Locomotive wheel drive running-in test fault automatic diagnosis system

Abstract

The invention discloses a locomotive wheel drive running-in test fault automatic diagnosis system, and relates to the technical field of running-in tests. The system comprises a fault source data acquisition module which provides a multi-source data basis for realizing automatic fault diagnosis and positioning and avoiding manual discrimination; the fault diagnosis module is used for fault diagnosis of locomotive wheel drive running-in; and an automatic diagnosis module. According to the invention, through the fault source data acquisition module, automatic fault diagnosis and positioning are realized, manual discrimination is avoided, a multi-source data basis is provided, and the method and the device are used for realizing synchronous high-quality acquisition and real-time transmission of multi-source sensor data such as vibration speed, vibration acceleration, temperature and noise and multi-source sensing data. Automatic intelligent fault detection and diagnosis are realized through the fault diagnosis module; and data noise reduction, data standardization and data enhancement of the multi-source sensor signals are realized, so that the fault diagnosis performance and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of running-in test, and particularly relates to an automatic fault diagnosis system for a running-in test of a locomotive wheel drive.

Problems solved by technology

[0005] The purpose of the present invention is to provide an automatic fault diagnosis system for locomotive wheel drive run-in test to solve the existing problems: the current locomotive fault detection and diagnosis system is more focused on the real-time monitoring of the running state of the locomotive, and only for specific faults and parts detection , the scalability of the system platform is poor, and a high-precision and high-accuracy fault automatic diagnosis and analysis system platform has not been established for the locomotive wheel drive running-in test bench. The fault diagnosis analysis and positioning still mainly rely on on-site inspection and observation, and Manual discrimination and analysis of test bench sensor data
