  • Publication number: 20220106765
    Abstract: There is provided a device that enables an operator of a work machine to recognize whether or not an object exists in the periphery of the work machine with an appropriate amount of information from the viewpoint of avoiding a reduction in focus of the operator of the work machine. When the state of operation of an operation device 400 performed by an operator is a “first operation state”, and an object exists in a target space around a work machine 200, an alarm is output in a “first mode”. When the state of operation of the operation device 400 performed by the operator is a “second operation state”, and an object exists in the target space around the work machine 200, an alarm is output in a “second mode” in which a larger amount of information is provided than in the “first mode”.

  • Publication number: 20220064909
    Abstract: A periphery monitoring apparatus for a work machine determines at least one part of a plurality of target spaces as a “first designated target space”, according to an action mode of the work machine, which is predicted on the basis of an operation state by the operator of an operating device of the work machine. When a position of the object is included in the first designated target space, an alarm is output by the first designated output device that is arranged in an azimuth corresponding to an azimuth of the first designated target space with reference to the work machine, with reference to a location of the operator in a driving space of the work machine. The alarm is differentiated according to a varying mode of a relative position between the work machine and the object.

  • Publication number: 20220004166
    Abstract: 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.

  • Publication number: 20210079621
    Abstract: 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.
