Description

[0001] The present invention relates to an automatic standby power blocking system,

The existing standby power cut-off device is to cut off the standby power flowing between the outlet and the household appliance when the outlet is electrically connected to the household appliance and the household appliance is turned off. The present invention is configured to block the standby power flowing between the outlet and the appliance when the appliance is turned off by installing a standby power cutoff device between the appliance and the outlet as described above. The present invention relates to a method for allowing a memory to be compatible with various household appliances by attaching a memory to a standby power cut-off device in consideration of the fact that the standby power differs for each appliance.

      A conventional technique related to the present invention is disclosed in Korean Patent Registration No. 10-1100375 (published on Dec. 30, 2011). FIG. 1 is a block diagram of the conventional stand-by power cut-off receptacle and standby power cut-off method. 1, the conventional standby power automatic shut-off receptacle includes a switched-mode power suppler for receiving a commercial AC power from an AC input terminal 1 and converting the AC power into a DC power and supplying the AC power to the controller 9

As the plug 10 is removed and the plug pin 11 is disengaged, the slide bar is returned to its original state by the spring, A current measuring sensor (6) for measuring a current amount of the electric power using apparatus from a plug (10) inserted into the switching unit (3) and a switching unit (3) (6) is less than the minimum current < RTI ID = 0.0 > And a control unit (9) for controlling standby power to the electric device through the triac (7) when it is determined that the electric device is in a standby state within a range exceeding a predetermined range of the electric device The memory 8 for storing the minimum current value and the maximum current value can be additionally configured. In addition, the wired / wireless network unit 12 may be further configured to allow the control unit 9 to transmit the standby power cutoff state information and the power use state information of the outlet to the management system using the network. Wireless network, and can receive information on the power usage state and the standby power state of the electric device using the wired / wireless network unit 12, and can receive the control signal from the management system capable of wired / On / off can also be controlled. The measured minimum current value and the maximum current value can be stored in the internal memory of the control unit 9. When the electric device is connected to the output terminal 2, And is turned on. The SMPS 4 supplies electric power to the control unit 9 when the socket unit is maintained in the on state by the switching unit 3. The control unit 9 receiving the power from the SMPS 4 receives the current value of the electric device connected from the current measurement sensor 6. [ In addition, the controller 9 determines the minimum current value and the maximum current value among the current values, determines the rated capacity of the connected electric apparatus, and determines the standby state by applying a standby current value corresponding to the minimum current value , The control unit 9 determines that the electric device is in a standby state within a range exceeding a certain range of the minimum current value and transmits a signal to interrupt the standby power through the standby triac 7 will be. The control unit 9 receives 0 potential point information from the zero crossing unit 5 and receives the AC AC voltage repeatedly at a certain part ON and a certain part OFF. . In this case, the power consumption by the time when the standby power is off (OFF) can be further reduced. Also, when the power use signal of the electric power using apparatus is transmitted from the output terminal 2 during repeated ON / OFF, the signal is automatically connected in the ON state and the power is restored. In addition, when the other electric devices are connected, the current value of the connected electric device can be confirmed by receiving the minimum current value and the maximum current value measured from the current measuring sensor 6, so that the standby current value is automatically reset You can.
