Abstract

Per rilevare la condizione di occupazione di un tratto di binario (B) nell'associato circuito di binario vengono generati messaggi digitali di tipo seriale con una parola formata ad esempio da 4 bit in sequenza, pseudocasuale che determinano l'emissione di corrispondenti frequenze che si succedono in modo pseudocasuale.(Figura 1)To detect the occupation condition of a section of track (B) in the associated track circuit, serial digital messages are generated with a word formed for example by 4 bits in sequence, pseudorandom which determine the emission of corresponding frequencies that they happen in a pseudorandom way. (Figure 1)
