본 발명은 액정표시장비의 원격제어시스템 및 제어방법에 관한 것으로서, 보다 상세하게는 장비의 외부 사무공간에서 원거리 작동기로 클린룸(cleaning room)내 검사장비에 접속하여 검사 작동, ECS(Equipment Control System) 제어 실시 및 로더(loader) 검사스테이지에 카메라를 설치하여 상시 모니터링하고, 장비내에는 기술자를 배치하여 운영하도록 한 액정표시장비의 원격제어시스템 및 제어방법에 관한 것이다.The present invention relates to a remote control system and a control method of a liquid crystal display device, and more particularly, an inspection operation by connecting to an inspection equipment in a cleaning room with a remote actuator in an external office space of the equipment, and an ECS (Equipment Control System). The present invention relates to a remote control system and a control method of a liquid crystal display device in which a camera is installed at a loader inspection stage and continuously monitored, and a technician is operated in the equipment.

현재 대부분의 기업에서는 자체적으로 잔산실 또는 이에 상응하는 컴퓨터 시스템 및 네트워크장비들을 자사의 전산장비의 숫자에 적합하게 운영하고 있으며, 이러한 전산장비들을 운영하는 운영자 또는 운영팀을 구성하고 있다.Currently, most companies operate their own residual room or equivalent computer system and network equipment in accordance with their number of computer equipment and form an operator or operation team that operates these computers.

종래 중앙집중 관리시스템 사용환경과는 달리 현재의 분산시스템 환경에서는 운영자들이 관리해야 할 전산장비의 숫자가 급격히 늘어나게 되는데, 일반적인 기업에서 꼭 필요로 하는 전산장비만 하더라도 기간 업무시스템, 메일서버, 웹서버, 파일서버, 데이터베이스서버, 라우터, 스위치, 무정전 전원장비 등으로 다수의 다양한 전산장비들을 필요로 한다.Unlike the existing centralized management system using environment, in the current distributed system environment, the number of computer equipments to be managed by the operator is rapidly increased. Even if the computer equipment is necessary for the general enterprise, the main business system, mail server, web server A variety of computing devices are required, including file servers, database servers, routers, switches, and uninterruptible power supplies.

최근에는 이러한 전산장비들의 돌발적인 사용중단사태를 막기 위하여 다양한 노력들이 기울어져 왔고, 그 결과로서 "NSM(network system management)" 이라는 기술이 제안되었다. NSM 기술은 운영자가 다수의 전산장비의 이상유무 확인 및 전산자원의 제어를 한자리에서 통합하여 관리할 수 잇게 해 준다.In recent years, various efforts have been made to prevent such accidental use of computer equipment, and as a result, a technology called "network system management" has been proposed. NSM technology enables operators to consolidate and manage multiple computer equipment checks and control of computing resources in one place.

이러한 통합관리시스템은 전산장비의 관리효율을 높였으며, 특히 전산장비의 운행이 중단되는 돌발사태를 미연에 방지하는데 큰 공헌을 하고 있다.This integrated management system has improved the management efficiency of the computer equipment, and in particular, is making a great contribution to preventing the sudden occurrence of the interruption of the operation of the computer equipment.

그러나, 이러한 종래의 NSM 관련기술과 이를 이용한 소프트웨어들은 운영자에게 전산장비를 관리하는 다양하고 편리한 기능을 제공하지만, 전산장비의 이상유 무 이상유무 확인 및 각종 전산장비를 제어관리하는 운영자가 항상 NSM 소프트 웨어의 관리자 화면을 모니터링하고 있지 않으면 안된다는 번거로움을 가지고 있다.However, while the related NSM-related technologies and the software using the same provide the operator with various and convenient functions for managing the computer equipment, the NSM software is always available for the operator who checks whether there is an abnormality of the computer equipment and controls and manages various computer equipment. It's a hassle that you have to monitor the manager's screen.

이러한 번거로움을 해소하기 위하여 일부 소프트웨어들은 전산장비에 이상이 발생하는 경우 전산우편 또는 무선호출을 통해서 운영자에게 통보해 주고 있지만, 전산장비의 이상을 통보 받은 운영자가 전산장비의 설치위치에서 벗어나 있는 경우 이상이 발생한 전산장비를 제어하지 못하고 있다.In order to solve this trouble, some softwares notify the operator through the computer mail or wireless call when the computer equipment has an error, but the operator who is notified of the computer equipment is out of the installation location of the computer equipment. Unable to control the computer equipment in which the error occurred.

이처럼, 장비에 이상 발생시 즉시 제어하지 못하는 경우, 전산장비뿐 아니라 24시간 가동이 필요한 생산장비의 경우에 있어서는 생산량 및 매출에 영향을 미치게 된다.As such, when an abnormality occurs in the equipment, it is not immediately possible to control the production and sales of not only the computerized equipment but also the production equipment that requires 24 hours of operation.

이에 종래의 관리시스템에는 전산장비 및 생산장비에 이상발생시 보다 빠른 대응을 위해 해당 전산장비 및 생산장비의 운영자에게 호출기와 같은 무선호출을 통해 이상발생을 알려 주는 기능이 부여되어 있다.Thus, the conventional management system is provided with a function of notifying the occurrence of an abnormality through a wireless call such as a pager to the operator of the computing equipment and the production equipment in order to respond quickly to the failure of the computing equipment and the production equipment.

그런데, 이러한 종래의 장비 관리시스템에 있어서는, 전술된 소프트 웨어를 이용한 장비의 이상발생확인 및 이상발생 제어를 해당 소프트웨어가 구동되는 장비를 이용해서만 가능하다는 번거로움을 가지고 있다.However, in such a conventional equipment management system, it is troublesome that the abnormal occurrence confirmation and abnormality control of the equipment using the above-described software can be performed only by using the equipment on which the corresponding software is driven.

이에 따라, 운영자가 퇴근을 하거나 업무상의 이유로 장비설치 우치를 벗어나는 경우에 발생할 수 있는 장비의 각종 이상 동작들을 확인할 수 없으며, 더우기 발생한 이상 동작을 신속하게 제어하여 장비를 다시 복구시키는 것이 용이하지 않다는 문제점을 가지고 있다.Accordingly, it is not possible to check various abnormal operations of the equipment which may occur when the operator leaves the office or leave the equipment installation for business reasons, and it is not easy to recover the equipment again by controlling the abnormal operation quickly.

도 2를 참조하면. 본 발명에 따른 액정표시장비의 원격제어시스템에서 PC 영상신호를 발생시키면 모니터 분배기를 통해 PC 영상신호가 분배되어져 국부적으로 RGB 방식으로 영상을 재현하게 된다. 또한, 이 모니터분배기를 통해 분배된 영상신호가 아날로그에서 디지털로 변환되어지고, 이렇게 변환되어진 디지털 영상신호는 광케이블로 전송되어지며, 이렇게 전송된 디지털 영상신호는 DVI 방식으로 원거리에서 영상을 재현하게 된다.Referring to FIG. 2. When the PC video signal is generated in the remote control system of the liquid crystal display device according to the present invention, the PC video signal is distributed through the monitor distributor to reproduce the image locally in the RGB method. In addition, the video signal distributed through this monitor splitter is converted from analog to digital, and the converted digital video signal is transmitted through an optical cable, and the digital video signal thus transmitted reproduces the image at a long distance using the DVI method. .

여기서, 상기 모니터분배기는 데이터서버(D-SUB)의 제1포트를 입력받아 제2포트의 데이터서버(D-SUB)로 출력한다. 이때, 상기 데이터서버입력은 PCD-서버로부터 이루어지고, 출력은 로컬 모니터(즉, 공장내 검사기모니터) 데이터서버로 이루어진다.Here, the monitor distributor receives the first port of the data server D-SUB and outputs it to the data server D-SUB of the second port. At this time, the data server input is from a PCD-server, and the output is from a local monitor (i.e. in-plant inspection monitor) data server.

또한, 검사화면 특성상 고화질의 해상도 및 영상 수준이 요구되는데, AD 전환기(converter)는 아날로그 신호를 디지털 신호로 전환한다.그리고, 300 m 이상 원거리의 로컬(local)과 원거리의 영상품질 동일화를 위해 광학케이블을 이용한다. In addition, due to the nature of the inspection screen, high resolution and image quality are required, and the AD converter converts analog signals into digital signals, and optical for equalizing local and remote image quality over 300m.

도 3을 참조하면, 본 발명에 따른 액정표시장비의 원격제어시스템에서 PC 영상신호가 발생하면, 모니터 분배기를 통해 PC 영상신호가 분배되어져 국부적으로 RGB 방식으로 영상을 재현하게 된다. 또한, 이 모니터분배기를 통해 분배된 영상신호를 KVM(TX)에 의해 아날로그로 UTP(Unshielded Twisted Pair cable)를 이용하여 적어도 약 300m 까지 송신되며, 이렇게 송신된 영상신호를 KVM(RX)를 통해 UTP(Unshielded Twisted Pair cable)를 이용하여 아날로그로 수신되고, 이렇게 수신된 아날로그 영상신호는 RGB 방식으로 원거리에 있는 영상을 재현하게 된다.Referring to FIG. 3, when the PC video signal is generated in the remote control system of the liquid crystal display device according to the present invention, the PC video signal is distributed through the monitor distributor to locally reproduce the image. In addition, the video signal distributed through this monitor distributor is transmitted by KVM (TX) to analog at least about 300m using UTP (Unshielded Twisted Pair cable), and the transmitted video signal is UTP through KVM (RX). It is received in analog using (Unshielded Twisted Pair cable), and the received analog video signal reproduces the remote video in the RGB method.

여기서, 상기 모니터분배기는 데이터서버(D-SUB)의 제1포트를 입력받아 제2포트의 데이터서버(D-SUB)로 출력한다. 이때, 상기 데이터서버입력은 PCD-서버로부터 이루어지고, 출력은 로컬 모니터(즉, 공장내 검사기모니터) 데이터서버로 이루어진다.Here, the monitor distributor receives the first port of the data server D-SUB and outputs it to the data server D-SUB of the second port. At this time, the data server input is from a PCD-server, and the output is from a local monitor (i.e. in-plant inspection monitor) data server.

300 m 이상의 원거리의 로컬(local)과 원거리(remote) 영상을 지원하는 KVM 적용하는데, KVM(TX)는 데이터서버의 포트를 통하여 영상신호를 받아 UTP(Unshielded Twisted Pair cable) 케이블을 통하여 원거리 전송이 가능하도록 하며, KVM(RX)는 KVM 확장기(TX)로부터 UTP(Unshielded Twisted Pair cable) 케이블을 통한 영상신호를 수신하여 데이터서버 포트로 출력한다.It applies KVM that supports local and remote video over 300m.
