Scotopic vision protection system for cockpit pilot under quiet and dark flight state of aircraft and luminous environment monitoring method

Abstract

The invention relates to a scotopic vision protection system for a cockpit pilot under a quiet and dark flight state of an aircraft and a luminous environment monitoring method. The scotopic vision protection system consists of an illuminance/brightness monitoring, display and control device, an illuminance/brightness/spectrum monitoring instrument, a mesopic vision/scotopic vision correction database, a scotopic adaptation protection spectrum system and a scotopic adaptation spectrum control database; when the aircraft is in the quiet and dark flight state, the illuminance/brightness is detected, a corresponding spectrum is tested, if the measured illuminance/brightness is positioned in a photopic vision range, the illuminance/brightness is not corrected, and if the illuminance/brightness is positioned in a mesopic vision brightness range, the illuminance/brightness is corrected by a mesopic vision model database and correct illuminance/brightness information is acquired; and when the measured illuminance/brightness and spectrum information is input to the monitoring and display device, the device controls the scotopic adaptation protection spectrum system to compensate the illuminance/brightness information, and the output spectrum distribution is controlled by the scotopic adaptation spectrum control database. The scotopic vision protection system effectively protects the scotopic vision of the pilot under the condition of finishing flight control vision tasks.

Description

technical field [0001] The invention relates to the field of optical detection and biological effects of scotopic vision, in particular to a scotopic vision protection system for cockpit pilots and a light environment monitoring method in the quiet and dark flight state of an aircraft. Background technique [0002] The lighting of the aircraft cockpit must meet the requirements of night flight. It not only ensures that pilots can quickly and accurately observe various instrument displays during night flights, but also protects the night vision for observing dark targets outside the cabin from being damaged. The lighting in the cockpit of an aircraft is in the range of mesopic vision. [0003] According to the regulations of the International Institute of Illumination (CIE), the brightness level is several cd / m 2 When above, the work of the cone cells plays a major role. At this time, the pupil of the human eye is small, which can distinguish the details of things and also ...
