Method and device for monitoring a passenger transport system using a detection device and a digital double

A method for monitoring a state of a physical passenger transport system using an updated digital-double dataset UDDD which comprises characterizing properties of components of the physical passenger transport system in a machine-processable manner, wherein:

• the UDDD is assembled from component model datasets that comprise data which were determined by measuring characterizing properties on the physical passenger transport system after it was assembled and installed in a structure;
• the physical passenger transport system comprises a continuously arranged conveyor belt including at least one escalator step or pallet with a detection device, configured to detect accelerations and changes in position detected in all three axes during operation of the physical passenger transport system and output the detected accelerations and changes in position as measurement data;
• said measurement data are transmitted to the UDDD;
• with dynamic simulations, forces, impulses and vibrations resulting from the measurement data, which act on the virtual components of the virtual conveyor belt, corresponding to the physical components, and on the virtual components which interact with the virtual conveyor belt, can be determined and evaluated using the UDDD.
