The general topography under water is complicated, the sound wave that sends returns and receives and to interfere with when board department of receiving sound, the sound wave direction still can change, and it is limited to receive the sound board area, unable maximize receives the sound wave that returns, the effect of formation of image also can be discounted greatly so, after the installation of the sound board of so existing, still need carry out artifical debugging when using, generally need the old-fashioned operating personnel of experience to carry out artifical the regulation, in order to reach best receiving angle, the control degree of difficulty is big like this, the difficulty of handing, the accuracy is low, the imaging effect is poor.
Example one
As shown in fig. 1, which is only one embodiment of the present invention, the present invention provides a sonar sound board control method, including the steps of:
s1: dividing the sound receiving board into at least one sound receiving unit, and numbering the sound receiving units according to the arrangement sequence;
the area is great after the sound board expandes, and certain crooked pitch arc has, so the sound board is not like the same simple regulation direction of plane cover plate, need the sound function of every place on analysis sound board surface, for the convenience multiple spot contrast, divide into a plurality of sound receiving units with the sound board according to certain division rule, each sound receiving unit is observed alone, the judgement is concentrated at last, for the convenience contrast between a plurality of sound receiving units is judged, all number each sound receiving unit preferably, each sound receiving unit is conveniently discerned.
Of course, when step S1 is executed, each of the sound receiving units has the same size. The comparison is convenient, and the judgment accuracy is higher.
S2: a vibration receiver is arranged behind each sound receiving unit;
the sound receiving plates reflect sound waves, meanwhile, the sound receiving plates also receive images of the sound waves, the sound receiving plates vibrate synchronously under the vibration of the sound waves, the larger the energy of the sound waves received in a unit space is, the larger the vibration amplitude is, and in order to monitor data of each sound receiving unit, a vibration receiver needs to be installed behind each sound receiving unit to receive the vibration of the sound receiving units, and the vibration receiver can display and read the vibration.
Similarly, when step S2 is executed, the number of vibration receivers installed behind each sound receiving unit is the same, so as to ensure the sameness between the vibration of the sound receiving unit and the reception of the vibration receivers, ensure that the calibration data is accurate and effective, and have high reliability.
S3: acquiring a sound receiving unit with the largest vibration amplitude, and marking the sound receiving unit;
the sound receiving unit with the largest vibration amplitude is closest to the direction of the returned sound wave or has the largest expansion area facing the direction of the returned sound wave, generally, the sound receiving unit is closest to the direction of the returned sound wave.
S4: drawing horizontal and vertical coordinate axes by taking the marked sound receiving units as coordinate axis origins, and dividing the sound receiving plate into four areas;
in fact, the two axes are perpendicular to each other, the sound-collecting plate is divided into four parts, and the sound waves reflected by the sound-collecting plate in the four regions are the total amount of the sound waves diffused in four directions around the sound waves.
S5: acquiring the number of the sound receiving unit of each area, and calculating the sum of the vibration amplitudes of the sound receiving units of each area;
and (3) counting the four regions independently, wherein each region has a plurality of sound receiving units vibrating, the vibration of each sound receiving unit is in direct proportion to the reflected and diffused sound wave, and then calculating the sum of the vibration amplitudes of the sound receiving units in each region can correspondingly obtain the sum of sound wave energy which is prosperous in four directions of the sound receiving board.
