Intelligent trouble diagnosis method for high-speed rail

Abstract

The invention relates to an intelligent fault diagnosis method for high-speed rail. A high-speed rail operating state sensor detects various parameters in the high-speed rail operating state; sends each detected operating state to a digital-to-analog conversion module; and the digital-to-analog conversion module receives the received The data is converted from analog to digital; the signal amplification module amplifies the converted digital signal; the filter module filters the amplified digital signal; the self-diagnosis unit module comprehensively diagnoses the filtered digital signal to obtain the first diagnosis result; self-diagnosis The unit module sends the first diagnosis result to the data receiving module of the maintenance service center; the data analysis module performs the second diagnosis on the first diagnosis result; the maintenance decision feedback module feeds back the second diagnosis result to the high-speed rail system, and the high-speed rail system makes a decision on the received second diagnosis result Subsequent decisions are made to complete fault diagnosis. The invention has good reliability, realizes fast and automatic diagnosis of faults in the brake system of high-speed trains, and improves the safety of train operation.

Description

technical field [0001] The invention relates to a fault diagnosis method, in particular to an intelligent fault diagnosis method for high-speed rail. Background technique [0002] As a whole, high-speed rail is composed of complex technical equipment, operates in a complex environment, and completes displacement services with complex temporal and spatial distribution characteristics. It is a complex networked giant system. Once it fails, it will cause great harm. Moreover, due to the many components and various detection parameters of high-speed trains, the types of faults that occur are also complex and diverse, including: sudden faults, cross faults, combined faults, and chain faults. And different reasons may also produce the same fault phenomenon, which makes the fault diagnosis and maintenance of high-speed trains more difficult. [0003] At present, the maintenance of high-speed trains basically depends on the experience of relevant technical personnel, and the existi...
