Embodiment

[0034] Such as figure 1 As shown, a rail transit safety analysis method based on the 5M model includes the following steps:

[0035] S1. Obtain the tasks, equipment, personnel, environment and management factors of the rail transit system to construct a 5M model of rail transit. Among them, the task factors are specifically the rail transit traffic safety tasks, and the goals of the rail traffic traffic safety tasks include:

[0036] Guarantee of train access safety: before a train is authorized to move along the track, that part of the line should be demonstrated to be safe, to prevent derailment and to avoid conflicts with other train movements, and except in cases where a train is allowed to enter an occupied line, It should be demonstrated that there is no other traffic on the line to prevent collisions;

[0037] The security of the line shall be maintained after authorizing a portion of the zoning along the line;

[0038] Train Movement Authorization Assurance: Provides...

Abstract

The invention relates to a rail transit safety analysis method based on a 5M model. The method comprises the steps that the task, equipment, personnel, environment and management factors of a rail transit system are acquired, so as to construct a rail transit 5M model; and according to a set temporary speed limit safety rule, safety analysis is carried out based on the rail transit 5M model to determine a current temporary speed limit command, and specific key hidden danger factors are identified. Compared with the prior art, the method has the advantages that the elements influencing the safety of the rail transit system and the interrelation thereof can be comprehensively identified, so that the safety analysis is comprehensively and accurately performed on the rail transit system, and the potential safety hazard of the rail transit system is identified.

Description

technical field [0001] The invention relates to the technical field of rail transit train operation safety, in particular to a 5M model-based rail transit safety analysis method. Background technique [0002] Rail transit is an important part of the operation of modern cities, and its safety is closely related to people's lives. With the development of new technologies such as communication, control, computer, and artificial intelligence, the automation of rail transit is getting higher and higher. The road traffic industry is The development and testing of unmanned driving is in full swing, and the driving automation of urban rail transit has gradually developed from the traditional manual visual driving mode to the unattended fully automatic operation mode. However, due to the increase in the coupling of factors such as roads, equipment, personnel, and the environment that make up the system, the security of the system will inevitably become more complicated. [0003] In ...
