본 발명은 적외선 통신 시스템에 관한 것으로, 특히 적외선 모듈에서 발생하는 적외선 데이터를, 광케이블을 통해 송수함으로써, 방향성 및 거리 제한을 해소시킬 수 있도록 한 적외선 통신 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared communication system, and more particularly, to an infrared communication system capable of eliminating directionality and distance limitation by transmitting infrared data generated from an infrared module through an optical cable.

도1은 종래 적외선 통신장치를 나타낸 것으로, 주(Master) 적외선 모듈(1) 및 종(Slave) 적외선 모듈(2)의 각각에 신호를 수신하는 수신단(11,21)과 적외선 신호를 송신하는 송신단(12,22)을 포함하여 구성되는데, 이와같은 적외선 통신장치의 송수신 동작을 설명한다.FIG. 1 shows a conventional infrared communication apparatus, which includes a receiving end 11 and 21 for receiving a signal and a transmitting end for transmitting an infrared signal to each of a master infrared module 1 and a slave infrared module 2. (12, 22), the operation of transmitting and receiving an infrared communication device will be described.

먼저, 주 적외선 모듈(1)의 송신단(12)에서 적외선 신호를 송신하면 종 적외 선 모듈(2)의 수신단(21)에서 적외선 신호를 수신한다.First, when the transmitting end 12 of the main infrared module 1 transmits an infrared signal, the receiving end 21 of the longitudinal infrared ray module 2 receives the infrared signal.

한편, 종 적외선 모듈(2)의 송신단(22)에서 적외선 신호를 송신하면 주 적외선 모듈(2)의 수신단(11)에서 적외선 신호를 수신한다.On the other hand, when the transmitting end 22 of the longitudinal infrared module 2 transmits an infrared signal, the receiving end 11 of the main infrared module 2 receives the infrared signal.

이때의 송수신은 한 시스템이 송신 중일 경우, 수신단은 디스에이블 되고 반대로, 수신 중일 경우 송신단이 디스에이블 되는 하프 듀플렉스(Half deplex) 방식으로 하는데, 이와 같은 송수신의 전환은 송신이나 수신이 일어난 후에 정해진 시간이 지나야 전환될 수 있다.In this case, the transmission and reception is a half duplex method in which a receiving end is disabled when a system is transmitting and the receiving end is disabled when receiving a system. Only after this can it be converted.

그러나, 제2도에 도시한 바와 같이, 종래의 적외선 통신장치는 송수신 가능거리가 1m이고 각도가 60°로 제한되어 있다.However, as shown in FIG. 2, the conventional infrared communication apparatus has a transmission / receivable distance of 1m and an angle of 60 °.

따라서, 적외선 통신을 하기 위해서는 주 적외선 모듈(1)과 종 적외선 모듈(2)의 거리와 각도를 맞추기 위해 시스템을 움직여야 하고, 두 개의 시스템이 프린터와 같은 한 디바이스를 공유하기 어려운 문제점이 있다.Therefore, in order to perform infrared communication, the system must be moved to match the distance and angle of the main infrared module 1 and the longitudinal infrared module 2, and two systems have a problem in that it is difficult to share a device such as a printer.

이와 같이, 종래의 적외선 통신장치는 송수신 가능거리 및 각도에 한계를 가지는 문제점이 있다.As such, the conventional infrared communication apparatus has a problem in that the transmission and reception distance and angle are limited.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 적외선 모듈에서 발생하는 적외선 데이터를, 광케이블을 통해 송수함으로써, 방향성 및 거리 제한을 해소시킬 수 있도록 한 적외선 통신 시스템을 제공함에 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an infrared communication system capable of eliminating directionality and distance limitation by transmitting infrared data generated from an infrared module through an optical cable. .

상기 네트워크 시스템은, 다수의 통신기기들이, 서로 적외선 데이터의 송수신 동작을 수행하는 경우에 그 데이터 송수신을 동기화하기 위한 제어로직을 포함한다.The network system includes a control logic for synchronizing data transmission and reception when a plurality of communication devices perform transmission and reception of infrared data with each other.

상기 제어로직은 각 통신기기의 적외선 모듈에서 발생하는 적외선데이터를 광케이블을 통해 입력받아 그 적외선 데이터가, 해당 통신기기로 전송되도록 전송경로의 스위칭을 제어한다.The control logic receives the infrared data generated from the infrared module of each communication device through the optical cable and controls the switching of the transmission path so that the infrared data is transmitted to the corresponding communication device.
