Aiming at the current status of submarine equipment software, considering it with engineering practice, and making use of the software modularization ideas, this paper brings forward submarine command and control software model and software hierarchical structures based on component modules.

In allusion to the characteristic of student s weakly manipulative ability in general,the experimental platform of computer cognition provides all transparent,structured and modular components,allow students to see the internal structure of the computer and form the computer system and its own local area network with their own hands.
