Embodiment Construction

[0046] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0047] Step 1: Obtain the operation sequence and the operation attributes of each operation within the specified time f when the pilot performs the flight mission.

[0048] (1) Record the pilot's operation sequence within the specified time period in the order of occurrence, such as: nose up operation, throttle increase operation, etc.

[0049] (2) The attributes of each operation include information processing type l, time range d, attention requirement ratio a, and information domain I. The calculation method of each attribute is as follows:

[0050] a) Information processing typel

[0051] The SRK (Skill-Rule-Knowledge) framework is used to quantify each operation. The pilot's operations are divided into three categories, skill-based (no need for analysis and synthesis, conditioned reflex), rule-based (less analysis and synthesis is required) and knowledge-...

Abstract

The invention relates to a dynamic function distribution method based on a brain load model and fuzzy logic. According to the method, advantages of all constituting individuals are used sufficiently, system resources are distributed best, and whole system performance is optimized. Due to the dynamic function distribution, the role of a flight unit in a system is more flexible, the scene consciousness of the flight unit can be enhanced, work satisfaction is improved, technology degradation is avoided, the robustness of the system is enhanced, and safety of the flight process is improved.

Description

technical field [0001] The invention relates to an automatic design technology of a civil aircraft cockpit, in particular to a dynamic function allocation method based on a mental load model and fuzzy logic. Background technique [0002] The aircraft cockpit consists of a complex human-machine system consisting of the flight crew, automation subsystems, and the interactive interfaces between them. The flight crew consists of one or more pilots in the cockpit. The automation subsystem refers to the machine that can complete certain functions, including automatic flight control system, automatic throttle, flight management computer, automatic warning system, etc. In order to achieve the predetermined goals and complete the predetermined tasks, and at the same time enable the human and machine to fully play their respective roles and work in harmony, it is necessary to reasonably assign the functions or tasks to be performed to the flight crew or the automation system. This pr...
