Abstract

The invention discloses a train electric-air converting method and device. The train electric-air converting method comprises the steps that electric-air converting speed points of a train under a current running state are obtained; and an electric-air converting instruction is generated according to the electric-air converting speed points, wherein the electric-air converting instruction is usedfor controlling the train to be converted into an air braking state from an electric braking state. The train electric-air converting method and device solves the technical problem of low efficiency in the vehicle braking process due to the fact that the electric-air converting speed points are fixed in the related technology.

Description

technical field [0001] The invention relates to the field of train control, in particular to a train electro-pneumatic conversion method and device. Background technique [0002] At present, when the vehicle stops at a low speed (below 8km / h), due to the limitation of electric braking capability, it will look for a fixed speed point as the transition point between electric braking and air braking. Both braking and airbraking are exited or entered with a certain exit ramp. However, due to the fixed conversion point of this conversion method, the end point of electric braking is different under different braking levels, and the electric braking capacity is not fully utilized and the braking characteristics of the vehicle during the braking process inconsistencies. [0003] Aiming at the problem of low efficiency in the vehicle braking process caused by the fixed electro-pneumatic conversion speed point in the above-mentioned related technologies, no effective solution has be...
