Embodiment Construction

[0037] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0038] The safety domain of the rail transit system is a space determined by various safety-related variables of the system (such as speed, track irregularity, safety interval, pantograph-catenary voltage / current, crosswind, etc.), and is used to evaluate whether the system operating state is The safe area, and the relative relationship between the safe domain boundary and the system operating point can provide the operating safety margin and optimal control information under different conditions of the system, such as figure 1 shown. Therefore, it can directly give the quantitative safety status evaluation results of the evaluation object and perform trend estimation, providing support for improving the safety assura...

Abstract

The invention discloses an operation safety assessment method for rail transit systems in the traffic technique and safety technique field. The method includes confirming safety correlated variables of an assessment object; obtaining data of the safety correlated variables; preprocessing the data of the safety correlated variables; determining security domain boundaries of the assessment object; and conducting safety assessment on system operation. According to the assessment method, quantitative safety state assessment and trend prediction of the rail transit systems and local subsystems or key equipment of the systems are achieved, and the assessment method has great theoretical and practical significances for achieving high level security of the rail transit systems.

Description

technical field [0001] The invention belongs to the field of transportation technology and safety technology, and in particular relates to a method for evaluating the operation safety of a rail transit system. Background technique [0002] Rail transit system operation safety assessment is the premise and necessary scientific means to ensure its safe operation. With the rapid development of the rail transit industry, the corresponding system operation safety assessment problem has become a key problem that needs to be solved urgently. However, the existing qualitative, static, and individual equipment safety assessment methods cannot meet the needs of accurate safety status information analysis, dynamic safety evaluation, and large-scale system safety analysis. Quantitative, dynamic systems are urgently needed to ensure the safe and efficient operation of rail transit systems. Theory and method of operational safety assessment which can be simplified and analyzable. Theref...
