First Claim
Patent Images
1. An apparatus for diagnosing a damage factor of machinery, comprising:
- a machinery damage mode interactive query section configured to determine a damage factor event of the machinery and a characteristic feature thereof from input information;
a machinery damage factor diagnosis section configured to estimate a damage factor based on the information from the machinery damage mode interactive query section; and
a diagnosis result display section configured to indicate the estimated damage factor and a guidance for countermeasure to be taken against the damage factor, wherein said machinery damage factor diagnosis section includes a diagnosis matrix section including several small matrices featuring a plurality of machinery damage factors based on the damage factor event, the characteristic feature, and damage generated conditions, and a diagnosis engine section configured to generate one matrix by collecting several small matrices; and
said diagnosis engine section is configured to multiply an answering rate to query items of the damage mode interactive query section and a matching rate to an answer when all damage factors are set as 100%, and to miltiply a correction coefficient so as to calculate a damage probability.

Abstract
A vibration diagnosis is performed by using a vibration mode interactive query section grasping vibration event of a machinery such as turbine rotor and characteristic feature thereof from detected data information, a vibration factor diagnosis section estimating a vibration factor based on the information from the vibration mode interactive query section, and a diagnosis result display section indicating the estimated vibration factor and a guidance for countermeasure to be taken against the vibration factor.
