Abstract

Viene descritto un telecomando (1) nel quale il codice di riconoscimento è composto da una parte fissa (codice di identificazione, A) e da una parte variante nel tempo (codice temporale B). Il codice temporale viene generato contemporaneamente da un contatore (7) disposto nel trasmettitore (2) e da un contatore (30) disposto nel ricevitore (3). I due contatori vengono sincronizzati fra loro in fase di personalizzazione del telecomando e al termine di ogni attuazione del telecomando. Il codice di riconoscimento trasmesso in ogni istante è quindi legato all'istante in cui viene effettuata la trasmissione del codice e varia nel tempo, impedendo le effrazioni dovute alla copiatura del codice di riconoscimento in un certo istante.Figure 1, 2.A remote control (1) is described in which the recognition code is composed of a fixed part (identification code, A) and a part that changes over time (time code B). The time code is generated simultaneously by a counter (7) arranged in the transmitter (2) and by a counter (30) arranged in the receiver (3). The two counters are synchronized with each other during the remote control customization phase and at the end of each remote control actuation. The recognition code transmitted at any time is therefore linked to the instant in which the transmission of the code is carried out and varies over time, preventing break-ins due to the copying of the recognition code in a certain instant. Figures 1, 2.
