摘　　要：基于引信电子安全与解除保险装置所强调的安全性与可靠性设计思想,提出了一种备用解除保险模块的设计方案。该设计方案针对电子安全与解除保险装置中双逻辑控制芯片的组成结构,在实现原有逻辑控制功能的基础上,利用逻辑控制芯片上剩余的硬件资源,同时对电子开关电路进行优化,实现了在任何一片逻辑控制芯片失效的情况下,另一片芯片依靠备用逻辑控制模块仍能完成解除保险工作。使用FPGA芯片搭建功能验证电路,并通过测试软件对模块预设功能进行时序仿真验证。(运用马尔可夫理论,对所设计的备用保险模块的保险与解除保险逻辑进行分析验证,能够满足提高引信安全性的要求)该模块在保证原有电子安全与解除保险装置结构与功能的同时,提高了安全性与抗干扰能力,对电子安全系统的安全性冗余设计提供新的思路。Based on the safety and reliability design idea of fuze electronic safety and defusing devices,this paper proposes a design scheme of a standby defusing module.Aiming at the structure of the dual logic control chip in an electronic safety and defusing device,this design makes use of the remaining hardware resources on the logic control chip and optimizes the electronic switching circuit on the basis of realizing the original logic control function.In this way,in case of failure of any logic control chip,the other chip can still complete the removing work by relying on the standby logic control module.The FPGA chip is used to build the function verification circuit,and the timing simulation verification of the preset function of the module is carried out by testing the software.(Markov theory is used to verify the insurance and defusing logic of the designed standby insurance module,which can satisfy the requirements of improving the safety of the fuze.)This module not only guarantees the structure and function of the original electronic safety and defusing device,but also improves security and the anti-interference ability,which provides a new train of thoughts for the safety redundancy design of the electronic safety system.
