Research of Integrated Simulation Testing System for Train Autonomous Circumambulation System

Based on the requirements for integrated simulation testing of train autonomous circumambulation system (TACS),particularly in the aspects of supporting environments for system operation, test vectors, and fault injection, this study developed a hardware-in-the-loop simulation (HILS) testing environmental setup, taking into account the characteristics, composition, and fundamental principles of TACS used in urban rail transit, with the core objective of implementing system-wide integrated simulation testing. This environmental setup covers multiple components, including trackside equipment, vehicles, platform screen doors (PSD), integrated supervisory control systems, and communication. It supports the creation of an integrated simulation testing system for specific TACS by connecting to its equipment. The established integrated simulation testing system offers various functions, including integrated testing and verification, as well as fault injection testing, and verification in operational scenarios. The application of this system in actual testing proves its superiority in functionality, design rationality, and effective implementation, capable of providing testing and verification environments with comprehensive functions and a high degree of simulation for TACS.
