双冗余飞行控制计算机系统设计与实现

Design and implementation of dual-redundancy flight control computer system

采用冗余技术是提高系统可靠性的重要手段。结合工程实践,详细介绍了一种双冗余飞行控制计算机系统的设计思路与方法。首先,描述系统设计结构和工作原理,然后,重点讲述如何在嵌入式实时操作系统VxW orks环境下进行多任务算法设计的要点。该冗余系统能有效地提高安全可靠性和任务可靠性,并具有良好的实时性和实用性的特点。

Rdundancy technology is very important to improve the reliability of system. A kind of new method of dual redundancy flight control computer system was presented in detail. First, the system architecture and the basic principle working were introduced in brief. Second, how to write multiple-task arithmetic in the embedded real-time operating system of VxWorks was introduced. This dual-redundancy system can improve safety reliability and task reliability effectively, and by using this method, the designed system becomes good real-time and practicable.
