Abstract: The present invention provides a five-component marine natural gas hydrate intelligent sensing node, comprising a titanium alloy compartment, an information acquisition unit, an integrated control chip, and a power module; the integrated control chip comprises an intelligent computing unit and a transmission unit; the intelligent computing unit is configured for acquiring quality monitoring indicators of marine natural gas hydrates by feature extraction and transmitting reduced represented features to a monitoring device on the sea surface via the transmission unit. The present invention has overcome problems of impossible timely quality monitoring due to blind acquisition process, promised a controllable undersea node working status, and acquired data are complete without any loss, which doesn't only facilitate nonconventional energy resources such as marine hydrates prospection, and is also of great application prospect and value in oil and gas resources exploration, geological hazards precautions and evaluation.
