Abstract

The present invention provides a diffuse reflection photoelectric sensor anti-jamming method, equipment and medium. The method includes: the target sensor obtains the frequency of the transmitting end of the adjacent photoelectric sensor, and according to the frequency of the transmitting end of the adjacent photoelectric sensor, the target photoelectric sensor sets The frequency of the transmitting end of itself makes it inconsistent with the frequency of the transmitting end of the adjacent photoelectric sensor; it can be seen that the present invention can control the frequency of the transmitting end of the photoelectric sensor to work at different frequencies, and can avoid the abnormal frequency of the transmitting end of the photoelectric sensor, resulting in signal frequency Mutual interference, improve work accuracy and efficiency.

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, photoelectric sensors often control the installation distance to avoid mutual interference of multiple photoelectric sensors. [0003] In the prior art, the diffuse reflection photoelectric sensor is an optoelectronic 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. The 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, but it ...
