Therefore, when the user authenticates the user through the second user authentication unit 540 of the office control apparatus 500 to enter the office, the individual standby power driver 580 and the individual light driver ( 590 to be powered to drive them.

Subsequently, the outlet or power strip assigned to the user is kept in a state where the power supply is cut off, and then the standby power cut-off state is received while the power is supplied. It is determined that the standby state, the power delivered to the electric device is cut off.

The lamp assigned to the user may be kept in a state in which the power supply is cut off and then turned on.

On the other hand, when the ambient light is determined to be bright through the illumination sensor unit 550 provided in the office control apparatus 500, the individual light driver 590, the power supply is cut off, even if the user authentication is individual light driver 590 The power supply is cut off.

Therefore, when it is determined that the surroundings are bright by the illuminance sensor unit 550, even if user authentication is performed through the second user authentication unit 540, the lamp assigned to the user is in an OFF state. maintain.

On the other hand, if the time is determined to be dark through the ambient light sensor unit 550 over time, the power supply is automatically made to the individual light drive unit 590 that the power supply was cut off, the lamp assigned to the user It turns on.

When the user exits the office to leave the office to authenticate the user through the second user authentication unit 540 of the office control device 500, the individual standby power driver 580 and the individual light driver 590 assigned to the user. ), The applied power is cut off to stop their operation.

Accordingly, the power supplied to the individual standby power driver 580 is cut off and the standby power cut off is released.

At this time, the power supplied to the outlet or the power strip is also cut off, so that the power supplied to the electrical outlet connected to the outlet and the power strip is also cut off.

Subsequently, when the floor control device 300 receives a signal indicating that all power supplied to the office is cut off through the second communication unit 330, the power source driving unit 370 is driven to supply power to the corresponding floor. Block all

In the management server 200, the standby power cut-off state and the state of the lamp of the office are displayed for each floor, and each of them can be controlled, and the power supplied to each floor through the floor-specific control device 300 is cut off, and the main The standby power driving unit 270 and the main light driving unit 280 are driven to cut off all power supplied to the entire building.

For reference, FIG. 7 is a block diagram illustrating another example of the individual standby power driver, and illustrates remotely controlling the standby power cutoff power tap using a remote controller (not shown).

As shown in FIG. 7, the standby power cut-off power strip includes a power supply unit 601, a rectifier 602, a current detector 603, a ground fault detector 604, a microcomputer 605, a standby power detector 606. And a switch 607, a display unit 608, an RF receiver 609, a relay 610, an outlet 611, and a DIP switch 612.

The outlet 611 is provided with a plurality of inserts of the general standard for plugging in the home appliances, the power supply switch 607 for allowing a current to flow in the outlet 611, the display unit for checking the power supply state ( 608 is coupled to the housing in which it is formed.

The rear of the outlet 611 of the housing is connected to the wall outlet plug is connected to receive power.

Power is supplied to the home appliance through the plug inserted into the insert according to the ON operation of the switch 607 or the remote controller, and power to the plug is cut off from the insert according to the OFF operation.

The display unit 608 indicates whether the power supply state or the standby power cut-off state, and has a light emitting diode part in the housing indicating the operation state, and emits the light emitting diode in the power supply state and the standby power cut-off state. In this case, the light emitting diode blinks.

The display unit 608 may be configured to display the overload state through the light emitting diode when the overload is overload, and may display whether the power supply state, the standby power cutoff state, or the overload state is performed by sound through the speaker or the buzzer.

The power supply unit 601 supplies power to the outlet 611 through the relay 610.

The power supply unit 601 transmits AC power to the rectifier 602 so as to easily supply power to the microcomputer part 605, and the rectifier 602 rectifies the transmitted power and transfers the power to the microcomputer 605.

The ground fault detecting unit 604 detects whether there is a leakage current from the power supply unit 601, and thus transmits a ground fault signal to the microcomputer 605 when a leakage current occurs.

The current detection unit 603 detects these current values when using the home appliances that are plugged into the outlet 611, and then transfers the detection signals to the microcomputer 605.

The standby power detection unit 606 detects the standby power generated in the initial state in which the home appliance is plugged into the outlet 611 and transmits the standby power value to the microcomputer 605.

In this case, the standby power detection unit and the current detection unit have the same configuration, and are expressed differently so as to distinguish and classify the standby power value and the current value among the currents transferred from the outlet to the microcomputer.

That is, the current sensing unit and the standby power sensing unit 606 are current sensing units consisting of a current transformer (CT), a diode, a smoothing capacitor, a zener diode, and a resistor, and the home appliances in which the current transformer CT is connected to an outlet. It functions to detect the current of the loads in proportion to the power supplied to the diode, and the diode and the smoothing capacitor rectify and convert the current of the detected loads into a direct current signal, so that the currents of the loads detected through the resistance are converted into voltages. It enters the AD converter.

At this time, the input voltage to the AD converter protects the microcomputer through the zener diode so as not to exceed 5V.

In other words, the current coming through the current transformer (CT) is converted into a voltage to be compared in the microcomputer.At this time, if the current value is small, the voltage input to the AD of the microcomputer is low, so it is determined that the home appliance is in standby power or off mode. If the current value is large, it is judged that the home appliance is in use because the voltage input to the AD of the microcomputer is high, and it is expressed as comparing the power value and the current value for the user's understanding.

Therefore, when the load is not used, it is judged as standby power because the voltage is low, and when the load is used, it is judged as the load power and the power is supplied to and disconnected from the outlet.

In the microcomputer, it is determined whether to use the home appliance by comparing the voltage coming into the AD through the current transformer (CT), but the principle is that the current transformer (CT) detects the current, so that it can be judged by comparing the current. Therefore, since the standby power or the load power is determined, the standby power can be compared and judged.

The switch 607 is a switch part capable of turning on / off the main power by itself, and transmits a signal to the microcomputer 605 to turn on / off the power supply 220V to the outlet 611.

The RF receiver 609 may receive an ON / OFF signal from an RF remote controller regardless of the direction, and the signal transmitted to the RF receiver 609 is transmitted to the microcomputer 605 so that the switch unit 607 is received. Performs the same function as.

The RF receiver 609 may be replaced with an infrared receiver that receives an infrared signal.

The relay 610 is ON / OFF in response to a command from the microcomputer 605, and applies a power supply 220V to the outlet 611 as it becomes ON.

The DIP switch 612 is a switch for controlling the time to shut off the power supply of the outlet 611 when the standby power flows.

The microcomputer 605 is supplied with power through the rectifying unit 602, a current value from the current detecting unit 603, a short circuit signal from the ground fault detecting unit 604, and a standby power detecting unit 606. The standby power value, the switch 607 and the ON / OFF signal from the RF receiver 609 is received.

The microcomputer 605 receiving the above signals controls the relay 610 according to the value to open and close the power supply circuit of the outlet 611.

That is, when the earth leakage signal of the earth leakage detection unit 604 is received, the power of the power supply unit 601 is not transmitted to the outlet 611 through the relay 610, and the current value from the current detection unit 603. When receiving the relay 610 to turn on the power of the power supply unit 601 to be delivered to the outlet 611 to operate the home appliances.

In addition, the standby power value received from the standby power detection unit 606 is stored and stored, and if greater than or equal to the current value from the current detection unit 603, the relay 610 is turned off to the current to the outlet 611 Does not flow.

In addition, when the power is supplied to the outlet, the light emitting diode of the display unit 608 is turned on and the light emitting diode is turned off according to the standby power blocking state.

In this case, when using an individual outlet, that is, using only one product per household, it is determined whether to use the product of the home appliance, and the power is supplied to and disconnected from the outlet. When using a multi-tap, a plurality of electronic products can be used, but the standby power of each home appliance is not known.

However, when power is supplied to the output of the standby power cut-off outlet, the initial value of the voltage coming into AD from the microcomputer is memorized. If it is determined by the microcomputer and the load is not used, the microcomputer determines that the load is not used because the voltage input to AD is the same as when the power was initially supplied.

Therefore, when a plurality of home appliances are connected through a plurality of outlets, the standby power for each home appliance may not be known, but the overall standby power may be known.

On the other hand, if the current sensing unit 603 is broken, the relay can be turned off so that the power supply is cut off to prevent fire, and the display unit indicates that the power supply is cut off so that the user intuitively knows the product defect. To help.

For example, there are two cases where it is judged as a failure through the current detector. The first symptom is the same as when the overload occurs. The AD output value of the current detector is maximized. It is the case that there is no AD output value of current sensing part.

When any one of the two cases described above occurs, the microcomputer detects this and may notify the light emitting diode, the buzzer, or the speaker through the display unit.

In addition, standby power can be intelligently cut off from the standby power blocking power strip. For example, one electric device may be connected to the power strip, and another electric device may be connected during use, and the initial power supply is not connected to the power strip. Assume

First, the power supply is activated by activating an outlet when the electric device is not connected to the power strip.

The multi-tap may be provided with a limit switch that is a detection switch. 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 power is supplied to the electronic device inside the multi-tap.

Subsequently, when the plug of the electric device is connected to the outlet, after about 1 second to 2 seconds are counted, 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, is set. .

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 where the primary correction value is set, the standby power is cut off after about 30 seconds have been counted.

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, when an electrical device such as a fan using a rotary switch is connected to the power strip or initially, And when two or more electrical devices are 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 first comparison value based on the first comparison value.

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 will proceed.

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, the standby power cutoff reference value.

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, when the standby power cutoff value is initially set, power consumption of an electric device connected to a power strip is made, and additionally another electric device is connected and used, the power consumed by including an additional connected electric device is at an arbitrary allowable range. If included, 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, the standby power cut-off power strip may be provided with a manual switching button (not shown). When the manual switching button is turned on to switch to the manual mode, the plug of the electrical device is connected to an electrical device connected to the power strip. The standby power value 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.

In the above description, the present invention has been described with reference to preferred embodiments, but the present invention is not necessarily limited thereto, and a person having ordinary skill in the art to which the present invention pertains does not depart from the technical spirit of the present invention. It will be readily appreciated that various substitutions, modifications and variations can be made.
