Definitions

  • the disclosure relates to a detection method and a detection system for a person trapped in an elevator car.
  • Elevators are used more and more frequently in today's urbanization and are becoming more and more closed. However, when the building loses power, it sometimes happens that passengers are stranded in the elevator car (i.e., the elevator is trapped), which leads to an immediate negative experience for the passengers. Because this is a safety-related issue, passengers are very sensitive to it, and there are government requirements to detect stranded passengers when buildings lose power. This poses a challenge for elevator manufacturers to detect stranded passengers in a timely manner in the event of a loss of communication when the elevator controller stops operating and loses power. Of course, it is also a challenge for elevator manufacturers to detect passenger retention in a timely manner without power failure.

Abstract

L'invention concerne un procédé et un système de détection d'une personne piégée par une cabine d'ascenseur. Le procédé comprend les étapes suivantes : configuration d'un contrôleur d'ascenseur (1) d'un ascenseur pour collecter des paramètres d'état d'une cabine d'ascenseur (3) en temps réel ; configuration d'une unité de transmission numérique (2) de l'ascenseur pour acquérir en continu les paramètres d'état à partir du contrôleur d'ascenseur et stocker en continu les paramètres d'état ; lorsque l'ascenseur se trouve dans un état hors tension, détection par l'unité de transmission numérique, conformément à une combinaison logique des paramètres d'état acquis, si la cabine d'ascenseur se trouve dans un état dans lequel une personne est piégée à l'intérieur de celle-ci ; et lorsque l'ascenseur se trouve dans un état de mise hors tension, détection par l'unité de transmission numérique, conformément à une combinaison logique des paramètres d'état qui sont acquis une seconde avant que l'ascenseur ne soit mis hors tension, si la cabine d'ascenseur se trouve dans un état dans lequel une personne est piégée à l'intérieur de celle-ci. Dans le procédé, la présence ou non d'un passager dans une cabine d'ascenseur est déterminée à l'aide d'un message interne provenant d'un contrôleur d'ascenseur, de sorte qu'il n'est pas nécessaire de monter un capteur supplémentaire même si l'ascenseur est mis hors tension, et les coûts peuvent être réduits.
