Problems solved by technology

[0002] The sensitivity of the photoelectric sensor is usually adjusted by an external adjustable rotation, but some places have relatively high requirements for the sensitivity of the sensor. Too high or too low sensitivity will affect the use, such as the safety bottom edge of industrial doors, if the adjustment is too high or If it is too low, it will affect the use of industrial doors; in addition, when the photoelectric sensor is used for a long time, it will have a certain attenuation, and the sensitivity often needs to be manually adjusted regularly, which requires professionals to regularly go to the site for maintenance and increase the cost of use. For this reason, we A strong self-calibration photoelectric sensor and its application method are designed to solve the above problems

Abstract

The invention discloses a strong self-correction photoelectric sensor and a using method thereof. The sensor comprises a sensor body, wherein the sensor body comprises a sensor shell, a circuit boardis arranged in the sensor shell, one side of the circuit board is connected with a transmitting and receiving tube, the transmitting and receiving tube comprises a transmitting end and a receiving end, the transmitting end comprises a D1 transmitting tube, the D1 transmitting tube is an infrared transmitting tube, and the D1 transmitting tube comprises three pulse signals of transmitting 1, transmitting 2 and transmitting 3. According to the invention, the transmitting end adopts three groups of pulse signals with different frequencies to adjust the transmitting power, and when the device is used, the receiving end can inform the transmitting end to transmit the pulse signals with different frequencies according to different distances, and after a product is electrified each time, the sensor can automatically adjust the transmitting power of the product, so that the optimal sensitivity is realized, and convenience is brought to use.
