5. The method of claim 4, wherein determining the activity state of the user in the vicinity of the smart home device based on the detected changes in the location coordinates and the detected changes in the temperature comprises:
the method comprises the steps of detecting that the distance between a current user and the intelligent household electrical appliance is smaller than the distance between the previous user and the intelligent household electrical appliance, detecting that the temperature in a set area around the user is increased in the process, determining that the user is close to and gazes at the liquid crystal display screen when the increased temperature is larger than or equal to a second amplitude value.
6. The method of claim 1, wherein the first and second light periods are each between 25s and 50 s.
7. An air conditioner, comprising:
the control chip is arranged in the air conditioner, and the pyroelectric infrared sensor and the liquid crystal display screen are connected with the control chip;
the pyroelectric infrared sensor is used for detecting a position signal and a temperature signal of a user in real time and sending the position signal and the temperature signal to the control chip;
the control chip is used for receiving a position signal and a temperature signal of a user, analyzing and calculating the position signal and the temperature signal in real time, and controlling to lighten the liquid crystal display screen after determining that the user moves close to and/or watches the liquid crystal display screen;
and the control chip is also used for controlling the liquid crystal display screen to be lightened to the brightness of one fourth of the standard brightness when detecting that the user moves but does not approach and watch the liquid crystal display screen, and closing the display after the preset second light-on duration.
8. An intelligent home appliance device, comprising:
the control chip is arranged in the intelligent household appliance, and the pyroelectric infrared sensor and the liquid crystal display screen are connected with the control chip;
