Description

Standby Power Breaking Receptacle and Operating Method

The present invention relates to a standby power cut-off outlet and its operation method, and in particular, even when the commercial power supply is suddenly cut off and then supplied again, the power supply state before the commercial power supply is cut off to match the state with the electric and electronic products. The present invention relates to a standby power cut-off outlet and a method of operating the same.

In general, to use electrical and electronic products such as computers, printers, multifunction devices, TVs, VTRs, audio, microwave ovens, air conditioners, etc. in a place such as an office or a home, a plug connected to the electrical and electronic products is connected to a receptacle. By doing so, a commercial power supply (for example, 330V, 220V, etc.) is supplied through the outlet to the corresponding electric and electronic products so that the electric and electronic products can be used.

In this case, the outlet is a connector for supplying commercial power, and in addition to the outlet, a multi-tap, a plug socket, a wall socket, and a central plug are used. And the like.

In the case of power control for electrical and electronic products, the remote controller is mainly used for the purpose of convenience of the user, that is, the user uses the remote control at a distance away from the electrical and electronic products. To turn the power on or off.

At this time, in order to perform the remote power control operation of the electrical and electronic products by the remote control, it is necessary to always supply a constant power to the electrical and electronic products through the plug connected to the outlet.

In this way, since most of the electrical and electronic products are used to be connected to the outlet through a plug, the plug is connected to the outlet, which is in a stand-by state where constant commercial power is always supplied to the electronic product. In this case, the commercial power supplied to the electrical and electronic products in the standby state is called standby power.

In other words, most of the electrical and electronic products, even in the standby state, commercial power is continuously supplied to the electrical and electronic products through the plugs connected to the outlets, resulting in power loss. Even if the power switch configured in the electrical and electronic products is turned off, the electrical power is always connected to the electrical and electronic products through the plug connected to the outlet, and thus the commercial power is continuously supplied to the electrical and electronic products, and the power loss of the standby power is reduced. This has led to a shortened life span of electrical and electronic products.

Therefore, in order to cut off the above-mentioned standby power, standby which can perform the same role, such as disconnecting a plug to which an electrical and electronic product is connected from an outlet, or turning off and shutting off a switch to cut off power supplied to the electrical and electronic product side. It has led to the development of power cut-off outlets.

The standby power cut-off outlet of the prior art remotely controls an outlet connected through a plug of the electrical and electronic product when the electric power is remotely controlled using the remote controller.

In other words, the standby power cut-off outlet is provided with a remote control signal receiving unit, and when the user remotely turns on the power of the electrical and electronic products using the remote control, the remote control signal transmitted from the remote control is first received through the remote control signal receiving unit. After the outlet connected to the electrical and electronic products is remotely turned on, the electrical and electronic products are supplied to the electrical and electronic products through the outlets to turn on the electrical and electronic products. On the other hand, when the user remotely turns off the power of the electrical and electronic products using the remote control, by receiving a remote control signal transmitted from the remote control through the remote control signal receiver to turn off the outlet connected to the electrical and electronic products remotely, Even in the standby state of electronic products, the power supply that is supplied is completely shut off to remove standby power generated from the electrical and electronic products.

However, such standby power cut-off outlets may have a power supply state (i.e., switching on / off state) and electrical power of the outlet when commercial power is suddenly cut off and then supplied again, such as when there is a power failure or when a user is forcibly unplugged. There is a state mismatch between the power supply state of the product (that is, the on / off state of the electrical and electronic products by the remote control signal), in which case the outlet is on but the electrical and electronic product is in the off state. In addition, there is a problem such that when the electrical outlet is turned off while the electrical and electronic products are off, the electrical and electronic products that receive the remote control signal first turn on and then turn off.

In particular, in the case of electrical and electronic products that store their own on / off state by a remote control signal, when the electrical and electronic product suddenly loses power while being driven, it remembers its own state as on. When the power is supplied again, the electric and electronic products are immediately driven. In the case of such electrical and electronic products, when the commercial power supply is suddenly cut off and then supplied again, the outlet is turned on by the remote control, but there is a problem that the electrical and electronic products that receive the remote control signal are turned off.

The technical problem to be achieved by the present invention is to solve the problems as described above, even if the commercial power supply is suddenly cut off and then supplied again by checking the power supply state before the commercial power supply is cut off the state with the electrical and electronic products An object of the present invention is to provide a standby power cut-off outlet and a method of operating the same.

In other words, the present invention stores the power supply state of the outlet (i.e., switching on / off state) in advance in the memory when commercial power is previously supplied to the outlet side, and thereafter, when the power failure or the user forcibly unplugs it. When the commercial power supply is not supplied to the electrical and electronic product, and then the commercial power is supplied again, the power supply state previously stored in the memory is checked, and then the same as the checked power supply state. By making the power supply state (that is, the on / off state of the electrical and electronic products by the remote control signal), even if the commercial power supply is suddenly disconnected and supplied again, it is implemented to match the state between the outlet and the electrical and electronic products.

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. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise. In addition, the terms “… unit”, “… unit”, “… module” described in the specification mean a unit that processes at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software. Can be.

Now, a standby power cut-off outlet and its operation method according to an embodiment of the present invention will be described in detail with reference to the drawings.

Standby power cut-off outlet according to an embodiment of the present invention is a connector that can receive a commercial power (for example, 330V, 220V, etc.) to supply to electrical and electronic products (for example, TV, etc.) -A tap, a plug socket, a wall socket, an outlet plug, or the like may be used. Alternatively, the plug may be provided in a plug of an electrical and electronic product (not shown in the drawing for convenience of description), and alternatively provided with a commercial power source. It should be understood that the wires (power supply lines for electrical and electronic products) may be provided.

1 is a block diagram illustrating a standby power cut-off outlet according to an embodiment of the present invention.

As shown in FIG. 1, the standby power cut-off outlet according to the embodiment of the present invention includes a remote control signal receiver 111, a power switch 112, a power converter 113, and a microcomputer 114. do.

The remote control signal receiver 111 uses an element such as an IR having a current consumption of about 10 (uA) to about 100 (uA) in the standby state for the minimum current consumption in the standby state. The remote control signal receiving unit 111 receives power (for example, 5V) from the power conversion unit 113 to drive and maintains a driving state at all times, and then transmits a remote control signal transmitted from the remote control under the control of the microcomputer 114 (that is, Receiving a power control signal for turning on / off power of an electrical and electronic product) and inputting the received remote control signal to the microcomputer 114. Alternatively, since the standby power cut-off outlet according to the embodiment of the present invention is mostly installed on an indoor wall that is not covered by electrical or electronic products in consideration of the aesthetics of the room or is not visible from the outside, the remote control signal of the remote control signal receiver 111 In order to improve the reception rate, it should be well understood that the remote control signal receiving portion of the remote control signal receiving unit 111 may be extended to be exposed to the outside, or may be installed on the remote control receiving unit side of the electrical and electronic product.

The power switch 112 may use, for example, an AC triac AC (triac AC), or an element such as a relay, a silicon controlled rectifier (SCR), or the like. The power switching unit 112 is switched on by the switching-on control of the microcomputer 114 to switch commercial power (ie, AC power) to electrical and electronic products (for example, a TV, etc.). It is switched off according to the switching-off control to fundamentally block commercial power that is being switched to electrical and electronic products. For example, the triac turns on commercial power to the TV when the microcomputer 114 applies a voltage to the gate side (i.e., outputs 'high' to the gate side). When the microcomputer 114 does not apply a voltage (ie, outputs 'low' to the gate side), the commercial power to the TV is turned off.

The power converter 113 receives commercial power (ie, AC power) and receives the input commercial power for the system (ie, the remote controller signal receiver 111, the microcomputer 114, the remote controller signal transmitter 115, etc.). It converts the DC power (for example, DC 5V) and inputs the converted DC power to the remote control signal receiving unit 111 and the microcomputer 114. At this time, the power conversion unit 113, for example, a rectifier circuit unit for receiving commercial power (that is, AC power) using a bridge diode to rectify the input commercial power and output the corresponding rectified voltage (for convenience of description) As not shown in the drawings). The power converter 113 is, for example, a voltage stabilizer for stabilizing the voltage rectified in the rectifier circuit part to a voltage having a fixed size (for example, 5V) using a regulator (not shown in the drawings for convenience of description). ) May be included. For example, the power converter 113 may connect an diode in parallel to the rectifier circuit to provide an overvoltage blocker (not shown in the drawings for convenience of description) to block excessive rectification voltage from flowing through the rectifier circuit. It may also include. For example, the power converter 113 may connect a plurality of capacitors in parallel to the overvoltage blocking unit, and use the voltage smoothing circuit unit to smooth the voltage input through the overvoltage blocking unit and output the voltage to the voltage stabilizing unit. Not shown). In the bridge diode, there is almost no current consumption, and in the case of the regulator, a power consumption of several to 10 (uA) in the standby state is used for low power.

Alternatively, the power conversion unit 113 may use an IC having an ultra-light weighted rectifier circuit that implements functions such as coils and transformers without using coils and transformers to minimize current consumption in a standby state. In this case, the supply current is only about 10 (uA).

The microcomputer 114 uses, for example, a device having a current consumption of about 10 (uA) to 100 (uA) during a control operation in the standby state to minimize current consumption in the standby state. It is driven by receiving power (for example, 5V) from the power source to maintain the driving state at all times.If the control operation is not performed in the driving state in order to further reduce current consumption, it sleeps itself (ie, sleep mode). In this mode, only 0.1 ~ 1 (uA) is consumed when the system enters the sleep mode even in the standby state.

In particular, the microcomputer 114 monitors the power supply to the electrical and electronic product side and stores the power supply state (that is, the switching on / off state) in the internal memory (for example, the flash memory) in advance, and then the power conversion unit 113. If the power supply (for example, 5V) is not suddenly supplied from the power supply and then supplied again, the power supply state stored in the internal memory is checked, and the identified power supply state and the power supply state to the electrical and electronic product side are matched.

In more detail, the microcomputer 114 checks the power supply state stored in the internal memory when the power is supplied from the power converter 113, and when the power supply state stored in the internal memory is 'OFF'. While maintaining the standby state (that is, the sleep mode state), when the remote control signal waveform is input from the remote control signal receiving unit 111, only the waveform input of the corresponding remote control signal is recognized as an interrupt and wake-up in the sleep mode (Wake-up). This reads the power control signal (or may include all different power control signals for each manufacturer) registered in the internal memory (for example, EEPROM), and from the remote control signal receiver 111 It is determined whether the input remote control signal and the power control signal read from the internal memory are the same. If the received remote control signal and the corresponding power control signal are not the same, the microcomputer 114 switches to the sleep mode state after a predetermined time (for example, 1 to 2 seconds) to minimize the current consumption to reduce the standby state. Keep it. On the other hand, if the received remote control signal and the read power control signal is the same, the microcomputer 114 performs a switching on control for turning on the power switching unit 112 to supply commercial power to the electrical and electronic products. At the same time, it registers its own power supply state (i.e., switching on / off state) in the internal memory as 'ON' state, and also after a certain time (e.g. 1 to 2 seconds) Sensing whether the current, voltage, or power of the power supply line is current to check whether the electrical and electronic products are being supplied with commercial power. In this case, when the electrical and electronic products are being driven, the microcomputer 114 checks again whether the electrical and electronic products are being driven after a predetermined time (for example, 1 to 2 seconds), or operates itself in a sleep mode to consume current. To maintain the standby state, then recheck the power supply state (ie, switching on / off state) stored in internal memory. In addition, the microcomputer 114 performs a switching-off control for turning off the power switching unit 112 when the electrical and electronic products are not being driven to cut off the commercial power, and at the same time, a power supply state of itself In other words, the switching on / off state is registered in the 'OFF' state to the internal memory, and after a certain time (for example, 1 to 2 seconds), the self is put into sleep mode again to minimize the current consumption to minimize the standby state. Then, check the power supply state (ie, switching on / off state) stored in the internal memory. Here, the internal memory is not shown in the drawings for convenience of description, and it should be well understood that a separate external memory may be used.

In addition, when the power supply state stored in the internal memory is 'ON', the microcomputer 114 performs switching on control to turn on the power switching unit 112 to supply commercial power to the electrical and electronic products. At the same time, it registers its own power supply state (i.e., switching on / off state) to the internal memory in the 'ON' state, and after a predetermined time (for example, about 1 to 2 seconds) has elapsed, By detecting the current, voltage, or power of the power supply line to the product side, it is checked whether the electrical and electronic products are currently powered by commercial power. In this case, when the electrical and electronic products are being driven, the microcomputer 114 checks again whether the electrical and electronic products are being driven after a predetermined time (for example, about 1 to 2 seconds) passes, or sleeps itself again. Operation to minimize the current consumption to maintain the standby state, and then recheck the power supply state (ie, switching on / off state) stored in internal memory. On the other hand, when the electrical and electronic products are not running, the microcomputer 114 performs a switching-off control for turning off the power switching unit 112 to cut off the commercial power and at the same time, the power supply state of its own. (I.e., switching on / off state) is registered in 'OFF' state to internal memory, and when a certain time (for example, 1 to 2 seconds) elapses, it operates itself back to sleep mode to minimize current consumption. After the standby state, the power supply state (that is, switching on / off state) stored in the internal memory is checked again.

Alternatively, after the predetermined time (eg, 4 to 5 seconds) has elapsed after the microcomputer 114 registers its own power supply state (ie, switching on / off state) to the 'ON' state, Detects the current, voltage, or power of the power supply line to the electrical and electronic products to check whether the electrical and electronic products are currently being supplied with commercial power, and the power switching unit 112 when the electrical and electronic products are not being driven. In addition to performing the switching off control to turn off the power supply state (ie, switching on / off state) to register the internal memory to the 'OFF' state. On the other hand, when the electrical and electronic products are running, the microcomputer 114 operates itself back to the sleep mode to minimize the current consumption so as to receive a remote control signal (ie, a power-off control signal) to receive a standby state (that is, sleep). Mode mode), and when the remote control signal waveform is input from the remote control signal receiving unit 111, it recognizes as an interrupt only by waveform input of the corresponding remote control signal and wakes up in the sleep mode, and is registered in the internal memory. The power control signal is read, and it is determined whether the remote control signal received from the remote control signal receiving unit 111 and the power control signal read from the internal memory are the same. In addition, the microcomputer 114 maintains the standby state again if the received remote control signal and the corresponding power control signal are not the same, whereas power switching when the received remote control signal and the corresponding power control signal are the same. At the same time as performing the switching-off control for turning off the unit 112, and registering its own power supply state (i.e., switching on / off state) in the 'OFF' state in the internal memory, a predetermined time After (eg, 1 ~ 2 seconds) elapses, it operates itself back to sleep mode to minimize the current consumption to maintain the standby state.

Alternatively, the microcomputer 114 may use a voltage measuring device, a current measuring device, a power measuring device (or a load measuring device), or the like for the current, voltage, power (or load) of the power supply line to the electrical and electronic product. It is also possible to check whether the measured value is greater than the preset reference value by measuring a lamp and the like, to determine whether the electric / electronic product is currently powered by commercial power. In addition, the standby power cut-off outlet according to an embodiment of the present invention may further include a voltage measuring unit, a current measuring unit, a power measuring unit (or a load measuring unit), etc. to measure whether the electrical and electronic products are being driven. .

Meanwhile, the standby power cut-off outlet according to the embodiment of the present invention may further include a remote control signal transmitter 115, a display unit 116, and a running button unit 117.

The remote control signal transmitter 115 performs an immediate operation according to the driving control of the microcomputer 114 and transmits the power control signal received from the microcomputer 114 to the electrical / electronic product as a remote control signal to turn on the electrical / electronic product. Or off).

The display unit 116 may use an LED, for example, and performs an operation such as displaying a remote control learning operation, displaying a remote control signal reception, or displaying a remote control signal transmission according to driving control of the microcomputer 114. . Alternatively, it should be understood that the device portion for outputting voice or sound may be used instead of the display portion 116.

The running button unit 117 learns a remote control signal (that is, a power control signal) transmitted from the remote control and registers it in the internal memory of the microcomputer 114 so that when the user presses the button, it is switched on to run the running mode. Notifies the microcomputer 114 of the input of the running button to perform.

Here, the microcomputer 114 controls the driving of the remote control signal transmitter 115, and after supplying commercial power to the electrical and electronic products and a predetermined time (for example, about 2 to 3 seconds) elapses, the microcomputer 114 reads from the internal memory. A power control signal is input to the remote control signal transmitter 115 so as to be transmitted to the electrical and electronic product as a remote control signal, and then, after a predetermined time (for example, 1 to 2 seconds), the power consumption is switched back to the sleep mode state. Minimize to maintain the standby state. In addition, the microcomputer 114 controls the driving of the display unit 116, and operates in a learning mode of the remote control signal waveform when the running button unit 117 is switched on, and is input from the remote control signal receiving unit 111 at this time. You can also register the received remote control signal (power control signal) to the internal memory, and then operate in the sleep mode after a certain time (for example, 1 to 2 seconds) to minimize the current consumption to maintain the standby state. do.

And after supplying the commercial power to the electrical and electronic products, the microcomputer 114 detects the current, voltage or power of the power supply line to the electrical and electronic products side to determine whether or not the electrical and electronic products are currently being supplied with commercial power. Check it. At this time, the microcomputer 114 does not transmit the power control signal read from the internal memory to the electrical and electronic products through the remote control signal transmitter 115 when the electrical and electronic products are being driven. On the other hand, the microcomputer 114 transmits the power control signal read from the internal memory as a remote control signal to the electrical and electronic product through the remote control signal transmitter 115 when the electrical and electronic product is not being driven.

Alternatively, after the predetermined time (for example, 1 to 2 seconds) has elapsed after the power supply control signal is sent to the electrical and electronic product, the microcomputer 114 may output the current, voltage, or the like of the power supply line to the electrical and electronic product. Detects power and checks whether electrical and electronic products are currently powered by commercial power. The microcomputer 114 transmits the power control signal read from the internal memory to the electrical and electronic product through the remote control signal transmitter 115 again for a predetermined time when the electrical and electronic product is not being driven. For example, after 1 to 2 seconds have elapsed, it is again checked whether the electrical and electronic product is being driven.

On the other hand, the standby power cut-off outlet according to an embodiment of the present invention, may be provided in the electrical and electronic products, when the remote control signal (that is, the power control signal) from the remote control by the power on button input of the remote control signal receiving unit ( When received at 111, the microcomputer 114 checks this and supplies commercial power to the electrical and electronic products through the power switching unit 112, thereby providing the microcomputer 114 without the components of the remote control signal transmitter 115. The main control unit of the electrical and electronic product may be driven to turn on the power of the electrical and electronic product. That is, the microcomputer 114 may directly notify the main controller of the electrical and electronic product in the same manner as the remote control signal (ie, the power control signal) received through the remote control signal receiver of the electrical and electronic product. Alternatively, it should be well understood that the remote control signal receiver 111 may be used in common with the remote control signal receiver of an electrical and electronic product.

Hereinafter, a method for operating a standby power cut-off outlet according to an embodiment of the present invention will be described in detail with reference to the flowcharts of FIGS. 2 to 3.

First, all different remote control signals (i.e., power control signals for remotely turning on / off power of electrical and electronic products) for each manufacturer manufacturing and producing a remote controller for controlling the electrical and electronic products remotely. The database is configured in advance and registered in advance in the internal memory of the microcomputer 114 or a separate external memory.

Alternatively, in order to learn and register a remote control signal (i.e., a power control signal) transmitted from the remote control, after the user presses the running button, the user presses the power button on the remote control so that the remote control signal is transmitted from the remote control. The running button unit 117 notifies the microcomputer 114 of the input of the running button to switch on to perform the running mode.

Accordingly, after detecting the input of the running button through the running button unit 117, the microcomputer 114 switches to the running mode state and receives a remote control signal (ie, a power control signal) from the remote control signal receiving unit 111. The registered remote controller signal is registered in the internal memory. At this time, the microcomputer 114 controls the driving of the display unit 116 to display the remote control learning operation.

After that, the microcomputer 114 switches itself to sleep mode after a predetermined time (for example, 1 to 2 seconds) has elapsed in order to further reduce the current consumption. When switching to, allow only a few to 10 (uA) of current consumption.

Next, the method for operating the standby power cut-off outlet according to an embodiment of the present invention will be described by dividing the case into a case in which the outlet operates only by a remote control signal and a case in which both the on / off operation is performed.

As a first example, a case of performing only an operation of receiving a remote controller signal (that is, a power-on control signal) transmitted from a remote controller will be described with reference to the flowchart of FIG. 2.

When commercial power is suddenly not supplied to the electrical and electronic product side, such as when there is a power failure or a user unplugs it forcibly, and the commercial power (ie, AC power) is supplied again, the power converter 113 is commercially available. Receives power and converts the received commercial power into DC power (eg, DC 5V) required for the system (ie, remote control signal receiver 111, microcomputer 114, remote controller signal transmitter 115, etc.). DC power is input to the remote control signal receiver 111 and the microcomputer 114.

For example, the bridge diode receives a commercial power (ie, AC power) and rectifies the input commercial power, and outputs the rectified voltage to the regulator side with the corresponding rectified voltage. At this time, the diode connected in parallel to the bridge diode blocks the excessive rectified voltage through the bridge diode, and a plurality of capacitors connected in parallel to the diode to smooth the voltage input through the diode to output to the regulator side, The regulator stabilizes the voltage rectified by the bridge diode to a voltage having a fixed size (for example, 5V) and supplies the voltage to the remote controller signal receiver 111 and the microcomputer 114.

At this time, the power converter 113 also periodically or intermittently or intermittently according to the control of the microcomputer 114 itself (or control using a timer) in order to further reduce the current consumed similarly to the microcomputer 114. This can be used to switch to the sleep mode (ie, a mode that does not perform an operation).

Thus, the remote control signal receiving unit 111 and the microcomputer 114 receives the power (for example, 5V) from the power conversion unit 113 to drive and maintains the driving state at all times. At this time, the microcomputer 114 checks information on its own power supply state (that is, switching on / off state) previously stored in the internal memory or a separate memory of the microcomputer 114 (S201).

Here, when the standby power cut-off outlet of the present invention operates for the first time, the initial value of its own power supply state (that is, switching on / off state) is set to 'OFF' state, or the internal memory of the microcomputer 114 or a separate unit. Make sure it is registered in memory.

If the power supply state registered in the memory in the above-described step S201 is 'OFF' state, that is, when the standby power cut-off outlet of the present invention operates for the first time, or when the electric / electronic product is turned off by a remote control signal, the normal switching is performed. When turned off, the microcomputer 114 maintains a standby state (ie, a sleep mode state) for receiving a remote control signal (ie, a power-on control signal) in the driving state described above (S202).

At this time, in the standby state of the above-described step S202, when the user transmits a remote control signal (that is, a power-on control signal) from the remote control by pressing the power button of the remote control to remotely turn on the power of the electrical and electronic products, the remote control signal receiver The remote control unit 111 receives power from the power conversion unit 113 and maintains a driving state at all times, and immediately after receiving a remote control signal (ie, a power-on control signal) transmitted from the remote control unit, the remote control received from the remote control unit. The signal is input to the microcomputer 114.

Then, the microcomputer 114 maintains the above-described sleep mode and checks whether the remote control signal waveform is input from the remote control signal receiver 111 (S203). At this time, when the remote control signal waveform is not input from the remote control signal receiving unit 111, the microcomputer 114 continues to maintain the sleep mode state of step S202 described above, and then the remote control signal waveform is input from the remote control signal receiving unit 111. Check to see if it works.

When the remote control signal waveform is input from the remote control signal receiving unit 111, the microcomputer 114 recognizes the interrupt as the waveform input of the corresponding remote control signal and wakes up in the sleep mode, thereby internal memory (for example, EEPROM). The power control signal (or may include all different power control signals for each manufacturer) registered in S (S204). At this time, the microcomputer 114 may control the driving of the display unit 116 to display the remote control signal reception.

The microcomputer 114 determines whether the remote control signal received from the remote control signal receiver 111 and the power control signal read from the internal memory are the same (S205). That is, the microcomputer 114 checks whether the remote control signal received from the remote control signal receiver 111 is a power control signal for turning on / off power of the electrical and electronic products.

Thus, if the remote control signal received from the remote control signal receiving unit 111 and the power control signal read from the internal memory in step S205 are not the same, the microcomputer 114 returns to step S202 described above without performing any operation. After a predetermined time (for example, 1 to 2 seconds) elapses, the user switches himself back to the sleep mode to minimize the current consumption to maintain the standby state.

On the other hand, if the remote control signal received from the remote control signal receiving unit 111 and the power control signal read from the internal memory in step S205 are the same, the microcomputer 114 switches on to turn on the power switching unit 112. The control is performed to supply commercial power to the electrical and electronic products (S206). At this time, the power switching unit 112 is switched on in accordance with the switching-on control of the microcomputer 111 to switch the commercial power to the electrical and electronic products to enable the electrical and electronic products to be driven.

At the same time, the microcomputer 114 registers its own power supply state (i.e., switching on / off state) to the internal memory of the microcomputer 114 or a separate memory in an 'ON' state (S207). Even when the power supply is suddenly cut off and then supplied again, it is used to match the state between the outlet and the electrical and electronic products.

At this time, the microcomputer 114 ignores the remote control signal input from the remote control signal receiving unit 111 after its own power supply state is registered in the 'ON' state. This is because, when receiving the remote control signal from the remote control signal receiving unit 111, the microcomputer 114 performs only the on operation, so that the remote control is distinguished from the remote control signal used to control the power of the electrical and electronic products.

Alternatively, when the standby power cut-off outlet according to the embodiment of the present invention further includes the remote control signal transmitter 115, the microcomputer 114 supplies the commercial power of step S206 described above to the electrical and electronic products, thereby providing the electrical and electronic products. After the predetermined time (for example, about 2 to 3 seconds) has elapsed, the power supply control signal read out from the internal memory is input to the remote control signal transmitter 115 so as to be transmitted to the electrical and electronic product. . Here, the reason why the remote control signal transmitter 115 transmits the remote control signal to the electrical / electronic product after a predetermined time (for example, 2 to 3 seconds) is that the electrical / electronic product is supplied with commercial power to boot the system to control the remote control signal. Since it takes some time until the state can be received, it may not be possible to directly receive the remote control signal from the remote control.

Accordingly, the remote control signal transmitter 115 performs an immediate operation according to the driving control of the microcomputer 114 and transmits a power control signal received from the microcomputer 114 to the electrical / electronic product as a remote control signal to supply power to the electrical / electronic product. Warm it up.

Then, the microcomputer 114 controls the driving of the display unit 116 to display the remote control signal transmission, and then returns to step S202 described above, and then after the predetermined time (for example, 1 to 2 seconds) has elapsed. Operates in the sleep mode to minimize the current consumption to maintain the standby state.

In addition, while the electric and electronic products that remember their own on / off state by the remote control signal are normally running, unplug the power cord to stop the commercial power supply, and force the outlet to turn off the outlet and the electric and electronic products. In the case where the state is made inconsistent, the microcomputer 114 supplies the commercial power source of step S206 described above to the electrical and electronic product, and then the current, voltage or power (or load) of the power supply line to the electrical and electronic product side, and the like. To monitor the current, voltage or power (or load) of the power supply to the electrical and electronic product.

At this time, as a result of the monitoring, it is determined whether the current, voltage, or power (or load) of the power supplied to the electrical and electronic product side is detected above a predetermined value to determine whether the electrical and electronic product is currently driven by commercial power. Do it.

If the electrical and electronic products are being driven, the electrical and electronic products, which have stored their own state by the remote control signal in the on state, are automatically turned on as soon as the commercial power is supplied, and the microcomputer 114 performs the above-described steps. The power supply state (ie, switching on / off state) of S207 is registered in the internal memory of the microcomputer 114 or a separate memory in the 'ON' state.

In addition, when the standby power cut-off outlet according to the embodiment of the present invention further includes a remote control signal transmitter 115, the microcomputer 114 transmits a power control signal read from the internal memory through the remote controller signal transmitter 115. Do not send remote control signals to electrical and electronic products.

On the other hand, if the electric and electronic products are not running, the electric or electronic products do not remember their own state by the remote control signal, or the commercial power supply suddenly occurs within the time when the electric and electronic products are turned off with the remote control and the outlet is stored. When not supplied, the microcomputer 114 transmits the power control signal read from the internal memory to the electrical and electronic product through the remote control signal transmitter 115 as a remote control signal, and then the electrical and electronic product receives commercial power. Check again whether it is running.

On the other hand, when the power supply state registered in the memory in the above-described step S201 is 'ON' state, that is, when the electrical and electronic products are being driven by commercial power through the outlet, the power outage or the user forcibly unplugs When the commercial power supply is suddenly not supplied to the electrical and electronic product side, the microcomputer 114 performs switching on control for turning on the power switching unit 112 to match the state. To supply (S208).

Accordingly, the power switching unit 112 is switched on according to the switching-on control of the microcomputer 111 to switch the commercial power to the electrical and electronic products so that the electrical and electronic products can be driven, and at the same time, the microcomputer 114 is magnetic By registering its power supply state (ie, switching on / off state) in the internal memory of the microcomputer 114 or a separate memory in the 'ON' state (S209), the commercial power supply is suddenly cut off and then supplied again. If possible, use it to match the condition between the outlet and the electrical and electronic equipment.

After a predetermined time (for example, about 1 to 2 seconds) has elapsed, the microcomputer 114 detects the current, voltage, or power (or load) of the power supply line to the electrical and electronic product side, and the current electricity. Check whether or not the electronic product is being driven by receiving commercial power (S210).

In addition, the microcomputer 114 returns to the above-described step S210 at a predetermined time interval (for example, about 10 seconds) even after performing the operation of the above-described step S207 to check whether the electrical and electronic products are not driven to the remote controller. It is also possible to check whether the electrical and electronic products are normally off.

At this time, if the electrical and electronic products are being driven in step S210 described above, the electrical and electronic products that have stored their own state by the remote control signal in the on state is automatically turned on as soon as the commercial power is supplied, the microcomputer 114 After a predetermined time (for example, about 1 to 2 seconds) has elapsed, the process returns to step S210 described above at a predetermined time interval (for example, about 10 seconds) to confirm that the electrical and electronic product is not driven. Check if the electrical and electronic products are normally turned off by the remote controller. Alternatively, the microcomputer 114 operates itself back to the sleep mode to minimize the current consumption to maintain the standby state, and then returns to the above-described step S201.

On the other hand, if the electrical and electronic products are not operating in the above-described step S210, the electrical or electronic products that do not remember their own state by the remote control signal, or the time when the electrical and electronic products off by the remote control and the outlet is stored in the on state When the commercial power is not suddenly supplied in the electronic device, or when the electrical and electronic products are normally turned off by the remote controller, the microcomputer 114 performs the switching off control to turn off the power switching unit 112 to cut off the commercial power. To (S211).

Accordingly, the power switching unit 112 is switched off according to the switching-off control of the microcomputer 111, and at the same time cut off the commercial power that is being switched to the electrical and electronic products, while the microcomputer 114 has its own power supply state. (Ie, the switching on / off state) is registered in the internal memory or a separate memory of the microcomputer 114 in the 'OFF' state (S212), so that the state between the electrical outlet and the electrical and electronic product is matched with each other.

After the predetermined time (for example, 1 to 2 seconds) has elapsed, the microcomputer 114 operates itself to the sleep mode to minimize the current consumption to maintain the standby state, and then returns to the above-described step S201. do.

Alternatively, in the case where the standby power cut-off outlet according to the embodiment of the present invention further includes a remote control signal transmitter 115, it is an electric and electronic product that does not remember its own state by the remote control signal, but supplies commercial power. In order to automatically turn on the electronic device as soon as it is received, the microcomputer 114 transmits the power control signal read from the internal memory to the electronic device through the remote control signal transmitter 115, if the electronic device is not being driven in step S210. Then, after a predetermined time (for example, about 1 to 2 seconds) has elapsed, the process may return to the above-described step S210 to check whether the electrical and electronic product is being driven by commercial power.

As a second example, a case of performing both on / off operations by receiving a remote controller signal (that is, a power on / off control signal) transmitted from a remote controller will be described with reference to the flowchart of FIG. 3.

Since the operation from step S301 to step S307 is similar to the operation from step S201 to step S207 described above, the description thereof will be omitted. At this time, the microcomputer 114 registers its own power supply state (ie, switching on / off state) in step S307 as 'ON' for a predetermined time (for example, about 4 to 5 seconds). The remote controller signal input again from the remote controller signal receiver 111 may be ignored. This is because the remote control is distinguished from the remote control signal (that is, the power-on control signal) used to control the power of the electrical and electronic products, and at the same time, when receiving a remote control signal from the remote control signal receiving unit 111 later, a microcomputer ( This is to distinguish the remote controller signal from the remote control signal (ie, the power-off control signal) for performing the off operation.

Alternatively, when the standby power cut-off outlet according to the embodiment of the present invention further includes the remote control signal transmitter 115, the microcomputer 114 supplies the commercial power of step S206 described above to the electrical and electronic products, thereby providing the electrical and electronic products. After the predetermined time (for example, about 2 to 3 seconds) has elapsed, the power control signal read out from the internal memory is input to the remote control signal transmitter 115 so as to be transmitted to the electric and electronic products. Turn on the power of electrical and electronic products.

Then, after registering the power supply state (i.e., switching on / off state) of step S307 to the 'ON' state for a predetermined time (for example, 4 to 5 seconds) (otherwise, the power control signal After a predetermined time (for example, 1 to 2 seconds) has elapsed after being sent to the electrical and electronic product, the microcomputer 114 has a current, voltage, or power (or load) of the power supply line to the electrical and electronic product. Detecting such as to check whether the current electrical and electronic products are being driven by commercial power (S308).

If the electrical and electronic products are not being driven in the above-described step S308, when the electrical and electronic products are not turned on by the remote control signal within a predetermined time (for example, 4 to 5 seconds) (or alternatively, the power control signal is In the case where the electronic device is not turned on, the microcomputer 114 performs the switching-off control for turning off the power switching unit 112, and thus the commercial power source that is being switched to the electrical and electronic product is inherently sourced. At the same time as blocking (S309), and registered its own power supply state (that is, switching on / off state) to the internal memory of the microcomputer 114 or a separate memory (S310), The process returns to step S302 described above.

Alternatively, in the case where the standby power cut-off outlet according to the embodiment of the present invention further includes the remote control signal transmitter 115, the microcomputer 114 may output the power control signal read from the internal memory to the remote controller signal transmitter 115. After a predetermined time (for example, 1 to 2 seconds) has elapsed after being sent back to the electrical and electronic product through, the process returns to step S308 described above to determine whether the electrical and electronic product is being driven by commercial power. You can also check again.

On the other hand, if the electrical and electronic products are being driven in the above-described step S308, when the electrical and electronic products are normally turned on by the remote control signal within a predetermined time (for example, 4 to 5 seconds) (otherwise, the power supply control signal When the electrical and electronic products are normally turned on by the electronic product, the microcomputer 114 operates itself to sleep mode to minimize the consumption current to receive a remote control signal (ie, a power off control signal). (Ie, sleep mode state) to be maintained (S311).

While maintaining the standby state of step S311 described above, when the user transmits a remote control signal (that is, a power-off control signal) from the remote control by pressing the power button of the remote control to remotely turn off the power of the electrical and electronic products, the remote control signal The receiving unit 111 receives power from the power conversion unit 113 and maintains the driving state at all times, and immediately after receiving the remote control signal (ie, the power-off control signal) transmitted from the remote control, the receiving unit receives the remote control signal. Input the remote control signal to the microcomputer (114).

Then, while maintaining the sleep mode described above, the microcomputer 114 checks whether the remote control signal waveform is input from the remote control signal receiver 111 (S312). At this time, the microcomputer 114 returns to the above-described step S311 when the remote control signal waveform is not input from the remote control signal receiving unit 111, while the remote control signal is input when the remote control signal waveform is input from the remote control signal receiving unit 111. The signal is recognized as an interrupt only by waveform input of the signal, wakes up in the sleep mode state, and the power supply control signal registered in the internal memory is read (S313).

The microcomputer 114 determines whether the remote control signal received from the remote control signal receiver 111 and the power control signal read from the internal memory are the same (S314). At this time, if the remote control signal received from the remote control signal receiving unit 111 and the power control signal read from the internal memory are not the same, the microcomputer 114 returns to step S311 described above, while the remote control received from the remote control signal receiving unit 111 is received. If the signal and the power control signal read from the internal memory are the same, switching off control for turning off the power switching unit 112 is performed to fundamentally block the commercial power being switched to the electrical and electronic product (S315).

At the same time, the microcomputer 114 registers its own power supply state (that is, the switching on / off state) to the internal memory of the microcomputer 114 or a separate memory (S316), After a predetermined time (for example, about 1 to 2 seconds) has elapsed, the self is put into sleep mode again to minimize the current consumption to maintain the standby state, and then return to the above-described step S302.

Alternatively, in the case where the standby power cut-off outlet according to the embodiment of the present invention further includes the remote control signal transmitter 115, the remote controller signal and the internal memory received from the remote controller signal receiver 111 in step S314 described above. If the read power supply control signal is the same, the microcomputer 114 transmits the power control signal (ie, the power-off control signal) read from the internal memory to the electric / electronic product through the remote control signal transmitter 115 to turn off the electric / electronic product. After a predetermined time (for example, 1 to 2 seconds) has elapsed, check whether the electrical and electronic products are being driven, and if the electrical and electronic products are being driven, send a power control signal again. On the other hand, if the electrical and electronic products are not running, it may return to step S315 described above to cut off the commercial power source.

On the other hand, when the power supply state registered in the memory in the above-described step S301 is 'ON' state, the microcomputer 114 returns to the above-described step S306.

As described above, when the power control signal of the remote controller is input in the initial standby state, the microcomputer 114 compares the input power control signal and the registered power control signal and compares the registered power control signal with the triac (that is, the power switching unit 112). Outputs high to the gate side of)) and enters the sleep mode at this moment, so the triac's gate will remain `` high '' even in sleep mode, allowing commercial power to continue to be supplied to the TV. After a time (for example, 2 to 3 seconds), the registered power control signal is sent to the electrical and electronic product to turn on the TV. In addition, when the power control signal of the remote controller is input again, the microcomputer 114 wakes up in the sleep mode and compares the input power control signal with the registered power control signal and outputs a 'low' to the gate side of the triac in the same case. After turning off the commercial power supplied to the TV side, it goes back to the sleep mode and keeps the current consumption to a minimum. As a result of the sleep mode operation of the microcomputer 114, the current consumed in the standby power cut-off outlet according to the exemplary embodiment of the present invention in the standby state is nearly consumed by the remote control signal receiver 111 and the power converter 113. As a whole, it can be seen that it is only about 10 to 100 (uA).
