Description

광케이블 선번 관리 시스템의 무선통신모듈 및 그 제어방법Wireless communication module of optical cable number management system and its control method
본 발명은 광케이블 선번 관리 시스템의 무선통신모듈 및 그 제어방법에 관한 것으로, 더 구체적으로는 광케이블의 접속함체 내부의 환경정보 및 광케이블 선번정보를 외부 단말기로 무선전송하는 무선통신모듈 및 무선통신모듈의 제어방법에 관한 것이다.The present invention relates to a wireless communication module of the optical cable number management system and a control method thereof, and more particularly, to a wireless communication module and a wireless communication module for wirelessly transmitting environmental information and optical cable number information inside an optical cable connection enclosure to an external terminal. It relates to a control method.
일반적으로, 통신 및 방송 가입자들은 ADSL(Asymmetric Digital Subscriber Line), VDSL(Very High Bit-Rate Digital Subscriber Line), Ethernet LAN(Local Area Network), 케이블 모뎀(cable modem) 등을 통해 초고속 인터넷 등의 데이터 서비스를 이용하고 있으며, HFC(Hybrid Fiber Coaxial)를 기반으로 한 케이블 방송과 위성방송을 이용하여 방송 서비스를 이용하고 있었다.In general, telecommunications and broadcast subscribers use data such as high-speed Internet through Asymmetric Digital Subscriber Line (ADSL), Very High Bit-Rate Digital Subscriber Line (VDSL), Ethernet Local Area Network (LAN), and cable modem. The service is being used, and cable service and satellite broadcasting based on HFC (Hybrid Fiber Coaxial) are used for broadcasting service.
근래에는, 가입자에게 고속, 대용량의 통신, 방송 서비스를 제공하기 위해서는 각 가입자 댁내까지 광케이블을 연결한 FTTH(Fiber To The Home) 시스템의 보급화가 빠른 속도로 이루어지고 있다.In recent years, in order to provide high-speed, high-capacity communication and broadcasting services to subscribers, the popularity of FTTH (Fiber To The Home) systems connecting optical cables to subscribers' homes has been rapidly increasing.
광케이블은 광신호를 전송하는 케이블로서, 전기신호를 전송하는 일반적인 동축 케이블과는 달리 많은 양의 정보를 손실 없이 신속하게 전송할 수 있어 최근 정보화 시대의 도래에 따라 상기 광케이블의 수요가 급속히 확산되고 있으며, 광케이블의 관련 기술 개발도 꾸준하게 이루어지고 있다.Optical cable is a cable for transmitting optical signals, unlike general coaxial cables for transmitting electrical signals, it is possible to quickly transmit a large amount of information without loss, the demand of the optical cable is rapidly spread in accordance with the recent information age. Related technology development of optical cable is also steadily being made.
이와 같은 광케이블은 설치 길이에 따라 중간 중간을 연결해야 하는 데, 이때 상기 광케이블은 별도의 접속 단자를 이용하여 연결되며 광케이블로부터 필요한 부분만큼 분기(分枝)가 이루어질 경우에도 광케이블 접속 단자를 이용하여 광케이블을 분기시키게 된다.Such optical cable should be connected to the middle of the middle according to the installation length, wherein the optical cable is connected by using a separate connection terminal, even if the branch is made as much as necessary from the optical cable using the optical cable connection terminal Will diverge.
이러한 광케이블을 이용한 통신에 있어서, 각 광섬유는 여러 개로 분기하여 각각 가입자를 수용할 수 있는데, 일 예로써 하나의 광섬유를 통과하는 신호는 광 수동소자(광 스플리터 또는 파장 분리기)를 이용하여 다수의 광신호로 분배될 수 있다. In the communication using such an optical cable, each optical fiber can be divided into several to accommodate subscribers. For example, a signal passing through one optical fiber is provided by using an optical passive element (optical splitter or wavelength splitter). Can be distributed as a signal.
따라서 광섬유를 다수 포함하는 광케이블을 댁내 가입자가 위치한 근처까지 연결하고 해당 광케이블의 광섬유와 댁내 가입자의 단말기와 연결하도록 하기 위한 광케이블 접속 분배함이 제시된 바 있다.Therefore, an optical cable connection distribution box has been proposed for connecting an optical cable including a plurality of optical fibers to a neighborhood of a home subscriber and connecting the optical fiber of the optical cable to a terminal of the indoor subscriber.
*즉, 광케이블 접속 분배함은 광케이블이 지나가는 곳 중간에 설치되어 인입 광케이블로부터 추출된 광섬유와 댁내 가입자의 개통용 케이블의 결합이 용이하도록 하는 한편, 인출 광케이블의 각 광섬유와의 결합이 용이하도록 하는 기능을 수행한다.* In other words, the optical cable connection distribution box is installed in the middle of the optical cable passing place to facilitate the coupling of the optical fiber extracted from the incoming optical cable with the opening cable of the subscriber in the house, and the coupling of the optical fiber with the respective optical fibers. Do this.
이러한 광케이블 접속 분배함을 통해 이종 네트워크간의 상호 접속이 이루어질 수 있는데, 이종 네트워크간을 상호접속함에 있어 무엇보다 중요한 것이 인입 및 인출되는 광섬유의 선번의 관리라 할 수 있다.Interconnection between heterogeneous networks can be achieved through the distribution distribution of the optical cables. The most important thing in interconnecting heterogeneous networks is management of the number of incoming and outgoing optical fibers.
그러나 일반적인 광케이블 접속 분배함에서는 인입 및 인출되는 광섬유의 선번 관리가 작업자의 수작업에 의해, 예를 들면 작업자가 지면에 인입 및 인출 선로의 선번 기입을 통해 관리하기 때문에 비효율적일 뿐만 아니라, 광케이블 접속 분배함 관리자 입장에서는 사람에 따라 광섬유의 선번 식별이 용이하지 않은 문제점이 있었다.However, in general optical cable connection distribution box, not only is it inefficient because the management of the number of incoming and outgoing optical fibers is managed by the operator's manual work, for example, the operator writes the number of incoming and outgoing lines on the ground. From the manager's point of view, there was a problem that the identification of the line number of the optical fiber was not easy.
이로 인해, 원격지에서 광케이블 접속함체의 광섬유 선번 데이터 및 접속함체 내부의 환경 데이터를 모니터링하여 관리할 수 있는 광케이블 선번 관리 시스템이 제시되었다. For this reason, an optical cable number management system that can monitor and manage the optical fiber number data of the optical cable junction box and the environmental data inside the junction box at a remote location has been proposed.
한편, 광케이블 접속부를 수용하며 선번 데이터 등을 저장하는 광케이블 접속함체는 전신주에 설치되거나 지중에 단독으로 매설되기 때문에, 선번 데이터 등을 저장하거나 무선통신을 위해 요구되는 구동전원을 위해 소형 배터리가 사용되고 있다.On the other hand, since the optical cable connection housing for accommodating the optical cable connection portion and storing the serial number data is installed in the telephone pole or embedded in the ground alone, a small battery is used for the driving power required for storing the serial number data or for wireless communication. .
그러나, 이러한 소형 배터리는 자체 방전되는 특성을 가지고 있어 배터리 수명을 증가시키는 기술이 요구되고 있다.However, these small batteries have a self-discharging characteristic, and thus, a technology for increasing battery life is required.
본 발명의 목적은 광케이블 접속함체 내부에 설치되는 무선통신모듈의 소비 전력량을 저감시킬 수 있는 광케이블 선번 관리 시스템의 무선통신모듈 및 그 제어방법을 제공하는 것이다.An object of the present invention is to provide a wireless communication module and a control method of the optical cable number management system that can reduce the power consumption of the wireless communication module installed in the optical cable connection enclosure.
상술한 본 발명의 목적을 달성하기 위하여, 본 발명은 광케이블 접속부를 수용하며 상기 광케이블의 광섬유 선번 데이터 및 주변 환경 데이터를 저장 관리하는 광케이블 접속함체와, 상기 광케이블 접속함체와 무선통신하는 외부 단말기와, 상기 광케이블 접속함체를 원격 제어하는 중앙관제서버를 포함하는 광케이블 선번 관리 시스템에 있어서, 상기 광케이블 접속함체는 상기 외부 단말기로부터 무선 전력 전송된 무선 전력에 의해 무선통신이 개시되는 무선통신모듈을 구비하는 광케이블 선번 관리 시스템의 무선통신모듈을 제공할 수 있다.In order to achieve the above object of the present invention, the present invention provides an optical cable connection housing for storing and managing the optical fiber number data and environmental data of the optical cable and the external terminal for wireless communication with the optical cable connection enclosure; An optical cable number management system comprising a central control server for remotely controlling the optical cable connection enclosure, wherein the optical cable connection enclosure includes an optical cable including a wireless communication module to start wireless communication by wireless power transmitted from the external terminal. It is possible to provide a wireless communication module of a number management system.
여기서 상기 무선통신모듈은, 상기 광케이블 접속함체의 전원부의 전원을 비소모하는 대기모드와 상기 외부 단말기와 무선 데이터 통신을 수행하는 구동모드 사이에서 작동하며, 상기 외부 단말기로부터 전송된 상기 무선 전력에 의해 상기 대기모드에서 상기 구동모드로 모드가 전환될 수 있다.Herein, the wireless communication module operates between a standby mode for consuming no power of the power supply unit of the optical cable connection enclosure and a driving mode for performing wireless data communication with the external terminal, and by the wireless power transmitted from the external terminal. The mode may be switched from the standby mode to the driving mode.
