中文摘要：
在机械设备故障诊断中,为了能及时、快速地发现机械故障并作出相应处理构建了一种基于XPE（Windows XP Embedded, XPE）嵌入式操作系统,它是集数据采集、信号分析与数据传输于一体的便携式数采分析仪.该仪器既可以在工业现场对设备工况数据进行实时采集与分析,又可以将所采集的数据通过串口、USB口、网口等传输到上位机或者远程诊断中心进行更进一步的分析处理.通过在天津某发电厂的使用,实践证明,基于XPE操作系统的便携式数采分析仪运行稳定,在现场即可对机械设备的工况进行判断,加强了对机械故障的实时反应能力,具有一定的应用推广前景.
英文摘要：
In order to find the machine fault and take adaptive measures to deal with it accurately and in time for machine equipment fault diagnosis, a portable data- acquisition and signal -analysis instrument （PDASAI） based on XPE （Windows XP Embedded, XPE ） OS was introduced. PDASAI integrate data - acquisition, signal - analysis and data - transmission can realize real - time data - acquisition and signal analysis in the industrial field, and can transmit the data to super - computer or remote fault diagnosis center by serial port, USB port or ethernet port for deep analysis by experts. It is proved in a certain power plant in Tianjin that the PDASAI based -on XPE can effectively monitor the equipment condition in time in the field, which can enhance the reaction ability to the machine fault and has a good spreading value.
