Keyboard with facial recognition function

Abstract

The invention discloses a keyboard with a facial recognition function. The keyboard with the facial recognition function comprises a keyboard body, wherein a camera device, s light sensor, a buzzer, a wireless communication transceiver, a dynamic light compensation circuit, a single-chip microcomputer, a PWM (Pulse Width Modulation) control circuit and an infrared LED (Light Emitting Diode) lamp bank are arranged on the keyboard body, the data output end of the camera device and the data output end of the light sensor are respectively connected with the data input end of the single-chip microcomputer, the data output end of the single-chip microcomputer is connected with the data input end of the wireless communication transceiver, the control output end of the single-chip microcomputer is connected with the control input end of the buzzer and the control input end of the dynamic light compensation circuit, the output end of the dynamic light compensation circuit is connected with the input end of the PWM control circuit and the output end of the PWM control circuit is connected with the input end of the infrared LED lamp bank. The keyboard with the facial recognition function realizes facial recognition verification through the camera device arranged on the keyboard, the buzzer is controlled to give out a prompt to remind an operator to leave an operating position when the verification fails, and the structure is simple.
