CA 2193846

A rolling code transmitter is useful in a security system for providing secure encrypted RF transmission comprising an interleaved trinary bit fixed code and rolling code. A receiver (202) demodulates the encrypted RF transmission and recovers the fixed code and rolling code. Upon comparison of the fixed and rolling codes with stored codes (220) and determining that the signal has emanated from an authorized transmitter, a signal is generated to actuate an electric motor (234) to open or close a movable barrier.

L'invention concerne un émetteur-récepteur à code de brassage utilisé dans un système de sécurité pour assurer une transmission HF codée en toute sécurité, à l'aide d'un code fixe à bits trinaires entrelacés et d'un code de brassage. Un récepteur (202) démodule la transmission HF codée, et récupère le code fixe et le code de brassage. Lors de la comparaison des codes fixes et de brassage, avec des codes mémorisés (220), et lors de la détermination de la provenance du signal d'un émetteur-récepteur autorisé, un signal est généré pour actionner un moteur électrique (234) pour ouvrir ou fermer une barrière mobile.
