Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of an apparatus for reducing standby power in an electrical outlet according to an embodiment of the present invention.

Referring to FIG. 1, the standby power saving apparatus 100 is equal to standby power in which active power consumed by one or more electronic devices (not shown) that receives power supplied from the power output unit 150 is preset. It is a device that automatically cuts off the power to the electronic device when it is lower than standby power. In the present specification, the standby power refers to active power consumed when the electronic device does not perform a main function or is waiting for a command to perform the main function while connected to an external power source. Standby power may be determined by detecting active power consumed by an electronic device in a standby state or may be determined by a user (via an interface or through a communication network). A detailed method of determining the standby power will be described later.

The standby power saving apparatus 100 according to an embodiment of the present invention includes a power detector 110 and a controller 130, and includes a power input unit 105, a switch unit 140, a power output unit 150, and a user. The interface unit 160, the memory unit 170, and the communication processor 180 may be included.

The power input unit 105 receives power from the outside and transfers the power to the power detector 110, and the power output unit 150 switches the switch 140 from the controller 130 when the switch 140 is not blocked. The power received via the output is output to an electronic device (not shown) directly connected to an electrical outlet or to an electronic device (not shown) connected through another electric outlet.

When the power input to the power input unit 105 is output to the electronic device through the control unit 130, the switch unit 140 and the power output unit 150, the power detection unit 110 is output to the electronic device Detect active power consumed by. The power detector 110 is not necessarily disposed at the front end of the controller 130, and may be disposed between the controller 130 and the switch unit 140 according to an embodiment, or may be disposed between the switch unit 140 and the power output unit ( It may be arranged between the 150). The power for operating the controller 130 may use power input from the power input unit 105 or may use a separate battery.

The power detector 110 includes a current detector 115 for detecting a load current flowing through the power output unit 150 to an electronic device (not shown), and an electronic device (not shown) through the power output unit 150. The power detector 125 calculates the effective power using the voltage detector 120 and the load current detected by the current detector 115 and the load voltage detected by the voltage detector 120. It includes.

When all the electronic devices connected to the electrical outlet are in the standby state, the power detector 110 detects the standby current flowing to the electronic device through the power output unit 150 and the standby voltage applied to the electronic device, and detects the detected standby current. And the standby voltage may be used to calculate standby power. Subsequently, when it is not known whether the electronic devices connected to the electrical outlet are in a standby state or an operating state (state in which the electronic device is performing a main function), the power detector 110 may output the power output unit 150. The load current flowing through the electronic device and the load voltage applied to the electronic device are detected, and the effective power is calculated using the detected load current and the load voltage. Detection of the active power may be performed under the control of the controller 130 to be described later.

In the power detector 110, the detection of the effective power which should take into account the phase difference between the load current and the load voltage can be performed in various ways. For example, the power detector 110 may be implemented using a Hall element having a multiplication function, or may perform A / D conversion of voltage and current, respectively, to detect active power in a processor, or time-division with current after PWM modulation of voltage. There may be a way to multiply.

The reason for detecting the active power to determine whether the electronic device is in the standby state is that the active power consumed by the electronic device in the operating state is consumed by the electronic device in the standby state due to the phase difference between the load voltage and the load current. This is because the current flowing to the electronic device in the operating state may be smaller than the current flowing to the electronic device in the standby state even if it is larger than the effective power (that is, standby power). Therefore, when it is determined whether the standby state is based only on the load current or the load voltage, an error stage of the power source may be generated because it is incorrectly determined that the electronic device in the operating state is in the standby state.

The controller 130 detects the standby current input to the electronic device and the standby voltage applied to the electronic device when the electronic device (not shown) connected to the electrical outlet is in the standby state, and uses the detected standby current and the standby voltage. The power detector 110 is controlled to detect standby power. In addition, the controller 130 detects and detects a load current input to the electronic device and a load voltage applied to the electronic device when it is not known whether the electronic device (not shown) connected to the electrical outlet is in a standby state. The power detector 110 is controlled to detect active power using the loaded load current and the load voltage.

Then, the controller 130 controls the power applied to the electronic device if the detected effective power when the electronic device is in the standby state is less than or equal to the detected standby power when the electronic device is in the standby state. The switch unit 140 is controlled to block. Therefore, when all of the electronic devices connected to the electrical outlet are folded into the standby state, the switch unit 140 may be cut under the control of the controller 130 to cut off the power supply to the electronic devices. Thereby, unnecessary power consumption of the electronic devices in the standby state can be prevented.

On the other hand, when the effective power detected when the electronic device is in the standby state is greater than the standby power detected when the electronic device is in the standby state, the controller 130 continues the power applied to the electronic device. The switch unit 140 is controlled to maintain.

The switch unit 140 supplies or cuts off power to one or more electronic devices connected to an electrical outlet under the control of the controller 130. Even when the power supply to the electronic device is cut off by the switch unit 140, the control unit 130 to re-power the electronic device or to operate the electronic device at the request of the user later. In addition, a separate battery or the like may be supplied to the user interface 160 and the communication processor 180, or may supply some power input to the power input unit 105.

The user interface 160 receives a user input necessary information for setting standby power directly, receives a learning request of standby power requesting to detect standby power consumed by an electronic device in a standby state, or cuts off a power. A module for receiving a power resupply signal for supplying power to an electronic device in the electronic device, or for receiving an operation signal for operating an electronic device in a power-off state.

The user interface unit 160 includes an infrared transmission / reception module for transmitting and receiving an infrared signal by a remote controller, a button module for receiving signals by a pressing operation, or a touch screen module for receiving signals by a screen touch. Can be. In addition, the user interface unit 160 transmits the above-described standby power setting information, standby power learning request, power resupply request, or electronic device operation signal to the controller 130 according to the received infrared signal, button input, or touch input. I can deliver it. In addition, the user interface unit 160 may transmit an infrared signal to the electronic device for operating the electronic device (that is, for switching the electronic device from the standby state to the operating state).

In addition, the infrared transmission / reception module may be implemented to enable infrared communication using a remote control of an electronic device connected to the power output unit 150 instead of a separate remote control. For example, when a user presses a specific button of the electronic device's remote control or presses an ON signal of the electronic device, the user interface unit 160 controls the power supply resupply request signal or the electronic device operation request signal to the controller 130. Can be delivered to. The user interface 160 may be bidirectional in processing an infrared signal applied to an electrical outlet. First, the user interface unit 160 may receive a remote control signal of an electronic device (eg, a TV), and store the received signal in the memory unit 170 under the control of the controller 130 to learn. . Then, when the controller 130 receives the learned remote control signal, the controller 130 may control the on / off operation of the electrical outlet accordingly.

In addition, the user interface unit 160 may transmit an infrared signal to the electronic device to turn on not only an electrical outlet but also the electronic device by itself using the previously learned remote control signal. To this end, the user interface 160 may include not only an infrared receiving module but also an infrared transmitting module. A user who wants to turn on the electronic device connected to the electrical outlet can turn on the electronic device by pressing a specific button on the remote control once while learning a specific button on the electronic device remote control. When a user presses a remote control button, an infrared signal is received through the infrared receiving module of the user interface unit 160 and thus power is supplied to the electronic device (ie, an electrical outlet is connected). Then, the controller 130 controls the electronic device to transmit an infrared signal for turning on the electronic device through the infrared transmission module of the user interface unit 160. The electronic device that is in the state of being supplied with power from the electrical outlet may receive an infrared signal from the user interface unit 160, and thus may be switched from the standby state to the operating state. In this case, since the power of the electronic device can be turned on by the infrared transmitting module itself, there is an advantage of maximizing user convenience.

The memory unit 170 may store standby power detected according to a standby power or a learning request for standby power set directly by a user, or may store information for recognizing a power resupply signal or an electronic device operation signal.

When the user intends to remotely set standby power using the wireless terminal, the communication processor 180 receives the standby power set by the user through the communication network and transmits the standby power to the controller 130. For example, when the user remotely sets the standby power to 40 Watt, the power supply may be cut off when the active power consumed by the electronic device connected to the electrical outlet drops to 40 Watt or less. In addition, the communication processor 180 may receive a learning request of standby power transmitted by the user using the wireless terminal and transmit the received learning request to the controller 130.

In addition, the communication processor 180 transmits the effective power detected for the electronic device whose status is unknown to the user through the communication network under the control of the controller 130, or the detected active power is lower than the standby power. In this case, it may be processed to transmit information to the user through the communication network indicating that the power applied to the electronic device has been cut off.

Referring to Fig. 4, the electrical distribution board 410 refers to a switch provided for each branch circuit in the branch wiring in the branch wiring from the trunk line to each branch circuit. 4 illustrates an example of a case in which two branch circuits include two branch circuits, and displays a switch in each branch circuit divided into a first electric distribution panel 412 and a second electric distribution panel 414.

Can be placed in. In addition, the standby power saving device 420 is an electronic device (eg, the electric rice cooker 422) continuously supplying power without interrupting the power supplied even when in the standby state and the power supplied when the standby state It may be configured to distinguish the electronic devices (for example, heaters 426 and 430) to block the.
