Definitions

  • the invention relates to the control of a screen winder actuator, and more specifically to the management in time of use phases and maintenance phase of a screen winder actuator.
  • the end of travel of the movable element is detected by an increase in the driving torque and, after detection, the power supply of the
  • the actuator is cut off and a brake blocks the transmission chain between the actuator and the movable element, to prevent any subsequent movement of the movable element.
  • the constraints generated in the transmission kinematic chain are then maintained, to the detriment of the service life of the system.
  • an expansion phase also called “de-stressing” phase
  • the duration of this relaxation phase is typically 70 ms to 100 ms.
  • the duration of the relaxation phase can be prerecorded in the system. In practice, however, it may be useful to adjust this value, in particular because the system undergoes during its lifetime permanent wear and deformations that render the initial setting inoperative or excessive. Because the relaxing effect is not directly visible by the installer, it has been proposed in the document EP 1 659 252 providing, in a system programming mode, a de-wrinkling time adjustment procedure in which the system acknowledges the adjustment instructions in a visible manner, allowing the operator to determine whether his choice of a de-stressing time is located inside or at a terminal of a predetermined variation interval.
  • An evolution of the de-stressing function consists in providing a triggered de-stressing step on detection of a threshold overrun by a parameter of operation of the actuator, in particular a torque threshold, when driving the element in a driving direction, a step during which the actuator drives the element in the other driving direction for a period of time predetermined, which can be for example 100 ms and set at the factory during manufacture of the actuating device. Since the same actuating device can be adapted to various movable elements of closure, concealment, sunscreen or screen, the factory setting may be unsuitable for certain uses.
  • Actuators are also known which have an automatic learning system of the limit switches. Such systems cyclically readjust their limit switches throughout the life of the product, for example every 56 countdown cycles. During the maintenance phases, the system remains usable, but responds to a full winding order of the retractor by making a lift to the high stop position (followed by a detent), while during the phases of use Normally, the system responds to orders for complete retraction of the reel up to the learned high end position.
  • the learning of the high end position occurs at the end of each maintenance phase from the high stop position, for example by rotating the actuator in the closing direction for a predetermined time at from the high stop (for example 70 ms), or by turning the actuator to a predetermined angle (for example a lathe).
  • This operating mode results in a visible difference between the behavior of the system during the use phases and during the maintenance phases, which the unsuspecting user can misinterpret.
  • the invention aims to overcome the disadvantages of the state of the art and to provide means to make imperceptible to the user the passage of a screen winder actuator by maintenance and use phases.
  • the term "screen” is used here and throughout the present application generically to designate any closure element, occultation, sun protection or roll-up screen, preferably a shutter or blind.
  • the first direction of movement will be a direction of winding
  • the second direction of displacement will be a direction of unwinding
  • the first position of end of stroke of use will be a position of end of winding stroke
  • the extreme position in the first direction of movement will be an extreme winding position defined for example by a material stop.
  • the objective of the maintenance phases is to reset at least the first end position relative to the end position in the first direction of movement (in practice, a position defined by a physical stop). ), this adjustment may be required either due to drift over time between the position calculated by the actuator and the actual position of the screen, or because of a possible elongation of the screen or deformation any element in the kinematic chain between the actuator and the screen.
  • the movement from the extreme position to the stop position in the second direction of movement combines an effect of relaxation (de-stressing) of the reel and an effect of approximation of the end position. such that any residual difference is practically perceptible by a user, or at least not perceived as a possible malfunction.
  • the method according to the invention makes it possible to harmonize the position of the final blade on two flaps located one beside the other and for which the maintenance and use phases would be shifted.
  • the first end of stroke position of use is a stored or programmed position.
  • the programming may consist in predetermining an activation time of the actuator or a number of actuator activation fraction fractions in the second direction of movement after reaching the end position in the first direction of movement.
  • control unit of the actuator in response to the detection of the reaching of the end position in the first direction of movement during the maintenance phases, controls the movement of the screen in the second direction of movement for a predetermined time stored to a stop position.
  • the control unit of the actuator in response to the detection of reaching the end position in the first direction of movement during the maintenance phases, controls the movement of the screen in the second direction of movement on a predetermined angle of rotation stored to a stop position.
  • This angle can in particular be determined by counting a corresponding number of turns fractions.
  • the displacement instructions in the first direction of movement, of displacement in the second direction of movement and of complete displacement in the first direction of movement are emitted from a man-machine interface, preferably from a fixed or nomadic remote control.
  • the control unit determines a current position of the actuator and the screen by incrementation and decrementation of a counter and that during the maintenance phases, the control unit recalibrates the counter in response to the detection of the reaching of the extreme position in the first direction of movement.
  • the operation mode in the use phases is particularly simple and requires very little means, and the maintenance phases allow, without interrupting the use, to avoid a too sensitive deviation of operation.
  • the end position in the first direction of movement is a position in which the screen abuts against a fixed stop.
  • the use phases correspond to at least 80%, and preferably at least 90%, or even at least 92% of the total duration of use or the total angular distance traveled by the actuator.
  • the method is implemented only when the distance between the end position in the first direction of movement and the first end position is greater than a predefined value, for example when the linear distance between the extreme position in the first direction of movement and the first end position is greater than 2 cm.
  • this relates to a control method of a screen winder actuator comprising phases of use separated by maintenance phases, the screen being movable between a position high winding and at least one lower end position through a high end position, such as during the use phases, a control unit of the actuator responds to winding or unwinding instructions by controlling the actuator to position the screen between the high end position and the low end position, but without winding the screen to the wound up position beyond the end position high.
  • the actuator control unit responds to a complete winding instruction of the screen, commanding the actuator to drive the screen to the wound up position, detecting reaching the wound up position and, in response to the detection of reaching the wound up position, by scrolling the screen to a stop position.
  • control unit is able, during the cycles of use, to determine a current position of the actuator and the screen by incrementation and decrementation of a counter and to reset the counter during the maintenance phases in response to detecting that the end position is reached in the first direction of travel.
  • the home automation system illustrated on the Figures 1 and 2 is installed in a building having an opening 1, window or door, equipped with a screen 2 belonging to a concealment device 3, in this case a shutter.

  • the shutter 3 may for example comprise, in known manner, an apron comprising horizontal blades articulated to each other, forming the screen 2, and guided by two lateral rails 6. These blades are contiguous when the deck 2 reaches its position low unrolled.
  • the extreme high position wound corresponds to the support of a final end plate 8 L-shaped apron 2 of the shutter 3, or studs fixed perpendicular to the final blade against a fixed stop, for example an edge of a box 9 of the shutter 3.
  • fixed stop means any structural element whose position is fixed relative to the box 9 of the shutter and which interferes with the deck 2 in the extreme high position.
  • the low position unrolled corresponds to the support of the final end blade 8 of the deck 2 of the shutter 3 against a threshold 7 of the opening 1.
  • a high end position can be set away from the position high rolled up.
  • a low end position can be defined, either confused with the extreme low position unrolled, or at a distance from the latter.
  • the first blade of the shutter 3, opposite to the end plate, is connected to the winding tube 4 by means of at least one hinge 10.
  • the winding tube 4 is disposed inside the trunk 9 of the roller shutter 3.
  • the trunk 9 is disposed above the opening 1, or in the upper part of the opening 1.
  • apron 2 of the shutter 3 wraps and unrolls around the winding tube 4 and is housed at least partly inside the trunk 9.
  • the motor drive device 5 is controlled by a control unit.
  • the control unit may be, for example, a local control unit 12, optionally connected in a wired or wireless connection with a central control unit 13.
  • the central control unit 13 controls the local control unit 12, as well as other similar local control units distributed throughout the building.
  • the central control unit 13 may be in communication with a remote weather station outside the building, including, in particular, one or more sensors that can be configured to determine, for example, a temperature, a brightness, or a speed Wind.
  • the motorized drive device 5 is preferably configured to execute the unwinding or winding commands of the screen 2 of the occultation device 3, which can be transmitted, in particular, by the remote control 14.
  • the electromechanical actuator 11 comprises an electric motor 16.
  • the electric motor 16 comprises a rotor and a stator, not shown and positioned coaxially around an axis of rotation X, which is also the axis of rotation of the tube. winding 4 in the mounted configuration of the motor drive device 5.
  • the electromechanical actuator 11 also comprises a reduction gear (not shown), in particular an epicyclic reduction gear in one or more stages.
  • Control means of the electromechanical actuator 11 allowing the displacement of the screen 2 of the occulting device 3, are constituted by at least one electronic control unit 15.
  • the control means of the electromechanical actuator 11 and in particular the electronic control unit 15, comprise hardware and / or software means.
  • the hardware means may comprise at least one microcontroller.
  • the electronic control unit 15 is able to put into operation the electric motor 16 of the electromechanical actuator 11, and, in particular, to allow the electric power supply of the electric motor 16, so as to open or close the screen 2, as previously described.
  • the electronic control unit 15 also comprises a command order receiving module emitted by a command transmitter, such as the remote control 14 intended to control the electromechanical actuator 11 or one of the local control units 12 or central 13.
  • control command receiving module of the electronic control unit 15 is wireless type.
  • the control command receiving module may be configured to receive radio control commands. It can also be envisaged, alternatively or additionally, that the command order receiving module may also allow the reception of control commands transmitted by wire means.
  • the electronic control unit 15 furthermore receives information on the intensity of the supply current of the electric motor 16, and of at least one rotor rotation sensor of the electric motor 16 or of the winding tube 4, which allows to increment and decrement one or more impulse counters of the electronic control unit 15.
  • a first learning phase comprises a predefined number of learning cycles (here 4), during which the flap is driven on command by one of the control units, several times towards its extreme high winding position (corresponding to a mechanical stop) and towards its extreme low position unrolled.
  • the extreme high rolled up and low rolled positions are learned.
  • the control unit 15 determines that an extreme position is reached, for example by detecting the exceeding a torque threshold (or the intensity of the motor supply current) for a given time, and identify which count value this position corresponds to.
  • the count values are defined for example by an angular position of the winding tube and / or a number of fractional turns of the winding tube, read with the rotation sensor. These positions can be defined with respect to an angular position of the output shaft of the actuator or the rotor. Alternatively these positions are defined by a time counter. At least one of the extreme high and low rolled positions can be considered as a reference position.
  • the high end position is determined for example at the end of the learning phase PhA. It may be a preprogrammed position, corresponding for example to a predetermined number of fixed N-turn fractions from the extreme high position, or a predetermined operating time from the extreme high position.
  • the upper limit position is manually set by the installer, who manually shifts (for example using a remote control) the final blade 8 of the distance that suits him and validates this new position as a high end position, which causes the corresponding distance between the extreme high position and the validated upper end position to be recorded, expressed as a number of fractional revolutions or in activation time. The distance N between the stop and the shifted position is recorded during this setting operation.

  • the shutter 3 is driven by the control unit 15 on command of one of the control units 12, 13, 14, towards its extreme high wound position, and continues its race past the high end position until reaching the extreme high position.
  • This pursuit of movement towards the abutment makes it possible to readjust the counting position and the reference position, and thus to correct deviations which can be induced for example by counting errors or by plastic deformation of the blades.
  • the screen 2 of the shutter 3 is again driven in the opposite direction (in a closing movement) over a distance N from the extreme high position wound towards a stop position.
  • This stop position is substantially equivalent to the high end position reached by the flap during an opening movement.
  • the stop position and the high end position are visually identical for a user, although there may be a slight difference in position from the point of view of the electromechanical actuator 11. A subsequent descent movement has taken place since the stop position to the lowered position.
  • the method according to the invention makes it possible to harmonize the position of the final blade on two flaps located one beside the other and for which the maintenance and use phases would be shifted.

  • the final position reached at the end of the upward (or opening) cycle according to the invention makes it possible to align the positions of the final blades of the two flaps (provided that the distance N chosen for the offset from the wound up position is the same for both parts).
  • the coherence function of the use and maintenance modes can be deactivated.
  • the installer can then choose according to the wishes of the user if the cycles of use and maintenance must be differentiated.
