Abstract

Repetidor de mensagens embarcado para um sistema de comunicações de um trem ferroviário. Um sistema de comunicação para um trem (10) de tração distribuída, para enviar e para receber sinais entre a locomotiva líder (14) e as locomotivas remotas (12A /12B/12C) no trem (10). Uma mensagem iniciada na locomotiva líder (14) é recebida por ao menos uma locomotiva remota (12A / 12B) próxima a locomotiva líder (14). A unidade remota que recebe (12A / 12B) retransmite a mensagem para ser recebida pela unidade remota seguinte (12C) no trem. Assim, amensagem salta em direção ao final do trem, no sentido da locomotiva líder (14) para as unidades remotas (12A / 12B /12C). Quando a última unidade remota (12C) recebe a mensagem, a última unidade remota (12C) transmite uma mensagem de situação, ou outra resposta, para a mensagem da unidade líder. A mensagem de situação é recebida pela unidade remota n-1 (12A / 12B), a qual a qual anexa a sua mensagem e situação e transmite a mensagem de situação combinada em sentido da unidade líder (14). Cada unidade remota sucessiva recebe as mensagens de situação das outras unidades remotas e anexa a sua mensagem de situação, até que a mensagem de situação concatenada alcance a unidade líder (14).
