Problems solved by technology

[0004] In other words, the existing locomotive engine monitoring, alarm and security systems still do not have the ability to intelligently diagnose and predict engine faults in advance, and cannot change the maintenance strategy of locomotive engine fault repair and fixed-mileage repair. It is not ideal in terms of reducing the failure rate of locomotive engines, or the timeliness of operation and maintenance, management, and cost

Abstract

The invention provides a locomotive engine fault diagnosis method which is characterized by comprising the following steps: collecting engine state parameter information; state grading is conducted onthe engine state parameters; and giving a fault source causing state grading according to a pre-established fusion diagnosis model. The invention also provides an engine fault diagnosis system and adevice for realizing locomotive engine fault diagnosis. Fault diagnosis of the intelligent locomotive engine can be realized. The fault rate of the locomotive engine is reduced. The operation and maintenance timeliness is improved and operation and maintenance cost is reduced.

Description

technical field [0001] The present invention generally relates to the field of fault diagnosis, and more specifically, relates to a locomotive engine fault diagnosis method, system and implementation device. Background technique [0002] With the rapid development of modern industrial technology, especially sensor technology, embedded system, network communication technology, and information technology based on big data, engine fault diagnosis technology has begun to be researched and applied in various fields at home and abroad, involving aviation, aerospace, ships, locomotive and other industries. . [0003] At present, the engine fault diagnosis technology of locomotive engines is mainly based on monitoring, alarm and security systems, and mature fault diagnosis systems and products have not yet appeared. The operation and maintenance methods still adopt post-fault maintenance and planned maintenance according to the running time or mileage of the locomotive. Strategy. ...
