Reconstruction method of avionics interface design based on pilot's functional state

Abstract

The invention provides an avionics interface design reconfiguration method based on the pilot's functional state. Firstly, the data of the pilot's control state is obtained and formulated to obtain the input parameters of the CTL model, and the CTL model is used to evaluate the pilot's mental load. Then determine the basic information display units of the aircraft cockpit and divide them into levels. Combined with the information domain and the pilot's mental load, the K-means clustering algorithm is used to sort the importance levels of the information elements, and a new display information level is obtained. Finally, according to the visual attention division model, combined with the new display information level, the layout of the avionics interface is optimized. The present invention can fully consider the characteristics of human and machine agents, adjust the interface display elements in combination with the current flight operation and the pilot's functional state, and perform dynamic reconstruction of the avionics interface, so that the crew can obtain the required information with an appropriate visual load and improve The ability of the system to respond to emergencies and emergencies reduces the occurrence of unsafe incidents.

Description

technical field [0001] The invention belongs to the technical field of man-machine system design and simulation, and relates to an avionics interface design and reconstruction method based on the pilot's functional state. Background technique [0002] During the flight, the pilot needs to obtain information from the surrounding environment through the five sense organs, and manipulate the aircraft to complete the flight task according to the information, and most of this information comes from vision. Therefore, in the process of modern aircraft design, how to make the cockpit man-machine more reasonable The design of the interactive interface provides the pilots with the important information they need, so that the pilots can keep abreast of the flight status of the aircraft and make corresponding decisions, which is very important for improving flight safety.

Problems solved by technology

[0003] At present, scholars at home and abroad have carried out relevant research on the layout optimization of the human-computer interface, mainly focusing on the analysis of human physiological indicators, such as human eye data, EEG data, and breathing strength, to achieve the optimal interface layout. At present, most of the reconstruction methods of the man-machine interface are static, and the dynamic reconstruction of the man-machine interface has not been studied in depth.
