1. lookout is observed, and carrying out Ren Gong lookout by telescope is tuna seine topmost closely fish finding method at present.Looking at except finding to swim except the shoal of fish by observing water surface color, is also the topmost way finding driftwood.2。Seabird radar scanning, because the bait of tuna and the bait of most seabird have intersection, therefore also has the shoal of fish that swims in the marine site that seabird is numerous usually.Therefore tuna seine ship be substantially all furnished with special S-band or X-band seabird radar, for finding seabird group.3. fishery float, is fixed on buoy on artificial driftwood, passes position back by buoy, thus obtains the position of driftwood, also has now the vertical sonar fishing of the integration of compact of buoy own to visit, can detect the shoal of fish below it, directly shoal of fish information be passed back and fish for ship.
Above in several fish finding mode, it is limited that detection range is observed in lookout, can only detect the fishing feelings near ship.Seabird radar range is comparatively far away, but needs manual operation to wait for.The detection of fishery float fishing feelings can depart from fishing boat and independently carry out, and investigative range is wide, obtains increasing application.
In existing sounding buoy, the most advanced is the satellite buoy visiting function with fishing, and its primary structure comprises waterproof case and internal circuit two parts.Transparent material above shell, can utilize through sunlight, carry out solar electrical energy generation makeup energy.Whole buoy is sealing, can stand sea beat.Internal circuit comprises the fishing spy system, the navigation system be made up of GPS and the data transmission system consisted of satellite communication that form electric power system with solar energy and accumulator, be made up of small-sized vertical sonar.During its work, time opening sonar carries out undersea detection, and passes result of detection affix GPS position information back fishing boat by satellite communication, and such fishing boat just can obtain the fishing feelings information below fishery detector.
This buoy, due to itself with the beam angle that sends of small-sized vertical sonar fishery detector limited, fishing situation condition very among a small circle can only to be detected below it, departs from immediately below it a little, though have fishing feelings also detect less than, easily miss important fishing feelings information.There is detection means single, leak the shortcoming that spy rate is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fishing feelings sniffer based on seabird sound, can expand investigative range.
Inventor of the present utility model finds, because the bait of seabird and tuna has intersection, seabird can be used as the tracing index of tuna fishing feelings, the seabird radar of fishing boat equipment finds fishing feelings by detection seabird.Seabird is normal with spiraling, diving and intensive piping in the process of predation; Do not have the place of bait, the general flying height of seabird is higher, also seldom pipes, and according to this phenomenon, seabird can be utilized to pipe sound as one of fishing feelings detection index.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of fishing feelings sniffer based on seabird sound, comprise buoy body, described buoy body is made up of shell and upper cover, cover on described and be provided with penetrable sound hole, described penetrable sound hole posts waterproof ventilated membrane, inside described waterproof ventilated membrane, sound transducer is installed; Described sound transducer is connected with the circuit board of buoy body interior.
Described circuit board is provided with amplifying circuit, filter circuit and decision circuitry successively.
Described upper cover adopts transparent material to make.
The accumulator for powering for sound transducer and circuit board is also provided with in described buoy body.
Also be provided with solar panel below described upper cover, described solar panel is connected with accumulator.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model utilizes seabird to pipe sound as the means detecting fishing feelings, Miniature Buoy installs additional sound collection and treatment system, realize the fishing feelings detection in buoy surrounding certain distance, thus expand investigative range.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is signal processing flow figure of the present utility model.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment of the present utility model relates to a kind of fishing feelings sniffer based on seabird sound, as shown in Figure 1, comprise buoy body, described buoy body is made up of shell 2 and upper cover 1, described upper cover 1 is provided with penetrable sound hole, described penetrable sound hole posts waterproof ventilated membrane, does Mulching treatment with waterproof ventilated membrane, guarantee that water and moisture can not enter.Sound transducer 3 is installed inside described waterproof ventilated membrane; Described sound transducer 3 is connected with the circuit board 4 of buoy body interior.Described upper cover 1 adopts transparent material to make.The accumulator 6 for powering for sound transducer 3 and circuit board 4 is also provided with in described buoy body.Also be provided with solar panel 5 below described upper cover 1, described solar panel 5 is connected with accumulator 6.
