Abstract

A remote monitoring system for an elevator system includes at least one remotely operable intermediate device and a monitoring unit for remotely controlling operation of the at least one intermediate device at least partly. The monitoring unit controls at least one intermediate device to generate a remote command for controlling at least one operation of the elevator system, and monitors a response of the elevator system to the remote command. A method for remotely monitoring an elevator system is also included.

First claim

The invention claimed is:

1. A remote monitoring system for an elevator system, comprising:
at least one remotely operable intermediate device, and
a monitoring unit for remotely controlling operation of the at least one remotely operable intermediate device, wherein the monitoring unit is configured to
control the at least one remotely operable intermediate device to generate a remote command for controlling at least one operation of the elevator system, and
monitor a response of the elevator system to the remote command,
wherein the at least one remotely operable intermediate device is electrically connected to terminals of a switch of an elevator button and is configured to electrically connect the terminals to each other.

2. The remote monitoring system according to claim 1 , wherein the monitoring unit is further configured to define whether the elevator system has responded to the remote command in an expected manner.

3. The remote monitoring system according to claim 2 , wherein the monitoring unit is further configured to generate a signal indicating that the elevator system is out of service to an external computing entity, in response to detection that the elevator system is not responding to the remote command in the expected manner.

4. A remote monitoring system for an elevator system, comprising:
at least one remotely operable intermediate device, and
a monitoring unit for remotely controlling operation of the at least one remotely operable intermediate device, wherein the monitoring unit is configured to
control the at least one remotely operable intermediate device to generate a remote command for controlling at least one operation of the elevator system, and
monitor a response of the elevator system to the remote command,

wherein the monitoring unit is configured to provide a monitored response to an external computing entity, and the external computing entity is configured to define whether the elevator system is responding to the remote command in an expected manner based on the monitored response.

5. The remote monitoring system according to claim 1 , wherein the monitoring unit is configured to control the at least one remotely operable intermediate device in response to receiving an instruction from an external computing entity.

6. The remote monitoring system according to claim 3 , wherein the external computing entity comprises one of a cloud server, a service center, and a data center.

7. The remote monitoring system according to claim 1 , wherein the remote command is a remote elevator command, wherein the remote elevator command is a landing call, destination call, or a car call, and the at least one operation of the elevator system is movement of an elevator car.

8. The remote monitoring system according to claim 1 , wherein the remote command is a remote elevator command, wherein the remote elevator command is one of an emergency call, an elevator alarm, and an opening or closing command of an elevator door, and a corresponding operation of the elevator system is one of making of an emergency call, generating an elevator alarm, and opening or closing an elevator door.

9. The remote monitoring system according to claim 1 , wherein the remote command is a remote maintenance command and the at least one operation of the elevator system is a maintenance operation.

10. The remote monitoring system according to claim 1 , wherein the at least one remotely operable intermediate device is retrofittable to an existing elevator system.

11. The remote monitoring system according to claim 1 , wherein the remote command generated by the at least one remotely operable intermediate device corresponds to a command generated in response to an activation of an elevator button.

12. The remote monitoring system according to claim 1 , wherein the at least one remotely operable intermediate device comprises a switching device configured to bridge the terminals of the switch of the elevator button.

13. The remote monitoring system according to claim 12 , wherein the switching device is configured to create an electric connection between the terminals of the switch of the elevator button to short-circuit the switch of the elevator button to generate a command corresponding to a command generated in response to an activation of the elevator button.

14. The remote monitoring system according to claim 1 , wherein the monitoring unit is a retrofittable monitoring unit arranged to an existing elevator system and is independent of an elevator control system of the elevator system.

15. A method of remotely monitoring an elevator system, the method comprising:
controlling at least one remotely operable intermediate device to generate a remote command for controlling at least one operation of the elevator system,
monitoring a response of the elevator system to the remote command,
providing a monitored response to an external computing entity, and
determining at the external computing entity whether the elevator system is responding to the remote command in an expected manner based on the monitored response.

16. The method of remotely monitoring an elevator system according to claim 15 , wherein the external computing entity comprises one of a cloud server, a service center, and a data center.

17. The remote monitoring system according to claim 1 , wherein the elevator button comprises an elevator user interface button of a car operating panel in an elevator of the elevator system.

18. The remote monitoring system according to claim 1 , wherein the elevator button comprises an elevator user interface button of a landing call panel at a landing outside an elevator of the elevator system.

19. The remote monitoring system according to claim 1 , wherein the elevator button comprises a maintenance control button of an inspection drive station of the elevator system.
