Embodiment Construction

[0015] Such as figure 1 As shown, the present invention discloses an earthquake alarm including a magnetic field sensing device, the magnetic field sensing device includes a magnetoresistance effect sensing unit 1, a comparison unit 2, an earthquake alarm output unit 3, and the magnetoresistance effect sensing unit 1 The output terminal is connected with the input terminal of the comparison unit 2, and the output terminal of the comparison unit 2 is connected with the input terminal of the earthquake alarm output unit 3; the magnetoresistance effect sensing unit 1 detects and transmits the geomagnetic parameters To the comparison unit 2, the comparison unit 2 is used to monitor changes in geomagnetic parameters. When the geomagnetism changes, the earthquake warning output unit 3 sends out prompt information.

[0016] According to research on domestic and foreign earthquake records and the latest scientific research results, the geomagnetic field is obviously abnormal a few hours b...

Abstract

The invention provides an earthquake alarm, which comprises a magnetic field induction device, wherein the magnetic field induction device comprises a magnetoresistive effect sensing unit, a comparing unit and an earthquake alarm output unit, wherein the output end of the magnetoresistive effect sensing unit is connected with the input end of the comparing unit; the output end of the comparing unit is connected with the input end of the earthquake alarm output unit; the magnetoresistive effect sensing unit is used for detecting a geomagnetic parameter and transmitting the geomagnetic parameter to the comparing unit; the comparing unit is used for monitoring the change of the geomagnetic parameter; and when the earth magnetism changes, the earthquake alarm output unit is used for transmitting prompting information. The invention has the advantages that: the geomagnetic parameter is detected by using the magnetoresistive effect sensing unit, the change of the geomagnetic parameter is monitored by using the comparing unit, promoting information is transmitted by using the earthquake alarm output unit when the external magnetic field change suddenly, and an earthquake is forecasted through the sudden change of the magnetic field, so that the forecasting of the earthquake is more timely and accurate. Moreover, a digitizing technology is adopted for the earthquake alarm provided by the invention, so that an early warning effect is achieved accurately.

Description

Technical field [0001] The invention relates to an alarm device, in particular to an earthquake alarm. Background technique [0002] In recent years, earthquakes and other geological disasters have occurred frequently in my country and around the world, causing serious harm to the lives and property of the people of my country and the world. The Wenchuan earthquake on May 12, 2008 killed nearly 100,000 people and caused a direct economic loss of more than 800 billion yuan. More than 2,000 people were killed in the Yushu earthquake on April 14, 2010. The death toll in the Haiti earthquake reached hundreds of thousands, and the prosperous city was in ruins. How to predict earthquake disasters and research activities on new technologies to reduce disaster losses have become an urgent problem. [0003] The current earthquake alarms are mostly large-scale professional equipment, which are suitable for special earthquake detection institutions, such as the Earthquake Administration or...
