Control method and device of intelligent IoT electrical appliances, and intelligent IoT electrical appliances

The invention provides a control method and device of intelligent IoT (Internet of Things) electrical appliances, and intelligent IoT electrical appliances. The method includes processes completed on any intelligent IoT electrical appliance side: analyzing received speech signals to obtain control instructions specific to a target intelligent IoT electrical appliance; recording the receiving intensity of the speech signals and notifying other intelligent IoT electrical appliances; according to the receiving intensity information of each intelligent IoT electrical appliance for the speech signals, determining whether an intelligent IoT electrical appliance is closest to the sound source of the speech signals; and executing the control instructions if the intelligent IoT electrical appliance is closest to the sound source of the speech signals. According to the invention, the interaction between an intelligent IoT electrical appliance and a user is more intelligent and convenient, and manual control operations and intelligent scene presetting can be reduced.
