The research on early warning and intervention of college students' psychological crisis has become an important issue of concern to the country, society, universities, and college students themselves. Compared to timely intervention and handling of crisis events, it is more important for universities to establish a comprehensive and systematic crisis warning and intervention system. Based on the characteristics of the new media era and the theory of psychological crisis warning and intervention, universities should strengthen the training of student education managers on the use of new media and network information mining technology and make new media an important platform for psychological crisis warning and intervention of college students in the new era.
