Problems solved by technology

However, although the FSB trigger curve determined by the above method can ensure that the EB trigger curve is triggered infrequently, it cannot fully and effectively control the train braking, and cannot guarantee that EB will not be triggered during the process from triggering the FSB trigger curve to the completion of the FSB. Trigger curves, i.e. ATP on-board systems still trigger unnecessary emergency braking in certain situations, so the above method does not follow the design principles very well

Abstract

The invention discloses a braking control method for a train. The driving distance of the train is determined by five stages of a full service braking traction removing stage, a full service braking response establishing stage, an emergency braking traction removing stage, an emergency braking response establishing stage and an emergency braking finishing stage in a sub-stage way, and further the full service braking trigger speed is determined by backward recurrence, the distance between the position where the train is positioned and a speed limit point of a target and the driving speed of a current train are guaranteed, and the condition that emergency braking is trigged when full service braking is triggered is avoided.

Description

[0001] The patent application for the present invention is a divisional application of the invention titled "A braking control method for an automatic train protection vehicle-mounted system". The original application was filed on January 24, 2014, and the application number was 2014100338164. Technical field [0002] The invention relates to the field of train automatic protection vehicle-mounted systems, in particular to a brake control method of train automatic protection vehicle-mounted systems. Background technique [0003] According to the existing ATP (Automatic Train Protection, automatic train protection) on-board technology, an EB (Emergency Brake) trigger curve is derived from the distance between the train and the target speed limit position and the speed of the train. When the speed of the train at a certain position exceeds the point on the EB trigger curve, the on-board system will trigger the emergency brake. Once the emergency brake is triggered, the train will be ...
