Because sealing buoyancy aid 170 may float on the water surface, therefore can make location processor 140 be positioned at the water surface.Therefore, when location processor 140 positions, be conducive to receive and send radio signal, make locating effect better.Be appreciated that in other embodiments, sealing buoyancy aid 170 can omit, and location processor 140 is fixed on floating platform 110.
Further, in the present embodiment, what submarine target monitoring device 100 also comprised positioning suspended platform 110 sinks to the bottom pedestal 180, sinks to the bottom pedestal 180 and is fixedly connected with floating platform 110 by chain cable (figure is mark).During use, sinking to the bottom pedestal 180 can sink under water, and by chain cable, floating platform 110 is fixed on to predetermined depth, and prevents that floating platform 110 from floating.
Alarm processor 150 and signal processor 130 communication connections.And when signal processor 130 judgement targets are potential intrusion target, alarm processor 150 sends caution signal to target.Concrete, alarm processor 150 can send sound wave caution signal, radio warning signal etc., to play the effect of the potential intrusion target of expulsion.
Data transmission unit 160 and signal processor 130 communication connections.When signal processor 130 judgement targets are potential intrusion target, reporting orientation information and positional information.Concrete, data transmission unit 150 can report to locating information and positional information control center's (not shown) of long-range setting.The monitor staff of control center, according to the locating information receiving and positional information, just can obtain position and motion state thereof that potential intrusion target occurs.
Due to standing environment severe occasion ，Ru ocean, the river of being placed in of submarine target monitoring device 100.The variation of external environment likely causes floating platform 110 because rising and falling, rotating, to depart from its predefined position, thereby the result that sonar processor 123 is obtained according to echoed signal is inaccurate.For avoiding occurring this situation, submarine target monitoring device 100 also comprises attitude sensor 190A, depth transducer 190B and sound velocimeter 190C.
Attitude sensor 190A and signal processor 130 communication connections, and be fixed on floating platform 110.Attitude sensor 190A can obtain the status information of floating platform 110, and the status information of obtaining is sent to signal processor 130.This status information comprises with respect to initial position, the deflection angle of floating platform 110 on level, vertical direction.
Depth transducer 190B and signal processor 130 communication connections, and be fixed on floating platform 110.Depth transducer 190B can obtain the depth parameter of floating platform 110, and the depth parameter obtaining is sent to signal processor 130.Depth parameter refers to the floating platform 110 place degree of depth.At different depth, the transmission speed of information of acoustic wave is different.
Sound velocimeter 190C and signal processor 130 communication connections, and be fixed on floating platform 110.Sound velocimeter 190C can obtain the sound velocity gradient parameter of floating platform 110, and the sound velocity gradient parameter of obtaining is sent to signal processor 130 signals.Sound velocity gradient refers in seawater acoustic signals velocity of propagation with the rate of change of the degree of depth.
Processor 130 is proofreaied and correct locating information and characteristic information according to status information, depth parameter and sound velocity gradient parameter.Therefore, can avoid causing monitoring result inaccurate because echoed signal distortion in rugged surroundings or ambient condition change, improve the degree of accuracy of submarine target monitoring device 100.
It is pointed out that in other embodiments, attitude sensor 190A, depth transducer 190B and sound velocimeter 190C can omit, and also can only comprise any one or two kinds in above-mentioned three.
Submarine target monitoring device 100, can make floating platform 110 be suspended in the default degree of depth in underwater during installation.By acoustic array 121, send acoustic signals, and receive by sonar processor 123 echoed signal that detectable signal reflects to form through target, obtain locating information and the characteristic information of target.Signal processor 130 is realized monitoring according to locating information and characteristic information.Because therefore acoustic signals can, need only in the detectable range of target in acoustic signals at water transmission, can survey discovery, and without monitoring according to visual effect, thereby the harmful effect that can avoid environmental factor to cause monitoring effect.Data transmission unit 160 reports the positional information of the locating information of target and submarine target monitoring device, thereby makes to obtain above-mentioned locating information and the timely position of finding whether to exist under water potential intrusion target and potential intrusion target place of positional information monitor staff.Therefore, above-mentioned submarine target monitoring device can be effectively to the monitoring of situation realization under water.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
