Problems solved by technology

[0004] This method in the prior art requires the user to be proficient in using the vibration and sound signal analyzer, which requires a high degree of specialization, high personnel detection and maintenance costs, and few types of detectable vibration and sound signals. Most of the analysis depends on one's own experience. If the experience is insufficient, the fault cannot be accurately located, which will affect the rapid recovery of production equipment

Abstract

A device fault detection method and apparatus, applied to a cloud server. The method comprises: obtaining, by a signal detector provided in a target device, first sampling data of a first vibration sound signal for the target device (S201); invoking a first detection model corresponding to the type of the first vibration sound signal from a pre-established detection model library (S202); and obtaining a preliminary fault diagnosis result for the target device on the basis of the first detection model and the first sampling data (S203). By means of the method, the diagnosis accuracy is improved, the personnel detection and maintenance costs are reduced, the target device can be recovered rapidly, and the types of detectable vibration sound signals are increased.

Description

technical field [0001] The present invention relates to the technical field of detection, and in particular, to a method and device for detecting equipment faults. Background technique [0002] In the production process, the production equipment will inevitably fail, making the production equipment unable to operate normally. Whether the production equipment can operate normally or not directly affects the production efficiency, so it is very important to detect and troubleshoot equipment failures in a timely manner. [0003] At present, most of the production equipment is tested by the user through an independently designed vibration and sound signal analyzer. The vibration and sound signal analyzer is equipped with a dedicated sensor probe device and a dedicated human-computer interaction device. The user inputs the setting parameters through the human-computer interaction operation device, samples the vibration sound signal through the sensor probe device, and analyzes ...
