Abstract
um sistema de controle de ciclo de purga para um sistema de frenagem de locomotiva, compreendendo: uma secadora de ar de torres duplas (12) possuindo primeira e segunda torres a serem posicionadas entre um primeiro reservatório principal (mr1) e um segundo reservatório principal (mr2) do sistema de frenagem de locomotiva e sendo configurado para comutar o fluxo de ar através de uma das primeira e segunda torres para a outra das primeira e segunda torres em resposta a um comando de controle de purga; e um sistema de frenagem controlado por computador (22) a ser acoplado ao sistema de frenagem de locomotiva e à secadora de ar por uma linha de controle de purga (40), onde o sistema de frenagem controlado por computador é programado para enviar o comando de controle de purga para a secadora de ar quando o fluxo de ar através da secadora de ar excedeu um limite predeterminado. o sistema maximiza o uso de cada torre em vez da comutação de acordo com um período de tempo predeterminado.a purge cycle control system for a locomotive braking system, comprising: a double towers air dryer (12) having first and second towers to be positioned between a first main reservoir (mr1) and a second main reservoir ( mr2) from the locomotive braking system and being configured to switch air flow through one of the first and second towers to the other of the first and second towers in response to a purge control command; and a computer controlled braking system (22) to be coupled to the locomotive braking system and air dryer by a purge control line (40), where the computer controlled braking system is programmed to send the command. control parameters for the air dryer when the air flow through the air dryer has exceeded a predetermined limit. The system maximizes the use of each tower rather than switching over a predetermined period of time.
