Most of the current semi - physical simulators of the avionic system consist of special software and hardware , which results in the necessity to develop simulators independently for different avionic devices . simultaneously , according to the requirement of the software engineering , software must need to be strictly tested after developed or modified . this will consume much energy and time , and makes the software hard to be maintained 当前的航电系统半实物仿真器多是使用专用的硬件设备搭配专用的仿真软件来实现的,这种专用性就造成了需要针对不同航电设备单独开发仿真器的问题,同时按照软件工程的要求,软件的开发以及修改都要经过严格的测试,这就使得仿真系统的开发耗费大量的精力和时间,同时使得仿真软件难以维护。
The dissertation carefully analyzes the as1773 bus system structure and utilizes the emulation software opnet to establish as1773 system emulation model with the help of the avionic system . the dissertation analyzed the various performance indexes of the synchronic and diachronic messages of the system under the circumstance of the different load 本文详细分析了as1773总线系统结构,结合航空电子系统,运用仿真软件opnet建立了as1773的系统仿真模型,分析了系统在不同负载情况下传输同步消息和异步消息的各种性能指标。
Abstract : the paper introduces the acoreos ( avionic core real - time operating system ) which has satisfy new generation avionic electro system demand for , has data synthesize , has model fault tolerance and reconfiguration . the acoreos consist of three main function levels . the reconfiguration problem is emphasized . much work has been gone on fault processing 文摘:主要阐述了满足新一代航空电子系统中核心数据综合处理要求的实时操作系统；概述了系统软件的三个主要层次的总体结构；着重论述了重构处理机的问题；并详细讨论了处理机容错重构处理的实施过程。
