Abstract

The invention provides a diffuse reflection type photoelectric sensor anti-interference method and device and a medium, and the method comprises the steps: enabling a target sensor to obtain the transmitting end frequency of an adjacent photoelectric sensor, and enabling the target photoelectric sensor to set the transmitting end frequency of the target photoelectric sensor according to the transmitting end frequency of the adjacent photoelectric sensor, the frequency of the transmitting end is inconsistent with that of the transmitting end of the adjacent photoelectric sensor; it can be known that the transmitting end of the photoelectric sensor can be controlled to work at different frequencies, mutual interference of signal frequencies caused by abnormal frequencies of the transmitting end of the photoelectric sensor can be avoided, and the working accuracy and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent sensors, in particular to an anti-interference method, equipment and medium of a diffuse reflection photoelectric sensor. Background technique [0002] At present, in many scenarios of photoelectric sensors, the installation distance is often controlled to avoid mutual interference of multiple photoelectric sensors. [0003] In the prior art, the diffuse reflection photoelectric sensor is a photoelectric product with the transmitter and the receiver on the same side. It mainly uses light as the medium to receive and convert the light between the light emitting body and the light receiving body. Two diffuse reflection photoelectric sensors use different signal frequencies to avoid mutual interference, but there are the following problems: [0004] (1) It is necessary to set the signal frequency of each diffuse reflection photoelectric sensor to avoid mutual interference of signal frequencies, ...

AI Technical Summary

Problems solved by technology

[0004] (1) It is necessary to set the signal frequency of each diffuse reflection photoelectric sensor to avoid mutual interference of signal frequencies, but it will lead to complicated calculation and debugging, and low work efficiency;

[0005] (2) When the detection time slice difference of two adjacent diffuse reflection photoelectric sensors affects the signal frequency difference of two adjacent through-beam photoelectric sensors, so that the signal frequencies of the two diffuse reflection photoelectric sensors are mutually When disturbed, the accuracy and efficiency of the work will be reduced
