Method for monitoring the landing doors of an elevator

摘要

The method involves monitoring the closed position of shaft door (7) panels with at least one contactless monitoring sensor (10) emitting electromagnetic waves (10.3). A transmitter (10.1) emits waves extending over several floors, at least during known detection phases, that are detected by a receiver (10.2). The waves are arranged so that a door not fully closed or a lock not fully engaged is detected and signaled to the elevator controller.
