| 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。

| Abstract: | 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. |
