Abstract

The present invention discloses a multi-redundancy flight control computer real-time simulator and a system thereof. The technical solution of the invention mainly comprises a development monitoring host and a real-time simulation target machine. The developing monitoring host is used for establishing a multi-redundancy flight control computer model in Matlab / Simulink model design software, providing modeling support, executing graphic monitoring to the simulation operation process of established model, executing on-line modification to the parameter related with the operation of target processor code according to monitoring result, and storing the data of real-time simulation process. The real-time simulation target machine provides hardware support to the simulation operation of model established by the host. The invention also discloses the development monitoring host and the real-time simulation target machine. The technical scheme adopting the invention can provide environment support for the simulation development and operation of redundancy system.

Description

technical field [0001] The invention relates to the technical field of real-time simulation, in particular to a real-time simulation device and system for a redundant flight control computer. Background technique [0002] At present, the follow-up control layout technology has been widely used in aircraft design and manufacture. At the same time, the requirements for flight quality, maneuverability and flight range are also increasing, and the functions of flight control computers are becoming more and more complex. In order to meet the mission reliability and safety requirements of the flight control computer, redundancy technology is widely used in the design of the flight control computer. [0003] Redundancy design refers to a design method that requires two or more independent faults to cause a predetermined undesired working state. Redundancy design includes two key aspects: redundancy structure design and redundancy management design. [0004] The redundancy structu...
