Multipurpose ground stress electric field monitoring device

Abstract

The invention discloses a multipurpose ground stress electric field monitoring device, and belongs to the technical field of electric field monitoring. The device comprises at least one electric field sensor, an information filter module, a composite bridge amplifying module, a differential motion amplifying module and a display module. The electric field sensor is used for acquiring electric field information. The information filter module is used for filtering out earth background electric field information and environment static interference information in the electric field information. The composite bridge amplifying module is used for carrying out bridge type amplification on the filtered electric field information. The differential motion amplifying module is used for carrying out differential motion amplification on the electric field information obtained after bridge type amplification. The display module is used for displaying the electric field information obtained after differential motion amplification. The device is a disaster early warning electric field information monitoring instrument, and is used for preventing disasters and reducing damage, and is a ground stress electric field early warning information monitoring device which is used for achieving earthquake forecasting for human beings before earthquakes and is excellent in performance, safe and convenient to use.

Description

technical field [0001] The invention relates to the technical field of electric field detection, in particular to a multi-purpose ground stress electric field monitoring device, especially for the monitoring of early warning information of ground stress electric field before an earthquake, the monitoring of underground ground electric field in mines, the monitoring of harmful electric fields in human settlements and industrial environments, and various Non-contact monitoring of energized electric field and static electric field of facilities and equipment, non-contact detection of buried power supply line laying path, non-contact inspection of hidden line and cable core wire open circuit fault, long-distance electrification electric field of overhead high-voltage transmission lines and high-level electrical equipment test etc. Background technique [0002] Earthquake prediction has always been the goal pursued by human beings throughout history.

[0002] Earthquake prediction has always been the goal pursued by human beings throughout history. How to detect and grasp the underground early warning information before earthquakes occurs is a world-class topic for earthquake prevention and disaster reduction work in this era; some electric fields in human living and working environments are related to human health, but It is ignored by people because of its "invisibility"; the static electricity on the facilities and equipment of some special industries is easy to cause safety accidents inadvertently; some building physical design power supply lines are updated and reconstructed, and the route of line laying is identified in advance. An important prerequisite for construction efficiency and reduction of renovation costs; for troubleshooting of concealed lines and open circuits of cable core wires, it has always been difficult to determine the location of the fault from the outside, often resulting in a large waste of manpower and material resources
