Embodiment 1

[0037] see Figure 1-2 , an aviation transmission failure data analysis system, comprising a data acquisition module and a detection host; the data acquisition module includes a sensor and a data collector; the monitoring host is provided with a management system module, a communication module, a data processing module, and a data storage module , a monitoring analysis module, a fault diagnosis module, and an alarm indication module; the sensor is an eddy current sensor and a piezoelectric acceleration sensor; the eddy current sensor is arranged on the rotor rolling bearing of the transmission system to measure the vibration of the rolling bearing, and the piezoelectric A type acceleration sensor is arranged on the inner wall of the transmission casing to measure the vibration of the casing; the data collector collects the speed and vibration signals of the aviation transmission system.

[0038] The management system module includes: a data layer, an intermediate layer, and an...

Embodiment 2

[0046] see Figure 1-2 , an aviation transmission failure data analysis system, comprising a data acquisition module and a detection host; the data acquisition module includes a sensor and a data collector; the monitoring host is provided with a management system module, a communication module, a data processing module, and a data storage module , a monitoring analysis module, a fault diagnosis module, and an alarm indication module; the sensor is an eddy current sensor and a piezoelectric acceleration sensor; the eddy current sensor is arranged on the rotor rolling bearing of the transmission system to measure the vibration of the rolling bearing, and the piezoelectric A type acceleration sensor is arranged on the inner wall of the transmission case to measure the vibration of the case; the data collector collects the speed and vibration signals of the aviation transmission system.

[0047] The state of the aviation transmission system is divided into 3 categories: normal, ab...

Embodiment 3

[0052] The difference from Embodiments 1 and 2 is that the data storage module is a database, and the SQLServer database is used to manage data and data backup. The database is responsible for receiving the data sent by the acquisition module, and corresponding to the query and update data requests of the data processing module.

[0053] The model of the eddy current sensor is 3300XL-11mm eddy current sensor; the piezoelectric acceleration sensor is Kistler9640A50 sensor.

[0054] This system is actually developed in C# language on the Visual Studio 2015 platform, uses ADO.NET technology to access the database, and cooperates with the SQLServer database to achieve efficient development of the system.

[0055] In addition, the fault diagnosis method is as follows: S1, detection and analysis data feature extraction, data segmentation is first performed during the original data processing, and then feature extraction is performed on each segment of data, and data such as time doma...

Description

technical field [0001] The invention belongs to the field of aviation transmission fault equipment, in particular to an aviation transmission fault data analysis system. Background technique [0002] The supporting transmission system of the aero-engine is an important part of the aero-engine and the heart of the aircraft. Once a failure occurs, it often leads to serious flight accidents; the core components of the supporting transmission system are rolling bearings and drive shafts. The existing fault diagnosis methods mostly use The types of bearing faults are analyzed simultaneously without dismantling, and the vibration signal is proposed for aero-engine bearings and drive shafts. [0003] At present, my country is vigorously developing the aviation industry and has achieved certain excellent results. However, my country currently does not have an advanced and mature aviation transmission system fault detection and diagnosis system that can provide effective technical su...
