Abstract

The invention belongs to the mechanical equipment diagnosis technical field and relates to a rotating mechanical equipment automatic diagnosis system and method. The method has the advantages of low cost, high stability, convenient installation and use, convenient maintenance, high precision and the like. With the rotating mechanical equipment automatic diagnosis system and method adopted, the automatic diagnosis of the health state of rotating mechanical equipment under different rotational speed conditions can be realized, specific failure modes can be diagnosed, so that trouble-shooting iscarried out in a targeted manner; and equipment state characteristics in a time-frequency joint domain which are included in equipment dynamic signals can be displayed with higher precision, so that adiagnosis technology is easy to operate. The rotating mechanical equipment automatic diagnosis system and method can remotely monitor the operation of the rotating mechanical equipment and significantly reduce inspection costs and improve inspection frequency.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment diagnosis, in particular to an automatic diagnosis system and method for rotating mechanical equipment. Background technique [0002] The core components of high-end precision rotating machinery equipment (such as wind turbine transmission systems, axle box devices of high-speed EMUs) are prone to failure under severe fluctuations in speed and load, and the harm of failure to equipment is compared with constant speed or slow change The situation is more serious. The existing conventional non-stationary mechanical equipment health monitoring mainly relies on the key phase order analysis technology. The key phase order analysis technology first uses the key phase hardware device to measure the speed of the equipment, and then uses the speed information to order the collected vibration or acoustic signals. Secondary analysis to identify fault characteristics. Using the key phase hardwa...
