A door leading edge sensor has: a door leading edge elastic member which is attached to a front end portion of a door in a door closing direction and in which a cavity extending in a direction intersecting with the closing direction is formed therein; and a linear pressure sensitive sensor that is attached to the door leading edge elastic member and is disposed along the extending direction of the cavity. The pressure sensitive sensor has an insulator tube having such an elasticity as to be deformed in accordance with an elastic deformation of the door leading edge elastic member and plural conductive members fixed to an inner surface of the insulator tube. The plural conductive members are in a non-contact state when the insulator tube is not deformed and are in contact with each other when the insulator tube is deformed.

A sensing edge is made in segments that can be used to determine at which point along the edge an obstruction occurred. Data collected can be used to determine a point in a process that the fault occurred by addressing each segment individually or as a whole. A programmable controller can be operatively coupled to the sensing edge, and can include logic to control the door and/or other equipment using data collected from the sensing edge.

A monitoring method to detect a state of a door (2) provided with a locking system (2c). The method comprises the following steps: a measurement step during which a mechanical wave sensor (7) measures a signal corresponding to a mechanical wave propagated in the door (2); a step of comparison between a reference signal stored in the memory (8) and the mechanical wave signal in order to detect a state of the door (2).

The reference signal is measured by the mechanical wave sensor (7) while the locking system (2c) of the door (2) is actuated.
