[Abstract]:The inclinometer is used for measuring a plane (or cylindrical) relative to the horizontal plane and the tilt angle (or cylindrical) angle between the instrument, including the use of optical electronic tiltmeter tilt sensor electronic digital inclinometer and mechanical angle measuring mechanism. In this paper, a calibration device based on high precision angle encoder is studied and developed. First, the current research status of the calibration of the inclinometer at home and abroad is analyzed, and the common angle benchmarks are introduced, and the existing calibration devices are analyzed. According to the measuring principle of the inclinometer and the requirements of the calibration project, and drawing on the existing calibration methods and devices, the scheme of the calibration device is determined. Design manual calibration device, according to the characteristics of the required calibration datum instruments of the selected angle encoder for the calibration device and calibration datum instruments, according to the requirements of the project, the selected angle encoder model through angle coder and inclinometer data, realize the calibration. According to the size, shape and angle of the inclinometer, the installation, size and shape of the encoder are designed, and a manual device is designed. The device includes mechanical system, angle encoder and display. According to the design scheme to determine the mechanical system, the mechanical system includes: fixture parts, clamp for calibration of the inclinometer component installed on the drive components are angle encoder and speed components on the regulation of angle encoder and the base member of the leveling device, then each part to analyze and design, determine the structure of the part. We use SolidWorks software to design mechanical mechanism assembly drawing, draw parts engineering drawings, make parts processing, and then assemble parts to complete the development of manual calibration device. According to the requirements of the users of the device, the design of the improved device is carried out on the basis of the manual device. The motor is used as the driving part to drive the operation of the mechanical parts. The AT89S52 microcontroller is used as the slave computer, and the upper computer software is designed by LabVIEW to control the motor. Application of Lab module VIEW read and record with the inclination angle encoder output interface and open, no output interface or output interface but not with the inclinator open the camera to capture images and identify the image data, and recording data, complete the development of improved device. Finally, the calibration device is calibrated and the calibration certificate is obtained. The manual calibration is used to calibrate the inclinometer, and the experimental data are recorded and analyzed to get the calibration results.
