AI Technical Summary

Technical Problem

The prior art is difficult to effectively monitor and early warning of pilots' abnormal operations, making it difficult to prevent possible flight safety accidents.

Method used

The pilot operation monitoring method based on the ‘threshold-feature-result’ matching is adopted. By recording the pilot’s operation data in real time, the matching situation with the standard threshold is compared, and the operation results are verified using the six-degree of freedom simulation aircraft model to accurately determine the pilot’s abnormal operation intention and level.

Benefits of technology

Accurate monitoring and early warning of pilot abnormal operations is achieved, the probability of false alarms is reduced, misjudgment caused by environmental or mechanical failures is avoided, and flight safety is improved.

Abstract

The present invention discloses a pilot operation monitoring method based on "threshold-feature-result" matching, which belongs to the field of aircraft design. First, the pilot's historical abnormal operations are divided into three categories: flight technical errors, emergency operations, and intentional operations. Four characteristic data, namely, the operation amplitude, time, frequency, and control of the aircraft to reach a stable / unstable state, of the pilot to be tested are recorded in real time. The operation is compared with the standard threshold respectively. When the pilot's operation exceeds the threshold, an abnormal operation occurs. Then, the abnormal operation is input into a six-degree-of-freedom simulation aircraft model. By comparing the model results with the actual results, the influence of the aircraft system failure is deleted to ensure that the control result is generated by the pilot's operation. Finally, the "threshold-feature-result" matching relationship is used to judge the control result generated by the pilot's current operation, and the pilot is given an alarm level judgment. The present invention can accurately determine the cause of abnormal operation and reduce the probability of false alarms.
