The invention discloses a
train control grade
transition system and method thereof in the technical field of
train control. The method includes the steps that 1, a CTCS-2
station train control centeridentifies the state of a polarized
relay in a semi-automatic blocking change direction logic circuit, and the CTCS-2
station pickup and departure states are formed; and 2, during CTCS-2
station departure, a train speed monitoring curve is modified by adding and modifying reverse operation message parameters; during CTCS-2 station lateral
pickup, a speed limiting point is set at a grade transitionpoint to modify the train speed monitoring curve, a train passes through the boundary of a CTCS-2 station and a CTCS-0 station according to speed limiting of the train speed monitoring curve, and meanwhile, a train on-board device completes switching of a CTCS-2
system and a CTCS-0
system. The train control grade
transition system and method thereof has the beneficial effects that in case of maintaining semi-automatic blocking of the existing two stations, an interval trackless circuit, no additional renovation work of the CTCS-0 station, non-stopping switching of the train between the CTCS-0train
control system and the CTCS-2 train
control system is achieved, speed transition during switching is stable, and the efficiency of train transportation is improved.
