Problems solved by technology

For non-automated railway locomotives, there are disadvantages such as low average speed, poor safety, and inaccurate parking, and the driver's driving skills seriously affect the operation of the train
The driver's driving skills rely on long-term practice and continuous accumulation of experience, and he is only accustomed to driving on one route, so it is difficult to achieve the optimal control effect

Embodiment Construction

[0044] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0045] The present invention provides a train ATO overspeed safety prevention method, which first optimizes and adjusts the original train automatic driving speed curve generated by the ATO system according to the high-speed limit and low-speed limit, and obtains the optimized and adjusted train automatic driving speed curve; then During the running process of the locomotive according to the optimized train automatic driving speed curve, the running speed of the train is tracked in real time. When it is confirmed that the current running speed of the train has an overspeed trend, the brake is adjusted in real time; The speed limit factor maintains a safety protection curve, and when it is confirmed that the current train running speed exceeds the safety protection curve, it is considered that the train is overspeeding, and the corres...

Abstract

The invention relates to an automatic train operation (ATO) overspeed safety precautionary method for a train. The ATO overspeed safety precautionary method for the train comprises the steps that an original train automatic operation running speed curve is optimized and adjusted according to high speed limit and low speed limit; the actual running speed of the train which runs along the optimizedand adjusted train automatic operation running speed curve is tracked; when the situation that the train has the overspeed trend is confirmed, a brake gear is adjusted in real time according to the high speed limit value until the train runs according to the optimized and adjusted train automatic operation running speed curve again; and when the situation that the train is overspeed is confirmed,corresponding braking measures are taken on the train based on the comparative result between difference value of the train actual running speed and the safety protection curve and the critical threshold until the train continues to run along the optimized and adjusted train automatic operation running speed curve after the train actual running speed tends to the optimized and adjusted train automatic operation running speed curve. According to the ATO overspeed safety precautionary method for the train, multiple safety protection can be conducted on train overspeed in stages, so that train safety performance is more ensured.

Description

technical field [0001] The invention relates to the field of railway transport dispatching, in particular to a safety prevention method for train ATO (Automatic Train Operation, automatic driving) overspeed. Background technique [0002] As a common means of transportation, railway locomotives have the characteristics of huge transportation volume, high speed and long transportation distance. With the rapid growth of the flow of people and goods between regions, more safety, stability and energy-saving requirements are put forward for locomotive driving. For railway locomotives with non-automated driving, there are disadvantages such as low average speed, poor safety, and inaccurate parking, and the driver's driving skills seriously affect the operation of the train. The driver's driving skills rely on long-term practice and continuous accumulation of experience, and he is only accustomed to driving on one route, so it is difficult to achieve the optimal control effect. Th...
