Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of aircraft control system design, and particularly relates to a method for improving the man-machine efficiency of aircraft cabin alarm filtering. BACKGROUND

[0002] For aircrafts with high speed and strong maneuverability, the design of cabin alarm directly affects flight safety. Therefore, in order to improve the reliability of cabin alarm, most aircraft cabin alarms adopt a visual and auditory composite alarm mode. The visual alarm generally includes alarm lamp boxes, screen display and display alarm mode, and the auditory alarm generally adopts voice and tone mode. The increase of alarm modes is effective for improving reliability, but everything has its pros and cons. When multiple alarm information appears at the same time, the pilot needs to spend a lot of energy to identify the alarm source among the multiple related alarms, and cannot make correct and reasonable disposal within a limited time.

[0003] Advantages and disadvantages of the prior art: the current domestic aircraft cabin alarm technology has the phenomenon that a single fault source triggers multiple related alarms. This part of the alarm is pushed to the pilot through visual and auditory channels. The pilot needs to spend a certain amount of energy to identify the alarm source among the multiple related alarms and make reasonable and effective disposal measures. When there are many related alarms, the pilot may even fail to accurately identify the alarm source, which greatly reduces the pilot's alarm identification efficiency and disposal efficiency. At the same time, the redundant alarm of the visual and auditory channels will increase the pilot's cognitive load, which has an adverse effect on the pilot's flight safety and completion of the combat task. SUMMARY

[0004] In order to solve the above problems, the present application provides a method for improving the man-machine efficiency of aircraft cabin alarm filtering, comprising:

[0005] establishing a database, including related networks of all alarm information of the aircraft;

[0006] obtaining alarm information triggered by each component after the aircraft is powered on, and dividing the triggered alarm information into a related alarm group and a single alarm group other than the related alarm group through the related network, wherein the multiple alarm information of the related alarm group is divided into a core alarm and a plurality of induced alarms associated with the core alarm;

[0007] warning the core alarm, the single alarm and the induced alarm in different alarm forms.

[0008] Preferably, the specific steps of dividing the alarm information into the related alarm group and the single alarm include:

[0009] Step 1: taking an unmarked triggered alarm information as a reference alarm information;

[0010] Step 2: Obtain the trigger quantity of the alarm information associated with the reference alarm information through the network connection;

[0011] Step 3: When the trigger quantity of the associated alarm information is less than or equal to the threshold value, mark the reference alarm information as a single alarm, take one of the triggered alarm information which is not marked as the reference alarm information, and jump to Step 2 until all the triggered alarm information is marked;

[0012] When the trigger quantity of the associated alarm information is greater than the threshold value, mark the reference alarm information as a core alarm, when the triggered associated alarm information is marked as a single alarm, cover the mark as a induced alarm; when the triggered associated alarm information is marked as a core alarm, keep the mark as a core alarm, take one of the triggered alarm information which is not marked as the reference alarm information, and jump to Step 2 until all the triggered alarm information is marked.

[0013] Preferably, the threshold value is equal to 2.

[0014] Preferably, the core alarm form includes a light alarm, an auditory alarm, or a combination of the light alarm and the auditory alarm.

[0015] Preferably, the single alarm form includes a screen display alarm.

[0016] Preferably, the induced alarm form includes a gray color display alarm at the end of an alarm list.

[0017] Preferably, the induced alarm includes a power supply induced alarm caused by a non-working engine when the airplane is on the ground, a hydraulic subsystem induced alarm, or an induced alarm of related components caused by power failure due to a fault of a certain busbar of the power supply system.

[0018] The advantages of the present application include that the present application can quickly extract a core alarm, use different alarm forms for warning according to the importance of the alarm, greatly improve the alarm recognition efficiency and disposal efficiency of the pilot, reduce the cognitive load of the pilot caused by redundant redundant alarms, and improve the flight safety of the pilot.
