Embedded intelligent bearing monitoring system and monitoring method thereof

Abstract

The invention discloses a monitoring system of an embedded intelligent bearing. The monitoring system comprises a bearing body, a sensing element installed in the bearing body, a signal processing module electrically connected with the sensing element and a fusion analysis module used for sensing and decision making. The invention further discloses a monitoring method of the embedded intelligent bearing monitoring system. The monitoring method specifically comprises the following steps that 1, the signal processing module receives signals from the sensing element; 2, a fusion analysis module extracts related characteristic indexes, divides the bearing operation state into three states, and judges the operation state of the bearing through the extracted fusion indexes. The method is advantaged in that vibration and temperature signals of the bearing can be sensed automatically, the fault degree of the bearing can be judged, the sensing element is installed in the bearing, precision of measured data is higher than that of a previous measurement mode, and a working state of the bearing can be judged more comprehensively and accurately in a multi-feature-index fusion mode.

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...
