일반적으로 하나의 전송회선에 여러 개의 신호를 전송하는 멀티플렉스 신호는 아날로그 멀티플렉스 신호와 디지털 멀티플렉스 신호로 구분된다.In general, a multiplex signal for transmitting several signals on one transmission line is divided into an analog multiplex signal and a digital multiplex signal.
이 중 디지털 멀티플렉스(Digital Multiplex: 이하 DMX) 신호는 전자장치나 디스플레이 장치, 조명장치에 널리 사용되고 있고, 향후 그 사용 빈도가 많이 증가할 것으로 기대된다.Among them, digital multiplex (DMX) signals are widely used in electronic devices, display devices, and lighting devices, and are expected to increase in frequency in the future.
하나의 전송회선을 통해 전송된 DMX 신호를 여러 개의 신호로 분배하는 DMX 스플리터(Splitter)로 종래에는 보통의 구리선을 사용하는 바, 이 경우 DMX 스플리터는 장비 간에 절연(Isolation)을 위해 분기마다 별도의 전원이 필요하다.A DMX splitter that distributes DMX signals transmitted through one transmission line into several signals. Conventionally, ordinary copper wire is used. In this case, the DMX splitter is a separate branch for each device for isolation between devices. I need a power source.
또한, 상기한 바와 같이 분기마다 별도의 전원을 공급하더라도 장비와 장비를 연결하는 경우에 구리선을 심재로 하는 케이블의 용량(Capacitance)이 증가하여 5V의 구형파(square wave)를 사용하는 DMX 데이터의 변별력이 없어지고 데이터 에러가 발생한다.In addition, as described above, even when a separate power supply is provided for each branch, the capacity of a cable made of copper wire increases when the equipment is connected to the equipment, and the discrimination power of DMX data using a square wave of 5V is increased. Disappears and a data error occurs.
그리고 구리선 사용으로 발생하는 자기장 노이즈에 의해 DMX 신호가 망가져 DMX 통신에 악영향을 초래한다.In addition, magnetic field noise generated by the use of copper wires causes the DMX signal to be damaged, thereby adversely affecting DMX communication.
본 발명은 상술한 목적을 달성하기 위해 안출된 것으로서, 수신되는 DMX 데이터를 광데이터로 변환하고, 이 광데이터를 여러 개로 나누어 분배해서 전송함으로써 확실한 데이터를 각 장비에 공급하여 완벽한 DMX 통신 체계를 구축할 수 있는 디엠엑스-광 스플리터를 제공하는데 그 목적이 있다.The present invention has been made in order to achieve the above object, by converting the received DMX data into optical data, by dividing and transmitting the optical data into several pieces to supply reliable data to each equipment to build a complete DMX communication system An object of the present invention is to provide a DM-light splitter.

상기 DMX-광 컨버터를 통해 변환된 광데이터를 여러 개로 나누어 나누어진 각각의 광데이터를 광케이블을 통해 수신장치에 출력하되, 상기 수신장치에 출력되는 광데이터의 이득을 일정 이득으로 증폭하는 버퍼앰프와, 광케이블에 광을 방출하기 위한 광방출기가 구비되는 광 스플리터로 이루어지는 것을 특징으로 한다.A buffer amplifier for outputting each optical data divided into a plurality of optical data converted by the DMX-optical converter to a receiving device through an optical cable, and amplifying the gain of the optical data output to the receiving device with a predetermined gain; The optical cable is characterized by consisting of an optical splitter having a light emitter for emitting light.

도 1은 본 발명에 따른 DMX-광 스플리터의 블록도,1 is a block diagram of a DMX-optical splitter according to the present invention;
도 2는 도 1에 나타낸 스플리터의 외관 사시도.Fig. 2 is an external perspective view of the splitter shown in Fig. 1.
이하 본 발명의 실시예에 대하여 첨부된 도면을 참고로 그 구성 및 작용을 설명하기로 한다.Hereinafter, the configuration and operation of the embodiments of the present invention will be described with reference to the accompanying drawings.
먼저, 본 발명의 이해를 돕기 위해 DMX의 예로서 DMX512에 대해 설명하면, 상기 DMX512 프로토콜은 1986년 미국 극장 기술협회(USITT)에서 조명 콘솔 디머를 제어하기 위하여 만든 것으로서, 데이터 스트림(data stream) 형태로 데이터를 전송하는 방식으로 최대 512개의 채널에 8-BIT DATE의 정보를 전송할 수 있는 전송프로토콜로서 현재 극장, 경기장 등의 각종 조명 제어 시스템에 적용되고 있다.First, DMX512 is described as an example of DMX for the purpose of understanding the present invention. The DMX512 protocol was created by the US Theater Technical Association (USITT) in 1986 to control a lighting console dimmer, and form a data stream. It is a transmission protocol that can transmit information of 8-BIT DATE on up to 512 channels by transmitting data through a network. It is currently applied to various lighting control systems such as theaters and stadiums.
이 DMX512 프로토콜은 디지털 멀티플렉스 신호를 의미하는 것으로, 광원과 관련된 장비와 함께 사용되는 가장 공통적인 국제 표준규격이다.This DMX512 protocol stands for digital multiplex signal, the most common international standard used with light source-related equipment.
도 1은 본 발명에 따른 DMX-광 스플리터의 블록도이다.1 is a block diagram of a DMX-optical splitter according to the present invention.
도시된 바와 같이 DMX-광 스플리터(10)는 SMPS(11)와 DMX-광 컨버터(12)와 광 스플리터(13)를 포함하여 구성된다.As shown, the DMX optical splitter 10 includes an SMPS 11, a DMX optical converter 12, and an optical splitter 13.
SMPS(11)는 일반 상용교류 전원인 AC 전압을 DC 전압으로 바꾸어서 DMX-광 컨버터(12)에 공급한다.The SMPS 11 converts an AC voltage, which is a general commercial AC power supply, into a DC voltage and supplies it to the DMX-optical converter 12.
상기한 바와 같이 조명용 프로토콜인 DMX-512는 전기적인 신호이기 때문에 이 전기 신호를 노이즈 없이 확실하게 수신장치(20)에 전달하기 위해서는 광데이터로 변환시키는 것이 필요하고, DMX-광 컨버터(12)가 이 기능을 수행한다.As described above, since the lighting protocol DMX-512 is an electrical signal, it is necessary to convert the electrical signal into optical data in order to reliably transmit the electrical signal to the receiver 20 without noise, and the DMX-optical converter 12 Perform this function.
즉, DMX-광 컨버터(12)는 컴퓨터 등의 송신포트에서 보낸 DMX 신호를 수신해서 광데이터로 변환한 후 후단의 광 스플리터(13)에 송신한다.That is, the DMX optical converter 12 receives the DMX signal sent from a transmission port of a computer or the like, converts the optical signal into optical data, and then transmits the optical data to the optical splitter 13 at a later stage.
상기 광 스플리터(13)는 DMX-광 컨버터(12)를 통해 변환된 광데이터를 여러 개로(예를 들어 도면에서는 5개) 나눈 후 분배하여 각각의 광데이터를 광케이블을 통해 수신장치(20) 예를 들어 조명장치에 출력한다.The optical splitter 13 divides the optical data converted through the DMX-optical converter 12 into several pieces (for example, five in the drawing) and distributes them to each other to distribute each optical data through the optical cable. For example, output to the lighting device.
이때 수신장치(20)에 출력되는 광데이터의 손실을 억제하기 위해 광데이터의 이득을 일정 이득으로 증폭하는 버퍼앰프(14)와, 광케이블에 광을 방출하기 위한 광방출기(Optic Emitter: 15)가 분배된 개수만큼 구비된다.At this time, the buffer amplifier 14 for amplifying the gain of the optical data to a certain gain in order to suppress the loss of the optical data output to the receiver 20, and the optical emitter (Optic Emitter 15) for emitting light to the optical cable It is provided as many as the number distributed.
상기 광방출기(15)로는 레이저 광원이나 LED가 사용될 수 있으나, 본 발명에서는 발광 다이오드인 LED를 사용한다.A laser light source or an LED may be used as the light emitter 15, but in the present invention, an LED which is a light emitting diode is used.
한편, 수신장치(20)인 조명장치가 직접 광데이터를 수신할 수 없는 경우에 상기 조명장치에 DMX-광 컨버터(12)와 반대 기능을 수행하는 광-DMX 컨버터(21)가 구비된다.On the other hand, when the illuminator, which is the receiver 20, cannot directly receive the optical data, the illuminator is provided with an optical-DMX converter 21 which performs the function opposite to that of the DMX-optical converter 12.
즉, 송신포트(transmission-port)에서 보낸 DMX 신호를 광데이터로 바꾼 뒤 현장에 포설된 광케이블을 통해 광데이터 수신장치(20)에 전송된 경우 상기 수신장치(20)에서 직접 광데이터를 받아 들일 수 없다면 광-DMX 컨버터(21)를 이용해 광데이터를 다시 전기적 신호인 DMX 신호로 변환한다.That is, when the DMX signal sent from the transmission port (transmission-port) is converted to the optical data and then transmitted to the optical data receiving apparatus 20 through the optical cable installed in the field to receive the optical data directly from the receiving apparatus 20 If not, the optical-DMX converter 21 is used to convert the optical data back into an electrical signal DMX signal.
상기한 과정을 여러 번 반복해도 데이터에 영향이 없음으로 현장에 따른 설계가 자유롭다.Even if the above process is repeated several times, there is no influence on the data, and the design according to the site is free.
이상에서와 같은 본 발명에 의하면 DMX-광 스플리터(10)는 장비 간에 절연을 위해 분기마다 별도의 전원이 필요없고, 광케이블의 용량이 증가하지 않아 광데이터의 변별력이 유지되며 데이터 에러가 발생하지 않게 된다.According to the present invention as described above, the DMX-optical splitter 10 does not need a separate power supply for each branch to insulate between equipments, and the capacity of the optical cable does not increase so that the discriminating power of the optical data is maintained and data errors do not occur. do.
그리고 구리선을 사용하지 않고 광섬유를 사용하여 노이즈가 발생하지 않으므로 광데이터가 망가지지 않고 그대로 유지되어 완벽한 DMX 통신 체계를 구축할 수 있다.And since no noise is generated by using optical fiber without using copper wire, optical data can be kept intact and a perfect DMX communication system can be established.
도 2는 도 1에 나타낸 스플리터의 외관 사시도로서, 하나의 DMX 입력포트(16)를 통해 입력된 DMX 신호가 광데이터로 변환되고 5개의 광데이터로 나누어진 후 5개의 광 출력포트(17)에 분배되어 각 광 출력포트(17)에 연결되는 광케이블을 통해 외부로 출력된다.FIG. 2 is an external perspective view of the splitter shown in FIG. 1, in which a DMX signal input through one DMX input port 16 is converted into optical data, divided into five optical data, and then divided into five optical output ports 17. It is distributed and output to the outside through an optical cable connected to each optical output port 17.
