Example Embodiment

[0058] Example 1

[0059] Such as figure 1 As shown, Embodiment 1 of the present invention provides a self-sinking underwater acoustic signal acquisition and storage device, the device includes: a float 1, a hydrophone 2, a metal barrel 3, a magnetic switch 4, a decoupling 5, and a heavy object 6;

[0060] Floating ball 1 is used to increase the buoyancy of the device, and after the device is released, it will float from the water;

[0061] Hydrophone 2 is used to convert sound signals in the water into analog electric signals;

[0062] Set up a lithium battery, a collection and storage board and a hydro-acoustic release mechanism in the metal barrel 3;

[0063] The lithium battery is set in the metal barrel 3 to supply power to the device, and the collection and storage board and the water sound release mechanism are fixed on the lithium battery with a copper pillar;

[0064] The magnetic switch 4 is arranged on the inner wall of the metal barrel 3 and is used to control the switch of ...

Example Embodiment

[0083] Example 2

[0084] Such as Figure 4 As shown, Embodiment 2 of the present invention provides a method for placing and recovering an underwater acoustic signal collection and storage device, including the following steps:

[0085] In the first step, use a magnet to approach the magnetic switch 4, the red power indicator will light up, and the device will be powered on;

[0086] In the second step, the GPS timing module 16 is powered on, and then it starts to synchronize the clock. If the GPS timing module 16 is powered off within ten minutes, it means that the GPS clock is successfully synchronized. The current time is written into the SD card 15 to start collecting water acoustic signals. The time collection indicator flashes once every twenty seconds.

[0087] The third step is to put the device into the sea for long-term data collection and storage;

[0088] The fourth step is to use the deck machine to call out the release code, the release light on the device will light up...

Abstract

The invention discloses a self-sinking self-floating type underwater sound signal acquisition and storage device, a putting method and a recycling method. The device comprises a supporting rod, a floating ball (1) for increasing floating force to the device, a hydrophone (2) used for acquiring an underwater sound signal and a metal barrel (3), wherein the floating ball (1) is arranged on the top of the supporting rod, the metal barrel (3) is arranged on the bottom of the supporting rod, the hydrophone (2) is fixedly arranged on the side wall of the supporting rod, the bottom of the metal barrel (3) is equipped with a detacher (5); the detacher (5) is connected to a heavy object (6); a storage plate and an underwater sound release mechanism are arranged in the metal barrel (3); the storageplate is used for processing an underwater sound signal received by the hydrophone (2), and storing the processed underwater sound signal in the form of a data file according to the time information;and the underwater sound release mechanism is used for releasing the heavy object (6) by controlling the state of the detacher (5), so that the whole device floats out of a sea surface under driving of the floating ball (1), and device recycling is realized through positioning information.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic measurement, in particular to a self-sinking and floating underwater acoustic signal acquisition and storage device, and a feeding and recycling method. Background technique [0002] As we all know, the propagation attenuation of sound in water is the smallest, the propagation performance is the best, and it can realize long-distance transmission. It is currently the most important information carrier for studying underwater targets and marine environmental noise. Therefore, underwater acoustic measurement technology has been paid more and more attention by people. The underwater acoustic signal acquisition and recording device can be used to monitor the noise of the marine environment and study marine life, etc. However, the current underwater acoustic signal acquisition equipment generally has the disadvantages of small data storage capacity, high power consumption, and cumbersome mo...
