Problems solved by technology

However, in the routine detection of airborne oxygen, the pressure of the airborne oxygen system is usually recorded manually, and the oxygen cylinder is replaced according to the hard time limit or when the pressure of the airborne oxygen system is lower than the set value, the aircraft system sends out an alarm. Alarm to replace the oxygen cylinder, which increases the operating cost of the airline. If there is a small leak in the airborne oxygen system, the failure cannot be solved in time, resulting in the operational safety of the aircraft cannot be guaranteed

Embodiment Construction

[0029] The present invention will be further described below in conjunction with specific embodiments. Embodiments of the present invention are not limited to the following examples, and various changes made without departing from the gist of the present invention fall within the scope of protection of the present invention.

[0030] Example. The data processing method of the aircraft system is characterized in that: the aircraft engine bleed air system, the aircraft landing flight system and the aircraft crew oxygen system are respectively processed by triggers, and the data is downloaded to the ground workstation after the data processing is completed.

[0031] The data processing method of the aircraft engine bleed air system is to detect the outlet temperatures of the left and right engine precoolers once per second through the trigger during the three stages of takeoff, climb and descent of the aircraft. If the temperature value is higher than 220 degrees or lower than 15...

Abstract

The invention discloses an aircraft system data processing method comprising the following steps of: respectively carrying out data processing on an aircraft engine air-introducing system, an aircraft landing flight system and an aircraft crew oxygen system through a trigger, and issuing the processed data to a ground workstation after the data processing is finished. By using the aircraft system data processing method, not only can the data be processed, and can fault removal and flight safety be ensured, but also the cost can be saved for airline companies, and the data processing time is saved.

Description

technical field [0001] The invention relates to a data processing method, in particular to an aircraft system data processing method. Background technique [0002] Aircraft system data includes aircraft engine bleed air system data, aircraft landing flight system data and aircraft crew oxygen system data. [0003] The engine bleed air system is the premise to ensure the safe and reliable operation of aircraft air conditioning, pressurization, wing anti-icing, hydraulic pressure and other systems. However, due to the high occurrence rate, high repetition rate, long elimination time and great difficulty, it has become a major problem that has plagued the maintenance work for a long time. At present, conventional methods cannot process data in a timely and accurate manner, so that troubleshooting is not timely, which may lead to flight interruption, and even major unsafe incidents in flight. [0004] In recent years, with the implementation of flight quality monitoring by QAR...
