Description

Title of the invention: Method for controlling the operation of a screening installation and associated screening installation

[0001] The present invention relates to a method for controlling the operation of a screening installation.

[0002] The present invention also relates to a concealment installation adapted to implement this control method.

[0003] Generally, 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 at least a second position.

[0004] A motorized drive device comprises an electromechanical actuator of a movable closing, concealing or sun protection element, such as a shutter, a door, a grille, a blind or any other equivalent material, hereinafter called a screen.

[0005] Document WO 2011 / 151308 A1 is already known, which describes a method for configuring a screening installation for a building. The screening installation comprises a screening device, a window, and a sensor. The sensor, in particular a microphone, is configured to measure an acoustic signal. The screening device comprises a screen and a motorized drive device. The screen is configured to move opposite the window. The motorized drive device comprises an electromechanical actuator and an electronic control unit. The electromechanical actuator is configured to move the screen. The electromechanical actuator comprises an electric motor and an output shaft. The electric motor is configured to be controlled by the electronic control unit. The output shaft is configured to be rotated according to several rotation speed setpoints by the electric motor. The method comprises a step of measuring an acoustic signal to detect the reaching of an end-of-travel position of the screen against a stop or to detect the presence of an obstacle during the movement of the screen, by processing this signal. The method further comprises a step of adjusting a speed setpoint of the actuator in a limited range in the vicinity of a predetermined target value automatically, using the measurement of the acoustic signal. This method is generally satisfactory.

[0006] However, this concealment installation has the disadvantage that the microphone is arranged inside the motorized drive device, in particular inside the electromechanical actuator or the electronic control unit, or on an apron of a roller shutter, constituting the screen of the concealment device.

[0007] Consequently, this adjustment method is defined to measure an acoustic signal coming from the occulting device, either when the screen reaches an end-of-travel stop, or when the screen encounters an obstacle during its movement, in order to adapt a speed setpoint of the electromechanical actuator as a function of this event occurring during the control of the electromechanical actuator. This adjustment method does not make it possible to detect an ambient noise level inside a room of the building before the control of the electromechanical actuator, nor to control a rotation speed setpoint of the output shaft of the electromechanical actuator as a function of this ambient noise level detected inside the room of the building.

[0008] The present invention aims to resolve the aforementioned drawbacks and to propose a method for controlling the operation of a blackout installation for a building, as well as a blackout installation for a building, making it possible to control a rotation speed setpoint of an output shaft of an electromechanical actuator belonging to the blackout installation as a function of an ambient noise level inside a room of the building.

[0009] In this regard, the present invention aims, according to a first aspect, at a method for controlling the operation of a blackout installation for a building,

[0039] - a step of incrementing a counter at each occurrence of the execution of the modification step,

[0040] - a second step of comparing the value of the incremented counter, during the increment step, relative to at least one predetermined increment threshold value, and

[0041] - depending on the result of the first and second comparison steps,

[0223] Advantageously, the first sensor 25 comprises at least one second communication module 36, such as that described with reference to the local control unit 12 or to the central control unit 13. Furthermore, the second communication module 36 of the first sensor 25 is configured to communicate, in other words communicates, with the first communication module 27 of the electronic control unit 15.

[0224] Advantageously, in the case where the building B comprises a plurality of rooms P, the occultation installation 6 comprises a first sensor 25 arranged inside each of the rooms P of the building B, so as to implement the method for controlling the operation of the occultation installation 6 described below.

[0225] Advantageously, the occultation installation 6 further comprises at least one second sensor 31. The second sensor 31 is configured to detect, in other words detects, a presence of at least one user. In addition, the second sensor 31 is located inside room P of building B.

[0226] Advantageously, the second sensor 31 comprises at least one second communication module 36, such as that described with reference to the local control unit 12 or to the central control unit 13. Furthermore, the second communication module 36 of the second sensor 31 is configured to communicate, in other words communicates, with the first communication module 27 of the electronic control unit 15.

[0227] Advantageously, in the case where the building B comprises a plurality of rooms P, the occultation installation 6 comprises a second sensor 31 arranged inside each of the rooms P of the building B, so as to implement the method for controlling the operation of the occultation installation 6 described below.

[0228] Here and as visible in [Fig.2], the first and second sensors 25, 31 are separate entities arranged in the part P.

[0229] As a variant, not shown, the first sensor 25 and the second sensor 31 are integrated into the same housing.

[0230] A method of executing a method for controlling the operation of the occultation installation 6, shown in FIGS. 1 and 2, in accordance with the invention, is now described with reference to [Fig. 5]. In other words, the method is a method for operating the occultation installation 6 or a method for managing the occultation installation 6.

[0231] The operating control method comprises a step E20 of measuring at least one value of the noise level NB inside the room P of the building B by the first sensor 25.

[0232] The method further comprises a first comparison step E40 of the noise level value NB measured, during the measurement step E20, with respect to at least one predetermined threshold value of noise level SNB.

[0233] The method further comprises a step E70 of controlling the electromechanical actuator 1 according to a rotation speed setpoint CV1, CV2, CV3 of the output shaft 20 selected, as a function of the result of the first comparison step E40, from among the rotation speed setpoints CV1, CV2, CV3 of the output shaft 20, in particular the first rotation speed setpoint CV1, the second rotation speed setpoint CV2 or, possibly, the third rotation speed setpoint CV3 of the output shaft 20.

[0234] Thus, the method makes it possible to control the electromechanical actuator 11 by selecting the rotation speed setpoint CV1, CV2, CV3 of the output shaft 20, from among a plurality of rotation speed setpoints CV1, CV2, CV3 of the output shaft 20, as a function of the value of the ambient noise level NB measured inside the room P of the building B.

[0235] Advantageously, when the measured noise level value NB, during the measurement step E20, is strictly less than the predetermined noise level threshold value SNB, the control step E70 is implemented by selecting the first rotation speed setpoint CV1 of the output shaft 20. Furthermore, when the measured noise level value NB, during the measurement step E20, is greater than or equal to the predetermined noise level threshold value SNB, the control step E70 is implemented by selecting the second rotation speed setpoint CV2 of the output shaft 20.

[0236] Thus, when the noise level value NB is high, in other words greater than or equal to the predetermined threshold noise level value SNB, the electromechanical actuator 11 is controlled according to a rotation speed setpoint of the output shaft 20 greater than that used when the noise level value NB is low, in other words strictly less than the predetermined threshold noise level value SNB.

[0237] Advantageously, the method further comprises, prior to the control step E70, a step E60 of detecting the presence of at least one user U inside the room P of the building B by the second sensor 31. When a single user U is detected as being present inside the room P of the building B, during the detection step E60, the control step E70 is implemented by selecting the first rotation speed setpoint CV1 of the output shaft 20, regardless of the measured noise level value NB, during the measurement step E20. Furthermore, when no user U is detected as being present inside the room P of the building B, during the detection step E60, the control step E70 is implemented by selecting the second rotation speed setpoint CV2 of the output shaft 20, regardless of the measured noise level value NB, during the measurement step E20.

[0238] Thus, when a single user U is detected as being present inside the room P of the building B, the electromechanical actuator 11 is controlled according to a rotation speed setpoint of the output shaft 20 lower than that used when no user U is detected as being present inside the room P of the building B.

[0239] Advantageously, when several users U are detected as being present inside the room P of the building B, during the detection step E60, the control step E70 is implemented by selecting the second rotation speed setpoint CV2 or, possibly, the third rotation speed setpoint CV3 of the output shaft 20, in particular as a function of the measured noise level value NB, during the measurement step E20.

[0240] Thus, when several users U are detected as being present at inside the room P of the building B, the electromechanical actuator 11 is controlled according to a rotation speed setpoint of the output shaft 20 higher than that used when a single user U is detected as being present inside the room P of the building B.

[0241] Furthermore, when several users U are detected as being present inside the room P of the building B, the electromechanical actuator 11 is controlled according to a rotation speed setpoint of the output shaft 20 which is either identical to that used when no user U is detected as being present inside the room P of the building B, or higher or lower than that used when no user U is detected as being present inside the room P of the building B, depending on the measured noise level value NB, during the measurement step E20.

[0242] Alternatively, when several users U are detected as being present inside the room P of the building B, the electromechanical actuator 11 can be controlled according to one of the first, second or, possibly, third rotation speed setpoints CV1, CV2, CV3 of the output shaft 20 which is defined as a function of a determination of the nature of the room P of the building B, such as, for example, a work area or a living room, and, preferably, as a function of the noise level value NB measured, during the measurement step E20. The determination of the nature of the room P of the building B can be implemented by a selection through the selection elements 14 of the local control unit 12 or of the central control unit 13.In the case where the rotational speed setpoint of the output shaft 20 is independent of the measured noise level value NB, during the measurement step E20, a value of the rotational speed setpoint of the output shaft 20 can be predetermined, in particular by a selection through the selection elements 14 of the local control unit 12 or of the central control unit 13.

[0243] Advantageously, when several users U are detected as being present inside the room P of the building B, during the detection step E60, and when the noise level value NB measured, during the measurement step E20, is strictly lower than the predetermined noise level threshold value SNB, the control step E70 is implemented by selecting the first rotation speed setpoint CV1 of the output shaft 20. Such a case may correspond, for example, to a situation where several people are present in the same work area with a calm atmosphere.

[0244] Advantageously, when several users U are detected as being present inside the room P of the building B, during the detection step E60, and when the noise level value NB measured, during the measurement step E20, is su lower than or equal to the predetermined noise level threshold value SNB, the control step E70 is implemented by selecting the second rotation speed setpoint CV2 or, possibly, the third rotation speed setpoint CV3 of the output shaft 20. Such a case may correspond, for example, to a situation where several people are present in the same living room of a house.

[0245] Advantageously, the method further comprises, prior to the measurement step E20, a first step E10 of receiving a control order OC originating from the local control unit 12, from the central control unit 13 or from the other sensor 37. Furthermore, following the measurement step E20 and prior to the first comparison step E40, the method comprises a second step E30 of receiving the noise level value NB measured, during the measurement step E20.

[0246] Advantageously, the method further comprises, following the first reception step E10 and prior to the control step E70, a step E50 of determining a TOC type of the control order OC received, during the first reception step E10, either automatic or manual. Furthermore, the control step E70 is implemented by also taking into consideration the TOC type of the control order OC determined, during the determination step E50.

[0247] Thus, the selection of the rotation speed setpoint of the output shaft 20 is implemented by taking into account the measured noise level value NB, during the measurement step E20, and the TOC type of the determined control order OC, during the determination step E50.

[0248] An automatic type OC control order is a control order issued by the local control unit 12, by the central control unit 13 or by the other sensor 37 according to a predetermined scenario, in other words without intervention by a user U.

[0249] A manual type control order OC is a control order issued by the local control unit 12 or by the central control unit 13 in response to an activation of the or one of the selection elements 14 of the local control unit 12 or of the central control unit 13, in other words following an intervention by a user U.

[0250] Advantageously, in the case where the control order OC is said to be “automatic”, the control step E70 is implemented according to the predetermined rotation speed setpoint CV1, CV2, CV3 of the output shaft 20, as a function of the measured noise level value NB, during the measurement step E20 and, possibly, as a function of the detection of the presence of one or more users U inside the room P of the building B.

[0251] Advantageously, in the case where the control order OC is said to be “manual”, the control step E70 is implemented either according to the rotation speed setpoint CV1, CV2, CV3 of the output shaft 20 predetermined, as a function of the measured noise level value NB, during the measurement step E20 and, possibly, as a function of the detection of the presence of one or more users U inside the room P of the building B, either according to a rotation speed setpoint CV1, CV2, CV3 of the output shaft 20 predetermined according to a preference of the user(s) U, in particular by a selection through the selection elements 14 of the local control unit 12 or of the central control unit 13.
