Rail transit is a key component of urban transportation,which can effectively alleviate the traffic pressure of large and medium-sized cities.The complexity of urban rail transit lines and high operation frequency have brought great obstacles to rail transit monitoring and affected the safety of rail transit operation.This paper proposes the design and research of urban rail transit monitoring system based on big data technology.The design system continues to use the existing system hardware units,and develops and improves software modules based on big data technology,including redundant communication control module,rail transit train positioning module,rail transit operation data acquisition and mining module and rail transit operation anomaly monitoring module.Through the collection,processing and application of operation data,the operation status of rail transit is determined,and the operation of urban rail transit monitoring system is realized.The experimental data shows that the maximum efficiency of rail transit operation data processing obtained by using the design system is 18.8kb/s,and the accuracy of rail transit monitoring results is 100%,which fully proves that the monitoring performance of the design system is better.
