Abstract

L'invenzione consiste in un sistema di telecomando particolarmente adatto per dispostivi antifurto, la cui sezione trasmittente genera un messaggio contenente almeno un codice di identificazione, fisso, ed un codice di controllo, variabile; l'unità logica della sezione ricevente, se riconosce in un messaggio ricevuto il proprio codice di identificazione, verifica la correttezza del relativo codice di controllo prima di disattivare, ad esempio, un impianto antifurto e/o far aprire una porta, eccetera.In un sistema secondo l'invenzione, il codice di controllo è costituito dal numero memorizzato in una coppia di contatori, appartenenti rispettivamente alla sezione trasmittente ed a quella ricevente, che vengono fatti avanzare di un numero prefissato di passi ad ogni attivazione del sistema di telecomando realizzato secondo l'invenzione; sono previsti adeguati accorgimenti logici per ovviare ad eventuali "perdite di passo" dei due contatori (figura 1).The invention consists of a remote control system particularly suitable for anti-theft devices, the transmitting section of which generates a message containing at least one fixed identification code and one variable control code; the logical unit of the receiving section, if it recognizes its own identification code in a received message, checks the correctness of the relative control code before disabling, for example, an anti-theft alarm system and / or opening a door, etc. system according to the invention, the control code consists of the number stored in a pair of counters, belonging respectively to the transmitting and receiving sections, which are advanced by a predetermined number of steps each time the remote control system created according to the invention; adequate logical measures are provided to remedy any "step losses" of the two meters (figure 1).
