Abstract

"SISTEMA DE FRENAGEM DE FERROVIA PARA UM TREM, E, PROCESSO PARA A DETECçãO DE RECEPçãO DE UM SINAL DE CONTROLE PNEUMáTICO PROPAGADO AO LONGO DE UM TUBO DE FRENAGEM" Um sistema de frenagem de ferrovia (10) para um trem inclui um tubo de frenagem que se estende ao longo do trem, um controlador de unidade principal (29) que gera um sinal de controle pneumático propagado ao longo do tubo de frenagem, e pelo menos um controlador de unidade remota (25, 28). O controlador de unidade remota inclui preferivelmente uma válvula de controle de tubo de frenagem, tal como uma válvula relé (26), conectada em comunicação por fluido com o tubo de frenagem (20) para carregar e exaurir seletivamente o tubo de frenagem, um sensor de taxa de fluxo de ar (30, 31) para perceber o fluxo de ar de entrada no tubo de frenagem durante o carregamento, um sensor de pressão de tubo de frenagem (40) para perceber a pressão do tubo de frenagem, e um processador (36) para detectar o sinal de controle pneumático do controlador de unidade principal com base em ambos o sensor de taxa de fluxo de ar e o sensor de pressão de tubo de frenagem. De acordo, a sensibilidade de detecção é aumentada independentemente da operação com retardo da válvula relé, e enquanto evita falsas indicações. Múltiplas sensibilidades de detecção podem ser utilizadas. A detecção pode ser utilizada para cortar o controlador de unidade remota e colocar em marcha lenta a locomotiva, como quando as comunicações de rádio são perdidas. A detecção pode ser utilizada também para testar a continuidade e/ou determinar a posição relativa da unidade remota ao longo do trem.
