従来の電源監視システムでは、電源監視盤と各分電盤の接続に伝送バスを使用しているために、各分電盤内に高価なＭＣＵ（マイクロコントローラ）が必要であった。また、通信処理などのソフトウェアによる複雑な処理を行うため、装置の故障率が大きくなるなどの問題点があった。   In the conventional power supply monitoring system, since a transmission bus is used to connect the power supply monitoring panel and each distribution board, an expensive MCU (microcontroller) is required in each distribution board. In addition, since complicated processing by software such as communication processing is performed, there is a problem that the failure rate of the apparatus increases.

この発明は上記のような課題を解決するためになされたものであり、電源監視盤と各分電盤との接続を単純な電源故障信号によりインターフェイスできると共に、各分電盤内の電源故障もハードウェアによる電源監視パネルにより故障収集できる制御盤の電源監視方式を提供することを目的とする。   The present invention has been made to solve the above-mentioned problems, and can connect the connection between the power monitoring board and each distribution board by a simple power failure signal, and also cause a power failure in each distribution board. It is an object of the present invention to provide a power monitoring method for a control panel that can collect faults by a hardware power monitoring panel.

この発明に係る制御盤の電源監視方式は、複数台の分電盤で電源システムが構成され、各分電盤内の電源故障を電源監視盤で集中監視するものにおいて、チェックパルス発信器からチェックパルスを出力し、チェックパルス上に分電盤内の各電源故障接点をシリーズに接続してチェックパルス受信器に入力し、電源故障判定部にてチェックパルスのＯＦＦ検出を行い、各電源の電源故障を判定する電源監視パネルを各分電盤内に収納し、各分電盤の電源故障を電源監視盤の入力カードにて収集するものである。   The power monitoring system for the control panel according to the present invention is a system in which a power system is configured by a plurality of distribution boards, and power failure in each distribution board is centrally monitored by the power monitoring board. Output a pulse, connect each power supply failure contact in the distribution board to the series on the check pulse, input it to the check pulse receiver, detect OFF of the check pulse at the power failure judgment part, and turn on the power supply of each power supply A power supply monitoring panel for judging a failure is housed in each distribution board, and power failure of each distribution board is collected by an input card of the power supply monitoring board.

この発明によれば、各分電盤内の電源監視パネルにてチェックパルスによる電源故障監視を行うように構成したので、分電盤内の電源故障監視を１系統のチェックパルスによる集中故障監視ができる。
また、各分電盤内の電源監視結果も各分電盤単位に集約されているので、電源監視盤にインターフェイスする電源故障点数も少ないため、各分電盤の電源故障信号を単純な入力カードで収集することができる。 According to the present invention, since the power failure monitoring by the check pulse is performed on the power monitoring panel in each distribution board, the power failure monitoring in the distribution board can be performed by centralized fault monitoring by one system check pulse. it can.
In addition, since the power monitoring results in each distribution board are also aggregated for each distribution board, the number of power failure points to interface with the power monitoring panel is small, so the power failure signal of each distribution board is a simple input card. Can be collected at.
