Problems solved by technology

Otherwise, once an accident occurs, the fishing net will sink into the seabed, which will not only cause huge economic losses, but also cause serious damage to the ecological environment.
In addition, the weather on the sea surface is erratic. Sometimes ships encounter storms and abandon their fishing nets and evacuate urgently. It is very difficult to find the target again afterwards.

Embodiment Construction

[0020] figure 1 Middle: 23 is a fishing boat, 24 is a fishing net, 25 is a buoy, 26 is a lead pendant, 27 is a cable, and 30 is a sonar launcher. The system consists of a host transmitter and multiple sonobuoys with receivers and mechanical actuators. The host transmitter is placed on the fishing boat 23 and is operated by fishery personnel. The sonar buoy 25 sinks into tens of meters depth of water together with the fishing gear when the net is lowered, so as to avoid the interference of wind and waves on the water surface and passing ships. When it is necessary to hoist the net, you only need to control the main engine to emit sonar remote control coded signals within a few kilometers from the extension, and the sonar receiver of the selected extension will output the switch signal to drive the mechanical actuator, and open the lock to make the sonar buoy float from the water. The underwater target can be found along the rope attached to the buoy to carry out the net lifti...

Abstract

An unlocking system control remotely by sonar for marine fishing features use of sonar technique to transmit encoded signals for remote control to large fishing facilities and is composed of host and multiple sonar buoys. Said host consists of single-chip microprocessor, hand-held remote control signal encoder, pulse power amplifier, sonar emitting transducer and power supply. Said sonar buoy comprises the signal decoder composed of sonar signal sensor, small signal amplifier, frequency converter, filtering shaper and single-chip microprocessor, power driven and mechanical unlocking mechanism.

Description

technical field [0001] The invention relates to a sonar remote control unlocking system for ocean fishing, which belongs to the field of underwater acoustic electronic remote control equipment. Background technique [0002] In pelagic deep sea fishing operations, it is often necessary to sink fishing equipment such as fishing nets to the bottom of the sea for several days. Then set buoys on the water surface for positioning, so as to be easy to find. In order to prevent buoys, fishing gear from being stolen or ropes being entangled and damaged by passing ships, fishing boats need to wait. Otherwise, once an accident occurs, the fishing net will sink into the seabed, which will not only cause huge economic losses, but also cause serious damage to the ecological environment. In addition, the weather on the sea surface is erratic. Sometimes ships abandon their fishing nets and evacuate urgently in case of storms. It is very difficult to find the target again afterwards.
