Problems solved by technology

How to issue warnings to the flight crew in real time based on this information? One method is to rely on sub-equipment to report alarm information, and remind the flight crew through sound, light, etc. This method has certain limitations, and it is not convenient to combine alarms based on multiple subsystems, and the amount of alarm information is limited
Another method is to centralize the data of each subsystem into a class of equipment, and judge whether the communication is normal by counting and comparing data frames, etc., which is more complicated to deal with in system integration

Embodiment Construction

[0031] The present invention processes the alarm information through a message mechanism on the basis of the general aircraft avionics system architecture, and the overall flow of the processing method is as follows: figure 2 shown. The best embodiment of the present invention is given below and described in detail in conjunction with the accompanying drawings. The perfection and optimization of the basic solution of the present invention in this embodiment should not be regarded as limiting the claims of the present invention.

[0032] Tasks related to alarm processing tasks trigger the processing of alarm information by sending messages to alarm processing tasks. Tasks related to alarm processing tasks include:

[0033] A. tasks for processing sensor device data;

[0034] B. Handle the task of sensor device self-test status;

[0035] C. Handle the task of self-test status of integrated processor;

[0036] D. Key task.

[0037] The task flow of the above four trigger...

Abstract

The invention provides a method for processing aviation electronic system warning information, which is suitable for a general-purpose aircraft. The method comprises the steps of: (1) dividing equipment information required to be monitored in a general-purpose aircraft aviation electronic system into four classes, setting a warning information list on an airborne display, and respectively establishing corresponding warning processing tasks for the four classes of equipment information; (2) receiving messages sent by the warning processing tasks, judging whether the messages are key messages firstly, if so, directly turning to a step (4), otherwise, carrying out a next step; (3) judging whether the messages are adding warning messages, and if so, adding corresponding warning information into the warning information list, otherwise, indicating the messages to be deleting warning messages, and deleting corresponding warning information from the warning information list; and (4) sequencing and displaying the warning information list. The method has the advantages of simplicity, stability, real time, strong testability and expandability, and the like.

Description

technical field [0001] The invention relates to a method for processing alarm information of an avionics system. Background technique [0002] A variety of devices are integrated in the general aircraft avionics system, such as integrated display (PFD, MFD), integrated processor, radio compass, Volt / head down multi-mode navigator, VHF radio, S-mode transponder, DME tester, etc. distance machine, attitude system, atmospheric computer, audio controller, engine parameter collector, fuselage state parameter collector, etc. The cross-linking relationship between them is as follows: figure 1 shown. [0003] With the continuous development of general aircraft avionics systems, more and more electronic devices are integrated, and these electronic devices concentrate a large amount of data on a certain type of device. How to issue warnings to the flight crew in real time based on this information? One method is to rely on sub-equipment to report alarm information and alert the fli...
