摘要： In an abnormality detector apparatus (4), a signal processor unit (10) performs frequency analysis on data of a current or a voltage in different first and second time intervals to retrieve a first drive frequency corresponding to a maximum peak value of a spectrum in the first time interval and a second drive frequency corresponding to a maximum peak value of a spectrum in the second time interval; adjusts a frequency axis of one spectrum such that the maximum peak values coincide with each other, and calculates an averaged spectrum relating to the adjusted and unadjusted spectra; and retrieve an abnormal peak value equal to or more than a predetermined threshold value at a frequency different from the drive frequency having the maximum peak value based on the averaged spectrum; and determine an abnormal state of the motor (2) depending on presence or absence of the abnormal peak value.

摘要： Provided is an information processing device that presents information for determining whether the installation state of a control device is appropriate. An information processing device (1) is provided with: an image recognition unit (151) that recognizes device identification images (ID codes 211) of a plurality of control devices (210) included in a captured image of a control panel (2); a device identification unit (152) that identifies model information and the installation positions of the control devices on the basis of the device identification images; a heat generation prediction unit (153) that predicts a heat generation state in the control panel on the basis of the model information and the installation positions of the control devices; and an output control unit (154) that outputs information about the predicted heat generation state.

摘要： Provided is an information processing device that generates a layout diagram corresponding to the actual configuration of a control panel. An information processing device (1) is provided with: an image recognition unit (151) that recognizes device-identifying images (ID codes 211) of control devices (210) included in a captured image in which an imaging device (camera 110) has captured an image of a control panel (2); a device specification unit (152) that specifies device-type information and an installation location for the control devices on the basis of the recognized device-identifying images; and a layout diagram generation unit (154) that generates a layout diagram of the various control devices on the control panel on the basis of the device-type information and installation location of the various specified control devices.

摘要： Provided is an abnormality diagnosis device capable of diagnosing an abnormality of a motor without setting many parameters. An abnormality diagnosis device (40) includes a current measuring unit (410) that measures a load current of the motor (20); a frequency analyzing unit (411) that performs frequency analysis of the load current; and a deterioration degree calculating unit (412) that calculates a degree of deterioration by adding up a preset number of intensity values from top in a preset frequency range.
