Description

Technical Field

[0001] The invention belongs to the technical field of ground subsidence monitoring, and in particular relates to a ground subsidence monitoring device. Background Art

[0002] The commonly used methods for measuring ground subsidence mainly include leveling, which has relatively low cost and is more suitable for long-term monitoring. A stable point is selected as a reference point, and the fluid reservoir of the reference point is placed at a position with a known elevation. The fluid reservoirs of other measuring points are placed at the positions where the settlement needs to be measured.

[0003] In the patent number CN202411937373.1, when the measuring point rises or falls relative to the reference point, the liquid level at each point will change accordingly due to the free flow of liquid in the connecting pipe. A high-precision pressure sensor is required to measure the pressure difference and then detect the sedimentation depth. The high-precision pressure sensor needs to be powered. In outdoor coal mine exploration and goaf area detection, the working environment is harsh and the circuit layout is inconvenient.
