A method and device for health diagnosis of rail transit vehicles

Abstract

The invention provides a health diagnosis method and device suitable for rail transit vehicles, including: collecting and preprocessing the whole life cycle data of rail transit vehicles based on the workshop service system to form a label data set; using self-adaptive antlion strategy and virtual construction Modeling technology to build a digital twin health analysis model, input the label data set into the data twin model for training; judge the training results according to the Bayesian judgment principle, and output the model if the Bayesian judgment principle is satisfied It is a vehicle digital twin health diagnosis model; the rail transit vehicle data to be diagnosed is input into the vehicle digital twin health diagnosis model in real time for health diagnosis, and the final diagnosis data is calculated and output. The invention can accurately analyze the health status of rail transit vehicles in real time, provide operation decision information for users, avoid traffic accidents caused by vehicle health, reduce social threats, and ensure the safety of passengers and drivers.

Description

technical field [0001] The invention relates to the fields of digital twin signal processing technology and Internet technology, in particular to a method and device suitable for rail transit vehicle health diagnosis. Background technique [0002] With the development of society and economy, urbanization has become an important trend in the development of the world today. In the process of urbanization, cities of different scales and stages of development have different traffic needs, which require corresponding traffic technology levels and transportation From the perspective of the development practice of many international metropolises, rail transit has become an indispensable part of the urban traffic structure due to its technical advantages of large capacity and fast speed. The contradiction between supply and demand in urban transportation is increasing day by day, and meets the requirements of urbanization. With the deepening of urbanization, urban rail transit has b...

Problems solved by technology

[0003] Existing technology can only rely on historical vehicle data for simple parameter analysis, and the results obtained are too rough, resulting in excessive errors. With the development of the new generation of information technology, the application of digital twin technology is not very mature, so in the fusion There are also large deviations in the use process. In order to better protect urban development and user safety, accurate analysis of the health status of rail transit vehicles is a major problem that needs to be solved urgently.
