이와같은 원방감시 시스템에 있어서, 사고가 발생했을시 신속하고 정확하게 사고가 처리될수 있어야 하는데, 사고발생을 청각적으로 알려주는 벨이 CRT에만 설치되어 있기 때문에 시스템이 한장소에 설치되어 시스템 운용요원, 사고처리 보수요원이 함께 근무하면 별 문제점이 없으나, 시스템이 여러장소에 분리, 설치되어 사고처리 보수 요원근무실에 사고기록 프린터가 설치되면 가청정보원이 없으므로 신속, 정확한 사고처리에 커다란 문제점을 야기시켰다.In such a remote surveillance system, when an accident occurs, it must be able to be handled quickly and accurately.Because an audible alarm bell is installed only in the CRT, the system is installed in one place, so that the system operation personnel, There is no problem when the accident handling repair workers work together, but when the system is separated and installed in several places, an accident record printer is installed in the office of the accident handling repair personnel, which causes a big problem for quick and accurate accident handling. .

따라서, 본 고안은 사고발생시 이를 시각 및 청각적으로 알수 있도록 하여 신속, 정확한 사고처리가 되도록 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention is designed to be able to quickly and accurately deal with accidents so that they can be seen visually and aurally when an accident occurs, which will be described in detail with reference to the accompanying drawings.

제2도는 본 고안의 원방감시 시스템의 블록도로서, 이에 도시한 바와같이 필드의 데이타 및 사고내용이 데이타 수집부(1)로 수집되어 메인시스템(2)에서 처리됨에 따라 CRT(5)에 표시되는 한편, 데이타기록 및 사고기록 프린터(3) (4)에 각기 기록되는 원방감시 시스템에 있어서, 상기 사고기록 프린터(4)에 전송되는 사고내용에 의해 경보발생부(6)로부터 경보가 발생되게 구성한다.2 is a block diagram of the remote monitoring system of the present invention. As shown in the drawing, data of a field and contents of an accident are collected by the data collection unit 1 and displayed on the CRT 5 as it is processed in the main system 2. On the other hand, in the remote monitoring system respectively recorded in the data recording and the accident recording printer (3) (4), an alarm is generated from the alarm generating section (6) by the contents of the accident transmitted to the accident recording printer (4) Configure.

제2도는 제1도 경보발생부(6)의 상세회로도로서, 이에 도시한 바와같이, 사고내용이 입력제한용 저항(R1), 소자보호용 커패시터(C1) 및 다이오드(D1)를 통해 트랜지스터(Q1)의 베이스에 인가되고, 이의 콜렉터가 트랜지스터(Q2)의 베이스측에 접속되어, 이의 콜렉터가 저항(R4,R5)을 통해 플립플롭(FF1),(FF2)의 클럭단자(CK1),(CK2)에 공통접속되며, 이 플립플롭(FF1),(FF2)의 세트단자(S1),(S2) 및 입력단자(D1),(D2)에는 전원단자(Vcc) 가 저항(R6),(R8)을 통해 공통접속됨과 아울러, 리세트단자(RS1),(RS2)에는 전원단자(Vcc)와 직렬접속되는 저항(R7),(R9) 및 커패시터(C2),(C3)의 접속점이 스위치(SW2),(SW3)를 각기 통해 접속되고, 상기 플립플롭(FF1)의 출력단자(Q1)는 부저구동용 트랜지스터(Q3)의 베이스에 접속되어 그의 에미터에 스위치(SW1)를 통해 부저(BZ1)가 접속되며, 상기 플립플롭(FF2)의 출력단자(Q2)는 발광다이오드(LED1)구동용 트랜지스터(Q4)의 베이스에 접속되어 구성된다.FIG. 2 is a detailed circuit diagram of the alarm generating unit 1 of FIG. 1, and as shown therein, the incident content is transmitted through the input limiting resistor R1, the device protection capacitor C1, and the diode D1. Is applied to the base of transistor Q2, and its collector is connected via the resistors R4 and R5 to the clock terminals CK1 and CK2 of the flip-flops FF1 and FF2. Is connected in common with the set terminals S1, S2 and input terminals D1 and D2 of the flip-flops FF1 and FF2, and the power supply terminals Vcc are resistors R6 and R8. In addition, the connection points of the resistors R7, R9, capacitors C2, and C3 connected in series with the power supply terminal Vcc are connected to the reset terminals RS1 and RS2. SW2 and SW3 are respectively connected, and the output terminal Q1 of the flip-flop FF1 is connected to the base of the buzzer driving transistor Q3, and the buzzer BZ1 is connected to the emitter through the switch SW1. ) Is connected to the flip-flop (FF2) Output terminal Q2 is connected to the base of the light emitting diode LED1 driving transistor Q4.

이와같이 구성되는 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.If described in detail the operation and effects of the subject innovation is configured as follows.

사고가 발생하면 메인시스템(2)으로부터 사고기록프린터(4) 및 경보발생부(6)로 사고내용이 전송되는데, 경보발생부(6)로 전송된 사고내용은 저항(R1), 소비보호용 커패시터(C1) 및 다이온드(D1)를 통해 트랜지스터(Q1)의 베이스에 인가되어 그 트랜지스터(Q1)를 온시키므로 그의 콜렉터에 저전위가 출력되어 트랜지스터(Q2)가 온된다.When an accident occurs, the contents of the accident are transmitted from the main system 2 to the accident record printer 4 and the alarm generator 6. The accident contents transmitted to the alarm generator 6 include a resistor R1 and a capacitor for consumer protection. It is applied to the base of the transistor Q1 through the C1 and the diode D1 to turn on the transistor Q1, so that a low potential is output to the collector thereof, and the transistor Q2 is turned on.

여기에서 저항(R1)값을 크게하여 입력을 제한하고, 이에 의해 사고기록 프린터(4)의 동작이상을 방지하며, 커패시터(C1)와 다이오드(D1)로 신호감지소자인 트랜지스터(Q1)를 보호한다.Here, the value of the resistor R1 is increased to limit the input, thereby preventing the operation of the accident recording printer 4 and protecting the transistor Q1, which is a signal sensing element, by the capacitor C1 and the diode D1. do.

한편, 상기 트랜지스터(Q2)의 도통에 의해 그의 콜렉터로부터 고전위신호가 출력되고, 이 고전위신호는 플립플롭(FF1),(FF2)의 클럭단자(CK1),(CK2)에 인가되어, 그 플립플롭(FF1),(FF2)이 클럭동작되며, 이에따라 그 플립플롭(FF1),(FF2)의 출력단자(Q1),(Q2)에 저전위신호가 출력되며, 이 저전위신호에 의해 트랜지스터(Q3),(Q4)가 온된다.On the other hand, due to the conduction of the transistor Q2, a high potential signal is output from the collector thereof, and the high potential signal is applied to the clock terminals CK1 and CK2 of the flip-flops FF1 and FF2. The flip-flops FF1 and FF2 are clocked, and accordingly the low potential signals are outputted to the output terminals Q1 and Q2 of the flip-flops FF1 and FF2. (Q3) and (Q4) are turned on.

이때 전원단자(Vcc)의 전원이 부저(BZ1). 스위치(SW1) 및 트랜지스터(Q3)를 통해 접지로 흐를 뿐만 아니라, 저항(R10), 발광다이오드(LED1) 및 트랜지스터(Q4)를 통해 접지로 흐르게 되어 부저(BZ1)의 구동으로 경보음이 발생하며, 발광다이오드(LED1)가 점등되어 경보표시가 된다.At this time, the power of the power terminal (Vcc) is the buzzer (BZ1). Not only flows to ground through the switch SW1 and the transistor Q3, but also flows to ground through the resistor R10, the light emitting diode LED1 and the transistor Q4, and an alarm sound is generated by the drive of the buzzer BZ1. The light-emitting diode LED1 lights up to give an alarm indication.

그리고, 경보표시만을 원하는 경우에는 스위치(SW1)를 개방시켜 부저(BZ1)의 구동을 중지시키고, 경보음 및 경보표시를 모두 필요로 하지 않을 시에는 스위치(SW2),(SW3)의 공통단자(C)를 고정단자(NC)에 접속시켜 플립플롭(FF1),(FF2)의 리세트단자(RS1),(RS2)에 전원단자(Vcc)의 고전위신호를 저항(R9)을 통해 인가시킴에 따라 그 플립플롭(FF1),(FF2)이 리세트 상태를 유지하게 되고, 이에따라 그 플립플롭(FF1),(FF2)의 출력단자(Q1),(Q2)에 고전위신호가 출력되어 트랜지스터(Q3),(Q4)가 오프상태를 유지하므로 경보음 발생용부저(BZ1) 및 경보표시용 발광다이오드(LED)는 구동되지 않게된다.If only the alarm display is desired, the switch SW1 is opened to stop the operation of the buzzer BZ1, and when neither the alarm sound nor the alarm display is required, the common terminals of the switches SW2 and SW3 are used. C) is connected to the fixed terminal NC to apply the high potential signal of the power supply terminal Vcc to the reset terminals RS1 and RS2 of the flip-flops FF1 and FF2 through the resistor R9. As a result, the flip-flops FF1 and FF2 maintain the reset state. Accordingly, a high-potential signal is output to the output terminals Q1 and Q2 of the flip-flops FF1 and FF2. Since (Q3) and (Q4) remain off, the alarm sound generating buzzer BZ1 and the alarm display light emitting diode LED are not driven.

이상의 상세한 설명과 같이 본 고안은 사고발생시 이를 청각 및 시각적으로 알려주어 즉각적이며 효과적으로 사고에 대처할수 있게 해주며, 작동을 중지시키기 전까지는 경보발생이 지속되므로 부재후 복귀했을때 사고발생을 쉽게 인지할수 있는 효과가 있다.As described in the above description, the present invention provides an audible and visual indication of an accident, so that it can be dealt with immediately and effectively.Also, alarms continue until the operation is stopped so that the accident can be easily recognized when returning from absence. It has an effect.
