Abstract

A method remotely recovers at least one peripheral device of a people conveyor system. The method includes controlling at least one network element, into which the at least one peripheral device is connected, to control power supply of the at least one peripheral device to remotely recover the at least one peripheral device. The invention relates also to a remote monitoring unit and a remote monitoring system for remotely recovering at least one peripheral device of a people conveyor system.

First claim

The invention claimed is:

1. A method for remotely recovering at least one peripheral device of a people conveyor system, the method comprises
determining, by at least one network element into which at least one peripheral device is connected, that the at least one peripheral device is unresponsive based on the at least one network element not detecting a response to a status query or recovery attempt sent to the peripheral device for a predetermined time; and
controlling the at least one network element to control power supply of the at least one peripheral device to remotely recover the at least one peripheral device in response to the at least one peripheral device being unresponsive.

2. The method according to claim 1 , the controlling of the at least one network element is performed in response to detecting that the at least one peripheral device is unresponsive.

3. The method according to claim 2 , wherein power supply of the at least one peripheral device of the people conveyor system is provided via one or more data lines.

4. The method according to claim 2 , wherein the controlling of the at least one network element to control power supply of the at least one peripheral device comprises power cycling the at least one peripheral device.

5. The method according to claim 1 , wherein power supply of the at least one peripheral device of the people conveyor system is provided via one or more data lines.

6. The method according to claim 5 , wherein the power supply of the at least one peripheral device of the people conveyor system is provided by using Power over Ethernet (POE).

7. The method according to claim 5 , wherein the controlling of the at least one network element to control power supply of the at least one peripheral device comprises power cycling the at least one peripheral device.

8. The method according to claim 1 , wherein the controlling of the at least one network element to control power supply of the at least one peripheral device comprises power cycling the at least one peripheral device.

9. The method according to claim 8 , wherein the controlling of the at least one network element to power cycle the at least one peripheral device comprises:
generating to the at least one network element a first control request comprising an instruction to power down the at least one peripheral device, and generating to the at least one network element a second control request comprising an instruction to power up the at least one peripheral device.

10. The method according to claim 1 , further comprising:
generating a status query to the at least one peripheral device, and defining a successful recovery of the at least one peripheral device in response to receiving a status response from the at least one peripheral device.

11. The method according to claim 1 , wherein the people conveyor system is an elevator system, an escalator system, or a moving walkaway system.

12. A remote monitoring unit for remotely recovering at least one peripheral device of a people conveyor system, the remote monitoring unit comprising:
a processing unit, and
a memory unit for storing at least one portion of computer program code,
wherein the processing unit being configured to cause the remote monitoring unit at least to control at least one network element, into which the at least one peripheral device is connected, determine that the at least one peripheral device is unresponsive based on the at least one network element not detecting a response to a status query or recovery attempt sent to the peripheral device for a predetermined time, and to control power supply of the at least one peripheral device to remote recover the at least one peripheral device in response to the at least one peripheral device being unresponsive.

13. The remote monitoring unit according to claim 12 , wherein the control of the one at least one network element is performed in response to detecting that the at least one peripheral device is unresponsive.

14. The remote monitoring unit according to claim 12 , wherein power supply of the at least one peripheral device of the people conveyor system is provided via one or more data lines.

15. The remote monitoring unit according to claim 14 , wherein the power supply of the at least one peripheral device of the people conveyor system is provided by using Power over Ethernet (POE).

16. The remote monitoring unit according to claim 12 , wherein the control of the at least one network element to control power supply of the at least one peripheral device comprises power cycling the at least one peripheral device.

17. The remote monitoring unit according to claim 16 , wherein the control of the at least one network element to power cycle the at least one peripheral device comprises:
generation of a first control request comprising an instruction to power down the at least one peripheral device to the at least one network element, and generation of a second control request comprising an instruction to power up the at least one peripheral device to the at least one network element.

18. The remote monitoring unit according to claim 12 , further configured to:
generate a status query to the at least one peripheral device, and define a successful recovery of the at least one peripheral device in response to receiving a status response from the at least one peripheral device.

19. The remote monitoring unit according to claim 12 , wherein the people conveyor system is an elevator system, an escalator system, or a moving walkaway system.

20. A remote monitoring system for remotely recovering at least one peripheral device of a people conveyor system, the remote monitoring system comprising:
at least one network element, into which the at least one peripheral device is connected, and a remote monitoring unit according to claim 9 .
