Fault logical modeling method for high speed railway train operation control vehicle-mounted system

Abstract

The invention discloses a fault logical modeling method for a high speed railway train operation control vehicle-mounted system, and belongs to the technical field of fault diagnosis for a train operation control system. According to the fault logical modeling method for the vehicle-mounted system, components and function modules of the vehicle-mounted system are fully described respectively according to the system research and development process of a UML (Unified Modeling Language) model, particularly in an input fault mode and in an internal fault and output fault mode, and the description can exist in a table, text or diagram manner. Then, a fault logical model of the train control vehicle-mounted system is combined, and the fault logical model is simulated so as to obtain a fault propagation path and fault results. The analyzed fault mode is more systemic, and the fault logical modeling is easier from an overall point of view, so that the complexity of safety analysis for the train control system is effectively reduced in a targeted manner, and the development cycle of the train control system is shortened.

Description

technical field [0001] The invention belongs to the technical field of fault diagnosis of a train operation control system, and in particular relates to a fault logic modeling method for a high-speed railway train operation control vehicle-mounted system. Background technique [0002] The train operation control system is an important part of China's railway technology system and equipment modernization, and one of the core technologies to ensure the safe, reliable and efficient operation of high-speed trains. Once the system fails, the result is often catastrophic. With the rapid development of the national economy, the acceleration of urbanization, the expansion of railway construction scale and the further increase of train speed, the high-speed railway operation control system has played an increasingly important role, which also means that the train control system is safe, Efficient operation puts forward higher requirements. [0003] The on-board system is an importa...

Problems solved by technology

[0005] Most of the above methods are highly subjective and rely on the skills of the participants. These analyzes are usually based on informal system models, and it is difficult to be complete, continuous and error-free, which affects the reliability analysis of the train control system to a certain extent , poses a potential threat to the safety of people's lives and properties, and there is an urgent need for a method that can describe and analyze the inherent characteristics of the train control system itself
