The utility model relates to a virtual interactive emulation training system of 4D based on three -dimensional three -dimensional imaging technique, this system includes: system's host computer is felt to the body, the body is felt system's host computer and is connected with many engineering projectors and a communication module, dynamic sitting, be equipped with in it with the 2nd communication module that a communication module connects, the second newsletter module is connected with drive module and IO module, drive module is connected with smog simulator, photoelectricity simulator, electric shock simulator, sound effect simulator and rainwater simulator, the IO module is connected with proximity switch, RF switch, position distance sensor and switch auxiliary contact. This system restores with the mode of the three -dimensional animation of the four -dimension through reaching relevant accident case to typical project, and simulation true production environment of electric power industry and occurence of failure, developing process make the student that undergoes training have more deep understanding to the danger of incident and the consequence that causes.
