Intelligent wearable device and power supply method for intelligent wearable device

A power supply method implemented by an intelligent wearable device, wherein the method comprises:

• detecting an output voltage of a battery-powered circuit of the intelligent wearable device while the intelligent wearable device is worn;
• controlling a non-basic functional circuit of the intelligent wearable device to stop working when the output voltage is less than a preset first voltage threshold, wherein the output voltage being less than the preset first voltage threshold indicates the battery-powered circuit does not output a current;
• controlling a self-powered circuit of the intelligent wearable device to supply power to a basic functional circuit of the intelligent wearable device when the output voltage is less than the preset first voltage threshold;
• disabling the battery-powered circuit when the output voltage is less than the preset first voltage threshold, wherein disabling the battery-powered circuit when the output voltage is less than the preset first voltage threshold prevents a reverse current flowing from the self-powered circuit to the battery-powered circuit;
• and
• controlling a self-powered circuit and the battery-powered circuit to supply power to the basic functional circuit and the non-basic functional circuit when the output voltage is greater than or equal to the preset first voltage threshold, wherein the self-powered circuit continuously generates the power while the intelligent wearable device is worn, wherein the self-powered circuit does not supply the power to the battery-powered circuit while the self-powered circuit generates the power, wherein the basic functional circuit is configured to complete a main function of the intelligent wearable device, and wherein the non-basic functional circuit is configured to complete another function other than the main function of the intelligent wearable device.
