ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an assembly comprising at least one device remotely controlled by at least one transmitter possessing an identity number and capable of transmitting a signal consisting of a frame containing the identity number and a command, a receiver associated with the remotely Controlled device and capable of extracting the identity number and the command from the signal received, this receiver containing a logic processing unit comprising a memory intended for storing at least one identity number, a processor containing a recording program ensuring, on receiving an identity number, the storing of the identity number received if this identity number is not already recorded and the erasing of this identity number if it is already recorded, this microprocessor being able to work in an operational mode in which it compares the identity number received with the identity numbers contained in the memory so as to execute the command received when the identity number received corresponds to an identity number contained in the memory and in a recording mode in which it is able to ensure the recording of the identity number of the transmitter in the memory, the transmitter and the receiver comprising associated means for placing the processor in recording mode.
The remotely controlled devices are, for example, roller blinds, shutters, lighting means, air conditioning means or the like.
Such an assembly is known from the document FR-A-2 761 183, the content of which is incorporated by reference. This assembly allows the storing of the identity numbers of other transmitters in the memory of a receiver or the reconfiguring of the assembly by means of a transmitter known to the receiver, without intervening directly in the receiver, thereby minimizing the need for access to the receiver. This assembly represents not only a solution to the absence of access to the receiver, but also a considerable time saving.
SUMMARY OF THE INVENTION
In this assembly, a receiver can obey the commands from several transmitters whose identity numbers are registered in its memory. It may however be desired that a transmitter should be able to control one receiver only. To this end, it is necessary to make the receiver understand that it should not accept a command from another transmitter. The present invention is aimed precisely at solving this problem.
The assembly according to the invention is one wherein at least one transmitter of the assembly is a transmitter of the so-called simple type, that is to say a transmitter whose signal frame contains an identifier signifying that this transmitter may control only a single receiver, and wherein the program contained in the processor of at least one receiver contains a routine for testing and for identifying the type of transmitter preventing the recording of additional transmitter identity numbers in the memory if the identity number identified is that of a transmitter of simple type.
Any receiver having recorded the identity number of a transmitter of simple type will therefore not be able to be controlled by another transmitter, whether or not of simple type.
In such an assembly, one may however wish to be able to carry out a general control a posteriori, that is to say to control a receiver via several transmitters. To this end, according to one mode of execution of the invention, the assembly comprises at least one auxiliary remote control box associated with at least one transmitter, this auxiliary box making it possible to transmit a control signal whose reception by the receivers has the effect of deactivating the said routine and consequently of authorizing the recording of additional transmitter identity numbers in the memory in such as a way as to allow the recording of an identity number of a transmitter used as general control transmitter, the program contained in the processor of the receivers containing a routine for testing the reception of a signal emanating from an auxiliary box, deactivating the said routine on receiving such a signal.
The transmitter with which an auxiliary box is associated can be a transmitter of “standard” type or a transmitter of simple type.
In the absence of any deactivation signal, the routine for testing and identifying the type of transmitter is activated.
