Large aircraft cockpit lighting environment simulation test system and method

Abstract

The invention provides a large aircraft cockpit lighting environment simulation test system. The test system comprises a flying process cockpit light environment analog simulation subsystem, a cockpit light environment real-time recording subsystem and a cockpit lighting vision work efficiency test subsystem. The light environment analog simulation subsystem can simulate all-weather static and dynamic state light environment outside a cockpit in the flying process, the light environment real-time recording subsystem can be utilized for collecting environment light changes of all areas in the cockpit, and finally, a lighting vision work efficiency test subsystem is applied to assessing brightness uniformity, contrast and readability of all the areas of the cockpit. Compared with the prior art, the light environment simulation capability is high, the capacity of simulating the daybreak, dusk, thunderstorm, cloud penetration, noon light and other extreme light environments is achieved, meanwhile, the system has the light environment field collection and record functions, and the design problem of cockpit lighting is solved. Through the simulation test system, the dependency of the cockpit vision efficiency design on the aircraft test flight process can be eliminated, and in the cockpit lighting design stage, the effect verification of the lighting environment can be completed.

Description

technical field [0001] The invention relates to an aircraft cockpit lighting technology, in particular to a large-scale aircraft cockpit lighting environment simulation evaluation system and an evaluation method thereof. Background technique [0002] The task functions of modern large aircraft are continuously strengthened. Correspondingly, the display information related to flight tasks has increased sharply. In order to meet the needs of information display, a large number of information display devices (integrated electronic displays, signal lights, light guide plates, etc.) are integrated in the cockpit. During the voyage, due to the influence of dynamic and static light environment changes such as high-altitude multi-angle high-intensity light irradiation, glare reflected by clouds, direct horizontal light at dawn / dusk, strong light strobe during thunderstorms, etc., the information displayed on the display device may be difficult to identify or not clear. In order to e...

AI Technical Summary

Problems solved by technology

However, the light environment simulation subsystem can only simulate uniform ambient light, and does not have the ability to simulate extreme light environments such as dawn, cloud penetration, cloud reflection, high noon light, dusk, and thunderstorms, and cannot record the on-site light environment during evaluation. System design problem, due to the lack of light environment data, it is not easy to solve the design problem
