Abstract

The invention discloses an inclinometer pipe-free omnibearing self-correction real-time displacement measuring tube. An inclinometer is arranged in a tube body, a triaxial accelerograph, a triaxial gyroscope and a triaxial magnetometer are arranged on the inclinometer; the triaxial accelerograph and the triaxial gyroscope are connected with a KALMAN filter, and an included angle of the whole in the horizontal direction is obtained by the accelerograph and the gyroscope by virtue of the KALMAN filter; the triaxial magnetometer is connected with the KALMAN filter, and the magnetometer and the included angle in the horizontal direction are synthesized, so that a position of the whole in a geodetic coordinate system, namely a rotation matrix, is obtained. The inclinometer pipe-free omnibearingself-correction real-time displacement measuring tube disclosed by the invention has the advantages that an inclinometer pipe is eliminated, and structure principle of a monitor is completely different from that of the traditional clinometers; and displacement can be immediately, accurately and continuously measured in an omnibearing way.

Description

technical field [0001] The invention relates to a displacement measuring tube. Background technique [0002] Internal displacement monitoring is extremely important in geotechnical constructions such as earth-stone walls, panel walls, rock slopes, and civil foundation pits. At present, the common method of monitoring this displacement is to install high-precision inclinometer pipes during the construction process, or to drill and sink inclinometer pipes. Then introduce the inclinometer into the inclinometer tube to monitor the internal displacement of the measured object in points, time and segments. This monitoring must rely on the inclinometer tube, and the installation state of the inclinometer tube will directly affect the accuracy of the inclinometer. The ability to obtain the real displacement inside the measured object largely depends on the accuracy of the inclinometer tube. Contents of the invention [0003] The purpose of the present invention is to provide a ...
