A Novel Method of Avionics Circuit Simulation

As the drastic advancement in the computer and software technologies, simulation of avionics system is gradually moving towards the use of modular avionics for an important component of the aero plane simulator. Traditionally, avionics simulators use unrelated identifier of system to identify the different fault information and establish various operational functions without providing the circuit structure, this potentially leading to the simulation modular being implemented irrelevantly, which would not conducive to the cosmically systems realization. Basis on the characteristics of the avionics system, an avionics circuit model is designed, and it modeled avionics circuit structure and their connection according as the circuit schematic, application of A* algorithm and recursive iterative algorithm achieved circuit depth-traversing. It supports the multimeter to measure the circuit voltage, resistance and current, and estimating the value is right or not to find the fault point and replace the components. The simulation of the avionics system both simulated the operation state of aircraft various subsystems and realized the function of fault diagnosis.
