Problems solved by technology

In recent years, countries around the world have attached great importance to the driving safety of urban rail transit, and have carried out several researches on the safety evaluation and analysis of urban rail transit. The evaluation and analysis methods are mainly qualitative analysis methods, including fuzzy comprehensive evaluation methods, hierarchical Analysis method, etc., but the disadvantage of the two methods is that the weight setting is subject to people's subjective influence, and it is difficult to obtain ideal results

Embodiment Construction

[0012] figure 1 It is a flow chart of the identification method for the critical system of urban rail transit train safety, and the method includes:

[0013] S101, the computer collects the number of failures and hazard type information of each subsystem of the urban rail transit train, and the hazard type information includes the number of rescue failures, the number of passenger clearance failures and the number of delay failures;

[0014] The collection method may be reported by each subsystem, or entered into its database in advance, which is not limited in the embodiment of the present invention.

[0015] S102. The computer calculates the equivalent fault quantity of each subsystem of the urban rail transit train;

[0016] The computer calculates the equivalent fault quantity of each subsystem of the urban rail transit train, specifically: the weight of the rescue fault is set to 3, the weight of the passenger-clearing fault is 2, and the weight of the delay fault is 1, ...

Abstract

The invention provides an urban rail transit train safety key system identification method. The method includes the steps that the fault number and harm types of all sub systems of an urban rail transit train are collected, the equivalent weight fault number of all the sub systems of the urban rail transit train is computed, the accumulative frequency is computed, an equivalent weight fault accumulative frequency curve is drawn, the catastrophe point of the curve is solved, and thus a safety key system of the urban rail transit train is identified.

Description

technical field [0001] The invention belongs to the field of traffic safety engineering, and in particular relates to a method for identifying key safety systems of urban rail transit trains. Background technique [0002] Urban rail transit trains run in the semi-enclosed space underground or on viaducts, which have the characteristics of closed environment, small space, and high density of personnel and equipment. Once a traffic accident occurs, it will cause huge personal injury and property loss. The distribution and harm of these faults are not uniform due to the failure of train subsystems. In recent years, countries around the world have attached great importance to the driving safety of urban rail transit, and have carried out several researches on the safety evaluation and analysis of urban rail transit. The evaluation and analysis methods are mainly qualitative analysis methods, including fuzzy comprehensive evaluation methods, hierarchical Analysis methods, etc., ...
