Title
(EN) CONTROL METHOD FOR OPERATING FREQUENCY OF COMPRESSOR, APPARATUS, AIR CONDITIONER, STORAGE MEDIUM, AND PRODUCT
(FR) PROCÉDÉ DE COMMANDE POUR LA FRÉQUENCE DE FONCTIONNEMENT D'UN COMPRESSEUR, APPAREIL, CLIMATISEUR, SUPPORT DE STOCKAGE ET PRODUIT
(ZH) 压缩机工作频率控制方法、装置、空调、存储介质及产品
Abstract
(EN) A control method for the operating frequency of a compressor, an apparatus, an air conditioner, a storage medium, and a product. Sound signals emitted by a compressor can be captured when the compressor is operating at different operating frequencies, and by means of performing frequency spectrum analysis on the sound signals at different frequencies, a resonant abnormal sound signal in the sound signals can be determined via integrating amplitude and bandwidth; an operating frequency prone to causing resonance during operation of the compressor can thereby be determined, and the operating frequency prone to causing resonance is consequently set as “blacklisted” when the compressor is operating, i.e. the compressor is controlled to not operate at the operating frequency prone to causing resonance, thus preventing resonance and reducing the operating noise of the compressor.
(FR) L'invention concerne un procédé de commande de la fréquence de fonctionnement d'un compresseur, un appareil, un climatiseur, un support de stockage et un produit. Des signaux sonores émis par un compresseur peuvent être capturés lorsque le compresseur fonctionne à différentes fréquences de fonctionnement, et par l'exécution d'une analyse de spectre de fréquence sur les signaux sonores à des fréquences différentes, un signal sonore anormal résonant dans les signaux sonores peut être déterminé par l'intégration d'amplitude et de bande passante ; une fréquence de fonctionnement susceptible de provoquer une résonance pendant le fonctionnement du compresseur peut ainsi être déterminée, et la fréquence de fonctionnement susceptible de provoquer une résonance est par conséquent définie comme « mise sur liste noire » lorsque le compresseur fonctionne, c'est-à-dire que le compresseur est commandé pour ne pas fonctionner à la fréquence de fonctionnement susceptible de provoquer une résonance, empêchant ainsi une résonance et réduisant le bruit de fonctionnement du compresseur.
(ZH) 一种压缩机工作频率控制方法、装置、空调、存储介质及产品,在压缩机以不同工作频率进行工作的过程中,可以采集得到压缩机发出的声音信号,通过对不同频率下的声音信号进行频谱分析,结合幅值以及带宽,可以确定声音信号中的共振异音信号,从而可以确定压缩机工作过程中容易发生共振的工作频率,进而,在压缩机工作的过程中,将容易发生共振的工作频率设为"黑名单",即控制压缩机不在容易发生共振的工作频率下工作,从而避免共振,减少压缩机的工作噪音。
