This application relates to a method and an apparatus for monitoring a state of a passenger transport system such as, for example, an escalator. The method includes monitoring the state of the passenger transport system using an updated digital double data record that reflects characterizing properties of components of the passenger transport system in an actual configuration of the passenger transport system in a machine-processable manner after the assembly and installation thereof in a building. The updated digital double data record can be obtained, for example, by accurately surveying the passenger transport system and using signal values from sensors housed in the passenger transport system, and allows conclusions as to the present or future state of the passenger transport system, based on which maintenance measures can be planned efficiently and adequately.

A transport-monitoring module for monitoring a transport of a transport unit of a passenger-transportation device is arranged on the transport unit. The transport-monitoring module has a sensor and localization devices. During the transport, through an interface unit, a connection with a data memory of the device is created. The interface unit is configured so that transport-monitoring data that are to be stored, which are based on sensor data of the sensor and localization data of the localization devices, are permanently stored in the data memory. In this way, the transport-monitoring module is simplified, so that it is no longer an item that is worth stealing. In addition, a reliable access to the stored transport-monitoring data after the end of the transport is secured.

A monitoring system for a passenger conveyor is provided. The passenger conveyor includes a motor for driving the passenger conveyor and an inverter for supplying current to the motor. The monitoring system includes a current sensor for detecting the current supplied to the motor; a temperature sensor for detecting the temperature of the motor; a data collecting device for receiving detected data from the current sensor and the temperature sensor; and a controller connected to the data collecting device. The controller is configured to calculate an idle operation motor torque during an idle operation of the passenger conveyor based on current and temperature detected during the idle operation; and determine that a fault exists in the passenger conveyor when a difference between the idle operation motor torque and a reference motor torque exceeds a predetermined threshold.

An escalator equipment alert method and an escalator equipment alert system are disclosed. The method includes: activating a camera disposed on an entrance of an escalator equipment; capturing a foot image of a passenger about to board the escalator equipment through the camera; performing an image analyzation on the foot image to detect a danger boarding behavior related to the passenger; and in response to the danger boarding behavior, issuing an alert message matched with the danger boarding behavior through an alert device.
