The comprehensive simulation training system of fully automatic operation of urban railway aims to solve the problem of lack of safe, efficient and applicable tools for training of single-job practical skills and multi-job collaborative exercise skills in fully automatic operation of urban railway. The system has completely independent intellectual property rights and is based on the simulation of fully automatic operation system GoA3 and GoA4 level operation principles, which can meet the training and assessment needs of personnel in various positions under fully automatic operation scenarios. The fully automatic unmanned urban railway simulation training system mainly consists of core systems such as dispatching operation simulation training system (including vehicle tuning, passenger tuning, line tuning, electric tuning, ring tuning simulation training terminal), station operation simulation training system (including platform and station hall practical training system), train driving simulation training system.
