Problems solved by technology

For example, due to long-term flight, some joint parts of the aircraft have problems, insufficient strength, abnormal vibration, or abnormal engine sound, abnormal vibration, etc. It is difficult for the pilot to know these faults
Furthermore, the current analysis of the cause of flight accidents is carried out through the "black box" carried by the aircraft. If the "black box" cannot be found, it will be very difficult to analyze the cause of the accident.

Embodiment Construction

[0012] The method of predicting and alarming aircraft faults is to set corresponding sensors in the parts where the aircraft may fail, and use a computer to collect data from each sensor in a cyclic and uninterrupted manner. The collected data is stored in the computer hard disk, and the flight data analysis and processing program The collected data is analyzed and processed and the data processing results are compared with the normal standard data model. The compared results are used to judge whether the corresponding parts are normal or not. If there is an abnormal situation, the alarm system will be activated to give an alarm. The collected data and analysis results are transmitted to the ground flight command center through the communication network.

[0013] Specifically, the method of the present invention figure 1 , figure 2 As shown, S represents the flight state, and P represents the test point. Suppose the aircraft has m flight states, respectively using S 1 , S ...

Abstract

A method and system for predicting and alarming the failure of aircraft are disclosed. Said method includes arranging different sensors at various positions where it is possible that the failure occurs, continuously acquiring the data from said sensors, storing the data in hard disk, analyzing and procesisng the data, comparing the result with standard data model, starting alarm system if they are not matched, and transmitting the result to ground command center. Said system is composed of sensors, data acquisition unit, computer, alarm system, and the data receiver and monitor in ground command center.

Description

technical field [0001] The invention relates to the field of aircraft flight safety monitoring, in particular to a method for predicting and alarming aircraft faults and an aircraft fault prediction and alarming system. Background technique [0002] With the development of aviation industry, civil aviation becomes more and more popular, and the issue of flight safety becomes more important. Aircraft, especially large passenger aircraft, have many parts and complex equipment, and they have to fly under extremely complex meteorological conditions at high altitudes and are prone to failure. Therefore, civil aviation accidents occur from time to time, and the loss of life and property caused by each aircraft accident is very amazing. of. At present, the safety inspection of aircraft is carried out statically at the airport, and sometimes there are negligence and omissions, which can cause accidents when the aircraft is flown with implicit faults. Although there are various ins...
