一种分布式光纤光栅测斜装置及测斜方法
摘要：
本发明公开了一种分布式光纤光栅测斜装置及测斜方法。所述分布式光纤光栅测斜装置包括内连接管，固定在内连接管内的光纤光栅倾角传感器，以及与光纤光栅倾角传感器相连的光缆；所述光纤光栅倾斜传感器包括有具有内腔的基座，第一光纤光栅和第二光纤光栅；所述基座顶部固定有悬臂摆，下端为自由端的悬臂摆上固定有第一光纤光栅；所述基座下部固定有第二光纤光栅，该第二光纤光栅悬空设置，且第二光纤光栅的两端固定在所述基座上；所述第一光纤光栅和第二光纤光栅通过光缆串接相连。本发明能抗电磁干扰、实现精确地远程实时监测。
摘要（英）：

The invention discloses a distributed fiber Bragg grating inclinometer device and a distributed fiber Bragg grating inclination metering method. The distributed fiber Bragg grating inclinometer device comprises an inner connecting pipe, a fiber Bragg grating tilt sensor fixed in the inner connecting pipe, and an optical cable connected with the fiber Bragg grating tilt sensor, wherein the fiber Bragg grating tilt sensor comprises a base with an inner cavity, a first fiber Bragg grating and a second fiber Bragg grating; a cantilever pendulum is fixed on the top of the base, and the first fiber Bragg grating is fixed on the cantilever pendulum of which the lower end is a free end; the second fiber Bragg grating is fixed on the lower part of the base and is suspended, and two ends of the second fiber Bragg grating are fixed on the base; and the fiber Bragg grating and the second fiber Bragg grating are connected in series by virtue of the optical cable. According to the device and method disclosed by the invention, electromagnetic interference can be resisted, and accurate real-time remote monitoring can be realized.
