MONITORING SYSTEM

To provide a technique that can contribute to improving a maintainability and a monitoring continuity of a monitoring device.SOLUTION: Respective batteries A1 and A2 of a power supply unit A are electrically and intermittently connected to a control unit D by open/close switches A11 and A21. The control unit D is configured by comprising: an open/close operation function unit that opens/closes each of the open/close switches A11 and A21; a power supply management function unit that detects a state of a power supply unit A with respect to the control unit D; a measurement unit detecting function unit that detects data measured by a measurement unit B; and a communication function unit that transmits detection data detected by the power supply management function unit and the measurement unit detecting function unit to an upper-graded network 2 via a communication unit C. Then, at least one of the open/close switches A11 and A21 is brought into a closed state by the open/close operation function unit, and the control unit D is operated by a battery electrically connected to the control unit D under the closed state.SELECTED DRAWING: Figure 3 【課題】監視装置のメンテナンス性や監視継続性の向上に貢献可能な技術を提供する。【解決手段】電源部Ａの各電池Ａ１，Ａ２を、開閉スイッチＡ１１，Ａ２１により、制御部Ｄに対して電気的断続可能に接続する。制御部Ｄは、各開閉スイッチＡ１１，Ａ２１を開閉操作する開閉操作機能部と、制御部Ｄに対する電源部Ａの状態を検出する電源管理機能部と、計測部Ｂで計測されたデータを検出する計測部検出機能部と、電源管理機能部および計測部検出機能部で検出した検出データを、通信部Ｃを介して上位ネットワーク２に送信する通信機能部と、を備えた構成とする。そして、開閉操作機能部によって各開閉スイッチＡ１１，Ａ２１の少なくとも一つを閉状態にし、当該閉状態によって制御部Ｄに電気的接続されている電池により、制御部Ｄを動作させる。【選択図】図３
