Abstract

A method for initiating a remote operation mode of a work machine, the method including providing the work machine with a work machine-specific safety key; receiving, at a remote control station, a notification from the work machine in response to initiating the remote operation mode of the work machine by said safety key; acknowledging the work machine as being included in a safety system of the remote control station; and configuring the remote control station to start the remote operation mode of the work machine.

acknowledging the work machine as being included in a safety system of the remote control station; and

configuring the remote control station to start the remote operation mode of the work machine.

2. The method according to claim 1, wherein at least a part of actions relating to the initiation of the remote operation mode are allowed to be taken at the remote control station only if the safety key has been returned to a predetermined safety location.

3. The method according to claim 2, wherein the safety location includes a detection device arranged to detect presence of the safety key, said detection device operating as a switch for enabling to accomplish the start of the remote operation mode of the work machine.

4. The method according to claim 2, further comprising carrying out said acknowledging of the work machine as being included in the safety system of the remote control station at the safety location by using said safety key.

5. The method according to claim 2, wherein the safety location is arranged at the remote control station.

6. The method according to claim 2, wherein the safety location is arranged at a field station locating near the operating area.

7. The method according to claim 1, wherein the safety key is provided in contact with or at least in substantial vicinity of the work machine.

8. The method according to claim 7, wherein the work machine and/or the remote control station includes a key cylinder individually configured according to said safety key.

9. The method according to claim 7, wherein the safety key includes an electrical identification unit, wherefrom identification data of the safety key can be transmitted to an identification unit of the work machine and/or an identification unit of the remote control station/field station.

10. The method according to claim 1, wherein said configuring includes one or more of the following:

including the work machine in a common safety system with one or more other work machines operating in the same operating area;

including the work machine in a common remote control system with one or more other work machines operating in the same operating area;

establishing at least one communication channel between the remote control station and the work machine;

configuring layout of a user interface of the work machine to display information about remote operating status of the work machine;

configuring layout of a user interface of the remote control station to display information about the work machine, such as by replicating the layout of the user interface of the work machine; and

enabling a takeover of the control of the work machine to be remotely operated from the remote control station.

11. The method according to claim 10, wherein, in response to the work machine being included in the safety system of the remote control station for the first time, said configuring includes displaying safety guidance on the user interface of the remote control station.

12. The method according to claim 1, wherein the work machine is a rock drilling apparatus, the method further comprising

obtaining information whether a remote operator on the remote control station is operating the work machine via a camera view captured from the operating area or from a viewpoint of the remote control station;

and

arranging a drilling pattern on the user interface of the remote control station such that orientation of the drilling pattern is adjusted according to the viewing mode selected by the remote operator.

13. The method according to claim 12, further comprising arranging a map of the operating area on the user interface of the remote control station such that orientation of the map is adjusted according to the viewing mode selected by the remote operator.

14. The method according to claim 13, wherein the remote operator is operating the work machine via a camera view captured from the work station, the method further comprising adjusting the orientation of the map on the user interface of the remote control station such that course of the work machine on the map is shown as pointing upwards on the user interface.

15. The method according to claim 1, wherein the remote control station is arranged in an active operating state or in a monitoring state, wherein the active operating state is usable in response to detecting a remote operator being present at the user interface of the remote control station.

16. The method according to claim 15, wherein moving the work machine remotely in the active operating state is only enabled by activating a manual actuator at the remote control station.

33. A computer program product, stored on a non-transitory memory medium, comprising computer program code to initiate a remote operation mode of a work machine, wherein the work machine is provided with a work machine-specific safety key, the computer program code which, when executed by a processor, causes an apparatus to:

receive a notification from the work machine in response to initiating the remote operation mode of the work machine by said safety key;

acknowledge the work machine as being included in a safety system of a remote control station; and

configure the remote control station to start the remote operation mode of the work machine.

37. The computer program product according claim 33, wherein the computer program code which, when executed by the processor, causes the apparatus to configure the remote control station by one or more of the following actions:

including the work machine in a common safety system with one or more other work machines operating in the same operating area;

including the work machine in a common remote control system with one or more other work machines operating in the same operating area;

establishing at least one communication channel between the remote control station and the work machine;

configuring layout of a user interface of the work machine to display information about remote operating status of the work machine;

configuring layout of a user interface of the remote control station to display information about the work machine, such as by replicating the layout of the user interface of the work machine; and

enabling a takeover of the control of the work machine to be remotely operated from the remote control station.
