Sensing probe AETA suitable for imminent earthquake monitoring of great earthquake

Abstract

The invention discloses a sensing probe AETA suitable for imminent earthquake monitoring of a great earthquake. The sensing probe AETA is characterized in that the sensing probe is composed of a nonmagnetic stainless steel housing, a sound transmission rod, a ground acoustic sensor set, an electromagnetic radiation sensor, a temperature sensor set, a seismic wave speed sensor set, a signal acquisition circuit, a shielding box of the signal acquisition circuit, a fixing member set, a flange and a lid, wherein the signal acquisition circuit is placed in the shielding box. The ground acoustic sensor set, the temperature sensor set and the seismic wave speed sensor set are fixed on the sound transmission rod respectively through a fixing member 1 and a fixing member 2. The electromagnetic radiation sensor is fixed through a pair of fixing members 3 between the sound transmission rod and the flange. One end of the housing is connected with the sound transmission rod through threaded connection, and the other end is connected with the flange through threaded connection. The lid is provided with two waterproof locking heads which are connected with the flange through a shielding cable and an optical cable in a screw connection manner. High-heat-conductivity pouring sealant is filled into the sensing probe. The sensing probe AETA can realize acquisition of a plurality of microscopic precursor signals and furthermore can be placed on a crustal bedrock for a long time for performing real-time seismic signal acquisition.

Description

technical field [0001] The patent of the present invention relates to the field of large earthquake monitoring equipment and circuit system design, in particular to a sensor probe AETA suitable for large earthquake imminent monitoring. Background technique [0002] After continuous movement and changes, the earth has gradually accumulated huge energy, causing sudden rupture of rocks in some fragile areas of the earth's crust, or triggering the dislocation of original faults. This is an earthquake. my country is one of the countries with the most severe earthquake disasters in the world's continents. On the land that accounts for about 1 / 14 of the world's land area, the number of earthquakes every year accounts for more than 1 / 3 of the world's land earthquakes. Strengthening research on countermeasures against earthquake disasters, improving the technical level of earthquake monitoring and prediction, and mitigating earthquake disasters are directly related and of great signi...

Problems solved by technology

However, the prediction of earthquake imminence is still a difficult problem in the world. The difficulty lies in the fact that the phenomenon of imminent earthquake is not consistent in different places, and it is difficult to repeat it in the same place.
