Abstract
The invention refers to a system for monitoring the position of the doors of a moving car in a cable transportation system, the car comprising two doors and the monitoring system comprising an electronic control unit. The monitoring system comprises a detection target on each door, and a fixed detection device, such as a proximity switch with a field of action, which emits a detection signal when a target passes through the field of action, which is connected to the control unit and is positioned so that it can emit a detection signal when the car passes through a control zone. The control unit determines that the two doors of the car are correctly positioned if the distance between the two doors is less than a predetermined opening threshold.

A system for monitoring the position of the doors of a moving car in a cable transportation system, the car comprising two doors and the monitoring system comprising an electronic control unit, characterized in that the monitoring system comprises:
- a detection target on each door and a proximity detector fixed detection device, with a field of action capable of emitting a detection signal when a target passes through the field of action, the detection device being connected to the control unit and, said detection device being placed in such a way as to be able to emit a detection signal when the target of each door of the car passes through a control zone, and in that the control unit determines, based on the detection signal emitted when the target of each door of the car passes through the control zone, that the two doors of the car are correctly positioned if a gap between the two doors is smaller than a predetermined opening threshold.
