The invention, which relates to the technical field of sound wave detecting, provides a sonar sound-receiving board control method. The method comprises the following steps: S1, dividing a sound-receiving shield plate into at least one sound receiving unit and numbering the sound receiving unit according to the arrangement order; S2, installing a vibration receiver behind each sound receiving unit; S3, acquiring one sound receiving unit with the largest vibration amplitude and carrying out marking; S4, with the marked sound receiving unit as the origin of a coordinate axis, drawing horizontaland vertical coordinate axes and segmenting the sound-receiving shield plate into four areas; S5, acquiring a number of each sound receiving unit in each area and calculating the sum of vibration amplitudes of the sound receiving units in each area; and S6, determining whether the sum of vibration amplitudes of the sound receiving units in all areas are same; if so, completing adjustment; and if not, adjusting the sound-receiving shield plate to rotate towards the area with the largest vibration amplitude, and repeating the S3. According to the sonar sound-receiving board control method, controlling becomes convenient; the precision is high; the manual operation is avoided; adjustment control can be performed at any time; the adjustment efficiency is high; and the imaging effect is good.
