Avionics system digitalized design verification system and method

Abstract

The invention relates to an aircraft avionics technology, in particular to an avionics system digitalized design verification system and a method. The system comprises a BCMP simulator, a MC simulator, an aircraft member simulator, a display device simulator and an OFP emulator. The invention comprises the following design steps such as POP design, system ICD design, each aircraft member simulator design and BCMP simulator design and the like, which can provide digitalized design tools for aircraft design stage, verify the top-level design without verification and modification at the uniting and adjustment stage after the aircraft members are developed, and greatly reduce cost and time of the design, verification and modification of the top-level design; moreover, pilots can intervene in advance in the prior period of model number design, thus evaluating the overall design of the avionics system and shortening model number development cycle.

Description

technical field [0001] The invention relates to aircraft avionics technology, in particular to a digital design verification system and method for an avionics system. Background technique [0002] At present, the avionics systems used in most advanced aircraft at home and abroad are all bus systems. The main functional components of the whole system can be divided into three categories: BCMP (including mission computer), display equipment (such as head-up display, bottom display, UFCP display), various aircraft component equipment (such as atmospheric engine, inertial navigation equipment, flight control equipment , fire control equipment, radar, etc.), each functional component communicates by 1553, 422, 429 buses. BCMP is the core control unit of the entire avionics system. Each aircraft component device realizes data scheduling and bus communication under the scheduling of BCMP, and each display device realizes screen switching and data display under the control of BCMP....

AI Technical Summary

Problems solved by technology

[0003] In the design process of the aircraft avionics system, on the one hand, since the components of the aircraft may come from different manufacturers, it may be difficult to connect the functional components during the system docking process; on the other hand, the aircraft designer and the aircraft The actual operator (pilot) of the aircraft is also a different person, so there may be situations where the operator of the aircraft is not used to the way the aircraft operates

At present, the general aircraft design units in China do not have effective digital design verification tools. For the top-level design, it is generally designed manually by designers. Problems cannot be discovered until the aircraft components are developed for joint debugging. Correction is costly and requires It consumes a lot of human, material and financial resources
