基于ARM的嵌入式故障诊断系统方案的研究

Research of embedded fault diagnosis expert system scheme based on ARM

本文讨论基于ARM的嵌入式故障诊断系统的平台开发,重点研究系统的体系结构和软硬件的实现。该系统采用ARM芯片作为处理器,Flash芯片作为系统的存储介质,通用的串行总线作为计算机数据传输接口,以太网作为向上一层系统传送信息的媒介,CAN总线作为外部数据信号的接收端口。从嵌入式平台的特点和故障诊断系统的功能出发,提出了基于ARM内核的CPU和WinCE的嵌入式故障诊断系统的整体解决方案。

This paper discuss about embedded system of an integrative fault diagnosis expert system base on ARM chip. Especially, it concerns about the system＇s architecture and the development of the hardware and software platform of the embedded system. This system provided the ARM as the main processor. Flash chip is used as the storage facility. It also provided with USB interface to PC. Ethernet network is embedded as the medium which received and transmitted the data from the upper layer. CAN bus is used to receive outer signals. In the light of the feature of embedded system and the function of fault diagnosis expert system, the paper draws out the whole solution of embedded fault diagnosis expert system scheme base ARM and WinCE technology.
