A method for using air brakes for automatic driving of heavy-duty locomotives in long-distance downhill scenarios

Abstract

A method for using an air brake for automatic driving of a heavy-duty locomotive in a long-distance downhill scene, comprising the following steps: S1: the heavy-duty locomotive actively implements a penetration test strategy; S2: determining whether the heavy-duty locomotive can perform normally; S3: judging Whether the air brake relief condition is satisfied; S4: determine whether to perform the brake relief operation; S5: confirm whether the heavy-duty locomotive needs to start the air brake; S6: select the air brake application strategy; S7: repeat S3 and S4; S8: The locomotive driver takes over control of the locomotive. The present invention is based on the air-electricity combined speed control and deceleration control strategy based on the train air brake and the locomotive dynamic brake as the auxiliary, which can effectively control the train speed and ensure the safe operation of the train when it grows up and down the slope, and it is a great help for the driver when growing up. The downhill control train operation provides the driver's control guidance, and more effectively plays the role of speed control and overspeed prevention.

Description

technical field [0001] The invention relates to the field of automatic driving control of heavy-duty locomotives in rail transit, and in particular to an air brake application method for automatic driving of heavy-duty locomotives in the scene of long-distance downhill. Background technique [0002] With the continuous growth of my country's economy, the volume of railway transportation is also increasing, and heavy-duty freight trains have played a major role in improving railway transportation capacity and transportation efficiency. At the same time, the continuous promotion and application of locomotive automatic driving technology has effectively reduced driver fatigue, improved the efficiency of railway locomotive use, and further promoted the improvement of my country's railway transportation capacity. However, my country's railway transportation lines are mixed with passengers and goods, the signals are changeable, and the train operating environment is complex. How t...

Problems solved by technology

[0003] The present invention provides an automatic driving air brake application method for heavy-duty locomotives in the scene of long-distance downhill, so as to overcome the problem of heavy-duty trains running on long-distance downhills, especially on continuous long-distance downhills, which only rely on locomotive power braking. The technical problem that the dynamic (electric braking) method will not be able to guarantee the controllable speed of the high-speed train
