cni modeling system

Abstract

The present invention proposes a CNI modeling system, aiming to provide a modeling system that supports the static physical environment of the CNI system, dynamic processing commands and operating procedures under the condition that the hardware environment does not exist, and the present invention is realized through the following technical solutions: The integrated data routing module accesses real physical devices through Ethernet; the physical resource modeling module provides static information modeling of the physical device environment of nodes, communication links, and configuration attributes; the dynamic processing modeling module provides command processing action template code generation functions, Users add specific action processing function codes according to requirements, and build a command processing action library; the dynamic and static association module of the model associates the nodes in the physical resource model with the dynamic simulation processing commands, and establishes the dynamic and static processing information association relationship; the system dynamic operation simulation module will The process model file is generated by the CNI system state change process set by the user, and the dynamic operation simulation of the system equipment is realized through the process analysis driving engine to execute the model file.

Description

technical field [0001] The invention relates to a modeling system mainly used in the field of avionics communication and navigation identification (CNI), especially applicable to the field of full-process dynamic simulation testing of CNI system integrators and function waveform providers in a semi-physical environment. Background technique [0002] Communication, Navigation and Identification (CNI subsystem) is an important part of the avionics system. As an important subsystem of the avionics system, the CNI subsystem involves data processing, signal processing, radio frequency front-end processing and other components. It has many integrated functions and a complex system structure. It needs to realize data and voice communication, friend-or-foe identification, flight and landing navigation, etc. . There are as many as dozens of sensor waveform functions integrated in the comprehensive signal processor adopted by the new generation of CNI system in China. The integrated...
