Digital Twins for Daily Operation Management of Railway Station

Station daily operation management is an essential task in the railway industry. To enhance the efficiency of this process, we propose a digital twins four-dimensional model for daily station operations (DTSDO) in this study. The DTSDO model consists of four distinct components: Passenger Station Physical Entity (PSPE), Passenger Station Virtual Entity (PSVE), Digital Twins Connections (DTCS), and Daily Operation Twins Services (DOTS). The DTSDO is driven by the fundamental data of passengers and trains, and it uses the eEPCD to link and control the Six essential production elements within the station based on a time sequence. The communication between the PSPE and PSVE is established via the HTTP protocol. The DOTS accurately portrays the virtual representation of the reality passenger station. Furthermore, we have validated the DTSDO model using Qinghe station as a specific case study. We created a one-to-one model of the station and tested its comprehensive functionalities.
