Train driving aiding method and train driving aiding system

Abstract

The invention provides a train driving aiding method and a train driving aiding system. The method comprises the following steps of presetting a running line database which comprises a corresponding relation between position information of an early warning point and early warning information and a corresponding relation among train arrival time information, brake frequency and running information; recording each corresponding relation as a scheme; acquiring the position of the train; acquiring position information of a next early warning point; calculating an early warning distance between the train and the next early warning point according to the position of the train and the position information of the next early warning point; displaying the early warning information corresponding to the position information of the next early warning point when the calculated early warning distance is smaller than or equal to a preset value; and screening out a preferred scheme according to the train arrival time information and the brake frequency of the train. The running information is determined according to the preferred scheme and is displayed. By the method and the system, lots of driving reference information can be provided for a driver.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a train driving assistance method and system. Background technique [0002] The important position of rail transit in social life and social economy determines the importance of rail transit driving safety. In the train control system, ATP (Automatic Train Protection, train overspeed protection system) is mainly used to support the driver to drive the train to ensure the safety of the train. ATP is used to prevent train speeding, collision and other dangerous situations that may occur when the train is running. ATP compares the actual speed of the train with the maximum safe speed. If the actual speed of the train exceeds the maximum safe speed, the system will command the train to perform emergency braking to avoid the train from overspeeding. There is enough unoccupied road ahead for the trains to stop without colliding. [0003] From the above description, it can be...

AI Technical Summary

Problems solved by technology

[0003] From the above description, it can be seen that when the speed of the train exceeds the speed limit value of the line, ATP automatically applies the brakes, which can ensure the safety of the vehicle, but it loses the energy of the train and provides less driving reference information for the driver
