Problems solved by technology

The disadvantage of this working mode is that the layout is cumbersome, especially when the cable is not a load-bearing cable, it is necessary to prepare a steel cable for load-bearing, and it is easy to entangle and wear between the cable and the steel cable
In addition, in the current research on the fluctuation of the acoustic field of ocean acoustics, a sound source device that can emit continuously at a fixed point is needed, and the current sound source device does not support this working method

Embodiment Construction

[0014] The present invention will be described in detail below in combination with specific embodiments.

[0015] The invention includes a rechargeable battery, a power amplifier, a control module, a watertight cabin, a pressure sensor, a transducer and upper computer software. The control module is connected to the power amplifier, the power amplifier is connected to the transducer, the pressure sensor is connected to the control module, the computer installed with the host computer software is connected to the control module through USB, and the rechargeable battery supplies power for the whole system. The circuit part of the system is located in the watertight cabin, and the transducer and the watertight cabin are connected through watertight joints. The entire system is made of watertight technology to meet the pressure resistance requirements. When working in the lifting mode, or deploying buoys and submersible buoys, just remove the shroud and tail fin. Download the wav...

Abstract

The invention discloses a self-contained sound source which comprises a rechargeable battery, a power amplifier, a control module, a watertight cabin, a pressure sensor, an energy converter and an upper computer. The control module is connected with the upper computer through a USB interface, upper computer software realizes functions of system time checking, task table establishing and signal waveform downloading and further realizes function of setting parameters like working depth interval range and depth sampling interval, a depth sensor is connected into the controller to realize real-time recording of depth information and can realize a function of stopping signal emitting to protect the energy converter after equipment emerges from water according to depth value and depth working interval range. The self-contained sound source has the advantages that the self-contained sound source works in a dipping or dragging mode, only a dragging steel cable is needed, and extra power supplyis not needed, so that sound source emitting work is simplified greatly, and a system works more reliably and simply.

Description

technical field [0001] The invention belongs to the technical field of underwater acoustic signal transmission and relates to a self-contained sound source. Background technique [0002] Artificial regular sound sources are often used in marine acoustic surveys and researches. The general working mode is hanging or towing. It is characterized in that the signal transmitter and power amplifier are located on the ship, and the amplified signal is transmitted to the transducer through the cable. The disadvantage of this working mode is that the layout is cumbersome, especially when the cable is not a load-bearing cable, it is also necessary to prepare a steel cable for load-bearing, and it is easy to entangle and wear between the cable and the steel cable. In addition, in the current research on the fluctuation of the acoustic field of ocean acoustics, a sound source device that can emit continuously at fixed points is needed, and the current sound source device does not suppor...
