Braking control method for a peak-pushing locomotive in hump shunting mode

Abstract

The invention discloses a braking control method for a peak-pushing locomotive under the hump shunting mode, comprising: sending the current operating state parameter signal of the peak-pushing locomotive to the ground camel remote device; The feedback signal of the brake cylinder pressure adjustment value calculated by the parameter signal; the feedback signal is sent to the brake control unit through the network communication interface on the brake control unit of the peak-pushing locomotive, so that the brake control unit can The brake cylinder pressure adjustment value in adjusts the brake cylinder pressure of the peak pushing locomotive. The present invention utilizes the original hardware circuit system of the peak-pushing locomotive to complete the sending and receiving of feedback signals, without additionally adding a dedicated transceiver device, avoiding modification of the hardware circuit system of the peak-pushing locomotive, and realizing the peak-pushing locomotive on the hump at low cost. Brake control in shunting mode. The invention also discloses a brake control system for a peak-pushing locomotive in a hump shunting mode, and its beneficial effect is as above.

Description

technical field [0001] The invention relates to the technical field of locomotive braking and communication, in particular to a braking control method for a peak pushing locomotive in a hump shunting mode. Background technique [0002] Hump ​​shunting is to raise a part of the railway roadbed to a certain height at the marshalling station, forming a hump-like height difference with the conventional roadbed and designing it into a suitable slope. Using the potential energy generated by the gravity and height difference of the vehicle, the marshalling will be required. The vehicle is pushed to the top of the hump by a locomotive, that is, the hump is pushed, and the vehicle is unhooked on the hump, that is, the hump is disintegrated, and the train is slid down to the bottom of the hump to reach the marshalling yard. The locomotive used for pushing in this process can be called peak pushing locomotive, and the hump pushing operation is also called peak pushing operation. [00...

Problems solved by technology

However, this method needs to add an additional braking junction box on the locomotive brake to receive instructions. For the highly complex and sophisticated wiring system of the locomotive braking system, this kind of modification is troublesome to implement, and requires the electrical interface of the brake Re-wiring, the wiring is difficult, and it also has an adverse effect on the reliability of the brake
