Description

A unit failure status monitoring system based on contact sensor Technical Field

[0001] The present invention belongs to the field of cockpit flight crew health status monitoring, and in particular relates to a crew disability status monitoring system based on a contact sensor. Background Art

[0002] Large commercial civil airliners require at least two pilots to operate. With the continuous development of the aviation industry, the proportion of aircraft maintenance and fuel costs in airline operating costs is gradually decreasing, while the proportion of crew costs is gradually increasing, which has an increasingly greater impact on the economic profitability of airlines. According to the International Air Transport Association (IATA), air transport volume is expected to double, and the industry will face a pilot shortage. Therefore, to control crew costs and address the pilot shortage, the aviation industry has conducted extensive technical research and future planning for intelligent flight technology for commercial aircraft, including single pilot operation (SPO), autonomous taxiing, takeoff and landing (ATTOL), Airbus's DragonFly project, NASA's "Aviation Strategy Implementation Plan" and EASA's "Artificial Intelligence Roadmap", building a vision for future intelligent flight for commercial aircraft.

[0003] However, if single-pilot flight is to be achieved through advanced airborne automation equipment or air-ground collaborative operation mode, the workload and driving pressure of a single pilot should not be higher than that of the current two-person crew mode. Therefore, how to reasonably and efficiently monitor the pilot's status, including fatigue, behavior, psychology, emotions, workload and disability, will not only help pilots fly safely, but also help promote commercial aircraft into the era of intelligent flight.

[0004] Pilot incapacitation refers to a decrease in physical fitness to a level that could endanger flight safety. Depending on the severity, it can be categorized as either total or partial incapacitation. When a pilot is incapacitated, their flight control abilities will decline to varying degrees, either noticeably or subtly. In severe cases, this can lead to a flight accident. According to the "1% rule," the fatal accident rate due to a single pilot incapacitation should not exceed 1 in 10. -9 hours, for a two-pilot aircraft, the risk of pilot incapacitation is no more than 1 in 10 -6 Therefore, for single-pilot flight modes, a reasonable disability status monitoring method must be adopted to reduce the risk rate caused by pilot incapacitation to the risk level of two-pilot flight. This is a key technology that urgently needs to be solved for future intelligent flight of aircraft.

[0031] S4: If the AI ​​crew disability status recognition model determines that the crew is disabled, visual and auditory warning information will be issued in the status warning module, and the pilot secondary status confirmation page will pop up on the display unit. The pilot's voice information and touch feedback information will be received in real time according to the pilot's ability to reconfirm the pilot's status. If the pilot's status is normal, the visual and auditory warning information will be eliminated.
