The embodiment of the application provides a diving interaction system and interaction method. A mother submersible is connected with at least one subsidiary submersible; when the mother submersible is utilized to drive the subsidiary submersible to reach a preset position range in an operation sea area, the operation permission of a virtual cockpit is given through a control center, and the mother submersible and the subsidiary submersible are controlled to be detached from each other, so that the virtual cockpit can operate and control the subsidiary submersible; and the subsidiary submersible can feed back detected information to the virtual cockpit. Through the arrangement, simulated driving is realized by virtue of the detachable connection manner between the mother submersible and the subsidiary submersible and by virtue of the virtual cockpit, and the interaction demand of operating submersibles by non-professionals can be realized under the circumstances of avoiding damage to equipment and environment and ensuring the personal safety of operators.
