Description

The present invention relates to the field of remote control and/or control devices using radiofrequency signals. The invention relates more particularly to a remote control device, a home automation equipment and an associated home automation system.

The invention can find its application in the field of home automation and/or building automation for buildings for residential, commercial or industrial use. It can be used to command and/or control one or more electrical equipment also called “electrical loads”. The electrical load may be intended, for example, for thermal, visual or light comfort, solar protection, closure and/or security of a building or its surroundings. The electrical load can be a lighting element such as a halogen or light-emitting diode bulb, an electric pump, a heater, an air conditioner, a ventilation device, an alarm siren. The electrical load can also be an electromechanical actuator and in particular a high torque electromechanical actuator consuming a high amplitude current. The actuator may be intended to move a mobile screen such as a rolling shutter, an awning, a Venetian blind, a door, a gate, a grille, a window or a hatch.

A remote control device comprises a radio frequency receiving module arranged to receive radio frequency instruction signals from a remote device. According to a variant embodiment, the radiofrequency module is a transmission and/or reception module arranged to exchange radiofrequency signals with the remote device.

According to one embodiment, the radiofrequency module is electrically connected to a radiofrequency antenna in order to increase its radiofrequency range. In order to conceal the antenna connected to the radiofrequency module, it is known, for example from the patent application FR-A1-3061340 , to use at least one electrical conductor of the power supply network as a receiving and/or transmitting antenna of indeterminate length for the radio frequency signals. The electrical conductor used as a radiofrequency antenna therefore conveys the alternating power supply signal as well as the radiofrequency control signal picked up and/or to be radiated. In order to separate the control signal, the remote control device includes a filter circuit. The filter circuit includes at least three ports. Signal overlay conveyed by the electrical conductor enters through a first port of the filter circuit. The filter circuit then separates the power signal from the control signal. The power signal is directed to a port of the filter to power the remote control device and the electrical load connected thereto. The control signal is directed to another port of the filter to be processed by the radiofrequency module.

A problem arises when the remote control device is used to control a high power electrical load. Indeed, the filter circuit comprises one or more inductors and when an inductor is traversed by an alternating current of high amplitude, a strong rise in the temperature of the inductor is observed. By way of example, temperatures of more than 150° C. can be observed on the filter circuit when a current of about ten amperes passes through it. The sharp rise in temperature within the inductance can lead to the destruction of the filtering circuit and its support, or even cause a fire to start.

Another problem arises when at least one inductance of the filter circuit is formed on the printed circuit board (also called PCB for " Printed Circuit Board " according to the English terminology) on which the filter circuit is located. The inductor can, for example, be an inductor printed on the printed circuit board of the control device. When the filter circuit is intended to be crossed by a strong current, the width of the tracks used to produce the printed inductance is increased in order to withstand the high amplitude of the current. This has the consequence of creating a large bulk on the printed circuit board, especially when the filter circuit comprises several printed impedances. The location occupied by the printed inductors increases the size of the printed circuit board and therefore its manufacturing cost. Additionally, it increases the size of the slot needed to house the circuit board. This situation becomes problematic when the remote control device is intended, for example, for a tubular electromechanical actuator of a mobile screen. Indeed, the printed circuit board on which the remote control device is located must be able to fit into the reduced housing formed by the winding tube of the actuator. The same problem is encountered when the remote control device is installed in a micromodule intended to be housed in a recessed box, for example, between the bottom of said box and a wall switch.

The large width of the track(s) of the inductor intended to withstand a high amplitude current also poses a problem when the frequency of the carrier of the control signals is high, for example, of the order of 2.4 GHz. Indeed, the dimensions of an inductance formed by printed turns is inversely proportional to the working frequency. By way of example, for a carrier frequency of the order of 2.4 GHz, a printed inductor has an outside diameter of 4 to 5 mm. Moreover, in order to support a high power, the tracks of the printed inductor have a width of at least 3mm. Under these conditions, it becomes difficult to produce an inductance in the form of printed turns, that is to say by winding a printed circuit track in a square or round spiral.

An object of the invention is in particular to correct all or part of the aforementioned drawbacks by proposing a remote control device using at least part of an electrical conductor of the electrical power supply network, or an electrical conductor of a mains cable electrically connected to said power supply network, as an antenna and capable of controlling a high power electrical load without overheating problem.

To this end, the subject of the invention is a remote control device according to claims 1 to 8.

Another object of the invention is equipment according to claims 9 and 10.

The invention also relates to a home automation system according to claim 11.

With reference to the figure 1 , the remote control device 1 is configured to be electrically connected in series between an electrical power supply network 2 (also called mains) and at least one electrical load 3. The remote control device is arranged to cooperate with a remote device 4.

The remote device 4 can be, for example, a remote control, a smart phone (or " smartphone " in English terminology), a tablet, a multiservice box (or " box " in English terminology), a computer connected to a communication network or any other equivalent device capable of transmitting at least one control instruction. It can be a radiofrequency transmitter, mobile or fixed.

The remote device is either of the unidirectional type, that is to say purely transmitter, or of the bidirectional type, that is to say transmitter and receiver, or of the mixed type. For this, it comprises at least one radio frequency module (not shown) configured to transmit and/or receive radio frequency signals representative of control commands on at least one frequency and at least one communication protocol intended for the remote control device 1 to control at least one electrical load 3.

The electric power supply network 2 is, for example, a single-phase electric network, a three-phase electric network or more generally a polyphase electric network. By way of example, a single-phase electrical network can deliver an effective voltage with an amplitude equal to approximately 230V or 120V, with a frequency of approximately 50 Hz or 60Hz. A three-phase electrical network can deliver an effective voltage with an amplitude equal to about 380V or 230 V between each of the phase conductors and an effective voltage with an amplitude equal to about 120V or 230 V between each phase conductor and the neutral conductor.

The connection of the remote control device 1 to the electrical power supply network is made via at least two electrical conductors of the power supply network. In the embodiment illustrated in the figure 1 , the remote control device 1 is electrically connected to two electrical conductors, a neutral conductor and a phase conductor.

According to a variant embodiment, the electrical connection of the remote control device 1 to the electrical power supply network is made via at least two or three phase conductors. According to another embodiment, the electrical connection also comprises a protective conductor connected to ground.

According to a variant embodiment, the electrical connection of the remote control device 1 to the electrical power supply network is made via a mains cable (not shown). The mains cable comprising at least two electrical conductors.

There figure 2 represents an exemplary embodiment of a remote control device according to the invention. The remote control device comprises at least one filter module 11, one power supply module 12, one radio frequency module 13 and one control module 14.

The remote control device is configured to be supplied with electrical energy by the electrical power supply network 2. To do this, according to one embodiment, the remote control device 1 comprises at least two power supply terminals 15, 16. According to another embodiment, the remote control device 1 comprises as many supply terminals as electrical conductors necessary for the electrical connection of the device 1 to the supply network 2. Each of the supply terminals is intended to be electrically connected to one end of an electrical conductor of the electrical power supply network 2 or of a mains cable electrically connected to the electrical power supply network 2.

According to one embodiment, the remote control device 1 comprises at least one output terminal 17. The output terminal is configured to electrically connect an electrical load.

According to one embodiment, a supply terminal of the remote control device 1 also performs an output terminal function. For example, an electrical load can be connected between an output terminal and a supply terminal intended to be electrically connected to a neutral conductor of the supply network 2.

According to one embodiment, the remote control device 1 is connected to a radiofrequency antenna in order to increase the radiofrequency range of its radiofrequency module 13.

According to one embodiment, at least one first supply conductor of the electric power supply network 2 behaves like a radio frequency antenna. The antenna is formed by all or part of the first supply conductor of the electrical power supply network 2. When the remote control device 1 is connected to the electrical power supply network via a mains cable, a first conductor of the mains cable behaves like an antenna. According to one embodiment, the antenna extends over the first electrical conductor of the power supply network 2 to which the first electrical conductor of the mains cable is electrically connected. This scenario occurs when the length of the mains cable is less than the length of the antenna.

According to a preferred embodiment, all or part of the electrical neutral conductor forms the antenna. In this embodiment the first supply terminal of the remote control device is configured to be connected to a neutral conductor of the supply network 2. The neutral conductor is a conductor of the mains cable and/or of the supply network 2 for electrical energy.

The radiofrequency signals propagating on the electrical conductor constituting the antenna therefore comprise at least two radiofrequency components. The radiofrequency signals comprise a first so-called "low frequency" component (typically at a frequency of 50 Hz or 60 Hz) corresponding to the electrical supply signals and a so-called "high frequency" radiofrequency component comprising at least radioelectric signals representative of control commands captured by the first electrical conductor and propagating on the latter. The so-called high-frequency component also comprises other radiofrequency signals picked up by the first electrical conductor and/or conducted by the latter via the electrical power supply network.

The remote control device 1 comprises a radiofrequency filter circuit 11 configured to filter the radiofrequency signals propagating on the first supply conductor of the supply network 2. The filter circuit 11, also called a radiofrequency coupler, comprises several terminals entry/exit. In the embodiment illustrated in the figure 1 , the filter circuit comprises three input/output terminals 111, 112, 113. A first terminal 111 is electrically connected to the first power supply terminal 15. A second terminal 112 is electrically connected to a terminal of the power supply module 12. A third terminal 113 is electrically connected to a radiofrequency input/output terminal 133 of the radiofrequency module 13.

The radio frequency filter circuit 11 is configured to separate different components of the radio frequency signals and direct each separated component to a terminal of the filter circuit. In the example shown in the figure 1 , the radio frequency filter circuit is arranged to separate the radio frequency signals carried by the first conductor at a predetermined frequency and direct them to the third terminal 113 of the filter circuit 11. The predetermined frequency corresponds to the frequency of the carrier used to transmit the radiofrequency signals emitted by the remote device and picked up by the radiofrequency module 13 or the antenna electrically connected to the latter 13.

The filter circuit 11 is also configured to limit the propagation of radiofrequency signals between the first and the second terminal 112 of the circuit of filtering. The signals whose propagation is stopped correspond to signals whose frequency is different from that of the supply signals.

As stated above, the radio frequency signals entering the filter circuit 11 comprise the superposition of at least one power supply signal and a radio frequency signal representative of control commands, for example picked up by the first conductor forming an antenna radio frequency. The power supply signal is transmitted through the filter circuit to the power supply module and the radio frequency signal representative of control commands is transmitted through the filter circuit to the radio frequency module 13. The propagation of the other radio frequency signals is stopped or at least limited. According to one embodiment, the radio frequency signals whose propagation is stopped are conducted to a ground of the remote control device 1.

With reference to the picture 3 , the filter circuit 11 may comprise at least one tuning circuit 30 and two decoupling capacitors C1, C2.

THE figures 4 and 5 illustrate exemplary embodiments of such a tuning circuit 30. The tuning circuit comprises at least one inductor (also called coil) and one capacitor electrically connected in a parallel arrangement to form a resonant circuit or dimmer circuit. insulation (also known as a “circuit trap”). The inductance and capacitor of the tuning circuit are sized so that the resonant circuit is tuned to a frequency substantially equal to the frequency of the signals to be separated. It may be the power supply signal or the carrier used for the transmission of radio frequency signals. According to one embodiment, the carrier used for the transmission of radiofrequency signals representative of control commands at a frequency greater than 100 MHz. According to particular embodiments, the frequency of the carrier is equal to approximately 433 MHz, 868 MHz or 2.4 GHz...

According to a first embodiment, illustrated in the figure 4 , the tuning circuit 30 comprises an inductor L21 and a capacitor C21 electrically connected in parallel. The second terminal 32 of the tuning circuit 30 is connected to the inductor L21 at a point located between the two ends of said inductor. In this embodiment, inductance L21 is fictitiously divided into two coupled windings placed in series, the second terminal 32 being connected to the common terminal of these two windings.

There figure 5 shows a second embodiment of the tuning circuit 30 comprising an inductor L22 and two capacitors C22, C23, the inductor being electrically connected in parallel with the two capacitors. The two capacitors C22, C23 are electrically connected in series and the second terminal 32 of the tuning circuit 30 is connected to the common point of these two capacitors.

With reference to the picture 3 , the tuning circuit 30 comprises three terminals referenced 31, 32, 33. A first terminal 31 of the tuning circuit 14 is connected to the first input terminal of the filter circuit 11. The second terminal 32 of the agreement 30 is electrically connected to the third output terminal 113 of the filter circuit 11 via a decoupling capacitor C2. The decoupling capacitor C2 makes it possible to block the propagation of radiofrequency signals with a frequency lower than a predetermined frequency, or cut-off frequency, and to authorize the propagation of signals with a frequency higher than this predetermined frequency. Advantageously, the value of this capacitor C2 is therefore chosen so as to block the propagation of the electric power supply signals called low frequency, that is to say whose frequency is substantially equal to that of the electric power supply network 2 The third terminal 33 of the tuning circuit 30 is electrically connected to the second output terminal 112 of the filter circuit 11.

The tuning circuit 30 forms a voltage collector for the radiofrequency input/output port 133 of the radiofrequency module 13 to which it is connected and must be referenced to the electrical ground GND of the remote control device 1. As stated previously, the circuit filter 11, and therefore the tuning circuit, is connected to the first supply terminal 15 of the remote control device. In order not to produce a short-circuit between the first power supply terminal 15 and the electrical ground GND at low frequencies, the third terminal 33 of the tuning circuit 14 is connected to the electrical ground GND of the remote control device 1 via a decoupling capacitor C1. Advantageously, the decoupling capacitor C1 makes it possible to avoid the propagation of the supply signals to the electrical ground GND. The third terminal 33 of the tuning circuit 30 is connected as close as possible to the electrical ground GND. The distance between the electrical ground connection point and the tuning circuit 30 is less, preferably much less, than a quarter of the wavelength associated with the frequency to which the tuning circuit is tuned. By very inferior, we mean at least, ten times or even a hundred times, inferior.

With reference to the figure 2 , the filter circuit is electrically connected to a radiofrequency input/output terminal 133 of the radiofrequency module 13 via a radiofrequency link 1113.

According to one embodiment, the remote control device 1 comprises an impedance matching circuit (not shown) electrically connected to the radiofrequency input/output terminal 133 of the radiofrequency module 13. The matching circuit is configured to bring back to the level of the radiofrequency input/output terminal 133 of the radiofrequency module 13 a predetermined impedance value. The predetermined impedance value corresponds to a value substantially equal to the value of the input (or output) impedance of the radiofrequency module 13. The value of the input (or output) impedance is, for example , equal to 50 Ohms.

According to one embodiment, the matching circuit is a separate circuit on the radio frequency link 1113.

According to a variant embodiment, the adaptation circuit is integrated into the radio frequency filter circuit 11 . The filtering circuit therefore performs the two functions of filtering and adaptation.

According to one embodiment, the remote control device is installed on a printed circuit board (or PCB for " Printed Circuit Board " according to the English terminology). The printed circuit board can be a single-sided, double-sided, single-layer or multi-layer board. At least one face of the card can be completely or partially metallized in order to form a ground plane.

According to one embodiment, all or part of the inductances of the filter circuit and/or of the tuning circuit and/or of the matching circuit are printed inductances. According to one embodiment, a printed inductance is, for example, produced in the form of turns printed on a metallized face of the printed circuit board.

According to one embodiment, the radiofrequency module 13 is a radiofrequency reception module in order to receive radiofrequency signals representative of control commands from a remote device. According to a variant embodiment, it is a radio frequency transmission and/or reception module in order to exchange radio frequency signals with a remote device 4.

The radiofrequency module 13 comprises at least one radiofrequency input/output terminal 133 configured to receive and/or deliver radiofrequency signals. The radio frequency module 13 includes an output terminal 134 configured to deliver a control signal to the control module 14.

The radiofrequency module 13 comprises various elements known to those skilled in the art and not shown in order to receive and decode radiofrequency signals representative of control commands and possibly to transmit signals representative of information on the input terminal /radiofrequency output 133 of the radiofrequency module. It may be a High Frequency amplifier-demodulator circuit, one or more microcontrollers or processors and/or any other equivalent means programmed in a timely manner.

The radiofrequency module 13 is configured to cooperate with a remote device 4 as described above.

According to one embodiment, the radiofrequency module 13 is connected to a radiofrequency antenna in order to increase its radiofrequency range.

The radiofrequency module 13 is supplied with electrical energy by a power supply module 12. The radiofrequency module is electrically connected to the power supply module 12, for example via at least two power supply terminals 131, 132.

The power supply module 12 is supplied with electrical energy by the electrical power supply network. According to the invention, the power supply module is electrically connected to the first power supply terminal 15 via the filter circuit 11. The power supply module is also connected to the second power supply terminal 16. According to the invention, the power supply module is connected to the second power supply terminal 16 via a mains filter circuit (not shown). The mains filter circuit is, for example, formed by a capacitor and an inductor connected in parallel. The elements of the mains filter circuit are dimensioned in order to filter the radiofrequency interference transmitted by the second conductor of the supply network 2.

The function of the power supply module is to generate the supply voltage(s) necessary for the operation of the various modules and electronic circuits of the remote control device 1 from the electrical energy supplied by the power supply network 2. For this, the power supply module comprises a circuit for transforming the voltage of the power supply network into at least least one voltage capable of supplying the radiofrequency circuit 13. According to one embodiment, the supply circuit transforms the alternating voltage of the power supply network into one or more direct or alternating voltages of amplitude adapted to the supply of electrical energy of the various components of the radiofrequency circuit. It may be, for example, a DC voltage with an amplitude equal to approximately 3V, 5V or 12V. According to one embodiment, when the power supply module delivers several output voltages, all of the output voltages can comprise at least one DC voltage and at least one AC voltage.

At least one output voltage of the power supply module 12 can be intended to supply a control module 14 of the remote control device 1.

The command module is configured to execute the commands corresponding to the instructions transmitted by the remote device 4.

The control module includes several input, output and/or input/output terminals. The control module 14 is in particular configured to control the quantity of electrical signal passing through said control module between at least two terminals as a function of control signals received on at least one control terminal. According to one embodiment, the electrical signal passing through the control module 14 is a power supply signal (current, voltage) arranged to supply the electrical load 3. According to another embodiment,

According to one embodiment, the control module 14 is a switching device configured to authorize the passage of an electrical signal between at least one input terminal and one output terminal in an operating mode (or state) generally called "closed" and interrupt the passage of the signal between the two aforementioned terminals in an operating mode (or state) generally called "open". In this embodiment, control of the amount of signal passing through the control module is in an on/off mode. It may be, for example, an electromechanical or static relay, a triac, a thyristor or any other type of power electronics equipment.

In the exemplary embodiment illustrated in the figure 2 , the control module 14 is a monopolar device. The control module comprises three terminals 141, 142, 143. A first input terminal 141 is electrically connected to the second supply terminal of the remote control device. A second output terminal 142 of the control module 14 is electrically connected to an output terminal 17 of the remote control device 1. A third control terminal 143 is electrically connected to output terminal 134 of radiofrequency module 13.

According to a variant embodiment, the control module is a bipolar switching device or more generally a multipolar device. By way of example, such a switching device makes it possible to switch several phases of the power supply network 2.

According to a variant embodiment, the control module is a dimmer or dimmer configured to gradually adjust the passage of the signal passing through it. For example, the control module increases (or decreases) by a predetermined value the quantity of signal passing between the input and output terminals of the control module. The control module thus makes it possible to vary the power delivered to the electrical load.

According to another embodiment, the control module is a selector making it possible to direct the electrical signal entering the control module towards one or more particular terminals selected from among a plurality of terminals or to stop the passage of the electrical signal.

At least one input terminal 141 of the control module 14 is connected to a power supply terminal 15, 16 of the remote control device 1. The input terminal 141 of the control module is connected to a power supply terminal of the remote control device 1 intended to be connected to a phase conductor of the power supply network 1. According to a preferred embodiment, the input terminal 141 of the control module 14 is connected to a power supply terminal 16 not intended to be connected to the conductor of the supply network 2 providing a radio frequency antenna function. Advantageously, such an electrical connection avoids mismatching of the radiofrequency link 1113 each time the control module 14 changes state.

The electrical connection of the input terminal 141 of the control module to the power supply terminal of the remote control device 1 is made between said power supply terminal and the mains filter circuit.

Thus, when a high intensity current is consumed at one or more output terminals 17 of the remote control device 1, the current consumed does not pass through any of the inductance of the mains filter circuit. Thus no heating is observed in the mains filter circuit. As stated previously, the filter circuit 11 is connected to the first supply terminal 15 of the remote control device 1. Thus, no high current intensity does not cross the inductances of this filter circuit 11 when a high intensity current is consumed at the level of one or more output terminals 17. By high intensity current, we mean a current of intensity greater than 3 A.

According to one embodiment, the remote control device 1 comprises a zero crossing detection circuit of the electrical signal (not shown) electrically connected to a supply terminal of the remote control device. The detection of zero crossing of the electric signal (or “ zero crossing ” according to English terminology) is, for example, performed on at least one phase of the electric power supply network.

According to one embodiment, the electrical signal zero crossing detection circuit is connected to a connection point on an electrical connection between the network filtering circuit and the power supply module.

The function of the zero detection circuit is to detect the passage to zero of the alternation of the electric signal of the power supply network 2 in order to synchronize the changes of state of the control module with this detection. The zero detection circuit makes it possible to trigger the switching of the power at the time of the zero crossing of the electrical signal, which considerably reduces electrical and electromagnetic pollution, for example, when the switched load is resistive. Advantageously, the detection of zero crossings of the voltage of the power supply network makes it possible to avoid the formation of overvoltage peaks during the change of state of the control module. The detection of zero crossings also makes it possible to avoid rapid variations in current, sources of electromagnetic disturbance, during the change of state of the control module 14. By way of example, a change of state of the control module carried out during the zero crossing makes it possible to prevent the formation of an electric arc in a relay during switching of the control circuit in order to supply a load of the bulb type with light-emitting diodes (or LED for " Light Emitting Diode " according to Anglo-Saxon terminology) presenting a high amplitude inrush current.

Another object of the invention is home automation equipment intended for example for thermal, visual or light comfort, solar protection, closure and/or security of a building or its surroundings. The home automation equipment is intended to be electrically connected to the electrical power supply network and comprises a remote control device 1 as described above and an electrical load. According to a first embodiment, the home automation equipment is intended to be connected to an electrical load 3 as described previously. According to a variant embodiment, the electrical load is integrated into the home automation equipment.

The home automation equipment is arranged to cooperate with a remote device 4. The remote device 4 is configured to at least transmit radiofrequency signals representative of control instructions to be executed by the electrical load 3.

The various modes of implementation, various embodiments and variants defined above can be combined in order to generate new modes of implementation and new embodiments of the invention.
