Since the standby power is blocked by checking the detached state of the contact connecting the power of the device, it has the effect of reliably blocking even the minute current which is difficult to measure the standby power and current value of various home appliances with various used power and standby power. .

However, the multi-tap outlet with the standby power cutoff function exemplified above has a standby power cutoff reference value depending on the number of electric devices connected to the outlet, even though the electric power connected to the outlet is variable and thus the standby power consumption is varied. There is a problem that the standby power is not effectively cut off because it is fixed and not variable.

Republic of Korea Patent Application Publication No. 10-2008-0103193

The present invention has been made to solve the above-described problems, when the electrical device is connected to the power strip outlet, the standby power cutoff reference value is set after the use of additional electrical equipment is connected to the additional use of the electrical device, additionally connected electricity If the power consumed by including the device falls within the allowable range, it provides an intelligent standby power blocking method that automatically sets the standby power blocking reference value.

An intelligent standby power cut-off method of the present invention for achieving the above object is an outlet activation step of supplying power to the power strip is activated outlet; A first detection step of detecting a standby power value of an electric device connected to the power strip and setting a first correction value that is a standby power cutoff reference value; A consumption step of operating the electric device connected to the power strip while the first correction value is set; After the consumption step, if the deviation is within the allowable range through the deviation comparison step and the deviation comparison step in which the power consumption value of the electric device connected to the power tap and the first correction value are compared, the power consumption of the electric device connected to the power tap is standby power. It is determined that it is configured to include a secondary sensing step to set it to the secondary correction value that is the standby power cutoff reference value.

In the first detection step, if the standby power value of the electric device detected by the power tap is less than a preset reference value, the standby power value consumed by the corresponding electric device is set as the first correction value or the standby power of the electric device detected by the power tap. If the value is equal to or greater than the preset reference value, the step may include setting a power value of any one of the preset power ranges as the primary correction value.

After the first sensing step, if the electric device connected to the power tap consumes more than the first comparison reference value, it may be determined as a consumption mode.

After the consumption step, if the electric device connected to the power strip consumes less than the second comparison reference value, the deviation comparison may proceed.

The deviation comparing step may include comparing the allowable range with a value obtained by subtracting the first correction value from the power consumption of the electric device connected to the power strip.

In the outlet activation step, when a plug of an electric device is connected to the power strip, a detection switch provided in the power tap may sense the power supply.

The consumption step may include the step of shutting off the power supplied to the electric device after a predetermined time when the power consumption of the electric device connected to the power tap exceeds a preset over-power cutoff reference value.

When the plug of the electrical device connected to the power strip is disconnected from the power strip, the detection switch provided in the power tap detects this and cuts off the power supplied to the power tap.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

2 is a schematic diagram of a master power strip in the standby power cut-off power strip according to the present invention.

In the standby power cutoff power strip according to the present invention, the master power strip includes a master power input unit 321, a master power cutoff unit 322, and a master power output unit 323. This is input, and supplies power to the electrical equipment connected through the master power output unit 323.

The master power cutoff unit 322 cuts off power supplied to an electrical device connected to the outlet when standby power is generated by the control of the master outlet control unit 310.

In the intelligent standby power cut-off power strip according to the present invention, the master power tap converts AC power input through the master power input unit 321 into DC power in order to supply power to the internal electronic device.

For this purpose, a master power conversion unit 333 is provided, and the master power conversion unit 333 converts commercially available AC from 110V to 220V into DC 12V, 5V or 3.3V.

The master power converter 333 may be, for example, a switching mode power supply (SMPS), and the detailed description thereof will be omitted since the SMPS is already well known to those skilled in the art.

Meanwhile, in the standby power cutoff power strip according to the present invention, the master power strip further includes a master earth grounding unit 332.

In general, buildings in environments where electric devices such as homes or offices are used are designed to protect the electric devices against lightning, static electricity, and sudden electrical changes around by using grounding.

However, in exceptional circumstances, since the grounding is not properly performed, a risk of electric equipment damage or electric shock may occur, and thus, the master earth grounding unit 332 is further provided to be connected to the ground terminal of the power line, such as lightning, static electricity, and sudden Eruption current caused by electrical change is emitted to the outside through ground.

The master power detector 331 measures the power input through the master power input unit 321 and supplied to the electric device.

The master power detector 331 measures a current by connecting a CT sensor or a hall sensor to one P-line or N-line between the master power input unit 321 and the master power output unit 323 to be supplied to an electric device. Sensing power

The master outlet control unit 310 includes a master cutoff reference value changing unit 311, a master cutoff reference value storing unit 312, a master power cut determining unit 314, and a master counter unit 313.

The master cutoff reference value changing unit 311 is driven by receiving a signal indicating that the number of electrical devices connected by the master plug detachable detecting unit 342 described below is changed, and is currently consumed by the master power detector 331. Outputs a control signal for measuring the standby power, and receives the measured standby power value from the master power detector 331 and sets it as a new standby power cutoff reference value and stores it in the master cutoff reference value storage unit 312.

The master cutoff reference value changing unit 311 may set a standby power cutoff reference value.

The master cutoff reference value storage unit 312 stores the standby power cutoff reference value set by the master cutoff reference value changer 311 and outputs the standby power cutoff reference value stored in the master power cutoff determiner 314. The master power cutoff determiner 314 determines whether the power measured by the master power detector 331 corresponds to a standby power cutoff reference value.

The master counter unit 313 receives a signal indicating that the number of electric devices connected by the master plug detachable detecting unit 342 has changed and is driven for a time corresponding to a counter value previously stored or set by a user.

On the other hand, the master cutoff reference value changing unit 311 checks whether the variation of the number of connected electric devices detected by the master plug detachable detecting unit 342 while the master counter unit 313 is driven is not changed. It may be set to change the standby power cutoff reference value only because it is not desirable to change the standby power cutoff reference value frequently when the electric device is repeatedly detached from the power strip within a short time.

The master status notification unit 353 allows the user to intuitively grasp the state of the master power strip of the standby power cut-off power strip according to the present invention. For example, the master status notification unit 353 may include a lamp and a buzzer of green, blue and red.

Each of the lamps may be lighted, turned off or blinking at a predetermined interval, alone or in combination, depending on the current operating mode of the outlet.

For example, when an electrical device is first connected to an outlet or disconnected after being first disconnected, or when an initial setting of the standby power cutoff reference value is to be reset and reset, there is no information on the previously stored standby power cutoff reference value. Initial standby power cutoff reference value should be set by measuring standby power value of connected electric equipment.

This is called the system initialization mode or standby power measurement mode. In this case, during the initial measurement of standby power in the master power detector 331, the flashing is performed in the order of green-> blue-> red lamp, and the standby power measurement is completed. The green lamp will light continuously.

At this time, the buzzer may generate a sound in a predetermined pattern to inform the user that the standby power measurement is completed.

As another example, whenever the master mode button unit 352 described below is pressed, the operation mode of the master power strip of the standby power cutoff power strip according to the present invention may be changed, and the master power tap may operate in the standby power cutoff standby mode. When the green lamp blinks for a certain time, the green lamp is continuously turned on in the standby power off mode, the blue lamp is turned on in the power supply mode, and the red lamp is turned on for a certain time during system initialization mode. It goes out.

On the other hand, the power supplied to the electric device is measured by the master power detector 331 or more by the standby power or the standby mode, or the master mode button unit 352 is pressed or externally according to the conditions such as the operation of the electric device after the standby power cut-off mode. When the standby power shut-off mode is released by the control command of the controller, the standby power shut-off mode is switched to the power consumption mode, and at this time, the blue lamp is continuously turned on.

In the above, the operation of turning on, off, or flashing green, blue, and red lamps according to the change of state of the outlet has been mainly described. Can be informed both visually and audibly.

Although the negative pattern of the buzzer is not presented as an explicit example in the present invention, it should be noted that it may be variously modified by those skilled in the art and may be easily inferred from the present invention.

The master mode button unit 352 sets the state of the master multi-tap in the intelligent standby power cut-off power strip according to the present invention. The outlet described above is a standby power cut-off standby mode, standby power cut-off mode, power consumption mode or system initialization mode. Or outputs a control signal to operate in the standby power measurement mode.

For example, the master mode button unit 352 may be a switch operated by a toggle method, and the mode of the master power tap is changed in a predetermined order whenever the master mode button unit 352 is pressed.

As an example, as described above, when initially pressed in the standby power measurement mode, the power is switched to the standby power blocking standby mode, and when it is pressed again, the power is switched to the power consumption mode. Transition to measurement mode.

In the above-described system initialization mode is preferably carried out in a specific situation, when the system initialization mode is set by simply pressing the master mode button unit 352 once, for example, for a predetermined time without changing the mode, Only when the pressure is continuously applied for 1 to 2 seconds can the system enter the system initialization mode.

The master external interface unit 351 is for interfacing with an external control device (refer to FIG. 6). The master external interface unit 351 is an external control device in a wired operation with a wireless interface for an external control device operating wirelessly. It may include a wired interface for.

For example, the air interface may be designed as an interface system using a ZigBee protocol or an RF radio (400 MHz or 800 MHz).

Meanwhile, the wired interface may be designed as an interface system using protocols such as RS-232, RS-485, RS-422, USB, and TTL.

Since the design of the wired / wireless interface system is known to those skilled in the art, a detailed description thereof will be omitted.

6 is an external view of the external control device 700 of the standby power cut-off power strip according to the present invention, which can be equally applied to a master power strip or a slave power tap, and by a wired or wireless protocol with an external interface of the master power strip or slave power tap. Send or receive data or control signals.

The external controller 700 includes devices for controlling a master tap or a slave tap, that is, a master or slave status notification unit 720, a master or slave mode button unit 730, and a master or slave external interface unit 740. And a master or slave standby power cutoff setting unit 750 and a master or slave infrared transmission / reception unit 710 and a master multi-tap when the external interface unit 740 of the external control device 700 is connected to the external interface unit of the master power strip. When the external interface of the slave power strip is connected, it operates as the external control device of the slave power strip.

The components provided in the external control device 700 perform the same functions as those of the similarly-named components provided in the master tap or slave taps, and thus, the descriptions of the elements of the master tap or slave taps are referred to, and a detailed description thereof will be omitted. .

On the other hand, the external control device 700 is connected to the master power strip or the slave power tap when connected to the master power strip and slave power tap, or on the other hand, to distinguish which slave power tap is connected to when a plurality of slaves exist The connection setting unit 760 may be further provided.

The connection setting unit 760 may store a predetermined number of codes in advance, establish a communication connection with a target to be communicated, and store a predetermined code in the connection target to prevent confusion with other devices.

For example, if you want to communicate with the master multi-tap, set the code to 0000 and then send it to the master multi-tap and receive the connection accept message from the master multi-tap. Since it is not communicated with, it does not operate as an external control device of the slave power strip.

The master or slave infrared transmitting / receiving unit 710 receives a signal from a TV or a general infrared transmitter (remote control) in the standby power blocking mode, and has a function of releasing the standby power blocking mode. Send it out.

Specifically, in order to supply power to the TV when the power button is pressed by the TV remote control, it is inconvenient to first turn off the standby power blocking mode of the outlet and then turn on the TV by pressing the power button of the TV remote control.

However, the external control device 700 according to the present invention (for example, the remote control) receives the TV power on signal of the TV remote control and retransmits the received signal after a predetermined time by pressing the power on button of the TV remote control or standby power of the outlet. Even if you do not press the power turn on button of the TV remote control after canceling the shut-off mode separately, it is possible to turn off the power turn on button of the TV remote control by retransmitting it through the infrared transmitter / receiving unit of the remote control according to the present invention. The result is the same as pressing once.

3 is a block diagram of a slave power strip in an intelligent standby power cut-off power strip according to the present invention.

The configuration of the slave power strip and the operation of each configuration of FIG. 3 are the same as those of the master power tap, except that the power supplied through the slave power input unit 421 is supplied through the master power output unit 323 of the master power tap, and to the master power tap. There is a difference that the slave ID detection unit 341 is not included and the slave ID setting unit 441 is included instead.

In detail, the slave power strip includes a slave power input unit 421, a slave power cut-off unit 422, and a slave power output unit 423, and also a slave power detector 431, a slave grounding unit 432, and a slave power source. Conversion unit 433, slave status notification unit 453, slave mode button unit 425, slave external interface unit 451, slave plug detachable detection unit 442, slave ID setting unit 441 and slave outlet control unit 410 is included.

The slave concentrator controller 410 further includes a slave cutoff reference value changing unit 411, a slave cutoff reference value storage unit 412, a slave counter unit 413, and a slave power cut determination unit 414.

Hereinafter, a description of the overlapping configuration with the master power strip of FIG. 3 will be omitted, and only the slave ID setting unit 441 that does not overlap with the master power strip will be described.

The slave ID setting unit 441 is connected to the master power strip so that when the slave power tap is connected to the outlet of the master power tap, the master power tap may be checked without checking the slave status notification unit 453. By setting IDs on the slave multi-taps respectively, the master multi-tap detects the state of the slave multi-tap by communicating with the slave status notification unit 453 and the master outlet control unit 410 and displays them on the status notification unit of each outlet of the master multi-tap. Make sure

In addition, when a plurality of slave power taps are connected to the master power tap, the number of electric devices connected to each slave power tap is distinguished from each other so that the master power tap recognizes the mode of one slave power tap. This is to not affect the operation.

4 is a slave ID detecting unit 510 of a master power tap and a slave ID setting unit 521, 531, 541, 551 of a master power tap and a pluggable detecting unit of a master power tap and a slave power tap in the standby power cutoff power tap according to the present invention. A circuit diagram according to an example.

The circuit diagram of FIG. 4 may simultaneously have the functions of a slave ID detector and a plug detachable detector in terms of a master power strip.

That is, when the plug of the electric device is connected to the outlet of the master power strip, the contacts A0 to D0 to which the switches S1 to S4 are connected are connected to the resistors R1 to R4 connected to Block_ID_0 to Block_ID_3 according to ON / OFF of the switches S1 to S4. Detects the voltage and detects that the voltage is detected as the plug is connected, and if the voltage is not detected as the plug is not connected, it calculates the number of resistors for which the voltage is detected. Will be detected.

On the other hand, it is preferable that the resistors R1 to R4 use the same value, since the slave ID detection unit 510 of the master power strip simultaneously functions as the master plug detachable detection unit.

The slave ID detection unit 510 of the master power tap may detect the ID of the slave power tap connected to the outlet, which is possible by interaction with the slave ID setting parts 521, 531, 541, and 551 of the slave power tap. Become.

In detail, the slave ID setting unit 521, 531, 541, and 551 may be configured as the rotary switches 522, 532, 542, and 552. Each time it is rotated by a predetermined angle, the resistance value is increased or decreased step by step so that the step change of the resistance value becomes the ID value of the slave.

When the slave power taps are connected to the outlets of the master power taps when the resistance values are gradually changed using the rotary switches 522, 532, 542, and 552 as described above, the rotary switches 522, 532 connected to the respective outlets. , 542, 552 is pressed and the circuit is connected, R1 to R4 are energized by the switch S1 to S4 pressed and connected in series with a resistor so that the voltage detected at R1 to R4 is the rotary switch 522, 532, 542, It is measured step by step according to the resistance value set in 552.

On the other hand, if a master ID is assigned to the voltage value detected by the slave ID detection unit 510 and stored, the ID can be extracted from the voltage values measured in the R1 to R4 and eventually the slave ID can be known. .

4 illustrates that the slave ID detection unit 510 of the master power tap also functions as a plug detachment detecting unit, but may be separated.

In more detail, in the circuit diagram of FIG. 4, the master power strip may have only the function of the slave ID detection unit 510. In this case, the slave ID setting units 521, 531, 541, and 551 of the slave power tap may include the rotary switch 522. 532, 542, 552 or the resistance is not a variable structure, but as the rotary switch 522, 532, 542, 552 is rotated is a structure in which the contacts connected to the contacts A0 to D0 is changed.

At this time, the rotation angle should be equal to the number of slave power strips detectable in the master power tap.

For example, suppose that the number of slave power strips that can be detected by the master power tap is 4, and IDs 1 to 4 are assigned to the resistors R1 to R4, respectively. In this case, the rotary switches 522, 532, 542, and 552 rotate 90 degrees. You can have a different ID each time.

When the rotary switches 522, 532, 542, and 552 of the slave power tap are rotated 180 degrees in the Socket Block_1, the rotary switches may be connected to the Block_ID_1 line in Block_ID_0 to Block_ID_3, and the rotary switch 522 may be connected. Since the resistance R2 is actually measured when the voltage is applied, the ID of the slave connected to the socket Blcok_1 is given 2, and if the rotary switches 522, 532, 542, and 552 are rotated by 270 degrees, the connected contact is C0. Since the resistance at which the voltage is measured is R3, the ID assigned is 3.

In this case, the master or slave plug detachable detecting units 342 and 442 may be configured as separate circuits. FIG. 5 is a circuit diagram of the master or slave plug detachable detecting unit 610 in the standby power cutoff power strip according to the present invention. One example.

The operation of the circuit of FIG. 5 is the same as the circuit of FIG. 4, and the switches S1 'to S4' included in the plug detachable detection switches 620, 630, 640, and 650 are provided in an outlet, and the plug of the electric device is connected thereto. Pressurized to ON.

When the switch S1 'is pressurized and conductive, the voltage is measured from the resistor R1 included in the plug detachable detecting unit 610, so that the electric device is connected to an outlet provided with the switch S1'.

The master or slave plug detachable detecting unit 610 does not need to distinguish the connected electric devices, and only the number of connected electric devices is considered, and thus the rotary switch included in the slave ID setting unit 521, 531, 541, and 551 may be used. It may be removed.

Hereinafter, the standby power cutoff reference value of the standby power cutoff power strip according to the present invention having the configuration as described above will be changed when the power consumption is within the allowable range of deviation after the electric device connected to the outlet is operated. This will be explained in detail.

Since the method of setting the standby power cutoff reference value is the same according to the number of the electric devices connected in the master and slave power strips, the operation of the device will be described below. Use master or slave if necessary.

7 is a flowchart illustrating a process of intelligently shutting off standby power in the standby power cut-off power strip according to the present invention, and FIG. 8 is an exemplary view illustrating activation and deactivation of the standby power cut-off power strip according to the present invention. It is assumed that one electric device is connected to a power strip so that another electric device can be connected while in use.

First, in a state in which the electric device is not connected to the power strip, power is supplied to the power strip to activate the outlet (S110).

As shown in FIG. 8, the multi-tap may include a limit switch (Limit_SW), which is a detection switch, and when the plug of the electric device is connected to the multi-tap, the limit switch detects this and activates the multi-tap so that the electronic device is inside the multi-tap. Ensure power is supplied to the device.

Subsequently, when the plug of the electric device is connected to the outlet, after a time of about 1 second to 2 seconds is counted (S120), the standby power value of the electric device connected to the power strip is detected, and the primary correction value which is the standby power cutoff reference value. This is set (S130).

Here, a reference value for setting the primary correction value may be given.

For example, if an electrical device having a standby power of less than T watts is connected and detected to a multi-tap using T watts as a reference value, the actual standby power consumption is set as a first correction value, and the electrical device having a standby power of more than T watts to a multi-tap. When connected and sensed, set any of the power values below T watts as the primary calibration value.

For example, if the computer main body and the monitor, which are (T-1) watts to the sum of the standby powers, are connected to the power strip, the (T-1) watts actually consumed is set as the primary correction value because the standby power is less than T watts. .

Subsequently, if the electric device is only connected and not operated in the state in which the primary correction value is set, after the time of about 30 seconds is counted (S150), the standby power is cut off (S160).

For reference, when an electrical device having a T watt or more is connected to the power strip, and any one of the power values less than the T watt is set as the primary correction value, the electrical device such as a fan using a rotary switch is used. Or when two or more electrical devices are initially connected.

Then, the electric device connected to the power strip is operated.

In this case, the multi-tap determines that the connected electric device consumes more power than the primary comparison value based on the primary comparison value (S170).

For example, if the primary comparison value is 2T watts, the computer main body and the monitor are operated to determine that the power consumption mode is consumed when more than 2T watts are consumed.

In the consumption mode, in addition to the electric device connected to the power strip, other electric devices may be connected to consume power.

For example, it may be a case where a printer having a standby power of about half of the reference value is connected to a power strip to operate a printer while using a computer main body and a monitor.

In this way, while the power of the first comparison value or more is consumed, the power strip senses the power consumption of the connected electric device.

On the other hand, in the power consumption mode, when the power consumption of the electric device connected to the power tap exceeds a preset over-power cutoff value, the power supplied to the electric device may be cut off after a predetermined time of about 30 seconds.

Subsequently, when the operation of the electric device is stopped or the intensity is adjusted, the multi-tap detects whether the connected electric device consumes more or less than the second comparison value based on the second comparison value of about 2T watts. .

Subsequently, when the electric device connected to the power strip consumes more than the secondary comparison value, it is determined that the power consumption mode is in progress, not in a standby state. When the electric device connected to the power tap consumes less than the secondary comparison value, Deviation comparison is to proceed (S180).

Deviation comparison is to designate an arbitrary Y watt as the allowable deviation range, and to compare whether the deviation value obtained by subtracting the first correction value from the power consumption value of the electric equipment connected to the power tap after the consumption mode is included in the allowable deviation range. .

If the deviation value exceeds the allowable deviation range in the deviation comparison, it is determined that the standby power is not the standby power is blocked.

On the other hand, when the deviation value is less than the allowable deviation range in the deviation comparison, it is determined that the standby power, and the power consumed by the electrical device connected to the multi-tap at this time is set to the secondary correction value of the standby power cutoff reference value (S190).

Subsequently, after a predetermined time of about 30 seconds has elapsed while the electric device connected to the power strip is not operated, standby power is cut off.

The first comparison value, the second comparison value, and the allowable deviation range may be specified as arbitrary values.

In this way, in the present invention, when the standby power cutoff value is initially set, the power consumption of the electric device connected to the power strip is made, and when another electric device is connected and used, the power consumed by including the additionally connected electric device is arbitrary. If it is within the allowable range of, it is automatically set to the standby power cutoff reference value.

On the other hand, when the plug of the electrical device is disconnected from the power strip in the state that the plug is connected to the power strip, the limit switch detects this to cut off the power supplied to the electronic device inside the power strip so that the power strip.

For reference, another standby power cut-off power strip according to the present invention may be provided with a manual switching button (not shown), and when the manual switching button is turned on to switch to the manual mode, the plug of the electric device to the outlet, the power strip The standby power value of the electrical equipment connected to is detected and the primary compensation value, which is the standby power cutoff reference value, is set manually.

Subsequently, if the power consumption of the electric device in the manual mode is less than or equal to the manually set primary correction value, the standby power of the electric device is cut off after a predetermined time.

The manually set primary correction value is maintained until the manual mode is turned off by releasing the manual mode.
