Abstract

The invention discloses an automatic calibration method for an inclinometer, which comprises the following steps of: firstly, reading a set series of numerical values through industrial personal computer software, and calculating to obtain the number of pulses for controlling a step motor; secondly, outputting a control pulse to a step motor controller through a data collecting card by an industrial personal computer, and further controlling the step motor to rotate a corresponding angle, and driving a detection platform and a round grating sensor to rotate through a mechanical transmission mechanism; then, sending the detected rotation angle to the industrial personal computer through the data collecting card in the form of pulse by the round grating sensor, comparing the rotation angle with a set angle, sending a stopping command by the industrial personal computer so that the motor stop rotating when the set value is reached, and inputting the reading of the inclinometer by a subscriber; and finally, analyzing by the software to obtain a calibrated equation and error. In the invention, the continuous high precision calibration of a distance-measuring range at multiple angles without limitation is realized, wherein the calibration precision can reach 3'', and the inclinometer is particularly suitable for the calibration of the inclinometer in inclinometer manufacturing enterprises, using units and metering technological organizations, and the like.

Description

technical field [0001] The invention relates to the field of industrial computer measurement and control, and is specifically used for the automatic generation of angles and automatic analysis and processing of data in the calibration of an inclinometer. Background technique [0002] The inclinometer is mainly used in the safety inspection of roads, bridges, dams and geotechnical engineering. It is suitable for coal mine engineering, geological drilling, anti-seepage grouting holes, pile core-pulling holes, geotechnical engineering measurement drilling and non-magnetic mines. It can also measure deep foundation pits, slopes, foundations, horizontal displacements and section settlements. [0003] The instrument uses an inclination sensor as a sensitive element, which is a force balance servo system. When the sensor probe has an inclination angle relative to the direction of the center of gravity of the earth, due to the action of gravity, the sensitive element in the sensor s...
