Description

Title of the invention: Method for controlling a motorized swing shutter installation The invention relates to a method for controlling a motorized swing shutter installation. The invention also relates to a motorized swing shutter installation.

Many European countries have a traditional habitat in which the houses are fitted with hinged shutters, that is to say shutters pivoting around a vertical axis. These shutters are generally arranged in pairs, comprising a single leaf and a leaf with joint cover, covering the single leaf in the closed position.

Most shutter installations are manual, but there are many motorization solutions which allow the rotation and synchronized actuation of a single leaf and a covering leaf.

Swing shutter installations have specific usage constraints in the presence of all wind-related situations: weak established wind, strong established wind, gusty wind, turning wind etc. These situations varying themselves on the same site and from one site to another, risk studies generally lead to an oversizing of motorizations, so as to be able to face all situations, in particular to try to avoid engine failures. The result is heavy and bulky products, unattractive, expensive and difficult to install.

Patent EP2453092 describes an installation of a shutter for which the actuator is undersized, so that it cannot move the wings when the wind speed exceeds 30m / s, the installation being provided with manual means of declutching. In this way, in case of strong wind, even if the actuator cannot operate the leaves, it is possible to do it simply manually.

Even in the case of an installation sized to withstand strong winds, it is possible that the installation finds itself in a situation where the movement is blocked and for which the leaves cannot be moved to a position of safety in which they are no longer subjected to the action of the wind.

There is therefore a need for an alternative operating method improving the operation of the operating devices known from the prior art.

The object of the invention is to provide a method of controlling a motorized swing shutter installation overcoming the drawbacks mentioned and improving the operating devices known from the prior art. In particular, the invention provides an installation capable of being protected against external elements, in particular against the effects of wind. The invention further provides a motorized shutter operating device capable of implementing the control method.

Advantageously, the step of executing a safety procedure follows a second step of detecting an opposite action of the wind relative to a second leaf during the movement of the leaves during the procedure. backup.

Advantageously, the at least one wind action detection sensor is a sensor of an internal parameter of a maneuver actuator.

Advantageously, the internal parameter of each actuator is representative of the speed and / or the torque of the electric motor contained in the actuator.

The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawings in which: [0019] [fig. 1] is a perspective view of a home automation installation comprising a motorized swing shutter, [fig.2] schematically represents an embodiment of the motorized shutter.

Figure 1 shows a home automation installation 100 of motorized swing shutter, installed at an opening 2 of a facade 3 of a building, for example an opening equipped with a window not shown. The installation comprises an operating device 1, fixed to a lintel 4, above the opening 2, to a threshold or to a fixing beam located between the lintel and the threshold. The opening 2 is equipped with a flap 5 composed of two leaves or leaves 51 and 52 which can pivot on hinges 6a, 6b so as to cover the opening 2 or to leave it uncovered, as shown in this figure 1 The two leaves are arranged on either side of the opening 2. The operating device 1 comprises a finishing cover 10, covering part of its various components. The operating device 1 thus pilots a flap comprising a main leaf 51 provided with a cover blade 7 or joint cover and a simple secondary leaf 52. The main leaf 51, also called the covering leaf or the master leaf, must be piloted first at the opening and last at the closing to ensure that the covering blade 7 covers the secondary leaf 52, or the slave leaf when the closing. The movements of the two leaves are thus synchronized, the synchronization including an appropriate time difference. Alternatively, this offset is introduced by appropriate mechanics, introducing an offset in position between the leaf movements. The master leaf 51 corresponds to the covering leaf, controlled with the aid of a so-called master actuator. Conversely, the slave leaf corresponds to the covered leaf, piloted using a so-called slave actuator.

Figure 2 schematically shows an embodiment of the motorized home automation system 100, itself comprising the flap 5, the operating device 1, acting on the flaps of the flap 5, and a means 41 for remote control of the operating device 1.

The operating device 1 comprises a first actuator 11 acting on the leaf 51 master via a first connecting means 12 or movement transmission or mechanical coupling, a second actuator 21 acting on the slave leaf 52 via a second connecting means 22 or movement transmission or mechanical coupling. The first and second connecting means 12, 22 comprise for example a pivoting arm 9a, 9b fixedly connected to an output shaft of the first 11 or second 21 actuator and connected with a degree of freedom in translation to a slide fixed on the leaf 51, 52 corresponding. Alternatively, the first and second connecting means 12, 22 comprise an articulated arm 9a, 9b. This, in known manner, is fixed on the one hand to the output shaft of the first 11 or second 21 actuator and on the other hand pivoting on the leaf 51, 52 corresponding. A joint arranged between the ends of the arm allows it to bend according to the need for movement. The first leaf 51 pivots, using hinges 6a, 6b about a first vertical axis 53 and the second leaf 52 pivots around a second vertical axis 54. As in patent application EP 2 453 092, the rotation of the output shaft of the actuator 11, 21 causes that of the leaf 51, 52.

The first actuator 11 comprises a first motor 13 and the second actuator 21 comprises a second motor 23, represented by arrows directed towards the actuators 11, 12. The two actuators 11,12 are connected to at least one control unit 30, respectively by a first supply link 31 and by a second supply link 32. Preferably, the control unit 30 is integrated into the first actuator 11, and disposed in the same housing 20 as the first motor 13.

The first and second electric motors 13, 23 are of the direct current type, with permanent magnets and collector. These electric motors include a rotor with permanent magnets and a stator with coils that are successfully powered depending on the position of the rotor. The rotor position is defined by brushes and collectors. Alternatively, the first and second electric motors 13, 23 are of the direct current type, with permanent magnets, brushless, also called motors with electronic switching. For these motors, the control card 30 is adapted to ensure the electronic switching of the current supply from one or the other of the stator coils, for example by means of relays. The position of the rotor can be defined for example by one or more sensors.

The mechanical output of a motor is connected to a reduction gear, the output shaft of which is an output shaft of the actuator connected to the connecting means 12, 22. A declutching means, not shown, can be inserted between the motor and the gearbox output shaft, which allows a user to manually operate one or the other of the leaves in the event of a blockage, for example when the leaves are in a locked position or in the event of a cut power.

Alternatively or additionally, the operating device 1 comprises a braking means, such as for example a mechanical brake or a magnetic brake. This brake is preferably arranged at the engine outlet, before the reduction gear if the latter is of the reversible type and before the declutching device. It can also be integrated into the engine. It acts as a braking means at low speed of rotation of the motor shaft, when a movement of the flap is stopped in a given position. It acts in particular as a static blocking means to temporarily maintain the shutter, in particular in an intermediate position, for example against possible jolts caused by gusts of wind or by manual actions, such as burglary attempts , on the leaves or the connecting means 12, 22 of the operating device 1 to the leaves. The brake thus acts as a shock absorber in the presence of a very strong wind.

The control unit 30 is supplied by a supply means 37 comprising for example a photovoltaic panel and an accumulation means, in particular a supercapacitor or a battery. Alternatively, the power supply means 37 comprises a power supply, for example a switching power supply connected to the household electrical network.

The control unit 30 is also connected to a command receiver 38, of the radio frequency type and preferably bidirectional. The command receiver 38 communicates with a radio frequency network 40 of the home automation type. A remote control means 41, such as a remote control, also communicates with the radio frequency network 40 and the command receiver 38 is able to receive orders from the remote control means 41, when a user acts on a control interface 42 of the remote control means 41. Conversely, the remote control means 41 can send a sensitive signal to the user using a sensitive means 43, if it receives a particular message in from the command receiver 38. To this end, the control unit 30 includes a signaling program 30a. The signaling program, the sensitive means, the transmitter of orders and the receiver of orders, then constitute a signaling means of the operating device 1.

The first actuator 11 is designated by "master actuator", while the second actuator 12 is designated by "slave actuator". The operation of each actuator 11,12 results in the evolution of at least one internal parameter of the actuator. A first internal parameter of the actuator is representative of its speed, a second internal parameter of the actuator is representative of its torque, reflecting the force exerted on the leaf 51, 52 by the actuator 11,21 and / or exerted by the leaf 51, 52 on the actuator 11, 21. This latter force includes in particular an external force, such as wind, exerted on the leaf. Preferably, the internal parameters are measured at the level of the electric motor 13, 23 of each actuator 11, 12. To transmit the value of the first internal parameter of each actuator, a first signal 33 is transmitted by the first actuator 11 to the unit of command 30 and a second signal 34 is transmitted by the second actuator 21 to the control unit 30. Similarly, to transmit the value of the second internal parameter of each actuator, a third signal 35 is transmitted by the first actuator 11 to the the control unit 30 and a fourth signal 36 is transmitted by the second actuator 21 to the control unit 30.

The first, second, third or fourth signal can come from sensors internal to the actuators 11, 21, for example torque sensors and / or speed sensors.

Alternatively, a signal, or the two signals from each actuator, is taken, or are taken, directly from the actuator supply link, as shown in dotted lines under the references 34 ’and 36’. These include parameters associated with powering the actuator. For example, a measurement of the current supplied to the actuator and / or a measurement of the voltage across the actuator gives information on the torque and / or speed of the actuator. In this case, this information is directly processed within the control unit 30. One or more of the sensors internal to the actuators forms at least in part, a sensor for detecting a wind action. Such signals are representative in particular of the effects of the wind on a wing.

The control unit 30 comprises a program for detecting the effects of wind 30b by analyzing the signals 33, 34, 35, 36. The means emitting the signals and the program for detecting the effects of wind constitute a means of detection of the wind from the operating device 1. The program for detecting the effects of wind 30b by analyzing the signals 33, 34, 35, 36 corresponds to a program for detecting an obstacle on a leaf 51, 52 of the flap 5.

The wind can act on the flaps of the shutter, as shown by an arrow 60. This wind may include a component 60i parallel to the facade 3 and a component 60j perpendicular to the facade 3, the facade 3 being itself parallel to the plane passing through the axes 53, 54.

Depending on the position of the leaves, the wind can also be broken down with a component parallel to the surface of the leaf and a component perpendicular to the surface of the leaf. The component perpendicular to the leaf surface and opposing the movement of the leaf in the opposite direction to this perpendicular component creates an opposite action of the wind on the leaf.

The operating device 1 comprises hardware and / or software means, making it possible to govern its operation in accordance with the process which is the subject of the invention, in particular to govern the stages of this process and their sequences. The hardware means include the control unit 30, in particular a microprocessor not shown in the control unit. The software means may be contained in the control unit 30, in particular in the microprocessor and / or a memory of the control unit 30. The software means may in particular include a computer program code suitable for carrying out the steps of method according to the invention, when the program runs on a microprocessor.

FIG. 3 represents a first mode of execution of a control method or an operating method of an operating device according to the invention, implemented by the operating device 1.

In a first step RI, the control unit 30 receives, via the command receiver 38, an order for movement of the shutter. This movement order is recorded in a memory of the control unit.

In a second step R2, the operating device 1 seeks to execute the received movement order. The control unit 30 supplies at least one first actuator. Preferably, the master actuator 11 is supplied before the slave actuator 21 during an opening movement of the shutter 5, while the slave actuator 21 is supplied before the master actuator 11 during a closing movement of the flap 5. During the execution of this movement order, the control unit 30 scans the signals received and / or the parameters associated with the actuator or actuators 11, 21 in movement. In particular, the control unit 30 scans the information provided by the wind action detection sensor.

In a third step R3, taking place during the execution of the movement order, in the presence of wind, a positive action of the wind accompanying the movement of the first leaf is monitored. In particular, a positive action of the wind results in an effort in the direction of movement of the leaf. This positive action is reflected in particular by a resisting force at the level of the actuator, for example a braking force or even an operation of the engine as a generator or by an overspeed. Indeed, the actuator seeks in particular to regulate the speed during movements and the parameters influencing the speed are modified by the positive action of the wind. Alternatively, the actuator seeks to regulate the torque supplied to achieve the movement of the leaf and the parameters influencing the torque are modified by the positive action of the wind. Detection is carried out as indicated above by analyzing at least one internal parameter of the actuator or by analyzing the signals from each actuator. When this positive wind action exceeds a predetermined threshold, the control unit 30 is instructed to initiate a safety procedure. The security procedure includes two simultaneous or successive steps.

A fourth step R4 consists in desynchronizing the movements of the two leaves, that is to say that the movements of the master leaf and of the slave leaf are carried out independently of one another. A fifth step R5 consists in positioning the two leaves so that one leaf is open and the other leaf is closed. To do this, the actuator continues the movement of the first leaf, on which the positive action of the wind has been detected, and reverses the direction of movement or maintains the second leaf in position until it stops when of a step R6. Indeed, depending on whether the movement of the second leaf has already been initiated or not, it is necessary to return it to its initial position or not. The return of the second leaf to its initial position being in the same direction of rotation as the movement of the first leaf, it is subjected to the positive action of the wind. In the absence of a positive wind action, the movement of the two leaves 51, 52 continues during a step R7.

FIG. 5 represents a second embodiment of a control method or an operating method of an operating device according to the invention, implemented by the operating device.

In a first step SI, the control unit 30 receives, via the command receiver 38, an order for movement of the shutter. This movement order is recorded in a memory of the control unit.

In a second step S2, the operating device 1 seeks to execute the received movement order. The control unit 30 supplies at least one first actuator. Preferably, the master actuator 11 is supplied before the slave actuator 21 during an opening movement of the shutter 5, while the slave actuator 21 is supplied before the master actuator 11 during a closing movement of the flap 5. During the execution of this movement order, the control unit 30 scans the signals received and / or the parameters associated with the actuator or actuators in motion.

In a third step S3, taking place during the execution of the movement order, in the presence of wind, an opposite action of the wind opposing the expected movement of the leaf is detected. In particular, this opposite action of the wind results in an effort opposing the movement in the expected direction of the leaf. This opposite action results in particular in an overtorque which the actuator must provide or in an underspeed. Indeed, the actuator seeks in particular to regulate the speed during movements and the parameters influencing the speed are modified by the opposite action of the wind. Alternatively, the actuator seeks to regulate the torque supplied to achieve the movement of the leaf and the parameters influencing the torque are modified by the opposite action of the wind. Detection is carried out as indicated above by analyzing at least one internal parameter of the actuator or by analyzing the signals from each actuator. When this wind action exceeds a predetermined threshold, the control unit 30 is instructed to trigger a backup procedure. If no contrary wind action is detected at this stage of the process, the movement continues in accordance with the order received.

In a fourth step S4, the control unit performs a backup procedure. The purpose of this is to put the shutter in a safety position vis-à-vis the effects of the wind. According to the state of the art, a first safety position is the fully open position of the shutter and a second safety position is the fully closed position of the shutter. This safeguarding procedure notably involves continuing or reversing the movement of the leaves, in order to reach one or the other of the security positions. The choice of going to a security position rather than the other depends on the analysis of at least one internal parameter of the actuator, as explained for example in relation to FIG. 2.

In a fifth step S5, during the execution of this saving procedure, the control unit checks whether an opposite action of the wind on the second leaf is detected. In particular, when moving towards the safety position, the second leaf may find itself during its movement in a position such that the wind generates an action contrary to the movement of this second leaf.

In the event of detection of an opposite action of the wind and when this opposite action reaches a second predetermined threshold, the control unit 30 causes a desynchronization of the movement of the leaves 51, 52 during a step S6, then an inversion of movement of the second leaf during a step S7. The second leaf continues its movement until it reaches its limit position.

The shutter is found at the end of this saving procedure during a step S8, with an open leaf and a closed leaf, corresponding to a third safety position. This safety position is maintained in particular as long as a user or a sensor does not give a new movement order.

During the backup procedure, it is possible that there is no detection of an opposite action of the wind on the second leaf. This is the case for example if the opposite action on the first leaf was due to a punctual gust of wind. In this case, the saving procedure conventionally continues during a step S9, to reach the first or second safety position during a step S10.

Figures 4, 6, 7 and 8 show different examples of execution of the control method according to the invention, implemented by the operating device. In these examples, the shutter installation is shown schematically in plan view and the main wind direction is represented by a side arrow. The directions of movement of the leaves 51, 52 are represented by rounded arrows indicating the direction of rotation of the leaf around its axis 53, 54.

Figure 5 shows a first example of an opening movement of the shutter, the wind being oriented in such a way that it opposes the opening of the slave leaf 52 and the closing of the master leaf 51 .

During the opening movement, from a first extreme closed position, the master leaf 51 is opened first. The action of the wind is a positive action, the effect of which is to accompany the movement of the leaf. This positive action can be detected by the wind action detection sensor. When this positive action exceeds a predetermined threshold, a safety procedure is triggered. This first of all causes a desynchronization of the movements of the first master leaf 51 and of the second slave leaf 52. In other words, if the movement of the slave leaf 52 did not start upon detection, its movement n 'is not initiated; if the opening movement of the slave leaf has started, this movement is stopped as well as a reversal of direction, so that the slave leaf returns to its initial position. At the end of this safety procedure, the first master leaf 51 is stopped in the second extreme position and the second slave leaf 52 in the first extreme position. A similar operation can be carried out during a closing movement, if a positive action of the wind is detected during the movement of the first leaf.

6 shows a second example of an opening movement of the shutter, the wind being oriented in such a way that it opposes the opening of the slave leaf 52 and the closing of the master leaf 51 .

During the opening movement, the master leaf 51 is opened first. The action of the wind is a positive action, the effect of which is to accompany the movement of the leaf. Although this positive action can also be detected, it does not trigger the backup procedure. On the other hand, at the opening of the second leaf 52, the slave leaf is subjected to an opposite action of the wind, opposing its opening movement. This opposite action of the wind is represented by a hatched arrow.

Upon detection of this opposite action of the wind or first detection, on the second leaf, a backup procedure is initiated, in which the control unit 30 seeks to close the flaps of the shutter, that is to say tell to return to the closed initial state of the shutter.

During this saving procedure, the slave leaf 52 can easily be closed, since it benefits from the positive action of the wind during its closing movement. On the other hand, the master leaf 51 being partially open, its closing opposes the action of the wind, represented by a hatched arrow. Again, an opposite wind action is detected.

This second detection, on the first leaf, in addition to the first detection, triggers the establishment of the flap in a safety position, in which one leaf is open while the other leaf is closed. In the example, the movement of the leaves 51, 52 is out of synchronization and then the master leaf 51 is open, that is to say its movement is again reversed to move it to an open position, while the slave leaf 52 is closed, i.e. its closing movement continues to move it to a closed position.

FIG. 7 represents an embodiment of the method according to the invention, during a movement for closing the shutter, the wind being oriented in the same manner as in FIG. 4, that is to say say in such a way that it opposes the closing of the master leaf 51 and the opening of the slave leaf.

During the closing movement, the slave leaf 52 is closed first. The action of the wind is a positive action, the effect of which is to accompany the movement of the leaf. When the second leaf 51 closes, the master leaf 51 is subjected to an opposite action of the wind, opposing its closing movement. This opposite action of the wind is represented by a hatched arrow.

Upon detection of this opposite action of the wind or first detection, on the second leaf 51, a backup procedure is initiated, in which the control unit 30 seeks to reopen the flaps of the shutter, that is to say - tell to return to the initial open state of the shutter.

During this backup procedure, the master leaf 51 can easily be reopened, since it benefits during its opening movement from the positive action of the wind. On the other hand, the closing of the slave leaf 52 opposes the action of the wind, represented by a hatched arrow. Again, the opposite action of the wind is detected.

This second detection, on the second leaf, added to the first detection, triggers the establishment of the flap in a safety position, in which one leaf is open while the other leaf is closed. In the example, the master leaf 51 is open, while the slave leaf 52 is closed.

This safety position is maintained in particular as long as a user or a sensor does not give a new order of movement or as long as the leaves are not manipulated manually, following a disengagement of the kinematic chain.

8 shows an embodiment of the method according to the invention, during a movement of closing the shutter, the wind being oriented in the opposite direction to that shown in Figure 5, that is to say say in such a way that it opposes the closing of the slave leaf 52.

During the closing movement, the slave leaf 52 is closed first. When this slave leaf 52 is closed, it is subjected to an opposite action of the wind, opposing its closing movement. This opposite action of the wind is represented by a hatched arrow.

Upon detection of this contrary action of the wind or first detection, on the first leaf, a backup procedure is initiated, in which the control unit 30 seeks to reopen the flaps of the shutter, that is to say tell to return to the initial open state of the shutter. The first detection can take place when the master leaf 51 has not yet been moved. In this case, the backup procedure consists in reopening the slave leaf 52. In fact, the slave leaf 52 can easily be reopened, since it benefits from the positive action of the wind during its opening movement. The shutter then remains in this open safety position.

Alternatively, the first detection can take place while the master leaf 51 has already been substantially displaced. During this saving procedure, the slave leaf 52 can easily be reopened, since it benefits during its opening movement from the positive action of the wind. On the other hand, the closing of the master leaf 51 opposes the action of the wind, represented by a solid arrow. Again, the opposite action of the wind is detected.

This second detection, on the second leaf, added to the first detection, triggers the establishment of the shutter in a safety position, in which one leaf is open while the other leaf is closed. In the example, the slave leaf 52 is open, while the master leaf is closed 51.

This safety position is maintained in particular as long as a user or a sensor does not give a new movement order.

The detection of a contrary action of the wind corresponds in particular to a growth in the resistant force detected at the level of the actuator corresponding to the leaf concerned. This is for example an increase in the torque supplied by the electric motor. In this case, the control unit 30 initiates the saving procedure, which will result in the reversal of the movement of the leaf concerned.

When placing in the safety position, the movement of each leaf continues until it reaches a limit stop (fully closed or fully opened).

In summary, the invention proposes an original solution, which differs from the teaching of the prior art, in which a safety position implies either a completely open or completely closed position, or an intermediate position in which the two flaps are stopped in their course at the point of detection and finally strongly subjected to the action of the wind. The safety position according to the invention, in which one of the leaves is open while the second is closed, is also an indicator that the installation 100 has been subjected to a strong wind during a movement.
