Abstract

The invention discloses a train control method, device, equipment and medium, which are used to solve the existing problem of inaccurate calculation when determining the target running speed in the braking and parking process of the train. Since the embodiment of the present invention is based on the first actual speed, the train configuration information and the slope acceleration value corresponding to the road gradient between the starting parking position and the stopping position, the target running speed of the train braking and parking process is comprehensively determined. The target running speed is determined only according to the actual speed of the train at the starting parking position, the train configuration information, etc., which improves the accuracy of determining the target running speed and ensures the safety of the train during braking and parking.

Description

technical field [0001] The present invention relates to the technical field of train control, in particular to a train control method, device, equipment and medium. Background technique [0002] During the process of controlling the braking and stopping of the train, the Automatic Train Operation (ATO) equipment calculates the most suitable braking and stopping target speed of the train based on the safe braking distance curve model, and determines the traction, Measures such as braking or coasting, so as to control the train to brake and stop. [0003] When the current target speed of the braking stop process is calculated based on the safe braking distance curve model, it is determined according to the actual speed of the train at the starting stop position, the train configuration information, and the like. However, during the actual running of the train, road factors such as road gradients in different driving routes will also affect the target running speed of the trai...
