Reliable Interface Design And Application In Vehicle Orientating System Of Embed MCU

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.
