Abstract: This paper proposes a signal digital filtering technology that filters the noise of safety monitor ⁃ ing instruments to obtain stable and reliable monitoring results, thereby maintaining safe and stable sig ⁃ nal output. This technology can reduce the impact of external magneto electric changes on signal output of instruments and extend the service life of instruments. It has achieved good results in the production of actual safety monitoring data, which has reference significance for the calibration of similar dam safe ⁃ ty monitoring instruments.
