Abstract

The method involves placing a group of receivers in storage mode for allowing the acquisition of a new identifier of a new wireless control. The new control is actuated for emitting the new identifier. The new identifier is stored by each receiver in the group while conserving a preceding identifier in an additional memory. The new identifier stored in the receiver is erased and the preceding identifier is conserved when the new identifier received by the receiver corresponds to the preceding identifier.

Description

The invention relates to a method for replacing a wireless control operating a receiver in an installation comprising a plurality of receivers.

The use of electric motorized shutters is becoming more and more widespread.

These installations consist of several shutters each being controlled by a wireless command recognized only by the component considered. The wireless control includes a transmitter often wireless and the electronics of the shutter motor a receiver.

For this the receiver is associated with a transmitter and for this it was previously stored an identifier. When the wireless command sends an order to move the deck; it is accompanied by the identifier.

Sometimes the remote control is destroyed and must be replaced.

The process of recognition of the remote control by the shutter is often to place the electronics contained in the shutter in a particular mode called recording to memorize the identifier of the transmitter that one activates. To place the receiver in this particular mode, it often starts with an action that consists in acting on the flap either by means of a button that equips the shutter receiver and which places the said shutter receiver in the acquisition mode of the shutter. the identifier is by acting on the supply of the shutter, for example by cutting and resetting the current at close intervals at a defined rate.

The first solution is not difficult except for access to the button.

For the second solution, there is no difficulty when we can cut the power of the flap considered independently of other components because in this case we activate a single flap. However, more and more often, during the installation, several shutters are connected to the same circuit breaker / switch so that when we proceed to the operation of breaking the current via this circuit breaker is placed all the shutters of the group powered by this circuit breaker in acquisition mode of the identifier. The consequence is that all the parts change identifier.

A solution to this problem is known. It consists in temporarily limiting the power of the transmitter of the remote control in order to force the speaker to approach the flap in question so that it and only this one receives the signal. Then reset the remote control to normal mode.

The invention aims to propose a simpler and more effective solution.

For this purpose, the object of the invention is a method for replacing a wireless control recognized by a single receiver of a group of receivers, said receiver recognizing the wireless control assigned to it by means of an identifier. stored according to which method by a maneuver of cutoff on the power supply of the group of receivers and a restoration of the supply is placed all the receivers of said group in mode allowing the acquisition of a new identifier of a new order This process is characterized in that, when the new so-called catch-up command is actuated to transmit the new identifier, each receiver of said group stores the new identifier while keeping in an auxiliary memory the old identifier and when a receiver receives a show with identifying the old identifier, it deletes the new identifier.

• FIG 1 : Ordinogramme du procédé selon l'invention
• FIG2 : Vue schématique d'une installation.

The invention will be better understood from the following description given by way of non-limiting example with reference to the drawing which represents:

• FIG 1 : Flow chart of the process according to the invention
• FIG2 : Schematic view of an installation.

Referring to the drawing, there is shown a group of flaps V V2, V3 electrically powered by a circuit 100 comprising upstream means 101 for breaking for example type circuit breaker or fuse.

Each shutter is motorized and each electric motor includes electronics with its receiver associated with a single transmitter of a wireless control. The receiver has memorized an identifier ID1, ID2, ID3 that the transmitter El, E3 sends with an order (up or down) to move the apron of the shutter. The remote only has a transmitter and does not necessarily have a receiver, so it is one-way but it would work with a two-way remote.

So there are as many remote controls as there are shutters. Sometimes there is a remote control that can control all the shutters at once or each individually. When a remote control malfunctions, it may need to be replaced.

A method for replacing a wireless control recognized by a single receiver of a group of receivers is then implemented by the receiver recognizing the wireless control assigned to it by means of a stored identifier according to which method by a maneuver to cut off the power supply of the group of receivers and restoration of the current, all of the said group receivers are placed in a mode allowing the recording of a new identifier of a new wireless E100 replacement command .

That is to say, the power cut according to possibly a certain rhythm will put into operation a subroutine called storage of an identifier.

An order (up or down) is then sent with the new remote control E100 called "catch-up", this order being accompanied by a new identifier ID 100. Each receiver of said group stores the new identifier while keeping in an auxiliary memory the old identifier ( Idl, ID2, ID3) and when a receiver receives a broadcast with for identifying the old identifier, it removes the new identifier and keeps the old one. Thus, with the exception of the shutter which has been allocated the new remote control called catch-up, the other receivers of the group will at any given time each receive an order from the remote control that had been previously assigned containing the identifier. The program in the receiver will then compare the identifier it receives with the new identifier it has just memorized and the old identifier it has retained. By noting that the received identifier corresponds to the old identifier, the receiver will erase the new identifier and keep only the old identifier.

Thus, only one of the set of receivers will never receive the old identifier.

For security, when the receiver to which the new wireless command has been assigned and therefore the new identifier has been requested with the new identifier a minimum of times, the old identifier is deleted.

To secure the process, the replacement remote control transmits not only the new identifier but also an instruction code indicating to the receivers that one is in a particular configuration of replacement of a remote control and thus activating the recording mode. particular. This remote will be provided after verification by the seller that the buyer is legitimate.

This avoids that during a breakage of fortuitous current, the process is triggered with one of the other remote controls.

Thus, when the power is restored, the new remote control E100 called catch-up will emit a code indicating to all receivers to put in recording mode of a replacement remote control that confirms the action on the power supply. There will thus be jointly, a cut and restore the current then send a confirmation code exceptional recording mode of a catch-up command.

The means implemented therefore comprise on the receiver means for managing a first identifier and a second new identifier from a new remote control.
