System and method for monitoring and early warning of volcanoes based on inclinometer and GPS

Abstract

The invention discloses a system and a method for the monitoring and early warning of volcanoes based on an inclinometer and the GPS. The system includes a tilt measurement subsystem, a GPS monitoring subsystem and a ground control early warning subsystem. The tilt measurement subsystem is configured to obtain the ground tilt degree according to deformation of the tilt measurement subsystem caused by the deformation of a ground structure due to the magmatic pressure or mass redistribution so as to determine the small deformation of the volcano ground movement and to make early warnings; the GPS monitoring subsystem is used for obtaining the original observation data to determine ground displacement amount caused by the volcano to administer corresponding volcano movement state monitoring; and the ground control early warning subsystem is used for receiving tilt measurement data and the GPS data of the tilt measurement subsystem and GPS monitoring subsystem, for processing the data and for analyzing and obtaining the early warning data and for making an early warning signal according to the set early warning value so as to realize the detection of volcano state. The system and the method of the invention make the monitoring of volcanoes more accurate and ensure the reliability of data.

Description

technical field [0001] The invention belongs to the technical field of disaster early warning, and relates to a geological disaster early warning system and method, in particular to a volcano monitoring and early warning system and method based on an inclinometer and GPS. Background technique [0002] The four modern active volcanic belts are mainly the Pacific Rim volcanic belt, the Atlantic volcanic belt, the Mediterranean volcanic belt and the East African volcanic belt. A large number of sensors have been installed to monitor these volcanic belts, and many seismic stations have been set up, such as St. Helens There are 13 around the volcano, 47 around the Kilauea volcano in Hawaii, and 6 around the Merapi volcano in Indonesia. , the process of volcanic activity often causes many small earthquakes, and large eruptions can cause strong earthquakes. Earthquakes also often lead to volcanic activity. At present, there are many solutions for volcano monitoring. Xiang Shengji...

AI Technical Summary

Problems solved by technology

At present, there are many solutions for volcano monitoring. Xiang Shengjian and others use earthquake monitoring equipment, landslide monitoring equipment, debris flow monitoring equipment, etc. to connect the client and alarm to remotely manage monitoring data; According to the earthquake cycle and the existing monitoring data of earthquakes and volcanoes, Zhang Keyuan artificially detonates the existing dormant volcanoes on the earth on a small scale when the pressure in the crust increases. The high-pressure material inside the earth is erupted in batches to reduce the pressure inside the earth; however, the monitoring system of the above-mentioned people requires a large amount of equipment, the accuracy of the data is not high, and the support of artificial manpower is large, and the small volcano in the early stage is not considered. Changes in the movement state of the ground surface, based on this, in view of the current situation of the existing volcano monitoring and early warning system, it is necessary to provide a low-cost, convenient and high-precision volcano monitoring and early warning system and method
