Abstract

The invention provides a running speed control method of a combined train. The method comprises following steps: A, the present distance between the train and an object is confirmed; B. the present safe braking distance between the train and the object is calculated; C, when the present distance between the train and the object is judged to be smaller than the safe stopping distance, a braking mode curve is generated to perform braking. By adopting the method, the speed of the combined train can be controlled in real time on a whole rail way, and the signaling security of the transportation of the train can be improved.

Description

technical field

[0001] The invention relates to the technical field of multi-locomotive operation control for heavy-duty combined train transportation, in particular to a speed control method for combined train operation. Background technique

[0002] The problem of insufficient traction of locomotives often occurs in heavy-duty transportation. It is necessary to increase the number of locomotives in the train formation, which is pulled by two or more locomotives at the same time, which is called combined train multi-locomotive heavy-duty transportation. With the development of heavy-duty transportation and the highlight of potential safety hazards, the length, speed and weight of heavy-duty trains are continuously increasing, and the running density is increasing. Signal safety protection technology is applied to heavy-duty and multi-locomotive traction trains , It is necessary to ensure the operation safety of heavy-duty trains under the signal system of existing lines, an...
