Earthquake forecasting instrument and using method thereof

Abstract

The invention provides an earthquake forecasting instrument which comprises a base, a coil, an alternating current amplifier, a current-limiting gate and an alarm device, wherein the coil is vertically arranged above the base; the coil, the alternating current amplifier, the current-limiting gate and the alarm device are sequentially connected; an amplification factor of the alternating current amplifier can be adjusted; the alternating current amplifier is provided with discontinuous gears; and the current-limiting gate is structurally characterized in that the current-limiting gate is conducted when an input voltage is larger than a rated voltage and is cutoff when the input voltage is less than the rated voltage. The earthquake forecasting instrument can monitor earth magnetism abnormal fluctuation in the early stage of earthquakes, has simple structure and low cost, is free from environmental influence and is convenient for a person to carry and use.

Description

Technical field [0001] The invention relates to the field of electronic technology, in particular to an earthquake prediction instrument for monitoring geomagnetic changes and having an earthquake prediction function, and a method for using the same. Background technique [0002] In recent years, the movement of the earth's crust has been relatively active, and earthquakes have occurred from time to time, causing immeasurable disasters, such as the Wenchuan earthquake and the Yushu earthquake, which caused deep sorrow to the whole world. However, no practical and effective method has been proposed for the prediction of earthquake phenomena. [0003] At present, some earthquake observation centers use macroscopic animal phenomena to observe earthquakes, such as animal disturbances and abnormal migrations. Due to the large uncertainty of such phenomena, it is difficult to determine whether an earthquake is imminent even if there is an anomaly. [0004] It is more advanced and...

Problems solved by technology

However, earthquake prediction is not just a technical problem. Due to the high cost and complicated operation of the current geomagnetic monitoring equipment, it is only owned by specialized institutions and cannot be extended to individuals. Due to the large area involved when the geomagnetic anomaly occurs, It is impossible for officials to broadcast earthquake warning at will, otherwise the vast cities will be paralyzed. Therefore, the development of portable earthquake predictors that can be used flexibly by individuals is the key to solving this problem; on the other hand, although the current geomagnetic records The instrument can accurately record the geomagnetic fluctuation curve, but the work of converting abnormal fluctuations into alarm signals still needs to be developed. Divide, and then amplify the low frequency fluctuations, in this case, we start from image 3 It can be seen that what is obtained is a fluctuation with a small change slope. Within six hours, the change (enhancement or weakening) of the geomagnetic anomaly is only about 600nT, that is, the rate of change of the magnetic induction intensity is 2.78×10 -11 T / s, for such a small rate of change, is often affected by the surrounding environment, such as high-voltage power grids, trains, etc. Therefore, the filtering method is only suitable for long-term statistics, not suitable for real-time monitoring of geomagnetism. Personally, I don't have the energy to make such statistical observations
