Abstract
A robot state monitoring device 2 comprises: a camera which captures an image of a robot 3 under the control of a controller; a moving image generation unit which associates video data of the robot 3 acquired by the camera with input/output signals DO[1], AO[1], DI[1], and AI[1] of the controller along a time axis 830, and generates a moving image showing a state change of the robot 3 and the input/output signals DO[1], AO[1], DI[1], and AI[1]; and a moving image playback device which plays back the moving image generated by the moving image generation unit The moving image generation unit acquires the values of the input/output signals DO[1], AO[1], DI[1], and AI[1] at the recording time of each frame under the same cycle as the frame rate of the video data.
Claims5
A state monitoring apparatus for an industrial machine, comprising:
- an imaging device that captures an image of the industrial machine under control of a controller;
- a video creation unit that associates a video data acquired by the imaging device with an input/output signal, which is at least one of an input or output signal of the controller, along a time axis, thereby creating a video showing a change in state of the industrial machine and a change in state of the input/output signal;
- and
- a video player that plays the video created by the video creation unit, wherein the video creation unit
- creates the video including a moving image display field that shows moving images of the industrial machine and a timeline field that shows the time axis, a frame bar extending parallel to the time axis, and a time chart field extending parallel to the time axis and adjacent to the frame bar,
- arranges multiple still images of the industrial machine at each frame along the time axis in the frame bar,
- arranges a time chart image showing the change along the time axis of the input/output signal selected by an operator in the time chart field, and
- arranges a time bar extending orthogonally to the time axis and over the time axis, the frame bar, and the time chart field.
