Problems solved by technology

[0005] Most of the currently operating Argo buoys use independent observation mode and do not have underwater interactive communication functions. In the existing published patents and literature, no research on the cooperative operation observation method of two or more Argo buoys has been retrieved. There are also few studies on underwater acoustic detection of Argo buoys, which limits the data observation quality and application fields of Argo buoys, and cannot meet the current observation needs of ocean acoustics and environmental parameters.

Embodiment 1

[0063] An Argo buoy such as Figure 1-2 As mentioned above, it includes a pressure-resistant casing 5, which is used to withstand external water pressure to ensure that the internal parts of the Argo buoy are isolated from seawater, and a communication antenna 1 is fixed on the outside of the pressure-resistant casing 5 for transmitting data with satellites. , and obtain positioning information through satellites; the outside of the pressure-resistant shell 5 is also provided with a buoyancy oil bag 3 and a thermo-salinity instrument 11, and the thermo-salinity instrument 11 is used to collect the temperature, salinity and depth environmental parameter information of the ocean water body; A control module 2, an oil storage bag 4, a hydraulic buoyancy adjustment device 6 and a battery 7 are arranged inside the pressure housing 5. The control module 2 is used to send control signals to the hydraulic buoyancy adjustment device 6 and the acoustic transmitter 10, and to process the ...

Embodiment 2

[0068] An Argo buoy, as described in Embodiment 1, the difference is that the hydraulic buoyancy adjusting device 6 includes a linear displacement sensor 13, a damper 14, a one-way valve A15.1, a one-way valve B15.2, a two-way gear pump 16. Electric motor 17, pressure transmitter 19, 2 / 2-way proportional valve A 18.1, 2 / 2-way proportional valve B18.2, 2 / 2-way solenoid valve A 20.1, 2 / 2-way solenoid valve B20.2 and hydraulic Accumulator, hydraulic accumulator includes hydraulic accumulator A 12.2 and hydraulic accumulator B12.1;

[0069] The linear displacement sensor 13 is installed inside the oil storage bag 4 to measure the telescopic displacement Δx of the oil storage bag 4;

[0070] The oil storage bag 4 is connected to the two-way gear pump 16 through the damper 14 and the one-way valve A 15.1. The damper 14 is installed between the oil storage bag 4 and the one-way valve A 15.1 to prevent the oil inlet and outlet of the two-way gear pump 16. When there is a large pressu...

Embodiment 3

[0078] like image 3 , the working process of an Argo buoy is:

[0079] The Argo buoy receives the dive signal sent by the satellite, the control module 2 sets the two-position two-way solenoid valve A 20.1 to the left position, and sends a signal to the motor 17, so that the motor 17 drives the two-way gear pump 16 to rotate counterclockwise, and the hydraulic oil The buoyancy oil bag 3 enters the oil storage bag through the two-position two-way solenoid valve A 20.1 and the two-way gear pump 16, the volume of the buoyancy oil bag 3 is reduced, the drainage volume of the Argo buoy is reduced, and the diving action is performed;

[0080] The Argo buoy is monitored by the thermometer 11 to dive to the desired water depth, and the two-position proportional valve A 18.1 controls the hydraulic accumulator A 12.2 to fill the buoyancy oil bag 3 with oil, so as to expand the buoyancy oil bag 3, and use the temperature and salt depth. Instrument 11 monitors the ascending and descendi...

Abstract

The invention relates to an Argo buoy and a marine acoustics and environmental parameter collaborative observation method based on the Argo buoy, and belongs to the technical field of marine observation. The Argo buoy comprises a hydraulic energy accumulator, an acoustic receiver and an acoustic transmitter. In the invention, the Argo buoys are integrated with the hydraulic energy accumulator and the acoustic transducer, the water depth position can be controlled by adjusting the buoyancy of the Argo buoys, and when two or more Argo buoys hover at different positions, the acoustic transducers carried by the Argo buoys are utilized to carry out mutual underwater acoustic signal transmission, so that acoustic measurement of the water depth positions of different ocean profiles is realized; according to the method, the motion trails of the Argo buoys in the marine environment parameter spring layer area are planned by utilizing the first probing and following action processes of the two Argo buoys, and refined observation in the marine environment parameter spring layer area is realized, so that the data measurement quality and the comprehensive measurement capability of the Argo buoys are improved.

Description

technical field [0001] The invention relates to an Argo buoy and a collaborative observation method of ocean acoustics and environmental parameters based on the Argo buoy, belonging to the technical field of ocean observation. Background technique [0002] The ocean contains all kinds of resources needed for human survival and development, including abundant minerals, oil and gas, and marine life. In order to meet the needs of exploring marine environmental conditions at different depths and dynamically monitoring ocean profile parameters, ocean profile buoys (ie Argo buoys) came into being. The Argo buoy is an ocean observation platform that can autonomously realize up-and-down movement and complete quasi-real-time data monitoring and transmission at the same time. Sensors monitor and record ocean profile parameters. When the Argo buoy travels to the surface, it performs its own positioning and ocean profile data transmission through the satellite system. [0003] At pre...
