Abstract
Description
Technical Field
[0001] This application belongs to the field of alarm system inspection and design technology, specifically relating to a self-testing method for an aircraft cockpit alarm system. Background Technology
[0002] The quality of an aircraft's cockpit warning system directly impacts flight safety and mission completion. Although designers fully consider the reliability of the warning system during the design process, pilots still need to confirm the system's proper functioning before each takeoff and landing, and during certain parts of the flight. Therefore, a self-check is still required for the warning system.
[0003] Currently, the self-test technology of aircraft cockpit alarm systems only relies on lighting self-tests to check the condition of alarm lights. There is a lack of effective means to check other display alarms and auditory alarms. As a result, in some cases, the alarm system has failed to function properly, and the pilots cannot be aware of it in time, which can lead to catastrophic accidents.
[0004] In view of the aforementioned technical deficiencies, this application is hereby filed. Summary of the Invention
[0005] The purpose of this application is to provide a self-testing method for an aircraft cockpit warning system to overcome or mitigate at least one of the known technical defects.
[0006] The technical solution of this application is:
[0007] A self-test method for an aircraft cockpit alarm system includes setting an "alarm self-test" operation item on the alarm screen of the aircraft cockpit display;
[0008] When operating the "Alarm Self-Check" operation item on the ground, the alarm system performs a self-check of the lighting alarm system, display alarm system, and sound alarm system;
[0009] When operating the "Alarm Self-Check" option in the air, the alarm system will only perform a self-check of the light alarm system;
[0010] If the alarm system performs a self-check by operating the "Alarm Self-Check" operation, and is not operated again within 12-28 seconds, the alarm system will exit the self-check and resume normal operation.
[0011] If the "Alarm Self-Check" operation is performed again during the alarm system's self-check, the alarm system will exit the self-check and resume normal operation.
[0012] If a new high-level danger alarm appears during the alarm system's self-test, the alarm system will exit the self-test and resume normal operation.
[0013] According to at least one embodiment of this application, in the above-described aircraft cockpit alarm system self-test method, the alarm self-test command is distributed by the aircraft alarm integrated management system to each visual and auditory terminal.
[0014] According to at least one embodiment of this application, in the above-described aircraft cockpit alarm system self-test method, when the ground operator performs the "alarm self-test" operation, the alarm system performs a self-test:
[0015] The lighting alarm system pauses the current lighting alarm, enters self-test mode, and turns on all the alarm lights in the cabin;
[0016] The head-up display of the alarm system pauses the current alarm character display and enters self-test mode. It then sequentially flashes "Level 1 Test", "Level 2 Test", "Level 3 Test" and "Level 4 Test" for 3-7 seconds each, depending on the cockpit layout of each aircraft model. The main alarm screen pauses normal alarm display and enters self-test mode, displaying the alarm lists for "Level 1 Test", "Level 2 Test", "Level 3 Test" and "Level 4 Test".
[0017] The audio alarm system pauses the current audio alarm and enters self-test mode, sequentially playing the "Level 1 Test" voice twice, "Level 2 Test" twice, "Level 3 Test" twice, and "Level 4 Test" alarm prompt tones twice.
[0018] According to at least one embodiment of this application, in the above-described aircraft cockpit alarm system self-test method, the "alarm self-test" operation item is activated in-flight, and the alarm system performs a self-test when:
[0019] The lighting alarm system pauses the current lighting alarm, enters self-test mode, and illuminates all the alarm lights in the cabin.
[0020] According to at least one embodiment of this application, in the above-described aircraft cockpit alarm system self-test method, after the alarm system exits the self-test and resumes normal operation, it issues alarms based on the currently existing actual alarm information.
[0021] This application has at least the following beneficial technical effects:
[0022] This paper provides a self-testing method for an aircraft cockpit alarm system. By using the "one source, multiple terminals, and separate testing method", the system can perform self-testing on all levels and types of alarms on the aircraft. This can improve the pilot's ability to perceive the working status of the aircraft cockpit alarm system before each takeoff and landing and during some flight missions, enabling the pilot to grasp the current working status of the aircraft alarm system in a timely manner. Attached Figure Description
[0023] Figure 1 This is a schematic diagram of the design of the self-testing method for the aircraft cockpit alarm system provided in the embodiments of this application.
[0024] To better illustrate this embodiment, some content in the accompanying drawings may be omitted, enlarged, or reduced. They are for illustrative purposes only and should not be construed as limiting the scope of this application. Detailed Implementation
[0025] To make the technical solution and advantages of this application clearer, the technical solution of this application will be described in a clearer and more complete manner below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, and other related parts can be referred to the general design.
[0026] Furthermore, unless otherwise defined, the technical or scientific terms used in this application description shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The word "comprising" as used in this application description indicates that the concept preceding the word encompasses the concepts listed following the word and their equivalents, without excluding other related concepts.
[0027] To improve pilots' awareness of the operational status of the aircraft cockpit warning system before each takeoff and landing and during some flight missions, embodiments of this application provide a self-test method for the aircraft cockpit warning system, such as... Figure 1 As shown, the "one source, multiple terminals inspection method" is used to perform self-inspection on all levels and types of alarms on the aircraft, enabling pilots to keep abreast of the current working status of the aircraft alarm system.
[0028] The aircraft cockpit display alarm screen has an "alarm self-test" option. During ground operations, the alarm system performs self-tests on the light alarm system, display alarm system, and sound alarm system. During in-flight operations, the alarm system only performs a self-test on the light alarm system. The alarm self-test command is distributed by the aircraft alarm integrated management system to each visual and auditory terminal.
[0029] The specific logic design for the self-test of the aircraft cockpit alarm system is as follows:
[0030] The "Alarm Self-Check" operation item in ground operations refers to the alarm system performing a self-check:
[0031] The lighting alarm system pauses the current lighting alarm, enters self-test mode, and illuminates all the alarm lights in the cabin.
[0032] The head-up display of the alarm system pauses the current alarm character display and enters self-test mode. It then sequentially flashes "Level 1 Test", "Level 2 Test", "Level 3 Test" and "Level 4 Test" for 3-7 seconds each, depending on the cockpit layout of each aircraft model. The main alarm screen pauses normal alarm display and enters self-test mode, displaying the alarm lists for "Level 1 Test", "Level 2 Test", "Level 3 Test" and "Level 4 Test".
[0033] The audio alarm system pauses the current audio alarm and enters self-test mode, sequentially playing the "Level 1 Test" voice twice, "Level 2 Test" twice, "Level 3 Test" twice, and "Level 4 Test" alarm prompt tones twice.
[0034] When the alarm system performs a self-check, the following steps are performed during the over-the-air operation of the "Alarm Self-Check" item:
[0035] The lighting alarm system pauses the current lighting alarm, enters self-test mode, and illuminates all the alarm lights in the cabin.
[0036] If the "Alarm Self-Check" operation is performed and the alarm system performs a self-check, and the "Alarm Self-Check" operation is not performed again within 12-28 seconds, the alarm system will exit the self-check and resume normal operation.
[0037] If the "Alarm Self-Check" operation is performed again during the alarm system's self-check, the alarm system will exit the self-check and resume normal operation.
[0038] If a new Level 1 or Level 2 high-level danger alarm appears during the alarm system's self-test, the alarm system will exit the self-test, resume normal operation, and issue the corresponding alarm.
[0039] After the alarm system exits self-test and resumes normal operation, it will issue alarms based on the actual alarm information that currently exists.
[0040] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
