Abstract: Provided is a work machine or the like which can switch between a power supply state and a power supply cutoff state of an actual machine control device irrespective of switching on or off an actual machine switch. On switching an actual machine switch 81 from off to on, a first power supply route from an actual machine power source 80 to an actual machine control device 400 is formed. Consequently, a second power supply route from the actual machine power source 80 to the actual machine control device 400 is formed. Then, the first power supply route is cut off, while the second power supply route not through the actual machine switch 81 is maintained.

Abstract: A remote operation assistance device configured such that when an operator performs work through remote operation of a work machine, the remote operation assistance device moves the work machine to the position suitable for the work scheduled to be performed by the work machine in advance or changes the attitude of the work machine in advance so as to be suitable for the work. The present invention comprises a first assistance processing element configured to execute a first assistance process that is a process of acquiring schedule information from a database, determining based on the schedule information whether or not a preparation condition is satisfied, and transmitting, when the determination is affirmative, a preparation signal that is a control signal.

Abstract: An image of a work attachment (operation mechanism) of a work machine and the periphery of the work attachment, which corresponds to captured image data acquired by an imaging device, is displayed on an image output device by means of a first communication mode established between a slave control device mounted in the work machine and a master control device. When the first communication mode is interrupted, instead of the image of the operation mechanism of the work machine and the periphery of the operation mechanism, a point cloud image corresponding to distance image data acquired by a distance sensor is displayed on the image output device by means of a second communication mode established between the slave control device and the master control device.

Abstract: On detection of a difference between the operation amount detected by a first sensor and the operation amount received by a first communication unit from a slave, a master side controller executes at least one of stop control to automatically stop a construction machine and alarm control to cause a warning device to issue an alarm. On detection of a difference between the operation amount detected by a second sensor and the operation amount received by a communication unit from the master, a slave side controller executes at least one of the stop control to automatically stop the construction machine and the alarm control to cause the warning device to issue the alarm.

Abstract: A device or the like capable of improving continuity of a moving image outputted to an image output device of a remote operation device even in circumstances where an inter-frame difference of the moving image becomes large. When it is predicted that a data amount of a captured image is to exceed a threshold in consideration of a detection result of a moving mode of a working machine, high frequency components exceeding a specified frequency in a second specified image area excluding a first specified image area of the captured image are eliminated Thus, the data amount of the captured image is reduced so that the data amount becomes equal to or smaller than the threshold. Then, not only inter-frame continuity of the first specified image area of an environment image outputted to an image output device of a remote operation device but also visibility by an operator is improved.

Abstract: A lever drive control unit 27a of a hydraulic work machine 10 performs actuation control on a lever drive actuator 21 so as to operate an operation lever 20 to a neutral position and operation positions for a maximum operation amount and stores control values for the lever drive actuator 21 at the respective operation positions, upon receipt of a request for execution of a process in a calibration mode. The lever drive control unit 27a uses the stored control values to create data prescribing a relation between a drive command for the operation lever 20 and a control value for the lever drive actuator 21.

Abstract: An objective is to provide a remote operation assistance device 100 enabling an operator to get a feel for the controls of a work machine 40 before communication is established between a remote operation device 20 and the work machine 40. To achieve the objective, the remote operation assistance device 100 as configured includes a first assistance processing element 101. The first assistance processing element 101 executes a control for displaying, on a remote output interface 220, a simulated environment image for simulating remote operation of the work machine 40.

Abstract: 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.

Abstract: A system or the like capable of improving convenience of recognizing a surrounding situation of a working machine for an operator by controlling an image capturing function of an actual machine image capturing device in an appropriate manner in consideration of a state of the working machine is provided. When a working machine 40 is in the first state, an operation of a panning switch SW1 and a tilting switch SW2 is stopped, a posture ? of the actual machine image capturing device 412 when the operation is restarted is limited to an initial posture ?0. When the working machine 40 is in the second state, after the operation of the panning switch SW1 and the tilting switch SW2 is stopped, the posture ? of the actual machine image capturing device 412 when the operation is restarted is the posture ? as it is when the operation is stopped.

Abstract: A system or the like capable of making an operator recognize an environment around a working machine in an appropriate form in consideration of a state of the working machine. In the case where a working machine 40 is in a first state (an operable state), a display magnification of a captured image (environment image) outputted to a remote output interface 220 is controlled only in a range of a specified display magnification or lower, or is fixed at a value of the specified display magnification or lower. On the other hand, in the case where the working machine 40 is in a second state (an inoperable state), a zoom function of an actual machine image capturing device 412 is demonstrated according to a zoom operation through a remote input interface 210 by the operator.

Abstract: Provided is a work machine or the like which can switch between a power supply state and a power supply cutoff state of an actual machine control device irrespective of switching on or off an actual machine switch. On switching an actual machine switch 81 from off to on, a first power supply route from an actual machine power source 80 to an actual machine control device 400 is formed. Consequently, a second power supply route from the actual machine power source 80 to the actual machine control device 400 is formed. Then, the first power supply route is cut off, while the second power supply route not through the actual machine switch 81 is maintained.

Abstract: A work device includes, at a tip, one of different types of tip attachments that are replaceable with each other. A camera can capture an image within a movable range of the tip attachment. The work device posture sensor detects the posture of the work device. A controller sets a detection frame that is a frame of a range including the tip attachment in the image captured by the camera based on the posture of the work device detected by the work device posture sensor. The controller discriminates the type of the tip attachment based on the image of the tip attachment within the detection frame.
