A safety protection model for train dynamic tracking

Abstract

The invention relates to a train dynamic tracking safety protection model. The specific steps are as follows: step 1, establish a dynamic safety braking model, step 2, establish a cooperative collision avoidance mechanism, and the cooperative collision avoidance mechanism is used to prevent continuous collision accidents, step 3, Establish a threat monitoring mechanism, which is a supplementary mechanism when the cooperative collision avoidance mechanism fails; step 4, the dynamic safety braking model, the cooperative collision avoidance mechanism and the threat monitoring mechanism work together to form a dynamic train tracking safety protection model to ensure that the train No rear-end collision under normal driving conditions, even if the vehicle in front collides caused by external factors, continuous collision accidents can be avoided.

Description

technical field [0001] The invention belongs to the technical field of rail transit operation control, and relates to a train dynamic tracking safety protection model. Background technique [0002] my country's urban rail transit industry is in a rapid and sound development stage, but the pressure on rail transit operations in some first-tier cities is becoming increasingly severe. In order to alleviate the operating pressure, it is necessary to effectively improve the driving efficiency under the premise of ensuring safety. [0003] At present, the train operation control system adopted in the field of urban rail transit in my country is the communication-based train control system (CBTC). track. [0004] The tracking target point of the mobile block method is the tail of the preceding train, and the calculation point for the following train to start braking from the highest speed is determined according to the target distance, target speed and performance of the train its...

AI Technical Summary

Problems solved by technology

[0007] 1. In actual operation, it is not realistic and affects the efficiency of train tracking to regard the forward train as a stationary obstacle;

[0008] 2. The "hitting against a hard wall" method only considers the information interaction between the front and rear trains, and cannot obtain information about other trains running in the same direction, resulting in delays in information acquisition, which may cause continuous collisions between subsequent trains
