Method and device for turning on air conditioner

A device for turning on an air conditioner, comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor,
• wherein the processer is configured to:
• acquire a sensor parameter collected by a wearable device;
• determine a physiological parameter based on the sensor parameter;
• determine a change in a sleep state of a user wearing the wearable device based on the physiological parameter, wherein the sleep state comprises at least a deep sleep state and a light sleep state;
• detect whether the change in the sleep state is in conformity with a predetermined condition, wherein the predetermined condition comprises a transition from the deep sleep state to the light sleep state;
• and
• turn on the air conditioner when the change in the sleep state is detected to be in conformity with the predetermined condition,
• wherein the processer is further configured to determine an estimated length of time period t1 during which the user will be in the light sleep state prior to turning on the air conditioner, and
• the processer is further configured to:
• turn on the air conditioner immediately when the change in the sleep state is detected to be in conformity with the predetermined condition in the case of t1≤t2;
• and
• turn on the air conditioner after a time period (t1−t2) from the change in the sleep state being detected to be in conformity with the predetermined condition in the case of t1>t2,
• wherein t2 represents an estimated length of time period during which a room temperature will be adjusted to a target temperature by the air conditioner.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a device, cause the device to perform a method for turning on an air conditioner, the method comprising:

• acquiring a sensor parameter collected by a sensor in a wearable device;
• determining a physiological parameter based on the sensor parameter;
• determining a change in a sleep state of a user wearing the wearable device based on the physiological parameter, the sleep state at least comprising a deep sleep state and a light sleep state;
• detecting whether the change in the sleep state is in conformity with a predetermined condition, the predetermined condition comprising a transition from the deep sleep state to the light sleep state;
• and
• turning on the air conditioner when the change in the sleep state is detected to be in conformity with the predetermined condition,
• wherein prior to turning on the air conditioner, the method further comprises determining an estimated length of time period t1 during which the user will be in the light sleep state, and
• the turning on the air conditioner comprises:
• turning on the air conditioner immediately when the change in the sleep state is detected to be in conformity with the predetermined condition in the case of t1≤t2;
• and
• turning on the air conditioner after a time period (t1−t2) from the change in the sleep state being detected to be in conformity with the predetermined condition in the case of t1>t2,
• wherein t2 represents an estimated length of time period during which a room temperature will be adjusted to a target temperature by the air conditioner.
