本文提出了一个监测系统，使用无源RFID标签检测意外游荡和下降的老人在养老院。该系统在隐私方面上级摄像机，它将标签阅读器安装在床旁的天花板上和门下。该系统结合了以下两种方法。第一种方法针对照顾者和非老年人。每个人都戴着一个RFID标签。然而，一些没有佩戴RFID标签的老年人可能会徘徊。因此，针对该系统描述的第二种方法是基于电波被水衰减的现象。几个RFID标签放在地板上。然后，根据正在响应的RFID标签的数量来推断该地点是否有人。对一个人在床边经过一扇门的实验结果证实了该系统的有效性。
This paper presents amonitoring system that uses passive RFID tags for detection of unexpected loitering and falling of elderly people in nursing homes. This system, which is superior to a video camera in terms of privacy, incorporates tag readers set on ceilings beside a bed and under doors. The system combines the following two methods. The first method targets caregivers and non-senile elderly persons. Each wears an RFID shoulder tag. However, some senile elderly people who are not wearing RFID tags might wander. Therefore, the second method described for this system is based on a phenomenon by which electric waves are attenuated by water. Several RFID tags are put on the floor. Then the presence of a person at that spot is inferred from the number of RFID tags that are responding. Experimental results obtained for a person beside a bed and passing through a door confirm the effectiveness of this system.
