Problems solved by technology

However, when only data detected during normal operation of industrial machinery is collected, even if it is divided into data for model creation and data for verification, the appropriateness of the division may become a problem at a certain rate
Also, since there is no runtime data for the exception, it is impossible to verify the response of the created model to the exception data

Abstract

A diagnostic apparatus of the invention acquires the normal data related to an operating state during normal operation of an industrial machine, stores the normal data, generates a learning model by learning based on the stored normal data, and performs an estimation process for normality or abnormality of an operation of the industrial machine by using the learning model. The diagnostic apparatusof the invention further generates the verification data including at least one piece of abnormal data based on the stored normal data to verify validity of the learning model on receiving a result of the estimation process by using the learning model based on the verification data.

Description

technical field [0001] The invention relates to a diagnostic device. Background technique [0002] In manufacturing sites such as factories, a method of monitoring and diagnosing the operating status of industrial machinery such as robots and machine tools installed on the production line has been introduced to prevent the production line from stopping and to quickly restore it when the production line is stopped. installation. [0003] As a device for diagnosing the operating status of industrial machinery, for example, through the network, data such as the position, speed, and torque of motors detected in each industrial machinery, sounds and images detected by sensors installed on industrial machinery and other data are monitored, and when the data tends to indicate an abnormality, it is diagnosed as an abnormality in the operation of the industrial machine (for example, Japanese Patent No. 6453504 and Japanese Patent Laid-Open No. 2019-012473). In order for the diagnos...
