Central processing apparatus and method of monitored person monitoring system according to the present invention, and a plurality of terminal apparatuses that receive and display monitoring information about the monitored person detected by the sensor device via the central processing apparatus in the system The correspondence relationship between the group consisting of and the sensor device is stored, and from a certain first terminal device to notify the central processing unit that a predetermined operation on the sensor device has been received by the first terminal device When the first reception notification signal is received, the fact that the predetermined operation has been received by the first terminal device to the remaining second terminal devices excluding the first terminal device belonging to the group to which the first terminal device belongs. Is transmitted to the remaining second terminal device.本発明の被監視者監視システムの中央処理装置および該方法、ならびに、前記システムでは、センサ装置で検知した、被監視者に関する監視情報を中央処理装置を介して受信して表示する複数の端末装置から成るグループと前記センサ装置との対応関係が記憶され、或る第１端末装置から、前記第１端末装置で前記センサ装置に対する所定の操作を受け付けた旨を当該中央処理装置へ通知するための第１受付通知信号が受信されると、前記第１端末装置の属するグループに属する前記第１端末装置を除く残余の第２端末装置へ、前記第１端末装置で前記所定の操作を受け付けた旨を前記残余の第２端末装置へ通知するための第２受付通知信号が送信される。
