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 machineis in the work-site birds-eye image that is output on an output interfaceconstituting a remote operation device, whether or not the work machineis a connection-target work machine is determined. If the determination result is positive, a first sign image IDassociated with an actual machine image Qthat represents the work machinein the work-site birds-eye image is displayed on the output interfaceof the remote operation device

Work assist server, work assist method, and work assist system

A server causes an information terminal device to display a selection image for allowing an operator to select a desired operation among one or more operations and a desired master device among one or more master devices based on operation request information stored in a first database and master device information stored in a second database. The information terminal device sends to the server a selection instruction of the operator who selects the desired operation and the desired master device via the selection image. The server receives an operation order acceptance of the operator by storing, in an operation plan database, an operator ID, a master device ID and the operation designated by the selection instruction in combination with one another.

Job selection system and job selection method

According to the remote operation system or a remote operation serverincluded in the remote operation system, a 'communication resource allocation process' is performed according to the skill or the like of the operator to allocate communication resources to a plurality of remote operation devices. When the “environment information control process” is performed, a data amount of environment data is reduced such that a reduction in the information amount of one or a plurality of low environment information factors is greater than the reduction in the information amount of one or a plurality of high environment information factors (meaning the reduction in the information amount of the environment information due to a change in the environment information factor). The environment information control process is performed in different modes according to a difference in an allocation resource.

Remote operation system and remote operation server

According to the remote operation system or a remote operation serverincluded in the remote operation system, when the 'environment information control process' is performed, a data amount of environment data is reduced such that the reduction in the information amount of one or a plurality of low environment information factors is greater than the reduction in the information amount of one or a plurality of high environment information factors (meaning the reduction in the information amount of the environment information due to a change in the environment information factor). The environment information control process is performed by classifying the environment information factors into the high environment information factor and the low environment information factor according to a difference in the operation state.

A construction machine capable of suppressing deterioration in work efficiency includes an angle detecting device that detects a relative angle between a lower travelling body and an upper slewing body, a travel lever that can be manipulated to make the lower travelling body travel, a display, a directional information generating unit that generates information related to a travelling direction of the lower travelling body based on a detected result of the angle detecting device, and a display controller. The display controller causes the display to display an arrow image indicating the travelling direction of the lower travelling body generated by the directional information generating unit when the travel lever is manipulated and does not permit the display to display the arrow image when the travel lever is not manipulated.

Construction machine

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 machinecan be remotely operated via a remote operation apparatus, but in a situation in which a second evaluation result is affirmative and it is highly probable that a worker carrying a portable terminal, such as an actual machine operator OP, is so close to the work machineor on the work machinethat short-range wireless communication between the work machineand the portable terminalis established, remote operation of the work machineis inhibited.

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

There is provided a server and a system capable of enabling an operator of a remote operating device to recognize which remote operating device remotely operates a work machine displayed on an output interface constituting the remote operating device. For example, a first work environment image indicating a situation of a work site acquired through an image pickup deviceloaded on a work machineis outputted on an output interfaceconstituting each of a plurality of remote operating devices

Work assisting server and work assisting system

A first operating mechanismof a work machineincludes a first guide memberwhich tilts a fourth operating leverin the right-left direction, and a first actuatorwhich generates a driving force for tilting a first direction guide memberon the basis of an operation command. The first actuatoris disposed at a position on the opposite side of the fourth operating leverfrom a slave-side seat
