Abstract

Viene descritto un telecomando (1) nel quale il codice di riconoscimento trasmesso dal trasmettitore è composto da una parte fissa (codice di identificazione, A) e da una parte memorizzante il numero di azionamenti (codice azionamenti B). Il codice azionamenti è generato da un contatore (7) disposto nel trasmettitore (2) e viene incrementato ad ogni azionamento del telecomando. Tale codice viene inoltre scritto nel ricevitore (3) al termine di ogni azionamento andato a buon fine. Al ricevimento del codice di riconoscimento, il ricevitore (3) verifica l'uguaglianza del codice di identificazione ricevuto con il codice di identificazione memorizzato e verifica che il codice azionamenti ricevuto sia maggiore di almeno una unità rispetto al codice azionamenti precedentemente memorizzato nella propria memoria (29). Il segnale di consenso per gli attuatori viene generato solo se la verifica da esito positivo. In tal modo, l'eventuale copiatura del codice non consente l'effrazione, purché il ricevitore (3) venga azionato almeno una volta nel periodo di tempo fra la copiatura del codice e l'uso del codice copiato.Figure 1, 2.
