Sensor packaging mechanism, monitoring device and monitoring system

The invention discloses a sensor packaging mechanism which comprises an optical fiber sensor and a packaging shell, a packaging cavity capable of containing the optical fiber sensor is formed in the packaging shell, a main body part of the optical fiber sensor is located in the packaging cavity, and an optical fiber of the optical fiber sensor extends out of the packaging shell; the packaging cavity is also filled with a packaging material, and the packaging material wraps the optical fiber sensor and fills the space between the optical fiber sensor and the inner wall of the packaging shell; the packaging material is sealing glass, the packaging shell is made of a metal material, and the sealing glass and the packaging shell are sealed into an integrated structure. According to the sensor sealing mechanism, the sealing glass is selected as a packaging material, the packaging shell is made of a metal material, and the sealing glass and the packaging shell are sealed into an integrated structure, so that the ad
