Problems solved by technology

In the prior art, various calculation models are used to match the electric braking force exit point and the air braking force replenishment point in order to improve the matching accuracy of the above two, but this method also brings extremely high computational complexity. Calculation delay
At the same time, the electropneumatic braking method requires multiple subsystems in the train to cooperate with each other, and the signal / data transmission between multiple subsystems will cause transmission delay
[0004] However, in all the current methods of optimizing electro-pneumatic brake coordination, it is impossible to prove that the method itself has nothing to do with time delay
Therefore, both the calculation delay and the transmission delay will react on the calculation model itself, and the expected effect of improving the good matching between the electric braking force exit point and the air braking force supplement point cannot be achieved, so that it is impossible to fundamentally solve the problem of under-standard or Stamping problem

Abstract

The invention provides a train braking method and device, a storage medium and electronic equipment, and relates to the technical field of train network control. The method comprises the steps that when a braking instruction is received, calculating an electric braking force needed by a train; acquiring a current available DCU in the train; distributing the electric braking force needed by the train to the current available DCU according to a preset algorithm, and obtaining the electric braking force needing to be executed by each DCU; and sending the electric braking force needing to be executed by each DCU to the corresponding DCU, so that each DCU executes electric braking according to the corresponding electric braking force needing to be executed until the train speed is zero. According to the method provided by the invention, the accuracy of braking and parking of the train can be improved, so that the occurrence frequency of mark lacking or mark rushing of the train is reduced.

Description

technical field [0001] The invention relates to the technical field of train network control, in particular to a train braking method, device, storage medium and electronic equipment. Background technique [0002] The existing train braking mainly adopts the method of combining electric braking and air braking, that is, during the train braking process, the electric braking is first applied until the train decelerates to a lower speed, and the electric braking exits, and at the same time Apply the air brakes until the train decelerates to zero. [0003] The existing electro-pneumatic braking method makes the accuracy of the train braking and parking insufficient, and it is easy to cause the train to be under-marked or over-marked, that is, the distance between the center line of the train door and the center line of the screen door at the train parking place is less than or greater than 30cm, which may cause the screen door to fail. Action, passengers can not get on and off...
