Embodiment 1

[0025] Embodiment 1: as figure 1 As shown, a real-time bearing fault diagnosis system based on case reasoning, including sensor 1, multi-channel acquisition card 2, data analysis module 3, distance calculation module 4, judgment module 5, case adjustment module 6, diagnosis case database 7, case Generation module 8, alarm module 9, maintenance scheduling module 10;

[0026] The sensor 1 is used to collect real-time analog signals of vibration velocity and analog signals of vibration acceleration at each key position of the mechanical system, that is, on the measuring point, and transmit them to the multi-channel acquisition card 2;

[0027] The multi-channel acquisition card 2 is used to convert the analog signal collected by the sensor 1 into a digital signal as a sample to be tested;

[0028] The data analysis module 3 calculates the standard deviation of the vibration velocity signals in the samples to be tested and the historical cases, and obtains the kurtosis, margin, s...

Abstract

The invention discloses a real-time fault diagnosis system for bearings based on case reasoning, which includes a sensor, a multi-channel acquisition card, a data analysis module, a distance calculation module, a judgment module, a case adjustment module, a diagnosis case database, a case generation module, an alarm module, Maintenance scheduling module. The present invention adopts human-computer interaction technology, and can self-learn the real-time collected signals to be diagnosed according to the stored historical cases and continuously updated historical cases, so as to realize the fault diagnosis of the signals to be diagnosed, and further carry out alarm and maintenance report Processing, etc., to provide accurate and timely reference materials for the real-time failure results of bearings.

Description

technical field [0001] The invention relates to a case-based reasoning bearing real-time fault diagnosis system, which belongs to the field of equipment maintenance and fault diagnosis. Background technique [0002] In the electromechanical industry, bearings are one of the most widely used basic parts. Whether it is ordinary mechanical equipment, means of transportation or aviation, navigation, aerospace and other fields. Obviously, it is very important to ensure that the bearing can perform properly under various environmental conditions. Bearings are one of the most important components in mechanical design. Widespread use makes lighter and more durable bearings still need to be introduced. The design of bearings is very complex, including manufacturing, maintenance and repair. The phenomenon that the bearing loses its specified function during work, resulting in failure or failure to work normally is called failure. Bearing failure can be divided into normal failure...
