Abstract

The invention relates to television remote control equipment based on audience state detection. The television remote control equipment is hung on a roof between the audience and a television and comprises an infrared remote control switch, an image collector, an image processor and an AT89C51 singlechip microcomputer, wherein the infrared remote control switch is used for controlling the television to be turned on and off; the image collector is used for collecting a facial image of the audience; the image processor is connected with the image collector for processing the facial image of the audience; the singlechip microcomputer and the infrared remote control switch are respectively connected with the image processor to control the infrared remote control switch based on an image processing result. Through the television remote control equipment provided by the invention, whether the television is automatically turned off or not is determined according to the fact that whether the audience is in a sleep state or not when the television is in an operating state, so that a quiet sleeping environment is given to the audience while the energy source is saved.
