Method for diagnosing engine integrated faults based on fuzzy semanteme network

Abstract

The invention discloses a method for diagnosing engine integrated faults based on a fuzzy semanteme network. The method is characterized by comprising the following steps: establishing an embedded platform based on an ARM embedded microprocessor and a data acquiring module based on a field programmable gate array (FPGA), and establishing a fault knowledge acquiring method based on a fuzzy semanteme network model, a case-based reasoning subsystem and a guided interactive reasoning subsystem on the embedded platform, wherein the fault knowledge acquiring method based on a fuzzy semanteme networkmodel constructs an engine fault knowledge base; the case-based reasoning subsystem is used for quickly diagnosing frequent faults; and the guided interactive reasoning subsystem adopts a man-machineinteraction mode to carry out fuzzy searching and reasoning and can carry out deep diagnosis of the faults. After the data acquiring module automatically detects a fault symptom or a user inputs a fault symptom, an subsystem can be started independently, and two subsystems can also be started and operated together. Each subsystem can realize fault diagnosis independently, and diagnosis results oftwo subsystems can also be combined to carry out integrated diagnosis so as to improve the accuracy of the diagnosis.

AI Technical Summary

Benefits of technology

This patented technology describes a system that helps identify problems or issues related to engines by analyzing them through various techniques like databases and applications programs. It involves building up a repository called the Acquirement Base (AB) from previous generations of vehicles into a more complex structure containing different components including sensors, actuators, controllers, etc., along with associated software modules and algorithms. These assets help improve vehicle performance while reducing its risk of failure during use. Overall, this approach provides valuable insights about how well these technologies work together to make informed decisions when troubleshootings occur.

Problems solved by technology

The technical problem addressed by this patented method relates to improving the efficiency with which an aircraft's computer system can detect issues such as hardware failures or software bugs that may occur during flight operations due to factors like vibrations caused from turbulence (a phenomenon where airplanes move around).
