Abstract
The invention provides an earthquake monitoring system. An accelerometer is adopted to collect acceleration data in the southeast direction, the northwest direction and the vertical direction of an earthquake. People can determine whether the earthquake occurs according to acceleration. A GPS module is adopted to determine the position of an epicenter, and a GSM module is employed to send the earthquake and the epicenter of the earthquake to an earthquake monitoring center.
Description
Technical field
The present invention relates to disaster prior-warning device, be specially 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.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of just can the earthquake monitoring system of accurate measurements earthquake on a large scale without the need to relying on other seismic network.
The present invention is solved the problem by following technological means:
Earthquake monitoring system, forms primarily of central processing unit, acceleration detection module, Signal-regulated kinase, A/D modular converter, GPS module, gsm module and memory module;
The described output terminal of acceleration detection module is connected with the input end of Signal-regulated kinase, the output terminal of described Signal-regulated kinase is connected with the input end of A/D modular converter, the output terminal of described A/D modular converter is connected with central processing unit, the output terminal of described GPS module is connected with central processing unit, and the input end of described gsm module is connected with central processing unit.
Further, the acceleration transducer of described acceleration detection module is 3-axis acceleration sensor.
Advantage of the present invention and beneficial effect are:
The invention provides a kind of earthquake monitoring system, acceleration transducer is adopted to gather the acceleration information in the earthquake southeast, northwest and vertical three directions, seismic events has been judged whether according to acceleration, adopt GPS module to determine the position in earthquake centre, and by gsm module, seismic events, position, earthquake epicenter are sent to seismic monitoring center.

Embodiment
Fig. 1 gives hardware block diagram of the present invention.Earthquake monitoring system, forms primarily of central processing unit, acceleration detection module, Signal-regulated kinase, A/D modular converter, GPS module, gsm module and memory module.
The output terminal of acceleration detection module is connected with the input end of Signal-regulated kinase, the output terminal of Signal-regulated kinase is connected with the input end of A/D modular converter, the output terminal of A/D modular converter is connected with central processing unit, the output terminal of GPS module is connected with central processing unit, the input end of gsm module is connected with central processing unit, and input end and the central processing unit of memory module are bi-directionally connected.Wherein, the acceleration transducer of acceleration detection module is 3-axis acceleration sensor.
Using 3-axis acceleration sensor as seismic acceleration signal sensing unit, acceleration sensor module output signal is connected central processing unit I/O port by after Signal-regulated kinase and A/D modular converter.The acceleration information in the southeast, acceleration sensor module Real-time Collection ground, northwest and vertical three directions, central processing unit use short long time mean ratio (STA/LTA) method determine whether seismic events, and the time utilizing GPS module to receive then carries out record to P-wave; Then the first motion direction of P-wave three components is utilized to determine orientation, earthquake centre, and by the first motion displacement determination epicenter azimuth of P-wave three components, the last earthquake source distance calculated in combination with experimental formula, just preresearch estimates can go out the position of earthquake source, namely complete the location tasks of seismic events; Eventually through the earthquake magnitude of mathematical statistics relational expression determination earthquake.
Signal-regulated kinase is used for the information that detected by 3-axis acceleration sensor and nurses one's health, and makes it input to meet the input requirements of A/D modular converter, and the information after conditioning converts to digital from analog by A/D modular converter, is convenient to central central processing unit process.
Gsm module is used for seismic events, and seismic monitoring center is sent to note form in epicentral location.
Memory module be used for by the longitude and latitude P ripple of earthquake monitoring point then and seismic event records of acceleration in memory module.
The present invention 24 hours continuously locality areal acceleration data, the acceleration information collected can by short long time average specific method (STA/LTA) judge whether this ratio has exceeded the threshold value pre-set due to earthquake, if so, then automatically to detect and the data utilizing GPS module to receive carry out record to the first break time of P-wave; Then P-wave is utilized to carry out corresponding integral operation to the acceleration information of first 3 seconds and utilize file system to be recorded in SD card in the form of a file by these acceleration informations; Then the first motion direction of P-wave and the position angle of first motion displacement determination earthquake is utilized; Finally utilize the earthquake magnitude of two mathematics statistical relationship determination earthquakes and the hypocentral distance of earthquake, and the epicenter azimuth calculated, earthquake magnitude and hypocentral distance are stored in memory module.
