Abstract

A matching system of an electronic device and a perpheral device and a matching method thereof are described. The system includes and electric device, having an identification mechanism for identifying a specific identification code and generating a control signal or a control instruction according to an identification result; and a peripheral device, electrically coupled to the electronic device selectively. The peripheral device includes an identification code unit for storing a group identification code; and a power control unit, for controlling an operation state of the peripheral device according to the control signal or the control instruction, when the peripheral device is electrically coupled to the electronic device. If the identification result is that the specific identification code is consistent with the group identification code, the power control unit controls the entire peripheral device to work normally according to the control signal or the control instruction.

Claims

1. A matching system of an electronic device and a peripheral device, comprising:

an electronic device, having an identification mechanism, for identifying a specific identification code, and generating a control signal or a control instruction according to an identification result; and

a peripheral device, electrically coupled to the electronic device selectively, comprising;

an identification code unit, for storing a group identification code; and

a power control unit, for controlling an operation state of the peripheral device according to the control signal or the control instruction, when the peripheral device is electrically coupled to the electronic device;

configured such that if the identification result is that the specific identification code is consistent with the group identification code, the power control unit controls the entire peripheral device to work normally according to the control signal or the control instruction.

2. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the identification mechanism is an embedded controller (EC).

3. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the identification mechanism is a software program.

4. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the peripheral device is a docking station having at least one signal input/output connection interface, for expanding a signal input/output connection interface of the electronic device.

5. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the peripheral device further comprises a power unit electrically coupled to the identification code unit, for supplying an electrical power required by operations of the identification code unit.

6. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the identification code unit is electrically coupled to the identification unit through a system management (SM) bus.

7. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein if the identification result is that the specific identification code is not consistent with the group identification code, the power control unit controls a part of the peripheral device to work normally according to the control signal or the control instruction.

8. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein if the identification result is that the specific identification code and the group identification code do not exist in the peripheral device, the power control unit controls the peripheral device to entirely stop working according to the control signal or the control instruction.

9. The matching system of an electronic device and a peripheral device as claimed in claim 1, wherein the identification unit continuously identifies the group identification code within a predetermined time period, so as to assure the matching system to work normally.

13. The matching system of an electronic device and a peripheral device as claimed in claim 1, configured such that the power control unit controls the entire peripheral device to work normally by turning on all of a plurality of power switches of the peripheral device.

14. The matching system of an electronic device and a peripheral device as claimed in claim 7, configured such that the power control unit controls part of the peripheral device to work normally by turning on some but not all of a plurality of power switches of the peripheral device.

15. The matching system of an electronic device and a peripheral device as claimed in claim 8, configured such that the power control unit controls the peripheral device to entirely stop working by turning off all of a plurality of power switches of the peripheral device.

10. A method for matching an electronic device with a peripheral device, comprising:

detecting whether a group identification code exists in the peripheral device or not by the electronic device, after the electronic device is electrically coupled to the peripheral device;

turning on a part of operation powers for the peripheral device, when the electronic device confirms that the group identification code exists; and

turning on all the operation powers for the peripheral device, when the electronic device confirms that the group identification code is consistent with a specific identification code.

11. The method for matching an electronic device with a peripheral device as claimed in claim 10, wherein when the electronic device confirms that the group identification code does not exist, all the operation powers for the peripheral device are turned off.

12. The method for matching an electronic device with a peripheral device as claimed in claim 10, wherein the electronic device detects the group identification code in the peripheral device through an SM bus.

16. A matching system of an electronic device and a peripheral device, comprising:

an electronic device, having an identification mechanism configured to identify a specific identification code and generate a control signal or a control instruction according to an identification result; and

a peripheral device, electrically coupled to the electronic device selectively, comprising;

an identification code unit storing a group identification code; and

a power control unit configured to control an operation state of the peripheral device according to the control signal or the control instruction when the peripheral device is electrically coupled to the electronic device;

configured such that if the identification result is that the specific identification code is consistent with the group identification code, the power control unit controls the entire peripheral device to work normally according to the control signal or the control instruction, and if the identification result is that the specific identification code is not consistent with the group identification code, the power control unit controls a part but not the entirety of the peripheral device to work normally according to the control signal or the control instruction, and if the identification result is that the specific identification code and the group identification code do not exist in the peripheral device, the power control unit controls the peripheral device to entirely stop working according to the control signal or the control instruction.

17. The matching system of an electronic device and a peripheral device as claimed in claim 16, configured such that the power control unit controls the entire peripheral device to work normally by turning on all of a plurality of power switches of the peripheral device.

18. The matching system of an electronic device and a peripheral device as claimed in claim 16, configured such that the power control unit controls part of the peripheral device to work normally by turning on some but not all of a plurality of power switches of the peripheral device.

19. The matching system of an electronic device and a peripheral device as claimed in claim 16, configured such that the power control unit controls the peripheral device to entirely stop working by turning off all of a plurality of power switches of the peripheral device.
