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...

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0022] exist Figure 1-Figure 2 In the shown embodiment, the earthquake prediction instrument includes a base 3, a coil 1, an AC amplifier 202, a current limiting gate 203, and an alarm device 2; Above the base 3, specifically, it can be installed on a coil frame made of non-conductive material above the base 3, figure 1 omitted.

[0023] The coil 1, the AC amplifier 202, the current limiting gate 203, and the alarm device 2 are sequentially connected; During the blocking process, the AC amplifier 202 is in the disconnected state; the current-limiting gate 203 has the structural characteristics that it is turned on when the input voltage is greater than the rated voltage, and is cut off when the input voltage is lower than the rated voltage. For example, it can be formed by an avalanche diode. When the value is below the threshold value, the output is cut off....
