Design of Real-time Joint Control Platform for Subway Train Operation Information Driven Based on Multi-source Data
In order to create the connection between the on-board train system and the ground information system,realize the in-stant interaction of information,and ensure the safe and stable operation of subway trains,a real-time joint control platform of subway train operation information driven based on multi-source data is designed.The platform consists of the on-board system and the ground system two parts.The on-board data management equipment of the on-board system uses the information serv-ice network to obtain the data of the subway train system and equipment from the traction,braking and other systems,and sends the data to the big data cluster of the ground system through wireless communication technology.The big data cluster in-tegrates and collects the on-board operation data information through the combination empowerment method.Moreover,through the fusion data consistency test,the subjective preference is eliminated to ensure the objectivity of multi-source data fu-sion.The digital application terminal realizes multiple joint control functions by using the results of multi-source data fusion,and the fault diagnosis module combines empirical mode decomposition and FCM clustering to realize the fault classification and diagnosis of subway train operation.The experimental results show that the designed platform can collect subway train opera-tion information,and accurately judge subway train faults by decomposing the obtained IMF component characteristics,so as to ensure the smooth running of subway trains and the personal safety of passengers.
