Abstract

The invention discloses an electromechanical equipment fault diagnosis method and system. A vibration speed sensor and a vibration acceleration sensor are arranged on different measuring points in thevertical direction of electromechanical equipment bearings; the vibration speed sensor and the vibration acceleration sensor are used for collecting vibration signals; the method comprises the following steps that the electromechanical equipment transmits the vibration signals to a cloud end; the cloud end carries out median filtering and wavelet packet noise reduction treatment on the vibrationsignals, so as to obtain a de-noised signal; the cloud end carries out cepstrum analysis on the de-noised signal, so as to obtain a cepstrum signal; and the cloud performs fault diagnosis according tothe cepstrum signal. The electromechanical equipment fault diagnosis method and system are used for solving the technical problem that the failure diagnosis method cannot detect the imbalance and misalignment of the electromechanical equipment in the prior art, and the accuracy of fault diagnosis is improved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a method and system for fault diagnosis of electromechanical equipment. Background technique [0002] In the modern installations of large and medium-sized enterprises such as iron and steel, coal mines, and petrochemicals, various large and complex mechanical equipment such as reducing and sizing machines, motors, pumps, fans, air compressors, and gearboxes play a pivotal role. With the development of technology and the continuous modernization of equipment management, the analysis of equipment failure has been greatly improved from the initial simulation analysis to the current digital analysis technology, and the analysis speed and performance have been greatly improved. [0003] Oil analysis technology is to obtain the information of the lubrication and wear state of the equipment by analyzing the performance changes of the lubricant or working medium used in the tech...
