With respect to any one of the plurality of construction machines 10, the server 50 is configured to, when acquiring information indicating occurrence of the predetermined event associated with the construction machine, output report information indicating the occurrence from the reporting devices 44, 45.

A method for automatically controlling an operation of a work vehicle during the performance of an earthmoving operation may include receiving an input associated with initiating an automated dumping operation to allow a load of worksite materials contained by an implement of a lift assembly of the work vehicle to be released onto a dump pile. The method may further include determining a current vertical height of the dump pile based on data from at least one sensor and determining a dumping height of the implement for performing the dumping operation based on the current vertical height. Additionally, the method may include controlling an operation of the lift assembly to move the implement to the dumping height and then to pivot the implement from a load-carrying position to a load-dumping position to release the load of worksite materials onto the dump pile from the dumping height.

A computer-implemented method for controlling an excavation task by an autonomous excavation vehicle comprising a scanning device, the excavation task being described by a target map, the method comprising using an excavation vehicle control system for: a) according to data from the scanning device, maintaining a map representing current terrain; b) moving a sensor-equipped digging implement for executing an excavation operation; c) receiving data indicative of current terrain topography from the sensor; d) updating the maintained map according to the data indicative of current terrain topography; and e) calculating an excavation operation according to the difference between the maintained map and the target map.

Provided are a server and system which allow a plurality of people involved in work to share information about an object requiring attention in a work area. A work environment image, which indicates an extension mode of a target object in a real space in a target object image region R that is a part of a captured image obtained through an imaging device (e.g., an imaging device 612) of a first client (e.g., a worker terminal 60) and target object related information, is outputted to an output interface (e.g., a remote output interface 220) of a second client (e.g., a remote operation device 20).

A remote starting system and method are provided for self-propelled work vehicles having work attachments supported from a main frame thereof. Cameras are arranged with respective fields of vision proximate to the work vehicle, and a communications unit is configured to exchange messages with a user device via a communications network. A local or remote controller is configured to receive first user input comprising a remote startup request for the work vehicle from the user device, and to automatically detect parameters respectively associated with predetermined remote startup conditions, at least one of the parameters comprising images obtained from the cameras. The images are transmitted to the user device, responsive to which second user input is received comprising remote startup confirmation from the user device via the communications network. Responsive to at least the second user input, engine startup is automatically controlled for the work vehicle.

The transport vehicle position estimating device includes: a distance image acquiring part for acquiring a distance image of a box bed; and a calculation part. The calculation part sets a box bed scope indicative of a positional extent of the box bed on the basis of the distance image of the box bed acquired by the distance image acquiring part. The calculation part acquires a dischargeable region indicative of a dischargeable extent of the attachment under the condition that the attachment is operated but the lower travelling body is not travelled. The calculation part determines whether the box bed scope falls within the dischargeable region.

In an overturning-risk presentation device according to the present invention, a reception unit is configured to receive posture data of a work machine of a time when the work machine detects an overturning risk. A calculation unit configured to calculate the number of times of detection of the overturning risk for each inclination direction of the work machine based on the posture data. A generation unit configured to generate an inclination frequency image representing the number of times of detection of the overturning risk for each inclination direction of the work machine. An output unit configured to output the generated inclination frequency image.

Provided are a server and a system which enable a worker of a work machine to intuitively recognize work contents and the like to be performed using the work machine in each of a plurality of work locations.
