An embedded intelligent bearing monitoring system and its monitoring method

Abstract

The invention discloses a monitoring system for an embedded intelligent bearing, which includes a bearing body, a sensing element installed inside the bearing body, a signal processing module electrically connected to the sensing element, and a fusion analysis module for perception and decision-making; The invention also discloses a monitoring method of a monitoring system for embedded intelligent bearings, which specifically includes the following steps: 1. The signal processing module receives signals from sensing elements; Three states, and judge the running state of the bearing through the extracted fusion index; the present invention can self-perceive the vibration and temperature signals of the bearing and judge the fault degree of the bearing. The sensing element is installed inside the bearing, and the accuracy of the measured data is higher than before. The measurement method is higher, and the working status of the bearing can be judged more comprehensively and accurately through the fusion of multiple feature indicators.

Description

technical field [0001] The invention belongs to the technical field of intelligent bearings, and in particular relates to a monitoring system for embedded intelligent bearings and a monitoring method thereof. Background technique [0002] Rolling bearing is one of the important parts of mechanical equipment. Its main function is to support the mechanical rotating body and ensure the rotation accuracy. Due to the advantages of small friction coefficient, high transmission efficiency, and low heat generation, rolling bearings are widely used in aerospace, high-speed rail and other fields, and have a significant impact on national economic development and national defense construction. However, rolling bearings may be damaged due to various reasons during operation, such as poor lubrication, overload, and improper assembly may cause premature damage to the bearings. Once the failure of the bearings leads to the shutdown of mechanical equipment, it will cause huge property losse...
