单片机系统在核电磁脉冲辐照下的效应研究
Study on irradiation effects of nucleus electromagnetic pulse on single chip computer system
-
摘要: 核电磁脉冲（NEMP）、雷电电磁脉冲（LEMP）和高功率微波（HPM）等强电磁脉冲对单片机系统具有很强的干扰和破坏作用。为研究它们对单片机系统的各种效应，利用GTEM室产生的核电磁脉冲，对单片机系统进行了辐照效应实验。实验表明，单片机系统在强电磁脉冲作用下，会出现“死机”、重启动、通讯出错等现象。基于实验，讨论了单片机系统的各种效应产生的原因。Abstract: Intense electromagnetic pulse，namely nucleus electromagnetic pulse(NEMP)， lightning electromagnetic pulse(LEMP) and high power microwave(HPM), can disturb and destroy the single chip computer system. To study this issue, we made irradiation experiments by NEMPs generated by gigahertz transversal electromagnetic(GTEM) Cell. The experiments show that shutdown, restarting, communication errors of the single chip microcomputer system would occur when it was irradiated by the NEMPs. Based on the experiments, the cause on the effects on the single chip microcomputer system is discused.
