CONSTITUTION: An electronic type watt-hour-meter comprises MCU(10), a latch relay unit(20), and a communications unit(30). The latch relay unit comprises a main control switch and an auxiliary contact point. The main control switch turns on and off a main power source. The auxiliary contact point is connected to the main control switch. The MCU receives an on/off signal of the auxiliary contact point connected to the main control switch of the latch relay unit and determines load control fault condition. The communications unit transmits the load control fault condition to a remote site.

Description

부하제어 장애 이벤트 기능을 내장한 전자식전력량계{Communication Module Power control on static WHM}Electronic module with load control fault event function {Communication Module Power control on static WHM}

본 발명은 전자식전력량계에 관한 것으로, 더욱 상세하게는 네트워크에 연결되어 부하제어기능을 갖는 전자식전력량계에 있어서, 부하제어상태를 자동점검하여 이벤트 발생 및 로그 관리를 통해 신속하게 장애를 복구할 수 있는 부하제어 장애 이벤트 기능을 내장한 전자식전력량계에 관한 것이다. The present invention relates to an electronic electricity meter, and more particularly, in an electronic electricity meter connected to a network and having a load control function, a load capable of quickly recovering from a failure through event generation and log management by automatically checking a load control state. The present invention relates to an electronic power meter with a built-in control fault event.

일반적으로, AMI에서 전자식전력량계는 네트워크와 연동하여 심야전력 및 선불형 기능 또는 원격부하 개폐 등의 부하제어 서비스를 제공함에 있어 제어의 오작동으로 인한 재산과 인명의 손실이 발생할 가능성이 있어 이 부분에 대한 해결이 절실하다. In general, in the AMI, the electronic electricity meter interlocks with the network to provide load control services such as midnight power and prepaid functions or remote load opening and closing, which may cause property and life loss due to control malfunction. The solution is urgent.

부하제어의 오작동에 대한 예로는 치료중인 환자나 거동이 불편한 노약자 등에 필요한 의료기기 사용자의 과부하로 인한 단전 발생 또는 공장이나 농어민 등 심야전기 사용자들의 심야 사용시간 단전은 인명과 재산상의 커다란 문제를 야기할 수 있으며 이러한 문제를 해소하기 위해 신속한 정보의 제공 및 복구는 시급한 사안이 아닐 수 없다. Examples of malfunctions of load control include the occurrence of power failure due to the overload of medical equipment users who are in need of the patient being treated or the elderly who are inconvenient to move, or the short-time power failure of late-night use of late-night electricity users such as factories and farmers and farmers. Providing and restoring information promptly is an urgent matter to solve these problems.

이와 관련된 선행기술로, 대한민국 공개특허공보 제10-2005-0018755호(2005년02월28일)에는 평상시에는 교류전원을 변환하여 전력량계에 공급하다가 정전상태를 자동으로 감지하여 내부 배터리의 전원을 전력량계에 공급하는 원격검침용 전자식전력량계의 전원제어회로가 개시된바 있다.As a related art, Korean Patent Laid-Open Publication No. 10-2005-0018755 (February 28, 2005) normally converts AC power and supplies it to an electricity meter, and automatically detects a power failure state to supply power to an internal battery. A power control circuit of an electronic meter for remote meter reading has been disclosed.

그러나, 이러한 선행기술은 주전원의 정전상태만을 감지하기 때문에, 부하제어상태를 자동점검하지 못하며, 장애 발생시에도 신속하게 장애를 복구할 없는 문제점이 있었다.However, since the prior art detects only the power failure state of the main power supply, the load control state cannot be automatically checked, and there is a problem in that the failure cannot be quickly recovered even when a failure occurs.
