Abstract

A power management system for a device is provided. The power management system includes a functional module and a control module electrically connected with the functional module. The control module controls the functional module when a power status signal matches with a power threshold signal.

Claims

1. A power management system for a device, comprising:

a functional module; and

a control module electrically connected with the functional module and controlling the functional module when a power status signal matches with a power threshold signal.

2. A power management system according to claim 1, further comprising:

a basic input output system electrically connected with the control module;

a human machine interface electrically connected with the basic input output system and providing the power threshold signal to the control module via the basic input output system; and

a power monitoring module providing the power status signal to the control module.

3. A power management system according to claim 2, wherein the control module provides a first message to the human machine interface and then the human machine interface provides a second message to a user based on the first message.

4. A power management system according to claim 3, wherein the second message includes an information of an available amount of a power of the device and inquires whether the functional module should be powered off.

5. A power management system according to claim 1, wherein the functional module is a communication module.

6. A power management system according to claim 1, where the functional module is a voice-control module.

7. A power management system according to claim 1, wherein the functional module is a photography module.

8. A power management system according to claim 1, wherein the functional module is a music module.

9. A power management system according to claim 1, wherein the control module is used for powering off the functional module.

10. A method for managing a power of a device, comprising steps of:

a) providing a procedure;

b) providing a power status signal;

c) providing a power threshold signal corresponding to a functional module;

d) comparing the power status signal with the power threshold signal to obtain a comparison result; and

e) controlling the functional module based on the comparison result.

11. A method according to claim 10, wherein the functional module is powered off in the step e).

12. A method according to claim 10, further comprising steps of:

f) providing a human machine interface capable of providing the procedure and the power threshold signal;

g) providing a power monitoring module capable of providing the power status signal; and

h) providing a control module capable of performing the steps d) and e).

13. A method according to claim 10, further comprising steps of:

i) providing a first message to the human machine interface from the control module; and

j) providing a second message to a user from the human machine interface based on the first message.

14. A method according to claim 13, wherein the second message includes an information of an available amount of the power and inquires whether the functional module should be powered off.

15. A method according to claim 10, wherein the functional module is a communication module.

16. A method according to claim 10, where the functional module is a voice-control module.

17. A method according to claim 10, wherein the functional module is a photography module.

18. A method according to claim 10, wherein the functional module is a music module.

19. A method for managing a power of a device, comprising steps of:

a) setting a predetermined power threshold and a function corresponding to the predetermined power threshold;

b) monitoring the power for determining a power status;

c) comparing the power status with the power threshold to obtain a comparison result; and

d) performing the function based on the comparison result.

20. A method according to claim 19, wherein the function is performed by one selected from a group consisting of a communication module, a voice-control module, a photography module and a music module.
