摘要： 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. In response to a first designated operation through a remote input interface 210 of a remote operation device 20, a remote output interface 220 of the remote operation device 20 outputs a work environment image showing positions of designated work locations Q1 and Q2, and information about at least one of a designated work period and a designated work content. The designated work location, the designated work period and the designated work content are included in designated work information that is work information fitting a designated position depending on the first designated operation among a plurality of pieces of work information registered in a database 102.

摘要： 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.

摘要： Provided is a system which can supply appropriate information to one operator from a viewpoint that the one operator grasps a remotely operational mode for a working machine by the other operator. In a first remote operation apparatus 10, a passive mode detector 112 detects a passive mode of a first operation mechanism 111, and transmits operational mode data corresponding to the passive mode. In a second remote operation apparatus 20, an operation of an actuator 212 is controlled in accordance with the passive mode of the first operation mechanism 111 in response to the operational mode data, and thereby, a second operation mechanism 211 actively operates.

摘要： A first operation mechanism 3 includes a first driving source 30 which generates a driving force based on a drive command and a first driving mechanism 32 which inclines a left-side traveling pedal 1c by the driving force from the first driving source 30. The first driving mechanism 32 has a first abutting portion 32a which abuts a pedal surface of the left-side traveling pedal 1c and a first driving unit 32b which inclines the left-side traveling pedal 1c by inclining the first abutting portion. The first driving unit 32b is arranged in a position shifted to a lateral side from a space in which the first abutting portion 32a moves.

摘要： A master-side device is provided outside a working machine and transmits, to a slave-side device, a command for controlling activation of an actuator. The master-side device is provided with a master-side lever and an operation pattern switching unit. The operation pattern switching unit switches a master-side operation pattern in which a first command according to an operation of the master-side lever is combined with a second command for an operation of a machine-side lever. The slave-side device transmits, to the master-side device, information of a machine-side operation pattern selected by an operation pattern switching valve.

摘要： A remote operation system for a working machine includes a control device enabling an operator wearing a wearable display to grasp the surrounding situation of himself/herself. The control device includes an operation intention judgment section judging the presence/absence of an operator's operation intention to a remote operation lever based on the contents of acquired judgment information, and a display image switching section. With judgment of presence of the operation intention, the display image switching section makes a working area image taken by a working area image taking camera be displayed in a particular display area of the wearable display. With judgment of absence of the operation intention, the display image switching section stops the display of the working area image in the at least a part of the particular display area and switches it to a surrounding visual-recognition allowing area allowing the operator to visually recognize the surroundings.

摘要： A correction value for matching an operation characteristic of a slave operating device with an operation characteristic of a master operating device is registered in advance in a correction table for each combination of type information of a construction machine and type information of the slave operating device. A controller acquires, from correction information, a correction value corresponding to a combination of the type information of the construction machine and the type information of the slave operating device received by a communication unit, corrects an amount of operation accepted by an operating lever based on the acquired correction value, and transmits the corrected amount of operation to the communication unit.
