Task demand-based airborne system design method

Abstract

The invention discloses a task demand-based airborne system design method. The task demand-based airborne system design method comprises the following steps of 1: performing modeling analysis according to overall task demands, and according to an obtained corresponding view analysis information interaction relationship, obtaining an aircraft level task activity view; 2: decomposing out system level task activity demands, and building activity view models of the system level task activity demands, wherein the activity view models comprise system level function view models and system level dataflow views; 3: according to the system level function view models and the system level data flow views, obtaining system level function requirements and obtaining system level capability demands; 4: according to the system level capability demands, obtaining system level system functions; and 5: associating the system level capability demands in the aircraft level task activity view with aircraftlevel system functions, and establishing a tracking mapping matrix between the system level capability demands and the aircraft level system functions.

Description

technical field [0001] The invention relates to the technical field of aircraft recording systems, in particular to an airborne system design method based on mission requirements. Background technique [0002] According to the functions, the aircraft can be divided into four levels: aircraft level, system level, equipment level and component level. The functions of each level are realized by multiple lower-level functional components. The system is an important part of the aircraft, and the combat performance of the aircraft is closely related to the system. [0003] Airborne systems can be divided into avionics systems and functional systems. The function of the avionics system is to complete the functions related to the flight mission, such as navigation, atmospheric data, human-machine interface, etc. The function of the functional system is to enable flight and provide public facilities required by flight missions, usually referring to safety-critical systems related t...

Problems solved by technology

However, this design method often ignores that the aircraft itself is also a system in the equipment system. If the comprehensive capabilities that the equipment system should have are not considered, the matching relationship between aircraft capabilities cannot be guaranteed, and the seamless connection between aircraft requirements and system design cannot be guaranteed.
