Problems solved by technology

[0005] However, in order to ensure safety, it is necessary to set up a protection zone, which has a certain impact on the passing capacity of the line, and because the train speed in the zone cannot be monitored, or it is difficult to cover the entire route with dense zones, it is difficult to realize the protection of the zone. Real-time control of train speed

Embodiment Construction

[0031] Heavy-duty combined trains are very different from ordinary single-braided trains in terms of traction weight, traction and braking characteristics, resulting in significant differences in response time to signals and braking protection distances from ordinary single-braided trains. Therefore, the heavy-duty combined train needs a special protection mode curve to realize the heavy-duty overspeed protection.

[0032] The speed control method for combined train operation of the present invention uses the operating parameters of the target object as reference information to control its own speed. Wherein, the target object can be a static target, such as the entry point of a station (the speed parameter in the corresponding operation parameter is 0), and can also be a dynamic target, such as the adjacent previous train, the location of the track block partition where the previous train runs Entry point (listed as a dynamic target because the operation of the previous train...

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...
