Voiceprint monitoring device capable of adaptively adjusting monitoring position and adjusting method

The invention discloses a voiceprint monitoring device capable of adaptively adjusting a monitoring position, which is characterized in that a stepping motor is arranged on one side in a fixed mounting box through a moving shell, a sound sensor is arranged at the output end of the stepping motor, a driving mechanism is arranged on the rear side of the moving shell, a monitoring system is arranged in the fixed mounting box, and the monitoring system is connected with the moving shell. The monitoring system comprises a power supply module, an industrial personal computer module, a driving single-chip microcomputer module, an amplification module, an acquisition card module and a vibration sensor. Different monitoring positions and angles are quantitatively evaluated by using the average value of the Pearson correlation coefficients between the sound sensor and the vibration sensor group, the optimal monitoring position can be automatically obtained, the detection effect during transformer voiceprint monitoring
