An obstacle determination unit determines whether an obstacle is present in a periphery of the work machine. An action detection unit detects an action of an operator of the work machine. An action determination unit determines whether the detected action is a confirmation action executed at the time of safety confirmation. A notification unit changes a mode of notification when the action is determined to be the confirmation action.

Work machine obstacle notification system and work machine obstacle notification method

An obstacle determination unit determines whether or not an obstacle is within a detection range being a detection target of the obstacle. A notification unit gives notification indicating the obstacle when determined as the obstacle being present. An operation input unit receives an operation to the display unit for changing the detection range. A change unit changes the size of the detection range based on the operation.

Obstacle notification system for work machine and obstacle notification method for work machine

A work vehicle periphery monitoring system includes: an alarm range storage unit that stores an alarm range, in which an alarm output is required when an object is present, in a detection range of an object detection device that detects an object present in a periphery of a work vehicle; a work mode determination unit that determines a work mode of the work vehicle; an alarm range changing unit that changes the alarm range in the detection range when it is determined that the work mode is a specific work mode; and an alarm control unit that causes an alarm device to output an alarm when an object is present in the alarm range.

Work vehicle periphery monitoring system and work vehicle periphery monitoring method

A periphery monitoring device includes cameras that detects a periphery of a hydraulic shovel, a periphery monitoring monitor that displays a bird's-eye image based on image information acquired by the cameras, and a state switching control unit that controls mode switching between a periphery monitoring mode and a monitoring pause mode. The state switching control unit transitions to the periphery monitoring mode in a case where an input of a key-on manipulation with respect to the hydraulic shovel is received in the monitoring pause mode. In the monitoring pause mode, it is possible to transition to the periphery monitoring mode in time faster than transition from a power-OFF state.

Periphery monitoring device, work machine, periphery monitoring control method, and display device

A surroundings monitoring device of a crawler-type work machine includes: cameras configured to take images of surroundings of the crawler-type work machine; a display unit configured to display the images taken by the cameras; and a controller configured to superimpose an outer-edge guide image generated based on the farthest position of an undercarriage from a revolution center of the crawler-type work machine on the display unit.

Periphery monitoring device for crawler-type working machine

A work machine includes plural cameras, a display unit and a controller controlling the cameras and the display unit. The controller includes an overview image generator generating an overview image from the images by the cameras, an image superimposing unit superimposing a top view image of the work machine on the overview image, a working-equipment display unit putting a part of working equipment in the top view image of the work machine in non- or transparent-display, and an operation judging unit judging at least one of operation of the working equipment and travel of the work machine. When the operation judging unit judges the operation of the working equipment etc. is performed, the working-equipment display unit displays the top view image of the work machine without displaying at least one part of the working equipment or with transparently displaying the at least one part of the working equipment.

Working machine

A surrounding monitoring device of a work machine includes: a display unit; a plurality of cameras acquiring a surrounding condition of the work machine; an image processing unit generating a bird's-eye image indicating the surrounding condition of the work machine on the basis of images imaged by the cameras; a work machine operation detection unit detecting an operation of the work machine; and a display control unit displaying, on the display unit, a single camera image imaged by one or more cameras, of the plurality of cameras, the bird's-eye image, mechanical gauge display, menu display, and/or breakdown information display. Further, when the operation of the work machine is detected, the display control unit performs control of enlarging surroundings of the work machine on the bird's-eye image, compared with surroundings of the work machine on the bird's-eye image before the operation of the work machine is detected.

Surrounding monitoring device of work machine and method of monitoring surroundings of work machine

A work vehicle includes a vehicle body, a working implement, a camera, and a display control unit. To the vehicle body, front tires are mounted. The working implement is movably coupled to the vehicle body and at least a part thereof is arranged anterior to the front tires. The camera is arranged at a front portion of the vehicle body and shoots an image of an anterior area outside the vehicle body as a shooting area. The display control unit causes a display device to display a shot image shot by the camera and a first guide image which indicates a first projection position obtained by projecting a first site of the working implement on a plane including ground-contacting surfaces of the front tires in a superimposed manner.
