INFRARED HUMAN FACE DETECTION DEVICE AND METHOD FOR PHOTON BEAUTY APPARATUS

摘要

An infrared human face detection device for a photon beauty apparatus. The infrared human face detection device comprises: an infrared pair sensor (IR1), a level conversion module (1), a voltage comparison unit (2), an MCU module (3), and an LED photon module (4). The infrared pair sensor (IR1) is used for transmitting a face detection signal. The level conversion module (1) is used for shaping a signal, transmitted from an infrared receiver, to a standard level signal. The voltage comparison unit (2) is used for transmitting a triggering signal corresponding to the face detection signal. The MCU module (3) is used for transmitting a PWM pulse signal when receiving the triggering signal and for closing a transmission port thereof when not receiving the triggering signal. The PWM pulse signal drives the LED photon module (4) to generate a photon signal. The invention achieves automatic detection of a human face and automatically controls photon generation on the basis of a wearing status of the photon beauty apparatus.
