Description

Technical Field

[0001] The utility model relates to the technical field of cockpit dimming control systems, in particular to a cockpit instrument panel lighting brightness adjustment system based on eye movement sight capture. Background Art

[0002] The main function of the existing aircraft dashboard lighting system in the cockpit human-machine interface is to provide lighting and information indication, and provide auxiliary support for aircraft operations. The aircraft dashboard lighting system mainly creates a good visual environment suitable for pilots to operate through the overall lighting of the light guide plate, general lighting in the cockpit, total dimming and light test functions, and control devices that control other system functions. At the same time, it ensures that the pilot can accurately and clearly interpret all displayed information under various illumination environments, effectively reducing the pilot's visual fatigue and ensuring flight safety.

[0003] At present, the aircraft instrument panel lighting system mainly adopts a manual double-layered knob to achieve the lighting dimming of the instrument panel floodlight.

[0004] During night flights, especially half an hour before landing, pilots usually adjust all lights in the cockpit to the lowest acceptable brightness to ensure night vision during approach and landing. The existing aircraft dashboard lighting system and lighting dimming method have the following problems:

[0005] 1. The instrument panel floodlights are kept at low brightness or turned off. When the pilot needs to observe the instrument panel readings, each dimming operation requires manual operation, which increases the pilot's operating burden;

[0006] 2. The brightness of the instrument panel floodlight is too high, and the difference between the brightness of the instrument panel and the external environment is too large, which will cause the pilot's pupil to shrink and affect the pilot's vision;

[0007] 3. The brightness of the dashboard floodlight is too high. The dashboard floodlight will be reflected by the nearby interior, and the reflection will affect the pilot's vision.

[0008] Eye tracking technology usually refers to a technology used to record and measure eye movements. It relies on eye trackers to collect eye movement data. According to the usage scenarios, modern eye trackers can be mainly divided into two types: screen-based eye trackers and wearable eye trackers. In the existing technology, there is no feasible technical solution to achieve lighting dimming of dashboard floodlights based on eye tracking technology, and it is necessary to further study this.

[0009] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.
