Description
본 발명은 전자제품의 대기전력을 차단하기 위한 기술에 관한 것으로서, 특히, 전자제품의 전원스위치 하나로 대기전력을 완전히 차단하기 위한 대기전력 차단장치에 관한 것이다.The present invention relates to a technique for cutting off standby power of an electronic product, and more particularly, to a standby power cutoff device for completely cutting off standby power with one power switch of an electronic product.
전자 산업의 발달로 인하여 반도체를 이용한 디지털 전화기, 카메라, 전자수첩, 개인 휴대 정보 단말기, 스마트 폰, 노트북, TV 등과 같은 다양한 전자제품들이 보급되고 있는 추세이다. 이러한 반도체를 이용한 전자제품은 전원을 차단하여도 일정한 대기전력(Standby Electric Power)을 소비하게 된다. 여기서, 대기전력(Standby Electric Power)이란 각종 전자제품에 있어 전원 플러그가 통상적으로 콘센트에 연결되어 있는 상태에서 상기 전자제품의 미사용 시에도 계속해서 소모되고 있는 전력을 지칭한다.Due to the development of the electronic industry, a variety of electronic products such as digital phones, cameras, electronic notebooks, personal digital assistants, smart phones, laptops, TVs, etc. using semiconductors are being spread. Electronic products using such a semiconductor consume a certain standby power even when the power is cut off. Here, standby power refers to power that is continuously being consumed even when the electronic product is not used in a state where a power plug is generally connected to an outlet in various electronic products.
최근에는 전자제품의 사용이 늘어나면서 가정 및 회사에서 소비되는 전력의 일부가 대기전력으로 인하여 낭비되어 전력손실이 커지고 있는 실정이다. 통계에 따르면, 소모되는 대기전력으로 인해 연간 수 천억 원의 경제적인 손실이 발생되고, 국가적으로는 불필요하게 낭비되는 전력을 생산하기 위하여 화석연료의 사용에 따른 이산화탄소가 지속적으로 발생하게 되고, 이것은 궁극적으로 환경오염의 요인이 되는 문제가 초래되는 것이다. 이에 따라, 대기전력의 효과적인 차단이 각종 전자제품의 에너지 효율을 높이는데 있어서 중요한 문제로 언급되고 있다.Recently, as the use of electronic products increases, a part of the power consumed by homes and businesses is wasted due to standby power, and the power loss is increasing. According to the statistics, the standby power consumption consumes hundreds of billions of dollars annually, and nationally, carbon dioxide is continuously generated by the use of fossil fuels to produce unnecessary waste. As a result, the problem of causing environmental pollution is brought about. Accordingly, effective blocking of standby power has been mentioned as an important problem in improving energy efficiency of various electronic products.
한편, 대기전력을 줄이기 위한 방법으로 콘센트에 별도의 스위치를 설치하여 전원을 온/오프 제어하는 방법이 널리 사용되고 있다. 그러나, 전자제품 전원 차단 시에 상기 별도로 설치된 스위치 사용이 불편하여 큰 실효성을 거두지 못하고 있다. 별도의 스위치 기능이 추가된 콘센트를 사용하지 않고도 전자제품 전원의 온/오프에 따라 대기전력을 자동으로 차단하는 대기전력 차단장치 및 방법에 관한 일 예로는 본 출원인에 의해 선출원된 대한민국 등록특허 제10-0945210호(명칭: 대기전력 차단 장치 및 그 제어 방법, 발명자: 김창호, 출원일 2009년08월05일)에 개시된 바를 예를 들 수 있다. 이러한 대기전력 차단장치를 부착하기 위해서는 상기 대기전력 차단장치의 두께가 기존의 전자제품 전원스위치 보다 두껍기 때문에 기구물의 설계를 변경해야만 하는 번거로움이 있다. 또한, 기구물의 설계를 변경하는 비용이 추가적으로 발생할 수 있기 때문에 원가가 상승하는 문제점이 발생한다. Meanwhile, as a method for reducing standby power, a method of controlling power on / off by installing a separate switch in an outlet has been widely used. However, the use of the separately installed switch at the time of power off the electronic products is inconvenient and does not achieve great effectiveness. An example of a standby power cut-off device and method for automatically shutting off standby power according to on / off of power of an electronic product without using an outlet to which a separate switch function is added, is described in Korean Patent Application No. 10 filed by the present applicant. Examples include -0945210 (name: standby power interruption device and control method thereof, inventor: Chang Ho Kim, filing date of August 05, 2009).

In the state where the power supply of the electronic product 50 is completely cut off, that is, the contacts k11 and k13 of the latching relay K1 of the power supply / interruption switching unit 310 are open, and the contacts k12 and k14 are also open. The contacts k20 and k22 of the power supply relay k2 of the power switch converter 330 may be connected, and the contacts k23 and k25 may be connected. At this time, when the user 'on' the power switch PW of the electronic product 50 to use the electronic product 50, the power 'on' signal is transmitted through the pins 2 and 3 of the connector 40. The conversion unit 330 may be provided. Thus, the power 'on' signal may be provided to the triggering unit 320 through the power supply relay k2 of the power switch conversion unit 330. The power 'on' signal may be generated as power through the capacitor C1 of the triggering unit 320. The power may be supplied to the bridge D to generate power Va through the capacitor C2. do.

Contacts k12 and k14 can be connected. In an embodiment of the present invention, by using the latching relay K2, the connected state of the connected relay contacts is continuously maintained so that the input portion of the power supply 510 of the electronic product 50 is connected through the pins 4 and 5 of the connector 40. Allow power to continue to be applied to (I1, I2). As a result, the power supply unit 510 may generate power Vcc and power Vb necessary for the electronic product 50. However, in the case of the power supply Va, the power switch PW may be generated only for a certain period of time when the power switch PW is 'on', and may be extinguished during a period in which the power switch PW is not 'on'.
여기서, 전자제품(50)의 전원부(510)에 전원이 공급되어 전원(Vcc)이 생성되면, 커넥터(40)의 핀(7,8)을 통해 전원스위치변환부(330)에 상기 전원(Vcc)이 공급될 수 있다. 이때, 릴레이코일(k2c1)에 전원(Vcc)이 공급되어 전원차단릴레이(K2) 접점 k21, k22가 접속되고, 접점 k24, k25가 접속될 수 있다. 이로 인해, 트리거링부(320)에서 생성된 전원(Va)가 더 이상 트리거링부(320)에서 생성되지 않아, 전원공급/차단스위칭부(310)의 래칭릴레이코일(k1c1)에 공급되던 전원(Va)이 차단될 수 있다. Here, when power is supplied to the power supply unit 510 of the electronic product 50 to generate the power supply Vcc, the power supply Vcc is supplied to the power switch conversion unit 330 through the pins 7 and 8 of the connector 40. ) Can be supplied. At this time, the power supply Vcc is supplied to the relay coil k2c1 so that the power cutoff relay K2 contacts k21 and k22 may be connected, and the contacts k24 and k25 may be connected. As a result, the power Va generated by the triggering unit 320 is no longer generated by the triggering unit 320, and thus, the power Va that is supplied to the latching relay coil k1c1 of the power supply / blocking switching unit 310. ) May be blocked.
한편, 전자제품(50)을 사용하지 않기 위해 사용자가 전자제품(50)의 전원스위치(PW)를'오프'하면, 커넥터(40) 2,3단자를 통해 상기 전원스위치변환부(330)로 전원 '오프' 신호가 제공될 수 있다. 이러한 전원 '오프'신호는 전원차단릴레이(K2)의 이미 접속된 접점 k21, k22과 연결된 저항R1을 통해서 제어부(520)의 입력단자(I3)의 입력값이'하이'상태에서 '로우'상태로 전환될 수 있다. 상기 입력값이'로우'상태가 되면 제어부(520)의 입력단자(I3)는 전원'오프'신호로 판단하여 출력단자(O1)으로 출력값을 '하이'로 출력하여 전원공급/차단스위칭부(310)의 트랜지스터(Q1)를 '온'시켜 래칭릴레이코일(k1c2)에 전원이 흐르도록하여 래칭릴레이(K1) 접점 k11, k13이 '오픈'되도록 할 수 있다. 이때 접점 k12, k14도 함께 '오픈'되어 전자제품(50)의 전원부(510)로 제공되는 전원공급이 차단될 수 있다. 이때, 전원부(510)에서 생성되는 전원(Vcc)이 더 이상 생성되지 않아 전원스위치변환부(330)의 릴레이코일(k2c1)로 공급되던 전원(Vcc)이 차단되어 전원차단릴레이(K2) 접점 k21, k22가 오픈되어 전원공급릴레이(K2) 접점 k20, k22가 접속되고, 전원차단릴레이(K2)접점 k24, k25가 오픈되어 전원공급릴레이(K2) 접점 k23, k25가 접속될 수 있다. 한편, 전자제품(50)의 전원스위치(PW)를 직접 '오프'하지 않고, 소프트웨어에서 종료하여 전자제품(50)을 '오프'하는 방법을 사용할 경우, 제어부(520)가 종료를 자체적으로 판단하여 상술한 바와 같이 출력단자(O1)의 출력값을 '하이'로 하여 전원'오프'로 판단되어 전원이 차단될 수 있도록 한다.On the other hand, when the user 'off' the power switch PW of the electronic product 50 in order not to use the electronic product 50, the power switch conversion unit 330 through the connector 40, 2, 3 terminals. A power off 'signal' may be provided. The power 'off' signal is 'low' when the input value of the input terminal I3 of the controller 520 is 'high' through the resistor R1 connected to the contacts k21 and k22 already connected to the power cutoff relay K2. Can be switched to. When the input value is 'low' state, the input terminal I3 of the control unit 520 determines that the power is 'off' signal, and outputs the output value as 'high' to the output terminal O1 to supply the power / cutoff switch ( The transistor Q1 of 310 may be 'on' to allow power to flow through the latching relay coil k1c2 so that the latching relay K1 contacts k11 and k13 may be 'open'. In this case, the contacts k12 and k14 may also be “opened” to cut off the power supply provided to the power supply unit 510 of the electronic product 50. At this time, since the power Vcc generated by the power supply unit 510 is no longer generated, the power supply Vcc supplied to the relay coil k2c1 of the power switch conversion unit 330 is cut off, thereby shutting off the power cutoff relay K2. The power supply relay K2 contacts k20 and k22 may be connected to each other, and the power supply relay K2 contacts k24 and k25 may be opened to connect the power supply relay K2 contacts k23 and k25. On the other hand, when using the method of turning off the electronic product 50 by shutting down in the software without directly 'off' the power switch PW of the electronic product 50, the control unit 520 determines the termination itself. As described above, the output value of the output terminal O1 is set to 'high' to determine that the power is 'off' so that the power can be cut off.

도 6을 참조하여, 본 발명의 다른 실시예에 따른 대기전력 차단장치를 구비하는 전원케이블의 동작을 상세하게 설명한다. Referring to Figure 6, it will be described in detail the operation of the power cable having a standby power cut-off device according to another embodiment of the present invention.
전자제품(50)의 전원이 완전히 차단된 상태는 즉, 전원공급/차단스위칭부(340)의 릴레이(K1)의 접점 k11, k13이 오픈 상태이고, 접점 k12, k14 또한 오픈 상태이다. 전원스위치변환부(330)의 전원공급릴레이(k2)의 접점 k20, k22이 접속된 상태이고, 접점 k23, k25가 접속된 상태일 수 있다. 이때, 전자제품(50)을 사용하기 위해 사용자가 전자제품(50)의 전원스위치(PW)를'온'하면, 커넥터(40) 핀(2,3)을 통해 전원'온' 신호가 전원스위치변환부(330)로 제공될 수 있다. 이로 인해, 전원스위치변환부(330)의 전원공급릴레이(k2)를 통해 전원 '온'신호가 트리거링부(320)로 제공될 수 있다. 이러한 전원 '온'신호는 트리거링부(320)의 콘덴서(C1)을 통해서 전원으로 발생될 수 있는데 상기 전원은 브릿지(D)에 공급되어 콘덴서(C2)를 통해 전원(Va) 를 생성할 수 있도록 한다. 생성된 전원(Va)가 전원공급/차단스위칭부(340)의 릴레이코일(k1c1)에 공급되어, 상기 릴레이코일(k1c1)과 연결된 릴레이(K1)의 접점 k11, k13이 접속되고, 접점 k12, k14가 접속될 수 있다. 본 발명의 다른 실시예에 따라 커넥터(40) 4,5 단자를 통해 전자제품(50) 전원부(510) 입력단자(I1, I2)로 전원이 일정기간 동안 인가될 수 있도록 한다. 이로 인해, 전원부(510)는 전자제품(50)에 필요한 전원(Vcc)과 전원(Vb)을 생성할 수 있다. 이때, 전원(Va)는 전원스위치(PW)가 '온'되는 일정기간 동안만 발생되고, 전원스위치(PW)가 '온'되지 않은 기간 동안은 소멸될 수 있다. 따라서, 전원(Va)가 소멸되면, 릴레이(K1) 접점 k11, k13이 오픈되고, 접점 k12, k14가 오픈되어 전원이 차단되게 된다. 여기서 전원부(510)로부터 일정 기간 동안 발생된 전원(Vcc)가 전자제품(50) 제어부(520)에 제공되면, 제어부(520)는 출력단자(O1)를 통해 출력값을'하이'로 출력하여 전원공급/차단스위칭부(340)의 트랜지스터(Q1)를 통해 릴레이코일(K3)이 에너자이즈 되어 릴레이(K3) 접점 k31, k33 이 접속되고, 접점 k32, k34가 접속되어 전원부(510) 입력단자(I1, I2)로 전원이 계속 공급되어 전자제품(50)이 정상동작을 할 수 있도록 한다.In the state where the power supply of the electronic product 50 is completely cut off, that is, the contacts k11 and k13 of the relay K1 of the power supply / blocking switching unit 340 are open, and the contacts k12 and k14 are also open. The contacts k20 and k22 of the power supply relay k2 of the power switch converter 330 may be connected, and the contacts k23 and k25 may be connected. At this time, when the user 'on' the power switch PW of the electronic product 50 to use the electronic product 50, the power 'on' signal is transmitted through the pins 2 and 3 of the connector 40. The conversion unit 330 may be provided. Thus, the power 'on' signal may be provided to the triggering unit 320 through the power supply relay k2 of the power switch conversion unit 330. The power 'on' signal may be generated as power through the capacitor C1 of the triggering unit 320. The power may be supplied to the bridge D to generate power Va through the capacitor C2. do. The generated power Va is supplied to the relay coil k1c1 of the power supply / blocking switching unit 340 so that the contacts k11, k13 of the relay K1 connected to the relay coil k1c1 are connected, and the contacts k12, k14 may be connected. According to another exemplary embodiment of the present invention, power may be applied to the input terminals I1 and I2 of the power supply unit 510 of the electronic product 50 through the 4 and 5 terminals of the connector 40 for a predetermined period of time. As a result, the power supply unit 510 may generate a power supply Vcc and a power supply Vb necessary for the electronic product 50. In this case, the power supply Va may be generated only for a certain period of time when the power switch PW is 'on', and may be extinguished during a period in which the power switch PW is not 'on'. Therefore, when the power supply Va disappears, the relays K1 and the contacts k11 and k13 are opened, and the contacts k12 and k14 are opened to cut off the power supply. Here, when the power Vcc generated for a predetermined period from the power supply unit 510 is provided to the control unit 520 of the electronic product 50, the control unit 520 outputs the output value as 'high' through the output terminal O1 to supply power. The relay coil K3 is energized through the transistor Q1 of the supply / blocking switching unit 340 to connect the relays K3 and k33 and k33, and the contacts k32 and k34 are connected to the power supply unit 510. Power is continuously supplied to (I1, I2) to allow the electronics 50 to operate normally.
여기서, 전자제품(50)의 전원부(510)에 전원이 공급되어 전원(Vcc)이 생성되면, 커넥터(40)의 핀(7,8)을 통해 전원스위치변환부(330)에 전원(Vcc)이 공급될 수 있다. 이로 인해, 릴레이코일(k2c1)에 전원(Vcc)이 공급되어 전원차단릴레이(K2) 접점 k21, k22가 접속되고, 접점 k24, k25가 접속될 수 있다.Here, when power is supplied to the power supply unit 510 of the electronic product 50 to generate the power supply Vcc, the power supply Vcc is supplied to the power switch conversion unit 330 through the pins 7 and 8 of the connector 40. Can be supplied. For this reason, the power supply Vcc is supplied to the relay coil k2c1, the power cutoff relay K2 contact k21, k22 can be connected, and the contact k24, k25 can be connected.
한편, 전자제품(50)을 사용하지 않기 위해 사용자가 전자제품(50)의 전원스위치(PW)를'오프'하면, 커넥터(40) 2,3단자를 통해 상기 전원스위치변환부(330)로 전원 '오프' 신호가 제공될 수 있다. 이러한 전원 '오프'신호는 전원차단릴레이(K2)의 이미 접속된 접점 k21, k22과 연결된 저항R1을 통해서 제어부(520)의 입력단자(I3)의 입력값이'하이'상태에서 '로우'상태로 전환될 수 있다. 상기 입력값이'로우'상태가 되면 제어부(520)의 입력단자(I3)는 전원'오프'신호로 판단하여 출력단자(O1)으로 출력값을 '하이'로 출력하여 전원공급/차단스위칭부(310)의 트랜지스터(Q1)를'오프'시켜 릴레이코일(K3)를 디에너자이즈 되어 릴레이(K3) 접점 k31, k33이 오픈되고, 접점 k32, k34도 마찬가지로 오픈되어 전원공급이 차단될 수 있다. 이때, 전원부(510)에서 생성되는 전원(Vcc)이 더 이상 생성되지 않아 전원스위치변환부(330)의 릴레이코일(k2c1)로 공급되던 전원(Vcc)이 차단되어 전원차단릴레이(K2) 접점 k21, k22가 오픈되어 전원공급릴레이(K2) 접점 k20, k22가 접속되고, 전원차단릴레이(K2)접점 k24, k25가 오픈되어 전원공급릴레이(K2) 접점 k23, k25가 접속될 수 있다.On the other hand, when the user 'off' the power switch PW of the electronic product 50 in order not to use the electronic product 50, the power switch conversion unit 330 through the connector 40, 2, 3 terminals. A power off 'signal' may be provided. The power 'off' signal is 'low' when the input value of the input terminal I3 of the controller 520 is 'high' through the resistor R1 connected to the contacts k21 and k22 already connected to the power cutoff relay K2. Can be switched to. When the input value is 'low' state, the input terminal I3 of the control unit 520 determines that the power is 'off' signal, and outputs the output value as 'high' to the output terminal O1 to supply the power / cutoff switch ( The relay coil K3 may be deenergized by 'off' the transistor Q1 of 310 to open the relays K3 and the contacts k31 and k33, and the contacts k32 and k34 may be opened in the same manner to cut off the power supply. . At this time, since the power Vcc generated by the power supply unit 510 is no longer generated, the power supply Vcc supplied to the relay coil k2c1 of the power switch conversion unit 330 is cut off, thereby shutting off the power cutoff relay K2. The power supply relay K2 contacts k20 and k22 may be connected to each other, and the power supply relay K2 contacts k24 and k25 may be opened to connect the power supply relay K2 contacts k23 and k25.
