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, geological disasters such as earthquakes have occurred frequently in our country and around the world, which have brought serious harm to the lives and properties of the people in our country and the world. The Wenchuan Earthquake on May 12, 2008 killed nearly 100,000 people and caused direct economic losses of more than 800 billion yuan. On April 14, 2010, the Yushu earthquake killed more than 2,000 people. Hundreds of thousands of dead in Haiti earthquake, prosperous city in ruins. How to predict earthquake disasters and research activities on new technologies for reducing disaster losses has become an urgent problem to be solved at present. [0003] Most of the current earthquake alarms are large-scale professional equipment, suitable for special earthquake detection institutions, such as the Seismological Bureau or Earth...
