EP2239409A2 - Motorised system for concealing or closing an opening in a building with multiple controls and corresponding modular control device - Google Patents

Abstract

The device has an electronic control unit (2) i.e. electronic board, receiving an actuation control for actuating a motor (1) and controlling the motor according to the actuation control. The control unit has actuation control receiving modules (5-8, 16) for receiving the actuation control, and transmits the actuation control to a control module (3). The control module interprets the actuation control for controlling the motor irrespective of the receiving module used for receiving the actuation control. An independent claim is also included for a motorized concealing or closing system for an opening in a building.

Description

The present invention relates to a motorized system for concealing or closing a multi-control building opening, as well as 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 command is carried out non-wired (see figure 1a ), for example by wireless 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 arranged in the electronics control 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 motor wired electronic control, called wired electronic motor, power cables also serve as control. This type of device, as represented in figure 1b generally comprises four wires: a wire 20 for the neutral, a wire 21 for the earth, 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, one can use a wired command of another type (see figure 1c ), in which the control electronics 26 remains permanently powered, but in which the power cables (wire 20 for the neutral and phase 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 pushbutton 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.

Moreover, certain uses require that all the controls are centralized on various control devices of the very low voltage type, such as for example organs for telethesis or home automation 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.

It is also known from the document EP 1 274 199 , a device for either controlling the motor via a non-wired control, or to control the motor via a wired control.

Precisely, this device works either in a normal mode or in a special mode.

In the normal mode, only the non-wired control is activated, the receiving module of the wired control not being able to transmit the command to the control unit.

When switching to the special mode, the two types of control, wired or wireless, can be transmitted to the control unit, but it only takes into account the command transmitted by non-wired channel.

In both modes, there is inhibition, direct or indirect, of one or the other of the control modules. In the normal mode, the wired control module is directly inhibited and can not transmit control to the control unit. In the special mode, the wireless control module is indirectly inhibited, the possible command received by the control unit from this module not being taken into account.

This inhibition, direct or indirect, is not desirable in a configuration in which it is desired that the user can use either of the two types of command.

The object of the invention is therefore to provide a solution to the aforementioned problems among other problems, by proposing a motorized system for concealment or closure of a multi-control building opening and a corresponding modular control device. .

The invention thus relates, according to a first aspect, to a control device for a motorized system for occultation or closure of a building opening, such as a roller shutter, a window or a bay window, comprising an engine two directions of rotation.

The device comprises an electronic control unit adapted to receive an input actuating command of the motor and to control it in one or 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 understand a microcontroller.

The control module is able to interpret the actuation command to control the motor, and is electrically powered by the power supply module.

The electronic control unit comprises at least two modules for receiving the actuation command.

Each of these modules is permanently able to transmit this operation command to the control module.

The control module is also able to interpret this actuation command to control the motor in either direction of rotation, regardless of the receiving module that transmits the actuation command received.

Thus, the device of the invention is flexible and can control a motorized system concealment or closure of building in many ways, so that the device can be used in an installation regardless of the constraints of the environment of use.

In addition, the actuation modules are always active, without the need to enter a special operating mode.

In a first embodiment, at least one of the receiving modules of the actuation command, is a module for receiving this command by non-wire way.

In a second variant embodiment, possibly in combination with the first, at least one of the receiving modules of the actuation command, is a module for receiving this command by wire way.

In this case, the receiving module of the actuation command comprises at least one input, this input being electrically powered by the power supply module.

Preferably, this receiving module of the wired control comprises a single input. This entry includes two lines of control, and is activatable 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.

When several reception modules are active, if the electronic control unit receives several actuation commands via the various reception modules, the control module interprets the commands in the order of arrival.

The invention also relates, according to 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.

• figure 2 : représente schématiquement un exemple de dispositif de commande de l'invention.

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:

• Figures 1a, 1b, 1c : schematically represent examples of control device according to the state of the art,
• figure 2 : schematically represents an example of a control device of the invention.

In the embodiment shown in figure 2 , the device therefore comprises an electronic control unit 2, which may take the form of an electronic card, or include such an electronic card, on which are implemented the various functions performed 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 shutter, the rotation of the motor 1 in a first direction causes the deployment of the deck, so closing the shutter, and the rotation of the motor 1 in the second direction of rotation causes the folding of the deck, so 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 also comprises a control logic unit or control module 3.

It is preferable to use a control module 3 consisting of, or comprising a microcontroller.

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 control unit 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 receiving the actuation command, the electronic control unit 2 integrates at least two receiving modules.

In the example shown in figure 2 , the electronic control unit 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 receiving 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 figure 2 the wired reception module 6 comprises a single input 7 fed by the power supply module 4, preferably of the very low voltage type (TBT).

This input 7 is activatable 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 pushbutton 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 modes of operation. , such as end of stroke adjustment mode, sensitivity adjustment mode, reset of motor 1, etc ...

The third module 8 for receiving the actuation command is also a wired reception module.

In the example shown in figure 2 , This wired reception module 8 comprises two inputs 9 and 10 powered by the power supply module 4, preferably 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 also comprises a clean control line 10a and the control line 11 common to the two inputs 9 and 10.

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 clean 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 pushbutton 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 order Actuation is also a wired reception module.

In the example shown in figure 2 , This wired reception module 16 comprises three inputs, all referenced by the same reference 17 for the sake of clarity, supplied by the power supply module 4, preferably of very low voltage type (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 group of inputs 17 comprises a clean command line 17c and the command 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 30.

As explained above, the device of the invention comprises several modules 5, 6, 8, 16 for receiving the actuation command.

Thus, the device of the invention always has at least two receiving modules of the actuation command.

The device is therefore 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.

The control module 3 then interprets the commands in the order of arrival.

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 FIG. figure 2 , depending on the needs.
