Abstract:

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.

Key words: stray current detection;data processing system;data collection
