本文分析嵌入式设备的特点，并在此基础上提出充分利用嵌入式设备提供的接口资源，
实现故障检测和诊断的方法，将设备故障定位到电路板级，为板级电路的故障检测和诊断奠定基础。此种方法在复杂工程环境下，无需拆卸嵌入式设备即可判断整机性能，达到故障检测和诊断的基本要求。在这一方法基础上，本文以某车载GPS 导航系统为被测对象，详细介绍了故障检测和诊断系统设计。
关键词：串行通讯；嵌入式设备；故障检测与诊断
Abstract: According to the characteristics of the embedded equipment, a fault detection and
diagnostic technique based on serial communication is put forward in the paper. This method
achieves the board-level fault detection, provides foundation for the component-level fault
detection and diagnosis, and meets the basic needs of fault detection and diagnosis without
disassemble the equipment under complex environments. Based on this method, the paper
introduces a fault detection and diagnosis system designed for the GPS navigation system.
Keyword: serial communication; embedded equipment; fault detection and diagnosis.
