    [0001] TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for controlling the operation of a motorized drive device of an installation. home automation, closing or sun protection. The present invention also relates to a motorized drive device of a home automation system for closing or sun protection adapted to implement this control method. In general, the present invention relates to the field of occultation devices comprising a motorized drive device moving a screen between at least a first position and a second position. A motorized driving device comprises an electromechanical actuator of a movable closing, occulting or sun protection element, such as a shutter, a door, a grating, a blind, or any other equivalent equipment, called by the following screen. Already known JP 2005 042 485 A which describes a motorized drive device of a home automation system for closing or sun protection. The home automation closure or sun protection system includes a concealment device. The concealment device comprises a screen, in particular a rolling shutter, and a winding tube. The motorized driving device comprises an electromechanical actuator for winding and unwinding the screen on the winding tube, between a wound position and an unwound position. The electromechanical actuator comprises a DC electric motor. The DC electric motor comprises an output shaft connected to the winding tube of the concealment device. The DC electric motor also includes an electronic control unit. The electronic control unit comprises a device for measuring a physical parameter, in particular an intensity value of the electrical current flowing through the direct current electric motor, a memory storing a plurality of intensity threshold values and a obstacle detection device during winding of the screen or during the course of the screen. The movement of movement of the screen has several portions during the winding of the screen or during the course of the screen. And each portion of the screen displacement stroke is associated with a threshold value of intensity, so as to adapt the obstacle detection sensitivity to each portion of the screen displacement travel. The electronic control unit measures different intensity values passing through the DC electric motor through the measuring device during the displacement of the screen by the motorized drive device. Following the sampling of the measured intensity values, they are converted by an analog / digital converter, then stored in a memory of the electronic control unit, so as to constitute a profile. The intensity values measured are representative of the torque supplied by the DC electric motor of the electromechanical actuator. The electronic control unit comprises means for updating the intensity threshold values obtained by adding a margin to a reference intensity value, the reference intensity value corresponding to a value of intensity measured recently by the measuring device, so as to take into account the seasonal changes and the aging of the home automation system. The reference intensity value corresponds to the measured intensity value having the highest value among the last measured intensity values, or to an intensity value greater than the highest value among the last values. measured intensity values, or at an intermediate intensity value among the last measured intensity values, or at an intensity value corresponding to the average of the last measured intensity values. The margin added to the reference intensity value making it possible to define an intensity threshold value can be different according to the direction of movement of the screen of the occulting device, in particular, during the winding of the screen or when scrolling the screen. The electronic control unit compares the measured intensity values against one of the updated intensity threshold values and determines the presence or absence of an obstacle. However, this motorized drive device has the disadvantage of detecting the stops of high and low end stops during the displacement of the screen of the concealment device by means of additional switches relative to the obstacle detection device implemented in a software manner for detecting an obstacle between the high and low limit stops by the current measuring device passing through the DC electric motor. Consequently, such a motorized drive device comprising, on the one hand, a device for detecting limit stops and, on the other hand, an obstacle detection device generates costly production costs.
    [0002] Furthermore, this motorized driving device comprising an obstacle detection device, where the intensity threshold values are determined by the addition of a margin as a function of the intensity values measured previously, generates difficulties in guaranteeing the updating of the intensity threshold values as a function of the frequency of use of the motorized drive device, of the variations in operation related to the climatic conditions of the environment of the home automation system. Furthermore, this motorized training device requires a learning phase, when commissioning the home automation system, to determine a profile of change in the intensity passing through the electric motor during the course of the screen and when winding the screen. Therefore, the obstacle detection device may cause inadvertent stops of the motor drive device in case the intensity threshold values are too low, or omit to detect obstacles in the case where the threshold values of intensity are too high. The object of the present invention is to solve the aforementioned drawbacks and to propose a control method in operation of a motorized drive device of a home automation system for closing or sun protection, as well as a motorized drive device. associated, to determine the travel limit of movement of the screen, as well as the presence or absence of obstacles, using a same detection device implemented in a software, while minimizing the costs of obtaining the motorized driving device.
    [0003] To this end, the present invention aims, in a first aspect, a control method in operation of a motorized drive device of a home automation system for closing or sun protection, the home automation system for closing or protection solar system comprising a concealment device, the concealment device comprising at least: - a screen, and - a winding tube, the motorized drive device comprising at least: an electromechanical actuator for winding and unrolling The screen on the winding tube, between a wound position and an unwound position, the electromechanical actuator comprising at least: an electric motor, the electric motor comprising an output shaft connected to the winding tube of the winding device; concealment, and an electronic control unit, the electronic control unit comprising at least: a device for measuring a value of intensity an electric current passing through the electric motor, - a memory storing a plurality of intensity threshold values, and 5 - an obstacle detection device and limit switches during winding of the screen and during the screen flow, said method comprises at least: - a step of measuring a first intensity value of the electric current flowing through the electric motor by the measuring device.

Thus, the control method makes it possible to determine whether or not the travel stops of the screen travel, as well as the presence or the absence of an obstacle, by the monitoring of intensity deviations with respect to a first intensity value passing through the electric motor. In this way, the control method makes it possible to determine the presence or absence of an obstacle or a limit switch dynamically, by comparing intensity differences determined from a first intensity value. passing through the electric motor with respect to a selected intensity threshold value according to the period of time elapsed between the measurement time of the first intensity value and the instant of determination of an intensity difference. Consequently, the control method makes it possible to guarantee the protection of the motorized drive device as well as the home automation installation, while limiting the untimely stops of movement of the screen of the concealment device.
    [0005] The implementation of such a control method in which the determination of the presence or absence of an obstacle or a limit switch in a software way by the detection device makes it possible to minimize the costs of obtaining the motorized driving device. Furthermore, the operating control method of the motorized drive device 5 makes it possible to dispense with a learning phase when the home automation system is put into service for the purpose of determining an evolution profile of the intensity of the electric current flowing through the electric motor during the unwinding of the screen and during winding of the screen. According to a preferred characteristic of the invention, this method comprises one or more additional steps for measuring another intensity value passing through the electric motor by the measuring device, following the implementation of the measurement step. the first intensity value passing through the electric motor; a step of determining an evolution of the intensity value passing through the electric motor through the steps of measuring an intensity value passing through the electric motor. The method implements the step of determining an intensity difference with respect to the first measured intensity value when the step of determining an evolution of the intensity value passing through the electric motor determines a increasing the intensity value passing through the electric motor. Practically, in the case where a decrease in the intensity value passing through the electric motor is determined, during the step of determining an evolution of the intensity value passing through the electric motor, the control method implements again the step of measuring the first intensity value passing through the electric motor. According to another preferred feature of the invention, following the step of determining an intensity difference with respect to the first measured intensity value, the method comprises a step of determining an evolution of the intensity difference with respect to the first measured intensity value. In practice, the step of determining an intensity difference with respect to the first measured intensity value is carried out periodically, as long as the result of the step of determining an evolution of the deviation of intensity corresponds to an increase in the intensity value passing through the electric motor. Advantageously, the step of determining an intensity difference with respect to the first measured intensity value is carried out periodically, as long as the result of the step of determining the presence or absence of an obstacle. or end of race is different from an obstacle or a limit switch detected.
    [0006] Preferably, the step of determining an intensity difference with respect to the first measured intensity value is carried out periodically for a predetermined period of time starting from the moment of measurement of the first value. intensity.
    [0007] In practice, the step of measuring the first intensity value passing through the electric motor is carried out following the lapse of a predetermined period of time starting from the starting control moment of the electric motor. According to another preferred feature of the invention, the method also comprises a step of determining the direction of rotation of the output shaft of the electric motor, a step of determining the position of the screen of the occulting device and a step of determining several portions of the movement of movement of the screen during the winding of the screen and during the course of the screen. At least the steps of determining an intensity difference, selecting one of the intensity threshold values, comparing the intensity difference determined with respect to the selected intensity threshold value and determining the presence or absence of an obstacle or a limit switch are implemented during at least a portion of the movement of movement of the screen, during winding of the screen or during the progress of the screen.

These blades are contiguous when the apron 2 of the shutter 3 roll reaches its low position unrolled. In the case of a rolling shutter, the wound up position corresponds to the pressing of a final L-shaped end plate 8 of the deck 2 of the shutter 3 against an edge of a box 9 of the shutter 3, and 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. The first blade of the shutter 3, opposite to the end blade, is connected to the winding tube 4 by means of at least one joint 10. The winding tube 4 is disposed inside the trunk 9 of the shutter 3. The 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, where the local control unit 12 may be wired or wirelessly connected to 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.
    [0014] 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.
    [0015] A remote control 14, which may be a type of local control unit, and provided with a control keyboard, which comprises selection and display means, also allows a user to intervene on the control unit. electromechanical actuator 11 and / or the central control unit 13. The motorized drive device 5 is preferably configured to execute the unwinding or winding commands of the screen 2 of the concealment device 3, The electromechanical actuator 11 comprises an electric motor 16. The electric motor 16 comprises a rotor and a stator positioned coaxially about an axis of rotation X.
    [0016] 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. This electronic control unit 15 is able to implement operation of the electric motor 16 of the electromechanical actuator 11, and in particular to allow the electrical power supply of the electric motor 16. Thus, the electronic control unit 15 controls, in particular the electric motor 16, so as to open or close screen 2, as previously described. The electronic control unit 15 also comprises an order receiving module, in particular radio orders transmitted by a command transmitter, such as the remote control 14 intended to control the electromechanical actuator 11. The receiving module 25 orders may also allow the reception of orders transmitted by wire means. Here, and as illustrated in FIG. 3, the electronic control unit 15 is disposed inside a casing 17 of the electromechanical actuator 11. The control means of the electromechanical actuator 11 comprise 30 hardware and / or software. By way of non-limiting example, the hardware means may comprise at least one microcontroller. The electromechanical actuator 11 belonging to the home automation system of FIGS. 1 and 2 will now be described in greater detail and with reference to FIGS. 3 and 4. The electromechanical actuator 11 is supplied with electrical energy by a control network. mains power supply, or by means of a battery, which can be recharged, for example, by a photovoltaic panel. The electromechanical actuator 11 makes it possible to move the screen 2 of the concealment device 3. Here, the electromechanical actuator 11 comprises a power supply cable 18 allowing its supply of electrical energy from the electrical supply network 5 of the sector . In another embodiment not shown, the electromechanical actuator 11 is intended to be placed in a U-shaped rail. The casing 17 of the electromechanical actuator 11 is preferably of cylindrical shape. In one embodiment, the housing 17 may be made of a metal material. The material of the housing of the electromechanical actuator is not limiting and may be different, and in particular plastic. Here, the electric motor 16 is brushless type with electronic switching, or called "BLDC" (acronym for the BrushLess term Current BrushLess), or called synchronous permanent magnet.
    [0017] The rotor of the electric motor 16 comprises a rotor body provided with magnetic elements surrounded by the stator. Here, the magnetic elements are permanent magnets. The stator of the electric motor 16 is formed by a stator core comprising polar elements distributed on the periphery of the stator. Polar elements are also called teeth. The stator of the electric motor 16 comprises coils 23, in this case three, electrically connected to each other, as illustrated in FIG. 4. Preferably, the coils 23 are positioned around the polar elements of the stator. More precisely, each polar element is surrounded by a winding 23 which is its own. The coils 23 are interconnected so that when they are traversed by a current, they produce a rotating electromagnetic field which rotates the rotor. The electromechanical actuator 11 also comprises a gear reduction device 19 and an output shaft 20. Advantageously, the electric motor 16 and the gear reduction device 19 are disposed inside the casing 17 of the electromechanical actuator 11. The output shaft 20 of the electromechanical actuator 11 is disposed inside the winding tube 4, and at least partly outside the casing 17 of the electromechanical actuator 11.
    [0018] The output shaft 20 of the electromechanical actuator 11 is coupled by a connecting means 30 to the winding tube 4, in particular a wheel-shaped connecting means. The electromechanical actuator 11 also comprises a shutter element 21 at one end of the casing 17.
    [0019] Here, the casing 17 of the electromechanical actuator 11 is fixed to a support 31, in particular a cheek, of the trunk 9 of the concealment device 3 by means of the closing element 21 forming a torque support, particularly a closing head and torque recovery. In such a case where the closure member 21 forms a torque support, the closure element 21 is also called a fixed point of the electromechanical actuator 11. The electronic control unit 15 of the actuator electromechanical circuit 11 comprises a circuit (not shown) for rectifying the AC voltage of the power supply network and a power supply module 22. The power supply module 22 is thus electrically connected to a DC voltage source + Vbus. The value of the DC + Vbus voltage is defined with respect to a reference voltage Gnd. The power supply module 22 sequentially supplies electrical energy to the coils 23 so as to produce the rotating electromagnetic field causing the rotation of the rotor of the electric motor 16.
    [0020] The power supply module 22 comprises switches 24 making it possible to provide the sequential power supply for the coils 23. Here, the switches 24 of the power supply module 22 are "MOSFET" type transistors (acronym for the English term). Saxon Metal Oxide Semiconductor Field Effect Transistor), and six in number. The type of switches of the power supply module and their number are in no way limiting. In particular, the switches 24 of the power supply module 22 may be transistors of the "IGBT" type (acronym for the English term lnsulated Gate Bipolar Transistor). The electronic control unit 15 of the electromechanical actuator 11 comprises a measuring device 28 of an intensity value I of an electric current flowing through the electric motor 16. For the purposes of the present invention, the intensity the electric motor 16 is the intensity of an electric current flowing through the electric motor 16 in operation. The intensity passing through the electric motor 16 is obtained by means of a positive rectified signal taking into account the current of each of the coils 23 of the electric motor 16.
    [0021] The acquisition of the intensity value I passing through the electric motor 16 by means of the measurement device 28 makes it possible to obtain a signal representative of the torque generated by the electric motor 16 of the electromechanical actuator 11. Here , the measuring device 28 of the intensity value I is implemented by means of a so-called "shunt" resistor electrically connected to the electrical power supply module 22 and to the reference voltage Gnd. The measuring device 28 is an integral part of a signal generator 25. This signal generator 25 also comprises an analog filter 26, in particular a low-pass RC circuit, the RC circuit consisting of a resistor and a signal generator. 'a capacity. The signal generator 25 makes it possible to deliver a signal representative of the electrical supply supplied to the electric motor 16, in particular of the intensity I passing through the electric motor 16, to an input of a microcontroller 27. The input of the microcontroller 27 comprises an analog / digital converter 29. The signal of the intensity value I acquired by the measuring device 28 is also digitally processed by at least one digital filter, which can be for example a low-pass filter, implemented by the microcontroller 27. The electronic control unit 15 of the electromechanical actuator 11 comprises a memory storing a plurality of threshold values of intensity S. Here, the memory storing a plurality of intensity threshold values S is achieved by a memory of the microcontroller 27, in particular a memory type "EEPROM" (acronym for the term 20 Anglo-Saxon Electrically Erasable Programmable Read Only Memory ). The electronic control unit 15 of the electromechanical actuator 11 comprises a device for detecting obstacles and limit switches during the winding of the screen 2 and during the unwinding of this screen. The device for detecting obstacles and end-stops during winding and during the unwinding of the screen 2 is implemented by means of the microcontroller 27, and in particular by means of an algorithm implemented by this microcontroller. A method of controlling the operation of the motorized drive device 5 of the home automation system according to the invention shown in FIGS. 1 to 4 will now be described with reference to FIGS. 5 to 7.
    [0022] In FIG. 6, the graph illustrates, by a curve in full line, the evolution of the value of intensity I crossing the electric motor 16, as a function of time t. The time t is represented on the abscissa axis, the intensity value I is represented on the ordinate axis. In FIG. 7, the graph illustrates, by a thick solid line curve, the evolution of the threshold values of intensity S as a function of time t and, by another curve in full line, the evolution of the intensity difference A1 with respect to a first intensity value 11 measured. The time t is represented on the abscissa axis, the intensity threshold values S and the intensity difference Al are represented on the ordinate axis.
    [0023] The control method comprises a measuring step E21 of a first intensity value 11 of the electric current flowing through the electric motor 16 by the measuring device 28, as illustrated in FIG. 6. Preferably, the step of Measurement E21 of the first intensity value 11 is carried out following the lapse of a predetermined period of time Td starting from the starting control instant of the electric motor 16. In this way, the Measurement step E21 of the first intensity value 11 passing through the electric motor 16 is carried out after the transient period of starting of the electric motor 16 during which fluctuations of the intensity value 1 can be generated. Thus, the first intensity value 11 measured, during the measurement step E21, is reliable for starting the determination of the presence or absence of an obstacle or a limit switch during winding of the screen 2 or during the course of the screen 2. By way of non-limiting example, the predetermined period of time Td, starting from the starting control moment of the electric motor 16, is of the order 300 milliseconds.
    [0024] In one embodiment, the starting command of the electric motor 16 corresponds to the switching of the control switches 24 of the electric motor 16. Then, the control method comprises one or more additional measurement steps E22 of another value of intensity 12, 13, 14, 15 passing through the electric motor 16 by the measuring device 28, following the implementation of the measuring step E21, as illustrated in FIG. 6. Here and in no way In a limiting manner, the control method comprises four additional measuring steps E22 of four other intensity values 12, 13, 14, 15 passing through the electric motor 16 by the measuring device 28 following the implementation of the measurement step. E21.
    [0025] Advantageously, the additional measurement steps E22 of another intensity value 12, 13, 14, 15 are periodically implemented following the implementation of the measurement step E21. By way of non-limiting example, the additional measurement steps E22 are implemented successively with a periodicity of the order of 5 milliseconds.
    [0026] Preferably, the number of additional measuring steps E22 of another intensity value 12, 13, 14, 15 by the measuring device 28 is dependent on the rotational speed of the output shaft 20 of FIG. the electromechanical actuator 11. Thus, the adaptation of the number of additional measurement steps E22 as a function of the speed of rotation of the output shaft 20 of the electromechanical actuator 11 makes it possible to implement the acquisition of the Intensity values 11, 12, 13, 14, 15 at the same periodicity. By way of non-limiting example, the number of additional measurement steps E22 is four for a speed of rotation of 17 revolutions per minute of the output shaft 20 of the electromechanical actuator 11, and nine for a speed 8 rpm of the output shaft 20 of the electromechanical actuator 11. Practically, the number of additional measurement steps E22 of another intensity value 12, 13, 14, 15 follows a linear law as a function of the speed of rotation of the output shaft 20 of the electromechanical actuator 11. The control method then comprises a step E23 determination of a change in the intensity value 1 through the electric motor 16 through the measuring steps E21, E22 intensity values 11, 12, 13, 14, 15. Here, the determination step E23 is implemented by means of the electronic control unit 15, and in particular the microcontroller 27 of the electronic unit control 15.
    [0027] The control method also comprises a determination step E24 of a difference in intensity A1 with respect to the first intensity value 11 measured, following the lapse of a period of time At starting from the first measured intensity value 11, as illustrated in FIG. 7. The period of time At extends between the measurement instant of the first intensity value 11 and the instant of determination of the deviation d intensity A1 with respect to the first intensity value 11 measured. In one embodiment, the period of time At corresponds to a travel length of travel of the screen 2, or in other words to a position reached by the end plate 8 of the screen 2.
    [0028] The displacement length of the screen 2 can be determined, in particular, as a function of the angle of rotation of the winding tube 4, and in particular by one or more sensors of the electric motor 16 making it possible to determine the rotation angle of the rotor. Here, the determination step E24 is carried out by means of the electronic control unit 15, and in particular the measuring device 22 and the microcontroller 27 of the electronic control unit 15. Advantageously, the the control method implements the determination step E24 of an intensity difference A1 with respect to the first intensity value 11 measured, when an increase in the intensity value 1 passing through the electric motor 16 is determined during the determination step E23. Thus, the control method only implements the determination step E24 if an increase of the intensity value 1 is determined on the basis of the measuring steps E21, E22. In this way, the first measured intensity value 11 corresponds to a reference intensity value as soon as an increase in the intensity value 1 passing through the electric motor 16 is determined. In addition, the determination of an increase in the intensity value 1 crossing the electric motor 16 makes it possible to trigger the monitoring of the presence or absence of an obstacle or a limit switch by the detection device 27, from the instant 15 of the first intensity value 11 measured. Furthermore, the determination step E24 of an intensity difference A1, with respect to the first intensity value 11 measured, is carried out only, following the determination of an increase in the intensity value 1. passing through the electric motor 16, so as to limit the number of calculations implemented by the electronic control unit 15, and in particular by the microcontroller 27, to minimize the occupancy rate of the resources thereof. The adaptation of the number of additional measurement steps E22 of another intensity value 12, 13, 14, 15 by the measuring device 28 as a function of the rotational speed of the output shaft 20 of the Moreover, the electromechanical actuator 11 makes it possible to take into consideration the same measured first intensity value 11, irrespective of the rotational speed of the output shaft 20 of the electromechanical actuator 11. In one embodiment, the determination of the increase of the intensity value 1 passing through the electric motor 16 is carried out by a substep of comparison of the intensity values 11, 12, 13, 14, 15 measured and, in particular, by 30 successive iterations of the last intensity value measured with respect to the previously measured intensity value. Here, during the determination step E23, the first intensity value 11 measured during the measurement step E21 is compared with the first other intensity value 12 measured during the first additional measurement step E22 to determine if the first intensity value 11 measured is less than the first other intensity value 3024177 measured. Then, the first other intensity value 12 measured during the first additional measurement step E22 is compared with the second other intensity value 13 measured during the second additional measurement step E22 to determine whether the first other value of intensity 12 measured is less than the second other intensity value 13 measured. Then, the determination step E23 of an evolution of the intensity value 1 implements similar comparisons for the other intensity values 14, 15 measured. In addition, in the case where a decrease of the intensity value 1 passing through the electric motor 16 is determined, during the determination step E23, the control method implements, again, the measuring step E21 of the first intensity value 11. Thus, the measurement step E21 of the first intensity value 11 is reinitialized if a decrease in the intensity value 1 passing through the electric motor 16 is determined 15 determination step E23. In one embodiment, following the determination step E24 of a difference in intensity A1 with respect to the first measured intensity value 11, the control method comprises a step E28 for determining a change in the intensity intensity difference Al.
    [0029] Here, the determination step E28 is implemented by means of the electronic control unit 15, and in particular the measuring device 22 and the microcontroller 27 of the electronic control unit 15. Preferably, the step E24 determination of a difference in intensity Al with respect to the first measured intensity value 11 is carried out periodically, as long as the result of the determination step E28 of an evolution of the deviation of Al intensity corresponds to an increase in the intensity value 1 through the electric motor 16. By way of non-limiting example, the determination step E24 of a difference in intensity Al with respect to the first intensity value It is implemented every 5 milliseconds, following the measurement instant of the first intensity value 11. Advantageously, the determination step E24 of an intensity difference A1 is implemented from a substep of measurement e E241 another value of intensity lm, IO2, lm through the electric motor 16 by the measuring device 28, following the flow of a period of time At1, At2, At3 starting from the moment measuring the first intensity value 11, then, a comparison sub-step E242 of the other intensity value 1m, 1m, 1m measured with respect to the first intensity value 11 measured . Here, the intensity value 1m corresponds to the difference between the first measured intensity value 11 and the second intensity value 12 measured. The intensity value 1.8.2 corresponds to the difference between the first intensity value 11 measured and the third intensity value 13 measured. Then, the intensity values 1.8 ,, are obtained by similar comparisons with respect to the first intensity value 11 measured. In one embodiment, the measurement sub-step E241 of the other intensity value 1m, I.82, 1m crossing the electric motor 16, allowing the determination of a difference in intensity Al with respect to the first intensity value 11 measured, is implemented according to the periodicity of implementation of the determination step E24 of a difference in intensity Al with respect to the first intensity value 11. Preferably, the step E24 determination of a difference in intensity Al with respect to the first measured intensity value 11 is carried out periodically for a predetermined period of time TL starting from the measuring instant of the first value of intensity 11. Thus, in the case where the predetermined period of time TL has elapsed, without the determination step E24 detecting a difference in intensity Al greater than a threshold value of intensity S predetermined, this means that the method of control resulted in a failure to determine an obstacle or a limit switch during the predetermined time period IL. In addition, in the case where the predetermined period of time TL has elapsed, without the determination step E24 detecting an intensity difference A1 greater than a predetermined intensity threshold value S, the control method implements again the measuring step E21 of the first intensity value 11 passing through the electric motor 16. In one embodiment, the determining step E24 of an intensity difference A1 with respect to the first value of measured intensity 11 is periodically implemented during the predetermined time period TL starting from the measuring instant 30 of the first intensity value 11, when an increase in the intensity value I passing through the electric motor 16 is determined in the determination step E23. Then, the control method comprises a selection step E25 of one of the intensity threshold values S as a function of the period of time At elapsed. Here, the selection step E25 is implemented by means of the electronic control unit 15, and in particular the microcontroller 27 of the electronic control unit 3024177 18 15. Advantageously, the measurement instant of the first intensity value 11, from which the determination step E24 of an intensity difference A1 is implemented, corresponds to an instant of starting an obstacle detection or end of race search according to a predefined detection sensitivity. The predefined detection sensitivity can be selected, in particular, according to the position of the screen 2, or according to an input made by the user through the local control unit 12 or the control unit. 13. Advantageously, the intensity threshold values S stored in the memory of the electronic control unit 15 and used during the selection step E25 are set and follow a predetermined profile between a start time, start time corresponding to the measurement instant of the first intensity value 11, and an end time, the end time corresponding to the end time of the predetermined period of time TL starting from the instant of measurement of the first intensity value 11. Preferably, the intensity threshold value profile S stored in a memory of the electronic control unit 15 and used during step d The selection E25 comprises at least a first phase where the intensity threshold values S are identical during a first predetermined period of time Sa from the measurement instant of the first intensity value 11, and a second phase where the threshold values of intensity S are decreasing during a second predetermined period of time Sb following the first predetermined period of time Sa. Here and in no way limiting, the first predetermined period of time Sa is of the order of 100 milliseconds, and the second predetermined period of time Sb is of the order of 200 milliseconds. The intensity threshold values S of the first phase of the intensity threshold value profile S stored in the memory of the electronic control unit 15 and used during the selection step E25 are identical so as to enable detection. end of travel or a rigid obstacle, such as for example a hard point in the lateral rails 6 during the passage of the blades of the screen 2 therein, or a jamming of the blades of the screen 2 between them, or a jerk during the winding of the or the joints 10 and the upper end plate of the screen 2 around the winding tube 4. The intensity threshold values S of the second phase of the intensity threshold value profile S stored in the memory of the electronic control unit 15 and used during the selection step E25 are decreasing so as to allow the detection of a flexible obstacle. , such as for example the retention of lam es of the screen 2 in the side rails 6 by the gel. The intensity threshold values S of the second phase of the profile are decreasing to a threshold value of minimum intensity Smin. The threshold value of minimum intensity Smin corresponds to a threshold value of intensity S greater than the variation of torque generated by the unsticking of the blades of the screen 2 during the winding of the screen 2 since the low end of the stroke. . The slope of a straight line D connecting the point representative of the first intensity value 11 to the point representing the minimum intensity threshold value S min in FIG. 7 corresponds to the minimum slope of the intensity difference. A1 can be used for the determination of an obstacle by the detection device 27. Advantageously, the control method implements the selection step E25 of one of the intensity threshold values S when an increase of In the determination step E28, the difference in intensity A1 is determined by a change in the intensity difference A1 relative to the first measured intensity value 11. Thus, the control method only implements the selection step E25 if an increase in the intensity difference A1 is determined on the basis of the measuring step E21 of the first intensity value 11 crossing the electric motor 16 and at least one measurement sub-step E241 of another intensity value 1m, batch, law passing through the electric motor 16 implemented during the determination step E24 of a deviation In addition, the selection step E25 of one of the intensity threshold values S is carried out only, following the determination of an increase in the intensity difference Al, so as to limit the number of calculations implemented by the electronic control unit 15, and in particular the microcontroller 27, to minimize the occupancy rate of the resources thereof. In one embodiment, the determination of the increase in the intensity difference A1 is carried out by a comparison sub-step E242 of the measured intensity values 11, 1m, 1m, 1m, and in particular by successive iterations of the last intensity value measured with respect to the previously measured intensity value. Here, during the determination step E28 of an evolution of the intensity difference A1, the comparison of the first intensity value 11 measured during the measurement step E21 with the first other value of 1m intensity measured during the measurement sub-step E241 is analyzed to determine if the first measured intensity value 11 is less than the first other measured intensity value 1m. Then, the comparison of the first other intensity value 1m measured during the first measurement sub-step E241 with a second other intensity value 1m measured during a second measurement sub-step E241 is analyzed to determine if the first other intensity value 1m measured is less than the second other intensity value 1m measured. Then, the determination step E28 of an evolution of the intensity difference A1 analyzes similar comparisons for other measured intensity values 1.8 ,,, as long as an increase in the difference of intensity Al is determined and that the predetermined period of time TL has not elapsed. Furthermore, in the case where a decrease in the intensity difference A1 is determined, during the determination step E28 of an evolution of the intensity difference A1, the control method again implements the measuring step E21 of the first intensity value 11 passing through the electric motor 16. Thus, the measuring step E21 of the first intensity value 11 passing through the electric motor 16 is reset if a decrease in the Intensity deviation A1 is determined in the determination step E28 of an evolution of the intensity difference A1. The control method then comprises a comparison step E26 of the intensity difference. Al determined with respect to the selected intensity threshold value S, and a determination step E27 of the presence or absence of an obstacle or a limit switch as a function of the result of the comparison step E26. Here, the comparison step E26 and the determination step E27 are implemented by means of the electronic control unit 15, and in particular the microcontroller 27 of the electronic control unit 15. The presence of an obstacle or a limit switch is determined when the determined intensity difference A1 is greater than or equal to the selected intensity threshold value S. And the absence of an obstacle or a limit switch is determined when the determined intensity difference A1 is smaller than the intensity threshold value S selected.
    [0030] The monitoring of the torque generated by the electric motor 16 of the electromechanical actuator 11 through the measurement of the intensity 1 passing through the electric motor 16 by the measuring device 28 makes it possible to guarantee the reliability of determination of absence or of presence of an obstacle or an end of race. The use of the measurement of the intensity 1 passing through the electric motor 16 makes it possible to guarantee the reactivity of determination of the absence or presence of an obstacle or of a limit switch and to get rid of Measurement uncertainties related to a measurement chain with one or more sensors. The use of the intensity measurement I through the electric motor 16 to perform the intensity measurements 11, 12, 13, 14, 15, 1m, 1m, 1m makes it possible to determine a sampling frequency as a function of the desired accuracy of determination of absence or presence of an obstacle or a limit switch. This sampling frequency of the intensity 1 passing through the electric motor 16 is thus independent of the voltage of the power supply network of the sector, and in particular of its frequency.
    [0031] Preferably, the determination step E24 of an intensity difference A1 with respect to the first measured intensity value 11 is carried out periodically, as long as the result of the determination step E27 of presence or of absence of an obstacle or a limit switch is different from an obstacle or a limit switch detected. Advantageously, the control method also comprises a determination step El 1 of the direction of rotation of the output shaft 20 of the electric motor 16, a determination step E12 of the position of the screen 2 of the occulting device 3 and a determination step E13 of several portions of the movement of movement of the screen 2, during the winding of the screen 2 and during the unfolding of the screen 2. In a first embodiment, at least the determination steps E24 of a difference in intensity A1, of selection E25 of one of the intensity threshold values S, of comparison E26 of the intensity difference A1 determined with respect to the intensity threshold value. S selected and E27 determination of presence or absence of an obstacle or a limit switch are implemented during at least a portion of the movement of displacement of the screen 2, during the winding of the screen 2 or during the scrolling of the screen 2. In such a case, these steps E24, E25, E26, E27 for determining the presence or absence of an obstacle or a limit switch are implemented during a portion of the travel path of the 2, following the implementation of steps E11, E12, E13 for determining the position of the screen 2 during a movement thereof caused by the electromechanical actuator 11. This first embodiment is, preferably, implemented following the determination of the upper and lower end limit stops for delimiting the displacement path of the screen 2 of the occulting device 3. The determination of the stops of the high and low limit switches can be implemented either automatically or manually. The determination of the end stops of high and low stroke automatically is implemented, when commissioning the home automation system, by a sequence of movements of the screen 2 until the detection of an obstacle at the top of the home automation system and until an obstacle is detected at the bottom of the home automation system. The determination of the 5 stops of high and low limit switches manually is implemented, when commissioning the home automation system, by moving the screen 2 to a high position defined by the user by pressing, for example, a button on the remote control 14, and even to a low position. Advantageously, at least the determination steps E24 of an intensity difference A1, of selection E25 of one of the intensity threshold values S, of comparison E26 of the intensity difference A1 determined with respect to the threshold value of intensity S selected and determination E27 of presence or absence of an obstacle or a limit switch are implemented during a start portion of the movement of movement of the screen 2 during winding of the screen 2 or during its unwinding, 15 following the reaching of a limit switch. In such a case, during one or more other portions of the displacement path of the screen 2, the intensity threshold value S is fixed. Thus, during the other portion or portions of the displacement path of the screen 2, the intensity threshold value S is independent of the time period ΔT elapsed from the first intensity value 11 measured. Preferably, the fixed intensity threshold value S of the other portion or portions of the displacement path of the screen 2 is less than or equal to the smallest of the intensity threshold values S used during the start portion of the movement of movement of the screen 2.
    [0032] Thus, the determination of the presence or absence of an obstacle or an end of travel by the detection device 27 is implemented with a relatively high threshold of sensitivity during the other portion or portions of the race. 2. Advantageously, the other portion (s) of the displacement path of the screen 2 correspond, in particular, to the docking zones on the upper and lower limit switches. In addition, the determination of the presence or absence of an obstacle or of an end of travel by the detection device 27 is implemented with a low sensitivity threshold during the start portion of the travel movement of the screen 2, so as to avoid inadvertent tripping of the detection device 27 causing the stopping of the motorized drive device 5. In a second embodiment, at least the E24 determination steps of a deviation of intensity A1, of selection E25 of one of the intensity threshold values S, of comparison E26 of the intensity difference A1 determined with respect to the selected intensity threshold value S and presence determination E27. or absence of an obstacle or a limit switch are implemented throughout the movement of movement of the screen 2, during the winding of the screen 2 or during its course. In such a case, these steps E24, E25, E26, E27 making it possible to determine the presence or the absence of an obstacle or a limit switch are implemented over the total length of the travel path of the vehicle. 2. This second embodiment is preferably implemented during the installation of the concealment device 3, and in particular before the determination of the stops of the upper and lower limit stops for delimiting the displacement stroke. of the screen 2 of the occulting device 3.
    [0033] Advantageously, the first measured intensity value 11, the other intensity value or values 1m, 1m, 1m measured making it possible to determine a difference in intensity A1 with respect to the first intensity value 11 measured and the determining an evolution of the intensity difference A1 with respect to the first intensity value 11 measured, as well as the other intensity value or values 12, 13, 14, 15 measured, allowing the determination of a Intensity value 1 passing through the electric motor 16 is stored temporarily in a buffer memory of the electronic control unit 15, and in particular the microcontroller 27. Thanks to the present invention, the control method makes it possible to determine the whether or not the travel ends of the screen travel, as well as the presence or the absence of an obstacle by the monitoring of intensity deviations with respect to a first intensity value crossing the screen; electric motor. In this way, the control method makes it possible to determine the presence or the absence of an obstacle or a limit switch dynamically by comparing intensity differences determined from a first intensity value passing through. the electric motor with respect to a selected intensity threshold value as a function of the period of time elapsed between the measurement time of the first intensity value and the instant of determination of an intensity difference. Consequently, the control method makes it possible to guarantee the protection of the motorized drive device as well as the home automation installation, while limiting the untimely stops of displacement of the screen of the occulting device.
    [0034] The present invention also provides a computer program product comprising code instructions arranged to implement the steps of the control method according to the invention, as described above. In addition, the electronic control unit includes the microcontroller. The microcontroller includes in memory the code instructions of the computer program product. And the electronic control unit is configured to at least determine an intensity difference, select one of the intensity threshold values, compare the intensity difference determined with respect to the selected intensity threshold value and determine the presence or absence of an obstacle or an end of race.
    [0035] Many modifications can be made to the embodiments described above without departing from the scope of the invention. In particular, the electric motor of the electromechanical actuator may be of the asynchronous three-phase or DC type. In addition, the contemplated embodiments and alternatives may be combined to generate new embodiments of the invention.
