The controller 22 sets the power application condition to the electronic products connected to each sphere according to the sensing mode set by the main device 10. That is, when the sensing mode is the human body detection, when the human body sensor detects the human body, power is applied to each sphere. When the sensing mode is the infrared remote control signal detection, the infrared sensor detects the infrared remote control signal to apply power to each sphere. When the sensing mode is the RF signal detection, when the RF receiving sensor detects a high frequency (RF) signal, power is applied to each sphere. If there is no sensing mode, power is applied to each sphere when the drive switch 26 is operated.

In addition, the controller 22 sets a power application condition to the electronic device connected to each sphere according to the driving mode set from the main device 10. If the driving mode is general, power is always applied to each sphere. If the driving mode is power saving, it is determined whether the electronic devices connected to each sphere are individually in the standby mode, and if only the electronic products are in the standby mode, only the power applied to the sphere is cut off.

The current sensing unit 28 may measure power consumption for a predetermined period, obtain the average value, and set the average value to standby power consumption and power consumption of the electronic product.

The operation of the power saving type outlet device according to the present invention configured as described above will be described.

First, the assertion value sets the sensing mode, driving mode, and standby mode determination reference values of a plurality of multi-tap devices.

The main device 10 sets the sensing mode of the plurality of multi-tap devices 20 by receiving the sensing mode (human body detection / infrared remote control signal detection / RF signal detection / no signal) directly from the user through the input / output unit 13. There is a method of setting and a method of setting an optimal sensing mode according to the type of the electronic product by receiving the type of the electronic product connected to the corresponding tap device 20 from the user through the input / output unit 13.

In addition, the method of setting the drive mode of the plurality of multi-tap devices 20 by the main device 10 includes a method of directly receiving and setting a drive mode (normal / power saving / interlocking) from the user through the input / output unit 13, and There is a method of selecting the type of electronic device connected to the multi-tap device 20 from the user through the unit 13 and setting an optimal driving mode according to the type of the electronic device.

For example, in the home theater system, the sensing mode is set to infrared remote control signal sensing or RF signal sensing and the driving mode is set to interlock. Then, when the user operates the power button of the television remote control, the multi-tap device 20 senses and drives the infrared remote control signal or the RF signal, and power is supplied to the home theater system including the television. On the other hand, when the TV is turned off and the TV is in standby mode, the power supply to the television and other peripherals is cut off.

In the case of a computer system, the sensing mode is set to none and the driving mode is set to interlocked. Then, when the user operates the drive switch, the computer system supplies power to the computer main body, and when the computer main body is turned off to the standby mode, the computer system cuts off all power supplied to the computer main body and all the computer peripherals.

In the case of the refrigerator, the sensing mode is set to none and the driving mode is set to general so that the refrigerator is constantly supplied with power.

In the case of a washing machine, a microwave oven, or an air conditioner, the sensing mode is set to detect a human body and the driving mode is set to power saving, so that power is supplied to the electronic product when a person approaches the electronic product.

Next, the claim value obtains standby power consumption information of the electronic device connected to each sphere of the corresponding power strip device 20, and requests power consumption information to each power strip device 20. Then, the current sensing unit 28 of the multi-tap device 20 measures the power consumption of the electronic products connected to each sphere. At this time, since the main device 10 and the power strip device 20 do not know whether the electronic device is in the standby mode, the user guides the user to maintain the standby mode.

When the standby power consumption information is received from the multi-tap device 20, the main device 10 sets the standby mode determination reference value using the standby power consumption received from the multi-tap device 20. However, when the standby power consumption is measured to set the standby mode determination reference value, if the corresponding electronic product is not in the standby mode, the measured standby power consumption may be high or low. If the measured standby power consumption is higher than the upper threshold value or lower than the lower threshold value, an error occurs and the standby power consumption of the electronic product is measured again.

The asserted value stores the standby mode determination reference value for each sensing mode, driving mode, and distinction for each multi-tap device, and delivers it to the corresponding multi-tap device.

The multi-tap device 20 receives the sensing mode, the driving mode, and the discrimination standby mode determination reference values set by the user from the main device 10, and stores them in the storage unit 25, according to the sensing mode and the driving mode. Apply power to or disconnect power from connected electronics.

If there is no sensing mode and the driving mode is normal, the power strip device is driven in the same manner as the general power strip device, and power is continuously supplied to all the spheres of the power strip device.

In the absence of the sensing mode, power is supplied to all the spheres of the multi-tap device only when the user operates the drive switch. In this case, when the driving mode is power saving, each sphere of the power strip device is independently determined to determine the standby mode, and power is applied or cut off. When the driving mode is linked, whether the electronic device connected to the master port of the power strip device is in standby mode or not. In this case, the power of all the spheres of the multi-tap device is turned on or off.

When the sensing mode is set to infrared remote control signal detection or RF signal detection, the control unit 22 of the multi-tap device 20 receives the infrared signal or RF signal by the infrared detection sensor or the RF reception sensor human detection sensor of the sensor unit 23. Detect if When the infrared signal or the RF signal is received, the switching controller 27 is operated to apply power to the master sphere 29 and the slave sphere 30. When the infrared signal or the RF signal is not received, the switching control unit 27 is operated to cut off power to the master sphere 29 and the slave sphere 30.

When the infrared signal or the RF signal is received, the driving is performed differently according to the driving mode (power saving / interlocking) set by the user.

When an infrared signal or an RF signal is received, power is applied to both the master sphere 29 and the slave sphere 30. Then, for example, the user can turn on and drive the television connected to the master sphere 29 and the DVD device connected to the slave sphere 30 to watch a DVD movie. While watching a movie, the power consumed by the electronic product increases, and the controller 22 may recognize that the electronic product is in a driving state from the power consumption information of the electronic product measured by the current sensing unit 28.

After watching a movie, when the user turns off the television, the television enters the standby mode. Then, the power consumed by the television becomes standby power consumption, that is, a standby mode determination reference value. The controller 22 determines that the television is in standby mode, and operates the switching controller 27 to operate the master sphere 29 and the slave sphere 30. Shut off all power supplied to the unit. In other words, the user only turns off the television, but the standby power of both the television and the DVD device is cut off.

When the driving mode is power saving, the controller 22 determines whether the electronic device connected to the master sphere 29 and the slave sphere 30 is in standby mode, respectively, and cuts off only the power of the sphere in standby mode. That is, when the electronic device connected to the master sphere 29 is in a driving state and the electronic device connected to the slave sphere 30 is in the standby mode, power is applied to the master sphere 29 and the slave sphere 30 cuts off the power. .
