Small Caliber Ammunition Fuse Remote Arming Control Circuit Design

为实现引信安全保险系统具有远距离解除保险状态的功能,分析小口径弹药引信结构特征和发射内外弹道环境,结合几类不同环境探测传感器的适用特点与范围,选择基于地磁环境信息的磁阻传感器,并针对磁阻传感器芯片的使用特性,设计了芯片的复位开关电路。弹丸发射出炮口后,磁阻传感器输出微弱电压信号,经信号调理后作为延时控制电路的控制开关指令信息。延时控制电路是实现远距离解除保险状态的关键部件,控制电路通过检测信息并延时后,输出电压信号指令给火工品拔销器,拔销器执行隔爆板限位销的拔销动作,解除保险系统的最后一道保险,实现了引信远距离解除保险的目的。

In order to achieve fuse security system with remote arming function, by analysis of small-caliber ammunition fuse structural features and ballistic trajectory environment, combined with the applicable characteristics and scope of several different types of environmental detection sensors, magneto resistive sensor based on the geomagnetic environment information and use characteristics of the magneto resistive sensor chip to design chip reset switch circuit. The magneto resistive sensor output weak voltage signal the projectile muzzle emitted after the instruction information as a delay control circuit controls the switch after signal conditioning. Delay control circuit is a key component of remote arming state, the detected information and delay control circuitry, the output voltage signal instructions to the EED pin puller pin puller implementation of the explosion-proof plate stopper pin pull off action, the lifting of the insurance system last line of insurance, to achieve the purpose of the fuse remote arming.
