A Fiber Laser Earthquake Warning Method for Distinguishing Magnitude

Abstract

The invention discloses a reusable fiber laser earthquake alarming method capable of distinguishing earthquake magnitudes. An earthquake alarm body and an alarming method are involved. The earthquake alarm body comprises a laser, an optical cable, an earthquake wave shattering device, a signal receiver and an intelligent alarming system. The earthquake wave shattering device comprises one or more separable light guide strips which are arranged side by side, the hardness, strength and thickness of the divided separable light guide strips are different, the separable light guide strips correspond to different earthquake magnitudes, the separable light guide strips can be separated according to earthquake intensity or force, lasers or signals are diffused along the optical cable, the separable light guide plates are separated when encountering with an earthquake or sensing earthquake waves, signals cannot be transmitted to the signal receiver along the optical cable when laser transmission is interrupted, and the intelligent alarming system gives an alarm when the signal receiver does not receive signals or the signals are interrupted. The alarming method is simple, practical and high in sensitivity, and can give an alarm for the earthquake in advance and judge the earthquake magnitudes.

Description

technical field [0001] The invention relates to the technical field of earthquake alarms, in particular to an optical fiber laser earthquake alarm method for distinguishing earthquake magnitudes. Background technique [0002] Earthquake is a devastating natural disaster that cannot be resisted by humans. Earthquakes can cause huge destructive power in an instant. Earthquakes have occurred since ancient times. Due to human force, all we can do is to discover in advance, warn in advance, and evacuate in time , so earthquake early warning devices have attracted great attention from humans. In ancient times, there were seismographs that could predict the occurrence of earthquakes. Before earthquakes, there were many strange geographical phenomena that could effectively predict earthquakes, such as abnormal behavior of animals and abnormal behavior of weather. However, due to industrialization With the development of urbanization, this natural prediction method is no longer appli...

Problems solved by technology

[0003] At present, earthquake detection and alarm devices are mostly used in national professional earthquake detection centers or scientific research institutions. Because these machines are sophisticated, bulky, and expensive, and the sensors of these earthquake detection devices have to be placed in specific areas and specific depths, they cannot be used in residents' daily life. It is widely used in daily life. When an earthquake disaster occurs, residents cannot receive the alarm prompt at the first time and avoid the disaster in time. People are often caught off guard and it is difficult to minimize casualties and property losses. The existing earthquake alarm system also exists Large area, inaccurate forecast, high cost, unfavorable for popularization and use
