Description

비상조명등용 배터리 과충방전 제어장치{Battery Control Unit For Extraordinary Lighting Lamp}Battery Overcharge / Discharge Control Device for Emergency Lightings {Battery Control Unit For Extraordinary Lighting Lamp}

본 발명은 배터리 충전완료후 전류가 제어되어 과충전을 방지하고 배터리 방전종료후 과방전 방지회로부에 의해 비상점등이 차단되는 비상조명등장치에 관한 것으로, 더욱 상세하게는 대용량으로 예컨데 5 A 이상의 배터리를 안정화상태로 충방전이 가능하고 정전시 고휘도의 비상조명등을 장시간 점등시킬 수 있는 비상조명등용 배터리 과충방전 제어장치에 관한 것이다. The present invention relates to an emergency lighting device in which the current is controlled after the battery is charged to prevent overcharging and the emergency lighting is blocked by the over-discharge prevention circuit part after the battery is discharged. More specifically, the battery is stabilized at a large capacity, for example, 5 A or more. The present invention relates to a battery overcharge / discharge control device for an emergency lighting lamp capable of charging and discharging in a state and capable of lighting a high brightness emergency lighting lamp for a long time.

보통 비상조명등은 고층건물, 관공서, 스포츠 경기장 및 콘서트장 등에서 화재발생 또는 정전 등의 긴급사태가 발생할 때, 이미 설치된 비상조명등 내부에 내장되어 있는 배터리를 이용하여 일정시간 동안 램프를 밝혀 출입 방향을 쉽게 찾을 수 있도록 되어 있다. 이를테면, 아파트나 빌딩의 계단이나 피난통로에 사용하는 비상조명등은 절전을 위하여 절전형 삼파장 전구를 사용하고 있지만, 비용이 많이 들어 대부분 센서부 자동 작동스위치를 사용하여 사람이 지나갈 때만 일정한 시간 동안 켜지게 하여 절전을 해왔다. In general, emergency lights illuminate the lamps for a certain period of time by using the battery built in the emergency lights installed in the high-rise buildings, government offices, sports stadiums and concert halls. You can find it. For example, emergency lighting used for stairs or evacuation passages in apartments or buildings uses energy-saving three-wavelength bulbs to save power, but it is expensive, and most of them use automatic sensor switches to turn on for only a certain time when people pass by. I have been power saving.

그러나, 센서등은 24시간 상시 점등되지 아니하여 전기절약이 되겠지만 점등 과 소등이 반복되어 비상시 대피에 지장을 초래할 우려가 있을 뿐 아니라 화재시에는 센서가 작동하더라도 연무(煙霧)에 의해 센서작동이 둔화되고 있다. 또 화재로 전기가 정전되었을 때 작동을 하지 않음으로 화재발생 등의 비상시에 계단이나 비상통로 등에서 사람들이 안전하게 대피할 수 있도록 비상조명등으로서의 역할을 충분히 해내지 못하여 화재시 많은 인명피해를 보고 있었다.However, although the sensor lamp is not turned on at all times for 24 hours, it will save electricity, but it may turn on and off repeatedly, which may cause the evacuation in case of an emergency, and in case of fire, the sensor operation may be slowed down by mist. It is becoming. In addition, when electricity was cut off due to a fire, many people were injured in the event of a fire because they did not fully play the role of emergency lighting to safely evacuate people on stairs or emergency passages in case of an emergency such as a fire.

이러한 실정을 감안하여 본 출원인은 정전시에 충전배터리로 조명등을 점등하는 비상조명등이 다각적으로 개발되어 있다. 즉, 화재로 인한 정전이나 기타 비상상황시에 안전하면서도 원활한 피난활동 및 지속적인 업무유지 등을 위하여 마련되는 비상조명등은 통상 비상용으로 충전배터리인 2 차 전지가 내장되어 있다. 따라서, 평상시에는 상용전원을 통해 점등되어 사용되다가 이러한 상용전원이 정전되는 경우에 전술한 2차 충전배터리로 대체 사용되는 비상전원으로 자동전환되어 비상 조명등이 점등될 수 있도록 설계되어 있다.In light of these circumstances, the present applicant has variously developed emergency lightings for lighting an illumination lamp with a rechargeable battery in case of power failure. That is, emergency lighting, which is provided for safe and smooth evacuation activities and continuous work in case of power failure or other emergency caused by fire, is usually equipped with a secondary battery which is a rechargeable battery for emergency use. Therefore, it is usually designed to be turned on through a commercial power source and then switched to an emergency power source to be used as an alternative to the above-described secondary charging battery when the commercial power source is out of power.

한편, 충전배터리인 2 차 전지가 양호하게 충전된 상태에서 화재로 인한 정전이나 기타 비상상황이 발생하여 정전되면, 충전배터리의 전원에 의해 비상조명등이 점등되어 비상시에 안전하고 원활한 피난활동을 할 수 있게 된다. 이러한 비상조명등은 점등되어 20 분 이상 지속되면 완전 방전되고, 48시간 이내에 충전되어야 하는 현재의 소방법을 만족하고 있기는 하지만, 화재등 대부분의 비상사태는 정전이 되어 비상조명등의 충전배터리가 방전되고 난 후 다시 충전되지 못하는 시간내에 일어나게 되므로 비상조명등은 점등되지 않아 무용지물이 되고 있는 것이다. On the other hand, if a power failure or other emergency occurs due to a fire while the rechargeable battery secondary battery is well charged, the emergency lighting is turned on by the power of the rechargeable battery, enabling safe and smooth evacuation in an emergency. Will be. Although these emergency lights are lit and fully discharged for more than 20 minutes, they meet current fire methods that must be recharged within 48 hours. However, most emergency lights, such as fires, have a power outage and discharge the rechargeable batteries such as emergency lights. After the recharge will occur within the time that can not be recharged emergency lighting is not useless.

이를테면, 한옥이나 낙후지역의 전기시설이 노후하여 정전이 빈번하게 일어 나는 곳에서는 1 차 정전으로 인한 비상조명등의 점등으로 충전배터리의 전원이 방전되고, 다시 충전배터리가 충전되지 못한 상태에서 재차 정전이 되는 경우가 발생하게 되고, 이 경우에는 충전배터리가 비상조명등을 점등시키지 못하게 되므로 비상상황시에 비상조명등의 기능을 발휘하지 못하게 되는 문제점이 야기된다.For example, in places where power failures occur frequently due to the aging of electric facilities in Hanok or underdeveloped areas, the power supply of the rechargeable battery is discharged by the lighting of emergency lighting caused by the first power failure, and the power failure again occurs when the rechargeable battery is not charged again. In this case, since the rechargeable battery does not turn on the emergency light, a problem arises in that it does not function as an emergency light in an emergency situation.

상기 충전배터리의 충전에는 12 ~ 15시간의 장시간이 소요되므로, 이 시간동안 상용전원을 충전배터리로 안정되게 공급되어야만 충전배터리가 양호하게 충전된다. 그러나, 비상조명등을 사용하는 업소나 가정 또는 공장마다 비상사태가 일어날 위험성이 상이할 뿐만 아니라, 비상사태로 인한 정전이 일어나는 빈도도 상이하여 비상사태가 자주 발생하거나 정전이 빈번하게 일어나는 곳에 설치된 비상조명등에 있어서는 비상조명등의 충전배터리가 충전되지 못한 상태에서 화재등 각종 비상사태의 발생이나 기타 요인으로 다시 정전이 되는 경우가 야기되어 비상조명등의 점등이 불가능하므로 충전배터리의 충전시간을 조절하여야 할 필요성이 있게 된다.Since the charging of the rechargeable battery takes a long time of 12 to 15 hours, the rechargeable battery is well charged only when the commercial power is stably supplied to the rechargeable battery during this time. However, not only are the risks of an emergency occurring in each business, home, or factory that uses emergency lighting, but also the frequency of power outages caused by the emergency is different, so emergency lights are installed where frequent emergency or blackouts occur. In the case of the emergency battery lamp is not charged, the occurrence of a power outage caused by a variety of emergencies such as fire or other factors, and the emergency lamp is impossible to turn on, so it is necessary to adjust the charging time of the rechargeable battery. Will be.

본 발명은 상기와 같은 제반 사정을 감안하여 발명한 것으로, 비상조명등을 점등하여야 할 비상상황에서 배터리의 과충방전에 따른 비상조명등의 라이트가 불안전하게 점등되지 않도록 사고를 미리 방지할 수 있는 비상조명등용 배터리 과충방전 제어장치를 제공하고자 함에 그 목적이 있다.The present invention has been invented in view of the above circumstances, and for emergency lighting which can prevent an accident in advance so that the lights of the emergency lighting lamp according to the overcharge and discharging of the battery do not unsafely light in an emergency situation where the emergency lighting lamp should be turned on.

이하, 본 발명의 바람직한 실시예를 예시도면에 의거하여 상세히 설명한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 은 본 발명의 실시예에 관한 비상조명등용 배터리 과충방전 제어장치를 설명하기 위한 개략블록도로서, 본 발명은 배터리(50)의 충전완료후 전류가 제어되어 과충전을 방지하고 배터리 방전종료후 과방전 방지회로부(30)에 의해 비상점등이 차단되는 비상조명등장치인 바, 이는 대용량으로 예컨데 5 A 이상의 배터리 (50)를 안정화상태로 충방전이 가능하고 정전시 고휘도 비상조명등의 라이트(60)를 장시간 점등시킬 수 있는 비상조명등용 배터리 과충방전 제어장치인 것이다. 1 is a schematic block diagram illustrating a battery overcharge and discharge control device for emergency lighting according to an embodiment of the present invention, the present invention is controlled after the completion of the charging of the battery 50 to prevent overcharge and after the end of battery discharge Emergency lighting device that the emergency light is cut off by the over-discharge prevention circuit part 30, which can be charged and discharged in a large capacity, for example, the battery 50 of 5 A or more in a stabilized state, the high-brightness emergency light (60) It is a battery overcharge / discharge control device for emergency lighting that can light up for a long time.

예비전원 축전지인 배터리(50)가 내장된 비상조명등장치는 뒷면커버를 분리하고 배터리단자(B+, B-)를 충전부(20)와 접속시킨 다음, 전원단자에 AC 220 V의 전원을 전원부(10)로 공급한다. 이때 비상조명등의 라이트(60)를 설치할 때는 벽면에 나사못을 설치하여 비상등 뒷면의 나사구멍에 맞춰서 고정시키고, 상기 라이트 (60)의 각도를 조절할 때에는 비상등의 헤드를 상하 좌우로 조절하여 사용할 수 있도록 되어 있다. Emergency lighting device with a built-in battery 50, a backup power storage battery, remove the rear cover and connect the battery terminals (B +, B-) with the charging unit 20, and then supply the AC 220V power to the power terminal (10) ). At this time, when installing the emergency light (60), the screw is installed on the wall surface to be fixed in accordance with the screw hole on the back of the emergency light, when adjusting the angle of the light (60) can be used to adjust the head of the emergency light up, down, left and right. have.

그리고, 상기 배터리(50)에는 과방전 방지회로부(30)와 단자(L-, L+)의 라이트(60)가 각각 연결되는 한편, 과충전제어부(40)에는 감시등의 적색램프(62)와 그린램프(64)가 각각 연결되게 된다. 이때, 상기 배터리(50)의 접속부위가 단락되거나 배터리(50)가 없을 경우에는 단자(L2)의 적색램프(62)가 점등되고, AC 전원이 연결될 때에는 단자(L1)의 그린램프(64)가 점등된다. In addition, the battery 50 is connected to the over-discharge prevention circuit unit 30 and the lights 60 of the terminals L- and L +, respectively, while the overcharge control unit 40 is connected to the red lamp 62 of the monitoring lamp and the green. The lamps 64 are connected to each other. At this time, when the connection part of the battery 50 is shorted or there is no battery 50, the red lamp 62 of the terminal L2 is turned on. When the AC power is connected, the green lamp 64 of the terminal L1 is turned on. Lights up.

상용전원이 연결되어 있을 경우에는 전원부(10)와 충전부(20)를 통해 배터리 (50)로 자동으로 충전이 된다. 배터리(50)의 충전이 완료될 때에는 과충전제어부 (40)에 의해 자동으로 배터리(50)에 과충전되지 않도록 전원이 제어된다. 그리고 정전시에는 고휘도의 라이트(60)가 점등되고 배터리(50)의 전원으로 고휘도의 비상조명등인 라이트(60)를 장시간 동안 점등시키게 되는 데, 이때 비상점등의 라이트 (60)가 종료되면 자동으로 과방전 방지회로부(30)가 작동하여 점등이 차단되며 적색램프(62)가 점등된다.

The over-discharge prevention circuit unit 30 operates to block the lighting and the red lamp 62 is turned on.

도 2 는 본 발명의 비상조명등용 배터리 과충방전 제어장치를 도시해 놓은 상세 회로도이다. Figure 2 is a detailed circuit diagram showing a battery overcharge and discharge control device for emergency lighting of the present invention.

상용전원 AC 220V가 휴즈(F1) 및 전원 푸쉬스위치(PS)를 통해 전원부(10)의 트랜스포머(PT57)에 공급되고, 2 차측으로 AC 16V가 유기되어 다이오드(D9 - D12)에 의해 양파 전류되어 직류 전원을 구하게 된다. 상기 전원부(10)에서 직류로 전환된 전원은 캐패시터(C6)에 의해 완전한 직류 전원으로 필터링되고, 충전부(20)의 싸이리스터(SCR)과 555 타이머 IC(A1) 및 릴레이접점(rl2)을 통해 배터리(50)에 자동으로 충전된다. 이때 라이트(60)는 점등되고 있지 않고, 저항(R4)를 통한 그린램프 (64)가 점등되어 외부에서 배터리(50)가 충전중임을 알 수 있다. Commercial power AC 220V is supplied to the transformer PT57 of the power supply unit 10 through the fuse (F1) and the power push switch (PS), AC 16V is induced to the secondary side and the onion current by the diode (D9-D12) DC power is obtained. The power converted to direct current from the power supply unit 10 is filtered by the capacitor C6 to the full direct current power, and through the thyristor SCR of the charging unit 20, the 555 timer IC A1, and the relay contact rl2. The battery 50 is automatically charged. At this time, the light 60 is not turned on, and the green lamp 64 through the resistor R4 is turned on, indicating that the battery 50 is being charged from the outside.

상기 충전부(20)에서의 555 타이머IC(A1)는 저항(R35, R34)사이에서 분기된 트랜지스터(T3, T4)와 더불어 제너다이오드(D16)에 의해 신호가 입력(⑤ - ⑧)됨에 따라, 출력단(③)으로 연결된 제너다이오드(D14)와 트랜지스터(T7)에 의해 싸이리스터(SCR)와 릴레이(RL1, RL2)가 동작되게 된다. 상기 싸이리스터(SCR)의 게이트에 의해 통전된 전원은 상기 555 타이머 IC(A1)와 제너다이오드(D15)에 의해 일정한 전원을 유지하여 릴레이(RL2)의 접점(rl2)과 휴즈(F2)를 통해 배터리(50)가 자동 충전되게 된다. As the 555 timer IC A1 in the charging unit 20 is input with the transistors T3 and T4 branched between the resistors R35 and R34 by the zener diode D16, the signals ⑤-⑧, The thyristor SCR and the relays RL1 and RL2 are operated by the zener diode D14 and the transistor T7 connected to the output terminal ③. Power supplied by the gate of the thyristor SCR is maintained by the 555 timer IC A1 and the zener diode D15 to maintain a constant power supply through the contact rl2 and the fuse F2 of the relay RL2. The battery 50 is automatically charged.

예비전원 배터리(50)의 충전중에 배터리 전원이 상승하면, 배터리(50)에 연결된 과충전제어부(40)에 있는 2개의 오피앰프(A2)와 제너다이오드(D17)에 의해 전류가 제어가 된다. 그리고, 정전시 라이트(60)가 점등되어 배터리 전압이 10.5V 미만이 되면 트랜지스터(Q1)가 턴오프되어 적색램프(62)가 점등된다. 상기 적색램프 (62)는 배터리 전압이 10.5V 이상이 되면 트랜지스터(Q1)가 턴온되므로 소등이 되게 된다. When the battery power rises while the preliminary power source battery 50 is being charged, the current is controlled by the two op amps A2 and the zener diode D17 in the overcharge control unit 40 connected to the battery 50. When the light 60 is turned on during the power failure and the battery voltage is lower than 10.5V, the transistor Q1 is turned off to turn on the red lamp 62. The red lamp 62 is turned off when the transistor Q1 is turned on when the battery voltage is 10.5V or more.

AC 전원이 정전 또는 비상시 전원이 차단되면 충전부(20)의 릴레이(RL2)가 작동되어 단자(L-, L+)의 라이트(60)가 예비전원 배터리(50)에 의해 장시간 점등되게 된다. 상기 라이트(60)의 점등이 종료되면, 과방전 방지회로부(30)의 제너다이오드(D18)와 턴오프의 트랜지스터(Q2)에 의해 릴레이(RL1)가 통전되면서, 릴레이접점(rl2)이 단락되어 배터리(50)와 라이트(60)의 접속이 단락되므로 과방전이 방지되게 된다. When the AC power is cut off in case of power failure or emergency, the relay RL2 of the charging unit 20 is operated so that the light 60 of the terminals L- and L + is turned on by the preliminary power battery 50 for a long time. When the light 60 is turned on, the relay contact rl2 is short-circuited while the relay RL1 is energized by the zener diode D18 of the over-discharge prevention circuit unit 30 and the turn-off transistor Q2. Since the connection of the battery 50 and the light 60 is short-circuited, overdischarge is prevented.

따라서, 상기 과방전 방지회로부(30)는 정전시 방전시간이 경과되어 배터리 전압이 10.5V 미만이 되면 제너다이오드(D18)와 트랜지스터(Q2)가 턴오프되므로 라이트(60)가 소등되면서 릴레이접점(rl2)에 의해 적색램프(62)는 점등된다. 이때 상기 트랜지스터(Q2)에 의해 다른 트랜지스터(T1, T6)를 통해 릴레이(RL2)가 동작되고 있다. Therefore, when the discharge time elapses during a power failure and the battery voltage becomes less than 10.5 V, the zener diode D18 and the transistor Q2 are turned off, so that the light 60 is turned off and the relay contact ( The red lamp 62 is turned on by rl2. At this time, the relay RL2 is operated by the transistor Q2 through the other transistors T1 and T6.

이상 설명한 바와 같이 본 발명은 상용전원이 연결되면 즉시 충전부(20)의 릴레이(RL2)를 통해 배터리(50)에 충전되고, 상기 배터리(50)의 충전이 완료되면 자동으로 과충전제어부(40)에 의해 자동으로 전류가 제어되어 과충전을 방지할 수 있다. 라이트(60)가 장시간 사용되어 배터리(50)의 방전이 종료되면 과방전 방지회로부(30)에 의해 자동으로 비상점등이 차단된다. As described above, when the commercial power is connected, the present invention is immediately charged to the battery 50 through the relay RL2 of the charging unit 20, and automatically charged to the overcharge control unit 40 when the charging of the battery 50 is completed. The current is automatically controlled by the overcharge can be prevented. When the light 60 is used for a long time and the discharge of the battery 50 is finished, the emergency light is automatically cut off by the over-discharge prevention circuit unit 30.
