Description

An automatic multi-channel dual-axis inclination calibration platform, system and method

Technical Field

The present invention relates to the technical field of inclination calibration, and in particular to an automatic multi-channel dual-axis inclination calibration platform, system and method.

Background technique

The inclination module is a product used to measure the inclination angle of an object. Its main components include an inclination sensor, an MCU, a power supply, a communication part, and a housing. When the user uses it, the module is fixed to the surface of the object to be measured. When the object to be measured tilts at a certain angle, the user can read its inclination angle through the communication interface of the inclination module. The inclination module needs to be calibrated before leaving the factory. The so-called calibration of the inclination module is to use the inclination angle generated by a high-precision dividing head as the input of the inclination sensor to obtain the output of the inclination sensor, and then the MCU uses mathematical methods to determine the functional relationship between the output and the corresponding angle. That is, the process of calibrating the inclination module using a standard instrument with a higher level of accuracy. 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 indicators must be calibrated and tested to ensure the accurate transmission of the value. Generally, the calibration of inclination modules is mostly done manually. The basic idea is to fix a inclination module to be tested on a calibration platform, manually adjust the angle between the inclination module and the horizontal plane, manually collect the output of the inclination sensor at different angles to the MCU, and then obtain the functional relationship between the output and the corresponding angle to complete the calibration. This calibration method not only requires manual angle switching operations, but also can only calibrate single-axis inclination modules. When the other axis of the dual-axis inclination module needs to be calibrated, it must be removed and installed 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 is in urgent need of improvement.

Currently, no effective solution has been proposed for the problems in the related technologies.

As shown in FIG10 , according to an embodiment of the present invention, an automatic multi-channel dual-axis tilt calibration method is also provided, and the method comprises the following steps:

Step S101, switching the multi-way switch 12, reading the product model and serial number of each inclination module 4 to be calibrated and the calibration range, calibration points and single-axis and double-axis information of the corresponding product in the database;

Step S102, calibrating each of the inclination modules 4 to be calibrated;

Step S105, the single-axis calibration of the tilt module 4 is completed;

Step S106, if dual-axis calibration is required, the dual-axis angle rotation platform 7 rotates the second rotation module 2 90 degrees clockwise or counterclockwise for calibration;

Step S107: if the dual-axis calibration is not required, the calibration is terminated and the multi-way switch 12 is switched to save the calibration data of each module.

Working principle: In specific applications, the first intermittent divider 8 and the first servo motor 9 constitute a first rotating module 1, the second intermittent divider 10 and the second servo motor 11 constitute a second rotating module 2, the first rotating module 1 where the first intermittent divider 8 is located is responsible for rotating around the y-axis, and the second rotating module 2 where the second intermittent divider 10 is located is responsible for rotating around the z-axis. The first rotating module 1 is connected through a central axis and a groove jig, and the second rotating module 2 is installed on the groove jig, so that the calibration of the two axes of the inclination mold 4 can be achieved.

First, multiple inclination modules 4 to be calibrated are fixed on the dual-axis angle rotation platform 7 with the inclination module fixture 3, and the inclination module 4 is connected to the multi-way switch 12 with a data line.

After the hardware connection is completed, the calibration begins. The model of the current inclination module 4 to be calibrated is written through the PC host computer. According to the calibration requirements of the inclination module 4, the host computer 13 rotates the first rotation module 1 of the dual-axis angle rotation platform 7 to a certain angle through a command, and then the multi-way switch 12 switches the data path between the inclination module 4 and the PC, writes the current calibrated angle data into the inclination module connected to the channel through a command, and then switches other channels to write the same data respectively. Next, the host computer 13 controls the rotating platform to move to the next calibration angle position through commands, and the multi-way switch 12 switches the channel. The host computer 13 writes the data into the module, repeats the above actions, and finally saves the data to complete the calibration.
