The perimeter monitoring device comprises a vehicle information detecting part, a plurality of cameras, a bird's-eye image display unit, a plurality of obstacle detecting sensors, an obstacle processing part, and a camera image displaying unit. The vehicle information detecting part detects a speed of the work vehicle. The cameras capture image data regarding the surrounding of the work vehicle. The bird's-eye image display unit displays a bird's-eye image based on the image data. The obstacle detecting sensors detect obstacles in the surrounding. The obstacle processing part issues a warning when an obstacle is detected. The camera image displaying unit displays a camera image adjacent the bird's-eye image. The images are not displayed and the warning is not issued when the vehicle speed exceeds a threshold value.

A dump truck having a periphery monitoring apparatus is adapted to display an image of surroundings of the dump truck on a display apparatus. A rearward camera is attached to a vehicle body of the dump truck underneath a vessel of the dump truck and positioned forward of a rear edge portion of the vessel. A rearward camera image captured by the rearward camera includes the rear edge portion of the vessel, an area below the vessel, and an area rearward of the vehicle body. A display control section is configured to display the rear edge portion of the vessel in an upper region of the rearward camera image, to display a ground surface below the vessel in a lower region of the rearward camera image, and to display a vehicle body outer edge line obtained by vertically projecting an outer edge of the vessel onto the ground surface.

A management system for a mining machine on which tires are mounted and which travels in a mine by operation performed by a driver includes: a determination unit configured to determine whether or not a damaging operation damaging the tires has been carried out; a data acquisition unit configured to acquire damaging operation data indicating carrying out of the damaging operation, and one or both of driver identification data indicating a driver who has carried out the damaging operation and position data indicating a position of the mining machine on which the damaging operation has been carried out; and a data output unit configured to output association data containing the damaging operation data associated with one or both of the driver identification data and the position data.

System for managing mining machinery, method for managing mining machinery, and dump truck

A system for managing a mining machine is included in a mining machine that travels in a mine. The system includes: a positional information detecting unit configured to acquire positional information indicating a position of the mining machine; and a traveling path calculating unit configured to obtain, from each of a plurality of the mining machines, positional information about an actual traveling path on which each of the mining machines actually has traveled, and generate a reference traveling path in the mine with the obtained positional information.

System for managing mining machine and method for managing mining machine

The display system includes: stroke sensors that detect position information of working equipment relative to a body; a real image display unit; a combiner; and a display controller. Based on the position information of the working equipment, the display controller controls a displayed position of work-support information along a surface of the combiner and a depthwise displayed position of the work-support information defined in a forward direction relative to a cab. A projection image of the work-support information visible to an operator is thus displayed around the working equipment.

A periphery monitoring apparatus for a work vehicle includes a plurality of obstacle detection sensors, a warning region setting section and a warning section. The obstacle detection sensors are mounted on the work vehicle, and each of the obstacle detection sensors is configured to determine a relative position of an obstacle with regard to the work vehicle by detecting the obstacle in the surroundings of the work vehicle. The warning region setting section is configured to set a warning region, where it is necessary to warn a driver of a presence of the obstacle, according to a movement state of the work vehicle. The warning section is configured to warn a driver that the relative position of the obstacle is positioned in the warning region.

Work vehicle periphery monitoring apparatus

A perimeter monitoring device for a work vehicle is configured to monitor a surrounding of the work vehicle and display a monitored result on a display device. The perimeter monitoring device includes cameras, a bird's-eye image display unit, obstacle detecting sensors, a camera image specifying unit, and a camera image displaying unit. The camera image specifying unit is configured to specify one or more camera images in which one or more of obstacles are captured when the one or more of obstacles are detected by the obstacle detecting sensors. The camera image displaying unit is configured to display a relevant camera image in alignment with the bird's-eye image on the display device when a plurality of camera images are specified by the camera image specifying unit, the relevant camera image being ranked in a high priority ranking based on a priority order set in accordance with travelling states.

A work vehicle periphery monitoring system includes a plurality of imaging apparatuses which are attached to the work vehicle and image the periphery of a work vehicle to output image information, a display control unit which displays an image based on image information which is output from imaging apparatuses, and a pattern indicating information relating to the work vehicle periphery monitoring system on a monitor, and a pattern display control unit which changes a display position at which the pattern is displayed on the monitorbased on a display switching signal for switching a display of the monitor, before and after switching the display of the monitor.

A dump truck includes radars attached, facing backward, to a position projected sideward a front fender extended from a lower deck to an upper deck of a front side of the vehicle, in which an irradiation beam has an angle of dip to cross at least a front wheel; and radars attached, facing sideward, to the side of the lower deck, and the radars and the radars are arranged such that a horizontal forward detection limit line of each of the radar and a horizontal backward detection limit line of each of the radar overlap and the horizontal backward detection limit lines of the radar are directed to a side of a center plane of the vehicle to detect the obstacle in the side of the vehicle.

Dump truck with obstacle detection mechanism and method for detecting obstacle

A dump truck includes a body and a plurality of cameras. The body includes an upper deck and a main frame disposed in a longitudinal direction. The cameras are configured and arranged to obtain images to be combined to generate a bird's-eye image to monitor a periphery of the dump truck. The cameras include a front camera, a rear camera and side cameras. The front camera is disposed at the front of the upper deck to obtain an image of an area in front of the body. The rear camera is disposed at a rear end of the main frame to obtain an image of an area in rear of the body. The side cameras are respectively provided on left and right sides of the upper deck to obtain images of an area between diagonally to the front and diagonally to the rear of the body.

Dump truck

A periphery monitoring device () comprises a monitor () that displays a bird's-eye image () that includes an image of a dump truck (), a payload meter ECU () that detects the load of the dump truck (), and a controller () that switches the size of a cargo image (C) displayed over the vessel () of the dump truck () and displays this image on the monitor () on the basis of the detection result of the payload meter ECU (). In a load display device for a dump truck, a plurality of cameras are installed and the load display device monitors the periphery by using a bird's-eye image that combines images obtained by the plurality of cameras.
