A passenger conveyor diagnostic system includes a processor that stores at least one visual inspection diagnostic, and a passenger conveyor system including at least one sensor configured to capture one or both of an image and a sound. The processor applies the at least one visual inspection diagnostic to one or both of the image and the sound to generate a diagnosed status of the passenger conveyor system, and overlays the diagnosed status of the passenger conveyor system on the image.

A passenger transport system sensor network has a master unit, a signal-transferring apparatus, and a plurality of sensor nodes each having at least one sensor sensing a physical measurement variable and transferring the sensed variable to the master unit via the signal-transferring apparatus. A sensor-identifying module in the master unit determines the identity of the sensors from information, stored in a database, of: a first information type about reference measurement results to be typically provided by a particular sensor under already known conditions; a second information type about the identity of a sensor node containing the particular sensor, the sensor node having a plurality of different sensors or a plurality of identical sensors in different configurations; and/or a third information type about a configuration of a sensor node holding the particular sensor, which configuration was defined in advance. Sensor identities and installation locations can be determined in an automated manner.

There is disclosed a display device making it possible to call effective attention in a use situation where unbalanced passenger load occurs between left and right lanes of a passenger conveyor. This display device includes a first display unit (7A) positioned on the left and a second display unit (7B) positioned on the right toward the passenger conveyor at a boarding (1), a control device (20) to control the first display unit (7A) and the second display unit (7B), and passenger detection means (8A, 8B) to detect passengers stepping on the passenger conveyor. The first display unit (7A) and the second display unit (7B) display images representing information to passengers. The passengers pass between the first display unit (7A) and the second display unit (7B) and step on the passenger conveyor. The control device (20) estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means (8A, 8B), and sets an image to be displayed by the first display unit (7A) and an image to be displayed by the second display device (7B) independently, depending on the state of congestion and the state of passengers gathering on only one lane.

A method and system is discussed for detecting distances between passengers walking onto escalators and moving sidewalks or travellators and for providing alerts to the passengers when minimum social distancing between the passengers is not being maintained.

According to one embodiment, a diagnostic system includes a conveyor device first and second sensors and a diagnostic device. The conveyor device includes an endless chain having a plurality of rollers coupled at regular pitches and each fit into a bush, to circularly move between a first sprocket and a second sprocket. The first and second sensors diagonally are disposed apart from each other on a moving path of the chain, irrespective of an operating direction of the conveyor device, to detect a passage of each of the rollers of the chain. The diagnostic device measures an amount of elongation of the chain based on a first detection signal output from the first sensor and a second detection signal output from the second sensor according to movement of the chain during operation of the conveyor device.
