Research on Test Architecture for Full Automatic Operation of Urban Rail Transit Based on Cloud Platform and Digital Twin Technology

With the rapid development and application of Unattended Train Operation (UTO) system in the field of urban rail transit, the traditional Communication Based Train Control (CBTC) signal system test platform has become inadequate to meet the requirements of testing [1], training and emergency drills for complex and changeable Fully Automated Operation (FAO) [2] scenarios. This paper proposes a Test architecture based on cloud platform and digital twin [3] technology. Compared with the traditional CBTC test platform, it comprehensively improves the performance of the platform, builds complex and changeable test scenarios unique to the FAO environment, and provides 3D rendering and simulation [4] closer to the real operation environment. On the premise of meeting the testing requirements of the FAO environment, it can also provide services for operation training and emergency drills.
