With the intensification of social competition, the mental health issues of college students are becoming increasingly prominent. It is imperative to establish a dedicated university mental health education online platform. This paper proposes the design and development of a "Internet+" university mental health education platform, which includes four modules: Information, Communication, Counseling, and Interaction. It provides online education, communication, and counseling services to enhance the psychological well-being of college students. The platform adopts a B/S architecture, PHP+MySQL+Vue.js technology stack, and constructs iOS/Android applications to enable mobile internet access. The implementation process emphasizes modular development and comprehensive testing. This research aims to explore a new model of web-based mental health education for college students. The platform has broad application prospects in promoting the psychological development of college students, as it offers extensive coverage, rich resources, timely communication, and professional, continuous, and personalized services.
