PROBLEM TO BE SOLVED: To provide a practical watching sensor attaining smooth watching.SOLUTION: A wearable watching sensor includes a power supply battery for supplying electric power to a biological information detecting part and a radio communication part for transmitting biological reaction information to the outside, and a trigger part for triggering information detection by a biological information sensor. Triggering is carried out by an automatic trigger signal and a measurement demand signal received by a clocking part and the radio communication part. A charged state, a mounted state and a charging state are also transmitted based on the demand signal. Non-mounting information is not transmitted during charging to avoid confusion. Biological reaction information of others is received by an own watching sensor and mutually shared to attain the sense of mutual solidarity of solitary households. When a plurality of watching sensors are alternately charged for use, charge completion information from the watching sensor under charging is received by the watching sensor in use and displayed.COPYRIGHT: (C)2012,JPO&INPIT【課題】円滑な見守りを可能とする実用的な見守りセンサを提供する。【解決手段】生体情報検知部および生体反応情報を外部に送信する無線通信部に給電する電源電池と、生体情報センサによる情報検知にトリガをかけるトリガ部とを有するウエアラブルな見守りセンサを提供する。トリガは、空気圧検知部、計時部、無線通信部が受信する自動トリガ信号や測定要求信号により行う。要求信号に基づいて充電状態、装着状態、充電中状態も送信する。充電中は非装着情報を送信せず混乱を避ける。他人の生体反応情報を自分の見守りセンサで受信して互いに共有し、独居世帯同士の連帯感を図る。複数の見守りセンサを交互に充電して使用する場合において、充電中の見守りセンサからの充電完了情報を使用中の見守りセンサで受信し表示する。【選択図】図20
