Definitions
- the subject of the present invention is a method of detecting an unauthorized action on a motorized occultation element, such as a rolling shutter or a tilting door or one that moves in translation, kinematically linked to an electric drive motor set in action by a control device.
- a motorized occultation element such as a rolling shutter or a tilting door or one that moves in translation, kinematically linked to an electric drive motor set in action by a control device.
- the invention also relates to a device for implementing the method.
- Patent FR 2 657 646 discloses a security device for a roller shutter in which an intrusion attempt is detected by the observation of an uncontrolled movement of the roller shutter.
- this solution requires means for detecting the lifting of the lower bar or load bar of the roller shutter and therefore either detection means arranged at the bottom of the bay obscured by the roller shutter or a mechanical connection. between this load bar and the top of the bay.
- Patent FR 2 381 364 describes a safety blind in which a manipulation exerted on the fabric is detected by the combined observation of a variation in force applied to the support of the fabric and of a vibration of the fabric.
- an intrusion attempt is detected by observing an uncontrolled rotation of the disc of an optical encoder linked to the motor.
- the object of the present invention is the speed of detecting an intrusion attempt as soon as a force is exerted on the occulting element, that is to say even before the occulting element is moved.
- the method according to the invention is characterized in that the detection of the appearance of the variation of a torque on the shaft of the drive motor of the concealment element and that an alarm is triggered when the variation torque is detected in the absence of motor power. Detection takes place even before the blackout element is moved significantly.
- This method can be implemented, for example, by a device comprising a torque detector kinematically linked to the motor shaft, a processing logic to which are applied the signal delivered by the torque detector and a signal indicating whether the motor is powered.
- the torque detection can be done, for example, by means of a piezoelectric strain gauge or by means of a micro displacement sensor as described in patent EP 0 665 416.
- FIG. 1 represents the block diagram of a device for controlling a roller shutter.
- Figure " 2 shows the part of the shutter control program relating to the invention.
- the control device shown diagrammatically in FIG. 1 comprises a torque detector 1, consisting for example of a micro displacement sensor as described in patent EP 0 665 416, measuring the torsion of a torsion element supporting the motor M, an analog-digital converter 2 converting the signal supplied by the sensor 1 into a digital signal introduced into a ULT (logic processing unit) 3 equipped with a microprocessor, an interface 4 between the ULT 3, on the one hand, and the motor and an alarm 5, on the other hand, and a manual control 6 up / down.
- the interface 4 also consists of an analog-digital converter for the introduction of an engine operating parameter measured on the engine and its introduction into the ULT 3.
- ULT 3 contains a main program consisting of the main program represented in FIG. 3 of patent FR 2 780 089 supplemented by the algorithm represented in FIG. 2 of this document.
- the program first operates an intrusion test which consists in testing the simultaneous presence of a variation in torque on the torque detector 1 and the absence of a command on the motor, this is ie the lack of a supply of it. If this test is positive, an alarm is activated. If the test is negative, the main program, of which only the first test and represented in FIG. 2, is continued as described in patent FR 2 780 089, this description having to be considered as being integrated into the present description.
