Based on the complex information system, this paper studies the education mode of the industrial design major in higher vocational colleges, and designs a background processing and online integration and reconstruction platform for the guidance network of the higher vocational industrial design major. Firstly, it analyzes the characteristics of the complex information system interface with Kernal as the frame, studies the application of the industrial design specialty in the complex information system interface design in higher vocational education, and implements the arrangement, topic selection, implementation principle, implementation process, Specific practice has been carried out in terms of assessment requirements and so on. The practice data is entered and processed based on MongleDB, and the online data is integrated and reconstructed using C++ modeling.
