Description

Technical Field

[0001] The invention belongs to the technical field of photoelectric sensors, and in particular relates to an intelligent calibration auxiliary device for photoelectric sensors. Background Art

[0002] In the field of industrial automation and precision measurement, photoelectric sensors are an important detection tool and are widely used in position detection, speed measurement, object recognition and other aspects. The working principle of photoelectric sensors is based on the photoelectric effect, which senses the changes in physical quantities in the external environment by measuring the changes in light signals. However, due to process differences in the manufacturing process, changes in environmental factors, and wear and tear during use, photoelectric sensors need to be calibrated before being put into use to ensure the accuracy and reliability of their measurement results.

[0003] The traditional photoelectric sensor calibration method usually uses a preset moving object as the object to be measured, adjusts the distance between the object and the photoelectric sensor, and records the corresponding photoelectric sensor detection voltage. This method requires the operator to calibrate each photoelectric sensor one by one, which is not only cumbersome and inefficient, but also difficult to ensure the accuracy of the calibration. In addition, due to differences in the technical level and operating habits of different operators, the calibration results may be inconsistent and uncertain.

[0004] In view of the above problems, it is particularly important to develop an intelligent calibration auxiliary device for photoelectric sensors. This device can realize the simultaneous calibration of multiple photoelectric sensors, simplify the calibration process, and improve the calibration efficiency and accuracy. At the same time, the intelligent calibration auxiliary device can also provide operators with real-time feedback and calibration suggestions on the calibration results by automatically recording and analyzing the calibration data, further reducing the difficulty of operation and improving the reliability and consistency of calibration. Therefore, the research and development of intelligent and automated photoelectric sensor calibration auxiliary devices has important practical significance and application prospects.
