Abstract
Description
종래의 디지털전력량계는 단순히 사용 전력량을 표시하는것이 목적이었다. 종류에 따라서 산업용과 일반 가정용으로 분류하지만, 모두 검류센서를 이용하여 사용전류량을 감지하고 정해진 전압과의 계산으로 전체 전력량을 알 수 있었다. 단 산업용 디지탈전력량계는 정해진 국내 규격에 의하여 월별 최고 사용양 및 평균 사용량, 역률등의 여러가지 데이터를 저장하고 표시하지만 여전히 전력에 관련한 데이터만을 표시한다.Conventional digital watt-hour meter was simply to display the amount of power used. According to the type, it is classified into industrial and general household, but both can detect the amount of current using the galvanometer and calculate the total power by calculating it with the specified voltage. However, industrial digital electricity meter stores and displays various data such as monthly maximum usage, average usage, and power factor according to the specified domestic standard, but still displays only data related to power.
발명한 모듈형 원격검침 기능을 갖는 디지탈전력량계는 기본적으로는 전력량을 측정하지만, 최근 사용이 증가하고있는 원격검침장치를 모듈형으로 내장하고 있다. 즉, 검류센서를 통하여 전류량을 감지함과 동시에 계량기와 연결된 입력단자를 통하여 계량기에서 보내오는 데이터를 지속적으로 메모리에 저장하여 외부에서 데이터 요구가 있을시에 이를 디스플레이하게 된다. 여기서 주목할것은 외부에서 데이터 요구가 있을지라도, 검류센서에서의 전류량 감지와 계량기에서 보내오는 데이터를 가장 우선적으로 저장해야 하는것이다. 이를 위하여, 검류 센서에서의 데이터저장부분과, 계량기에서 보내오는 데이터를 저장하는 부분에, 최대의 사용량에 기준한 버퍼를 마련하여 이러한 작업을 처리하게 하였다.The digital wattmeter having the modular remote meter reading function basically measures the amount of electric power, but has a modular built-in remote meter reading device which is increasing in recent years. That is, the current sensor detects the amount of current and simultaneously stores the data from the meter in memory through the input terminal connected to the meter and displays it when there is a data request from the outside. It is important to note that even if there is a data request from the outside, it is important to first detect the amount of current in the galvanometer and store the data from the meter. To this end, a buffer based on the maximum amount of usage is provided in the data storage part of the galvanometer sensor and the data storage part of the meter to handle such a task.
또한 모듈형 원격검침기능을 갖는 디지탈전력량계에서 정확한 데이터를 입력받아 저장하고 있어도 원격지로 이들 데이터를 정확하게 전송하지 못하면 원격검침기능의 가치가 저감할것이다. 이를 위하여 RS485방식의 모듈이나, RF방식의 모듈, 또는 전력선통신방식의 모듈을 통신부에 장착하여, 디지탈전력량계에서 저장하고 있는 데이터를 이들 모듈을 이용하여 원격지로 전송하게 된다. 이들 모듈은 1개 또는 2개씩 장치내에 장착되어 통신 기능을 담당한다. 물론 모듈의 특성에 따라서 통신 유효거리가 달라지므로, 설치장소에 따라서 적절한 방법을 선택하여 사용해야한다.In addition, even if accurate data is received and stored in the digital meter, which has a modular remote metering function, the value of the remote metering function will be reduced if the data is not transmitted to the remote site correctly. To this end, an RS485 module, an RF module, or a power line communication module is mounted in a communication unit to transmit data stored in a digital electricity meter to a remote location using these modules. These modules are mounted one or two inside the device to handle the communication functions. Of course, the communication effective distance varies depending on the characteristics of the module, so it is necessary to select an appropriate method according to the installation location.
