Fiber laser earthquake monitoring early warning device

Abstract

The invention discloses a fiber laser earthquake monitoring early warning device comprising a metal tube, an optical fiber, a laser, a range finder, a data acquiring end, a data transmitting end, and an earthquake alarming device. The metal tube is vertically disposed under a ground surface, and the upper end of the metal tube is exposed out of the ground surface. The optical fiber is vertically disposed in the metal tube, and the laser is disposed on the upper part of the metal tube, and is connected with the optical fiber. The range finer is disposed on the metal tube on the upper part of the ground surface, and the data acquiring end and the data transmitting end are disposed on the ground surface, and are electrically connected with the range finder. The earthquake alarming device is disposed on the ground surface, and is electrically connected with the data transmitting end. When an earthquake occurs, the metal tube under the ground surface is distorted and deformed, and the optical fiber is compressed or even destroyed, and then the circuit of the range finder is used to detect the distortion deformation position, and is used to transmit a signal to the data acquiring end, and then the signal is transmitted by the data transmitting end, and in addition, the earthquake alarming device is used to give alarms. A control center is disposed on the ground surface, and the control center is used to transmit the received signal to a personal cell phone mobile terminal by a communication system in order to prompt population evacuation.

Description

technical field [0001] The invention relates to an early warning device, in particular to a fiber laser earthquake monitoring and early warning device. Background technique [0002] Earthquake, also known as ground motion and ground vibration, is a natural phenomenon in which vibration is caused by the rapid release of energy from the earth's crust, during which seismic waves are generated. Earth's plates are squeezed and collided with each other, causing dislocation and rupture at the edge of the plates and inside the plates, which is the main cause of earthquakes. The place where an earthquake begins is called the epicenter, and the ground directly above the source is called the epicenter. The place where the ground vibration of a destructive earthquake is the strongest is called the episeismic area, and the episeismic area is often the area where the epicenter is located. Earthquakes often cause serious casualties, and can cause fires, floods, toxic gas leakage, bacteri...

Problems solved by technology

[0003] In ancient times, there were seismographs that could predict the occurrence of earthquakes. With the development of science and technology in modern times, people use a variety of scientific and technological means to detect the movement of subsurface plates to achieve the purpose of monitoring earthquakes. The results have certain deviations. Once it happens, it will cause huge losses to people, and it cannot effectively remind the masses to evacuate and evacuate.
