摘要： A display mode of a picked-up image in a central image output device 2210 (specified image output device) is variably controlled so as to display all of respective specified portions PPL and PPR of a pair of pillars 4240L and 4240R configuring a cab 424 in the central image output device 2210 (specified image output device). The specified portions PPL and PPR are part of the pillars 4240L and 4240R overlapping a specified image region R that extends in a belt shape between left and right bezels 2210L and 2210R.

摘要： A device or the like capable of improving continuity of a moving image outputted to an image output device of a remote operation device even in circumstances where an inter-frame difference of the moving image becomes large. When it is predicted that a data amount of a captured image is to exceed a threshold in consideration of a detection result of a moving mode of a working machine, high frequency components exceeding a specified frequency in a second specified image area excluding a first specified image area of the captured image are eliminated Thus, the data amount of the captured image is reduced so that the data amount becomes equal to or smaller than the threshold. Then, not only inter-frame continuity of the first specified image area of an environment image outputted to an image output device of a remote operation device but also visibility by an operator is improved.

摘要： A system is provided which can achieve reliability of a notification about a moving manner of a work machine for a worker regardless of the distance between the work machine and the worker. A sign image M is projected onto a peripheral region of the worker (for example, a ground surface which is present in the vicinity of the worker to the extent that the worker is capable of visually recognizing the sign image M) by an unmanned aircraft 60. The sign image M is an image which represents a moving manner of a work machine 40. Thus, regardless of the distance between the work machine 40 and the worker, reliability of a notification about the moving manner of the work machine 40 for the worker is achieved compared to a case where the sign image M is projected onto an irrelevant place to the position of the worker.

摘要： Provided is a construction machine capable of accurately notifying a worker that a prime mover is in a drive state. The construction machine includes a prime mover, a heat exchanger, a fan that blows air to the heat exchanger, a controller, and notification units. Only when all of a plurality of notification judgment conditions, which include a condition that the prime mover is in a drive state and a drive sound condition for judging that the drive sound of the fan is low, are satisfied, the controller inputs a notification instruction to the notification units. With input of the notification instruction, the notification units perform notification that the prime mover is in a drive state.

摘要： There is provided a device or the like capable of causing a result of an operator, remotely operating a working machine, perceiving a motion aspect of the working machine to approximate to a result of the operator perceiving a motion aspect of the working machine when the operator gets on the working machine. When there is represented a relative motion of a first component (lower traveling body 410, upper revolving body 420) and a second component (upper revolving body 420, bucket 445 (working unit)) that constitute working machine 40, based on a result of detecting an operation aspect of a remote operation device 20, control is performed on individual sound output aspects of a plurality of sound output devices 2220, 2221 and 2222, each arranged at different locations in a remote operation space for the operator who operates the remote operation device 20.

摘要： A notification system includes: a notifier which notifies an operator of a state of a lifting magnet; a sensor which detects at least one of a voltage, an electric current, and an electric power supplied for exciting the lifting magnet; a determination part which determines, based on detection data from the sensor, whether an attraction quantity of the lifting magnet reaches a maximum attraction quantity after excitation of the lifting magnet is started; and a notification control part which causes the notifier to notify that the attraction quantity reaches the maximum attraction quantity when the determination part determines that the attraction quantity reaches the maximum attraction quantity.
