CNI (Communication, Navigation and Identification) modeling system

Abstract

The invention puts forward a CNI (Communication, Navigation and Identification) modeling system, and aims to provide a modeling system which supports a CNI system statistic physical environment, a dynamic processing command and an operation process when a hardware environment is not provided with conditions. The system is realized through the following technical scheme: an integrated data routingmodule is accessed into real physical equipment through the Ethernet; a physical resource modeling module provides the physical equipment environment static information modeling of nodes, communication links and configuration attributes; a dynamic processing modeling module provides a command processing action template code generation function, a user adds a specific action processing function code according to requirements to construct a command processing action library; a model static and dynamic association module associates nodes in the physical resource model with a dynamic simulation processing command to establish a dynamic and static processing information association relationship; and a system dynamic operation simulation module generates a process model file by a CNI system state change process set by the user, and the model file is executed through a process analysis driving engine to realize the dynamic operation simulation of the system equipment.

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...
