IDE硬盘在准在线故障诊断系统中的应用研究

摘要

准在线故障诊断系统在现场长时间对设备进行状态监测和故障诊断时,常常需要较大的存储容量.为了满足系统要求,可在准在线故障诊断系统中扩展IDE硬盘.介绍基于OMAP5912的准在线故障诊断系统结构,提出系统的IDE接口扩展方式,并分析了Linux系统下的硬盘驱动流程,实现了IDE硬盘在该系统上的扩展应用.%Mass storage is always necessary for quasi-line fault diagnosis system when the system is used for on-line fault diagnosis, condition monitoring and so on. In order to meet the requirement, IDE disk can be applied in the quasi-line fault diagnosis system. The system structure of the quasi-line fault diagnosis system based on OMAP5912 was introduced. A method of designing IDE disk interface in the system was provided. The driver for the hard disk in Linux operating system was analyzed. The application of IDE disk in the quasi-line fault diagnosis system was realized.
