Engine fault diagnosis alarm system and device

Abstract

The invention discloses an engine fault diagnosis alarm system and device, and aims to solve the problems that fault diagnosis depends on experience, the automation degree is low and massive signals are difficult to manage in the field of engine fault diagnosis. The engine fault diagnosis and alarm system and device is a comprehensive system which integrates a sensor, an acquisition card, signal acquisition, signal display, data cloud storage, fault diagnosis and abnormal fault data alarm. The acquisition card is controlled by fault diagnosis client software to read vibration signals acquired by a vibration sensor attached to the surface of an engine in real time; faults are automatically diagnosed by using an artificial intelligence technology, and real-time alarm of the faults is realized in combination with software; automatic storage and recording of vibration signals and diagnosis data are realized, two hands of a worker are liberated, and the efficiency and accuracy of engine fault diagnosis are greatly improved; the system is high in functionality, friendly in man-machine interaction and capable of supporting multi-channel multi-sensor expansion; and the system and device is applied to aircraft engine fault diagnosis.

Description

technical field [0001] The engine fault diagnosis and alarm system and device involved in the present invention are mainly for diagnosing, alarming and massive data management for engine faults. Background technique [0002] Aviation engine is a kind of highly complex and precise machinery, it is a device that provides propulsion or support for aircraft, it is the "heart" of spacecraft, known as the jewel in the crown of industry, and it is an important impetus to promote the rapid development of aviation industry Power is the part with the most complex technology, the highest technical difficulty and the most expensive cost in the aerospace industry, and its reliability and safety requirements are also the highest. The development of aero-engine technology plays an extremely important role in national defense and national economy. Every major revolutionary progress of human beings in the field of aviation is closely related to the breakthrough and progress of aerodynamic te...

AI Technical Summary

Problems solved by technology

[0009] At present, there are several problems in the fault diagnosis based on vibration signals: (1) Fault diagnosis depends on experience, and the degree of automation is low: the traditional fault diagnosis is based on software diagnosis. Workers observe the frequency spectrum of each sensor and judge through experience Whether the equipment is abnormal

However, at present, enterprise test benches may come from different manufacturers, and the data cannot be managed because they are not compatible with each other.

Most of them are stored on disk and do not play the role of application

(3) Fault alarm: Traditional monitoring relies on human resources to manually judge faults, and the system does not warn of faults
