Abstract
To provide a remote operation system and a remote operation device for a work machine that enhance operability while avoiding audio feedback caused by a microphone and a speaker respectively provided in the remote operation device and the work machine. Output of work machine-side audio (audio collected by an actual machine external microphone 414) via a remote speaker 222 is reduced or output from the remote speaker 222 is stopped, when remote operation device-side audio (audio collected by a remote microphone 214) is output via an actual machine speaker 422. Thus, collection via the remote microphone 214 of the audio output from the remote speaker 222 is suppressed.
Claims8
A remote operation assistance system for assisting work of a work machine via a remote operation device, the remote operation assistance system comprising:
- an actual machine microphone that is installed in the work machine and collects audio from the work machine side as work machine-side audio;
- a remote speaker that is installed in the remote operation device and outputs the work machine-side audio collected via the actual machine microphone;
- a remote microphone that is installed in the remote operation device and collects audio from the remote operation device side as remote operation device-side audio;
- and
- an actual machine speaker that is installed in the work machine and outputs the remote operation device-side audio collected via the remote microphone, wherein
- output of the work machine-side audio via the remote speaker is reduced or output of the work machine-side audio via the remote speaker is stopped, in a case where the remote operation device-side audio is output via the actual machine speaker.
A remote operation device for assisting remote operation of a work machine, the remote operation device comprising:
- a remote speaker that outputs work machine-side audio collected via an actual machine microphone installed in the work machine;
- and
- a remote microphone that collects remote operation device-side audio output via an actual machine speaker installed in the work machine, wherein
- output of the work machine-side audio via the remote speaker is reduced or output of the work machine-side audio via the remote speaker is stopped, when the remote operation device-side audio is output via the actual machine speaker.
