Embodiment Construction

[0036] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0037] Condition monitoring and health management of bearings has become an important branch and research hotspot of intelligent maintenance. More and more bearing condition monitoring and health management systems appear on the market to provide feasible solutions for bearing intelligent maintenance. However, since the bearing status and health management system is a black box, it is impossible to directly check whether the code inside is reliable and optimal. Even if ...

Abstract

The invention discloses a bearing state monitoring and health management system performance test and optimization method and system, and the method specifically comprises the steps: firstly, giving an accuracy index and a robustness index of the bearing state monitoring and health management system performance as evaluation indexes; testing and verifying the performance of the bearing state monitoring and health management system based on the bearing fault data as input and the fault data added with the random interference data; in the edge monitoring system, the actual fault state of the bearing is compared with the monitoring result of the edge monitoring system, and if the accuracy reaches the standard, a threshold value adjusting strategy is used; if the accuracy does not reach the standard, adjusting the strategy by using parameters; in a remote cloud platform system, according to comparison between the actual health state of the bearing and the predicted health state of the model, a parameter adjustment strategy of the model is adopted if the actual health state and the predicted health state of the model are inconsistent, more accurate system performance description can be obtained, and meanwhile edge monitoring system optimization and cloud platform remote system optimization are carried out respectively by optimizing a feedback mechanism.

Description

technical field [0001] The invention belongs to the technical field of mechanical diagnosis intelligence and digitization, and in particular relates to a bearing state monitoring and health management system performance testing and optimization method and system. Background technique [0002] Bearings are one of the most common transmission components in rotating machinery, and bearings are widely used in aerospace, industrial production, and transportation. The normal and safe operation of bearings plays an important role in the smooth operation of the entire rotating machinery system. However, due to the harsh working environment and the influence of high temperature and high pressure during operation, bearings are also the most vulnerable transmission components in rotating machinery. Once the bearing fails, it will cause economic losses and may even threaten personal safety. It can be seen that it is necessary to carry out condition monitoring and health management on ...
