With the rapid development of the Internet technology in education,traditional vocational education practical training methods have been unable to effectively meet current teaching needs due to fac-tors such as limited space,high costs,and lagging technological development. By constructing an online practical training platform based on virtual simulation technology and utilizing artificial intelligence to achieve closed-loop tracking of online practice and offline learning,the interactive and visualized full-process practical teaching is achieved to scientific and effective data support for students' professional posi-tioning and practical teaching quality research. Practice has shown that the online practical training platform based on virtual simulation technology can effectively improve the efficiency and level of vocational educa-tion practical training,optimize the matching degree between students' career development and local eco-nomic development needs,and provide data-driven decision support for cultivating high-quality applied ta-lents.
