Abstract: In combination with the actual situation of power generation enterprises, a five dimensional internet plus safety education and training system mechanism is proposed, which integrates induction training,qualification examination, continuing education, self-study training and simulation experience. Based on the dual prevention mechanism of risk grading control and hidden danger investigation and governance, and supported by big data management, a basic database of safety education and training is established, which constitutes the specific safety education and training contents for the staff, solves the problems such as incomplete safety education and training system, inaccurate content, poor effectiveness, insufficient duration, inadequate supervision,and incomplete records, and improves the effectiveness of safety education and training.
