The Yunda Intelligent Training Solution is based on a training environment constructed with real-line working scenarios, real equipment, real principles, and real operation processes. It combines cutting-edge technologies such as on-site actual scenario modeling, virtual sound field reconstruction, visual correlation analysis, voice and behavior recognition, and artificial intelligence. Centered around the main thread of "one system, two platforms, and N systems", adhering to the principles of "comprehensiveness, forward-lookingness, and practicality", following the basic idea of "professional guidance and progressive ability development", based on relevant theories such as cognitive psychology and constructivism, centering on the requirements of post competency, and supplemented by curriculum systems and evaluation systems, it constructs a complete skill training and assessment system. Starting from the top-level design of three levels including the concept of skill training, the post competency model, and the teaching quality assessment indicator system, it horizontally integrates the training needs of various majors such as "rolling stock, locomotive, track, signaling, power supply, communication, passenger transport, and freight transport". It vertically runs through all aspects from teaching, learning, practicing, examination, to evaluation. Vertically, it continuously extends from routine educational administration management to teaching quality optimization.
