Abstract
Official abstract text for this publication.
A noise generation cause estimation device capable of easily estimating the cause of noise generation in a factory is connected for communication with a plurality of machines in the factory. The noise generation cause estimation device is provided with a noise information acquisition unit configured to acquire noise information generated in the machines, an operation information acquisition unit configured to continually acquire operation information of all the machines, and a determination unit configured to learn the relevance between the noise information and the operation information. The determination unit is provided with a state observation unit configured to observe the noise information and the operation information as state variables indicative of a current state of the environment and a learning unit configured to form a plurality of clusters including the state variables.
First claim
Opening claim text (preview).
The invention claimed is: 1. A noise generation cause estimation device connected for communication with a plurality of machines in a factory, the noise generation cause estimation device comprising: a processor configured to acquire noise information generated in the machines, continually acquire operation information of all the machines, learn the relevance between the noise information and the operation information, observe the noise information and the operation information as state variables indicative of a current state of the environment, form a plurality of clusters including the state variables, identify the clusters corresponding to the state variables, and extract the operation information constituting the cause of noise generation, based on principal components of the identified clusters; and a display configured to display the operation information constituting the noise generation cause. 2. The noise generation cause estimation device according to claim 1 , wherein the display is further configured to display a time-series change of the noise information and operation contents of the machines as the operation information. 3. The noise generation cause estimation device according to claim 1 , wherein the display is configured to highlight the operation information constituting the noise generation cause. 4. The noise generation cause estimation device according to claim 1 , wherein the processor is further configured to hold a data base in which maintenance information is defined according to contents of the noise information or the operation information constituting the noise generation cause, and the display is configured to display the maintenance information together.
