Abstract
Provided are a system and a method for diagnosing a state of mechanical equipment. More particularly, provided are a system and a method for diagnosing a state of mechanical equipment, wherein a health index is calculated for various levels in the equipment using one or more sensor parameter values related to individual components of the equipment, and then a current state value of the equipment is finally derived.
Claims20
A system for diagnosing a state of mechanical equipment, the system comprising:
- a detection part configured to sense parameter values of individual components;
- a state value derivation part configured to calculate a state value of the mechanical equipment in a time series manner from the parameter values;
- a database configured to store the state value;
- and
- a controller.
2 more elements
A method for diagnosing a state of mechanical equipment, the method comprising:
- deriving or calculating health indexes of individual parameter nodes from sensor parameter values;
- providing initial weightings for the individual parameter nodes, individual component nodes, and individual module nodes;
- updating the weightings for the individual parameter nodes, the individual component nodes, and the individual module nodes from an immediately previous time point;
- and
- deriving or calculating from the health indexes at a current time point of the individual parameter nodes connected to the individual component nodes, new health indexes at the current time point for the respective nodes.
