Abstract: Изобретение относится к диагностике тягового подвижного состава железных дорог и направлено на повышение безопасности движения поездов. Способ заключается в следующем. При включении мотор-компрессора измеряют время повышения давления в питательной магистрали на 0,05 МПа, затем после его выключения и последующего снижения давления в питательной магистрали на 0,05 МПа измеряют плотность тормозной магистрали по времени снижения давления в питательной магистрали. Результаты измерения плотности, полученные после первых измерений с момента начала измерения после понижения давления в ПМ на 0,05 МПа, регистрируются как минимальная плотность. Результаты измерения плотности, полученные в последний замер перед включением мотор-компрессора, регистрируются как максимальная плотность. По команде машиниста фиксируют значение параметра плотности одиночного локомотива. При этом в памяти сохраняется максимальная и минимальная плотности локомотива. После зарядки тормозной магистрали и готовности системы к фиксированию плотности регистрируют плотность тормозной магистрали поезда и рассчитывают разницу времени снижения давления в питательной магистрали на 0,05 МПа одиночного локомотива и аналогичного снижения давления с поездом. При этом учитывают величину давления в питательной магистрали локомотива в момент определения и регистрации плотности поезда и определяют максимальную и минимальную плотности поезда, после чего исходя из соотношения плотностей локомотива и поезда определяют и регистрируют максимальную условную плотность состава вагонов. Далее включают режим торможения длительностью 1 с и вычисляют изменение плотности поезда с целью определения количества вагонов в составе, сработавших на торможение. После срабатывания автотормозов начинают отсчет времени. По достижении перепада давления 0,05 МПа при неработающем мотор-компрессоре регистрируют время понижения давления и производят вычисление длины тормозной магистрали. После регистрации плотности поезда производят ее непрерывный контроль. Сравнивают текущие показания плотности поезда с зарегистрированными показаниями плотности поезда и состава вагонов. При этом каждый раз определяют фактическую плотность поезда и состава вагонов и вычисляют максимальную и минимальную плотности поезда и состава вагонов. При повышенном расходе сжатого воздуха и интенсивном снижении плотности питательной магистрали в течение 10 с и более на монитор МПСУ выводится предупреждающая информация о возможном разрыве тормозной магистрали.
