Hereinafter, an outlet device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the outlet device of this example includes a user input unit 10, a storage unit 20, an operation control unit 30 connected to the user input unit 10 and the storage unit 20, and an operation control unit 30.

The user input unit 10 is for inputting commands or data necessary for an operation according to a user's operation, and generates a signal corresponding to the user's input operation and applies it to the operation control unit 30 .

Accordingly, the operation controller 30 reads the signal applied from the user input unit 10 to determine an input command or data.

Using the user input unit 10, the user may input the operation mode and allowable amount of electricity consumed by each outlet 51 to 53.

1, one user input unit 10 is provided to adjust operating conditions of each outlet 51-53, but, unlike this, a separate user input unit 10 may be provided for each outlet 51-53. .

The user input unit 10 may include a button-type switch whose state changes according to a selection operation, a touch screen, and the like.

In addition, the user input unit 10 may include a power supply switch (not shown) for each outlet 51-53, and the user manually turns on each power supply switch to the corresponding outlet 51-53. ) can be manually controlled.

The storage unit 20 is a storage medium in which data necessary for the operation of the current consumption control device and data generated during operation are stored, and may be a memory or a hard disk.

Accordingly, the operation control unit 30 may store operation state information of each outlet 51 to 53 determined using a signal applied from the user input unit 10 .

At this time, the operation state information of each outlet 51 to 53 may include an operation mode and allowable amount of electricity consumption of each outlet 51 to 53 input through the user input unit 10 .

An operation mode of the outlets 51 to 53 that can be set by the user may be one of a manual mode, a constant mode, and a power cut mode.

The manual mode is a mode in which it is possible to select whether or not to supply power to corresponding outlets 51 to 53 according to a user's selection operation.

The constant mode is a mode in which power is always supplied to corresponding outlets 51 to 53 regardless of a user's operation.

In addition, the power-off mode is a mode in which power supply is completely cut off, and power supply to the corresponding outlets 51-53 is completely cut off to cut off electricity to the corresponding outlets 51-53.

The amount of electricity consumed may be at least one of current consumption and power consumption, and the allowable amount of electricity consumption may be at least one of allowable current consumption and allowable total power consumption.

The total amount of power consumption may be the total amount of power consumed during a predetermined period (eg, 30 days), that is, the accumulated amount of power, and the allowable total amount of power consumption may be the total amount of accumulated power determined by the user.

The operation control unit 30 is a control unit that controls the overall operation of the outlet device and performs calculations, and may be, for example, a central control unit (CPU) or a main control unit (MCU) made of a semiconductor chip. .

Accordingly, the operation of the outlet device can be controlled by the operation control unit 30 .

The communication unit 40 is for communication with an external device such as a user terminal 70 such as a smart phone, and may perform at least one of wired communication and wireless communication.

The communication unit 40 may include an Internet communication module and a short-distance communication module such as Wi-Fi, zigbee, or blue-tooth.

Therefore, the user can receive operation state data generated through the operation of the operation controller 30 using the user terminal 70, and also use the user terminal 70 instead of the user input unit 10 to receptacle devices. It is possible to perform input operations such as control commands or necessary data to control the operation of.

At least one of the operation mode setting signal of each outlet 51-53 and the allowable electricity consumption setting signal of each outlet 51-53 is transmitted from the user terminal 70 by the user's operation using the user terminal 70. Then, the operation control unit 30 receives the operation mode setting signal and the allowable electricity consumption setting signal transmitted through the communication unit 40, and according to the received setting signal, the operation mode of each outlet 51-53, the allowable current ( That is, the allowable load amount) and the amount of electricity consumed can be set.

Each of the outlets 51 to 53 is connected to the electric/electronic product 100 that operates using electricity, and serves to supply power transmitted from the power supply line L1 to the connected electrical/electronic product 100 .

In this example, the number of outlets provided in the outlet device is shown as three, but is not limited thereto and may be one or four or more.

As shown in FIG. 1, each outlet 51-53 has a plug insertion opening 511-531 into which a plug of the electric/electronic product 100 is inserted, and a plug insertion detecting unit connected to each plug insertion opening 511-531. (512-532), a switching unit (eg, relay) connected to the power supply line (L1) and the plug insertion port (511-531) (513-533), connected to the input terminal of the plug insertion port (511-531) A current sensor 514-534 and a voltage sensor 515-535 connected to each switching unit 513-533 may be provided. As described above, each plug insertion hole 511-531 is It is connected to the power supply line L1 through the corresponding switching unit 513 to 533 and can supply power applied from the power supply line L1 to the electrical and electronic product 100 inserted therein.

Each plug insertion detecting unit 512-532 detects whether or not the plug of the electronic product 100 is inserted into the corresponding plug insertion hole 511-531, and transmits detection signals A1-A3 of the corresponding state to the operation controller 30 ) can be output. At this time, each plug insertion detector 512 to 532 may transmit unique identification information of the outlet 51 to 53 to which it belongs through detection signals A1 to A3.

Accordingly, each plug insertion detection unit 512-532 is installed in the corresponding outlet 51-53 to correspond to the corresponding plug insertion hole 511-531.

Each plug insertion detection unit 512-532 has two output terminals (e.g., OUT1 and OUT2) whose state changes depending on whether or not the electrical/electronic product 100 is inserted, for example, and the value of the output signal changes. can do.

Therefore, when the electrical/electronic product 100 is inserted into the corresponding plug insertion hole 511-531, the state of the plug insertion detection unit 512-532 is changed by the insertion operation of the electrical/electronic product 100, and output from each output terminal The state of the signal changes and the detection signals A1-A3 of the corresponding state [eg, OUT1 = 1', OUT2 = '0' (first state)] are sent to the operation control unit 30 through the output terminals OUT1 and OUT2. can be printed out.

Conversely, when the plug of the electric/electronic product 100 inserted into the plug insertion part 511-531 is pulled out of the plug insertion hole 511-531, the state of the corresponding plug insertion detection part 512-532 changes to the initial state, The operation control unit 30 transmits the detection signals A1-A3 in a state different from the first state (eg, OUT1 = '0', OUT2 = '1' (second state)) through the output terminals OUT1 and OUT2. can be output as

For this reason, the operation control unit 30 uses the state of the detection signals A1-A3 input from each plug insertion detecting unit 512-532 to place the electrical/electronic product 100 in the corresponding plug insertion port 511-531. It can determine whether a plug is inserted.

Each of the switching units 513 to 533 may be located between the operation control unit 30 and the corresponding plug insertion hole 511 to 531 .

Each switching unit (513-533) changes its operating state according to the control signal of the operation control unit 30 and supplies power (that is, power applied through the power supply line (L1)) to each corresponding plug insertion hole (511-531). can control.

The switching unit 513-533 has one terminal connected to the operation control unit 30 and one terminal connected to a coil and a power supply line L1, the other terminal of which is grounded, and a corresponding plug insertion hole 511-531 It may be provided with two switches, the other terminals of which are connected to each other.

Accordingly, the coils of the respective switching units 513 to 533 may be magnetized or the magnetization state may be released according to the control signal applied from the operation control unit 30 .

The two switches are turned on when the coil maintains a magnetization state, and by the on state of these switches (ie, the operating state of the switching unit), the power supply line L1 is electrically connected to the plug insertion holes 511-531, and power Power of the supply line L1 may be supplied to the corresponding plug insertion holes 511-531 through the corresponding switching units 513-533.

On the other hand, when the magnetization state of the coil is released, the two switches are turned off, and the electrical connection between the power supply line L1 and the plug insertion holes 511 to 531 is cut off. Due to this, the power applied from the power supply line L1 is supplied to the plug insertion hole 511-531 by the corresponding switching unit 513-533 in an off state (eg, a disconnected state in an inactive state). will not be able to

Each current sensing unit 514-534 may be positioned between each switching unit 513-533 and the plug insertion opening 511-531, and the magnitude of the current applied to the corresponding plug insertion opening 511-531, that is, the corresponding The amount of current consumed in the outlets 51 to 53 may be detected, and signals B1 to B3 corresponding to the size of the sensed current may be output to the operation control unit 30 .

For this reason, the operation control unit 30 can measure the amount of current consumed in each outlet 51-53 using the current detection signals B1-B3 applied from each current detection unit 514-534. have.

In FIG. 1, the current sensing unit 514-534 is located between the corresponding switching unit 513-533 and the plug insertion hole 511-531 and is located behind the corresponding switching unit 513-533. It may be located in front of the parts 513-533. In this case, each current sensing unit (514-534) is located between the power supply line (L1) and the corresponding switching unit (513-533), and according to the operation state of the corresponding switching (513-533), the corresponding plug insertion hole (511-534) 531), consumption current (ie, load) may be sensed according to whether the electrical/electronic product 100 is operating.

Therefore, the operation control unit 30 uses the current sensing signals B1 to B3 applied from the current sensing units 514 to 534 to determine the amount of current consumed in each plug insertion port 511 to 531 (that is, the size of the load). amount) can be measured.

Each voltage detector (515-535) is connected to each outlet (51-53) and detects the magnitude of the voltage applied to the plug insertion hole (511-531) to detect a voltage detection signal (C1) corresponding to the magnitude of the detected voltage. -C3) can be output to the operation controller 30.

Accordingly, the operation control unit 30 may measure the magnitude of the voltage applied to the respective outlets 51 to 53 using the voltage detection signals C1 to C3 applied from the voltage detection units 515 to 535.

Each of the detection signals B1-B3 and C1-C3 output from the current detection unit 514-534 and the voltage detection unit 515-535 may include unique identification information of the corresponding outlet 51-53.

Therefore, the current consumption and voltage of each outlet 51-53 determined by the detection signals B1-B3 and C1-C3 of the current detection unit 514-534 and the voltage detection unit 514-534 Using this, the operation control unit 30 can calculate the amount of power consumed by each outlet 51 to 53.

Next, referring to FIGS. 2A and 2B , the operation of the outlet device of this example having this structure will be described.

First, when power required for operation of the outlet device is supplied, the operation of the operation controller 30 may be started (S10).

Accordingly, the operation control unit 30 first detects plug insertion detection signals A1-A3 applied from the corresponding plug insertion detection units 512-532 of each plug 51-53 to each outlet 51-53. It is possible to determine whether the electrical and electronic product 100 is inserted (S11).

Accordingly, the operation control unit 30 determines whether the electrical/electronic product 100 is not inserted into the corresponding plug insertion hole 511-531 by the plug insertion detection signals A1-A3 applied from the plug insertion detection units 512-532. It is possible to determine whether there is a plug that does not exist.

If there is a plug (eg, the first plug) 51 into the plug insertion holes 511 to 531, into which the electrical and electronic product 100 is not inserted (S12), the operation control unit 30 determines the operation mode of the corresponding outlet 51. Regardless of this, the power supply to the corresponding plug 51 can be cut off (S13).

However, when it is determined that the outlet into which the electrical/electronic product 100 is currently inserted exists by the plug insertion detection signals A1 to A3 applied from the plug insertion detection units 512 to 532 (S14), the operation control unit (30) is the operation of the corresponding outlet inserted into the electrical and electronic product 100 (hereinafter, the outlet 51-53 inserted into the electrical and electronic product 100 is referred to as a 'control target outlet') 51-53. The operation of the corresponding consoles 51 to 53 can be controlled according to the determined operation mode by determining the mode (S14).

Accordingly, the operation control unit 30 may determine the operation mode of the control target outlet using the data stored in the storage unit 20 .

In the storage unit 20, the operation mode of each outlet 51 to 53 is already determined.

As described above, the operation mode of the outlets 51 to 53 may be determined according to the operation of the operation control unit 30 by a mode setting signal applied through the user input unit 10 or the communication unit 40.

For example, the operation controller 30 may determine whether a mode setting signal is input through the user input unit 10 or the communication unit 40 .

Therefore, when a mode setting signal for the corresponding outlet 51-53 is input through the user input unit 10 or the communication unit 40 according to the user's operation, the operation control unit 51-53 transmits the signal together with the mode setting signal. It is possible to determine the outlets 51 to 53 whose operation mode is to be set or changed using the outlet identification code.

Then, the operation controller 30 determines the operation mode selected by the user using the corresponding mode setting signal.

Next, the operation control unit 30 converts the current operation mode of the corresponding outlet stored in the storage unit 20, that is, the outlet corresponding to the outlet identification code, into the determined operation mode, that is, the operation mode corresponding to the input mode setting signal. can be changed

Therefore, the user can change the desired operation mode of the outlets 51 to 53 using the user input unit 10 or the user terminal 70 whenever desired, and the operation control unit 30 stores the data in the storage unit 20. The operation of the corresponding outlets 51-53 can be controlled according to the stored operation mode of each outlet 51-53.

As described above, the operation mode of the outlets 51 to 53 settable by the user may be one of a manual mode, a constant mode, and a power cut mode.

Next, assuming that the first outlet 51 among the plurality of outlets 51 to 53 is the outlet to be controlled, the operation of the outlet to be controlled according to each operation mode will be described.

First, when the operation mode of the outlet 51 determined by the user is the manual mode (S15), the operation control unit 30 performs a corresponding switching operation according to the operation state of a power supply switch (not shown) provided in the user input unit 10. By controlling the operation of the unit (eg, the first switching unit) 513, it is possible to determine whether or not to supply power to the corresponding first outlet 51, that is, the first plug insertion hole 511 (S16).

That is, when the power supply switch is turned on by the user and an on signal corresponding to the on operation of the power supply switch is input to the operation control unit 30 (S16), the operation control unit 30 connects the first outlet 51 A driving signal is output to the coil of the first switching unit 513 to magnetize the corresponding coil. Due to the magnetization of the coil, the switch of the first switching unit 513 is turned on and the first switching unit 513 changes from a non-operating state to an operating state to electrically connect the power supply line L1 and the first outlet 51. Connect (S16).

Therefore, the power applied from the power supply line L1 is supplied to the corresponding plug insertion hole 511 through the current sensing unit 514 through the turned-on switch of the first switching unit 513 in an operating state, so that the first outlet 51 becomes an active state where power is supplied.

However, when the user maintains the power supply switch in an off state and the corresponding off signal is input to the operation control unit 30, the operation control unit 30 does not output a driving signal to the coil of the first switching unit 513 and the coil does not It becomes a non-magnified state (S18).

Accordingly, the switch of the first switching unit 513 is turned off and the first outlet 51 is electrically separated from the power supply line L1. Due to this, the power supplied from the power supply line L1 cannot be applied to the plug insertion hole 511 of the first outlet 51, and the first outlet 51 is in an inactive state in which no power is supplied.

However, when the first outlet 51 is set to the regular mode by the user (S19), the operation control unit 30 outputs a driving signal to the coil of the first switching unit 513 to the first plug insertion port 511. Power is supplied, and thus, in the case of the regular mode, the corresponding outlet 51 becomes active regardless of the off operation of the power supply switch (S110).

However, when the operation mode of the corresponding outlet 51 is not the manual mode and the normal mode, the operation controller 30 determines the operation mode of the corresponding outlet 51 as the power cut mode.

Therefore, when the first outlet 51 is determined to be in the power cut mode by the user, the operation control unit 30 stops the output of the driving signal to the first switching unit 513 to put the first switching unit 513 in an inoperative state. By controlling to, it is possible to control the first outlet 51 in an inactive state (S111). Accordingly, in the power cut mode, the corresponding outlet 51 becomes inactive regardless of the on operation of the power supply switch.

In this example, the order of determining whether the plugs 51 to 53 of the electrical/electronic product 100 are inserted and the order of determining the operation mode of each outlet 51 to 53 may be changed. .

In addition, the user may set the permissible amount of electricity consumed by each outlet 51 to 53 using the user input unit 10 or the user terminal 70 .

In this case, the allowable amount of electricity consumption (eg, the allowable amount of current consumption or the allowable total amount of power consumption) for the plurality of outlets 51 to 53 may be the same as or different from each other.

The permissible amount of electricity consumed for each of these outlets 51 to 53 may be determined according to the amount of electricity consumed (eg, the amount of power consumed) of electrical and electronic products connected to the corresponding outlets 51 to 53 .

The allowable amount of electricity consumed for each outlet 51 to 53 can also be done through the user terminal 70 through the user input unit 10 or the communication unit 40 in the same way as the operation mode selection operation, and the operation control unit 30 controls the user Allowable electricity consumption for each outlet 51 to 53 may be determined using a signal input through the input unit 10 or the communication unit 40 and stored in the storage unit 20 .

Accordingly, the operation control unit 30 may store in the storage unit 20 the type of operation mode and allowable amount of electricity consumption, which are operation state information for the first to third outlets 51 to 53 .

Therefore, when the operation mode of the control target outlet 51 is the manual mode, when the power supply switch is turned on by the user, the switching unit 513 of the control target outlet 51 is operated, and the power supply line L1 is connected to the corresponding plug insertion hole ( 511) or when power is supplied from the corresponding power supply line L1 to the corresponding plug insertion hole 511 as a regular mode, the operation controller 30 controls the corresponding current detector 514 of the outlet 51 to be controlled. ) and the current detection signal B1 and the voltage detection signal C1 output from the voltage detection unit 515, it is possible to determine the operating state of the corresponding outlet 51.

Therefore, the operation control unit 30 uses each current detection signal B1 output from the first current detection unit 514 and the voltage detection signal C1 output from the first voltage detection unit 515 to control the outlet to be controlled. Current consumption current and current voltage consumed in (51) can be measured (S112, S113).

In addition, the operation control unit 30 may measure the current power consumption using the current consumption current and the current voltage, calculate the total amount of power consumption, which is the total amount of electricity consumption, and store it in the storage unit 20 (S114).

Therefore, the operation control unit 30 determines the size of the current consumption of the control target outlet 51 to which power is currently supplied using the current detection signal B1 applied from the current detection unit 514, and determines the size of the current consumption. The size of the current consumption current can be compared with the size of the allowable current consumption stored in the storage unit 20 (S115).

When the current consumption of the control target outlet 51 is greater than the allowable current consumption (S115), the operation controller 30 transmits a driving signal applied to the first switching unit 513 of the control target outlet 51. By blocking the first switching unit 513 to an inoperative state, power applied to the first outlet 51 may be cut off (S116).

Accordingly, power supply to the electric/electronic product 100 or the movable outlet connected to the controlled outlet 51 is cut off.

As such, if the current consumption current consumed by the control target outlet 51 exceeds the allowable current consumption, the power applied to the control target outlet 51 is automatically cut off according to the control operation of the operation controller 30. Therefore, only current consumption that is equal to or less than the allowable current consumption set for the corresponding outlet 51 can be achieved.

Accordingly, the risk of fire or excessive current consumption due to overload in each of the outlets 51 to 53 is prevented.

In addition, if the current total power consumption (ie, the current total consumption) of the control target outlet 51 exceeds the allowable total power consumption (ie, the allowable total electricity consumption), the operation control unit 30 switches the corresponding switching unit 513 It is possible to cut off the power applied to the outlet 51 by controlling the inactive state (S117, S118).

Therefore, even if the operation mode of the control target outlet 51 is a state in which power is currently supplied by the manual mode or the regular mode, the control object outlet ( Power supply to 51) can be controlled.

In an alternative example, the receptacles 51-53 may omit the current detectors 514-534 and voltage detectors 515-535, in which case the operation control unit 30 determines whether or not the plug is inserted and operates. The operation of each outlet 51 to 53 can be controlled using only the mode.

In another alternative example, the outlets 51-53 may omit the voltage detectors 515-535, and in this case, the operation control unit 30 uses only whether the plug is detected, the operation mode, and the allowable current consumption. Thus, the operation of each outlet 51 to 53 can be controlled.

In another alternative example, when the operation mode of the outlets 51 to 53 is the constant mode, the power supply cut-off control of the corresponding outlet is performed using only one of current consumption current and total power consumption, or current consumption current and total power consumption. Regardless of the amount of power, power can be supplied at all times while the plug of the electric/electronic product is inserted into the plug insertion hole of the corresponding outlet.

The operation of the outlet device of this example can be summarized as follows.

At least one of a case where the electrical/electronic product 100 is detected as being inserted into the corresponding plug 51-53 prior to using the electrical/electronic product 100 and a case where the electrical/electronic product 410 is in use after the plug is inserted , if the accumulated power exceeds the allowable total power consumption set by the operation of the user input unit 10, etc., the power delivered to the corresponding outlets 51-53 is automatically cut off, and the communication unit 40 if necessary. ), the current state may be notified to the corresponding terminal (eg, the user terminal 70) of the user, guardian, or administrator through a text message or the like.

To this end, the plug of the electric/electronic product 100 is inserted into the plug insertion hole 511-531 of the corresponding outlet 51-53, and a request for power supply to the corresponding outlet 51-53 is made in a manual mode from the outside. When this is done (ie, the power supply switch is turned on), the operation control unit 30 drives the switching unit 513-533 of the corresponding outlet 51-53 to supply power to the corresponding outlet 51-53. can do.

Then, the operation control unit 30 calculates the current cumulative power consumption consumed in the corresponding outlet unit 51-53 using the current sensor 514-534 and the voltage sensor 515-535, and calculates When it is determined that the accumulated power consumption exceeds the set value of the allowable total power consumption, the operation control unit 30 controls the operation of the corresponding switching unit 513-533 to supply power to the corresponding outlet 51-53. can block

In addition, the operation control unit 30 uses the communication unit 40 to transmit text messages to the corresponding terminal (eg, 70) of the user, manager, or guardian, so that the current state, that is, the current accumulated power consumption exceeds the allowable total power consumption. The user, administrator or guardian can be notified of the status.

In addition, the operation control unit 30 may determine whether or not to supply power to the corresponding outlets 51 to 53 using current consumption (ie, consumption load).

For example, at least one of a case where the electric/electronic product 100 is inserted into the plug insertion hole 511-531 and a case where the electrical/electronic product 100 inserted into the plug insertion hole 511-531 is being used. , if the current consumption (i.e., current load) exceeds the allowable current consumption of the corresponding outlet (51-53), the power supply to the corresponding outlet (51053) is cut off and, if necessary, the terminal of the user, administrator or guardian The current state may be notified by text or the like.

To this end, when the operation mode of the corresponding outlet (51-53) is a manual mode or a normal mode, when the plug of the electric/electronic product 100 is inserted into the plug insertion portion (511-531), the plug insertion detection unit (512-531) 532 detects this and transmits the corresponding signal to the operation control unit 30, whereby the operation control unit 30 drives the switching units 513-533 of the corresponding outlets 51-63 to operate the corresponding outlets 51-63. 53) can be supplied with power.

Then, the operation control unit 30 calculates the current consumption amount consumed in the corresponding outlets 51-53 using the current detection units 514-534, and the calculated current consumption exceeds the set value of the allowable current consumption. When determined to be in one state, the operation control unit 30 may control the operation of the corresponding switching unit to cut off power supply to the corresponding outlet.

In addition, the operation control unit 30 may use the communication unit 40 to transmit a text message to the terminal of the user, manager, or guardian to notify the current state, that is, a state in which the current consumption exceeds the allowable current consumption.

In addition, when at least one of the case where the electric and electronic product 100 is inserted into the plug 51-53 and the case where the plug 51-53 is inserted and the corresponding electrical and electronic product 100 is in use, the corresponding outlet ( When the operation mode of 51-53) is determined to be the power cut mode, power supply to the corresponding outlet 51053 is automatically cut off, so that power to the corresponding outlet 51-53 can be forcibly cut off.

As such, the power cut mode is a mode in which the power to the corresponding outlets 51 to 53 determined as the power cut mode is forcibly terminated unconditionally. have.

To this end, when a plug of an electrical/electronic product is inserted into the plug insertion hole, the plug insertion detecting unit may detect this and transmit a corresponding signal to the operation control unit 30 .

Next, the operation controller 30 determines whether the operation mode of the corresponding outlet unit is the power cut mode before driving the switching unit for supplying power, and if the corresponding outlet unit is in the power cut mode, the operation controller 30 uses the switching unit to determine whether the corresponding outlet 51- Power supply to 53) may be cut off to force power cut to the corresponding outlets 51-53.

In addition, when at least one of the case where the electrical and electronic product 100 is connected to the outlet 51-53 and the case where the electrical and electronic product 100 connected to the outlet 51-53 is in use, the corresponding outlet 51-53 is in use. If the operation mode of 53) is set to the constant mode, as described above, power is always supplied to the corresponding outlet regardless of the current consumption current and the current total power consumption to prevent the power from being turned off (i.e., cut off).

However, even in an always-on mode in which power is supplied at all times, power to a corresponding outlet may be cut off in an emergency or by a user's forced shutdown operation. At this time, a power supply switch may be provided for each outlet 51 to 53, and the user may forcibly terminate power supply to the corresponding outlet 51 to 53 by turning off the power supply switch.

As another example, the user inputs a forced shutdown command to the operation control unit 30 using his/her user terminal, and uses the operation control unit 30 to forcibly terminate the supply of power to the corresponding outlets 51 to 53 set to the regular mode. can do. That is, the operation control unit 30, when a forced shutdown command for the corresponding outlet 51-53 is input from an external source such as the user input unit or the user terminal 70, even if the corresponding outlet 51-53 is set to the normal mode, the corresponding outlet It is possible to cut off the power to the unit.

To this end, when it is determined that the plug of the electrical/electronic product 100 is inserted into the plug insertion portion 511-531 of the corresponding outlet 51-53, the operation controller 30 operates the corresponding outlet 51-53. It can be determined whether the mode is always mode. When the corresponding outlet 51-53 is in the regular mode, the operation control unit 30 operates the switching unit 513-533 to maintain the supply of power to the corresponding outlet 51-53, thereby supplying power to the corresponding outlet 51-53. can always be supplied.

In this way, according to this example, since the power supply to the corresponding outlets 51-53 is controlled according to the total amount of electricity consumed as well as the instantaneous amount of electricity consumed, the user can plan the amount of electricity to be used by the user, thereby, Unnecessary use of electricity can be prevented and efficient use of electricity can be achieved.

In addition, since power is not supplied to the outlets 51-53 in which plugs are not inserted into the plug insertion holes 511-531 by the plug insertion detector 512-532 regardless of the operation mode, the outlets 51-53 ) Consumption of standby power consumed in is prevented.
