Abstract
Official abstract text for this publication.
Provided is an abnormality detecting device for a construction machine that can estimate an abnormality occurring to a component (engine, pump, etc.) of the construction machine based on the relationship among a plurality of pieces of sensor information and thereby prevent machine failure. A correlation coefficient calculation unit 102 calculates correlation coefficients between time-series sensor values acquired by a plurality of sensors 101 . A correlation coefficient comparison unit 103 compares the correlation coefficients and calculates the degree of difference between each correlation coefficient and other correlation coefficients. An abnormality judgment unit 104 judges that an abnormality has occurred to a part related to a sensor when the degree of difference calculated in regard to the sensor exceeds a preset value.
First claim
Opening claim text (preview).
The invention claimed is: 1. An abnormality detecting device for a construction machine equipped with a plurality of sensor means placed at a plurality of parts of the construction machine, the sensor means detecting a plurality of related physical states and outputting a plurality of pieces of sensor information, comprising: correlation coefficient calculation means which receives the plurality of pieces of sensor information outputted from the plurality of sensor means, generate…
