The integrated operation simulation training system for urban rail transit can be used to train and assess the post skills of personnel in various majors and positions in urban rail transit. Based on real principles, the system maximally restores the actual situation of the operation site, and can meet the training and assessment needs of all majors and positions in aspects such as standard one-time operations, abnormal fault handling, multi-trade emergency drills, and equipment maintenance. For train operation scenarios, the system adopts the "Key Technologies of Virtual Operation Environment for Urban Rail Trains", which won the first prize of Sichuan Provincial Science and Technology Progress Award, to realistically restore the complex operation environment of "human-train-line-network". Based on cutting-edge technologies such as scenario modeling, virtual sound field reconstruction, and visualized correlation analysis, it creates a new-generation comprehensive platform for multi-trade joint drills, providing a digital, automated, and intelligent comprehensive platform for personnel training, equipment design, and scheme verification, thus improving the quality and efficiency of relevant work.
