摘    要: 介绍一个分级式航空电子综合化仿真系统。该系统以航空电子综合化工程中一个分系统为仿真目标,由两层双余度1553B总线和MBI(multiplex bus interface)将AVS(Avionics simulator)、SSCU(subsystem control unit)、若干个EQS(equipment simulator)以及部分真实设备连成的三级分布式计算机系统。一个面向实时控制的分布式操作系统和相应的仿真软件分布在三级仿真器中;其中,分布式操作系统实现两级总线的衔接、通信控制、并行多任务管理、错误检测、故障处理和实时内存数据库管理,仿真软件模拟航空电子上层环境、操作员控制与显示、分系统各设备数据产生与接收数据处理以及信息处理应用任务。系统研制成功为工程化实现打下了技术基础并提供了一个实验环境。

关 键 词:仿真器  仿真系统  分级  航空电子综合化

Abstract:This paper presents a hierarchical avionics integrated simulation system. The object of simulation is a subsystem of the avionics integrated system. The system consists of AVS(avionics simulator)、 SSCU(subsystem control unit)、 several EQS(equipment simulator )and a few equipments with a 3-level distributed system architecture. These components are connected to 2-level two-redundant 1553B bus by the MBI(multiplex bus interface). A distributed operating system for realtime control and related simulation software are successfully developed and distributed in the 3-level simulator. The distributed operating system accomplishes connection of the 2-level bus, communication control, management of parallel tasks, error test, fault treatment and real-time memory data base management. The simulation software simulates a extermal environment of the subsystem, control &; display for operator, deta production and received data processing of each equipment in subsystem and application tasks for information processing. The system successfully developed, which will lay the foundation of engineering implementation, and provide an experimental environment.
Keywords:simulator  simulation system  hierarchic  avionics intrgration
