Description

The present invention relates to a motorized system for concealment or closure of a multi-control building opening, as well as to a motorized system for concealment or closure of a multi-control building opening, as well as a motorized system for concealment or closure of a multi-control building opening. a modular electronic control device of said system. The modular control device is intended to actuate opening or closing said system. The invention finds particular application to the actuation of motorized roller shutter type systems, or window or bay window. Generally, to power such systems concealment or closure of a building opening, can be used an electronically controlled motor, whose commands are transmitted either wired or non-wired.

In the case where the control is carried out by non-wired means (see FIG. 1 a), for example by radio radio waves, the device is permanently powered (wire 20 for the neutral, wire 21 for the earth, wire 24 for the phase of the mains supply), and comprises a radio component disposed in the control electronics 26 and adjusted to a given frequency. The device receives actuation commands in the form of radio frames from a remote control. A control organ, generally of microcontroller type, arranged in the control electronics 26, interprets these frames to actuate the motor 25 in one or other of its two directions of rotation. One of the problems with this type of control is that it can be prohibited in some places where radio transmission is prohibited. This is the case, for example, in an establishment such as a hospital, in which radio transmissions can disrupt the operation of certain medical devices and are therefore prohibited. Traditionally, in a control device of a wired electronically controlled motor, called wired electronic motor, the power cables also serve as control. This type of device, as shown in FIG. 1b, generally comprises four wires: a wire 20 for the neutral, a wire 21 for the ground, a wire 22 for the first direction of rotation, and a wire 23 for the second direction of rotation. The contacting of the wire 21 with the phase of the power supply 24 actuates the motor 25 in a first direction of rotation, and the contacting of the wire 22 with the phase of the power supply 24 actuates the motor 25 in the second direction of rotation. One of the problems with this type of configuration is that the control electronics are not permanently powered, and therefore no longer able to handle mechanical phenomena such as brake slippage.

Such phenomena, however, disturb the proper functioning of the system and must be appropriately managed by the electronics. For example, when a brake slip occurs, it is necessary that the electronics can perform a registration so that the system continues to properly perform its function of concealment or closure of the opening in the building .

To solve this type of problem, it is possible to use a wired control of another type (see FIG. 1c), in which the control electronics 26 remains permanently powered, but in which the power cables (wire 20 for the neutral and live wire of the power supply 24) are not used for control. In this example, the command can be activated by contacting two input lines 22, 23 (for example by means of a push-button 27). The control electronics 26 interprets successive actuations of the push button 27 for the rotation of the motor 25 in one direction or the other. Thus, for example, a first action on the pushbutton 27 is detected by the control electronics 26 which actuates the motor 25 in a first direction of rotation. A second action on the pushbutton 27 detected by the control electronics 26 then stops the rotation of the motor 25. Finally a third action on the push button 27 actuates the motor 25 in the second direction of rotation.

Furthermore, certain uses require that all the controls be centralized on various very low voltage type control devices, such as for example devices for telethesis or home automation type systems. Very low voltage (or TBT) means a voltage that is less than or equal to 50 V.

The electronic control unit, generally of the electronic card type, then comprises a power supply module for supplying TBT to the various functional modules included in this control electronics. The control itself therefore does not require power supply, and can therefore be controlled by a dry contact.

However, especially in case of mounting in a renovated configuration in which it is necessary to adapt to the environment, the use of a wired type of control, as opposed to the radio type control, sometimes causes wiring problems difficult to solve, both technically and aesthetically, when it comes to installing an occultation system in an environment where wiring was not originally planned. It is therefore not possible or practical to be limited to a single type of command, whether wired or wireless, for all uses. A user is therefore led to choose a specific device among the different types of existing devices. The object of the invention is therefore to provide a solution to the aforementioned problems among other problems, by proposing a motorized system for concealing or closing a multi-control building opening and a control device. corresponding modular. The invention thus relates, in a first aspect, to a control device for a motorized system for occultation or closure of a building opening, such as a shutter, a window or a bay window, comprising a motor with two directions of rotation. The device comprises an electronic control unit adapted to receive an input of an actuation command of the motor and to control it in one or the other of the two directions of rotation according to the actuation command.

The electronic control unit further comprises a power supply module, and a control module which can itself include a microcontroller. The control module is able to interpret the actuation command 5 to control the motor, and is electrically powered by the power supply module. Typically, the electronic control unit comprises at least two modules for receiving the actuation command, each of these modules being able to transmit this actuation command to the control module. The control module is also able to interpret this operation command regardless of the receiving module used to receive the command. Thus, the device of the invention is flexible and allows to control a motorized system of occultation or closure of building in multiple ways, so that the device can be used in an installation independently of the constraints of environment of use , by activating one or more of the receiving modules. In a first variant embodiment, at least one of the reception modules of the actuation command is a module for receiving this command via a non-wire channel. In a second variant embodiment, possibly in combination with the first, at least one of the reception modules of the actuation command, is a module for receiving this command by wire route. In this case, the reception module of the actuation control comprises at least one input, this input being electrically powered by the power supply module. Preferably, this receiving module of the wired control 30 comprises a single input. This input comprises two control lines, and can be activated by connecting these two control lines via a connection means with dry contacts, such as a push button. By means of connection with dry contacts means connecting means that does not require power. The receiving module of the wired control may also include at least two inputs. These inputs each comprise a clean command line and a common control line, and are each activatable by connection of their respective own command lines with the common control line via one or more dry contact connection means. , such as one or more switches and / or pushbuttons. Other variants are presented hereinafter, which may be considered alone or in combination with one or more of the other variants. Thus, in operation, the power supply module is connected to an external power source, and the electronic control unit is permanently electrically powered, regardless of the receiving module used to receive the actuation command. The power supply module can be a very low voltage power supply module. Also, the electronic control unit may comprise a multiple command management module, able to select an actuation command from among several actuation commands transmitted respectively by several of the receiving modules. This management module may or may not be implemented in the control module. Thus, when several reception modules are active, if the electronic control unit receives several actuation commands via the different reception modules, the multiple command management module decides that the control module control must interpret, for example according to a predetermined order of priority. The invention also relates, in a second aspect, to a motorized system for concealing or closing a building opening, such as a shutter, a window or a bay window, comprising a two-way motor. of rotation. Typically, the system comprises a control device as presented above.

Thus, the motor is electrically powered permanently, regardless of the receiving module used to receive the actuation command. Other features and advantages of the invention will appear more clearly and completely on reading the following description of the preferred embodiments, which are given by way of non-limiting examples and with reference to the following appended figures: FIGS. 1a, 1b, 1c show diagrammatically examples of control device according to the state of the art; FIG. 2 schematically represents an example of a control device of the invention.

In the exemplary embodiment shown in FIG. 2, the device therefore comprises an electronic control unit 2, which can take the form of an electronic card, or comprise such an electronic card, on which the various functions fulfilled by the device. This electronic control unit 2 is intended to control the engine 1 of a system such as a shutter, that is to say to rotate this engine 1 in one or other of its two directions of rotation. In operation for the control of the roller shutter, the rotation of the motor 1 in a first direction causes the deployment of the apron, therefore the closure of the shutter, and the rotation of the motor 1 in the second direction of rotation 25 causes the folding of the apron, therefore the opening of the shutter. A power interface 12 or power control 12 is provided in the electronic control unit 2 for the transmission of the command to the engine 1. The electronic control unit 2 furthermore comprises a control logic unit or control module 3. A control module 3 consisting of or comprising a microcontroller is preferably used. This control module 3 is capable of interpreting and transmitting an actuation command of the engine 1 in one or the other of the two directions of rotation of this engine 1, and is powered by a power supply module 4.

It can also be provided in the electronic control unit 2, a module 13 for electronic management of the position of the motorized element, possibly associated with sensors, such as mechanical limit sensors, whose role is to correctly manage the stroke of the closing element of the motorized system.

This module 13 for electronic management of the position of the motorized element, which may or may not be implemented in the control module 3, is also powered by the power supply module 4. According to the invention, the electronic unit of command 2 is able to receive as input an actuation command of the engine 1, this actuation command being interpreted by the control module 3 to control the engine 1. For the reception of the actuation command, the electronic unit control 2 integrates at least two reception modules. In the example shown in FIG. 2, the electronic control unit 20 comprises four modules 5, 6, 8 and 16 for receiving the actuation command. The first module 5 for receiving the actuation command is a reception module by non-wire way, for example by radio waves type air. This first reception module 5 is able to receive an actuation command in the form of a radio frame originating, for example, from a remote control. This radio frame is transmitted to the control module 3 which interprets it to actuate the engine 1 in one or the other of its two directions of rotation. The second module 6 for receiving the actuation command is a wired reception module.

In the example shown in FIG. 2, the wired reception module 6 comprises a single input 7 powered by the power supply module 4, preferably of the very low voltage type (TBT). This input 7 can be activated by contacting or connecting two control lines 7a, 7b. This contacting of the two control lines 7a, 7b, one of which 7b comes from the power supply module 4, can be obtained by a connection means 14 with dry contacts such as a push button 14. When this push button 14 is pressed a first time, the control module 3 detects the contact between the two control lines 7a and 7b and triggers the rotation of the motor 1 in a first direction of rotation. A second pressure on the push button 14 detected by the control module 3 causes the rotation of the motor 1 to stop in the first direction of rotation. A third pressure on the push button 14 detected by the control module 3 causes the rotation of the motor 1 in the second direction of rotation. Finally, a fourth pressure on the push button 14 detected by the control module 3 causes the rotation of the motor 1 to stop in the second direction of rotation. Preferably, at the installation, predetermined combinations of connection and disconnection cycles of the two control lines 7a and 7b, possibly taking into account the duration of the connection or disconnection periods, make it possible to switch to different operation, such as setting modes of the limit switches, adjusting the sensitivity, resetting the parameters of the engine 1, etc ... The third module 8 for receiving the actuation command is also a reception module by wire route. In the example shown in FIG. 2, this wired reception module 8 comprises two inputs 9 and 10 powered by the electrical power supply module 4, preferably of the very low voltage type (TBT). The first input 9 comprises a clean control line 9a and a control line 11 common to the two inputs 9 and 10. The second input 10 furthermore comprises an own control line 10a and the control line 11 common to the two inputs 9 and 9. Each input 9 and 10 is electrically powered via the common control line 11, so that when this common control line 11 is brought into contact with one or the other of the two own control lines. 9a and 10a, the control module 3 detects one of the contacts and thus interprets the actuation command of the motor 1 in one or other of the two directions of rotation or stopping of the motor.

The contacting of the common control line 11 with one or the other of the two clean control lines 9a, 10a can be obtained by a connection means 15 with dry contacts such as a switch or a push-button. for each input 9 and 10, or a common rocker switch type switch 15.

Preferably, at the installation, predetermined combinations of connection and disconnection cycles of the common control line 11 with the two clean control lines 9a and 10a make it possible to switch to different operating modes, as explained above. with reference to the module 6 for receiving the wired actuation command. The fourth module 16 for receiving the actuation command is also a wired reception module. In the example shown in FIG. 2, this wired reception module 16 comprises three inputs, all referenced by the same reference 17 for the sake of clarity, powered by the electrical power supply module 4, preferably of a very small type. low voltage (TBT). The first input of the group of inputs 17 comprises a clean command line 17a and a command line 18 common to the three inputs. The second input of the input group 17 includes a clean command line 17b and the command line 18 common to the three inputs. Finally, the third input of the input group 17 includes an own control line 17c and the control line 18 common to the three inputs.

Each input of the input group 17 is electrically powered via the common control line 18, so that when this common control line 18 is brought into contact with one or the other of the three command lines 17a, 17b, 17c, the control module 3 detects one of the contacts and thus interprets the actuation control of the engine 1 in one or the other of the two directions of rotation or stopping of the engine. The contacting of the common control line 18 with one or the other of the three own control lines 17a, 17b, 17c can be obtained by respective connection means 19a, 19b, 19c with dry contacts, such as switches or pushbuttons. Preferably, at the installation, predetermined combinations of connection and disconnection cycles of the common control line 18 with the three clean control lines 17a, 17b, 17c make it possible to switch to different operating modes, as explained. higher with reference to the module 6 for receiving the wired actuation command. Whatever the module 5, 6, 8, 16 of reception actually used for the reception of an actuation command, the electronic control unit 2 remains electrically powered permanently, via the power supply module 4 , itself connected, in operation, to an external power supply source 30. As explained above, the device of the invention comprises several modules 5, 6, 8, 16 for receiving the actuation command. For the device to operate, that is to say, so that it can control the motor 1, it is necessary that at least one of the modules 5, 6, 8, 16 for receiving the actuation command is activated. to be in service. The activation or deactivation of a given reception module is obtained by adapting the software code implemented in the control module 3. Thus, the device of the invention always has at least two reception modules of the actuation command. On installation, as necessary, the device can operate with only one of the receiving modules 5, 6, 8, 16, or any combination of these receiving modules. In the case of a device with multiple commands, capable of receiving as input multiple actuation commands transmitted to the control module 3 by several modules 5, 6, 8, 16 for receiving a command, provision is made in the electronic control unit 2 a multiple control management module (not shown in Figure 2). This multi-command management module notably has the role of managing conflicts and control priorities of actuation. It is thus particularly suitable for selecting an actuation command from among all the actuation commands received, so that the control module 3 can interpret this actuation command to appropriately control the setting in rotation or the stopping of the rotation of the engine 1. This module for managing multiple commands may for example be implemented directly in the control module 3.

The present description is given by way of example and is therefore not limiting of the invention. In particular, it will be recalled that the exact number of reception modules of an actuation command is not limiting of the invention, provided that there are at least two receiving modules of the actuation command, whose at least one by wire preferably. Furthermore, the electronic control unit 2 may comprise other modules for the implementation of other functions than those described with respect to the example shown in Figure 2, as needed.
