The present invention discloses a telemetry and telecontrol horizontal and vertical displacement meter which comprises a test tube arranged in a borehole at a predetermined position of a dam body. A settling magnetic ring is arranged out of the test tube, and a measuring probe is arranged in the test tube. An angle sensor and a magnetic field strength sensor are arranged in the measuring probe. The angle sensor and the magnetic field strength sensor in the measuring probe are connected with a double core cable, and the other ends of the double core cable are respectively connected with a horizontal displacement display instrument and an electromagnetic intensity display instrument. A horizontal displacement and vertical displacement integrated test system according to the invention integrates horizontal displacement and vertical displacement testing equipments into a system. The test tube is only embedded in one dam borehole. The probe moving in the test tube simultaneously measures the dam horizontal displacement and the vertical displacement. The electromagnetic intensity display instrument is added, and the test accuracy is improved. The telemetry and telecontrol horizontal and vertical displacement meter provides a more appropriate technical means for the railway roadbed deformation monitoring.
Description
technical field [0001] The invention relates to a displacement meter, in particular to a horizontal and vertical displacement meter with remote measurement and remote control, and belongs to the field of monitoring equipment for water conservancy and hydropower projects. Background technique [0002] For dams in water conservancy and hydropower projects, especially earth-rock dams, the deformation of the dam needs to be monitored during the construction process, and long-term monitoring is required after the dam is completed. The deformation of the dam includes vertical displacement and horizontal displacement. In the prior art, this kind of monitoring adopts a horizontal and vertical displacement meter, and its structure includes two parts. The horizontal displacement monitoring part: fix a measuring point on the measuring point in the dam body Steel wire, the other end of the steel wire is wound on the small wheel of a wheel shaft system; a suspension steel wire rope is wo...
