摘要： When a remote operation of a work machine 40 through one remote operation apparatus 20 as a first remote operation apparatus is stopped by one operator, operation of an engine 460 of the work machine 40 is continued without being stopped if another operator who may possibly continuously remotely operate the same work machine 40 through another remote operation apparatus 20 as a second remote operation apparatus exists. Therefore, the other operator can immediately remotely operate the work machine 40 through the second remote operation apparatus without causing the engine 460 of the work machine 40, which has been an operation target of the first remote operation apparatus so far, to restart and perform warm-up operation.

摘要： 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.

摘要： Provided are a server and a system which enable one operator driving or operating a work machine to intuitively recognize advice or instruction from another operator. A route guidance request from a first work machine 40 cooperating a first client (first remote operation device 20) is accepted. A guided route R extending between a first designated position P1 and a second designated position P2 may be designated through an input interface 210 of a second client (second remote operation device 20). Then, route guidance information depending on the guided route R is outputted to an output interface 220 of the first client.

摘要： A display device 20 includes: a hinge 91; a first monitor device 21 including a first front surface 22; and a second monitor device 31 including a second front surface 32. Parallel planes from a virtual second front surface on a rear side by predetermined distances at a first angle a to a third angle c between the first front surface 22 and the virtual second front surface are defined as first to third virtual planes E to G. A rotation axis X1 of the hinge 91 is disposed on anyone of these three virtual planes or inside a space formed by the three virtual planes in a view in a direction parallel to the rotation axis X1, and the second front surface 32 is disposed at a position away from the rotation axis X1 on a front side of the second monitor device 31 by a predetermined distance.
