수용가에는 전기 수도 가스의 원격검침, 방재 및 보안정보를 처리하는 SIU(System interface unit)를 별도로 설치하지 아니하고 전력량계에 내장(또는 탈착식으로 결합하여 봉인)하여Customers do not have to install a SIU (System Interface Unit) for remote metering, disaster prevention, and security information of electric water gas.
전력량계와 함께 수도 가스계량기를 검침하고I read the water gas meter together with the electricity meter
유해가스 검출경보 등 방재 및 보안시스템으로도 활용하는 것이며 전력량계의 SIU가 전기 수도 가스의 검침작업 중이라도 가스누설 등 방재, 보안정보가 있으면 인터럽트 온(Interrupt on)하여 검침작업을 중단하고 방재, 보안업무를 먼저 수행한다.It is also used as a disaster prevention and security system such as detection of harmful gas.If the SIU of the electricity meter reads electricity water gas while there is disaster prevention or security information such as gas leakage, it interrupts the meter reading operation by interrupting the disaster prevention and security work. First.
또 변압기의 2차 선로에 부착하여 변압기의 부하감시와 원격검침을 하는 데이터 컨센트레이터(Data concentrator, 에어리어 컨트롤러 및 섹터 컨트롤러)에 정전보상회로(백업 전원 포함)부와 정전검출부를 두어 정전 유무를 감시하고 CDMA가 꺼져 있는지를 이동통신회사나 검침센터에서 직접 또는 이동통신회사에서 전담하여 점검하며In addition, a power failure compensation circuit (including backup power supply) and a power failure detection unit are installed in a data concentrator (data concentrator, area controller, and sector controller) that attaches to the secondary line of the transformer to monitor and load the transformer. Check whether the CDMA is turned off directly at the carrier or meter center or at the carrier.

It is an economical communication network that can measure and manage the power consumption of multiple consumers who receive power from their transformers.
수용가에 SIU를 별도로 설치하지 아니하고 전력량계에 내장하며The SIU is not installed in the customer, but embedded in the electricity meter
보안시스템과는 직렬통신 포트, 가스누설감지기 등 방재탐지기와 수도 가스계량기와의 펄스 연결선은 저항 래더방식을 이용 2-Wire로 간결하게 연결하여 기기비용과 설치비가 대폭 절약되고 변압기의 부하감시와 전력량계의 원격검침용으로 사용하는 데 그치지 아니하고 수도 가스의 검침대행과 가스누설감지 등 방재탐지 및 보안시스템으로 사용할 수 있게 통신망에 신뢰성과 안정성을 확보하여 방재 및 보안사업을 직접 영위하거나 방재 및 보안전문회사에 통신망을 대여하여 전력회사의 수입을 증대할 수 있게 하고 연료가스를 사용하는 수용가들의 가스사고 등을 방지할 수 있게 하였다.The pulse connection cable between the disaster prevention detector and the water gas meter, such as a serial communication port and a gas leak detector, is easily connected by 2-Wire using a resistance ladder method, greatly reducing equipment cost and installation cost, and monitoring load of a transformer and a power meter. It is not only used for remote meter reading, but also secures reliability and stability in the communication network so that it can be used as disaster prevention detection and security system such as water pursuit and gas leakage detection. The leased network was used to increase revenues from utilities and prevent gas accidents among consumers using fuel gas.
