Problems solved by technology
[0002] The inclinometer is one of the main instruments for structural deformation measurement. It has been widely used in projects such as high slopes and dams, but the calibration problem of the inclinometer has always been difficult to solve.
The current calibration methods are obtained by using a cuboid block and manual positioning calculation with calipers. It is difficult to consider the mutual influence of the X and Y directions, and it is impossible to test the influence of the axis torsion of the inclinometer on the output. The human error is large. The calibration accuracy is low and the operation is cumbersome

Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0035] Such as figure 1 and 2 As shown, an automatic calibration device for an inclinometer includes a horizontal plane calibration unit and a vertical plane calibration unit; the horizontal plane calibration unit includes a horizontal turntable 6 and a vertical axis drive servo motor that drives the horizontal turntable 6 to rotate in the horizontal plane 7. The vertical surface calibration unit is arranged on the horizontal turntable 6 and rotates with the rotation of the horizontal turntable 6. The vertical surface calibration unit includes the fixed runner 3 of the inclinometer and drives the fixed runner 3 of the inclinometer on the vertical surface. The internally rotating horizontal sha...

The invention discloses an automatic calibrating device and calibrating method for an inclinometer. The device includes a horizontal plane calibrating unit and a vertical plane calibrating unit; Shaft-driven servo motor; the vertical plane calibration unit is set on the horizontal turntable and rotates with the rotation of the horizontal turntable, including the fixed wheel of the inclinometer and the horizontal axis drive servo that drives the fixed wheel of the inclinometer to rotate in the vertical plane The motor and the inclinometer fixed wheel are provided with an inclinometer rod fixing hole for installing the inclinometer rod; the axis of the horizontal turntable, the axis of the inclinometer fixed wheel and the axis of the inclinometer rod always intersect at one point, Automatic calibration is realized by controlling two servo motors to advance and retreat at a certain angle and measuring the output of the inclinometer. The invention can realize the automatic calibration of the full attitude, the full range and the full performance index of the inclinometer, the calibration device is reliable, and the calibration method is simple, accurate and efficient.
Description
technical field [0001] The invention belongs to the technical field of calibrating devices, and in particular relates to an automatic calibrating device and calibrating method for an inclinometer. Background technique [0002] The inclinometer is one of the main instruments for structural deformation measurement. It has been widely used in high slopes, embankments and other projects, but the calibration problem of the inclinometer has always been difficult to solve. The current calibration methods are obtained by using a cuboid block and manual positioning calculation with calipers. It is difficult to consider the mutual influence of the X and Y directions, and it is impossible to test the influence of the axis torsion of the inclinometer on the output. The human error is large. The calibration accuracy is low and the operation is cumbersome. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provid...
