Abstract
The weak signal acquisition such as SF6 is affected by power frequency interference and sensor polarization voltage. If the integrated instrument amplifier is directly used as small signal amplifier, there are some problems, such as large data deviation. In this paper, a redundant monitoring system combining temperature compensation method and multi-stage gain is established, and the soft threshold denoising method is used to filter the interference signal, and the SF6 on-line data monitoring is realized by STM32F4 single chip microcomputer.
