基于三个环境信号的引信电子安全系统安全性分析

解除保险逻辑的设计是保证电子安全系统高安全性的重要步骤。本文针对实际设计中引信电子安全系统可能采用的五种解除保险逻辑模式安全性进行了分析、比较和排序。指出电子安全系统的三个独立的电子开关采用加两个时间窗、且同时闭合的控制模式是这五种之中安全性最高的。最后与采用两个环境激励的机电安全系统的安全性进行了比较

AN ANALYSIS ON THE SAFETY OF ELECTRONIC SAFETY AND ARMING BASED ON THREE ENVIRONMENTAL SIGNALS

Design for logical arming is an important procedure to assure a high safety in electronic safety and arming(ESA).This paper analyses and compares five different logical arming models.Their difference is apparent.In theory,for the five models of electronic safety and arming(ESA),the highest degree of safety is attained through control with three electronic switches added by two time windows closed simultaneously. A comparison is given with the safety provided by a mechanical or mech-electronic arming adopting two independent environmental signals.
