Controller used for marine ranching acoustic taming

Abstract

The invention discloses a controller used for marine ranching acoustic taming. The controller comprises a power supply source, a fish feed throwing controller used for sending bait throwing drive signals to a bait throwing machine, and a taming audio signal generator used for sending taming audio signals to an underwater loudspeaker. The power supply source is provided with a time relay and two power supply output ends, and the time relay can be switched on in the preset work time period and switched off in the preset non-work time period, so that the two power output ends of the power supply source output power supply voltage in the work time period and stop outputting the power supply voltage in the non-work time period. The first power output end of the power supply source is electrically connected with the power supply end of the fish feed throwing controller, and the second power output end of the power supply source is electrically connected with the power supply end of the taming audio signal generator. Timed work of the controller is achieved, it can be guaranteed that the bait throwing machine and the underwater loudspeaker are controlled to be started at the same time, synchronous work of the bait throwing machine and the underwater loudspeaker is achieved, and errors caused by manual operation are avoided.

Description

technical field [0001] The present invention relates to a controller for sound domestication in marine pastures. Background technique [0002] In recent years, with the depletion of marine fishery resources, the development of marine pastures has attracted much attention. The establishment of marine pastures is of great significance to restore and increase marine fishery resources as soon as possible, protect the marine ecological environment, and promote the sustainable development of fisheries. Acoustic domestication technology is one of the technologies to effectively control fish population and achieve pasture management. According to the biological characteristics of pastoral species, the artificially released economic marine organisms are lured into groups by the combination of automatic feeding and sound, and systematic management is carried out in a planned and purposeful manner. In the construction of marine pastures, economic fish species in specific sea areas nee...

AI Technical Summary

Problems solved by technology

[0003] At present, the equipment for sound domestication and sound production mainly uses a combination of signal generators, power amplifiers, and underwater speakers. The equipment is complicated and the operation is complicated.

The equipment must be powered by 220V AC, and the place of use is limited

And it does not have the function of automatic start and stop, and it cannot achieve the effect of simultaneous operation with baiting
