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. The sign image M is an image which represents a moving manner of a work machine. Thus, regardless of the distance between the work machineand the worker, reliability of a notification about the moving manner of the work machinefor 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.

Work assistance system and work assistance composite system

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.

Image processing device and image processing method

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.

Notification system

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, upper revolving body) and a second component (upper revolving body, bucket(working unit)) that constitute working machine, based on a result of detecting an operation aspect of a remote operation device, control is performed on individual sound output aspects of a plurality of sound output devicesand, each arranged at different locations in a remote operation space for the operator who operates the remote operation device

Remote operation assistance device and remote operation assistance method

A display mode of a picked-up image in a central image output device(specified image output device) is variably controlled so as to display all of respective specified portions PPL and PPR of a pair of pillarsL andR configuring a cabin the central image output device(specified image output device). The specified portions PPL and PPR are part of the pillarsL andR overlapping a specified image region R that extends in a belt shape between left and right bezelsL andR.

Remote operation device, remote operation assistance server, remote operation assistance system, and remote operation assistance method

Provided is a construction machine capable of smooth exhaust and suppression of a leak of noise from an engine room, including an engine guard defining an engine room, a cooling fan disposed in the engine room, a projection element projecting upward beyond the engine guard, and an exhaust duct. The exhaust duct has a bent shape including a first duct section extending along an axial flow direction of the cooling fan from an upstream end portion surrounding a duct inlet to a connection portion and a second duct section extending upward from the connection portion and surrounding a duct outlet opened upward, also including an engine concealment section obstructing a direct view to an engine through the duct outlet from outside the engine room.
