ABSTRACT:
A monitoring system for monitoring doors such as a shaft or cabin door, of a lift installation includes a sensor element associated with the doors for monitoring the state or position of the door. An evaluation system is connected to the sensor element and evaluates the sensor signals. The evaluation system can perform continued evaluation in short time intervals in order to provide a continuous record of the state of the monitored doors and temporal changes in the signal characteristics of the sensor signals.
