Problems solved by technology

[0004] Optical fiber sensing technology is in its infancy in my country, and its mainstreams are BOTDR and BOTDA based on Brillouin optical time domain reflectometry, ROTDR based on Raman distributed temperature sensing technology, and quasi-distributed fiber Bragg grating sensing technology. FBG, etc., these technologies have superior performance, but the price is very expensive and cannot reach the level of popularization and application

Abstract

The invention belongs to the technical field of sensors and specifically relates to a precaution device for geological disaster events. The precaution device includes a control host which includes a signal generating module, a signal detection module and a control module. Event sensors are connected between the signal generating module and the signal detection model through optical cables. The signal detection module is connected with the control module. The other end of the control module is also connected with an alarm module and a power-supply module. The precaution device improves the precaution response speed and stability of geological disaster events and improves the coverage range of a geological-disaster monitoring system and reduces the monitoring cost.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to an early warning device for geological disaster events. Background technique [0002] According to incomplete statistics, the economic losses caused by various natural and engineering disasters in my country amount to hundreds of billions of dollars every year. Therefore, preventing and controlling various natural and engineering disasters, reducing disaster losses, and solving related key technologies are unavoidable missions for our government and scientific and technological workers. In order to reduce the losses caused by various disasters, countries around the world, such as Japan, the United States, the United Kingdom, and Germany, have invested a lot of manpower and material resources in the research and development of various disaster monitoring and early warning technologies, and developed such technologies as precise geodetic surveying and close-range photography. , GP...
