AR-based electric power facility operation training simulation systemTechnical Field
The invention relates to the technical field of electric power skill training, in particular to an AR-based electric power facility operation training simulation system.
Background
The rapid development of high technologies such as computer technology, multimedia technology, network technology and data construction technology has a great influence on the learning, living and working modes of people, and the innovation of teaching systems such as teaching environment, teaching method and review mode is initiated, so that training and teaching innovation based on the technologies has become a great trend of the development of 21 st century teaching systems.
The increasing scale of power systems requires ever increasing levels of business and skill levels for power operators to accommodate the increasingly complex safe operation of power systems. In reality, due to various reasons such as higher investment cost and higher maintenance cost of the power equipment, many new staff training cannot be performed by using real objects, and enterprises are less likely to use the equipment in production for training due to the consideration of safety factors. Therefore, most of electric staff training in China is still mainly performed by teaching and examination, and the training mode has a plurality of problems.
First, the personal quality of trained personnel is different, and the training content is not targeted. The same training mode cannot be adopted in the training process due to the knowledge background, business foundation and understanding and acceptance of new knowledge and new skills of the staff of the power enterprises. For example, some old staff only have the middle school and the following level, but the actual operation experience of the old staff is quite rich; while young employees are almost the family, even some are high-grade students with the college and doctor, they have very solid theoretical basis, and if the same teaching mode is adopted for all employees, the training of the employees cannot achieve ideal effects.
Secondly, trained personnel can hardly go to the site, and practical operation opportunities are less. For a long time, because the cost of the running equipment of the power system is very high, and the power enterprises consider factors such as equipment running safety and personnel safety of staff, the chance that trained staff takes part in on-site training is relatively small, the staff cannot feel actual operation in person, and perceptual knowledge is lacking.
Third, the training is not lively enough and the training form is single and boring. Most of the staff training of electric power enterprises in China still adopts a mode of backing 'safety rule' and checking 'safety rule', and some of the staff training adopts a mode of reading electric power safety accidents and analyzing the reasons of the accidents. Whether the safety accident is analyzed by the 'safety rule', the mode that a teacher speaks to listen to the student is adopted, the novelty and the attraction are lacking, and the trained personnel cannot be impressive.
In order to guide and standardize pre-post training and skill assessment system of new advanced electric power maintenance and marketing personnel and optimize training effect, in recent years, policy files for promoting deep application of virtual reality in education and teaching are frequently released, and along with diversification of virtual reality hardware equipment and enrichment of teaching resources, virtual reality gradually becomes a necessary development trend of future audio-visual education in education and teaching.
