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.
