A centralized control method, device and system for multiple electronic noise reduction devices

Abstract

The invention discloses a centralized control method for multiple electronic noise reduction devices. The method comprises steps of: receiving noise information collected by respective electronic noise reduction devices, the noise information including the frequency, the amplitude and the phase of the noise; and analyzing and sorting the noise information according to a preset strategy to obtain a sorting list; selecting the noise to be processed successively according to the order in the sorting list; generating a control signal based on historical data recorded in advance and corresponding to the noise to be processed to control and adjust the positions of the respective electronic noise reduction devices and the frequency, the amplitude and the phase of emitted offset sound waves. The centralized control method can perform centralized control on the positions of respective electronic noise reduction devices and the information of the emitted offset sound waves so that it is possible to avoid a case where the sum of the offset sound waves is too large or too small due to the independence of the respective electronic noise reduction devices, and improve the effect of noise reduction. The invention also discloses a centralized control device and system for multiple noise reduction devices, which are not described here.

Description

technical field [0001] The invention relates to the technical field of noise processing, in particular to a centralized control method, device and system for multiple electronic noise reduction devices. Background technique [0002] With the development of electronic technology, the power of electronic devices is getting bigger and bigger, the density of devices in electronic equipment is getting higher and higher, and the number of fans required is increasing, and the power is getting higher and higher, so the noise generated by the equipment is also increasing. Increasingly, the electronic noise reduction device can be used to generate sound waves with the same frequency and amplitude as the noise but opposite in phase to cancel the noise. [0003] However, for cabinet servers or large rack servers, it is generally necessary to install many electronic noise reduction devices to meet the noise reduction requirements. In this case, since there is no information interaction b...

[0003] However, for cabinet servers or large rack servers, it is generally necessary to install many electronic noise reduction devices to meet the noise reduction requirements. In this case, since there is no information interaction between the electronic noise reduction devices, but Running independently of each other, it is easy to cause the sum of the canceling sound waves to be too large and become new noise, resulting in poor noise reduction effect
