Problems solved by technology

However, when the wind speed is variable and changes rapidly, it is not only necessary to control the frequent train speed changes, which increases safety hazards, but also reduces the operating efficiency of the high-speed rail, which is likely to cause train delays and waste energy.
In addition, in the existing schemes, the wind speed at the actual arrival position of the train is used as the speed adjustment condition, which makes it difficult for the staff on the train to respond in time, and it is difficult to make macro-control on a certain railway line, making the railway Travel safety is threatened

Description

technical field [0001] The embodiments of the present invention relate to the field of railway operation safety, in particular to a method, device, storage medium and high-speed train for controlling the running speed of a high-speed train. Background technique [0002] my country's high-speed rail was officially put into operation in 2008, and in 2016 it has become the country with the longest high-speed rail operating mileage in the world. The emergence of high-speed rail has greatly improved people's travel efficiency. During driving, the wind speed is one of the main factors affecting the speed of the vehicle, that is, when the wind speed reaches a certain threshold, the vehicle speed should be reduced to ensure driving safety; when the wind speed drops to a certain threshold, the vehicle speed should be restored to improve driving speed. efficiency. However, when the wind speed is variable and changes rapidly, it not only needs to control the train to change frequently...
