Abstract

The system provides remote control of appliances without need for extra controls or wiring. The system for controlling electrical appliances (L1, L2) uses a switch which also controls an existing electrical appliance (A). This may, for example, be the bulb providing normal lighting in a room. At least one logic analyzer is designed to analyze directly or indirectly the levels of an electrical characteristic generated by the switch. When the switch is triggered a predetermined number of times at short intervals, this information is detected and used to activate a device an activation/de-activation module (MAD) which is connected between the secondary controlled appliances (L1, L2) and their respective power supplies (P1, P2).

Description

The field of the invention is that of home automation.

More specifically, the invention relates to remote control systems for electrical appliances (lamps, televisions, computers, electric shutters, etc.), using the standard switch of an existing electrical network. Two configurations are then possible - the system comprises a retransmission module fixed on a lighting socket, emitting a signal characterized by a frequency as soon as it is energized. The electrical state changes of the light socket are detected from the reception or not of the signal by a remote control module. The latter directly controls an electrical device transmits control signals to activation / deactivation modules placed in series between a power source and an electrical device to be activated / deactivated, according to the detected electrical state changes. - System includes a local control module fixed on a lighting socket, driving several electrical devices by issuing control signals according to the detected electrical state changes.

These systems characterize the state of the art have two major drawbacks - The remote control module produces the same signal for the activation and deactivation of a given electrical device. It is then necessary for the activation / deactivation module or the remote control module, placed in series between the electrical device to be switched on / off and the power source, to activate the device after a first reception of the control signal. and deactivates it after a second reception of the same control signal. However, many activation / deactivation modules, operating in various home automation applications, are designed to respond to different activation and deactivation signals, which poses serious compatibility problems, is not planned device turning off the light bulb when using a retransmitter module. This power off is however desirable for any configuration because it avoids a blinking effect after a multiple support (very close pressures at the switch, intended to activate a control stage).

The invention particularly aims to solve these problems of the state of the art.

More specifically, the objective of the present invention is to provide a control system having generally the same characteristics as the aforementioned systems, by adding some technical specificities, including a better compatibility with other home automation applications and more extensive functionality. This invention makes it possible, for example, to facilitate the control of electric shutters or to control the variation in light intensity of a light bulb, thanks to an increased choice of control signals.

Another object of the invention is to avoid the inadvertent wear of light bulbs connected to a retransmission module.

These various objectives, as well as others which will appear subsequently, are achieved according to the invention with the aid of a remote control system of at least one electrical appliance, which type comprises: state of a switch-controlled electrical connection element; means for controlling activation / deactivation means of said at least one electrical device, as a function of the detected state changes.

Preferably, in at least one operating mode, the first and second pulses caused by said switch successively cause the emission of said activation signals and in that in said at least one operating mode, the third and the fourth pulse caused by said switch successively cause the emission of said deactivation signals.

 Optionally, means (for example switches) may be provided which allow the user to select the number of control signals transmitted at each operating mode, namely: a single signal, two distinct signals, three distinct signals or four separate signals. This capability allows you to adapt to the user's requirements by enhancing the compatibility of the system with other home automation applications in operation.

Preferably, said distinct control signals may be continuous or pulsed.

Advantageously, the activation / deactivation of an electrical device may also consist of a setting, continuous or not, of at least one operating parameter of said device. The applications of this characteristic are numerous, for example control of electric shutters, or the control of the variation of luminous intensity of a lamp.

Preferably, an electrical apparatus is activated after a particular multiple support by transmitting a first transition signal, and is deactivated after renewal of said particular multiple support by transmitting a second transition signal.

FIG. 10 is a simplified diagram of a fourth embodiment of a control system according to the present invention; FIGS. 11 and 12 show a plurality of time diagrams making it possible to explain a example of management of the state signals in the second embodiment.

Now, with reference to FIGS. 1, 2, 4, 5 and 6, the first use configuration according to a first embodiment of a control system according to the present invention is presented.

In this first configuration, the remote control system comprises a retransmission module MR, a remote control module MCD and a plurality of activation / deactivation modules MAD2, MAD3 (not represented), ...

Each activation / deactivation module MAD2 MAD3 (not shown), ... is placed in series between a socket P2, P3 (not shown), ... and a lamp L2, L3 (not shown). .. to enable / disable. More generally, it can be placed in series between any power source and one (or more in series) electrical device (s) any (s). Referring to the diagrams, the system comprises a retransmission MR module for transmitting signals SEH 'or SEB' as a function of the successive electrical states of the socket D. In other words, this module MR receives state signals SEH , SEB in the form of a voltage associated with each one (220V for SEH and OV for SEB) and then retransmits them in another form SEH ', SEB' (use of the technique of carrier currents, of the technique of radio waves or of another technique). In the example shown in FIG. 1, the MR module is interposed between the electric bulb A and the socket D, but it can generally be adapted to any level of the electrical circuit controlled by the switch I.

The system comprises a remote control module MCD capable of receiving the state signals SEB 'and SEH' emitted by the retransmission module MR. In the example presented, when the socket D is energized, the retransmission module N # emits a determined signal received by the remote control module MCD and interpreted as a high state signal (SEH '). On the other hand, when the socket is no longer powered, the remote control module MCD no longer receives the predetermined signal, which it interprets as a low state signal (SEB '). In other words, the remote control module MCD controls the different activationdeactivation modules MAD2, MAD3 (not shown), ... as a function of the pressures on the switch I, thanks to the signals received by the retransmission module N #. In the example shown in the figure it is adaptable to an electrical outlet Pl.

 The remote control module MCD allows to activate an advanced mode after a particular multiple support (at least two consecutive very close pressures causing two changes of electrical state). Each advanced mode is activated by a particular multiple support; the system then switches from the basic mode for the usual lighting control to the advanced mode for the control of the electrical apparatuses L1, L2, L3 (not shown).

In the particular embodiment shown in FIG. 2, the retransmission module MR comprises means 1 for turning off the light bulb and means 2 for transmitting re-issued state signals SEH ', SEB'. function of the successive states of the sleeve D.

The remote control module MCD comprises - means 3 for receiving the re-transmitted state signals, SEB '; means 4 for detecting electrical state changes, from the retransmitted state signals SEH 'and SEB' received; means 6 for controlling, according to the detected state changes, activation / deactivation means. These control means 6 themselves comprise means 65 for transmitting control signals.

Furthermore, each activation / deactivation module (as illustrated for MAD2 in FIG. 2) comprises, in addition to the activation / deactivation means, means 9 for receiving the control signals.

 Optionally, and as illustrated in FIGS. 1 and 2, the remote control module MCD may furthermore comprise other activation / deactivation means 5, controlled directly by the control means 6, so as to enable / disable at least one other electrical appliance. The remote control module MCD is then placed in series between a power source (socket P1) and this other electrical device (lamp LI). For this (see Figure 6), one or more channels of the multiplexer can directly control the relay device 68 via the latch device 64 to turn on or off the lamp L <B> I. </ B>

The system according to the invention may have a basic mode as well as one or more advanced modes.

The basic mode is automatically engaged as soon as the user makes a single press on the switch I (ie without specific manipulations). allows the bulb A to be controlled normally.

An advanced mode is engaged when the user performs a particular multiple press (two, three or four very close presses) on the switch 1. Each particular multi-press allows to select a different advanced mode. In the example presented in FIG. 1, the selected advanced mode makes it possible to control two lamps L2, L3 (not represented), by the emission by the transmission means 65 (cf. FIG. 6) of the following four control signals : two activation signals SA2, SA3 respectively emitted after a first and a second pressure spaced apart on the switch and two deactivation signals SD2, SD3 respectively emitted after the third and fourth following spaced apart pressures.

Note also that the signals SA2 and SD2 as well as the signals SA3 and SD3 may be identical if one chooses to use activation / deactivation modules activated at the first reception of a control signal and deactivating at second reception of the same control signal.

In summary, advanced mode operation is as follows - after first pressing the switch, bulb A and lamp L2 light up; - After a second press on the switch, bulb A goes out and lamp L3 (not shown) comes on; - after a third press on the switch, the bulb A comes on and the lamp L2 goes off <B>; </ B> - after a fourth press on the switch, the bulb A and the lamp L3 (not shown) go out.

The step of transition between the basic mode and the advanced mode also makes it possible to control another lamp L4 (not represented), by virtue of the emission by the aforementioned transmission means 2 of the following two control signals: a signal ST1 (not shown), issued at each first detection of a particular multiple support (rapid succession of at least two pressures on the switch) and a signal ST2 (not shown), issued at each second detection of the same support multiple (ST1 and ST2 may also be identical). In summary, the operation of a transition step is as follows: after a first particular multiple press, the selected advanced mode is activated and L4 lamp (not shown) lights up; - After second particular multiple support or a second long press, the third lamp L4 (not shown) goes off.

Note that two other electrical devices (not shown) can optionally be activated via the basic mode that can operate in the same process as the advanced mode.

A specific embodiment of the retransmission module MR, inserted between the socket D and the bulb A or placed at any other level of an electrical circuit controlled by FIG. 4, is discussed in detail in connection with the simplified diagram in FIG. a switch. It contains the means 2 for transmitting re-issued state signals SEH ', SEB', and the means 1 for turning off the light bulb A. The means 1 for turning off the light bulb illumination A comprises: a state change detector 11, a calibrated pulse generator 12, a logic analyzer 13 and a relay 14. The transmitter 2 transmits through the electrical network or through radio waves, a continuous HF signal, as long as a voltage is applied to the socket.

The state change detector 11 detects changes in the state of the mains supply by producing a separate unscaled pulse at each changeover from 0 V to 220 V and vice versa. The pulses caused by the changeover from 0 to 220 V and the passage from 220 V to 0 V are respectively called connection pulse and disconnect pulse.

The calibrated pulse generator 12 allows the calibration of the connection pulses C1, C2 disconnection and C3 deactivation of the bulb A.

The logic analyzer 13 allows the calibrated pulse generator to emit a deactivation pulse of the relay when the calibrated disconnection connection pulses are superimposed. This pulse is maintained for a specific time corresponding to the operating time of the advanced mode.

Relay 14 is directly controlled by the aforementioned pulse. It disables the lighting bulb A as long as the system is in advanced mode. Relay 14 also automatically deactivates bulb A by virtue of the deactivation pulse emitted during a delay corresponding to the duration of each calibrated connection pulse (passage from 0 V to 220 V). This procedure avoids a blinking phenomenon of bulb A, but also any unwanted control of electrical devices managed by the basic mode when switching to advanced mode.

Note also that the aforementioned embodiment of the MR module not containing a counter can also be used within the remote control module for the procedure of switching to advanced mode, essentially in the case where the system requires only one mode. advanced to operate (for example, control of electric shutters or control of the light intensity of a light bulb).

In connection with the plurality of time diagrams of FIG. 5, an example of pulse management within the retransmission module MR presented above and illustrated in FIG. 4 is now explained. In FIG. 5, C and D signify connection and disconnection respectively.

The first timing diagram 51 represents the successive electrical states of the socket D.

The second timing diagram 52 represents the total of unsized connection and disconnection pulses. The third timing diagram 53 represents the calibrated connection pulses. Each unconnected connection pulse generates a calibrated connection pulse.

The fourth timing diagram 54 represents the calibrated disconnection pulses. Each unconnected disconnect pulse generates a calibrated disconnect pulse.

The fifth timing diagram 55 represents the deactivation pulses of the relay. Each relay deactivation pulse is generated during the duration of the connection pulses but also when the calibrated connection pulses and the calibrated disconnection pulses are superimposed (hatched area in FIG. 5). This deactivation of the relay continues for a time corresponding to the duration of the advanced mode.

We now discuss in detail, in connection with the simplified diagram of Figure 6, a particular embodiment of the remote control module MCD. It includes the means 3 for receiving the re-transmitted state signals, the means 4 for detecting electrical state changes from the received signals and the control means 6. In addition to the means 65 for transmitting control signals, the control means 6 comprise: a counter 61, a memory 62, a multiplexer 63, a latch system 64, a time base 66, a filter 67, a relay device 68 and two selectors S 1 and S 2.

The receiver 3 receives the re-transmitted state signals SEB 'and SEH' from the retransmission module MR.

The state change detector 4 detects the changes in the electrical state (voltage) of the socket (0 V to 220 V, or 220 to 0 V) from the data supplied by the receiver 3 and transmits impulse not calibrated after each change of state detected (SEB 'corresponds to 0 V and SEH' to 220 V).

The time base 66 calibrates the control pulses (see definition below), transition, control and counting, depending on the detected state changes.

The counter 61 counts the pulses received by the time base 66 during a delay set by the control pulse. This calibrated pulse activates the counter 61 for a relatively short time, which allows to count the very close pressures on the switch. The memory 62 makes it possible to store the data supplied by the counter 61 while transmitting them to the address inputs 631 of the multiplexer 63. This part of the circuit makes it possible to store the control stage (ie advanced modes). during a programmable delay after the last pulse detected. After this time, the memory is cleared and the system returns to basic mode.

The filter 67 allows the passage of a transition pulse when it detects through the counter 61 a particular multiple support a first time and when it detects the same multilple particular support a second time. thus blocking the passage of pulses produced by normal spaced bearings. If even particular multi-support is required for activation and deactivation of an advanced mode, the filter 67 authorizes the initialization of the memory 62 only after having detected twice that same particular multiple support.

The multiplexer 63 manages the pulses delivered by sending them to the selected outputs (W 1, W 2, W 3, X 0, Y 0, X 1, Y 1, X 2, Y 2, X 3, Y 3, Z 1, Z 2 or Z 3). The inputs X and Y are intended to receive the activation and deactivation pulses whereas the inputs Z and W are respectively associated with the initialization and transition pulses.

The latch device 64 alternately selects an activation signal and a deactivation signal from the same output of the multiplexer 63. The control signal transmitter 65 makes it possible to transmit the various control signals simultaneously or separately. deactivation activation (SA2, SD2, SA3, SD3, ST1, ST2, ...) through the channels 631.

The selector S1 makes it possible to associate one of the outputs W1, W2, W3 with all the channels generating the different deactivation signals (SD2, SD3, ST2,...) Or with the set of channels generating the signals. activation (SA2, SA3, ST1, ...). This arrangement makes it possible to deactivate or activate all the devices controlled by the system by means of a particular multiple support.

The selector S2 makes it possible to connect one of the outputs Z1, Z2, Z3 to ground in order to initialize the memory 62 following a predetermined multiple support. This device therefore allows a manual return in basic mode if the automatic return procedure in basic mode is not chosen. The relay device 68 makes it possible to activate / deactivate directly an electrical apparatus connected to the remote control module MCD, from the system of flip-flops 64.

A second configuration of use of a control system according to the present invention is now presented in connection with FIG. This differs from the first configuration presented above only in that only two separate signals SA4 and SD4 are emitted within the operating mode used. To do this, it suffices to deactivate the latch system 64 (see FIG. 6).

A particular multiple support allows to go into advanced mode (for example two very close presses on the switch I). Then, a new pressure will cause the emission of said control signal SA4 which activates, for example, the descent of the electric roller shutter VR. The following pressure allows the transmission of said control signal SD4 which activates, for example, the raising of the shutter VR.

It is thus possible to adjust the closure of the roller shutter as needed. After a new specific multiple support identical to the first or different, the system returns to basic mode and the shutter remains locked in the chosen position.

In FIG. 3, the shutter VR is controlled by means of a motorization device MVE, comprising means 15 for receiving the control signals produced by the remote control module MCD and means 16 for activating / deactivating the shutter. based on the signals (SA4, SD4) received by the remote control module MCD. Of course, the remote control module can also directly control the electric shutter by the relay device 68 shown in FIG. 6.

Such a method of using the control system according to the present invention can also be applied for the light intensity variation control and more generally for any adjustment of the operating parameters of an electrical appliance.

Next, with reference to FIGS. 7 and 8, is a second embodiment of a control system according to the present invention. This differs from the first embodiment presented above only in that the retransmission module MR 'can simultaneously transmit two high state signals SEH'A and SEH'B distinct when the lighting socket is energized. As a result, the retransmission module MR 'contains, in addition to the means 1 for switching off the light bulb, transmission means 2' capable of simultaneously transmitting two re-transmitted high state signals SEH'A and SEH'B characterized by separate emission frequencies.

The remote control module MCD 'contains receiving means 3' capable of simultaneously or separately receiving the two high state signals SEH'A and SEH'B. furthermore contains means 4 'for detecting the state changes of the re-transmitted signals SEB' (not shown in FIG. 7), SEH'A, SEH'B; control means 6 'comprising means 65' for issuing control commands, and outputs 7 '.

An example of an application using this device is illustrated in FIG. 8, where the system according to the present invention makes it possible to drive two electric shutters VR1, VR2 from standard switches 11, 12 usually controlling two lighting sockets D1 and D2. There are two retransmission modules MR '1, MR'2; two remote control modules MCD '1, MCD'2; as well as two motorisation devices MVE1, MVE2.

The state signals SEH'Al and SEH'A2 emitted by the retransmission modules MR '1 and MR'2 do not have the same frequency. The retransmitted high state signal SEH'A1 can only be received by the remote control module MCD '1 and the retransmitted high state signal SEH'A2 can be received only by the remote control module MCD'2. On the other hand, high state signal SEH'B is emitted by the two retransmission modules N # '1, MR'2 can be received by the two remote control modules MCD'1, MCD'2. The control of the shutter VR1 by the remote control module MCD 'l and the shutter VR2 the control module MCD'2 can be activated indifferently by a first and second advanced mode, one for the selective control of a specific shutter and the other to the general command of all the shutters. The first advanced mode will be activated after a particular multiple support thanks to the state signals SEB ', SEH'A (SEH'Al, SEH'A2) which can only be received by a particular remote control module MCD', while the second advanced mode will be activated following another particular multiple support via status signals SEB ', SEH'B recognizable by all remote control modules MCD' (MCD '1, MCD'2). It then suffices to reserve a first advanced mode for the selective control of each component VR1, VR2 from each switch 12 and to reserve a second advanced mode for the global two-component control VR1, VR2. In the example presented, two very close presses switch 11 and on the switch 12 make it possible to selectively and respectively control the shutter VR1 and the shutter VR2 according to the process described above. By cons, four very close pressures on one of the switches I1 12 allow the control of both shutters VR1, VR2 at a time. It is thus possible to control one or more shutters from a single switch. More generally, this particular embodiment control system according to the present invention can "used for the lective or global control of one or more electrical appliances of any kind from a single switch.

In relation to the plurality of time diagrams of FIGS. 11 and 12, an example of management of the state signals between retransmission modules 1, MR'2 and the remote control modules MCD '1, MCD'2, is now explained. within the second embodiment presented above and illustrated in Figures 7 and 8.

The first time diagram <B> 111 </ B> represents the status signals received by the retransmission module M # '1. 1.

The second timing diagram 112 represents the re-transmitted state signals SEH'A1, SEB 'received by the remote control module MCD' 1.

The third timing diagram 113 represents the re-transmitted state signals SEH'B, SEB 'received by the remote control module MCD'2.

The fourth timing diagram 114 represents the output of a possible state change counter included in the control means 6 '(not shown).

The fifth timing diagram 115 represents the activation of the two advanced modes of the remote control module MCD '1 as a function of the received state signals SEH'Al, SEH'B, SEB' and counted state changes.

The sixth timing diagram <B> 116 </ B> represents the activation of one of the two advanced modes remote control module MCD'2 as a function of the state signals SEH'B, SEB'recived state changes counted .

The timing diagrams 121 through 126 shown in FIG. 12 illustrate the process of managing the state signals between the module MR'2 and the remote control modules MCD '1, MCD'2, according to FIG. principle presented in Figure 11.

On présente maintenant en détail, en relation avec le schéma simplifié de la figure 9, un mode de réalisation particulier du module de commande distant MCD' comprenant des moyens 3' de réception capables de recevoir simultanément ou séparément les deux signaux d'état hauts SEH'A et SEH'B et de les transformer en un signal d'état haut SEH'U unique à destination des moyens 4' de détection de changements d'état. Un changement d'état de l'élément de branchement électrique associé au module de réémission MR' donc détecté par le passage d'un signal d'état haut SEH'U à un signal d'état bas SEB' (non représenté). Dans ce mode de réalisation particulier, les moyens 3' de réception sont associés à des moyens 67' d'analyse compris dans les moyens 6' de pilotage et destinés à activer un premier mode avancé prédéterminé si les deux signaux d'état distincts SEH'A et SEH'B sont reçus simultanément. De ce fait, les moyens d'analyse sont -mêmes associés aux sorties 7' afin d'activer ou désactiver la sortie correspondant au premier mode avancé. Ce premier mode avancé permet la commande individuelle de chaque module de commande distant à partir d'un interrupteur particulier. Par contre, un second mode avancé est toujours activé après un appui multiple particulier, permettant ainsi commander tous les modules de commande distants à la fois. moyens 65' de 'lection et d'émission d'ordres de commande remplissent les mêmes fonctions que celles décrites pour les modes de réalisation précédents. The following summary table summarizes the operation of the remote control modules MCD'l, MCD'2 as a function of the state signals SEH'Al, SEH'A2, SEH'B, SEB 'retransmitted by the retransmission modules MR' 1, MR'2 and the number of state changes detected.

A and SEH'B and transform them into a single high state signal SEH'U for the state change detection means 4 '. A change of state of the electrical connection element associated with the retransmission module MR 'thus detected by the passage of a high state signal SEH'U to a low state signal SEB' (not shown). In this particular embodiment, the receiving means 3 'are associated with analysis means 67' included in the control means 6 'and intended to activate a first predetermined advanced mode if the two separate state signals SEH' A and SEH'B are received simultaneously. As a result, the analysis means are themselves associated with the outputs 7 'in order to activate or deactivate the output corresponding to the first advanced mode. This first advanced mode allows the individual control of each remote control module from a particular switch. On the other hand, a second advanced mode is always activated after a particular multiple support, thus making it possible to control all the remote control modules at the same time. means 65 'for selecting and issuing control commands perform the same functions as those described for the previous embodiments.

FIG. 10 shows a simplified diagram of another possible embodiment of the remote control module MCD 'named this time MCD' In this configuration, the remote control module MCD "contains detection means 4" A, 4 " B for detecting state changes, each associated with a separate receiver included in the means 3 "for receiving the re-transmitted state signals SEB '(not shown), SEH'A, SEH'B, the data provided by the means 4 "A detection of state changes allow the activation of the first advanced mode while those provided by the means 4" B contribute to the activation of the second advanced mode.For this purpose, the means 6 "of control may contain, in addition to the means 65 "for selecting and issuing control commands, two separate devices for counting the detected changes of state (not shown).
