Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As shown in the figure, the inclination sensor for landslide measurement in this embodiment includes a cylindrical shell 1, the inner cavity 2 of the cylindrical shell is cylindrical, and a liquid 3 is housed in the inner cavity of the cylindrical shell. Connected with a sensor seat 4, the sensor seat is provided with a CCD camera 5 for collecting liquid level images of the liquid in the inner cavity of the cylindrical shell, and the centerline of the CCD camera coincides with the centerline of the inner cavity of the cylindrical shell.

[0021] The cylindrical casing in this embodiment is made of stainless steel, which has good strength and good corrosion resistance, and can ensure the service life of the sensor. Of course, the cylindrical casing can also be made of other materials in different embodiments.

[0022] In the present embodiment, th...

Abstract

The invention discloses a tilt angle sensor for landslide measurement and a use method thereof; the tilt angle sensor for landslide measurement comprises a cylindrical shell, an inner cavity of the cylindrical shell is filled with a liquid, the cylinder opening end of the cylindrical shell is connected with a sensor seat, and the sensor seat is provided with a CCD camera; the use method of the tilt angle sensor for landslide measurement comprises the steps: drilling a rock-soil body where landslide possibly occurs; installing an inclination angle sensor for landslide measurement on an inclinometer pipe and then placing the inclinometer pipe at the bottom of the drill hole; connecting data lines of all sensors to a terminal to obtain initial angle data; switching on a power supply again atset intervals, and recording output data of all the sensors to obtain actual angle data of the time period; and calculating to obtain the horizontal displacement of the whole landslide body by utilizing the actual angle data measured in each time period. The technical problem that in the prior art, when an electronic compass is adopted for measuring landslide displacement of a landslide body containing ferromagnetic interference, errors are large, and even wrong results can be obtained is solved.

Description

technical field [0001] The invention relates to the technical field of landslide measurement, in particular to a sensor capable of real-time measurement of the displacement of a landslide body and a use method thereof. Background technique [0002] my country is a landslide-prone country. Landslide disasters often cause destructive disasters such as casualties, road burial, and house damage, which seriously threaten the life and property safety of the country and the people. Therefore, real-time monitoring of the deep displacement of landslides is very important. In the common landslide displacement monitoring methods, multiple groups of angle or displacement sensors are embedded in the landslide body for real-time measurement, and the real-time changes of the landslide displacement can be obtained by further calculation using the measurement data, and the angle sensors used here are basically Electronic compass, electronic compass will have data distortion in the case of e...
