Distributed Real-time Synthetic Simulation Method for Avionics System

Abstract

The invention relates to a distributed-type real-time comprehensive simulation method of an avionics system. The distributed-type real-time comprehensive simulation method of the avionics system comprises the following steps that code templates of an excitation model, a device model and a monitoring model are defined, and a simulation kernel is defined; according to the defined code templates, the excitation model, the device model and the monitoring model are generated, wherein the excitation model, the device model and the monitoring model can be simulated; a simulation excitation source is configured according to simulation requirements, excitation signals are generated, and the excitation model reads the excitation signals in real time so as to complete signal refreshing; according to a signal transmission relation described in an interface control file, a plurality of ports of the device model, the excitation model and the monitoring model are connected, the device model, the excitation model and the monitoring model are dispatched by the simulation kernel on the basis of a unified time axis, signal transmission among the models is carried out, and simulation of the avionics system is achieved; a simulation result is processed and displayed in real time through a simulation monitoring device. The simulation method can be used for achieving real-time, dynamic, multidisciplinary and high-fidelity comprehensive simulation of the avionics system.

Description

technical field [0001] The invention belongs to the technical field of avionics, relates to simulation analysis of avionics systems, and in particular to a distributed real-time comprehensive simulation method of avionics systems. Background technique [0002] The rapid development of electronic technology and network technology has promoted the upgrading of avionics systems. The new generation of integrated avionics systems based on IMA and DIMA architectures has a complex architecture and a short development cycle, so it is particularly important to carry out simulation verification and iteration of system design schemes as soon as possible. Discovering system problems through simulation at the early stage of system development, especially design flaws and incompatibilities at the signal level of avionics systems, can avoid high costs and schedule delays in the later stages of the project and even during system operation. However, the existing simulation methods for avion...
