MONITORING DEVICE AND MONITORING SYSTEM

To provide a technique capable of contributing to the maintainability and monitoring continuity of a monitoring device.SOLUTION: Each battery A1 or A2 of a power supply unit A is connected to a control unit D in an electrically connectable and dis-connectable manner by an open/close switch A11 or A21. The control unit D includes: an open/close operation function unit D1 for performing open/close operation on each open/close switch A11 or A21; a power supply management function unit D2 for detecting the state of the power supply unit A with respect to the control unit D; a measuring unit detection function unit D3 for detecting data measured by a measuring unit B; and a communication function unit D4 for transmitting detection data detected by the power supply management function unit D2 and the measuring unit detection function unit D3 to a higher network 2 via a communication unit C. Then, at least one of the open/close switches A11 and A21 is made in a closed state by the open/close operation function unit D1, and the control unit D is operated by a battery electrically connected to the control unit D by 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Ｄ１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Ｄ２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Ｄ３と、電源管理機能部Ｄ２および計測部検出機能部Ｄ３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Ｄ４と、を備えた構成とする。そして、開閉操作機能部Ｄ１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
