The command order receiving module 27 can also allow the reception of command orders sent by wired means.
The control means of the electromechanical actuator 11 comprise hardware and/or software means.
As one non-limiting example, the hardware means may comprise at least one microcontroller.
The electromechanical actuator 11 belonging to the home-automation facility of
The electromechanical actuator 11 is supplied with electricity using at least one battery 24, able to be recharged by at least one photovoltaic cell 25, as illustrated in
The electromechanical actuator 11 makes it possible to move the screen 2 of the concealing device 3.
Here, the electromechanical actuator 11 comprises a power supply cable 18 making it possible to supply electricity from the battery or batteries 24.
A case 17 of the electromechanical actuator 11 is preferably cylindrical.
In one embodiment, the case 17 is made from a metal material. The material of the electromechanical actuator is in no way limiting and may be different, and in particular made from plastic.
The electromechanical actuator 11 also comprises a reducing gear device 19 and an output shaft 20.
The electromechanical actuator 11 may also comprise an end-of-travel and/or obstacle detection device, which may be mechanical or electronic.

Here, the case 17 of the electromechanical actuator 11 is fastened to a support 23, in particular a flange, of the box 9 of the concealing device 3 using the closing off element 21 forming a torque pin, in particular a closing off and torque-reacting head. In such a case where the closing off element 21 forms a torque pin, the closing off element 21 is also called a fixed point of the electromechanical actuator 11.
Here, and as illustrated in
In another embodiment, the electronic control unit 15 is positioned outside the casing 17 of the electromechanical actuator 11, and in particular, mounted on the support 23 or in the closing off element 21.
We will now describe, in reference to
The motorized drive device 5 comprises an autonomous power supply device 26. The electromechanical actuator 11 is electrically connected to the autonomous power supply device 26.
The autonomous power supply device 26 comprises the battery or batteries 24 and the photovoltaic cell or photovoltaic cells 25.
Here, each battery 24 is positioned inside the box 9 of the concealing device 3.
In the following description, the expression “the battery 24” is used to designate one or more batteries depending on the configuration of the autonomous power supply device 26. Likewise, the expression “the photovoltaic cell 25” is used to designate one or more photovoltaic cells depending on the configuration of the autonomous power supply device 26.
Here and as illustrated in
Alternatively, not shown, the photovoltaic cell 25 is electrically connected to the battery 24. Additionally, the battery 24 is electrically connected to the electronic control unit 15.
Here, the battery 24 is of the rechargeable type and supplies electricity to the electromechanical actuator 11. Additionally, the battery 24 is supplied with electricity by the photovoltaic cell 25.
Thus, the recharging of the battery 24 is done by solar energy, using the photovoltaic cell 25.
In this way, the battery 24 can be recharged without having to disassemble part of the box 9 of the concealing device 3.
Advantageously, the motorized drive device 5, and in particular the photovoltaic cell 25, comprises charging elements configured to charge the battery 24 from the solar energy recovered by the photovoltaic cell 25.
Thus, the charging elements configured to charge the battery 24 from the solar energy make it possible to convert the solar energy recovered by the photovoltaic cell 25 into electricity.
In one embodiment, the autonomous power supply device 26 comprises a plurality of photovoltaic cells 25 making up a photovoltaic panel.
In one embodiment, the electricity supply of the electromechanical actuator 11 by the battery 24 can replace a power supply of the electromechanical actuator 11 with an electricity supply grid.
Thus, the electricity supply of the electromechanical actuator 11 by the battery 24 makes it possible to do away with a connection to the electricity supply grid.
In another embodiment, the electricity supply of the electromechanical actuator 11 is done on the one hand by an electricity supply grid, and on the other hand by the battery 24.
Thus, the electricity supply of the electromechanical actuator 11 by the battery 24 in particular makes it possible to make up for a cutoff of the electricity supply of the electromechanical actuator 11 with an electricity supply grid.
In this case, the electromechanical actuator 11 is supplied with electricity, on the one hand by a power supply cable connected to the electricity supply grid, and on the other hand by the battery 24.
Furthermore, the electricity supply of the electromechanical actuator 11 by an electricity supply grid makes it possible to recharge the battery 24, in particular when the battery 24 is not sufficiently recharged by the photovoltaic cell 25.
The electronic control unit 15 is configured to detect supply and cutoff periods of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, only via elements 28 measuring a quantity related to the electricity supply of the electromechanical actuator 11 by this photovoltaic cell 25.
An electricity supply period of the electromechanical actuator 11 from the photovoltaic cell 25 corresponds to the presence of the electrical connection connecting the photovoltaic cell 25 to the electromechanical actuator 11.
An electricity cutoff period of the electromechanical actuator 11 from the photovoltaic cell 25 corresponds to the absence of the electrical connection connecting the photovoltaic cell 25 to the electromechanical actuator 11. The absence of electrical connection connecting the photovoltaic cell 25 to the electromechanical actuator 11 may be due to the removal of the photovoltaic cell 25 relative to the autonomous power supply device 26, the cutoff of the electrical connection between the photovoltaic cell 25 and the electromechanical actuator 11, or the loss of electrical connection between the photovoltaic cell 25 and the electromechanical actuator 11.
Thus, the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 make it possible to detect power supply and cutoff periods of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, so as to use the photovoltaic cell 25, and in particular the electricity supply delivered by the latter to the electromechanical actuator 11, to wake up the electronic control unit 15 or to place the electronic control unit 15 in a standby mode.
In this way, when the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 detect the cutoff of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, the inputs and outputs of the electronic control unit 15, in particular of a microcontroller, are examined at a predetermined frequency lower than that used when the measuring elements 28 detect the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, or even not examined, so as to reduce the electricity consumption by the electronic control device 15 and avoid the discharge of the battery 24.
When the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 detect the cutoff of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, the electronic control unit 15 enters a standby mode, so as to reduce the electricity consumption by the electronic control device 15 and avoid the discharge of the battery 24.
The detection of the electricity cutoff of the electromechanical actuator 11 from the photovoltaic cell 25 by the measuring elements 28 makes it possible to diagnose a defect related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25, and in particular, to signal this defect, through a visual and/or audio signal.
When the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 detect the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, the motorized drive device 5 is able to be controlled.
Here, the electricity supply and cutoff periods of the electromechanical actuator 11 are detected using a direct electrical connection between the measuring elements 28 and the photovoltaic cell 25, and in particular, without the quantity measured by the measuring elements 28 traversing other elements making up the autonomous electricity supply device 26, for example the battery 24.
The detection of an electricity supply or cutoff of the electromechanical actuator 11 from the photovoltaic cell 25 is implemented by the measurement, through measuring elements 28, of a quantity related to the supply of electricity delivered by the photovoltaic cell 25.
The quantity related to the electricity supply delivered by the photovoltaic cell 25 may in particular be a voltage, a current or an impedance.
The value of the quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 is proportional to the light power captured by the photovoltaic cell 25, in other words, the value of this quantity supplying electricity to the electromechanical actuator 11 depends on the light intensity of the solar energy captured by the photovoltaic cell 25.
Here, the measuring elements 28 are an integral part of the electronic control unit 15.
As non-limiting examples, the measuring elements 28 may comprise either a voltage divider, a comparator and a microcontroller, one of the inputs of which is provided with an analog-digital converter, if the measured quantity is a voltage, or a shunt resistance and a microcontroller, one of the inputs of which is provided with an analog-digital converter, if the measured quantity is a current.
The electronic control unit 15 is also configured to reset at least part of the data stored by the electronic control unit 15, after the simulation of a sequence of supply and cutoff periods of the electricity supply of the electromechanical actuator 11, where the supply and cutoff periods of the electricity supply are detected through measuring elements 28.
Thus, the electronic control unit 15 can be reset, at least partially, by executing a series of electricity supply and cutoff periods of the electromechanical actuator 11, where the electricity supply and cutoff periods of the electrochemical actuator 11 are determined through measuring elements 28 measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25.
In this way, at least part of the data stored by the electronic control unit 15 is reset, following the detection by the measuring elements 28 of the sequence of periods respectively corresponding to the presence or absence of the electrical connection connecting the photovoltaic cell 25 to the electromechanical actuator 11.
The data stored by the electronic control unit 15 being able to be reset can be the end-of-travel positions of the screen 2, the obstacle detection threshold(s), the control point(s) 12, 13, 14 paired with the electromechanical actuator 11.
In a first embodiment, the sequence of supply and cutoff periods of the electricity supply of the electromechanical actuator 11 is simulated by the connection and disconnection of a first electrical connector 29 connected to the photovoltaic cell 25 cooperating with a second electric connector 30 connected to the electronic control unit 15.
Thus, an electricity supply period of the electromechanical actuator 11 by the photovoltaic cell 25 is carried out by the electrical connection of the first electrical connector 29 connected to the said at least one photovoltaic cell 25 with the second electrical connector 30 connected to the electronic control unit 15. Additionally, an electricity cutoff period of the electromechanical actuator 11 from the photovoltaic cell 25 is carried out by the electrical disconnection of the first electrical connector 29 connected to the said at least one photovoltaic cell 25 with respect to the second electrical connector 30 connected to the electronic control unit 15.
In this way, the measuring elements 28 measure a quantity related to the electricity supply delivered by the photovoltaic cell 25. When the first electrical connector 29 connected to the said at least one photovoltaic cell 25 is connected on the second electrical connector 30 connected to the electronic control unit 15, the value of the measured quantity is above a threshold value, which means that the photovoltaic cell 25 is capturing rays of light. When the first electrical connector 29 connected to the said at least one photovoltaic cell 25 is disconnected from the second electrical connector 30 connected to the electronic control unit 15, the value of the measured quantity is zero and therefore below a threshold value, which means that the photovoltaic cell 25 is not capturing rays of light.
Here and as illustrated in
In such an embodiment, the first and second electrical connectors 29, 30 respectively connected to the said at least one photovoltaic cell 25 and to the electronic control unit 15 are accessible, in particular, by disassembling part of the box 9 of the concealing device 3.
In a second embodiment, the sequence of electricity supply and cutoff periods of the electromechanical actuator 11 is simulated using an outside electricity supply source 31. The outside electricity supply source 31 is electrically connected to the electromechanical actuator 11, replacing the photovoltaic cell 25.
Thus, an electricity supply period of the electromechanical actuator 11 by the outside electricity supply source 31 is carried out either by the electrical connection of the second electrical connector 30 connected to the electronic control unit 15 with a third electrical connector 32 connected to the outside electricity supply source 31, or by the closure of a switch of the outside electricity supply source 31. Additionally, an electricity cutoff period of the electromechanical actuator 11 from the outside electricity supply source 31 is carried out either by the electrical disconnection of the second electrical connector 30 connected to the electronic control unit 15 with respect to the third electrical connector 32 connected to the outside electricity supply source 31, or by the opening of the switch of the outside electricity supply source 31.
In this way, the measuring elements 28 measure a quantity related to the electricity supply delivered by the outside electricity supply source 31. When the second electrical connector 30 connected to the electronic control unit 15 is connected on the third electrical connector 32 connected to the outside electricity supply source 31, or when the switch of the outside electricity supply source 31 is closed, the value of the measured quantity is above a threshold value. When the second electrical connector 30 connected to the electronic control unit 15 is disconnected from the third electrical connector 32 connected to the outside electricity supply source 31, or when the switch of the outside electricity supply source 31 is open, the value of the measured quantity is zero and therefore below a threshold value.
Here and as illustrated in
Advantageously, the simulation of the sequence of electricity supply and cutoff periods of the electromechanical actuator 11 using the outside electricity supply source 31 is carried out when the photovoltaic cell 25 is faulty or when the photovoltaic cell 25 is not installed in the motorized drive device 5, in particular during an after-sales service operation or during the assembly of the motorized drive device 5.
In such an embodiment, the first, second and third electrical connectors 29, 30, 32 respectively connected to the said at least one photovoltaic cell 25, to the electronic control unit 15 and the outside electricity supply source 31 are accessible, in particular, by disassembling part of the box 9 of the concealing device 3.
Here, the outside electricity supply source 31 can be a transformer electrically connected to an electric grid, so as to convert an alternating voltage into a direct voltage.
The alternating voltage of the electric grid or sector voltage has, for example, a value of 230 VRMS (peak value of 325 V) for the French electric grid. Of course, the sector voltage may have different values, depending on the electric grid of the country in which the home-automation facility is installed.
The direct supply voltage of the electromechanical actuator 11, obtained at the output of the transformer, may for example be 12 V.
Alternatively, an electricity supply period of the electromechanical actuator 11 by the outside electricity supply source 31 is carried out by the electrical connection of an electric jack 34 connected to the outside electricity supply source 34 with an electric jack, not shown, connected to the electric grid, as well as the electrical connection of the second electrical connector 30 connected to the electronic control unit 15 with the third electrical connector 32 connected to the outside electricity supply source 31. Additionally, an electricity cutoff period of the electromechanical actuator 11 from the outside electricity supply source 31 is carried out by the electrical disconnection of the electric jack 34 connected to the outside electricity supply source 31 relative to the electric jack connected to the electric grid.
Here and as illustrated in
In a third embodiment, the sequence of power supply and cutoff periods of the electricity supply of the electromechanical actuator 11 is simulated by removing a cover element 33 from the photovoltaic cell 25 and positioning the cover element 33 on the photovoltaic cell 25.
Thus, an electricity supply period of the electromechanical actuator 11 by the photovoltaic cell 25 is carried out by the removal of the cover element 33 placed on the photovoltaic cell 25. Additionally, an electricity cutoff period of the electromechanical actuator 11 from the photovoltaic cell 25 is carried out by the positioning of the cover element 33 on the photovoltaic cell 25.
In this way, the measuring elements 28 measure a quantity related to the electricity supply delivered by the photovoltaic cell 25. When the cover element 33 is removed with respect to the photovoltaic cell 25, the value of the measured quantity is above a threshold value, which means that the photovoltaic cell 25 is capturing rays of light. When the cover element 33 is placed on the photovoltaic cell 25, the value of the measured quantity is below a threshold value, which means that the photovoltaic cell 25 is capturing no or insufficient rays of light. In such an embodiment, the first and second electrical connectors 29, 30 respectively connected to the said at least one photovoltaic cell 25 and to the electronic control unit 15 may not be accessible.
By way of non-limiting example, the first, second and third electrical connectors 29, 30, 32 respectively connected to the said at least one photovoltaic cell 25, to the electronic control unit 15 and to the outside electricity supply source 31 are arranged at the support 23, and in particular, inside the box 9 of the concealing device 3, following the assembly of the motorized drive device 5 in the concealing device 3.
Advantageously, the electronic control unit 15 comprises the module 27 for receiving command orders wirelessly.
In practice, the wireless command order receiving module 27 is inhibited, following the detection by the electronic control unit 15 of the electricity cutoff of the electromechanical actuator 11 from the photovoltaic cell 25.
Thus, once the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 detect the cutoff of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25, the electronic control unit 15 enters a standby mode, called deep, so as to inhibit the wireless command order receiving module 27.
In this way, the transition to a standby mode, called deep, following the detection of the cutoff of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25 by the measuring elements 28 makes it possible to reduce the electricity consumption by the electronic control device 15 and avoid the discharge of the battery 24.
Advantageously, the wireless command order receiving module 27 is woken up at a predetermined frequency, so as to detect command orders sent, in particular by a command order transmitter that may for example be the remote control 14, to the electronic control unit 15.
The waking of the wireless command order receiving module 27 at a predetermined frequency is carried out, preferably, in a standby mode, called active, from the electronic control unit 15, so as to temporarily inhibit the wireless command order receiving module 27.
The standby mode, so-called active, of the electronic control unit 15 is carried out, preferably, when the elements 28 for measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 detect the supply of electricity of the electromechanical actuator 11 from the photovoltaic cell 25, and when the wireless command order receiving module 27 has not received any command order, after a predetermined length of time has elapsed.
In one embodiment, the predetermined frequency for waking up the wireless command order receiving module 27 depends on the illumination power determined by measuring elements 28 measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25.
Thus, the adaptation of the predetermined frequency for waking up the wireless command order receiving module 27 as a function of the illumination power determined by measuring elements 28 makes it possible to reduce the electricity consumption by the electronic control unit 15 and to limit the discharge of the battery 24.
In this way, the wake-up frequency of the wireless command order receiving module 27 is extended at night and reduced during the day, so as to reduce the electricity consumption by the electronic control unit 15 at night and guarantee reactive operation of the motorized drive device 5 during the day.
Advantageously, the predetermined frequency for waking up the wireless command order receiving module 27 can assume a plurality of values defined as a function of illumination power threshold values.
In one example embodiment, the wake-up frequency of the wireless command order receiving module 27 may be about 150 milliseconds when the illumination power determined via the measuring elements 28 is less than 10 W/m2, 70 milliseconds when the illumination power determined via the measuring elements 28 is comprised between 10 W/m2 and 200 W/m2, and 20 milliseconds when the illumination power determined via the measuring elements 28 is greater than 200 W/m2.
In another embodiment, the predetermined frequency for waking up the wireless command order receiving module 27 depends on the charge level of the battery 24.
Thus, the adaptation of the predetermined frequency for waking up the wireless command order receiving module 27 as a function of the charge level of the battery 24 makes it possible to reduce the electricity consumption by the electronic control unit 15 and to avoid the discharge of the battery 24.
In this way, the reaction time of the motorized drive device 5 after the transmission of the command order, in particular from the remote control 14, allows the user to deduce the charge level of the battery 24 therefrom, since the predetermined wake-up frequency of the wireless command order receiving module 27 is longer or shorter, as a function of the charge level of the battery 24.
In another embodiment, the predetermined frequency for waking up the wireless command order receiving module 27 depends, on the one hand, on the illumination power determined by measuring elements 28 measuring a quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25 and, on the other hand, on the charge level of the battery 24.
In one example embodiment, the wake-up frequency of the wireless command order receiving module 27 may be about 150 milliseconds when the illumination power determined via the measuring elements 28 is less than 10 W/m2 and the charge level of the battery 24 is greater than or equal to 50%, 300 milliseconds when the illumination power determined via the measuring elements 28 is less than 10 W/m2 and the charge level of the battery 24 is less than 50%.
We will now describe a method for controlling the operation of the motorized drive device 5 according to one embodiment of the invention.
The control method comprises a step for detecting supply and cutoff periods of the electricity supply of the electromechanical actuator 11 from the photovoltaic cell 25.
This detection step is carried out only using elements 28 for measuring a quantity related to the power supply of the electromechanical actuator 11 by the said at least one photovoltaic cell 25.
Following the detection of a period for supplying electricity for the electromechanical actuator 11 from the photovoltaic cell 25, the electronic control unit 15 enters a standby mode, so-called active, during which the inputs and outputs of the electronic control unit 15, in particular a microcontroller, are examined at a predetermined frequency. Additionally, in particular, the wireless command order receiving module 27 is woken up at a predetermined frequency, so as to receive a command order sent by a command order transmitter, which may for example be the remote control 14.
Additionally, following the detection of a period for cutting off electricity for the electromechanical actuator 11 from the photovoltaic cell 25, the electronic control unit 15 enters a standby mode, so-called deep, during which the inputs and outputs of the electronic control unit 15, in particular a microcontroller, are examined at a predetermined frequency that is less than that of the standby mode, so-called active, carried out following the detection of a period for supplying electricity for the electromechanical actuator 11 from the photovoltaic cell 25. In particular, the wireless command order receiving module 27 is inhibited, so as to reduce the electricity consumption by the electronic control unit 15 and to avoid the discharge of the battery 24.
Preferably, the predetermined frequency for the examination of the inputs and outputs of the electronic control unit 15, in particular a microcontroller, and, in particular, standby of the wireless command order receiving module 27 is reduced, when the measuring elements 28 measure a zero value or a value below a threshold value of the quantity related to the electricity supply of the electromechanical actuator 11 by the photovoltaic cell 25.
The control method also comprises a step for simulating a sequence of supply and cutoff periods of the electricity supply of the electromechanical actuator 11, where the supply and cutoff periods of the electricity supply are detected through measuring elements 28.
This simulation step can be carried out by the electrical connection and disconnection of the first electrical connector 29 connected to the said at least one photovoltaic cell 25 cooperating with the second electrical connector 30 connected to the electronic control unit 15, using the outside electricity supply source 31 electrically connected to the electromechanical actuator 11 by replacing the photovoltaic cell 25, or by the positioning or removal of the cover element 33 on the photovoltaic cell 25.
The control method comprises a step for resetting at least part of the data stored by the electronic control unit 15, after the simulation step is carried out.
In one example embodiment, the sequence of supply and cutoff periods of the electricity supply of the electromechanical actuator 11 comprises a first cutoff period of the electricity supply during a predetermined time period, which may be approximately two seconds, an electricity supply period for a predetermined time period, which may be approximately seven seconds, and a second electricity cutoff period for a predetermined time period, which may be approximately two seconds.
After the simulation step is carried out, at least part of the data stored by the electronic control unit 15 can be reset, in particular once the predetermined time period of the second cutoff period of the electricity supply has elapsed.
Owing to the present invention, the elements for measuring a quantity related to the electricity supply of the electromechanical actuator by the photovoltaic cell make it possible to detect power supply and cutoff periods of the electricity supply of the electromechanical actuator from the photovoltaic cell, so as to use the photovoltaic cell, and in particular the electricity supply delivered by the latter to the electromechanical actuator, to wake up the electronic control unit or to place the electronic control unit in a standby mode.
The present invention also makes it possible to reset, at least partially, the data stored by the electronic control unit, by executing a series of electricity supply and cutoff periods of the electromechanical actuator, where the electricity supply and cutoff periods of the electrochemical actuator are determined through measuring elements measuring a quantity related to the electricity supply of the electromechanical actuator by the photovoltaic cell.
Many changes can be made to the example embodiments previously described without going beyond the scope of the invention defined by the claims.
In particular, the battery may be a single battery or a group of batteries connected using an electrical insulator.
Furthermore, the considered embodiments and alternatives may be combined to generate new embodiments of the invention, without going beyond the scope of the invention defined by the claims.
