远程故障诊断系统数据采集仪的软件设计与实现

Design and Implementation of the Software for the Data Acquisition Device in the Remote Fault Diagnosis System

介绍了远程故障诊断技术的现状及其优缺点,在此基础上提出了改进方案.基于该方案,采用AT91RM9200开发板和嵌入式开发环境uC linux实现了远程故障诊断系统数据采集仪的软件,使系统既能通过指挥所内局域网又能通过串行线进行远程故障诊断工作,解决了局域网发生故障时,无法进行远程故障诊断的问题.

In this paper, the current situation and the advantages/shortcomings of the remote fault diagnosis technology is introduced. On the basis, a modified scheme is proposed. In the system, a microprocessor AT91 RM9200 and the embedded development environment uclinux are adopted to fulfil the programming of the data acquisition device in the remote fault diagnosis system. Thus, the remote fault diagnosis can be realized through both LAN and serial port in the commanding post.
