Description

Technical field of the invention

[0001] The present invention relates to the field of home automation systems. More particularly, the present invention relates to a control device and to the pairing of said control device in a home automation system. State of the art

[0002] As is known, document FR1658952A describes a method for pairing a home automation device within a home automation system. The described pairing method includes an initiation step in which the home automation device emits radio frequency waves at maximum intensity. An exchange is then initiated between the home automation device and the control unit.

[0003] However, this solution has limitations.

[0004] Indeed, some home automation devices have a limited power supply due to their low-energy nominal uses. Pairing these devices as described in document FR1658952A risks depleting their power supply, preventing them from functioning normally.

[0005] The present invention aims to resolve all or part of the drawbacks mentioned above. Object of the invention

[0006] The present invention is defined in the independent claims. Other possibilities and embodiments are presented in the dependent claims.

[0007] The arrangement of claim 1 allows the device to use the energy of the incident signal to send the configuration signal. Such an arrangement allows the device to send configuration signals without relying on an internal power source such as a battery or cell.

[0008] This arrangement is suitable for a control device equipped with a power generation system for sending control signals. The power generation system provides a quantity of energy within a first energy range. The converter is arranged to generate a quantity of energy within a second energy range, higher than the first energy range, from the incoming signal. As an example, this embodiment corresponds to a battery-free, wireless control button equipped with a power generation system.

[0009] Specifically, the first energy range is sufficient for sending at least one command frame, particularly for sending a command frame to a receiving home automation device. However, sending configuration signals requires energy in a second range, with values ​​in this second range being higher than those in the first. The converter provides energy in this second range.

[0010] In general, the converter is configured to convert a radio frequency signal into an electrical current.

[0011] In one scenario, the wireless transmitter / receiver is a radio frequency antenna. This arrangement allows for the transmission and reception of wireless signals without a direct line of sight.

[0012] A control signal can be of any kind, such as a synchronization signal, a configuration signal, or a pairing signal, for example.

[0013] According to one possibility, the incident signal is a signal that does not carry useful data.

[0014] In one scenario, the electrical current is direct current (DC). This configuration allows the current to be used directly by the logic processing unit and the transmitter / receiver without requiring conversion. This arrangement also helps to minimize the size of the control device.

[0015] In one scenario, the transmitting device and the receiving device are two separate devices. This configuration allows the transmitting device's energy to be used to send a message to the receiving device.

[0016] Depending on one possibility, the receiving device can be of any kind, such as the central unit of a home automation system, for example.

[0017] According to one embodiment, the device includes an energy smoothing unit configured to smooth the current resulting from the conversion of the incident signal. The smoothing consists of storing a very small amount of energy, on the order of a few hundred µs to 1 ms, for a current of up to 20 mA and an energy of 1 µJ, in order to avoid rapid variations in the inrush voltage of the processing logic unit.

[0018] Such an arrangement allows for both simple configuration, low maintenance and environmental impact due to the absence of a large storage capacity such as a battery, for example, and occasional use of the control device without requiring a large storage capacity such as a battery.

[0019] According to one embodiment, the energy smoothing unit is a capacitor.

[0020] In one embodiment, the energy from the incident signal is stored in the capacitor. Such an arrangement allows a control device including an external power source, such as a solar power supply, to operate even when said external power supply is no longer supplying power to the control device.

[0021] This design allows the device to emit control signals without requiring a battery. This also makes the device more compact and reduces its environmental impact. Furthermore, since batteries have a limited lifespan, this design significantly improves the overall lifespan of the control device.

[0022] According to one embodiment, the configuration message is a pairing message.

[0023] This arrangement allows the energy of the incoming signal to be used to pair the device within the home automation system. Indeed, during normal operation, the control device consumes only a small amount of energy, whereas during pairing, it needs to exchange information with one or more other devices, which requires a significantly larger amount of energy.

[0024] According to one embodiment, the transmitting device from which the incident signal is emitted is a smartphone.

[0025] This design allows the smartphone's energy to be used during the configuration of the control device. Indeed, the energy stored in the capacitor is sufficient to ensure the device's nominal operation. This therefore reduces both the device's size and its environmental footprint.

[0026] The incident signal can be of any type, such as using the 3G, 4G, GSM, GPS, Wi-Fi, or Bluetooth protocol. This setup allows a command or configuration message to be sent using readily available commercial devices.

[0027] According to one embodiment, the incident signal from a transmitting device and the configuration signal sent to the receiving device are of different frequencies.

[0028] Different frequencies are defined as two frequencies between which there is a difference of more than 0.1% or a few MHz. For example, the incoming signal might be at a frequency of around 2.4 GHz, and the configuration signal might be sent at a frequency of around 868 MHz, corresponding to that of a home automation protocol.

[0029] This arrangement allows the transmitter / receiver to send the configuration signal while simultaneously receiving the incident signal. Therefore, this arrangement allows the electrical current resulting from the conversion of the incident signal to be used to send the configuration signal.

[0030] In one embodiment, the incident signal from a transmitting device and the configuration signal sent to the receiving device have the same frequencies. "Same frequencies" means that the frequency of the incident signal and the frequency of the configuration signal differ by less than 0.1% or a few MHz. Specifically, in this case, the control device can be configured to switch from a first operating mode of receiving the incident signal from the transmitting device for energy storage to a second operating mode of transmitting in which the configuration signal is sent to the receiving device.

[0031] Specifically, the switch from the first to the second operating mode occurs when the device has sufficient energy available in the energy smoothing unit to transmit at least one configuration message, and in particular to exchange messages corresponding to a complete configuration of a receiving device. In this case, the smoothing unit acts as an energy storage unit.

[0032] According to one embodiment, the control device is configured to receive and convert the incident signal when the logic processing unit is off.

[0033] According to one embodiment, the converter is configured to generate a binary signal for the logic processing unit.

[0034] According to one embodiment, the value of the generated binary signal depends on the reception state of the incident signal.

[0035] In one configuration, the transmitter / receiver is electrically connected to a first diode, which is configured to conduct in the direction of signal reception. The transmitter / receiver is also electrically connected to a second diode, which is configured to conduct in the direction of signal transmission. The first diode is electrically connected to the converter, while the second diode is electrically connected to the logic processing unit. This arrangement allows the incoming signal to be automatically routed to the converter, even when the logic processing unit is powered off. This arrangement also provides electrical current to power the logic processing unit and to send a control and / or configuration signal, even without an internal power supply to the control device.

[0036] The invention also relates to a method for configuring a control device as defined in claim 11. Such an arrangement allows the device to send configuration messages upon receiving the incident signal combined with the actuation of the actuator unit. This arrangement allows the control device to be placed in a configuration mode only at the user's request. This arrangement prevents situations in which the control device receives an incident signal not intended for it.

[0037] In one scenario, the electrical current is direct current. This arrangement allows the current to be used directly by the logic processing unit and the transmitter / receiver without requiring conversion. This arrangement also helps to minimize the size of the control device.

[0038] This capability allows the energy of the incident signal to be used to configure the device within the home automation system. Indeed, under normal operating conditions, the control device consumes only a small amount of energy, whereas during configuration, it needs to exchange information with the home automation system's central unit more frequently, requiring a significantly larger amount of energy. This increased energy consumption is that of the incident signal.

[0039] In one scenario, the transmitting device and the receiving device are two separate devices. This configuration allows the transmitting device's energy to be used to send a message to the receiving device.

[0040] Depending on one possibility, the receiving device can be of any kind, such as the central unit of a home automation system, for example.

[0041] According to one embodiment, the configuration instruction received at the configuration instruction reception step includes one or more of the following pieces of information: a synchronization pattern enabling the control device to be synchronized with the transmitting device; a header including a protocol version identifier enabling the transmitting device to designate to the control device the transmission protocol used; data such as a network address corresponding to the receiving device for example; and / or a checksum enabling the correct transmission of data to be verified.

[0042] According to one embodiment, the configuration instruction comes from the transmitting device. Brief description of the drawings

[0043] The invention will be even better understood with the aid of the detailed description set forth below, in conjunction with the accompanying drawings, in which: [ Fig. 1 ] represents a control device according to the invention within a home automation system. Fig. 2 [ ] represents an electrical diagram of a control device according to a first embodiment of the present invention. Fig. 3 [ ] represents an electrical diagram of a control device according to a second embodiment of the present invention. Fig. 4 ] is a flowchart representing an execution method for configuring a control device according to a first implementation method of the invention. Fig. 5 ] is a flowchart representing an execution method of a configuration process for a control device according to a second implementation method of the invention. Detailed description

[0044] There figure 1This represents a CMD control device designed to transmit a control signal to a UCE receiving device in a home automation system. For example, the CMD control device could be a home automation control point, such as a control button, and in particular a battery-free and wireless control button or control point.

[0045] As depicted on the figure 2 According to a first embodiment, the CMD control device includes a wireless transmitter / receiver 50. The wireless transmitter / receiver may be a transceiver used by the control device to send control signals. The transmitter / receiver is configured to receive an incident signal from a transmitting device ORD as shown in the figure 1The transmitting device ORD is preferably a smartphone. For the purposes of this invention, the receiving device UCE is a central unit of the home automation system.

[0046] The CMD control device also includes an actuation unit 58 configured to receive a configuration instruction from a user service record (USR). For example, the actuation unit may include a touchscreen or a keyboard with multiple keys, where actuation corresponds, for instance, to a key combination. The actuation unit may also include a pairing button.

[0047] The control device also includes a logic processing unit 52 adapted to decide whether to transmit the control signal via the wireless transceiver 50, which has a single antenna. This unit is configured to receive a configuration instruction from the actuation unit and generate at least one configuration message to be transmitted to the receiving device (UCE). The wireless transceiver 50 is also configured to transmit at least one configuration message to the receiving device (UCE). The wireless transceiver 50 is a radio frequency antenna. This arrangement allows for the transmission and reception of wireless signals without a direct line of sight.

[0048] The CMD control device also includes a converter 56 configured to convert the incident signal into electrical current and to power the logic processing unit 52 using said electrical current. Specifically, the converter 56 is configured to convert a radio frequency signal into direct current. This arrangement allows the CMD control device to use the energy of the incident signal to send the configuration signal. This arrangement enables the CMD control device to send configuration signals without requiring an internal power source such as a battery.

[0049] According to one embodiment, the converter 56 is also configured to generate a binary signal for the logic processing unit 52. The generated binary signal depends on the reception state of the incident signal.

[0050] According to one embodiment, when an incident signal is received by the wireless transceiver 50 and the converter 56 converts said incident signal into an electrical current, the converter 56 generates a binary signal equal to one for the logic processing unit 52. Conversely, when the converter 56 does not convert any incident signal, said converter generates a binary signal equal to zero.

[0051] In one embodiment, the binary signal generated for the processing logic unit 52 is read by said processing logic unit at a predetermined interval, such as every 20 ms, for example. This arrangement allows a configuration message containing one or more pieces of information to be sent via one or more incident messages.

[0052] Thus, a frame is made up of a succession of binary signals which can contain a wake-up signal, a synchronization pattern, a header, data, and a verification code (CRC-4).

[0053] Preferably, the wake-up signal comprises four signals equal to 1, so as to provide enough energy to process the signals to come.

[0054] The 56 converter is suitable for converting incident signals of any type, such as those using 3G, 4G, GSM, GPS, Wi-Fi, or Bluetooth protocols. This configuration allows for the transmission of control or configuration signals using readily available commercial devices.

[0055] In one embodiment, the electric current is a direct current. This arrangement allows the current to be used by the logic processing unit 52 and the transmitter / receiver 50 without requiring further conversion. This arrangement also helps to minimize the size of the CMD control device.

[0056] The CDM control device also includes a power smoothing unit 54, configured to smooth the current resulting from the conversion of the incident signal. The power smoothing unit can be of any type, such as a capacitor or a capacitor.

[0057] The CDM control device may include or be associated with also an electrical power generation system 59, particularly in the previously mentioned example of a battery-free and wireless control point.

[0058] The electrical power generation system 59 is configured to power components of the device, and in particular the logic processing unit, in order to enable the transmission of a control signal. For example, this could be an electrodynamic generator or a piezoelectric generator. Under normal operating conditions, the power generation system is capable of supplying a limited but sufficient amount of energy to send a command frame to a receiving home automation device. The generator can be powered, for example, by the mechanical energy corresponding to the pressure of a control button. The amount of energy generated for sending the control signal falls within a first range of values, which is lower than a second range of values ​​corresponding to a configuration process, provided by the converter 56.

[0059] For the purposes of this invention, an incident signal is a message that does not carry useful data. That is to say, the signal's sole purpose is to be converted and it therefore does not transmit any useful data to the CMD control device. Thus, any message transmitted in any protocol can be used because only its conversion into energy matters.

[0060] The CMD control device is suitable for sending a control signal. A control signal can be of any kind, such as a signal to open a door or deploy sunshades, for example.

[0061] In one embodiment, the transmitting device ORD and the receiving device UCE are two separate devices. This configuration allows the energy of the transmitting device ORD to be used to send a message to the receiving device UCE. In one embodiment, the receiving device UCE can be of any type, such as the central processing unit of a home automation system, for example.

[0062] According to the first embodiment presented to the figure 2The incident signal from a transmitting device (ORD) and the configuration signal sent to a receiving device (UCE) are at different frequencies. This arrangement allows the wireless transceiver 50 to send the configuration signal while simultaneously receiving the incident signal. Therefore, this arrangement allows the electrical current resulting from the conversion of the incident signal to be used directly to send the configuration signal, all while using the same antenna.

[0063] In this embodiment, the CMD control device is configured to receive and convert the incident signal when the processing logic unit 52 is powered off. This arrangement allows the incident signal to be automatically routed to the converter, even when the processing logic unit is powered off. This arrangement also provides electrical current to power the processing logic unit and to send a control and / or configuration signal even without an internal power supply to the control device.

[0064] This arrangement allows the CMD control device to use the energy from the incident signal to send a configuration or control signal. This arrangement also allows the CMD control device to send configuration or control signals without relying on an internal power source such as a battery. Furthermore, this arrangement results in a CMD control device with a simple and compact architecture.

[0065] The first embodiment corresponds to a scenario in which the incident signal from a transmitting device (ORD) and the configuration signal sent to a receiving device (UCE) have different frequencies. However, the closer the frequencies of the incident signal from the transmitting device (ORD) and the configuration signal sent to the receiving device (UCE) are, the greater the antenna gain and the greater the electrical energy resulting from the conversion of the incident signal.

[0066] According to a second embodiment presented to the figure 3The transmitter / receiver is single-band, and / or the incident signal and the configuration message are on the same frequency. In this case, it is not possible to transmit and receive simultaneously on the same frequency using a single wireless transmitter / receiver 50. According to this second embodiment, the CDM control device also includes a wireless transmitter / receiver 50, a converter 56, a logic processing unit 52, an actuation unit 58, and an energy smoothing unit 54.

[0067] The wireless transmitter / receiver 50 is electrically connected to a first diode 60, said first diode 60 being configured to conduct in the direction of receiving the incident signal. The wireless transmitter / receiver 50 is also electrically connected to a second diode 62, said second diode being configured to conduct in the direction of transmitting the signal. The first diode 60 is electrically connected to the converter 56, while the second diode 60 is electrically connected to the logic processing unit 52.

[0068] In other words, the wireless transmitter / receiver 50 is passively connected to the converter 56.

[0069] These provisions make it possible to obtain a control device configured to receive and convert the incident signal when the logic processing unit is off in the case of the second embodiment in which the configuration message and the incident signal are on the same frequency.

[0070] Furthermore, diodes 60 and 62 are controlled by the logic processing unit 52. These arrangements allow the logic processing unit to switch the device from a mode of receiving the incident signal intended for energy storage, to a mode of transmitting in which the configuration signal is transmitted to the receiving device when the device has sufficient energy available in the energy smoothing unit 54 which in this case corresponds to an energy storage unit.

[0071] The configuration message is a pairing message. This arrangement allows the energy of the incoming signal to be used to pair the CMD control device within the home automation system. Indeed, during normal operation, the control device consumes only a small amount of energy, whereas during pairing, it needs to exchange data with one or more other devices, requiring significantly more energy. For example, the energy required to send a frame is on the order of 0.5mW to 1mW, while the configuration procedure can require tens to tens of milliwatts, as the transmission of several successive frames is necessary.

[0072] The invention also relates to a method for configuring a CMD control device intended to emit a control signal to a home automation system as shown in the figure 4The control process is executed by the CMD control device and includes: a stage of receiving an incident signal AORD1 from a transmitting device ORD; a stage of converting the incident signal ACMD1 into electrical current; a stage of receiving a configuration instruction AUSR2; and a configuration stage ACMD2 in which the control device CMD transmits at least one configuration message ACMD3 to a receiving device UCE in the home automation installation using the electrical current from the ACMD1 conversion of the incident signal.

[0073] This arrangement allows the control device to be put into a configuration mode only at the user's request. This arrangement prevents situations in which the control device receives an unexpected signal not intended for it.

[0074] This arrangement allows the energy of the incident signal to be used to configure the CMD control device within the home automation system. Indeed, under normal operating conditions, the CMD control device consumes only a small amount of energy, whereas during its configuration, it requires numerous exchanges with the home automation system's central processing unit, thus demanding significantly more energy. This increased energy consumption is that of the incident signal converted during the ACMD1 conversion stage.

[0075] According to one embodiment, a user performs an approach step AUSR1 of the transmitting device ORD to the control device CMD, thus enabling the transmitter / receiver 50 to receive a stronger signal. As a result, the transmitting device ORD is located at a distance of 2 cm to 3 cm from the control device CMD.

[0076] In one embodiment, the transmitting device ORD receives an acknowledgment signal from the receiving device UCE during an acknowledgment step AUCE2. The acknowledgment signal confirms the correct configuration of the control device CMD. This arrangement informs the user when it is safe to move the transmitting device ORD away from the control device CMD.

[0077] There figure 5 represents a second embodiment of the invention, corresponding in particular to a case in which the incident signal and the configuration message are on the same frequency. The steps described with reference to the figure 4The provisions concerning the first embodiment are retained. However, the ACMD1 conversion step includes an energy storage step in the smoothing unit 54. Thus, energy is stored over a period of approximately 20 ms to 100 ms, for a current of up to 20 mA and an energy ranging from 40 mJoules to several hundred mJoules. This arrangement allows sufficient energy to be stored to perform the ACMD2 configuration step as shown in the diagram. figure 5 This arrangement therefore ensures complete configuration of the control device, even if the wireless transceiver 50 no longer receives an incident signal. As previously mentioned with reference to the figure 3, the device switches from a mode of receiving the incident signal intended for energy storage, at the end of the ACMD1 step, to a mode of transmitting in which the configuration signal is transmitted to the receiving device when the device has sufficient energy available in the energy smoothing unit 54 which in this case corresponds to an energy storage unit.

[0078] Thus, the arrangements according to the invention make it possible, by using an external energy source not requiring the addition of specific connection equipment, to provide sufficient energy to a control device, such as for example a battery-free and wireless control point to perform pairings with other devices according to common protocols (Zigbee, IO Homecontrol) even if the frames used are often long and are also repeated a large number of times (3 to 20 or even more).

[0079] The arrangements according to the invention make it possible to ensure the correct configuration of the control device since only a few milliwatts, in other words more than one milliwatt, are necessary for the transmission of configuration frames whereas a smartphone emits on the order of 500 mW and up to 2000 mW.

[0080] As an example, the invention is particularly well-suited for a battery-free and wireless control point whose power generation system, under normal operating conditions, is only capable of supplying a limited but sufficient amount of energy to send a command frame to a receiving home automation device. This type of power generator is, for example, an electrodynamic or piezoelectric generator. The initial range of available power for this type of generator is between 0.5 mW and 1 mW. The device of the invention is thus added to the control point to facilitate the configuration procedure of the control point within the home automation system. Both can share the same radio circuit and antenna. The actuation unit can be one or more buttons pressed simultaneously on the control point to initiate the configuration procedure for the device of the invention.

[0081] According to another example, the invention also allows for occasional use of the control device without requiring a large storage capacity such as a battery. Such an arrangement is, for example, suitable for a solar protection control device when the solar protection is only activated one week per year. Indeed, the CMD control device consumes only a very small amount of energy during nominal operation. An energy smoothing unit might then suffice in certain situations.

[0082] The smartphone used to supply power to the control point via radio waves can be advantageously used with specific software to facilitate the configuration process. This software will allow the transmission of successive frames, which the control point will use to convert them into energy. Communication between this receiving device (UCE) and the smartphone (ORD) will be possible, confirming the successful completion of the configuration process and signaling its end to stop the transmission of unnecessary frames. The smartphone's battery life will therefore be minimally affected.

[0083] In one embodiment, the incident signal comprises a plurality of frames. Such a configuration allows the converter 56 to convert a greater quantity of energy and thus supply the logic processing unit 52 with sufficient power to perform the ACMD3 configuration step.

[0084] According to one embodiment, the step of receiving an incident signal AORD1 is repeated during the process, for example after the step of receiving a configuration instruction AUSR2. Such an arrangement makes it possible to obtain the energy necessary to carry out the different steps of the process without requiring large storage capacities.

[0085] In a specific example, the process includes: a step of receiving an incident signal AORD1, comprising four frames, from a transmitting device ORD; a step ACMD1 of converting the incident signal, comprising four frames, into electrical current, such an arrangement makes it possible to obtain the energy necessary to carry out the different steps of the process; a step of receiving a configuration instruction AUSR2; a configuration step ACMD2 in which the control device CMD transmits ACMD3 at least one configuration message to a receiving device UCE in the home automation installation using the electrical current resulting from the conversion ACMD1 of the incident signal comprising four frames; a step of receiving an incident signal comprising a control instruction, from the transmitting device ORD; a step of converting the incident signal comprising a control instruction into electrical current;a demodulation step of the incident signal including a control instruction; a control step, in which the control device CMD transmits at least one control message to the receiving device UCE using the current resulting from the conversion of the incident signal including a control instruction.

[0086] The command step is carried out on the basis of the demodulated command instruction.

[0087] According to one embodiment, the configuration instruction received at the AUSR2 configuration instruction reception step includes one or more of the following pieces of information: a synchronization pattern enabling the control device CMD to synchronize with the transmitting device ORD; a header including a protocol version identifier enabling the transmitting device to designate to the control device the transmission protocol used; data such as a network address corresponding to the receiving device UCE for example; and / or a checksum enabling verification of the correct transmission of data.

[0088] According to one embodiment, the incident signal and the configuration instruction are transmitted according to the Bluetooth protocol, and more specifically, "Bluetooth Advertising".

[0089] According to one embodiment, the configuration instruction comes from the ORD transmitting device.
