Abstract

The invention discloses a gradient processing method and device for a train automatic operation system. Firstly, a gradient information list corresponding to a train covered line is obtained; then the equivalent gradients of the train covered line are calculated according to the gradient information list; the complementary acceleration of a train is calculated according to the equivalent gradients, and acceleration needed to be applied is calculated by combining train control acceleration obtained through a train control algorithm; finally, the gear for controlling the train is determined according to the acceleration needed to be applied. According to the gradient processing method and device for the train automatic operation system, the equivalent gradients are calculated from the angle of the whole train covered line, the deviation of the equivalent gradients and the actual gradients can be reduced, and accurate and effective train control of the ATO is guaranteed.

Description

technical field [0001] The invention relates to the technical field of train control, and more specifically, relates to a slope processing method and device for an automatic train operation system. Background technique [0002] ATO (Automatic Train Operation, automatic train operation) system is a key subsystem in the automatic train control system. ATO runs under the safety protection of the automatic train protection system, and can complete the start, acceleration, cruise, The control of coasting and braking realizes the automatic driving of the train. For example, according to the arrival time, departure time, travel time interval or travel speed in the operation plan instructions, and according to different line conditions, the purpose of automatically adjusting the train operation is achieved. [0003] In the application process of ATO, lines with a certain slope are often encountered. The existing ATO slope processing method is as follows: the actual line slope infor...
