Abstract

é descrito um sistema de detecção de trilhos interrompidos, incluindo um módulo de potência tendo: uma primeira conexão elétrica com o primeiro trilho, para aplicar uma tensão de corrente contínua; e uma segunda conexão elétrica com o segundo trilho, para aplicar uma tensão de corrente contínua; um arranjo de diodo ponte (shunt); um dispositivo de medição para detectar ou medir corrente; e um controlador programado ou configurado para: (i) provocar pelo menos uma aplicação de uma tensão de corrente contínua de uma primeira polaridade na via férrea; (ii) determinar a corrente resultante da etapa de aplicação (i); (iii) provocar pelo menos uma aplicação de uma tensão de corrente contínua de uma segunda polaridade na via férrea; (iv) determinar a corrente resultante da etapa de aplicação (iii); e (v) determinar a presença ou ausência de uma interrupção, com base, pelo menos parcialmente, na corrente determinada.
