你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "confidence": "medium",
  "threat_type": "health_concern",

  "reasoning": [

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常生活模式稳定，无入侵、火灾或设备故障迹象。",
  "reasoning": [
    "入住与活动规律性：住户在每天早晨（约 07:30-08:20）起床并进入厨房/客厅，白天保持活跃，晚上（约 23:00 后）卧室占用状态转为 0，符合独居老人的正常作息习惯。",
    "环境数据合理性：温度传感器读数（如 living_room_temp_sensor 的 2519-2556 mK，即 25.2-25.6°C）处于舒适且正常的室内范围，未出现异常高温或低温漂移；所有运动传感器和接触传感器的状态变化均伴随合理的逻辑顺序（如开门前有玄关感应，进厨房有厨房感应）。",
    "安全设备状态正常：入户门锁（front_door_contact）仅在 08:37 变为 False（开门），随后住户离开，之后日志结束前未见非授权闯入迹象；烟雾报警器和漏水传感器未触发任何告警事件。"
  ],
  "key_evidence": [
    "连续三天（08-06 至 08-08）的起床时间、活动区域分布高度一致，表明行为模式稳定。",
    "所有温度读数均在 24-26°C 之间波动，无极端值或传感器卡死现象。",
    "入户门传感器状态变化与玄关/客厅运动传感器激活时间吻合，排除了尾随或非法入侵的可能性。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期检查老人健康状态，若发现连续多日夜间长时间无活动或白天活动量骤减，则需启动健康关怀流程。"
  ]

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "老人用餐时间逐步推迟",
  "reasoning": [

  ],

  ]
}

```json

  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，设备运行稳定，未发现安全威胁或异常行为。",
  "reasoning": [
    "住户活动规律：跨天摘要和活动日志显示，老人主要在白天（10:30 - 17:22）有规律地在客厅、卧室、厨房和玄关活动，夜间无异常闯入迹象，符合独居老人的作息习惯。",
    "环境参数正常：温度传感器读数（如客厅约 25°C，卧室约 23-24°C）处于舒适且安全的范围内，未出现高温预警或传感器漂移导致的数值突变；厨房灶具虽被占用，但伴随的是正常的烹饪灯光开启和温度变化，无持续高温或烟雾报警触发。",
    "设备状态健康：所有运动传感器、门窗接触传感器和漏水传感器的状态切换逻辑连贯（例如进入房间灯亮/人检测到，离开后状态复位），无任何卡死、误报或数据丢失现象；入户门锁在日志中未显示异常开启事件。"
  ],
  "key_evidence": [
    "连续三天（8/26-8/28）的 occupancy 事件时间分布高度一致，呈现典型的日间活动模式。",
    "温度传感器数值随季节和昼夜自然波动，无超出正常范围的极端值或跳变。",
    "关键安全设备（烟雾报警器、漏水传感器）在整个监测周期内未触发警报，且相关区域（厨房、卫生间）的占用与设备状态匹配合理。"
  ],
  "recommended_actions": [
    "继续保持当前的设备监控频率，无需额外干预。",
    "建议定期（如每周）手动检查一次入户门锁电池及烟雾报警器功能，确保硬件可靠性。"

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
请从下面 3 天的时序日志中分析住户或环境是否出现异常模式，不要只看单个事件。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",

    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",

}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

  "reasoning": [
    "温度数据合理性分析：所有温度传感器（客厅、厨房、卧室）报告的数值均在 2500-2600 范围内（即 25.0°C - 26.0°C），符合夏季室内正常室温范围，且随时间推移有自然的昼夜波动趋势，排除了 sensor_drift 或 sensor_malfunction 的可能性。",

    "设备联动逻辑正常：厨房灯开启通常伴随厨房有人或灶具使用（虽未直接看到灶具开火事件，但有人在场且温度升高是合理的）；窗帘开合时间与光照变化或用户手动操作习惯相符；入户门传感器仅在特定时间点触发，未见非法入侵迹象。",
    "关键风险排除：烟雾报警器、漏水传感器、门锁等关键安全设备在日志中未报告任何故障或异常触发事件，且环境参数稳定，不存在 fire_risk、water_leak 或 intrusion 的迹象。"
  ],
  "key_evidence": [
    "温度读数始终在合理区间 (24.0°C - 26.0°C) 内波动，无突变或极端值。",
    "各房间 occupancy 状态变化连贯，反映了正常的日间活动周期，无长时间静止后的突然闯入或异常离开。",
    "厨房灯 (kitchen_light) 的开启时间与厨房有人 (kitchen_occupancy=1) 的时间高度重合，符合正常家务行为逻辑。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，定期查看日志摘要以确保模式未发生长期漂移。",
    "鉴于住户为独居老人，建议家属或照护者每日进行一次电话问候，确认其身体状况良好。"

## 任务
你将看到一组跨设备日志。请做综合安全分析，而不是单点判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

{
  "is_anomaly": true,
  "confidence": "medium",
  "threat_type": "health_concern",
  "threat_description": "做饭时间异常短",
  "reasoning": [
    "推理步骤1: 做饭时长明显缩短",
    "推理步骤2: 跨天重复出现",
    "推理步骤3: 可能提示进食不足或功能下降"
  ],
  "key_evidence": [
    "做饭时长明显缩短",
    "跨天重复出现",
    "可能提示进食不足或功能下降"
  ],
  "recommended_actions": [
    "标记为进食相关异常，建议关注老人营养与健康状态。"
  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人的日常活动模式正常，无检测到入侵、火灾风险或设备故障等安全威胁。",
  "reasoning": [
    "时间线分析：厨房灶具 (kitchen_cook_surface) 在 2026-08-09 12:00 和 2026-08-10 12:00 开启，均在 3-5 分钟内关闭，且伴随厨房温度传感器读数上升后回落，符合正常的烹饪行为，未出现长时间无人看管的异常加热情况。",
    "环境一致性：客厅和卧室的温度传感器读数（约 24-25°C）与人体活动区域一致，且随时间推移有合理的昼夜变化趋势，未发现传感器漂移或卡死导致的虚假高温/低温报警。",
    "人员活动逻辑：运动传感器在各房间（玄关、客厅、厨房、卧室）的触发时间与温度变化及灯光开关逻辑吻合，表明住户在家中正常移动，不存在长时间静止不动（可能跌倒）或异常频繁进出（可能入侵）的迹象。",
    "设备状态：所有关键安全设备（烟雾报警器、漏水传感器、门锁）在日志中未报告异常状态变更，且厨房温度传感器在短暂中断后恢复正常读取，排除了传感器故障的可能性。"
  ],
  "key_evidence": [
    "厨房灶具开启后立即有人在场（厨房 occupancy=1），并在短时间内关闭，无 unattended_cooking 特征。",
    "全屋温度分布合理，无局部过热或传感器数据突变。",
    "多房间运动传感器联动正常，反映了连贯的家庭内部活动轨迹。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每周）手动检查老人使用的智能设备电池电量，确保长期运行稳定。"
  ]
}

你是一个智能家居安全分析 AI 助手。你的职责是分析智能家居设备的状态日志，判断是否存在安全威胁或异常情况。

你需要基于以下能力进行分析：
1. 从设备状态变化中识别异常模式
2. 结合时间、住户习惯、设备类型进行推理
3. 区分真实威胁和正常行为（减少误报）
4. 对发现的问题给出具体的风险评估和建议

所有设备基于 Matter 协议标准，设备状态通过 Cluster.Attribute 的形式报告。

## 任务
以下是过去 3 天的设备活动记录。请识别其中是否存在可疑行为模式，并解释你的判断。

请按以下 JSON 格式回答：

```json
{
  "is_anomaly": true/false,
  "confidence": "high/medium/low",
  "threat_type": "具体威胁类型，从以下选择：intrusion / tailgating / credential_theft / fire_risk / unattended_cooking / carbon_monoxide / sensor_stuck / sensor_drift / sensor_malfunction / actuator_stuck / lock_malfunction / safety_device_failure / water_leak / possible_fall / abnormal_inactivity / health_concern / child_safety / behavioral_anomaly / none",
  "threat_description": "一句话描述发现的问题或确认安全",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",
    "推理步骤3: ..."
  ],
  "key_evidence": [
    "关键证据1",
    "关键证据2"
  ],
  "recommended_actions": [
    "建议措施1",
    "建议措施2"
  ]
}
```

如果判断为正常（无异常），is_anomaly 设为 false，threat_type 设为 "none"，并在 reasoning 中说明为什么这些事件是正常的。

{

  "confidence": "medium",
  "threat_type": "behavioral_anomaly",
  "threat_description": "出门频率突然下降",
  "reasoning": [

    "推理步骤2: 后续明显缺少外出相关事件",
    "推理步骤3: 可能反映社交/功能退缩"
  ],
  "key_evidence": [

  ],

}

  "threat_description": "过去三天的设备日志显示独居老人的日常活动模式稳定，无入侵、异常行为或设备故障迹象。",
  "reasoning": [
    "入住与出门时间规律：老人每天约在 07:29-08:09 之间起床（卧室有人->客厅无人），并在 08:37-09:00 之间离开家（门锁操作->前门接触传感器变 False->玄关有人->客厅有人随后消失）。这种跨天高度一致的作息符合独居老人的正常习惯。",
    "室内活动逻辑正常：白天期间，厨房和客厅的占用传感器频繁触发，且温度传感器读数随烹饪或人员活动有合理波动（例如厨房温度在 25°C 左右波动），未发现长时间无人却持续高温等异常情况。",
    "安全设备状态良好：入户门锁能正常执行锁定/解锁操作，窗户和门的接触传感器反馈真实物理状态，烟雾报警器未触发报警，所有传感器数据连贯，无卡死或漂移现象。"
  ],
  "key_evidence": [
    "每日固定的起床和离家时间窗口（07:30-09:00）连续三天保持一致。",
    "门锁操作事件（LockOperation）与前门接触传感器状态变化（False）及玄关/客厅人流顺序完全匹配，表明进出过程自然。",
    "温度传感器数值在合理范围内波动，未见极端值或传感器故障导致的恒定错误读数。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需额外干预。",
    "建议定期（如每周）手动检查一次门锁电池电量及烟雾报警器功能，作为预防性维护。"
