ABSTRACT:
The device according to the invention is useful for recognizing binary locking words in a digital train. It comprises six flip flops connected to an AND gate for recognizing the first six bits of the locking words. The first five flip flops are connected to an AND gate for recognizing the last five bits of the locking words. A seventh flip flop makes it possible to confirm and memorize the identification of the first six bits of the locking words and an AND gate, connected between the sixth and the seventh flip flops, ensures erasure of the memorization of the first identification.
