Abstract

A method for automated monitoring of a passenger transport system with a monitoring system. The monitoring system has a hazard analysis module and a motion-sensing module. The motion-sensing module is configured to capture real motion sequence recordings. The method comprises: receiving real motion sequence recordings and data of a digital double of the passenger transport system in the hazard analysis module, wherein the data comprise information relating to physical properties of the passenger transport system, which allow determination of a visual appearance of the passenger transport system; determining dynamic objects information on the passenger transport system with the hazard analysis module based on the received recordings and data; determining a current hazardous situation on the passenger transport system with the hazard analysis module based on an analysis of the determined dynamic objects; and outputting a warning with the hazard analysis module based on the current hazardous situation.

First claim

1 - 13 . (canceled)

14 . A method for automated monitoring of a travel operation of a passenger transport system with a monitoring system, wherein the monitoring system comprises a hazard analysis module and at least one motion-sensing module, wherein the at least one motion-sensing module is directed toward the passenger transport system and is configured to capture electronically processable real motion sequence recordings of situations which occur on the passenger transport system, the method comprising:
receiving real motion sequence recordings in the hazard analysis module, wherein the real motion sequence recordings have been captured by the at least one motion-sensing module; receiving data of a digital double of the passenger transport system in the hazard analysis module, wherein the data comprise at least information relating to physical properties of the passenger transport system which are used to determine a visual appearance of the passenger transport system in a predetermined motion state; determining object information relating to dynamic objects on the passenger transport system by the hazard analysis module, wherein the information is determined based on the data of the digital double received and the real motion sequence recordings; determining hazard information relating to a current hazardous situation on the passenger transport system by the hazard analysis module based on an analysis of motions of the dynamic objects determined; and outputting a warning by the hazard analysis module based on the hazard information determined relating to the current hazardous situation.

15 . The method of claim 14 , wherein virtual motion sequence recordings are determined by the hazard analysis module on the basis of the data of the digital double received, and wherein the object information relating to the dynamic objects on the passenger transport system is determined by the hazard analysis module by comparing the virtual motion sequence recordings with the real motion sequence recordings.

16 . The method of claim 15 , wherein comparing the virtual motion sequence recordings with the real motion sequence recordings is carried out by forming a difference between the real motion sequence recordings and the virtual motion sequence recordings.

17 . The method of claim 15 , wherein the method further comprises synchronizing the real motion sequence recordings with the virtual motion sequence recordings such that movable components of the passenger transport system are in an identical motion state in both motion sequence recordings.

18 . The method of claim 16 , wherein the method further comprises synchronizing the real motion sequence recordings with the virtual motion sequence recordings such that movable components of the passenger transport system are in an identical motion state in both motion sequence recordings.

19 . The method of claim 17 , wherein synchronizing takes place taking into account data which are received from a controller of the passenger transport system and which contain motion information about an actual current motion state of the passenger transport system.

20 . The method of claim 17 , wherein synchronizing is carried out taking into account speed information of a frequency converter of the passenger transport system or a signal of an encoder arranged on the passenger transport system.

21 . The method of claim 19 , wherein synchronizing is carried out taking into account speed information of a frequency converter of the passenger transport system or a signal of an encoder arranged on the passenger transport system.

22 . The method of claim 17 , wherein synchronizing is carried out taking into account moving position information, wherein the moving position information is determined by observing a marking which is fixed at a location of a movable component of the passenger transport system and is moved along by it.

23 . The method of claim 19 , wherein synchronizing is carried out taking into account moving position information, wherein the moving position information is determined by observing a marking which is fixed at a location of a movable component of the passenger transport system and is moved along by it.

24 . The method of claim 14 , wherein a comparison of the motions of the dynamic objects determined with stored motion scenarios which represent potential hazardous situations is carried out in order to analyze the motions of the dynamic objects determined.

25 . The method of claim 15 , wherein a comparison of the motions of the dynamic objects determined with stored motion scenarios which represent potential hazardous situations is carried out in order to analyze the motions of the dynamic objects determined.

26 . The method of claim 14 , wherein the current hazardous situation on the passenger transport system is evaluated based on a comparison of the dynamic objects determined with various stored motion scenarios, and wherein the warning is output depending on the evaluation of the hazardous situation.

27 . The method of claim 15 , wherein the current hazardous situation on the passenger transport system is evaluated based on a comparison of the dynamic objects determined with various stored motion scenarios, and wherein the warning is output depending on the evaluation of the hazardous situation.

28 . A monitoring system for monitoring travel operation of a passenger transport system, wherein the monitoring system comprises a hazard analysis module which is configured to receive data from a motion-sensing module and from a database module, wherein the motion-sensing module is directed toward the passenger transport system and is configured to capture electronically processable real motion sequence recordings of situations which occur on the passenger transport system, and wherein data of a digital double of the passenger transport system are stored in the database module, wherein the data comprise at least information relating to physical properties of the passenger transport system which are used to determine a visual appearance of the passenger transport system in a predetermined motion state, wherein the hazard analysis module is configured to carry out or control the method of claim 14 .

29 . A passenger transport system, comprising:
a transport belt; a drive for driving the transport belt; a controller for controlling the drive; the monitoring system of claim 28 , wherein the motion-sensing module is directed at least toward partial regions of the transport belt.

30 . A computer program product, comprising machine-readable program instructions which, when executed on a programmable device, causes a device to carry out or control the method of claim 14 .

31 . A computer program product, comprising machine-readable program instructions which, when executed on a programmable device, causes a device to carry out or control the method of claim 15 .

32 . A computer program product, comprising machine-readable program instructions which, when executed on a programmable device, causes a device to carry out or control the method of claim 16 .

33 . A computer-readable medium comprising the computer program product of claim 30 stored thereon.
