Wireless remote control fish-finding method and system

Abstract

The invention provides a wireless remote control fish-finding method and system. The wireless remote control fish-finding method comprises the steps that S1, an unmanned detecting subsystem is arranged on a water surface remote control carrier, and a ship-borne control subsystem is arranged on a ship body; S2, the ship-borne control subsystem controls the moving direction and speed of the water surface remote control carrier; S3, a fish-finding signal processing mechanism generates fish-finding electric signals to be transmitted to a fish-finding sensor mechanism; S4, the fish-finding sensor mechanism converts the fish-finding electric signals into submarine sound signals to be transmitted outwards, and submarine sound echo signals are received; S5, the fish-finding sensor mechanism converts the submarine sound echo signals into feedback electric signals to be transmitted to the fish-finding signal processing mechanism; S6, the fish-finding signal processing mechanism transmits detecting result data to the ship-borne control subsystem; S7, the ship-borne control subsystem displays the detecting result data; and S8, if operation is not finished, the step 2 is returned. According tothe wireless remote control fish-finding method and system, the fish-finding distance can be expanded greatly, the property of a fish-finding meter can be improved, and the fish-finding efficiency inmarine fishery catching can be improved.

Description

technical field [0001] The invention relates to the field of fish detection methods and systems, in particular to a wireless remote control fish detection method and system. Background technique [0002] The marine fishery fishing process mainly relies on fishing aids to complete the detection and tracking of underwater fish schools. It is a unique equipment for fishing boats. Its main function is to find fish schools and monitor the net situation. Fish detection equipment mainly includes fish detection equipment, network information (detection) equipment, etc. Since electromagnetic waves attenuate quickly in water, the main detection method of fish detection instruments is sound waves. In the early 1950s, Norway began to build sonar specially used for fish detection, thus giving birth to the earliest commercial fish finder. By the 1960s, fish finders had become an indispensable fishing aid in ocean fishing. After the 1990s, digital technology was widely used in fish find...

AI Technical Summary

Problems solved by technology

At present, the traditional fish detection method is generally implemented by using a fishing boat equipped with a fish finder, but the fish finder will be limited by the size, transmission power, water depth, reverberation and noise level during the detection process, especially the noise of the fishing boat engine. The detection distance of the on-board fish finder has a great influence, and its range of action is within a radius of 5 kilometers from the fishing boat; the fish detection distance is limited, and the fish detection efficiency is low
