摘要

本研究提出了一种信号数字滤波处理技术，将安全监测仪器噪声进行滤波处理，获得稳定可靠的监测结果，保持安全稳定的信号输出状态。该技术减弱了外部磁电变化对仪器信号输出的影响，延长了仪器使用寿命，在实际安全监测数据生产中取得良好效果，对同类型大坝安全监测仪器的校准具有借鉴意义。

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.
