Abstract

A method for controlling a power strip includes: acquiring a present temperature parameter of an ambient environment; determining a presently-allowed maximum power of the power strip based on the present temperature parameter; acquiring a total power of electronic devices presently powered by the power strip; and controlling the power strip to cut off power supply to at least one of the electronic devices when the total power is greater than the presently-allowed maximum power. In the technical solution, the presently-allowed maximum power of the power strip can be adjusted automatically based on the present temperature parameter of the ambient environment of the power strip, which improves flexibility of adjusting the maximum power.

First claim

The invention claimed is:

1. A method for controlling a power strip, comprising:
acquiring a present temperature parameter of an ambient environment;
determining a presently-allowed maximum power of the power strip based on the present temperature parameter, comprising:
determining a previously-determined maximum power as the presently-allowed maximum power of the power strip when a difference between the present temperature parameter of the ambient environment and a temperature parameter corresponding to the previously-determined maximum power is less than or equal to a preset threshold; and
adjusting the presently-allowed maximum power of the power strip in a preset adjustment manner when the difference between the present temperature parameter of the ambient environment and the temperature parameter corresponding to the previously-determined maximum power is greater than the preset threshold;

acquiring a total power of electronic devices presently powered by the power strip; and
controlling the power strip to cut off power supply to at least one of the electronic devices when the total power is greater than the presently-allowed maximum power.

2. The method according to claim 1 , wherein determining the presently-allowed maximum power of the power strip based on the present temperature parameter comprises:
determining the presently-allowed maximum power of the power strip at the present temperature parameter according to a preset correspondence between a temperature parameter and an allowed maximum power,
wherein the preset correspondence between the temperature parameter and the allowed maximum power is a negative correlation.

3. The method according to claim 1 , wherein the preset adjustment manner comprises:
when the present temperature parameter is increased by a preset temperature with respect to the temperature parameter corresponding to the previously-determined maximum power, the presently-allowed maximum power is decreased by a preset power with respect to the previously-determined maximum power; and
when the present temperature parameter is decreased by a preset temperature with respect to the temperature parameter corresponding to the previously-determined maximum power, the presently-allowed maximum power is increased by a preset power with respect to the previously-determined maximum power.

4. The method according to claim 1 , wherein controlling the power strip to cut off power supply to the at least one of the electronic devices comprises:
controlling the power strip to cut off power supply to a recently-powered electronic device of the electronic devices.

5. The method according to claim 1 , further comprising:
outputting, when the total power is greater than the presently-allowed maximum power, prompt information for prompting a user that the power strip has an excessive power.

6. A device for controlling a power strip, comprising:
a processor; and
a memory for storing instructions executable by the processor,
wherein the processor is configured to:
acquire a present temperature parameter of an ambient environment;
determine a presently-allowed maximum power of the power strip based on the present temperature parameter, wherein determining the presently-allowed maximum power of the power strip comprises:
determining a previously-determined maximum power as the presently-allowed maximum power of the power strip when a difference between the present temperature parameter of the ambient environment and a temperature parameter corresponding to the previously-determined maximum power is less than or equal to a preset threshold; and
adjusting the presently-allowed maximum power of the power strip in a preset adjustment manner when the difference between the present temperature parameter of the ambient environment and the temperature parameter corresponding to the previously-determined maximum power is greater than the preset threshold;

acquire a total power of electronic devices presently powered by the power strip; and
control the power strip to cut off power supply to at least one of the electronic devices when the total power is greater than the presently-allowed maximum power.

7. The device according to claim 6 , wherein the processor is further configured to:
determine the presently-allowed maximum power of the power strip at the present temperature parameter according to a preset correspondence between a temperature parameter and an allowed maximum power,
wherein the preset correspondence between the temperature parameter and the allowed maximum power is a negative correlation.

8. The device according to claim 6 , wherein preset adjustment manner comprises:
when the present temperature parameter is increased by a preset temperature with respect to the temperature parameter corresponding to the previously-determined maximum power, the presently-allowed maximum power is decreased by a preset power with respect to the previously-determined maximum power; and
when the present temperature parameter is decreased by a preset temperature with respect to the temperature parameter corresponding to the previously-determined maximum power, the presently-allowed maximum power is increased by a preset power with respect to the previously-determined maximum power.

9. The device according to claim 6 , wherein controlling the power strip to cut off power supply to at least one of the electronic devices comprises:
controlling the power strip to cut off power supply to a recently-powered electronic device of the electronic devices.

10. The device according to claim 6 , wherein the processor is further configured to:
output, when the total power is greater than the presently-allowed maximum power, prompt information for prompting a user that the power strip has an excessive power.

11. 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 controlling a power strip, the method comprising:
acquiring a present temperature parameter of an ambient environment;
determining a presently-allowed maximum power of the power strip based on the present temperature parameter, comprising:
determining a previously-determined maximum power as the presently-allowed maximum power of the power strip when a difference between the present temperature parameter of the ambient environment and a temperature parameter corresponding to the previously-determined maximum power is less than or equal to a preset threshold; and

acquiring a total power of electronic devices presently powered by the power strip; and
controlling the power strip to cut off power supply to at least one of the electronic devices when the total power is greater than the presently-allowed maximum power.

12. The non-transitory computer-readable storage medium according to claim 11 , wherein determining the presently-allowed maximum power of the power strip based on the present temperature parameter comprises:
determining the presently-allowed maximum power of the power strip at the present temperature parameter according to a preset correspondence between a temperature parameter and an allowed maximum power,
wherein the preset correspondence between the temperature parameter and the allowed maximum power is a negative correlation.
