Angle sensor provided with temperature compensation optical fibers and used for measuring level angle of pole tower

The invention discloses an angle sensor provided with temperature compensation fibers and used for measuring a level angle of a pole tower. The angle sensor comprises a sensor packaging casing, a base plate, a platy swing arm, a swing hammer, a first jackscrew and a second jackscrew, wherein the base plate is fixedly connected to the top of the sensor packaging casing; one end of the platy swing arm is fixed on the base plate; the swing hammer is fixed at the other end of the platy swing arm; the first jackscrew is arranged on the left side of the sensor packaging casing and corresponds to one end of the swing hammer; the second jackscrew is arranged on the right side of the sensor packaging casing and corresponds to the other end of the swing hammer; strain detection optical fiber Bragg gratings are attached in the length direction of the platy swing arm; and environment temperature detection optical fiber Bragg gratings are in series connection with the strain detection optical fiber Bragg gratings. According to the angle sensor, high-precision level angle measurement of the pole tower can be realized and is not affected by an electric field or the environment temperature.
