And Training

A simulation training system of multi-effect seawater desalination is helpful for research and training. A method of organizing the virtual space and models into a hierarchy tree was proposed, according to their topology relationship. The simulation model of seawater desalination plant was given, and the PID control system was designed. According to different kinds of operation modes, the meaning of gestures in different scene context was analyzed. A context-sensitive fast algorithm was proposed to accelerate the collision detection. A simulation training system of multi-effect seawater desalination is successfully realized and applied in worker’s training.
