Problems solved by technology

[0005] The embodiments of the present invention provide a train speed control method and device, which are used to solve the defect that the unbreakable speed of the train in the prior art cannot meet the maximum allowable collision speed of the coupler of the target train when the train is running, so as to shorten the speed of the target train. The gap between the running speed and the unbreakable speed meets the requirements of the maximum allowable collision speed of the coupler

Abstract

The embodiment of the present invention provides a train speed control method and device. When the target train is connected to the collided train, the traction cutting method is adopted to cut off the traction of the target train in advance, and the emergency braking of the target train can be triggered before the traction is cut off. The protection speed of the curve is increased to a speed close to the emergency braking curve, thereby increasing the controllable range of ATO control speed, which can shorten the gap between the running speed of the target train and the unbreakable speed, so as to meet the maximum allowable collision speed of the coupler. .

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a train speed control method and device. Background technique [0002] For multi-section trains, train coupling refers to colliding the coupler of the target train with the coupler of the collided train to achieve coupling, and short-distance parking of the train refers to the short-distance parking of the front car to the collidable rear car. In front of the car. This all needs to control the speed of the target train or the vehicle in front. [0003] According to the current mature technology, the allowable repeated collision speed of the train coupler is not higher than 5km / h, that is, the maximum allowable collision speed of the train coupler is 5km / h, and the reliable speed of the coupling needs to be guaranteed to be 2-5km / h. Calculated according to the safe braking model of IEEE 1474.1, when the train running speed is 2-5km / h, its unbreakable speed is above 10...
