AI Technical Summary

Problems solved by technology

This traditional analog envelope system suffers from the following disadvantages: high current, low dynamic range, bulky, unsuitable for inclusion in application-specific integrated circuits (ASICs), and poor temperature performance
However, this can result in long transfer and display times and the data can be difficult to display or interpret
Sending, displaying, and interpreting this data can require significant energy, time, and expertise, thereby slowing down measurements and analysis

Embodiment Construction

[0038] figure 1 A system 10 is shown for monitoring the condition and optionally predicting the remaining life of a plurality of bearings 12 during their use. The illustrated embodiment shows two rolling element bearings 12, however, the system 10 according to the invention may be used to monitor and optionally predict the remaining life of one or more components of any type, and the components need not be of the same type or size. System 10 includes a plurality of sensors 14 configured to obtain data related to one or more factors affecting the remaining life of each bearing 12 . The sensor 14 may be integrated with the bearing 12, which may be placed near the bearing 12 or remotely therefrom.

[0039] The inner and / or outer rings of a bearing 12 that may be monitored using a system or method according to an embodiment of the present invention may be of any size and have any load capacity. For example, the inner and / or outer ring may have a diameter of up to several meters...

Abstract

A method for processing data (30) obtained from a condition monitoring system (10), which comprises the steps of obtaining an Acoustic Emission (AE) time waveform from at least one sensor (14) and digitally demodulating said AE time waveform.

Description

technical field [0001] The present invention relates to a method, system and computer program product for processing data obtained from a condition monitoring system for monitoring and optionally predicting the remaining life of components such as bearings, i.e. for predicting The moment when a service, replacement or remanufactured (remanufactured) part is needed or desired. Background technique [0002] Condition monitoring is the process of determining the state of machinery during operation. Condition monitoring enables problematic parts to be repaired before they fail, and not only helps plant personnel reduce the potential for catastrophic failure, but also allows them to order parts in advance, schedule labor, and plan other repairs during downtime. [0003] Components such as rolling element bearings are often used in critical applications where failure of these components in service would result in significant commercial loss to the end user. It is therefore impor...
