中文摘要：
点检是掌握设备运行状态的重要手段。点检仪由数据采集、人机交互、通信和存储等单元组成；采用ARM微处理器，设计了数据存储、信号采集等硬件电路；构建了嵌入式Linux操作系统，编写了设备驱动和仪器应用程序，以实现对振动、温度、设备条码信息、观察量、抄表量的采集和管理；仪器通过USB接口与上位机通信；点检仪小巧、便携、使用方便，和后端软件一起组成的点检管理系统可有效提高设备管理的自动化水平。
英文摘要：
Spot inspection is one of the important means to master machine device condition. The designed measurement instrument was composed of data acquisition, man-machine interface, communication, storage, etc. ARM based microprocessor was adopted. The instrument circuits such as data storage, signal acquisition were designed. Then the embedded Linux operating system was built up. The instrument device drivers and applications were programmed. The instrument can collect vibration signals, temperature signals, electronic registration numbers of devices, obervations on the plant and meter readings. The instrument communicated with master computer through USB interface. The designed instrument was portable and easy to use. The device management automation level can be largely improved by using the spot inspection system made up of the instrument and the software running on the server.
