본 고안은 엘리베이터 제어반내에 제공되는 접점입력을 단시간 펄스로 만들어 공급코자 하는 단일펄스 발생회로에 관한 것이다.The present invention relates to a single pulse generating circuit for supplying a contact input provided in an elevator control panel into a short time pulse.
종래의 펄스 발생회로에 있어서는 제 1 도에 도시한 바와 같이 펄스발생 IC(10)의 입력단자(IN)에, 모우터 구동용 콘넥터 및 스위치에 의한 접점 입력을 인가시켜 그의 출력단자(OUT)에서 단일펄스를 얻어 승강기 제어반에 공급하도록 구성되어져 있으나, 이는 제 2 도에 나타낸 바와 같이 입력신호에 노이즈가 포함되면 그의 출력단자(OUT)에는 다수개의 펄스가 나타나게 되어 엘리베이터의 오동작을 초래하는 문제점이 있었다.In the conventional pulse generating circuit, as shown in FIG. 1, a contact input by a motor driving connector and a switch is applied to the input terminal IN of the pulse generating IC 10, and at its output terminal OUT. It is configured to obtain a single pulse and supply it to the elevator control panel. However, as shown in FIG. 2, when noise is included in the input signal, a number of pulses appear at the output terminal OUT thereof, which causes a malfunction of the elevator. .
본 고안은 이러한 점을 감안하여 안정된 엘리베이터 제어 동작을 수행하기 위하여 안출한 것으로, 이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to perform a stable elevator control operation in view of this point, it will be described in detail by the accompanying drawings as follows.
제 3 도에서와 같이 타이머 IC(100)의 콘트롤단자(CNTL1, CNTL2)에는 각각 전원노이즈 제거용 바이패스 콘덴서(C4, C5)를 연결하고,As shown in FIG. 3, bypass capacitors C 4 and C 5 for removing power supply noise are respectively connected to the control terminals CNTL 1 and CNTL 2 of the timer IC 100.
그의 디스에이블 단자(DIS1, DIS2)는 각각 드레쉬 홀드 단자(THR1, THR2), 저항(R2,R3) 및 콘덴서(C2,C3)를 연결하고,The disable terminals DIS 1 and DIS 2 connect the threshold hold terminals THR 1 and THR 2 , the resistors R 2 and R 3 , and the capacitors C 2 and C 3 , respectively.
상기 타이머 IC(100)의 출력단자(Q1)는 인버터(I1)를 통하여 그의 트리거 입력단자(TR2)에 연결하고,The output terminal Q 1 of the timer IC 100 is connected to its trigger input terminal TR 2 through an inverter I 1 ,
그의 트리거 입력단자(TR1)는 저항(R1)과 신호입력단자(A)에 연결하여 구성한다.The trigger input terminal TR 1 is connected to the resistor R 1 and the signal input terminal A.
미설명 부호 Q2는 출력단자이고, Vcc는 직류전원 단자이다.And reference numeral Q 2 is an output terminal, Vcc is a DC power supply terminal.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
제 3 도에서 초기에 신호입력단자(A)에 시간(to)에서 저전위 신호가 입력되면 타이머 IC(100)의 트리거 입력단자(TR1)에는 저전위가 인가되어 상기한 타이머 (100)를 트리거 시킴과 동시에, 저항(R2) 및 콘덴서(C2)에 의한 시정수동안 충전을 시작하여 상기 콘덴서(C2)가 충전되는 시간(to-t2)동안에는 그의 출력단다(Q1)에 고전위가 출력되며, 이 고전위 출력신호는 인버터(I1)를 통하여 트리거 입력단자(TR2)에 저전위로 변환되어 인가되므로 타이머 IC(100)는 트리거 되어 저항(R3), 콘덴서(C3)에 의한 시정수로서 그의 출력단자(Q2)에는 제 4 도에 도시한 바와 같이 시간(to-t1)동안 단일펄스가 출력되어 엘리베이터 제어반(도시 생략 함)에 가해지게 된다.In FIG. 3, when the low potential signal is initially input to the signal input terminal A at a time to, a low potential is applied to the trigger input terminal TR 1 of the timer IC 100 to supply the above timer 100. At the same time as triggering, charging starts during the time constant by the resistor R 2 and the capacitor C 2 and at its output stage Q 1 during the time to-t 2 during which the capacitor C 2 is charged. The high potential is output, and the high potential output signal is converted to the low potential and applied to the trigger input terminal TR 2 through the inverter I 1 , so that the timer IC 100 is triggered to generate a resistor R 3 and a capacitor C. As a time constant by 3 ), a single pulse is output to the output terminal Q 2 for a time to-t 1 as shown in FIG. 4 and applied to an elevator control panel (not shown).
한편, 제 3 도의 신호 입력단자(A)로 부터 인가되는 저전위 신호에 제 5 도 에 도시한 바와 같이 노이즈성분이 포함되어 있다 하더라도, 최초의 저전위가 인가되는 시간(to)에서 타이머(IC(100)는 트리거 상태가 되므로, 저항(R2), 및 콘덴서(C2)에 의한 충전 시정수시간(to-tx)동안은 타이머 IC(100)가 재트리거 되지 못하며, 또한 그의 출력단자(Q1)의 펄스 출력시간(to-tx)은 출력단자(Q2)의 펄스 출력시간(to-t1)보다 상당히 크게 설정되어 있으므로 타이머 IC(100)는 입력신호의 노이즈(Noise)유무에 관계없이 항상 일정하고도 정확한 단일 펄스를 출력하여 엘리베이터의 제어반에 공급하게 된다.On the other hand, even if the low-potential signal applied from the signal input terminal A of FIG. 3 includes the noise component as shown in FIG. 5, the timer IC at the time to which the first low potential is applied is to. Since 100 is in a triggered state, the timer IC 100 is not retriggered during the charge time constant time (to-tx) by the resistor R 2 and the capacitor C 2 , and the output terminal ( pulse output time (to-tx) of Q 1) is an output terminal (the timer IC (100) is the input signal noise (noise) or without it Q 2) of the pulse output time (to-t 1) than is set considerably larger Regardless, it always outputs a constant and accurate single pulse to the elevator control panel.
이와 같이 동작하는 본 고안은, 모우터 구동용 콘넥터 등의 온, 오프제어에 따른 노이즈의 영향을 전혀 받지않고, 항상 안정되고 일정한 단일 펄스를 엘리베이터의 제어반에 공급할 수가 있어, 엘리베이터에 있어서 운행상의 오동작을 방지하여 안전운행에 일익을 제공할 수 있는 유익한 고안인 것이다.The present invention operating as described above can always supply a stable and constant single pulse to the control panel of the elevator without being affected by the noise caused by the on / off control of the motor drive connector. It is a profitable design that can provide a benefit to safe operation by preventing accidents.
