Description

An automatic multi-channel dual-axis inclination calibration platform

technical field

The utility model relates to the technical field of inclination calibration, in particular to an automatic multi-channel dual-axis inclination calibration platform.

Background technique

The inclination module is a product used to measure the inclination angle of an object. Its main components include inclination sensor, MCU, power supply part, communication part and shell. When the user uses it, fix the module on the surface of the measured object. When the measured object is inclined at a certain angle, the user can read the inclination angle through the communication interface of the inclination module. The inclination module needs to be calibrated when it leaves the factory. The so-called calibration of the inclination module uses the inclination angle generated by the high-precision dividing head as the input of the inclination sensor to obtain the output of the inclination sensor. Then the MCU uses mathematical methods to determine The process of the functional relationship between the output and the corresponding angle. That is to say, the process of using the standard instruments with higher precision to calibrate the inclination module. In this way, when the inclination module (or the built-in inclination sensor) tilts at a certain angle, the MCU part of the inclination module reads the output of the inclination sensor, obtains the corresponding angle through the functional relationship, and outputs it to the communication part. After the inclination module is manufactured and assembled, the design index must be calibrated to ensure the accurate transmission of the value. Generally, the calibration of the inclination module is mostly done manually. The basic idea is to fix an inclination module to be measured on the calibration platform, manually adjust the angle between the inclination module and the horizontal plane, and manually collect the output of the inclination sensor at different angles to the MCU, and then get the output The function relationship between the quantity and the corresponding angle is used to complete the calibration. This calibration method not only requires manual operation of switching angles, but also can only calibrate the single-axis inclination module. When the other axis of the two-axis inclination module needs to be calibrated, remove it and install it on the calibration platform in another direction to continue calibration. The operation is complicated and time-consuming. This single-module serial calibration method is difficult to meet the mass production of inclination modules in mass production, and needs to be improved urgently.
