摘要
研究了调度集中系统中双机热备的实现方案.给出了故障定义原则,详细讨论了双机之间的基本倒机原则及倒机优先级,并进一步给出了双机热备机制的工作原理流程图,列出了双机热备机制中的状态转移.本文提出的双机热备实现方案已在FZj-CTC型分散自律调度集中系统中得到了应用,应用结果表明,本方案切实可用.对于高可靠的应用要求,本文具有良好的借鉴作用.
It is researched that the realizable scheme of the hot standby for Centralized Traffic Control （CTC） in this article. The principle of failure level is given out, and the basic principle and priority of failover are discussed in detail. The sketch of working principle of hot standby is designed and shift of working status is analyzed. The scheme given out in the paper has been applied in centralized traffie control of the type FZj-CTC which has been proven practical and applicable to the work. It can be used for reference in high reliability application.
