Acceleration sensors are adopted to acquire acceleration data of southeast, northwest and vertical directions of an earthquake, whether an earthquake event exists or not is judged according to acceleration, a GPS (Global Positioning System) module is adopted to determine the position of an epicenter, and the earthquake event and the position of the epicenter are transmitted to an earthquake monitoring center through an GSM (Global System for Mobile Communication) module.
Description
Technical field
The present invention relates to disaster prior-warning device, be specially a kind of earthquake monitoring system.
Background technology
Earthquake, because of its sudden and wasting feature, becomes one of major natural disasters of harm humans life.Research in seismic monitoring emerges in an endless stream, and the accuracy requirement of people to seismic monitoring is also more and more higher.At present, usual earthquake monitoring system is by seismic network determination earthquake magnitude and the seismic origin, monitoring distance is limited, have only and increase the degree of accuracy that seismic network density could improve prediction, and the density increasing seismic network often mixes the consumption of broken huge human and material resources and financial resources.
