In-situ long-term real-time observation system and method for deep-sea engineering geological environment

Abstract

The invention relates to an in-situ long-term real-time observation system and method for the deep-sea engineering geological environment. The in-situ long-term real-time observation system comprisesobservation instruments, a mat-supported carrying platform, an observation data relay and transmission buoy system, a remote observation data management server, a client and a matched release and recovery method. The observation instruments and the carrying platform are laid and recycled through a hydraulic penetration mechanism, an acoustic releaser and an underwater robot. The observation instruments and the mat-supported carrying platform are integrated with seawater batteries, and relay and transmission buoys are integrated with solar batteries, thereby realizing self power supply of a submarine observation platform and a sea surface data relay system. The remote observation data management server and the client can query and download the observation data and change parameter settings.The in-situ long-term real-time observation system overcomes the defects that a submarine observation network is long in construction time and great in capital investment and that the common mat-supported observation station cannot be powered by itself or perform real-time data transmission, realizes in-situ, long-term and real-time observation for the deep-sea engineering geological environmentand can be applied to projects such as long-term monitoring for the deep-sea hydrate mining environment and the like.

Description

technical field [0001] The invention belongs to the technical field of marine observation, and in particular relates to an in-situ long-term real-time observation system and method for deep-sea engineering geological environment. Background technique [0002] Deep-sea in-situ, long-term, real-time observation system is an important means of marine scientific research. The lack of effective in-situ, long-term and real-time observation means restricts the in-depth understanding of the mechanism of marine dynamic processes, and has also become a bottleneck for effective prediction and prevention of marine disasters. At present, numerical simulation and repeated survey and sampling methods are mostly used in the research on the change of geological environment in marine engineering, which urgently needs the support and verification of long-term ocean observation data. [0003] At present, the land engineering geological environment observation technology has been basically perf...

AI Technical Summary

Problems solved by technology

The construction period of the submarine observation network is long, it costs a lot of money, it is difficult to manage and maintain, and it has low flexibility

Ordinary bottom-mounted / penetrated observation platforms are mostly unable to integrate self-generated power supply systems, cannot meet long-term observation needs, and cannot realize real-time communication and remote control

The current penetrating observation platform mostly adopts the gravity penetrating method to penetrate the probe rod into the sediment by its own gravity, which cannot achieve effective penetrating into the hard bottom sea area

For the base / penetrating observation platform, my country still does not have the technology and equipment with independent intellectual property rights to realize in-situ, long-term and real-time observation of the seabed
