Laser depth measuring instrument

Abstract

The invention discloses a laser depth measuring instrument, which comprises a console and a laser detector connected with the console. The laser detector comprises a laser transmitter and a laser receiver connected with the laser transmitter. The laser receiver is connected with the laser transmitter through an optical fiber. The laser transmitter is connected with the console, and the console isconnected with the laser receiver through the optical fiber. The laser receiver comprises an anti-seismic room, a laser receiver arranged in the anti-seismic room, and a photoelectric signal processorand a sonar detector which are connected with the laser receiver. The laser receiver is connected with a photoelectric signal processor, and the photoelectric signal processor and the sonar detectorare connected with the console through optical fibers, and the laser receiver is connected with the laser transmitter through the optical fiber. The laser depth measuring instrument is simple and practical, the sensitivity is high, an alarm can be given out in advance for the earthquake, and the earthquake level can be judged.

Description

technical field [0001] The invention relates to the technical field of earthquake detection, in particular to a laser depth measuring instrument. 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 However, due to industrialization With the development of urbanization, this natural prediction method is no longer applicable.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, earthquake early warning devices ...

[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, earthquake early warning devices are installed in many places, which is the crystallization of modern technology, but the effect is not very good, and it can no longer meet people's needs very well.

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
