Design of modular communication navigation recognition system applied to certain type of helicopter

文章针对直升机平台设计了通信系统,基于集成化、模块化架构的设计思路并通过系统综合化接口对各功能线程进行集中管理。其中,采用资源综合方法对系统控制、管理、数据处理及供电等与特定传感器功能耦合度较低的电路进行通用化、模块化设计;采用功能综合方法对系统内特定传感器功能紧密相关的射频信道、信号处理等电路进行小型化、模块化设计。文章开创性地建立了基于模块的集成化通信导航识别系统体系架构,解决了工程实践中的诸多难题(如重量、电磁兼容性、可靠性等),实现了通信导航识别(CNI)系统从联合式架构向模块化小型化架构的跨越,对我国航空电子系统装备的升级换代与航空电子技术的发展具有重要意义。

This article designs a communication system for helicopter platforms,based on an integrated and modular architecture design concept,and centrally manages various functional threads through a comprehensive system interface.Among them,the resource integration method is used to design circuits with low coupling to specific sensor functions,such as system control,management,data processing,and power supply,in a universal and modular manner.Adopting a comprehensive functional approach to miniaturize and modularize RF channels,signal processing circuits,and other circuits closely related to specific sensor functions within the system.This article innovatively establishes a modular integrated communication and navigation identification system architecture,which solves many problems in engineering practice(such as weight,electromagnetic compatibility,reliability,etc.),and realizes the leap of Communication And Navigation Identification(CNI)system from a joint architecture to a modular and miniaturized architecture.It is of great significance for the upgrading and development of China’s aviation electronic system equipment and aviation electronic technology.
