ROTATING DEVICE NOISE CONTROL METHOD AND CONTROLLER

摘要

A rotating device noise control method and controller are provided by the present invention, wherein the method includes: acquiring a noise sound wave signal returned from reference sensors and generated by rotating equipment; acquiring the rotating speed information of the rotating equipment; according to the rotating speed information, searching a predefined function mapping table to acquire a transfer function; generating a sound generating command according to the transfer function and the sound wave signal; sending the sound generating command to the secondary sound source sound generator, and making the secondary sound source sound generator generate the secondary sound wave, which is used for reducing the noise generated by the rotating equipment. The controller includes: a signal acquiring module, a rotating speed acquiring module, a searching module, the first generation module and a sending module. The present invention enables to solve the existing technology problem. The noise reduction purpose is truly realized without influence of target noise intensity generated by the rotating device.
