| 摘 要： | 为保证运载火箭在零窗口发射,提出了一种基于IRIG-B码(以下简称B码) 的运载火箭测发流程自动执行的软件设计方法,以确保点火前10min至点火之间的各系统流程的同步。本方案通过UDP网络接收B码的时间,并通过五取三冗余算法,以更新本地的B码时间。随后,再根据预设的点火时间及冗余后的B码时间,计算倒计时,以控制口令流程自动执行。

| Abstract: | To guarantee the launching of the rocket in zero window, this article designs a software method based on IRIG-B code for testing and launching (hereinafter referred to B code for short) for rocket, to ensure the system process synchronized from 10 minute before the ignition to ignition. We can use the receiving time of B code got by UDP network to update the local B code time through redundancy algorithm. With the newest local B code time and the default set fire time, we can calculate the countdown to execute the process automatically. |
