摘要
全电子电码化执行单元的主系断电会导致外部发送器移频信号中断,为解决该问题,基于既有电码化切系逻辑,提出一种快速升主的解决方案,从切系逻辑方案优化、双主分析、软件实现、功能测试、存在问题等方面做详细介绍。该方案能缩短主系断电备系升主的时间,解决发送器移频信号中断的问题。
Main system power outage of the fully electronic coding execution unit can cause external shift-frequency signal interruption,to solve this problem,based on the existing coding switching logic,this article proposes a fast solution for becoming the main system,which provides a detailed introduction of the optimization of switching logic scheme,dual master analysis,software implementation,functional testing,and existing problems.In the event of main system power outage,this solution can shorten the time it takes for the backup system to become the main system,solve the problem of external shift-frequency signal interruption.
