Definitions

  • the present invention relates to a device for control of a roller shutter drive motor motorized consisting of stackable blades, comprising a automation reacting to a variation in torque engine.
  • the device described in patent application DE-A-196 10 877 uses a torsion bar acting on two strain gauges, for example sensors piezoelectric.
  • the device described in the request EP-A-0 822 316 uses a spring opposing the rotation of the motor housing, this rotation being detected by optical sensors or a angular displacement.
  • the torque value thresholds are determined by two springs opposing the rotation of the motor housing, rotation that acts directly on two commanding switches motor power. On winding, the motor is stopped after the roller shutter has traveled predetermined path from the moment the couple has reached the threshold determined by the spring corresponding.
  • the object of the invention is to overcome procedures adjustment and learning.
  • the control device is characterized in that its automation includes means of identifying the kind of limit switch rolling shutter operating by analyzing the variation of engine torque and control adaptation means stopping the engine at the kind of limit switch identified.
  • the automation is thus capable of recognize if the roller shutter is to be rolled up or, on the contrary, if the blades are being to stack up. If the shutter rolls up, the control can simply stop the engine when the variation in engine torque exceeds a certain value corresponding to the arrival in high stop of the last roller shutter blade. On the other hand, if the automation has identified that the blades are stacking there may launch a specific analysis procedure for the evolution of the driving torque in order to identify the genre connecting the roller shutter deck to its tube and stop the engine according to particular criteria adapted to each type of fixation.
  • the automation preferably comprises a logical processing unit (ULT) containing a program analysis of the variation of the engine torque according to which we determine if the roller shutter is in phase winding or unwinding or stacking or stacking, we save the detected state, we wait detection of a state different from the recorded state, we record this different state and determine the kind of end of race by analyzing the sequence of two registered states.
  • ULT logical processing unit
  • the ULT after having detected the cancellation of the engine torque corresponding to the end of the stacking of the slides, analysis by means of a subroutine, the evolution of the engine torque from from zero: if the torque remains zero for a predetermined time, which corresponds to a strap attachment, or if the torque evolves relatively slowly from zero, which corresponds to a fixing by foil, the automation immediately stops feeding of the motor. On the other hand, if the couple increases quickly, which means rigid attachment by lock, the automation interrupts the supply of motor when the variation of the motor torque reaches a predetermined value, as happens generally when the roller shutter arrives in stop in high position.
  • the control device shown schematically in FIG. 1 comprises a torque detector 1, consisting for example of a micro-displacement sensor as described in patent EP-A-0 665 416, measuring the torsion of a torsion element supporting the motor M, an analog-digital converter (CAN) 2 converting the signal supplied by the sensor 1 in a digital signal introduced in a ULT 3 equipped with a microprocessor, an interface 4, principle also consisting of a converter analog-digital for entering a parameter of engine operation measured on the engine and its introduction to ULT 3.
  • the control system further includes a manual control 5 of down up.
  • Figure 2 shows the shape of the torque C as a function of time t.
  • the time t0 corresponds to the position fully rolled up. If we start from this position, we first notes that the couple suddenly drops, which corresponds to a relaxation of the rolled up blind with its last blade resting against a stop, by example a blind box, the arrival at the stop having creates a certain tension on the blind, i.e. a torque on the engine. We then observe that, in a zone A, the torque increases according to a wavy curve, this ripple being due to simultaneous variations the winding diameter and the number of blades suspended shutters. Then begins a phase stacking which results in a rapid decrease in torque corresponding to part B of the curve.
  • the couple can evolve in three ways different, depending on whether it is rigidly fixed by a latch, strap or tinsel. If it is fixed by a lock, the engine immediately encounters a strong resistance and the torque curve increases very quickly as represented by line D. If by against the roller shutter is fixed by straps, these straps loosen completely and torque remains void and would remain so until the roller shutter wraps in the other direction on its winding tube, which of course should be avoided. If the shutter roller is fixed by a foil, the elasticity of this makes the torque evolve relatively slowly and irregularly as represented by the part F of the curve.
  • Zones 1 and 0 correspond respectively to parts A and B of the curve.
