Definitions

  • the present invention relates to a method of coupling / decoupling between a transmitter and a receiver communicating over a wireless link.
  • the invention also relates to a receiver that can be used in the method of the invention.
  • the light control by wireless connection is achieved through a transmitter communicating with a receiver with an output to send the ignition command to a lamp.
  • the transmitter must be known to the receiver.
  • a coupling process between the transmitter and the receiver must therefore be implemented before normal use of the transmitter / receiver unit. If the same receiver is associated with several transmitters, for example to control several lamps, a coupling must be made between each transmitter and the receiver.
  • the patent application US2004 / 061591 describes for example a method for coupling new transmitters to a receiver. In this document, a new transmitter is added by first activating a transmitter already known to the receiver and then, in a specific time window, by activating the transmitter to be added.
  • Patent application GB2336045 also describes a coupling method implemented by using a particular transmitter to configure the receiver to add new transmitters. These solutions of the prior art are unsatisfactory because they require that at least one of the transmitters is already known to the receiver. Other methods of entering a code for each transmitter or manipulating several buttons of the transmitter also exist. However, these are often not simple to implement. In addition, in the methods of the prior art, the deletion of a transmitter associated with the receiver is often very complicated.
  • the object of the invention is to provide a method of coupling / decoupling between a transmitter and a receiver communicating through a wireless link, which is reliable, safe, intuitive and simple to implement by an unskilled installer.
  • a coupling / decoupling method between a transmitter and a receiver able to communicate with each other over a wireless link comprising the following steps: transmission of a first signal by the transmitter, transmission of a second signal by said transmitter, amplitude processing by the receiver of the first signal and the second signal received and recording or deletion by the receiver of an identification code of the transmitter according to the processing performed.
  • the processing consists in comparing in amplitude the first signal or the second signal received by the receiver with a first threshold value.
  • the processing also comprises comparing an amplitude variation between the first signal and the second received signal with a second threshold value.
  • the processing is for example carried out in a learning mode activated in the receiver.
  • This learning mode is for example activated in the receiver for a determined period of time after powering up the receiver.
  • the first signal is emitted by the transmitter at a first distance from the receiver and the second signal is emitted by the transmitter at a second distance from the receiver, the second distance being different from the first distance.
  • the first distance is for example greater than the second distance and when decoupling between the transmitter and the receiver, the first distance is for example less than the second distance.
  • the second signal is for example emitted several times in succession to indicate to the receiver a rank to be given to the transmitter in the receiver.
  • the newly registered transmitter may be associated with a particular output of the receiver if the latter has several outputs.
  • the transmissions of the first signal and the second signal are carried out using a button of the transmitter.
  • the transmission of the first signal can for example be performed when the button is pressed and the second signal can be transmitted when the button is released.
  • the button is thus kept pressed when moving the transmitter from the first distance to the second distance.
  • the receiver can carry out a particular treatment consisting of detecting the evolution of the amplitude between the emission of the first signal and the emission of the second signal, and depending on whether this is a sufficient increase or decrease in amplitude, to record or delete the identification code of the transmitter in the receiver.
  • the method comprises a display step on the receiver to indicate whether it is a coupling or a decoupling between the transmitter and the receiver.
  • the visualization step is for example carried out using a light-emitting diode capable of blinking at a variable frequency to indicate the coupling or decoupling between the transmitter and the receiver.
  • the invention also relates to a receiver that can be used in the method described above and able to communicate wirelessly with a transmitter, said receiver comprising: storage means for storing an identification code corresponding to the transmitter, processing means capable of performing an amplitude processing of a first signal sent by the transmitter and a second signal sent by the same transmitter and able to record in the memory means the identification code of the transmitter. transmitter or remove from its storage means the identification code corresponding to the transmitter according to the processing performed.
  • the processing means are capable of performing an amplitude comparison of the first signal or the second signal received by the receiver with a first threshold value.
  • the processing means are able to perform a comparison of an amplitude variation between the first signal and the second signal received with a second threshold value.
  • the processing means are able to detect the evolution of the amplitude between the first signal and the second signal.
  • the receiver is provided with a learning mode in which the recording or deletion of a transmitter is performed.
  • This learning mode is for example activated in the receiver for a determined period of time after powering up the receiver.
  • the second signal is for example emitted several times in succession to indicate to the receiver a rank to confer on the transmitter.
  • the receiver comprises for example a light emitting diode able to flash at a variable frequency to indicate a recording or a deletion of the transmitter.
  • FIG. 1 represents an emitter such as for example a push button able to communicate by wireless link with a receiver controlling one or more outputs
  • FIGS. 2A and 2B illustrate the method of coupling between a transmitter and the receiver
  • FIGS. 3B illustrate the decoupling process between a transmitter and its receiver
  • FIGS. 4A and 4B illustrate implementation variants of the coupling / decoupling between the transmitter and the receiver.
  • FIGS. 1 to 4B each transmitter 1 is for example a wireless pushbutton able to communicate with the receiver 2 through the wireless link.
  • the wireless push button may in particular be of the autonomous type, that is to say without battery, operating using a power converter of electromagnetic type, piezoelectric, photovoltaic ...
  • a power converter of electromagnetic type piezoelectric, photovoltaic ...
  • Other types Transmitters can be envisaged, for example position switch type sensors.
  • the wireless link can be of the radio type (including RFID), infrared, optical ... To simplify the writing, reference will be made in the following description to a transmitter 1 push button and a radio link.
  • An emitter 1 therefore comprises a button 11 which, when pressed, makes it possible to generate a radio signal consisting of one or more identical frequency-specific frames identifying the emitter in a certain way.
  • the receiver 2 comprises means for receiving signals from each transmitter, processing means 21, such as a microprocessor, for processing and interpreting each received signal and storage means 22 in which is stored a list 220 of the data codes.
  • the receiver 2 consists for example of a housing 23 enclosing an electronic card on which are mounted the processing means 21 and the storage means 22.
  • the receiver 2 comprises for example on the front of its housing viewing means, such as for example a light-emitting diode 24.
  • the receiver 2 is intended to control one or more outputs and can therefore be coupled to one or more transmitters 1 depending on the type and the number of outputs 20 it ordered.
  • the outputs 20 may be for example one or more lamps, a garage door, ...
  • the receiver 2 In order to be able to control each of its outputs 20 appropriately, the receiver 2 must then know all transmitters 1 associated with each of its outputs.
  • the receiver 2 must thus be placed in a learning mode in which it is able to record each new transmitter 1 in its list 220 or to delete a transmitter 1 from its list 220.
  • the learning mode can for example be activated automatically for a duration determined after each power-up of the receiver 2. Alternatively, the learning mode can be activated voluntarily by the user by switching the receiver 1 to this mode, for example by manipulation of a button accessible on the housing 23 of the receiver 2.
  • the coupling between the receiver 2 and a new transmitter 1 is performed as follows: first activation of the new transmitter 1, by pressing and releasing the button 1 1 at a distance D1 of the receiver 2 (FIG. 2A), approaching the transmitter 1 with respect to the receiver 2 and second activating the same transmitter 1, by pressing and releasing its button 1 1, at a distance D2 from the receiver 2, the distance D2 being less than the distance D1 ( Figure 2B).
  • the two received signals 30, 31 thanks to the receiving means of the receiver 2 are processed by the processing means 21 of the receiver 2. Since both activations are made from the same transmitter 1, the receiver 2 receives two identical data signals. However, because of the variation of activation distance of the transmitter with respect to the receiver 2, the two signals 30, 31 received by the receiver 2 are different in amplitude as shown in FIGS. 2A and 2B.
  • the recording of the new transmitter 1 by the processing means 21 is validated by comparing the signals with at least two stored threshold values (S1, S2) defined as follows:
  • the amplitude of the signal 31 when the transmitter 1 is at the distance D2 must be greater than a first threshold value S1
  • the difference between the distance D1 and the distance D2 must be sufficient for the amplitude variation between the signal received from the distance D1 and the signal received from the distance D2, for example defined by the ratio between the amplitude at the distance D1 and the amplitude at the distance D2 is less than a second determined threshold value S2.
  • the distance D2 must be chosen very small so that the signal received by the receiver of the distance D2 has a much greater amplitude than that of the signal received when the transmitter is activated at the distance D1.
  • the receiver 2 must register in the list 220 of its storage means 22 an identification code (C1, C2, Cn) corresponding to the signal of the new registered transmitter 1. Once the recording is completed, the light-emitting diode 24 flashes, for example more and more rapidly to give an impression of approaching the transmitter 1.
  • the receiver 2 if the receiver 2 has only one output 20, the coupling is terminated.
  • the transmitter 1 if the receiver 2 has several outputs 20, as shown in FIG. 1, the transmitter 1 must be associated with a determined output. For this, after the second activation of the transmitter at the distance D2, it suffices to press the button 1 1 of the transmitter a number of times corresponding to the rank of the output to which the transmitter 1 must be associated.
  • the rank assigned to the new transmitter is recorded in the storage means 22 of the receiver and associated with the identification code of this transmitter in the list 220.
  • the inverse manipulation of that described above is carried out.
  • the decoupling is also performed when the receiver 2 is in the learning mode defined above and therefore consists in: activating a first time the transmitter 1 to be removed, by pressing and releasing the button 1 1, at a distance D1 from the receiver 2 (FIG. 3A), moving the same transmitter 1 away from the receiver 2 and activating it a second time, by pressing and releasing the button 1 1, at a distance D2 from the receiver 2, the distance D2 being greater than the distance D1 (FIG. 3B ).
  • the decoupling manipulation therefore consists in moving the transmitter 1 away from the receiver 2.
  • the processing of the two signals is similar to that described above. To validate the deletion of a transmitter 1 in the list of the receiver 2 it is therefore necessary that:
  • the amplitude of the signal received by the receiver 2 when the transmitter 1 is at the distance D1 is greater than a first threshold value S3
  • the difference between the distance D1 and the distance D2 is sufficient for the amplitude variation between the signal received from the distance D1 and the signal received from the distance D2, for example defined by the ratio between the amplitude of the transmitted signal the distance D1 and the amplitude of the transmitted signal of the distance D2, is greater than a second determined threshold value S4.
  • the distance D1 is chosen very small so that the signal received from this distance D1 has a much greater amplitude than that of the signal received when the transmitter 1 is activated at the distance D2.
  • the identification code of the transmitter 1 corresponding to the signals 32, 33 received by the receiver 2 is deleted from the list 220 stored in the storage means 22. Once the erasure is effected , the light-emitting diode 24 flashes, for example more and more slowly to give an impression of distance from the transmitter 1.
  • the processing means 21 of the receiver 2 can thus comprise simple amplitude level detection means of the received signals to compare them with the values of stored thresholds.
  • FIGS. 4A and 4B it is possible to use a property of a wireless button which consists in being able to send one or more frames when the button is pressed and also one or more frames. when releasing the button.
  • the user presses the button 1 1 at the distance D1, which causes the emission of one or more frames, and keeps the button pressed while moving up to be at the distance D2 where the user releases the button 1 1 which again causes the transmission of the frames.
  • the processing can then be carried out as previously described according to whether it is a coupling or a decoupling or in another configuration can consist of following the evolution of the amplitude of the signal between the emission of the first signal and transmitting the second signal as the transmitter moves relative to the receiver.
  • the receiver detects a sufficient increase in amplitude, it will register the transmitter or if it detects a sufficient decrease in amplitude, it will proceed to the deletion of the corresponding transmitter.
  • increment or sufficient decrease means an increase or a decrease greater than a determined threshold value.
