引信电子安全系统解除保险逻辑分析

提出在引信电子安全系统中用3个环境激励控制3个保险件的5种解除保险逻辑设计.采用马尔科夫理论对其进行建模和分析,对5种解除保险逻辑的引信电子安全系统的安全性进行了比较、分析和排序.得出系统中采用3个独立保险件加两个时间窗,且同时闭合的解除保险逻辑模式的安全性最高.通过与两个环境激励的机电安全系统的安全性比较表明,引信电子安全系统的安全性比机电安全系统高.

Analysis on the Arming Logic of Fuze Electronic Safety and Arming

Five kinds of arming logic models with three independent safe devices controlling three environmental stimuluses are proposed.The context adopted Markov theory to set up different arming logical models and analyzed them.In theory,for five models of electronic safe and arming(ESA),it attained the highest safety with three safe devices and added two time windows and closed simultaneously.A comparison is made with the safety of mechatronic safety and arming adopting two independent environmental stimuluses,the inherent safety of ESA is found to be higher.
