Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor believes that in the production and processing, the parameters of each component of the photoelectric sensor will be different, and the difference between the components will cause the detection voltage of the photoelectric sensor to have a deviation of tens to hundreds of millivolts from the threshold voltage. Defects that lead to poor consistency of photoelectric sensors

Embodiment Construction

[0045] In order to make the purpose, technical solutions and advantages of the present application, the following combined figure 1 And examples are described in further detail purposes of this application. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0046] When the photoelectric sensor is induced by the detection in its detection, the detecting material is separated from the optical signal emitted by the photoelectric sensor, and the photoelectric sensor receives the reflected light reflected by the detector, and is converted to the detection voltage in the photoelectric sensor. The photoelectric sensor has a potentiometer and a potentiometer for setting the threshold voltage of the photoelectric sensor. When the detection voltage is received, the detecting voltage is compared to the threshold voltage, and the comparison result of the detection voltag...

Abstract

The invention relates to the technical field of sensor calibration, in particular to a photoelectric sensor calibration method and system, a photoelectric sensor and a readable storage medium, and the method comprises the following steps: obtaining a detection voltage; acquiring a threshold voltage; normalizing and converting the detection voltage and the threshold voltage into voltage variation; and when the detection voltage is the same as the threshold voltage in variation, outputting a response signal. The photoelectric sensor is convenient to calibrate, and the consistency of the photoelectric sensor is improved.

Description

Technical field [0001] The present application relates to the technical field of sensor calibration, in particular, to photoelectric sensor calibration methods, systems, photoelectric sensors, and readable storage media. Background technique [0002] The photoelectric sensor is a device that converts the optical signal into an electrical signal. When the detector is within the detection range of the photoelectric sensor, the photoelectric sensor receives the reflected light returned by the detector and converts the reflected light to the detection voltage, when the detection voltage is When the preset threshold voltage (reference voltage) of the photoelectric sensor is equal, the photoelectric sensor outputs a response signal, and the threshold voltage of the photoelectric sensor is set by the potentiometer is set thereon. [0003] In response to the above-described related art, the inventors believe that there is a difference in the parameters of each component of the photoelect...
