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 (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 monitored escalator barricade system is disclosed herein having a barricade assembly including a hosting column supporting a one-way swinging door and a magnetic locking mechanism. The barricade assembly is installable at a landing floor and allows for one-way passage of a user riding along an outer edge of an escalator in order to prevent injuries. The barricade assembly utilizes IR beam transmitters on an exterior of the hosting column to detect when a user arrives near the landing floor and unlock the one-way swinging door as the user approaches. The monitored escalator barricade system includes various visual and audio indicators for notifying authorities.

The present invention discloses an escalator monitoring system, which includes a data collection device disposed near the parts of the escalator that require monitoring in order to collect data the parts relevant to the operation of the escalator, a data transmittal device used to send the collected data, a cloud processor used to receive the data, to compare the data against threshold data of the parts obtained under normal operating conditions stored in the database of the cloud processor, and to respond based on the comparison result. The present invention can collect the data and analyze it in any environment independent of subjective human judgment, predict possible failure without the need to stop the operation of the escalator, save maintenance time, reduce associated cost, and thus improve its safety and ride comfort.

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.
