Noise control method and control device for belt conveyor

The invention discloses a noise control method and device for a belt conveyor, and the method comprises the following steps: A, obtaining the vibration conditions of a truss and a rubber belt during the operation of the belt conveyor, judging whether the truss and the rubber belt resonate or not, and if yes, adjusting the tension of the rubber belt within the safety range of the tension of the rubber belt, and changing the vibration frequency of the rubber belt; most of operation noise of the belt conveyor is from same-frequency vibration of a steel structure and a rubber belt, the noise control method of the belt conveyor obtains vibration conditions of a truss and the rubber belt when the belt conveyor operates, judges whether the truss and the rubber belt resonate or not based on the vibration conditions of the truss and the rubber belt, and judges whether the belt conveyor operates or not after determining that resonance occurs. After the tension of the adhesive tape is changed, the tension state of the a
