The invention provides an earth electricity observation environment electric leakage monitoring and data abnormity verifying instrument. The verification instrument comprises a plurality of measurement channels which are respectively in signal connection with a geoelectricity observation system, a geoelectric field observation system and each measurement pole for earth electricity and geoelectric field observation field electric leakage inspection; the voltage acquisition module is respectively connected with the plurality of measurement channels and is used for carrying out voltage acquisition on measurement pole signals connected with the measurement channels; the signal processing module is connected with the voltage acquisition module and is used for processing the signal after voltage acquisition; and the industrial control board is connected with the signal processing module, is provided with a display screen, and is used for carrying out statistical analysis and fault judgment on the acquired signals subjected to signal processing. The earth electricity observation environment electric leakage monitoring and data abnormity verification instrument provided by the invention can be used for carrying out statistical analysis on measured data and judging whether a fault occurs or not or judging the type of the fault according to a data waveform characteristic analysis result.

Description

technical field [0001] The invention relates to the technical field of seismic observation, in particular to a geoelectric observation environment leakage monitoring and data anomaly verification instrument. Background technique [0002] Among the seismic observation instruments, the ZD8BI, ZD8M geoelectric instruments and ZD9A-II, ZD9A-2B, GFE-II geoelectric field instruments of the electromagnetic discipline, these instruments measure the underground resistivity and natural electric field through the earth, and the observation process is easy. It is easy to be disturbed by observation instruments, external line failures and leakage of observation sites, resulting in abnormal geoelectric data and missing measurements. These instruments cannot identify data anomalies caused by environmental leakage or observation system failure. [0003] At present, there are some digital multimeters and voltage measurement recorders in China, which can only simply measure the DC voltage be...

Problems solved by technology

[0002] Among the seismic observation instruments, the ZD8BI, ZD8M geoelectric instruments and ZD9A-II, ZD9A-2B, GFE-II geoelectric field instruments of the electromagnetic discipline, these instruments measure the underground resistivity and natural electric field through the earth, and the observation process is easy. It is easy to be disturbed by observation instruments, external line failures and leakage of observation sites, resulting in abnormal geoelectric data and lack of measurement, etc.

These instruments cannot identify data anomalies caused by environmental leakage or observation system failure

[0003] At present, there are some digital multimeters and voltage measurement recorders in China, which can only simply measure the DC voltage between electrodes, but cannot see the observation data curve, and it is difficult to analyze the cause of interference data
