摘要
通过对杂散电流腐蚀危害的分析以及国内外相关杂散电流检测仪器设备的性能比较,重点介绍了交直流杂散电流的设计思路、性能指标、实现方法等问题。在该杂散电流仪的设计中,采用平板电脑作为上位机,STM32F103C8T6单片机作为下位机,主要用于采集和处理石油管道中的杂散电流信号,以及参比电压信号。设计中还采用了Lab VIEW可视化编程,方便了界面的修改和仪器的维护。通过精度测试,测试结果满足了设计要求。
Based on an analysis of risks of the stray current corrosion and a comparison of the performances of existing stray current detection devices, this article discusses the design, performance indicators and implementation of the AC/DC stray current meter. A tablet is adopted as the upper computer and STM32F103C8T6 as the lower computer for acquisition and processing of stray current signals from the oil pipeline and the reference voltage signals. LabVIEW is adopted in the design of visual programming for the modification of the interface, which facilitates maintenance. Precision tests show that the design meets the requirements.
