[Abstract]:At present, the main carrying data of the wireless communication system in urban rail transit are: train control information for train safety, video monitoring information for subway security, and PiS information for passengers. Monitor the train running status of the vehicle fault information, etc. In recent years, 802.11-WLAN technology is widely used to transmit all kinds of vehicle-ground information in the industry. However, due to the bandwidth and transmission rate of the technology, The influence of external interference and other factors such as WLAN technology can not meet the needs of all kinds of vehicle-ground information transmission, so exploring a new and efficient wireless communication technology is to meet the urgent needs of train safety operation and passenger service. This paper first analyzes the existing problems and current situation of WLAN communication technology application in rail transit industry, and then analyzes the technical characteristics of LTE and the feasibility of its application in the industry. From the theoretical level, the differences between the two technologies and their advantages and disadvantages are obtained. On this basis, the real measurement platform is built in the real environment of the rail transit project, and the relevant technical performance parameters are obtained from the actual engineering environment. Finally, the feasibility and correctness of the LTE technology in the ground wireless communication system of the rail transit vehicle is verified. According to the conclusion of the research, the application of LTE technology in the ground wireless communication system of rail transit vehicle can solve the problems that the WLAN wireless communication system is easily interfered by external factors, the transmission service is limited by bandwidth, and the packet loss is easy to occur in the course of high-speed train movement. It provides theoretical basis for the application of LTE technology to urban rail transit.
