위와 같이 구성된 본 발명의 작용 및 효과는 다음과 같다.Effects and effects of the present invention configured as described above are as follows.
먼저, 일반적으로 차량의 급제동시 후방차량에게 소정의 비상신호를 보내고자 하는 경우에 본 발명에 의한 차량용 비상등 자동 점멸회로를 적용하게 되면 우선, 상기 회로는 차량의 가속도 센서(1)에 전기적으로 연결되되 저항 RA및 저항 RB를 갖는 OP앰프(5)와, 저향 R1, 저항 R2, 콘덴서 C1및 콘덴서 C2를 갖는 타이머IC(6)와, 상기 OP앰프(5) 및 타이머IC(6)에 전기적으로 연결되는 제 1AND게이트(7)와, 상기 제 1AND게이트(7)에 전기적으로 연결되는 카운터IC(8)와, 상기 카운터IC(8)에 전기적으로 연결되는 제 2AND게이트(9)와, 상기 제 2AND게이트(9)에 전기적으로 연결되는 D-타입 플립플롭(10)과, 상기 D-타입 플립플롭(10)에 전기적으로 연결되는 트랜지스터(11) 및 릴레이(12)가 구비되게 된다.First, in general, when a vehicle emergency light auto flasher circuit according to the present invention is applied to send a predetermined emergency signal to a rear vehicle during sudden braking of the vehicle, the circuit is electrically connected to the acceleration sensor 1 of the vehicle. An op amp 5 having a resistor R A and a resistor R B , a timer IC 6 having a bottom R 1 , a resistor R 2 , a capacitor C 1, and a capacitor C 2 , and the OP amplifier 5 and a timer IC. A first AND gate 7 electrically connected to (6), a counter IC 8 electrically connected to the first AND gate 7, and a second AND gate electrically connected to the counter IC 8 ( 9), a D-type flip-flop 10 electrically connected to the second AND gate 9, and a transistor 11 and a relay 12 electrically connected to the D-type flip-flop 10. It will be provided.
즉, 상기 저항 RA및 저항 RB를 갖는 OP앰프(5)는 비교기로 사용되게 되는데 상기 OP앰프(5)의 반전 입력(-)쪽에는에 해당되는 전압 V가 걸리게 되며 비반전 입력(+)쪽에는 상기 가속도 센서(1)에서 나오는 출력전압이 걸게 된다.That is, the OP amplifier 5 having the resistor R A and the resistor R B is used as a comparator, but the inverting input (-) side of the OP amplifier 5 A voltage V corresponding to the voltage V is applied and an output voltage from the acceleration sensor 1 is applied to the non-inverting input (+).
또한, 상기 타이머IC(6)는 저항 R1, 저항 RC및 콘덴서 C1의 값에 의해 정해지는 시정수를 갖는 펄스열(Pulse Train)을 발생시키게 되는데 본 발명에 의한 상기 회로의 기준 클락(Clock)으로 사용되게 된다.In addition, the timer IC 6 generates a pulse train having a time constant determined by the values of the resistor R 1 , the resistor R C, and the capacitor C 1 . Will be used).
또한, 상기 카운터IC(8)은 입력 CK단자에 클락(Clock)이 하나씩 입력될 때마다 출력측 QA, QB, QC및 QD이 하나씩 업(Up) 혹은 다운(Down)되게 되며 상기 카운터IC(8)의 클리어 단자(CLR)는 차량의 브레이크등 스위치(4)에 연결되어 있다.In addition, the counter IC 8 outputs Q A , Q B , Q C, and Q D up or down one by one every time a clock is input to the input CK terminal. The clear terminal CLR of the IC 8 is connected to the brake light switch 4 of the vehicle.
또한, 상기 D-타입 플립플롭(10)의 입력 CK 단자는 상기 제 2AND게이트(9)의 출력에 연결되어 있고 클리어 단자(CLR)는 상기 브레이크 스위치(4)에 연결되어 있다.In addition, the input CK terminal of the D-type flip-flop 10 is connected to the output of the second AND gate 9 and the clear terminal CLR is connected to the brake switch 4.
따라서, 차량으로 고속 주행중 급제동을 걸게 되면 차량의 가속도 센서(1)는 차량의 가속도를 감지하여 로그(Log)함수에 비례되는 출력전압을 갖게 되는데 상기 출력전압이 상기 OP앰프(5)의 저항 RA및 RB으로 이루어진 전압 분배기의 전압 이상이 되게 되면 상기 OP앰프(5)의 출력은 High가 되게 된다.Therefore, when sudden braking is applied during high-speed driving in the vehicle, the acceleration sensor 1 of the vehicle detects the acceleration of the vehicle and has an output voltage proportional to a log function, wherein the output voltage is the resistance R of the OP amplifier 5. When the voltage of the voltage divider consisting of A and R B is greater than or equal to, the output of the OP amplifier 5 becomes high.
또한, 상기 OP앰프(5)측 출력과 상기 타이머IC(6)측 출력이 제 1AND게이트(7)를 지나게 되므로 상기 카운터IC(8)로 입력되는 클락신호는 상기 OP앰프(5)의 출력이 High가 될 경우에만 입력되게 된다. 즉, 차량의 급제동이 걸리게 되는 경우에만 입력되게 된다.In addition, since the output of the OP amp 5 side and the output of the timer IC 6 pass through the first AND gate 7, the clock signal input to the counter IC 8 is the output of the OP amp 5. It will be input only when it becomes High. That is, it is input only when the braking of the vehicle is applied.
또한, 상기 카운터IC(8)는 4비트(Bit) 카운터에서 클락 입력이 하나 있을 때마다 업(Up) 카운트되게 되는 그에 따라 클락이 15개 입력되면 상기 QA, QB, QC및 QD가 모두 High가 되고 이 신호들에 상기 제 2AND게이트(9)의 출력신호가 High로 되게 된다.In addition, the counter IC (8) is a 4-bit (Bit) When at each time one clock input counter-up (Up) accordingly is to be counted the clock input 15 wherein Q A, Q B, Q C and Q D Are both high, and the output signal of the second AND gate 9 is high.
또한, 상기 제 2AND게이트(9)의 출력신호가 High로 되게 됨에 따라 상기 D-타입 플립플롭(10)이 Set되게 되며 그에 따라서 상기 트랜지스터(11)가 온(ON)되게 됨과 더불어 상기 릴레이(12)가 동작되어 차량의 비상등 스위치(2)가 켜지게 된다.In addition, as the output signal of the second AND gate 9 becomes high, the D-type flip-flop 10 is set, and accordingly, the transistor 11 is turned on and the relay 12 is turned on. ) Is operated to turn on the emergency light switch 2 of the vehicle.
또한, 운전자가 차량의 브레이크 페달을 놓게 되면 상기 카운터IC(8) 및 D-타입 플립플롭(10)이 클리어(Clear)되게 되므로 상기 카운터IC(8)의 출력 QA, QB, QC및 QD는 0으로 되며 D-타입 플립플롭(10)의 출력 Q도 0으로 클리어되게 된다.In addition, when the driver releases the brake pedal of the vehicle, the counter IC 8 and the D-type flip-flop 10 are cleared, so that the outputs Q A , Q B , Q C and Q D becomes zero and the output Q of the D-type flip-flop 10 is also cleared to zero.
참고적으로, 제2도는 상기 타이머IC의 출력 클락신호에 따른 OP앰프, 제 1AND게이트, 제 2AND게이트 및 상기 D-타입 플립플롭의 출력을 나타낸 타임 다이아그램 차트(Time Diagram Chart)이다.For reference, FIG. 2 is a time diagram chart showing outputs of the OP amplifier, the first AND gate, the second AND gate, and the D-type flip-flop according to the output clock signal of the timer IC.
위와같이, 본 발명에 의한 차량용 비상등 자동 점멸회로는 차량으로 고속 중행중 급제동을 걸게 되면 차량의 가속도 센서(1)가 일정전압 이상의 출력전압을 갖게 되는데 이때, 상기 출력전압이 상기 비상등 자동 저멸회로에 인가되게 되면 자동으로 차량의 비상등(3)이 점멸하게 함으로써 차량의 고속 주행중 급제동을 걸 때 발생될 수 있는 돌발적인 사고를 미연에 방지할 수 있게 되는 효과가 있다.As described above, the vehicle emergency light automatic flashing circuit according to the present invention has an output voltage of a certain voltage or more when the acceleration sensor 1 of the vehicle is subjected to rapid braking during a high-speed running in the vehicle, wherein the output voltage is applied to the emergency light automatic deactivation circuit. When applied, the emergency light 3 of the vehicle is automatically blinked, thereby preventing accidental accidents that may occur when sudden braking is performed during high-speed driving of the vehicle.
