Online monitoring and fault diagnosis system for automobile engine

Abstract

The invention discloses an online monitoring and fault diagnosis system for an automobile engine. The system is composed of a state monitoring system and a fault diagnosis system. The state monitoringsystem consists of a signal measuring module, a signal processing module, a data collecting module and an industrial control computer; and the fault diagnosis system includes a real-time monitoring module, an alarm module, a fault diagnosis module, a fault prediction module, a self-learning module and a printing module. The online monitoring and fault diagnosis system for an automobile engine isdesigned and erected. With fuzzy control and an expert system, the fault of an engine is analyzed systematically; a fault cause can be found out quickly and accurately; a problem processing efficiencyis improved; and the maintenance time is saved. On the basis of the modular structure design, the flexibility of the system is improved and interdependence between the layers is reduced.

Description

Technical field [0001] The invention relates to the technical field of automobile parts, and the specific field is an online monitoring and fault diagnosis system for automobile engines. Background technique [0002] With the rapid development of the automobile industry, automobiles have become the carrier of electro-mechanical-hydraulic integration. The wide application of various electronic technologies has brought huge challenges to automobile maintenance personnel. The engine is the source of driving power for automobiles, due to its mechanism Complexity, many parts, poor working conditions, etc., are the most common in automobile failures, so online status monitoring and fault diagnosis are necessary. [0003] The intelligent fault diagnosis technology used at this stage is mainly to perform fault detection and analysis after the car engine fails, which extends the maintenance time to a certain extent. With the continuous development of technology, fault diagnosis sensors can...
