Safety procedures are the fundamental criteria to ensure the safety of personnel and equipment, and their proficiency and the rigor of the application are crucial. According to the actual existing training technology digital means is relatively backward, intuitive, affect the lack of training depth and effect, this paper to the switch room equipment as the object, based on 3Dmodeling and virtual simulation technology design and developed a can realize safety procedures learning, training of 3D visualization software tools, to solve the difficulty of maintenance training, safety procedures training tools missing problems.
