Abstract: A safety monitoring device of an elevator system having a shaft extending over at least two floors has a safety circuit with door contact switches being closed or opened accordingly when a respective shaft door is closed or opened. The door switches form an electrical series circuit that is electrically broken to block the elevator car from moving when any of the door switches is opened. The monitoring apparatus has at least one bypass switch that actuates a first door switch for a first shaft door on a first floor such that, when the elevator car reaches the first floor, the bypass switch bypasses the first door switch to switch the safety circuit independently of the first door switch. A monitoring means of the monitoring apparatus monitors the switching state of the safety circuit and/or of a second door switch for a second shaft door on a second floor.

Abstract: A method for determining a mapping of a number of floors to be served by an elevator includes the steps of: (a) determining, during a multiplicity of trips of an elevator car of the elevator, a trip-dependent physical parameter value which unambiguously depends on at least one of a trip duration and a trip distance; and (b) clustering the determined trip-dependent physical parameter values to clusters to define each of the floors in the mapping. In a training phase, the method automatically determines the number of floors served and then, in an operation phase, classifies each of the observed trips and finally detects and tracks a current position of the elevator car. An elevator monitoring device implementing such method may be retrofitted into existing elevators for e.g. remotely monitoring the elevator operation and does not necessarily require any data transfer between components of the elevator and the elevator monitoring device.

Abstract: The application relates to a method for creating a framework or truss dataset of an escalator or moving walkway using a computer program. In this method, client-specific configuration data are collected, a type-specific, two-dimensional layout is selected, and this layout is adapted in terms of the conveyor height in accordance with the configuration data. In addition, the guideway of the adapted layout is checked using division sections and the layout is transformed into a subdivided two-dimensional layout. The latter is overlaid with fields of defined structure, wherein the resulting overlaid layout serves as a starting point for arranging profile bar datasets in the three-dimensional space.
