Embodiment Construction

[0012] Referring to the accompanying drawings, the present invention is to suspend a hollow magnet bar 1 in the air with a thin wire, and a laser emitter is arranged inside the magnet bar 1, and the light spot of the laser is played at a distance (outside 1 meter or several meters) In addition, on the CCD photoelectric sensor within the distance that the light spot of the laser can hit), the sensor senses the movement of the light spot, and connects with the computer to record the data on the computer. Under normal circumstances, the magnet will not rotate and the laser point will not move. The geomagnetic field will change drastically a few minutes or hours before the earthquake, causing the magnet rod to rotate slightly, which will cause the position of the laser point to shift. The offset is recorded by the CCD sensor In the computer, if it exceeds a certain range, the computer will alarm, and this range can be adjusted through computer software. In order to avoid the influ...

Abstract

The invention discloses an earthquake alarm, which is mainly characterized in that a hollow magnetic rod is hung in the air by a thin wire; the interior of the magnetic rod is provided with a laser transmitter; when the spot of laser hits on a CCD photoelectric sensor, the sensor senses the movement of the spot and is connected with a computer to record data on the computer; in normal condition, the magnet does not rotate, and the laser spot also does not move; the geomagnetic field changes severely a few minutes or hours before the earthquake to cause the magnetic rod to rotate slightly, thereby causing the position of the laser spot to offset, the offset is recorded in the computer by the CCD photoelectric sensor, if the offset is larger than a certain range, the computer alarms, and the range can be regulated by computer software. As the technical scheme in the invention is adopted, compared with the prior art, the earthquake alarm has the advantages of sensitive instrument, high precision, pure mechanical type, reliable work, and good ability of not being interfered by cell phone signals or thunder and lightening.

Description

Technical field [0001] The invention belongs to the technical field of earthquake early warning, and in particular relates to an earthquake alarm. Background technique [0002] Earthquake is a natural disaster that can cause huge disasters in an instant, and has brought immeasurable losses to the lives and property of people all over the world. The current technology is still unable to predict earthquakes before earthquakes. The magnitude 8 earthquake in Sichuan in 2008 brought huge losses to the people of our country. If the earthquake prediction can be done, it will greatly reduce or reduce the loss of people's lives and property. Contents of the invention [0003] The object of the present invention is to provide an earthquake alarm with high sensitivity and the function of alarming several minutes or hours before the earthquake, which can effectively predict earthquakes and greatly reduce the loss of people's lives and property. It is different from common instruments...
