摘要
为克服传统接地网接地电阻测量仪需要建辅助地极、测量结果受限因素多、测量精度低的缺点,提出一种基于SPCE 061A单片机的新型便携式免地桩接地电阻测量仪,并给出了仪器设计的硬件结构及软件流程图。该测量仪采用双钳口法测量激励、检回信号,运用数字信号处理(DSP)技术,实现了实时测量分析、快速处理数据和历史数据管理等功能,并能有效地消除电磁干扰影响,提高了测量精度,具有操作简单、小巧轻便、成本低等优点。
The traditional grounding resistance meter has several defects,such as needing auxiliary earthed poles,measurement results being influenced by many factors,the measurement accuracy being low,and so on. A portable grounding resistance meter based on SPCE 061A is introduced and its hardware architecture and software flowchart are offered. The DSP（Digital Signal Processing ） -based instrument measures the power and check-back signals with two clamps to realize real-time measuring and analysis,fast data processing and historic data management. It eliminates the influence of electromagnetic interference effectively and improves the measurement precision,being small,cheap and easy to be operated.
