摘要
为了提高某高原无人值守雷达中波控系统的可靠性,必须对波控计算机进行双机热备份设计。介绍了利用两块嵌入式PC104模块设计的可用于恶劣环境下的双机控制系统,并就双机之间如何实现故障检测、自动切换、系统重构进行了详细的分析,同时对单板双机的可靠性进行了研究分析。
The duplex hot-backup system design is very important to improve the reliability of beam steering system of certain unattended radar in plateau area.This paper introduces two dual-computer system using two embedded PC104 modules used in adverse environments,and explains how to realize the fault location,automatic switching and system reconfiguration between two dual-computer system.This paper also studies and analyses the reliability of dual-computer system on board.
