Abstract

The invention relates to the technical field of bearing fault detection, in particular to a detection signal processing device and method. The method comprises the following steps: an audio processing line receives a first sensor signal; after the first sensor signal is processed, the processed first sensor signal is output to an earphone; and if a recording instruction sent from a control unit is received, the first sensor signal is sampled, and the sampled first sensor signal is converted into a digital signal, and the digital signal is sent to a control unit to be stored. When a detection device carries out real-time auscultation on a mechanical device, detection data is converted into the digital signal so as to store the digital signal by a lossless audio format, so that the digital signal can be stored in external storage devices, including an SD (Secure Digital Memory) card, a data acquisition card with large volume and high price does not need to be used, cost is lowered, and circuit design is simplified.

Description

【Technical field】 [0001] The invention relates to the technical field of bearing fault detection, in particular to a detection signal processing device and method. 【Background technique】 [0002] As modern production enters scale and automation, rolling bearings, as basic rotating machinery parts, are widely used in various fields of national production, and their operating status has a great impact on the normal operation of equipment. According to statistics, about 30% of mechanical failures in our country are caused by bearing damage every year. During the operation of bearings, due to fatigue wear, indentation, cracks, surface peeling, etc., the bearings are damaged and shock vibration occurs. Once a failure occurs, In the slightest, it will affect the work of the entire equipment, and in the severest case, it will cause personal injury. In order to better monitor the operating state of the bearing and avoid sudden failures, the existing technology usually detects the b...
