Problems solved by technology
The original aircraft hydraulic system support system is facing huge challenges under the new equipment conditions, and if the support is not in place, the combat readiness rate of military aircraft will be greatly reduced
[0003] The fault identification of the aircraft hydraulic system lacks quantitative analysis, and the experience and data accumulated in the actual use and maintenance process have not been well combined with the design data for analysis, resulting in a separation between theory and practice
There is no automatic identification mechanism for the fault state of the aircraft hydraulic system. When the maintenance personnel of the maintenance field equipment detect the fault state of the aircraft hydraulic system, it is difficult to know the fault state of the aircraft hydraulic system, and the lack of predictability makes it difficult to accurately predict the fault state of the aircraft hydraulic system.
[0004] When the hydraulic system of the aircraft fails, it is difficult for the field maintenance personnel to conduct a clear abnormal detection based on the comprehensive analysis of the fault phenomenon, reliability data, index data, etc., so it is difficult to find the optimal abnormal detection method
This increases the maintenance cost of the aircraft hydraulic system, and the hydraulic system cannot be well maintained, resulting in a waste of resources

The invention provides an airplane hydraulic system fault identification method and device, and a readable storage medium, and the method comprises the steps: obtaining N types of flight parameter data, sensitive to a hydraulic system fault, of a plurality of sorts of an airplane, and constructing a time sequence data set; carrying out data preprocessing on a time series data set constructed by the N hydraulic system parameters; dividing a time series data set constructed by the N hydraulic system parameters into a time series data set with a marked fault state and a time series data set without a marked fault state; constructing an aircraft hydraulic system fault identification model based on semi-supervised learning by utilizing the N hydraulic system parameters; and determining the actual fault state of the aircraft hydraulic system according to the aircraft hydraulic system fault identification model based on semi-supervised learning and the real data set. The aircraft hydraulic system fault identification model based on semi-supervised learning is adopted to identify the fault of the aircraft hydraulic system, and the fault condition of the aircraft hydraulic system can be effectively identified.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a semi-supervised learning-based aircraft hydraulic system fault identification method for a military flight big data maintenance field autonomous support information support system. Background technique [0002] From the 1990s to the present, aviation equipment technology has developed rapidly, especially in the context of the adjustment of military strategy and changes in the combat use of aviation equipment, the requirements for aircraft ground support are getting higher and higher, and the hydraulic system of aircraft support is among them. is the most fundamental factor. The rapid development of military technology has put forward higher requirements for aircraft support and failure prediction. However, in the long-term development, the support technology of the aircraft hydraulic system always lags behind the technology of other aerospace equipment. The original aircraf...
