Ocean information detection cluster system and detection method

Abstract

The invention belongs to the technical field of ocean information detection, and discloses an ocean information detection cluster system and a detection method. The system is provided with a pluralityof underwater instrument collection units fixed on a rope. The system is also provided with a plurality of overwater wireless communication responders, arranged on the special workboat or dragged orfloated on the water surface; a controllable computer, in wireless connection with the underwater instrument acquisition unit and the overwater wireless communication transponder. The state of the underwater instrument acquisition unit is sent to the overwater wireless communication transponder on the sea surface in a coding form. The controllable computer is connected to a specified working platform through a network to realize remote control of the ocean information detection cluster system. The defects that an existing seabed underwater instrument collection unit cannot achieve real-time communication and data transmission on the seabed, the working state of the seabed underwater instrument collection unit on the seabed cannot be known, and collected data cannot be monitored in real time are overcome. And the manufacturing cost is reduced and the time precision is improved by using a real-time time service technology.

Description

technical field [0001] The invention belongs to the technical field of marine information detection, and in particular relates to a marine geophysical information detection cluster system and a detection method. Background technique [0002] At present: the existing marine geophysical information detection technology is mainly the seabed artificial seismic exploration technology, which is mainly composed of seismic sources and acquisition instruments. Most submarine seismic exploration technologies use non-explosive (air guns, steam guns, electric sparks, etc.) artificial seismic sources to excite. The seismic sources are generally sunk to a certain depth under the set sea surface, and are composed of a dedicated marine source system. Acquisition instruments are generally placed on the seabed to receive signals generated by artificial seismic sources, reflected and refracted by the sea surface, water body, seabed, and deep underground, and the collected signals are subsequen...

AI Technical Summary

Problems solved by technology

[0005] Because all acquisition units must be connected by cables, data transmission and power supply, the OBC system restricts the application of technology, and has the following defects: (1) The expansion of acquisition units is limited, which is not suitable for high-density acquisition at sea; (2) Submarine deployment requirements High, requiring special deck equipment and professional operators; (3) Once the cable fails, it is difficult to repair on site, resulting in shutdown; (4) The structure of the equipment has a certain impact on the collected data

[0008] First, the underwater node instrument itself cannot be positioned, and additional positioning equipment needs to be configured, which brings difficulties to construction and increases costs

[0009] Second, it is impossible to monitor the working status of underwater node instruments in real time, and it is impossible to transmit relevant data collected by underwater node instruments in real time

[0010] Third, the underwater node instrument has been on the seabed for a long time, and the drift of its timing system brings errors to the system, affecting the quality of collection, and it is impossible to time the underwater node instrument working on the seabed again for time correction
