Segmented Opening Performance Test and Analysis of Vehicle-Ground Wireless Communication System in Urban Rail Transit
Wireless communication system transmits text,voice,video and other information to the terminal in the form of signals,which is widely used in the communication construction of urban rail transit.Combined with the transmission requirements of vehicle-ground communication,it has great advantages to build a vehicle-ground wireless communication system by using the method of subsection opening.This paper briefly analyzes the functional requirements of the vehicle-ground wireless communication system,and designs the overall architecture of the vehicle-ground wireless communication system.At the same time,the comprehensive application ability of the train-ground wireless communication system is tested.The test results show that the train-ground wireless communication system can meet the business needs of urban rail transit and can be popularized and applied in practical work.
