本文从容错技术的基本问题出发,针对平台罗经系统的特点,提出了有关基于系统总线冗余的平台罗经控制计算机系统设计及其实时故障测试方法,同时,较为详细地讨论了有关8086—2CPU的功能测试算法以及86/14SBC有关部件的测试方法。由于系统采用了交互式工作方法以及监视定时器,周期自检、重复运算等手段,使得整个容错系统具有较高的处理机利用率和实时故障处理能力。实验表明:该系统设计方案合理,是一种工程实用的计算机容错系统。
In this paper, starting from the basic problems of fault tolerant technology, aiming at the characteristics of platform compass system, a computer-based design of compass control system based on system bus redundancy and its real-time fault testing method are put forward. At the same time, the 8086-2CPU Function test algorithm and 86 / 14SBC related parts of the test method. As the system uses an interactive working method as well as monitoring timer, periodic self-test, repeated computing and other means, making the fault-tolerant system with high processor utilization and real-time fault handling capabilities. Experiments show that: The system design is reasonable, is a practical engineering computer fault-tolerant system.
