  • Publication number: 20240141616
    Abstract: Provided is a system or the like capable of reducing mental burdens on an operator who remotely operates a work machine, when an image range acquired by a real machine image pickup device loaded on the work machine is changed. A previous notice indicating a future change mode of a real space area projected in a work environment image displayed at a remote image output device 221 is output to a remote output interface 220. It is possible to make the operator who encounters a virtual sound source Vss displaced according to a displacement mode of the real space area and/or an icon image A1 in an arrow shape indicating the displacement mode of the real space area recognize beforehand that the real space area projected in the work environment image is to be displaced according to the displacement mode in the future.

  • Patent number: 11821170
    Abstract: A remote operation system for a working machine includes a control device enabling an operator wearing a wearable display to grasp the surrounding situation of himself/herself. The control device includes an operation intention judgment section judging the presence/absence of an operator's operation intention to a remote operation lever based on the contents of acquired judgment information, and a display image switching section. With judgment of presence of the operation intention, the display image switching section makes a working area image taken by a working area image taking camera be displayed in a particular display area of the wearable display. With judgment of absence of the operation intention, the display image switching section stops the display of the working area image in the at least a part of the particular display area and switches it to a surrounding visual-recognition allowing area allowing the operator to visually recognize the surroundings.

  • Publication number: 20230046933
    Abstract: There is provided a technique capable of appropriately controlling a warm-up completion timing of a work machine in view of scheduled use of the work machine. A warm-up period elapsed until a measurement value of an internal state variable satisfies a designated condition, i.e., warm-up is completed since a warm-up operation of a work machine 40 was started is predicted based on a measurement value of an external state variable with an operation of the work machine 40 stopped. The warm-up operation of the work machine 40 is started at a first designated time t1 as an appropriate timing based on the predicted warm-up period such that the measurement value of the internal state variable of the work machine 40 satisfies the designated condition by a second designated time t2.

  • Publication number: 20230046110
    Abstract: The possibility of a work machine 40 being affected by a disaster in a second designated area including an existence position of the work machine 40 is predicted based on an amount of rainfall in a first designated area. A hazard map representing a result of the prediction of the possibility of the work machine 40 being affected by a disaster in the second designated area is outputted to a remote output interface 220 in a remote operation apparatus 20 (a client) (or a management output interface 620 in a management client 60). Accordingly, a user can take measures to reduce the possibility of the work machine being affected by a disaster, for example, to communicate with the persons involved in order to move the work machine 40 from a current position.
