Abstract

The invention discloses a train speed limiting control method and device. The train speed limiting control method comprises the steps of detecting whether an instability phenomenon occurs or not during the running of a train; when it is detected that the instability phenomenon occurs during the running of the train, applying braking to the train; and limiting the speed of the train to enable the train to run at a first speed. Through technical scheme, automatic speed limiting control in the train running process is realized, the technical scheme is applied to the train running control so thatthe labor intensity of a driver can be reduced; when the instability phenomenon occurs during the running of the train and the speed limiting control is carried out on the train in time, the fact thatthe train running safety is affected due to negligence of a driver is effectively avoided.

Description

technical field [0001] The present application relates to the technical field of train automatic control, in particular to a train speed limit control method and device. Background technique [0002] With the continuous development of my country's high-speed train business, the number and operating speed of high-speed trains continue to increase, and ensuring the smooth and safe operation of trains has become the key to ensuring the normal operation of high-speed train systems. [0003] There will be various changes in the condition of the line on which the train travels, coupled with the influence of natural weather on the train, the train may be unstable during operation. When a train loses stability, an early warning of the instability should be given in time, and the speed limit of the train should be implemented in time, so as to ensure the safety of the train. Usually rely on the driver to implement appropriate speed limit for the instability phenomenon of the train a...
