便携式钻杆质量检测仪信号处理系统的设计

Design of signal processing system of portable quality detector for oil drill pipes

便携式钻杆质量检测仪可在油气开采现场对钻杆进行无损检测,野外作业的特点对信号处理系统提出了体积小、功耗低、检测灵敏度高以及与显示终端间数据传输灵活的要求。文章设计了一套完整的可进行信号采集、处理、显示的嵌入式软硬件系统和手持终端软件系统,嵌入式处理系统与手持式显示终端之间采用无线方式进行数据通信。整套系统性能符合相应的国家标准,能够满足野外开采现场对钻杆进行检测的需要。

Portable drill pipe quality detector can conduct nondestructive test on drill pipe at oil and gas extracting sites. The signal processing system fulfills the requirements of field operation with compact size, low power consumption and high detection sensitivity with flexible data transmission between display terminal and DSP. The embedded software and hardware system and the software for portable display terminal system are designed, working as a complete set for data acquisition, processing and display. The system which owns relatively high sampling sensitivity and sampling precision with wire less transmission for terminal data is suitable for the drill pipe testing in field extracting operations, and it meets the requirements of related national standards.
