Abstract

According to the defect of the building ground resistance measuring device presently. A new system of building ground resistance detection which based on STM32 was proposed. This scheme was based on the principle of three-pole compensation method. Hardware and software of the master-slave machine which controlled by embedded system was applied to achieve accurate measurement of ground resistance. The detection system included synthesizer of alternating current, signal collecting and data processing platform. The detection system was consisted of a STM32 control which product alternating current with high precision frequency and waveform stability into the grounding grid. The signal of voltage and current in the grounding grid were translated into a precise grounding resistance value through band-pass filter, differential amplify, synchronous AD conversion, FFT processing. The detection system could improve the detection accuracy and efficiency, and realize the intelligent testing work.
