Abstract

A transmitter is adapted to transmit a command, toward one or more receivers. Each receiver is adapted to receive said command and identify said transmitter, which as transmitted it. Furthermore, each receiver is adapted to supply a signal addressed to an installer, for example, a visual signal, by actuating an operator connected to the receiver. The method for matching a transmitter and a receiver includes assigning a subset or a rank to each receiver; then the receivers supply a signal, depending on their subset or their rank, for example, in response to a rank modifying command. When only the receiver to be matched supplies a signal, the installer emits a command from the transmitter. The receiver, which has just supplied the signal, receives the command and is matched to the transmitter, which has transmitted it the matching is carried out without any action on the receivers, simply by means of commands transmitted from the transmitter.

Claims

1. A method for pairing a transmitter and one of at least two receivers, the transmitter being adapted for sending a command, each receiver being adapted to receive this command and to identify the transmitter and to supply a signal intended for an installer, the method comprising:

(a) defining a subset from among the set of receivers;

(b) supplying the signal by each receiver of the subset; and

(c) if only the receiver to be paired has supplied the signal, a step of transmitting a command by the transmitter and pairing the receiver having supplied the signal with the transmitter which transmitted the command and, if not, defining a new subset, the step of defining a new subset being followed by an iteration of steps (b) and (c).

2. The method of claim 1, wherein the step of defining the new subset comprises defining a new subset of cardinality less than the preceding one.

3. The method of claim 1, wherein the step of defining the new subset comprises

defining a new subset included in the preceding subset if the receiver to be paired has supplied the signal;

and

defining a new subset disjoint from the preceding subset if the receiver to be paired has not supplied the signal.

4. The method of claim 2, wherein the step of defining a new subset comprises

defining a new subset included in the preceding subset if the receiver to be paired has supplied the signal;

and

defining a new subset disjoint from the preceding subset if the receiver to be paired has not supplied the signal.

5. The method of claim 1, wherein the receivers are represented by leaves of a tree.

6. The method of claim 2, wherein the receivers are represented by leaves of a tree.

7. The method of claim 5, wherein the steps (a), (b) and (c) are carried out according to a dichotomic traversal of the tree.

8. The method of claim 6, wherein the steps (a), (b) and (c) are carried out according to a dichotomic traversal of the tree.

9. The method of claim 1, further including assigning each receiver with a rank, wherein defining a subset comprises the choice of a receiver of a given rank, and wherein defining a new subset comprises the choice of a receiver of another rank.

10. The method of claim 9, wherein the assigning step comprises, for each receiver, the choice of an order number independently of the other receivers.

11. The method of claim 9, wherein the choice is random.

12. The method of claim 9, wherein the receivers can communicate, and wherein the assigning step comprises assigning of a separate number to each receiver.

13. The method of claim 12, wherein the separate numbers are consecutive.

14. The method of claim 9, wherein the step of changing of rank comprises the transmission by the transmitter of a change of rank command.

15. The method of claim 9, wherein the transmitter comprises a unique identification number sent in a command, and wherein the pairing step comprises the storage by the receiver of the number contained in the command.

16. A method of pairing for a receiver adapted to receive a command send by a transmitter and to identify the transmitter and to supply a signal intended for an installer, the method comprising:

(a) assigning a rank;

(b) supplying the signal as a function of this rank; and

(c) on receipt of a command following the supplying step, pairing with the transmitter which sent the command.

17. The method of claim 16, wherein the assigning step comprises the choice of an order number.

18. The method of claim 17, wherein the choice is random.

19. The method of claim 16, wherein the receiver can communicate with other receivers, and wherein the assigning step comprises communicating to other receivers and the possible receiving of responses from the other transmitters.

20. The method of claim 16, wherein the step of supplying the signal comprises receiving of at least one change of rank command and the supplying of the signal as a function of the number of change of rank commands received.

21. The method of claim 16, wherein the command sent by a transmitter comprises a unique identification number and wherein the pairing step comprises the storage of the number contained in the command.

22. A receiver having:

a circuit for receiving and for decoding commands sent by a transmitter;

means for supplying a signal intended for an installer;

a program executing a method of pairing for a receiver adapted to receive a command send by a transmitter and to identify the transmitter and to supply a signal intended for an installer, the method comprising;

(a) assigning a rank;

(b) supplying the signal as a function of this rank; and

(c) on receipt of a command following the supplying step, pairing with the transmitter which sent the command.

23. The receiver of claim 22, wherein the receiver comprises a storage memory.

24. The receiver of claim 22, wherein the circuit is also adapted for transmitting.
