본 발명은 광통신 전송장비에 있어서 가시가청 경보제어에 관한 것으로, 특히 시스템 경보가 발생하거나 유니트가 인출됐을 때 경보용 표시등과 부자를 제어하는 회로에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to visual audible alarm control in optical communications transmission equipment, and more particularly to circuitry for controlling the alarm indicator and rich when a system alarm occurs or the unit is withdrawn.

일반적으로 광통신 전송장치는 광신호를 이용하는 음성 및 영상정보를 전송하는 통신장치로서 광전송장비를 하나의 시스템으로 밀집 구성하여 각 광전송장비별 이상이 있을때 경보를 발생하게 하거나 광전송장비를 분리하였을 경우 가시가청 경보를 발생하게 된다.In general, an optical communication transmission device is a communication device that transmits voice and video information using an optical signal, and the optical transmission equipment is densely organized into a single system to generate an alarm when there is an abnormality for each optical transmission equipment or to visually hear when the optical transmission equipment is separated. It will generate an alarm.

광통신 전송장비의 가시가청 경보회로를 종래에 제1도와 같이 다수의 릴레이(RLY1-RLY14) 및 다이오드(D1-D8)로 구성되어 있으며 작동을 살펴보면 하기와 같다.The visual audible alarm circuit of the optical communication transmission device is conventionally composed of a plurality of relays (RLY1-RLY14) and diodes (D1-D8) as shown in FIG. 1 and will be described below.

평상시 입력라인(1-6)들은 플로팅(Floating)상태에 있게되며 모든 릴레이(RLY1-RLY14)는 작동하지 않는다. 먼저 입력라인(1)을 통해 시스템 경보제어 신호가 인가된 경우 라인(1)상의 입력전압은 0볼트(Volt)가 되어 다이오드(D1)을 통해 릴레이(RLY7)이 작동한다. 그러므로 단선상태에 있던 릴레이(RLY7)의 NO접점을 통해 램프(10)출력에 접지전위(GND)가 가해져 한쪽에 -48V가 인가되어져 있는 램프(10)가 점등된다. 이와함께 릴레이(RLY1)도 동작하여 릴레이(RLY8)의 접점(NC)을 통해 공급된 접지전위(GND)가 릴레이(RLY1)의 접점(NO)를 통해 릴레이(RLY14)를 동작시킨다. 이때 릴레이(RLY14)의 접점(NO)를 통하여 부저(Buzzer)에 접지전위(GND)가 가해져 부저가 울린다.Normally the input lines 1-6 are in floating state and all relays RLY1-RLY14 do not operate. First, when the system alarm control signal is applied through the input line 1, the input voltage on the line 1 becomes 0 Volt, and the relay RLY7 operates through the diode D1. Therefore, the ground potential GND is applied to the output of the lamp 10 through the NO contact of the relay RLY7 in the disconnected state, so that the lamp 10 to which -48V is applied to one side is turned on. In addition, the relay RLY1 also operates, so that the ground potential GND supplied through the contact NC of the relay RLY8 operates the relay RLY14 through the contact NO of the relay RLY1. At this time, the ground potential GND is applied to the buzzer through the contact NO of the relay RLY14, and the buzzer sounds.

상기 램프(10)와, 부저(20)가 작동중인 상태에서 부저 정지스위치(SW1)를 압압하면 다이오드(D7) 및 릴레이(RLY1)의 접점(NO)를 통해 접지전위(GND)가 공급되므로 릴레이(RLY8)가 동작케 되고, 이에따라 RLY8(NC) 접점이 차단되므로 릴레이(RLY1)의 NO 접점을 릴레이(RLY14) 코일에 공급되던 접지전위가 차단되어 릴레이(RLY14)가 동작을 멈추므로 릴레이(RLY14)의 NO접점을 통해 부저에 공급되던 접지전위가 차단되어 부저기 꺼진다.When pressing the buzzer stop switch SW1 while the lamp 10 and the buzzer 20 are in operation, the ground potential GND is supplied through the contact NO of the diode D7 and the relay RLY1. (RLY8) is operated, and accordingly, the RLY8 (NC) contact is cut off, so the ground potential that was supplied to the relay (RLY14) coil of the NO contact of the relay (RLY1) is cut off, and the relay (RLY14) stops the operation. The ground potential supplied to the buzzer is cut off through the NO contact of) and the buzzer turns off.

또한 릴레이(RLY8)의 접점(NO)과 다이오드(D13)를 통해 발광소자(LED)를 점등시킨다. 이 상태에서 다른 입력라인(2-5)에 경보 발생제어 신호가 발생되면 또다시 부저(20)가 울리게되며, 부저 정지스위치(SW1)를 압압하면 부저(20)는 작동을 중지하게 된다. 경보가 없으면 발광소자(LED) 및 램프(10)는 소등된다.In addition, the light emitting device LED is turned on through the contact NO of the relay RLY8 and the diode D13. In this state, when an alarm generation control signal is generated in another input line 2-5, the buzzer 20 sounds again, and when the buzzer stop switch SW1 is pressed, the buzzer 20 stops operating. If there is no alarm, the light emitting element LED and the lamp 10 are turned off.

상기와 같이 종래의 광전송장치에 가시가청 경보처리회로는 다수의 릴레이 및 다이오드를 사용하여 구성함으로 릴레이에 의해 부피가 큰 문제점이 있었다.As described above, the visible and audible alarm processing circuit in the conventional optical transmission device has a large volume problem due to the relay by using a plurality of relays and diodes.

따라서 본 발명의 목적은 광전송장치에 있어서 시스템의 이상상태 발생시나 시스템 분리시 정확하게 경보를 발생할 수 있고 회로를 간소화할 수 있는 광전송장치의 가시가청 경보처리회로를 제공함에 있다.Accordingly, an object of the present invention is to provide an audible and visual alarm processing circuit of an optical transmission device that can accurately generate an alarm and simplify a circuit when an abnormal state of a system occurs or a system is separated in an optical transmission device.

이하 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제2도는 본 발명의 회로도로서 시스템의 이상상태 및 전송장치의 분리를 가시표시하기 위한 램프(10)와, 시스템의 이상상태를 가칭표시하기 위한 부저(20)와, 다수의 전송장치의 이상상태나 착탈상태에 대한 경보발생 제어신호를 인입하기 위한 다수의 입력라인(1-6)들과, 상기 각 입력라인(1-6)을 통해 인입되는 경보발생 제어신호를 구동하기 위해 부논리합소자(51) 및 포토커플러(PC1)로 이루어진 제1구동수단과, 상기 각 입력라인(1-6)을 통해 인입되는 경보발생 제어신호에 의해 상기 부저(20)를 구동하기 위해 부논리합소자(52) 및 포토커플러(52)로 이루어진 제2구동수단과, 상기 각 입력라인(1-6)과 상기 제2구동수단 사이에 접속되어 각 입력라인(1-6)들의 경보발생 신호를 상기 제2구동수단으로 전송 또는 차단하기 위해 각각 하나의 반전소자(60-65) 및 논리곱소자(30-35)로 이루어진 제1-6전송수단과, 졍보 발생시 가청경보를 스위치(SW1)와, 경보발생시 가청경보가 중지되었음을 표시하기 위한 발광소자(LED)와, 상기 발광소자(LED)를 구동하기 위한 부논리합소자(53)와, 상기 각 입력라인(1-6)에 접속되어 상기 스위치(SW1)의 작동에 의해 상기 각 라인(1-6)상의 신호를 상기 각 전송수단에 인가하여 전송작동을 중지시키는 한편 상기 부논리합소자(70-75)로 이루어진 제1-6논리연산수단으로 구성된다.2 is a circuit diagram of the present invention, a lamp 10 for visually displaying an abnormal state of a system and separation of a transmission device, a buzzer 20 for tentatively displaying an abnormal state of a system, and an abnormal state of a plurality of transmission devices. Or a plurality of input lines 1-6 for inputting an alarm generation control signal for a detached state and a negative logic element for driving an alarm generation control signal introduced through each of the input lines 1-6. 51) and a negative logic element 52 for driving the buzzer 20 by means of a first driving means composed of a photo coupler PC1 and an alarm generation control signal introduced through the respective input lines 1-6. And a second driving means composed of a photo coupler 52 and the second driving means connected to each of the input lines 1-6 and the second driving means to generate an alarm signal of each of the input lines 1-6. One inverting element (60-65) and logical product each for transmission or interruption by means A first to sixth transmission means consisting of elements 30-35, a switch SW1 for audible alarm occurrence, a light emitting element LED for indicating that the audible alarm is stopped when an alarm occurs, and the light emitting element LED Connected to each of the input lines 1-6 and a signal on each of the lines 1-6 by the operation of the switch SW1 to the respective transmission means. And stops the transfer operation, and consists of 1-6 logic calculation means composed of the negative logic elements 70-75.

따라서 상술한 제2도를 참조하여 상세히 설명한다. 평상시 각 입력라인(1-6)상에 인입되는 경보발생 제어신호들은 로우논리상태이고 스위치(SW1)의 출력은 하이논리상태이다. 그러므로, 논리곱소자(36-41) B와 (30-35) A는 평상시 로우논리 상태이고, 논리합소자(70-75) B입력들은 모두 로우논리상태이다. 따라서 논리곱소자(36-41)의 출력들은 로우놀리상태이므로 논리합소자(70~75) 출력들도 로우논리상태이다. 또 논리곱소자(30-35)출력들도 로우논리상태이다.Therefore, it will be described in detail with reference to FIG. Normally the alarm generation control signals coming on each input line 1-6 are low logic state and the output of switch SW1 is high logic state. Therefore, the logical AND elements 36-41 B and (30-35) A are normally in a low logic state, and the B logic input elements 70-75 B inputs are all in a low logic state. Therefore, since the outputs of the logical AND elements 36-41 are low-noise states, the outputs of the logical OR elements 70 to 75 are also low logic states. The logic products 30-35 are also in a low logic state.

이때 발광소자(LED) 및 램프(10)와 부저(20)은 작동되지 않는다. 상기 상태에서 히이논리상태의 경보발생 신호가 지속적으로 인가되면 램프(10)과 부저(20)는 작동되어 점등되고 부저음을 발생한다. 상기 램프(10)와 부저(20)가 작동될 때 스위치(SW1)이 압압되면 부저(20)의 작동이 중지되고 발광소자(LED)가 점등된다.At this time, the light emitting device (LED) and the lamp 10 and the buzzer 20 are not operated. In this state, when the alarm generation signal of the high logic state is continuously applied, the lamp 10 and the buzzer 20 are operated to light and generate a buzzer sound. When the switch SW1 is pressed while the lamp 10 and the buzzer 20 are operated, the operation of the buzzer 20 is stopped and the light emitting device LED is turned on.

예를들어 하이논리상태의 경보발생 제어신호가 입력라인(1)에 인가되었다고 가정하면 부논리곱소자(51)의 출력은 로우논리상태가 되어 포토커플러(PC1)에 의해 램프(10)이 작동된다. 그리고 논리곱소자(30)은 하이논리상태의 경보발생 신호를 부논리곱소자(52)로 전송하고, 이때 부논리곱소자(52)는 출력이 로우논리상태가되어 포토커플러(PC2) 및 부저(20)를 작동시킨다.For example, assuming that a high logic alarm generation control signal is applied to the input line 1, the output of the negative logic element 51 becomes a low logic state so that the lamp 10 is operated by the photocoupler PC1. do. In addition, the logical multiplication device 30 transmits an alarm generation signal in a high logic state to the negative logical device 52, and at this time, the output of the negative logical device 52 becomes a low logic state so that the photocoupler PC2 and the buzzer are output. Activate (20).

상기 부저(20)이 작동된 상태에서 스위치(SW1)이 압압되면 이때 논리합소자(70)의 출력과 논리곱소자(36)의 출력은 하이논리상태가 된다. 그러면 논리곱소자(30)의 출력은 로우논리상태가 되어 부논리곱소자(52)의 출력이 하이논리상태로 천이하게 됨으로서 부저(20)의 작동은 정지된다.When the switch SW1 is pressed while the buzzer 20 is operated, the output of the logic sum element 70 and the output of the logic product element 36 are in a high logic state. Then, the output of the logical multiplication device 30 is in a low logic state, and the output of the negative logical element 52 transitions to a high logic state, so that the operation of the buzzer 20 is stopped.

한편 상기 논리합소자(70)의 하이논리상태의 출력에 의해 부논리곱소자(53)의 출력은 로우논리상태가 되어 발광소자(LED)가 점등되며 점등된 발광소자는 경보발생 신호가 로우논리상태로 천이할 때 소등된다.On the other hand, due to the output of the high logic state of the logic sum element 70, the output of the negative logic element 53 is in a low logic state, the light emitting element (LED) is turned on, the light emitting element is lit, the alarm signal is low logic state It is extinguished when it transitions to.

상기 상태를 가청경보 차단작동(Audible Alarm Cut Operation : 이하 ACO라함)이라고 한다.This state is called an audible alarm cut operation (hereinafter referred to as ACO).

하나의 경보발생 제어신호에 의해 ACO상태가 되었을 때 또다른 경보입력이 인가되면 다시 부저(20)이 울리고 스위치(SW1)에 의해 부저작동이 정지되며 램프(10)의 출력은 경보발생 신호가 있으면 항상 점등된다.When another alarm input is applied when ACO is activated by one alarm generation control signal, the buzzer 20 sounds again and the buzzer operation is stopped by the switch SW1, and the output of the lamp 10 indicates that there is an alarm signal. It always lights up.

상술한 바와같이 본 발명은 논리소자를 이용하여 정확한 가시가청경보를 발생할 수 있으며 회로의 수평연장 및 회로구성을 간소화할 수 있는 이점이 있다.As described above, the present invention can generate an accurate visual audible alarm using a logic element, and has the advantage of simplifying horizontal extension of a circuit and a circuit configuration.
