Embodiment Construction
[0030] Such as figure 1 , figure 2 As shown, the optical fiber sensing geological disaster monitoring system of the present invention includes a laser light source 1 emitting optical signals, a photoelectric converter 2, an optical fiber coupler 3, an optical fiber line 4, a main control module 5, and a first wireless module 6; wherein, the main The control module 5 can be an MCU or a CPU, and the external monitoring terminal 7 can be a mobile device or a main control computer in a monitoring room. The optical fiber line 4 is a single-mode optical fiber line or a single-mode polarization-maintaining optical fiber line, and the optical fiber line 4 is buried horizontally In the geological layer and the distance between the optical fiber line 4 and the ground surface is greater than 2m, the optical fiber line 4 is soft and can be deformed according to terrain changes, so that the optical fiber line 4 can sense geological changes more accurately.
[0031] The optical fiber line...
