【摘要】 本文以GSM/GPS车裁定位系统终端的可靠性设计为例,研究了基于嵌入式MCU应用系统的可靠生接口技术,重点讨论车载通信终端的抗干扰设计。内容涉及嵌入式MCU应用系统接口EMI特点,系统可靠性设计原则,汽车电磁环境分析与接口特点,车载通信终端的抗干扰设计。 为设计出可靠稳定的车载通信终端,首先分析阐述了MCU监控应用系统的接口特点,总结了该类系统各部分的可靠性设计原则。在分析汽车电磁环境及接口特点的基础上,研究抗电磁干扰(EMI)的设计方法。经大量实地与模拟测试,得出了车载通信终端设备在开关量采集、TVS管在抑制汽车瞬态干扰方面的应用、感性负载干扰脉冲抑制、信号线束的干扰屏蔽、电路板抗EMI设计、可靠性软件设计等方面可采取的行之有效的方法措施。 本文为车载通信设备的抗干扰设计提供了借鉴的思路。进而可以减小实际设计中的盲目性和局限性。更多还原

【Abstract】 This dissertation studys reliable interface technology of the embed MCU application system, based on the reliable design of GSM/GPS automobile-mounted orientating system terminal.. Especially it discusses the anti-jamming technology of automobile-mounted communication terminal. It includes works for: the EMI characteristic of the the embed MCU application system interface, the design rules of system reliability, automotive electromagnetic environment and interface characteristic, anti-interference design of automobile-mounted communication terminal.To design reliable automobile-mounted communication terminal.we analyse the interface characteristic of MCU monitor-control system、 the reliable design rules of the kind of system is summarized..study the design methodof anti-EMI on the basis of analyzing automotive electromagnetic environment and interface characteristic. By much spot and simulative testing, we educe effective measures to : on-off data capturing of automobile-mounted communication terminal、 application of TVS on suppressing automotive transients、 suppression of inductive-load interference pulse、 interference shielding of signal wiring harness、 EMI design of printed circuit board and reliable software design.The dissertation provides a reasonable method of reference on the anti-jamming design of automobile-mounted communication equipment. What’s more, blindness and limitation in application design may be lowered.更多还原
