Abstract

Die Erfindung betrifft eine Sicherheitsüberwachungseinrichtung für eine in einem Aufzugsschacht (A) mittels eines Fahrantriebs (D) über eine Aufzugssteuerung (9) verfahrbare Aufzugskabine (1), deren momentane Position mittels einer Positionserfassungseinrichtung erfaßbar ist, die zwei unabhängig voneinander erstellte Positionssignale in einem vorbestimmten Zeitraster liefert, mit einer zweikanaligen Auswertung der Positionssignale durch jeweils einen Mikroprozessor (13a, 13b) zur ortsabhängigen, momentanen Bestimmung der Geschwindigkeit der Aufzugskabine (1 ) und zum Vergleichen mit einem vorgegebenen Bewegungsprofil, wobei bei Überschreiten eines vorbestimmten momentanen Geschwindigkeitssollwertes ein über eine Sicherheitsrelaisstufe (19) abgebbares Auslösesignal erzeugbar ist.

The invention relates to a safety monitoring device for an elevator car (A) which can be moved by means of a travel drive (D) via an elevator control (9) whose instantaneous position can be detected by means of a position detection device, the two independently generated position signals in a predetermined time grid provides, with a two-channel evaluation of the position signals by a respective microprocessor (13a, 13b) for location-dependent, instantaneous determination of the speed of the elevator car (1) and to compare with a predetermined motion profile, wherein when a predetermined instantaneous speed setpoint is exceeded via a safety relay stage (19 ) can be generated releasable trigger signal.
