.
