Smart socket control method and system

The invention discloses a smart socket control method and system. The method includes presetting an alarm distance of a high-voltage device; obtaining an actual distance from a human body to the high-voltage device based on an ultrasonic sensor; calculating the magnitude relation and the positive-negative relation of the actual distance and the alarm distance, and generating a loudspeaker controlinstruction and a safety power strip control instruction based on the magnitude relation and the positive-negative relation; transmitting the loudspeaker control instruction to a loudspeaker so that the loudspeaker gives an alarm or stops operating according to the loudspeaker control instruction; transmitting the safety power strip control instruction to a safety power strip so that the safety power strip is powered off or powered on in accordance with the power strip control instruction so as to power off or power on the high-voltage device powered by the safety power strip. The smart socketcontrol method can be app
