| 摘要 |
The purpose of the present invention is to provide a machine diagnostic device which assists with sensor attachment such that malfunction sensing performance may be maintained even after maintenance of a device. The machine diagnostic device (2) comprises: a sensor data acquisition part (21) which acquires time-series sensor data which is measured by sensors (11) which are attached to a machine (1) which has one or more operating modes; a learning unit (25) which statistically processes the sensor data prior to detachment of the sensors and computes a normal operation model; a malfunction diagnostic unit (23) which diagnoses a malfunction of the machine on the basis of the sensor data and the normal operation model; and a sensor adjustment unit (24) which, when the sensors are re-attached to the machine after the sensors have been detached therefrom, displays, in a display unit, as a sensor adjustment mode, discrepancies between the normal operation model prior to the detachment of the sensors and the post sensor attachment sensor data. |
