Abstract

The invention relates to a hydraulic system fault diagnosis system and method. The hydraulic system fault diagnosis system includes signal conditioning module, fault preliminary diagnosis and feature extraction module, fault diagnosis terminal, power supply equipment and sensor equipment connected to the hydraulic system; the sensor equipment is connected to the fault preliminary diagnosis and feature extraction module through the signal conditioning module; fault preliminary diagnosis The fault diagnosis terminal is connected with the feature extraction module; the power supply equipment is respectively connected with the signal conditioning module, the fault preliminary diagnosis and feature extraction module, and the sensor device; the fault preliminary diagnosis and feature extraction module transmits the fault characteristic data of the hydraulic system to the fault diagnosis terminal; The diagnosis terminal diagnoses and analyzes the fault by establishing a fault diagnosis model. Effective preliminary diagnosis of transient faults of the hydraulic system and treatment of slow-change faults, and diagnosis of different types of fault modes of the aviation hydraulic system can meet the high reliability requirements of the aviation hydraulic system.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis of aviation hydraulic systems, in particular to a hydraulic system fault diagnosis system and method. Background technique [0002] Mechanical hydraulic systems are widely used in major equipment such as aerospace, aviation, ships, tanks, and armored vehicles. With the development of equipment technology, the functions and structures of mechanical hydraulic systems have become increasingly complex, large-scale, continuous, and mechatronic. The hydraulic system has the characteristics of multi-variable, nonlinear and strong coupling. The aviation hydraulic system has complex working conditions, various failure modes and complicated mechanisms. The source may lead to the failure of the hydraulic system, and then cause extremely serious consequences. Therefore, it is of great significance to develop research on intelligent fault diagnosis of aviation hydraulic system to ensure the normal ope...
