A method for protecting coupled trains from
unintended movement. The method comprises: firstly, according to a
train marshalling type and coupler attribute information, determining the length of a coupled operation zone and the maximum
speed limit for
coupling collision of the coupled operation zone, then calculating a safety distance for a coupled protection zone according to
train attributes and the maximum
speed limit for
coupling collision of the coupled operation zone, and finally calculating, according to the safety distance, all possible chains in a
coupling direction from an end point of the coupled operation zone, so as to generate a coupling operation protection chain, wherein a coupling operation process is as follows: according to
train information in a coupling operation request, a coupled operation zone and a protection chain state, a zone controller ZC setting a restriction state for a coupling operation protection chain and initiating a coupling locking request to an
interlocking system (S1); once it is confirmed that no train movement
authorization accesses the coupled protection zone and no coupling locking occurs therein, the zone controller ZC authorizing a coupling operation (S2); and after the coupling operation is finished, cancelling coupling protection restrictions and the coupling locking request (S3), such that the
impact range of coupling protection can be optimized, the protection of coupled trains in abnormal scenarios can be enhanced, and safe and efficient coupling operations can be ensured. Further provided are an electronic device for protecting coupled trains from
unintended movement, and a computer-readable storage medium.
