Description
BACKGROUND OF THE
The power consumed by the appliance while the appliance is turned off is called the standby power. Standby power is used to prepare the appliance for use when the appliance is turned off, but the power plug is plugged in. That is, the electrical product is not substantially used by the user, but power is continuously consumed.
In recent years, efforts have been made to reduce electric power demand in a situation where power demand is soaring and power supply shortage is a problem. According to the International Energy Agency, about 10 to 15% of the average power consumption of OECD member countries is consumed as standby power, and in neighboring Japan, it is reported that about 12% of the annual power consumption is consumed as standby power.
In recent years, the use of various electrical appliances is increasing at a rapid pace, and power plugs of several electrical appliances are connected to a single outlet and multi-tap at home or office.
In the conventional outlet and multi-tap, power is shut off uniformly by the power-off switch for interrupting the standby power. Therefore, there is a problem that the power can not be shut off according to the overload capacity of the electrical product connected to the outlet and the multi-tap.
Further, in the conventional standby power cut-off receptacle and the multi-tap, a current detecting IC or a transformer-type SMPS module is used for detecting the standby power. However, since the cost of these components is high, standby power The spread of the wall outlets and multi-tap is negligible.

In the case of a recently developed computer, since the standby power when the computer is turned off is almost similar to the power consumed when the computer is in the sleep mode, the power consumed in the sleep mode is misinterpreted as standby power, Thereby solving the problem of cutting off the power.

A standby power learning method according to an embodiment of the present invention will be conceptually described.
10 is a conceptual diagram illustrating a standby power learning process of a standby power cut-off receptacle according to an embodiment of the present invention.
As shown in FIG. 10 (a), it is assumed that the usage load of the electric apparatus connected to the standby power cut-off receptacle according to the embodiment of the present invention is 150W and the standby power is 5W. At this time, since the electric device before the first use is a standby power state, 150W is measured when the user turns on the power while the current power (NoW) is being measured at 5W. The 5W measured before is already stored in the standby power value (preW). At this time, the current power (NoW) 150W is larger than the standby power value (preW) 5W, and the constant value (the error correction variable according to the power situation of the application site is 3 as the basic value, (PreW) 5W is stored in the standby power learning value LpreW because the measured current power NoW is larger than the standby power value preW even if the current power NoW is a multiple of the standby power value preW. Since the current power (NoW) continues to be measured at 150 W, the current state is maintained. When the electric power of the electric apparatus is turned off, the current power NoW is measured to be 5 W, which is close to the standby power learning value LpreW, If the current power (NoW) remains in the state after the preset standby power allowable time, the latch relay is turned off to interrupt the standby power.
As shown in FIG. 10 (b), if the usage load of the electric appliance connected to the standby power cut-off receptacle is changed or added (at this time, the used load of the changed electric appliance is 320 W and the standby standby power is 12 W ), Since the device before the first use will be the standby power, the current power (NoW) 12W is being measured, and when the power is turned on, 320W is measured. 12W previously measured is already stored in the standby power value (preW). At this time, the present power (NoW) 320W is larger than the standby power value (preW) 12W and the measured value is larger than a multiple of the constant value The standby
Hereinafter, a method of controlling a standby power cut-off receptacle according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
3 to 9 are flowcharts illustrating a method of controlling a standby power cut-off receptacle according to an embodiment of the present invention.
First, as shown in FIG. 3, the
The
Here, when the AC voltage is inputted, it means that the user uses the standby power cut-off receptacle as the standby power sensing state. If an AC voltage is not input, this means that the user uses the standby power cut-off receptacle as a normally energized state.
The continuous energization refers to a state in which electric power is continuously supplied to the electric apparatus without sensing the standby power of the electric apparatus connected to the stand-by power cut-off receptacle, for example, when the household electric appliance such as a refrigerator is connected .
The system of the standby power cut-off receptacle includes various components (for example, a control unit, a voltage sensing unit, a current sensing unit, etc.) for measuring standby power of an electric device connected to the standby power cut- Means a system which is constituted.
Therefore, if the AC voltage is not input, power is not supplied to the system of the standby power cut-off receptacle, and the
Here, the switching between the normal energization or the standby power sensing is achieved by operating the system switch.
In this way, when the standby power cut-off receptacle is used in the normally-energized state according to the user's selection, the power supplied to the system of the standby power cut-off receptacle, such as a general outlet, is cut off to prevent power consumption at the standby power cut- .
If the AC voltage is inputted, it is determined whether a communication signal is input through the wireless communication unit 20 (S50). If a communication signal is input through the

As shown in FIG. 4, the input signal processing step determines whether a switch input is input through the switch unit (S510). A step of turning on / off the
When the switch input is inputted through the

If learning of the infrared signal has been performed, it is determined whether the received infrared signal is the same as the learned value (S524). If the received infrared signal is different from the learned value, If the received infrared signal and the previously learned learned value are identical to each other, the process moves to the infrared signal processing step S200.
Next, the infrared signal processing step (S200) and the short key processing step (S300) will be described in detail with reference to FIG.
The processing method of the infrared signal processing step (S200) will be described.
As shown in FIG. 5, if the infrared signal received in step S524 is the same as the previously learned learned value, it is determined whether the

6, if the switch input through the
The learning process according to the infrared signal reception becomes an infrared signal learning state when the intermediate key input is sensed. At this time, the
Next, the standby power detection step (S400) will be described in detail with reference to FIG.
7, it is determined whether or not the learning of the standby power has been performed (S410). If the learning of the standby power has been performed, a step of checking the overload of the standby power shutoff tool 10 (S100 ).
If there is no standby power learning value, the standby power detection step is started (S412).
First, the
If there is the standby power value preW, the current power NoW is compared with the standby power value preW in step S418.
If the current power NoW exceeds the standby power value preW, the standby power value preW is compared with the current power NoW by multiplying the standby power value preW by a predetermined value (for example, '5') S420). The predetermined value is a power fluctuation error value obtained by measuring a voltage fluctuation value at an arbitrary value and calculating a power fluctuation value therefrom. Even when the same load is applied to the AC line, the voltage changes and there is a power change. Therefore, it is configured to determine again as a value obtained by multiplying the standby power value preW by a predetermined value corresponding to the power fluctuation error value, thereby automatically preventing the learning error due to the power fluctuation due to the error value to be automatically learned as the standby power learning value . For example, the initial default value can be set to '3'.
If the current power NoW exceeds the value obtained by multiplying the standby power value preW by a constant value, the standby power value preW is stored as the standby power learning value LpreW and the standby power learning is terminated (S424) When the standby power learning value LpreW is stored, the flow goes to step S100 of checking overload of the standby
If the standby power value preW does not exist in step S416, the current power NoW is stored as the standby power value preW in step S430.
If the standby power learning value LperW has not been stored in step S422, the basic setting value is stored in the standby power learning value LpreW (S440).
In step S418, if the current power is equal to or lower than the standby power value, it is determined whether the standby power allowable time has been exceeded (S450).
If the standby power allowable time is exceeded, it is determined whether a computer detection signal is input through the USB communication unit 40 (S452). If the computer detection signal is not input, the standby power detection step is terminated (S454), the
If the computer detection signal has been input in step S452, the process proceeds to step S1.
Next, the step S100 of checking the overload of the stand-by power cut-
As shown in FIG. 8, the current (i) level (S110) of the commercial AC power source and the power factor of the
The standby power learning value LpreW is compared with the current power NoW in step S116. If the standby power learning value LpreW exceeds the current power NoW, it is determined whether or not the standby power allowable time has been exceeded S120).
If the computer detection signal is not detected, the
If the standby power learning value LpreW is less than or equal to the current power NoW, it is determined whether the current power is greater than a preset overload power. If the current power is equal to or less than the overload power, the process moves to step S1.
If the current power exceeds the overload power, it is determined whether the overload time has been exceeded (S910). If the overload time exceeds the overload time, it is determined that the overload is detected (S912) An overload warning sound is output in step S914 and the
However, if it is determined in step S11 that the overload time is not exceeded, it is determined that the overload is temporarily input, and the process proceeds to step S1.
Next, the communication signal processing step S800 will be described.
As shown in FIG. 9, the communication signal processing step S800 determines whether or not status request data of the standby power cut-off receptacle has been received (S810). The reception of the status request data means that when the remote control of the standby power cut-off receptacle is performed via the wireless communication unit, the status information of the standby power cut-off receptacle at the remote controller such as the home network to determine the status of the standby power cut- Lt; / RTI >
Upon receiving the status request data, the status of the standby power cut-off receptacle is transmitted (S812), and it is checked whether the latch relay is turned on (S814). If the latch relay is turned on, And if the latch relay is off, the process moves to step S1.
If the status request data is not received in step S810, it is determined whether the latch relay control data is received through the wireless communication unit (step S820). It is determined whether the latch relay control data is data for turning on the latch relay in step S822. If it is the latch relay on data, the latch relay is turned on in step S824 and the standby power detection step S400 is performed.
If it is not the latch relay on data (that is, the latch relay off data) in step S822, the latch relay is turned off (S826), and the process moves to step S1.
As described above, according to the control method of the standby power cut-off receptacle according to the embodiment of the present invention, by comparing the current power and the standby power learning value of the electric device connected to the standby power cut- , It is possible to accurately measure the electric power consumed in the electric device. Therefore, even if the electric appliance connected to the standby power cut-off
In addition, the on / off state of the power of the computer can be grasped through the
In addition, it can improve the competitiveness of the product by using the shunt resistor circuit so that the circuit for detecting the standby power can be potatoed in the optimal state, and the standby power and the maximum rating of the receptacle to be used are smoothly Can be detected.
In addition, even if the electric device is changed during use, it is not necessary to separately set the standby power, and it is blocked by the purge function, thereby maximizing the convenience and safety of the user.
In addition, when used above the maximum rating, the product can be protected against fire and safety through the overload shutoff function.
In addition, by configuring the normal energization mode and the standby power cut-off mode, it is possible to maximize the usability of the user and to prevent the electric safety accident by the contact of the normal changeover switch for the maximum rated use of the outlet for constant energization , A protection circuit is constructed, and unnecessary power consumption is zeroed by using a latch relay, thereby realizing energy saving.
