Abstract

The invention provides an equipment operation frequency control method and an air conditioner controller. The method comprises the following steps that 1, the first sound frequency of a first noise source and the second sound frequency of a second noise source are periodically obtained; 2, if the sound frequency difference between the first sound frequency and the second sound frequency is within a preset frequency range,an adjustment frequency is randomly generated according to a preset value range; and 3, the operation frequency of the first noise source or the second noise source is adjusted according to the adjustment frequency. In the scheme, if the sound frequency difference of the first sound frequency and the second sound frequency obtained periodically is within the preset frequency range, it is determined that the first noise source and the second noise source of an air conditioner generate the beat frequency sound. Through the randomly generated adjusting frequency, the operation frequency of the first noise source or the second noise source is adjusted, so that the beat frequency sound generated by the air conditioner is eliminated, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method for controlling the operating frequency of equipment and an air conditioner controller. Background technique [0002] Air conditioners are one of the most common electrical appliances in daily life. When the air conditioner is running, there are usually more than two noise sources. When the sounds of two noise sources have similar frequencies and amplitudes, a beat frequency sound will be generated, which seriously stimulates and affects the user's hearing. Therefore, how to eliminate the beat frequency sound produced by the air conditioner is an urgent problem to be solved at present. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method for controlling the operating frequency of equipment and an air conditioner controller, so as to eliminate beat frequency sounds generated by the air conditioner. [0004] In order...
