High-accuracy submersible buoy system for marine data region monitoring

Abstract

The invention discloses a high-accuracy submersible buoy system for marine data region monitoring. The high-accuracy submersible buoy system comprises a main submersible buoy and a plurality of auxiliary submersible buoys. A to-be-monitored region is formed around the main submersible buoy by the auxiliary submersible buoys. Profile survey data received by the main submersible buoy underwater arereceived in real time, and are uploaded to a water surface buoy system of a bidirectional communication satellite. The bidirectional communication satellite feeds back the survey data to a land lab inreal time. The main submersible buoy comprises a synchronizing signal sending unit, a receiving unit, a data storage unit and a real-time data transmission unit. The synchronizing signal sending unitis used for sending startup signs to the auxiliary submersible buoys at the same time to perform survey. The receiving unit is used for receiving monitoring data returned by the auxiliary submersiblebuoys. The data storage unit is used for storing the profile survey data of the auxiliary submersible buoys and sending the data to the water surface buoy system. A data sending unit for sending real-time monitoring data to the main submersible buoy is arranged on each auxiliary submersible buoy. The high-accuracy submersible buoy system has the advantages that the whole marine data of a sea region can be collected simultaneously, and can evaluate conditions of water bodies in the sea region more accurately as compared with conventional local marine profile data.

Description

technical field [0001] The invention relates to the technical field of marine observation equipment, in particular to a high-precision submarine array system for realizing regional monitoring of marine data. Background technique [0002] Submersible buoy technology was used and developed by some marine developed countries in the 1960s; a system for long-term observation of marine environmental elements moored below the sea surface, and an acoustic release device can be recovered from the sea surface according to instructions. The buoy and submersible buoy system is an important technical equipment for marine environmental investigation. It has the characteristics of unattended long-term, continuous, synchronous and automatic comprehensive monitoring of various elements of marine hydrology and meteorology under harsh marine environmental conditions. The spatial and temporal expansion of marine observation shore stations, survey ships and survey aircraft is an important means ...

Problems solved by technology

However, there are still two problems in the field of submarine marks: 1. In the field of deep sea ocean monitoring, the instruments for detecting different water depths through submerged marks are basically fixed, that is to say, ADCP and TD are generally set at a water depth of about 300-500 meters, and CTD The RCM is generally set at a water depth of about 800-1000 meters, and an inductively coupled temperature-salt chain is installed about 50-100 meters below the water surface to monitor seawater temperature, salinity, circulation, echo intensity and other marine environmental parameters at each water depth. Profile measurement, it can be seen that the above-mentioned monitoring equipment can only collect data for seawater information at a specific depth after the deployment is completed. At present, the submersible buoy cannot be adjusted arbitrarily once the deployment is completed due to the total length of thousands of meters or even several kilometers.

At present, the acoustic response releaser is used to realize the recovery of the submersible buoy, but the anchor chain, gravity anchor, grasping anchor and other components connected below the releaser cannot be recovered, resulting in waste
