Abstract
A noise source monitoring apparatus includes: a first storage unit storing captured image data; a second storage unit storing observed waveform data; a processing unit calculating, for each of the switch units, the degree of correlation between occurrence of a noise and operation of the switch unit, based on the captured image data and the observed waveform data; and a display control unit causing a display unit to display information indicating the degree of correlation.
Claims15
A noise source monitoring apparatus, comprising:
- a first storage unit configured to store captured image data containing a captured image of a plurality of switch units and a capture time of the captured image, the switch units being configured to switch on and off drive units for driving a plurality of devices, the drive units being arranged around a control device for controlling an industrial machine, the plurality of devices being different from the industrial machine;
- a second storage unit configured to store observed waveform data containing an observed waveform displayed on an oscilloscope connected to the control device and an observation time of the observed waveform;
- a processing unit configured to calculate, for each of the switch units, a degree of correlation between occurrence of a noise generated in the control device and operation of the switch unit, based on the captured image data and the observed waveform data;
- and
- a display control unit configured to cause a display unit to display information indicating the degree of correlation.
