Method and device for division of safety protection scenes of cooperative formation trains

Abstract

Embodiments of the present invention provide a method and device for dividing safety protection scenarios of coordinated formation trains. The method includes: for any two trains in the coordinated formation that are kept within a preset fixed interval during operation through the virtual connection control technology, obtain the previous The parking time of the car, the parking time of the rear car and the traction time of the rear car; judge whether the parking time of the front car is greater than the traction time of the rear car; if so, judge whether the parking time of the front car is greater than the parking time of the rear car If so, it is determined that the current two marshalling trains belong to the first safety protection scene and the third safety protection scene, and the first safety protection scene is the collision scene when the rear car is in the traction state and the front car is in the moving state , the third safety protection scene is a collision scene when the rear car is in an emergency braking state and the front car is in a moving state. The embodiment of the present invention can regard the vehicle in front as a moving state instead of a stationary state to realize the division of safety protection scenes.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and device for dividing safety protection scenes of coordinated formation trains. Background technique [0002] Train cooperative formation is a new type of train cooperative driving mode. It is based on the mobile block, through the information interaction and induction between trains, and under the condition of ensuring the safety of the trains, it realizes the flexible operation of two or more trains through virtual connection technology. The purpose of marshalling, the convergence of section speeds and the same entry and exit platforms, thereby improving the efficiency of subway operations and reducing operating costs. [0003] The traditional automatic train protection system ATP (Automatic Train Protect) calculates the maximum speed limit of the train by obtaining the position of the obstacle in front and the speed information of the vehicle through the sensor...

AI Technical Summary

Problems solved by technology

[0004] However, in the coordinated formation of trains, if the rear train regards the train in front as an obstacle, then the obstacle in front is in a state of constant motion, and the relative interval between the two trains after reaching the coordinated state is relatively short. The traditional ATP protection can no longer meet the needs of train coordinated formation The protection needs of the rear car
