Elderly Night Bed-Exit & Wandering Detection | 老年人夜间离床时长与徘徊识别

Using fixed cameras (infrared night vision) in nursing-home or home bedrooms, the system continuously monitors elderly bed-exit status and activity trajectory at night. It identifies bed-exit start time, total bed-exit duration, whether the person repeatedly walks back and forth in the hallway or room (wandering), and judges whether preset safety thresholds (e.g., bed-exit > 30 min or wandering > 10 min) are exceeded. Abnormal alerts are pushed to caregivers' phones or the nurse-station big screen to prevent wandering away, falls, or accidents. Application scenarios: nursing homes, home-based elderly care, community day-care centers. The system runs automatically at night; when bed-exit lasts too long or repeated wandering occurs, it pushes alerts via app or care system (e.g., 'Grandpa Zhang in bed 3 has been out of bed for 45 minutes, please check in time'). Skill features: prolonged night bed-exit (e.g., fall after getting up) and wandering (e.g., night roaming by elders with cognitive impairment) are high-risk events in elderly care. AI real-time monitoring enables timely warnings, reduces accidents, and improves caregiving efficiency. Can be integrated into nursing-home management systems or smart-home security platforms. | 通过养老院或居家卧室的固定摄像头（红外夜视），夜间连续监测老年人的离床状态和活动轨迹。识别离床开始时间、离床总时长、是否在走廊或房间内反复来回走动（徘徊），并判断是否超过预设的安全阈值（如离床>30分钟或徘徊>10分钟）。输出异常预警，可联动护理人员手机或护士站大屏，防止老人走失、跌倒或发生意外。应用场景：养老院、居家养老、社区日间照料中心。系统在夜间自动运行，当老人离床时间过长或出现反复徘徊行为时，通过APP或护理系统推送提醒（如'3号床张爷爷离床已45分钟，请及时查看'）。技能特点：夜间离床时间过长（如老人下床后跌倒无法起身）和徘徊（如认知障碍老人夜间游荡）是养老院和居家养老中的高风险事件。通过AI实时监测，可及时预警，减少意外发生，提升护理效率。该技能可集成到养老院管理系统或智能家居安防平台。
