Method and device for monitoring the drive operation of a passenger conveyor system

A method for monitoring a drive operation of a passenger conveyor system with a monitoring system, wherein the monitoring system comprises a hazard analysis module, an interaction module, a control module and at least one movement detection module, wherein the at least one movement detection module is directed toward an associated passenger conveyor system and is configured to record electronically processable movement sequence images of situations that occur on the associated passenger conveyor system, the method comprising:

• transmitting the electronically processable movement sequence images in real time to the hazard analysis module and performing an analysis therein as to whether there is a critical situation for users of the passenger conveyor system in the electronically processable movement sequence images;
• generating, with the hazard analysis module, a warning signal when a critical situation occurs in the electronically processable movement sequence images;
• sending the warning signal to the interaction module and the control module and displaying on a screen of the interaction module the electronically processable movement sequence image correlating with the warning signal after receipt of the warning signal;
• initiating, with the control module, a change in the drive operation of the passenger conveyor system associated with the warning signal;
• activating, with the interaction module, an input device of the monitoring system;
• and
• instructing the control module to suppress or cancel the change in the drive operation initiated by the warning signal upon manual operation of the input device.
