Acquire line information. Every section conforms to a track relay electrically. When the forward train enters into
the section, relevant track relay will respond, interlocking
equipment then deal with this information and all kinds of
relay nodes in control equipment room will form “coding
control condition”, and then track circuit will send out
relevant safety information to the latter train.
The function of operation control is centralized on board.
Inductors on latter train successively receive information
delivered by steel tracks. The information includes goal
distance, speed rating, line parameter and so on. The
equipment on the train real-time checks speed and position
of the train. In order to keep safe running distance between
forward train and the latter and avoid collision accidents,
control system on the train deals with the datum collected
from the other parts and forms real-time speed-distance
curve according to certain mathematic model. Permissible
speed limit of the signal system is displaying incessantly in
the driver’s room. Operation control adopts the principle of
“manual control precedence”. The driver controls train based
on running curve while Autom
