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.

Remote operation assistance device and remote operation assistance method

A remote operation assistance device enables an operator to get a feel for the controls of a work machine before communication is established between a remote operation device and the work machine. The remote operation assistance device as configured includes a first assistance processing element. The first assistance processing element executes a control for displaying, on a remote output interface, a simulated environment image for simulating remote operation of the work machine.

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.

Image processing device and image processing method

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

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 machineis in a first state (an operable state), a display magnification of a captured image (environment image) outputted to a remote output interfaceis 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 machineis in a second state (an inoperable state), a zoom function of an actual machine image capturing deviceis demonstrated according to a zoom operation through a remote input interfaceby the operator.

Remote operation support system and remote operation support method

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 switchfrom off to on, a first power supply route from an actual machine power sourceto an actual machine control deviceis formed. Consequently, a second power supply route from the actual machine power sourceto the actual machine control deviceis formed. Then, the first power supply route is cut off, while the second power supply route not through the actual machine switchis maintained.

Work machine and remote operation support system

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.

Display system for work machine

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.
