Abstract

A home gateway system having a power management function includes function modules for controlling electrical/electronic products at home by function and a power supply for supplying electrical power to the function modules. The home gateway system further includes a signal input unit for externally receiving a control signal; a control unit for generating a power control signal for controlling the power applied to the respective function modules in response to the control signal, generating a standby setting signal for setting the respective function modules into a standby state, and selectively applying the standby setting signal to the respective function modules; and a power switching unit for turning the respective function modules on or off in response to the power control signal. Accordingly, the home gateway system can selectively turn off or on individual function modules, and set or release inactive function modules to or from the standby state.

Claims

1. A home gateway system having a power management function that includes one or more function modules for controlling electrical and electronic products at home by function and a power supply for supplying electric power to the one or more function modules, comprising:

a signal input unit for externally receiving a control signal;

a control unit for generating a power control signal for controlling the power applied to respective ones of the function modules in response to the control signal, generating a standby setting signal for setting the respective function modules to a standby state, and selectively applying the standby setting signal to the respective function modules; and

a power switching unit for turning the respective function modules on or off in response to the power control signal.

2. The home gateway system as claimed in claim 1, wherein the control unit includes:

a monitoring unit for selectively applying the power control signal to the respective function modules in response to the control signal and checking operation states of the respective function modules in a predetermined time interval; and

a standby control unit for applying the standby setting signal to function modules selected based on a result of the check of the monitoring unit and the control signal applied to the signal input unit.

3. The home gateway system as claimed in claim 2, wherein the control unit has one or more driver programs for driving the respective function modules, and the driver programs are applied to the selected function modules together with the standby setting signal.

4. The home gateway system as claimed in claim 2, wherein each of the function modules has a register for setting an operation condition thereof, the driver programs are loaded into the control unit, the standby setting signal is applied to the registers of the selected function modules, and the selected function modules are set to a standby state.

5. The home gateway system as claimed in claim 1, wherein the control signal is externally generated by one of a wired control device and a wireless control device.

6. The home gateway system as claimed in claim 5, wherein the wired control device is at least one of a power setting key provided for each of the function modules and a remote personal computer for controlling the function modules through a network.

7. The home gateway system as claimed in claim 5, wherein the wireless control device is at least one of a remote controller, a mobile electronic device, and a remote personal computer for controlling the function modules through a wireless network.

8. A power control method for a home gateway system having at least one function module for controlling electrical and electronic products at home by function and a power supply for supplying electric power to the function modules, comprising:

receiving a control signal externally;

generating a standby setting signal corresponding to the control signal; and

selectively applying the standby setting signal to the function modules.

9. The power control method as claimed in claim 8, wherein the operation of generating the standby setting signal further includes:

checking an operation state of each of the function modules in a predetermined time interval; and

applying the standby setting signal to any inactive function modules of the checked function modules according to a result of the check.

10. A power control method for a home gateway system having at least one function module for controlling electrical and electronic products at home by function and a power supply for supplying electric power to the function modules, comprising:

receiving a control signal externally;

generating a power signal corresponding to the control signal; and

selectively applying the power signal to the function modules.

11. The power control method as claimed in claim 10, wherein application of the power signal causes a function module to be turned off.

12. The power control method as claimed in claim 10, wherein application of the power signal causes a function module to be turned on.
