Description

HIGH-PRECISION SUBMERSIBLE BUOY ARRAY SYSTEM FOR
REALIZING MARINE DATA AREA MONITORING
TECHNICAL FIELD
[01] The present invention relates to the technical field of marine observation equipment, and in particular, to a high-precision submersible buoy array system for realizing marine data area monitoring.
BACKGROUND ART
[02] From the existing submersible buoy system and the latest technology, it is not difficult to see that a real-time submersible buoy transmission technology has been improved, the development of a marine monitoring technology in China has achieved brilliant results, and China has successfully overcome a worldwide marine observation problem "long-time real-time submersible buoy data transmission". It is the first time to realize long-term stable real-time transmission of deep sea data and application sharing.
The publication of "Western Pacific Deep Sea Submersible Data System" fills the gaps in China. The problem that data can only be collected once a year in conventional submersible buoy observation is changed, and a view mode of deep sea data changes from "video replay" to "live broadcast". "Real-time data transmission will provide an important technical support for marine environment and global climate research, and data transmitted back in real time will improve the precision of marine climate and environmental prediction." The worldwide problem of real-time transmission of deep sea submersible buoy observation data is solved. However, there are still two problems in the field of submersible buoys: 1. Instruments for detecting different water depths through a submersible buoy in the field of deep sea marine monitoring are basically fixed nowadays, that is to say, ADCP and TD are generally arranged at a water depth of about 300-500 meters, CTD and RCM are generally arranged at a water depth of about 800- 1000 meters, and an inductively coupled temperature-salinity chain is mounted at about 50-100 meters underwater for monitoring profile measurement of the seawater temperature, salinity, circulation, echo intensity, and other marine environmental parameters of each section of water depth. It can be seen therefrom that the above monitoring equipment can only collect data for a specific depth of seawater information after completion of deployment. At present, since the total length of the submersible buoy is thousands of meters or even several thousands of meters, it cannot be adjusted arbitrarily once the deployment is completed. Therefore, limited data can be obtained, and marine data cannot be collected at different water depths. Moreover, because the system is deployed underwater and a plurality of valuable measuring instruments are integrated, whether to achieve reliable retraction becomes the primary problem to be considered when deploying a submersible buoy system. The conventional method uses submersible buoy positioning, which can ensure the successful retraction of the submersible buoy system. However, due to the complex and harsh seabed environment, there are many uncertain factors. In the process of retraction after positioning, a plurality of floating balls mounted on a cable will float the whole monitoring chain of submersible buoys. Once winding occurs, not only the difficulty of salvage retraction is increased, but also measuring instruments on the cable are easily damaged. At present, an acoustic response releaser is used to retract the submersible buoys, but components such as an anchor chain, a gravity anchor and a grab anchor connected below the releaser cannot be retracted, which causes waste. 2. The current submersible buoy system can only collect profile data of a small sea area, and parameters thus obtained can only be used for evaluating a sea condition of the small sea area. How to perform synchronous data monitoring and collection on a large sea area is now a problem to be solved urgently by a person skilled in the art.
SUMMARY
[03] In view of the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a high-precision submersible buoy array system for realizing marine data area monitoring, which is capable of simultaneously collecting the whole marine data of a sea area while ensuring real-time transmission of deep sea data and ensuring the accuracy of the real-time transmission, realizing profile measurement of marine environmental parameters at different depths, and effectively protecting carried measuring instruments during retraction.
[04] In order to solve the above technical problem, the technical solution adopted by the present invention is as follows. A high-precision submersible buoy array system for realizing marine data area monitoring includes a main submersible buoy, a plurality of auxiliary submersible buoys deployed around the main submersible buoy to form a area to be monitored, and a surface buoy system in wired or wireless connection with the main submersible buoy for receiving profile measurement data received by the underwater main submersible buoy in real time and uploading the data to a bidirectional communication satellite. The bidirectional communication satellite feeds back the acquired real-time measurement data to a land laboratory. The main submersible buoy includes a synchronizing signal sending unit for simultaneously sending a start signal to each auxiliary submersible buoy for a detection operation, a receiving unit for receiving monitoring data returned by each auxiliary submersible buoy, and a data storage unit and a real-time data transmission unit for storing the profile measurement data of each auxiliary submersible buoy and sending the data to the surface buoy system. Each auxiliary submersible buoy is provided with a data sending unit for sending the real-time monitoring data to the main submersible buoy. The main submersible buoy and the auxiliary submersible buoys further include:

Each auxiliary submersible buoy 45 is provided with a data sending unit for sending the real-time monitoring data to the main submersible buoy 43.
The main submersible buoy 43 and the auxiliary submersible buoys 45 further include a vertically arranged plastic-coated steel cable 4. A sub-floating body 5 for providing buoyancy is arranged at a top end of the plastic-coated steel cable 4. A temperature- salinity chain 6 composed of a plurality of temperature-salinity sensors arranged sequentially is mounted on the plastic-coated steel cable 4 below the sub-floating body 5. An anchor mooring unit 7 and a release unit 8 for retracting the system are arranged at a bottom end of the plastic-coated steel cable 4. The anchor mooring unit 7 includes an anchor chain 9 connected to the bottom end of the plastic-coated steel cable 4. A gravity anchor 10 is connected to a tail end of the anchor chain 9 through a shackle. An anchor cable 12 with a grab anchor 11 at the tail end is connected to the shackle. The release unit 8 includes an acoustic response releaser 13 connected between the anchor chain 9 and the plastic-coated steel cable 4. A top end of the anchor chain 9 is connected to the acoustic response releaser 13 through a connecting buckle. A main floating body 14 1s arranged on the plastic-coated steel cable 4 below the sub-floating body 5 for carrying a shallow water measuring instrument. The main floating body 14 carries two acoustic Doppler current profilers respectively driven up and down, a temperature-depth meter and a temperature meter. The main floating body 14 includes a data storage and sending unit for storing profile measurement data collected by each measuring instrument and sending the data to the surface buoy system 2.
[20] A plurality of glass floating balls 15 are connected between the main floating body 14 and the release unit 8 for providing a balancing force to the plastic-coated steel cable 4. A frame body 16 arranged between the main floating body 14 and the release unit 8 for carrying a deep water measuring instrument is further included. The deep water measuring instrument carried on the frame body 16 in the present invention includes a current meter 17 and a conductivity-temperature-depth meter 18. The frame body 16 is provided with a lifting adjusting mechanism 19 for driving each deep water measuring instrument to move up and down along the plastic-coated steel cable 4 to measure profile measurement data at different water depths. The lifting adjusting mechanism 19 includes a housing 20 connected to the frame body 16. A roller shaft 21 which allows the plastic- coated steel cable 4 to be wound is transversely arranged in the housing 20. Openings 22 which allow an upper plastic-coated steel cable 41 and a lower plastic-coated steel cable 42 to enter and protrude are respectively provided on upper and lower parts of the housing 20. A servomotor 23 drives the rotation of the roller shaft 21 to move up to retract the upper plastic-coated steel cable 41 and release the lower plastic-coated steel cable 42 or move down to release the upper plastic-coated steel cable 41 and retract the lower plastic-coated steel cable 42. An encoder for receiving a signal, and a controller are arranged on the servomotor 23. The controller sends a signal to the encoder through a pre-set upper limit and lower limit of the stroke. After receiving the signal, the encoder drives the servomotor 23 to move up or down along the plastic-coated steel cable 4.
When the upper limit or lower limit of the stroke is reached, the controller sends a signal for driving the servomotor 23 to stop and return to the encoder. The encoder drives the servomotor 23 to reverse and return to a starting point of moving up or down. The plastic-coated steel cable 4 enters the housing 20 through the openings 22 on the upper and lower parts of the housing 20 and is wound on the roller shaft 21 clockwise or anticlockwise. In the present invention, power may be supplied to the servomotor 23 in the form of a storage battery 24, and the surface buoy system 2 may be provided with a solar panel for continuously supplying power to the storage battery 24, or a storage battery 24 of sufficient charge is adopted to meet power supply requirements for the required monitoring time.
