一种基于VxWorks的飞行仿真实时管理系统

结合北京航空航天大学自动控制系开发的某大型工程飞行模拟器系统，介绍了一种基于嵌入式实时操作系统VxWorks和多处理机系统的仿真系统结构及其开发环境。首先介绍了VxWorks的特点。然后介绍了飞行仿真系统的总体结构及管理系统的主要功能。最后讨论了实时管理系统实现中的关键问题，包括多任务管理在不同开发环境下的实现以及分布式仿真系统的实时数据通讯等。

A Real-time Management System of Flight Simulation Based on VxWorks

With a large engineering flight simulation system developed by the Dept. of Automation Control at Beijing University of Aeronautics and Astronautics, this paper introduces a structure and development environment of simulation system, which is based on embedded RTOS VxWorks and multiprocessor system. Characteristics of VxWorks have been introduced. Structure of the whole flight simulation system and main function of the management system have been described. Then some key techniques in realization of the management system have been discussed, including multitask management in different development environment and real-time communication of distributed simulation system.
