A loading vehicle detects the position of a receiving vehicle relative to the loading vehicle and determines whether the receiving vehicle is to be repositioned. If so, it sends a repositioning message to the receiving vehicle and receives acknowledgement that the loading vehicle has remote control of the positioning mechanisms in the receiving vehicle. A loading vehicle operator input is detected and a position control signal is sent to the receiving vehicle to reposition it relative to the loading vehicle.

There is provided a system and the like capable of assisting remote operation of a work machine performed by a remote operator in such a way that contact between the work machine and an actual machine operator and other unfavorable situations can be avoided. Even in a situation in which a first evaluation result is affirmative and a work machine 40 can be remotely operated via a remote operation apparatus 20, but in a situation in which a second evaluation result is affirmative and it is highly probable that a worker carrying a portable terminal 60, such as an actual machine operator OP2, is so close to the work machine 40 or on the work machine 40 that short-range wireless communication between the work machine 40 and the portable terminal 60 is established, remote operation of the work machine 40 is inhibited.

A purpose of the present invention is to provide a remote operation assistance system used for assisting an operator OP in remotely operating a work machine. In order to achieve this purpose, the remote operation assistance system of the present invention includes: a distance acquisition unit 201 that obtains information on a distance from the operator OP to a moving body M; an attribute acquisition unit 202 that obtains an attribute to which the moving body M belongs; an interference determination unit 203 that determines a level of likelihood of interference occurring with the remote operation, based on the distance obtained by the distance acquisition unit 201 and the attribute obtained by the attribute acquisition unit 202; and an assistance control unit 204 that performs control to assist in the remote operation according to a result of the determination by the interference determination unit 203.

Provided is a server and a system that can assist an operator in recognizing whether or not a work machine in a work-site birds-eye image output on an output interface constituting a remote operation device is subject to remote operation by the remote operation device. According to the captured image acquired through the image pickup device C, when a work machine 40 is in the work-site birds-eye image that is output on an output interface 220 constituting a remote operation device 20, whether or not the work machine 40 is a connection-target work machine is determined. If the determination result is positive, a first sign image ID1 associated with an actual machine image Q2 that represents the work machine 40 in the work-site birds-eye image is displayed on the output interface 220 of the remote operation device 20.

A work assisting server 10 includes a first assisting process element 121 and a second assisting process element 122 and communicates with a plurality of facility cameras 30 when an operator OP remotely operates a work machine 40 while viewing a captured image displayed on an image output device 221. The first assisting process element 121 extracts, as candidates, the facility cameras 30 including the work machine 40 in imaging ranges. The second assisting process element 122 selects the facility camera 30 that is able to obtain the imaging range including an optimal direction or size on the basis of movement of the work machine 40 and causes the selected facility camera 30 to output a captured image to the image output device 221.

A controller of a work machine includes: a service request generation unit that generates and transfers information for requesting a remote service; a service execution condition management unit that confirms and manages the condition for executing the remote service; and an operating mode management unit that manages the operating mode and the operation status of the work machine. The service request generation unit generates service request information containing function types of a plurality of remote services, the operating mode of the vehicle, and the communication performance of the communication network, and transfers it to the data center. For each function type included in the service request information, the service execution condition management unit outputs service execution information containing the execution possibility, the condition for operating mode, and the condition for communication performance.

A disclosed shovel includes a hydraulic pump, a hydraulic actuator driven by hydraulic fluid supplied from the hydraulic pump, an electric motor configured to drive the hydraulic pump, a power storage device configured to be chargeable with power from an external power source to supply driving power to the electric motor, an input device configured to receive input from a user, an imaging device configured to acquire information about surroundings of the shovel, and a control device configured to set a target value of a charge amount of the power storage device, the power storage device being charged with power supplied from the external power source, in response to a predetermined input received by the input device.

A computer-implemented method for automatically adjusting a moldboard of a motor grader can include receiving one or more identifiers corresponding to a configuration of the motor grader, and determining, based on the received identifier(s), a first orientation of the moldboard. If the first orientation is not within an operating threshold, the method can further include selecting, based on the one or more identifiers, at least one of a plurality of actuators of the motor grader; and actuating the selected actuator(s) to move the moldboard from the first orientation to a second orientation within the operating threshold.

A work vehicle includes: an imaging device that captures an image in which a work target is shown; an image transmission unit that transmits the image captured by the imaging device to a control device; an operation signal reception unit that receives an operation signal from the control device; and an operation control unit that limits the operation signal according to a transmission status of the image.

In a method of making work plans for construction machinery, information of the construction machinery at a work site is obtained. The information of the construction machinery is received via a wireless communication. The information of the construction machinery is displayed on a display portion of a server. A work plan of the construction machinery is created on the display portion of the server by using the information of the construction machinery and information stored in the server. The work plan is transmitted to the construction machinery.
