ACOUSTICAL MACHINE CONDITION MONITORING

摘要

A machine and/or a bearing is usually analyzed by several different methods, each one looking at a different aspect of a machine/bearing. This is at least in part due to the fact that we do not know what sort of failure it will be and what caused it. Different failures have different ways of breaking down and thus give different indications that something is not completely right. A machine/bearing condition monitoring unit will then preferably comprise many different analysis methods of trying to predict and detect failures. As a user it can be difficult to assess all the different alarm indications from the different methods. Therefore according to the invention, an alarm voting controller determines if an alarm should be made or not. The alarm voting controller analyzes the alarms from the individual methods and possibly how serious each one is and then outputs a single, for example, go/no go, pass/fail, or pass/warning/fail indication to a user.
