An optical fiber buried laser light source earthquake alarm device

Abstract

The invention discloses an optical fiber buried laser light source earthquake alarm device, which includes an earthquake alarm device body. The earthquake alarm device body includes a laser, an optical fiber, a seismic wave cracking device and an intelligent alarm system. The seismic wave cracking device includes an Detachable light guide plate, the detachable light guide plate is provided with a reset device, the laser emits laser to generate a signal, the laser or signal propagates along the optical fiber, the detachable light guide plate separates when encountering an earthquake or feeling seismic waves, the laser transmission The interruption cannot transmit signals along the optical fiber to the signal collector of the intelligent alarm system. When the signal collector cannot receive the signal or the signal is interrupted, it is determined to be an earthquake and the intelligent alarm system alarms. When the signal collector can receive the signal, No earthquake occurred. The optical fiber buried laser light source earthquake alarm device of the present invention is simple and practical, has high sensitivity, can issue early warnings for earthquakes, has low manufacturing cost, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of earthquake alarm, in particular to an optical fiber buried laser light source earthquake alarm device. 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 However, due to industrialization With the development of urbanization, this natural prediction method is no longer applicable. Nowadays, earth...

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
