Application of Remote Monitoring System in Urban Rail Transit Construction Project Based on 5 G Technology

Wide coverage of distributed worksites of urban rail transit construction projects induce massive rail transit data,however the current remote worksite monitoring system based on 3/4 G technology has problems such as limited transmission capacity,poor computing capacity,and poor real-time performance,which makes the system unable to adapt to the rapid development of urban rail transit construction.The importance of constructing a rail transit smart worksite monitoring system based on 5G technology is analyzed,and the systematic structure,5G transmission network architecture and functionality of each module are introduced.This system adopts multi-layer,multi-node structured distributed smart worksite monitoring system,using deep learning technology to strengthen the calculation,meanwhile,utilizing 5G technology to realize data transmission between worksites,supporting real-time transmission with large-capacity and ultra-high-definition video data,which enables real-time monitor data analysis,accurate prediction of risks,and improvement of management efficiency and emergency response capabilities.The performance of Guangzhou Metro pilot application shows that the system can meet the demand of multi-line and multi-worksite of urban rail transit projects.
