본 고안은 승강기의 비상등 구동회로에 관한 것으로서, 특히 정전시에 승강기 카(CAR)내부를 밝혀주는 비상등의 구동회로에 공급되는 밧데리의 비상등 구동 전력을 제어해줄수 있게 하므로서, 비상등의 구동 시간을 최대로 길게 할수 있게 한 것에 주안점을 둔 것이다.The present invention relates to the emergency light driving circuit of the elevator, and in particular, it is possible to control the emergency light driving power of the battery supplied to the driving circuit of the emergency light, which illuminates the inside of the elevator car during a power failure, thereby maximizing the driving time of the emergency light. The focus is on making it long.

종래에는 정전시에 전원이 차단되어 승강기 카 내부가 이루워지는 것을 방지하고자, 비상등을 점등시켜서 카 내부를 밝혀줄수 있게 하였는데 , 이는 제2도와 같이, AC입력전원 양단에 정전 검출용 릴레이(RY)와 정류회로(BD)를 연결하고, 이 정류회로(BD)의 직류전원 출력 단자에 충전회로(1)와, 충전용 밧데리(BT)를 병렬접속하고, 이 출력단자에 상기 정전용 검출 릴레이 집점(Y)을 거쳐 램프(LP)를 연결하여서된 것으로 이를 살펴보면 AC입력전원이 정상적으로 인가될때는 정전검출용 릴레이(RY)가 온되어 있으므로서 릴레이 접점(Y)이 오프되어 있기 때문에 비상등(LP)은 점등되게 않으며 충전용 밧데리(BT)에는 밧데리 충전회로(1)의 충전전류가 인가되어 계속 충전을 하게 된다.Conventionally, in order to prevent the power supply is cut off during the power failure, the interior of the elevator car is turned on so that the interior of the car can be illuminated by turning on the emergency light. As shown in FIG. 2, a relay for detecting power failure (RY) at both ends of the AC input power source. And rectifier circuit BD are connected, and charging circuit 1 and charging battery BT are connected in parallel to the DC power output terminal of the rectifier circuit BD, and the detection relay focuses on the output terminal. The lamp LP is connected through (Y). When the AC input power is normally applied, the relay contact (Y) is turned off while the relay (RY) is turned on so that the emergency light (LP) is turned on. Is not turned on, and the charging current of the battery charging circuit 1 is applied to the charging battery BT to continue charging.

그러나 AC입력전원이 정전이 되어 차단될시에는 정전 검출용 릴레이(RY)가 오프되어서 릴레이 접점(Y)을 온 시키므로서 충전용 밧데리(BT)에 충전되어 있는 전류가 릴레이 접점(Y)을 통해서 비상등(LP)에 방전전류가 흐르게 되므로서 비상등(LP)이 점등되게 되는 것이다.However, when the AC input power is cut off due to a power failure, the power failure detection relay RY is turned off to turn on the relay contact Y, so that the current charged in the charging battery BT is transferred through the relay contact Y. As the discharge current flows to the emergency light LP, the emergency light LP is turned on.

상기에서 계속 비상등(LP)이 점등되어 있으면 밧데리(BT)의 전압은 제5도와 같이 서서히 낮아지게 되고 밧데리(BT)의 충전용량에 해당하는 방전전류를 소모하게 되는 일정시간 TL후에는 밧데리(BT)의 전압이 급격히 저하되고 비상등(LP)이 소등되게 된다.If the emergency light LP is on continuously, the voltage of the battery BT is gradually lowered as shown in FIG. 5, and the battery BT is depleted after a certain time TL in which the discharge current corresponding to the charging capacity of the battery BT is consumed. ), The voltage drops rapidly and the emergency lamp LP goes out.

그러나 승강기가 내부의 비상등(LP)은 일정도로서 일정시간이상 점등시켜 줄수 있어야 하도록 규정되어 있다.However, the elevator is required to be able to light up the internal emergency light (LP) for a certain time.

그런데, 종래의 이상 점등회로에서는 비상등(LP)이 점등되는 초기에는 밧데리(BT)전압이 높으므로 많은 방전 전류가 흘러서 비상등(LP)이 규정치 이상의 조도를 낼수 있지만 시간이 지남에 따라 조도가 규정치 이하로 떨어지므로서, 비상등(LP)이 점등되는 시간이 단축되는 문제점을 가지고 있있다.However, in the conventional abnormal lighting circuit, since the battery BT voltage is high at the initial stage when the emergency light LP is turned on, many discharge currents flow, and the emergency light LP may produce illuminance above the specified value, but over time, the illuminance is below the prescribed value. By falling to the, the time that the emergency light (LP) is turned on has a problem that is shortened.

본 고안은 상기와 같은 종래의 문제점을 해결하고자, 초기에 비상등(LP)점등의 방전류를 필요이상 흐르지 않도록 제어하여 주므로서, 비상등이 규정된 일정 조도를 유지하면서 비상등이 점등될수 있게 할수 있으므로 비상등의 점등시간을 최대한으로 높힐수 있게 한 것에 주안점을 둔 것으로서 이를 첨부도면에 따라서 설명하면 다음과 같다.The present invention is designed to solve the above-mentioned problems in the above, by controlling the discharge flow of the emergency light (LP) lights so as not to flow more than necessary initially, so that the emergency light can be turned on while maintaining the predetermined constant illuminance of the emergency light The main point is to make the lighting time of the lamp as high as possible.

제1도와 같이 AC 입력전원 양단에 정전검출용 릴레이(RY)와 정류회로(BD)를 연결하고, 정류회로(BD)의 직류전원단자에 충진회로(1)와 충전용 밧데리(BT)를 병렬로 연결하고 밧데리(BT)의 출력단자에 릴레이 접점(Y)과 램프(LP)를 연결한다.As shown in FIG. 1, a power failure detection relay RY and a rectifier circuit BD are connected to both ends of an AC input power source, and a charging circuit 1 and a charging battery BT are connected in parallel to a DC power terminal of the rectifier circuit BD. Connect the relay contact (Y) and the lamp (LP) to the output terminal of the battery (BT).

그리고 상기 릴레이접점(Y)과 램프(LP)사이에 트랜지스터(TR)를 연결하여 이 트랜지스터(TR)의 베이스전류를 제어하기 위한 베이스 드라이브회로(2)를 연결한다. 상기 베이스 드라이브회로(2)는 제3도와 같이 공지의 삼각파 발생회로(3)와, 비교기(OP)를 구비하고, 정전용 검출 릴레이 접점(Y)을 통해 출력되는 전원단자(VBT)에 저항(R1)과 제너 다이오드(ZD)를 접속시킨 사이의 단자점(Vz)에 삼각파 발생회로(3)에 접속하며, 저항(R5, R6)을 거쳐 상기 비교기(OP)의 비반전단자(+)에 연결하고, 상기 전원단자(VBT)에서 저항(R2, R3)을 거쳐 비교기(OP)의 반전단자(-)에 접속하며, 삼각파 발생회로(3)의 출력단자(TQ)에서 저항(R8, R9)을 통해 비교기(OP)의 비반전단자(+)에 연결하여서 상기 저항(R2, R3)(R5, R6)(R8, R9) 사이의 단자점(Vf, Vb, Vt)에 집지저항(R4, R7, R10)을 연결한다.The transistor TR is connected between the relay contact Y and the lamp LP to connect the base drive circuit 2 for controlling the base current of the transistor TR. The base drive circuit 2 includes a known triangular wave generating circuit 3 and a comparator OP, as shown in FIG. 3, and a resistance to a power supply terminal V BT output through the detection relay contact Y of the electrostatic capacities . (R 1) and a Zener diode (ZD) and connected to the triangular wave generating circuit 3 to the terminal point (Vz) between which connecting, resistors (R 5, R 6), a non-inverting terminal of the comparator (OP) through the And the output terminal (TQ) of the triangular wave generator circuit (3), connected to the positive terminal, connected to the inverting terminal (-) of the comparator (OP) through the resistors (R 2 , R 3 ) at the power supply terminal (V BT ). ) between the resistors (R 8, R 9), a comparator (OP) hayeoseo connected to the non-inverting terminal (+), the resistance (R 2, R 3) of the (R 5, R 6) ( R 8, R 9) via at Connect the collecting resistors (R 4 , R 7 , R 10 ) to the terminal points (V f , V b , V t ) of.

그리고 상기 비교기(OP)의 출력에 트랜지스터(TR)의 베이스전류를 제어하는 트랜지스터(TR1)의 바이어스저항(R11)을 연결하여서 된 것이다.The bias resistor R 11 of the transistor TR 1 controlling the base current of the transistor TR is connected to the output of the comparator OP.

이와같은 구성으로 형성된 본 고안의 동작 및 작용 효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention formed in such a configuration as follows.

먼저 제3도에서 밧데리 전압(VBT)가 인가되면 삼각파 발생회로(3)가 구동되어서 그 출력(TQ)에는 삼각판출력이 나타나게 되고 저항(R6, R10)의 접속점 전압 Vt는 저항(R8,R10)에 의해 분압된 전압이 제4도(a)와 같이나타난다.First, when the battery voltage V BT is applied in FIG. 3, the triangular wave generating circuit 3 is driven so that the triangular plate output appears at the output TQ, and the connection point voltage V t of the resistors R 6 and R 10 is the resistance. The voltage divided by (R 8 , R 10 ) is shown in FIG. 4 (a).

또 밧데리 전압(VBT) 보다 조금 낮게 설정된 제너 다이오드(ZD)에 의한 제너 전압(VZD)에 의하여 저항(R5, R7)에 의해 분압된 일정 전압이 인가된다.A constant voltage divided by the resistors R 5 and R 7 is applied by the zener voltage V ZD by the zener diode ZD set slightly lower than the battery voltage V BT .

따라서, 비교기(OP)의 비반전(+)입덕에는 제4도 (b)와 같이 바이어스 전압 Vb만큼 비반전(+)쪽으로 쉬프트된 삼각파 전압 즉, Vt+Vb전압이 인가된다.Therefore, as shown in FIG. 4 (b), a triangular wave voltage shifted toward the non-inverting (+) side by the bias voltage V b , that is, the voltage V t + V b is applied to the non-inverting (+) side of the comparator OP.

한편, 저항(R2, R4)의 접속점 전압 Vf는 밧데리 전압(VBT)가 저항(R2, R4)에 의해 분압된 전압이 나타나며 이 전압이 비교기(OP)의 반전(-)측 입력에 인가되고 있다.Inverting the other hand, the resistance (R 2, R 4), the connection point voltage V f is the battery voltage (V BT), the resistance (R 2, R 4) of the voltage comparator (OP) appears and the voltage divided by the (-) It is being applied to the side input.

그러므로 비교기(OP)의 출력은 제4도(b)(c)에서 보듯이 Vt+Vb전압이 Vf전압보다 높은 부분에서만 하이가 출력되어서 일정한 듀티(duty)비를 가지는 구명파가 발생된다.Therefore, as shown in Fig. 4 (b) (c), the output of the comparator OP is high only when the V t + V b voltage is higher than the V f voltage to generate a life wave having a constant duty ratio. do.

그런데, 상기 Vf전압은 밧데리 전압(VBT)와 연동되어 변화하므로 제5도와 같이 밧데리 전압(VBT)가 서서히 낮아지면 Vf전압도 낮아진다.By the way, the V voltage, the lower the f also becomes lower as the fifth assist battery voltage (V BT) gradually changing voltage, V f in cooperation with the battery voltage (V BT).

그러면 제4도 (b)서와 같이 Vf가 낮아지면 Vt+Vb전압이 Vf보다 크게되는 시간이 커지므로 비교기(OP)의 출력이 구형파의 튜티 비는 거치게 되고 상기 Vf전압이 Vb전압 보다도 더 낮아지면 비교기(OP)의 출력은 계속 하이가 되게 된다.Then, as shown in FIG. 4 (b), when V f is lowered, the time taken for the V t + V b voltage to be greater than V f is increased, so that the output of the comparator OP goes through the duty ratio of the square wave and the V f voltage is the output of V b lower than the voltage when the comparator (OP) is continued to be high.

한편, 비교기(OP)의 출력이 하이상태인 동안은 트랜지스터(TR1)이 되므로 제1도에서 비상등 구동용 트랜지스터(TR)에는 베이스 전류가 흘러서 온 되므로 비상등(LP)은 점등되게 된다.On the other hand, since the transistor TR 1 is turned on while the output of the comparator OP is in a high state, since the base current flows on the emergency light driving transistor TR in FIG. 1, the emergency light LP is turned on.

따라서 상기 비교기(OP)의 출력 구형파의 듀티비에 따라서 비상등(LP)의 밝기를 조정할수가 잇다.Therefore, the brightness of the emergency light LP may be adjusted according to the duty ratio of the output square wave of the comparator OP.

그러므로 밧데리 전압이 높을때는 듀티비를 적게하여 일정한 조도가 되게 하고 밧데리 전압이 낮아지면 듀티비를 크게하여 역시 일정한 조도를 유지할수가 있다.Therefore, when the battery voltage is high, the duty ratio is reduced to a constant illuminance, and when the battery voltage is low, the duty ratio can be increased to maintain a constant illuminance.

상기와 같이 제1도에서 정진이 되어 정전 검출용 릴레이(RY)가 오프되면 충전되어 있던 밧데리 전압이 상기릴레이 접점(Y)을 거쳐서 비상등 구동 트랜지스터(TR)와 그의 베이스 드라이브 회로에 인가된다.As described above, when the power failure detecting relay RY is turned off in the case of FIG. 1, the charged battery voltage is applied to the emergency light driving transistor TR and its base drive circuit via the relay contact Y.

이때 방전초기의 밧데리 전압은 제5도에서와 같이 승강기 카내부를 일정 조도로 밝혀 줄수 있는 전압 VL보다 높으므로 제3도에서 비교기(OP)의 이반전(+)측 입력인 바이어스 전압 Vb를 적절하게 설정하여서 비교기(OP)의 구형파 출력의 듀티비를 승강기 카 내부의 밝기를 규정된 일정 조도 이상이 되도록 하여 두면 초기방전 전류가 과다히 흐르고 여기서 방전시간이 길어짐에 따라서 밧데리 전압 VBT가 낮아지면 그와 연동되어 비교기(OP)의 구형파 출력의 듀티비가 커지게 되므로 밧대리 전압 VBT가 낮아져도 승강기 카내부의 밝기를 일정조도로 계속 유지할수가 있다.At this time, the battery voltage of the initial discharge is higher than the voltage V L which can illuminate the inside of the elevator car with a constant illuminance as shown in FIG. 5, so that the bias voltage V b which is the input of the reverse side of the comparator OP in FIG. By properly setting the duty ratio of the square wave output of the comparator (OP) so that the brightness inside the elevator car is higher than the prescribed constant illuminance, the initial discharge current flows excessively, and as the discharge time becomes longer, the battery voltage V BT becomes When lowered, the duty ratio of the square wave output of the comparator OP increases, so that the brightness of the elevator car can be maintained at a constant level even when the battery voltage V BT decreases.

이와같이 밧데리 전압이 방전초기에는 높기 때문에 종래에는 승강기 내부의 조도가 필요이상으로 밝게 되며 따라서 소비전류도 커지게 되므로 밧데리의 전체 방전 시간이 줄어 들었다.Thus, since the battery voltage is high in the early stage of discharge, conventionally, the illuminance of the elevator becomes brighter than necessary, and thus the current consumption increases, thereby reducing the total discharge time of the battery.

그러나, 본 고안에 의하면 방전초기에 밧데리 전압이 높더라도 그것을 구형파로 단속적으로 인가하여서 규정된 승강기 내부의 조도를 유지할수 있는 전류만 소비하게 하므로서 밧데리의 방전시간을 최대화 할수가 있다.However, according to the present invention, even when the battery voltage is high in the early stage of discharge, it is intermittently applied as a square wave so as to consume only a current capable of maintaining the illuminance inside the specified elevator, thereby maximizing the discharge time of the battery.

따라서 밧데리의 전류용량을 줄일수 있게 되어 원가절감의 효과를 얻을수가 있다.Therefore, the current capacity of the battery can be reduced, resulting in cost reduction effect.
