Abstract

The invention provides a dynamic safety analysis method for a train virtual formation. The method comprises the following steps: S1, obtaining train parameter information and line operation parameter information in a line; s2, establishing a single-vehicle motion model of the train, and obtaining a state updating equation of the train; s3, establishing a virtual formation train operation model under the relative coordinate system according to the state updating equation; s4, calculating the minimum safety distance between trains; s5, establishing a space-time set C, and calculating the distances between different trains in real time through the space-time set C so as to judge whether the trains are in a dangerous state or not. According to the method, the distance between the two trains is circularly calculated in real time through the space-time set C, so that risks are reduced to the maximum extent, and the train operation safety is improved.

Description

technical field [0001] The invention relates to the technical field of railway train control, in particular to a dynamic safety analysis method for train virtual formation. Background technique [0002] As the demand for railway transportation around the world continues to grow, countries have begun to focus on further improving the transportation capacity of railways. The rail industry works to increase the capacity of lines and improve current rail operations. The general approach is to meet this growth by increasing the number or capacity of existing rail lines, but this solution involves building new lines and is often very expensive. Therefore, the concept of "virtual train formation" is proposed to realize the rational allocation of traffic resources. [0003] Virtual formation (virtual coupling, VC) can be said to be a new way of train operation. As the name implies, trains form formations through vehicle-to-vehicle communication, so that the rear vehicles can obtai...
