摘要
结合实际工程中普遍存在的电磁干扰现象,就硬件抗干扰设计进行了总结,分析了电磁干扰源、干扰的传输途径及干扰产生的后果。主要从抑制干扰源、切断干扰传输途径两方面出发,提出了嵌入式导弹测控系统硬件抗干扰设计思想。详细归纳了嵌入式导弹测控系统电路中供电系统、接地、信号传输通道、空间电磁场以及印制电路板的总体布局与走线等方面的抗干扰设计方法,给出了一种恢复受干扰系统的专用复位电路。
Confronted the universal EMI in practical projects,the hardware antiinterference design are summarized.EMI resources,approaches and aftereffects are analyzed.From restraining EMI resources and cutting off transmitting channels.The design thought of anti-interference in embedded test-control system hardware of missile is presented.The design of power supply,signal transmitting channels,space electromagnetic field and holistic layout in PCB design are summarized in details.The circuit to reset interfered system is presented.
