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

    "提示作息漂移异常"
  ],

  ]
}

```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，设备运行稳定，未发现入侵、火灾或健康异常迹象。",
  "reasoning": [
    "时间序列分析：住户在三天内的活动主要集中在白天（06:00 - 17:22），符合独居老人正常的作息规律，夜间无异常闯入或长时间未活动的记录。",
    "环境状态监测：客厅和卧室温度传感器读数随时间自然下降（从约 25°C 降至 23-24°C），与空调关闭或自然散热逻辑一致，且数值在合理范围内，无传感器漂移或故障导致的乱码。",
    "行为逻辑验证：厨房灯光开启后不久即检测到灶具开启（17:01），随后有持续的人员在场记录，属于正常的烹饪行为；入户门传感器仅在白天有少量进出记录，无非法入侵或尾随迹象。",
    "设备稳定性：所有运动传感器和接触传感器的状态变化均有人为活动作为解释，未发现传感器卡死（stuck）或误报（如无人时频繁触发）。"
  ],
  "key_evidence": [
    "2026-08-18T17:01:30 厨房灶具开启与前后人员在场记录匹配，确认为正常烹饪。",
    "全天各房间温度数据呈现连续、平滑的下降趋势，符合物理规律，排除了传感器故障。",
    "入户门传感器（entrance_contact_sensor）仅在白天活跃，夜间及凌晨无触发事件。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查老人健康状况，确保其日常生活自理能力稳定。",
    "确认家中烟雾报警器和漏水传感器电池电量充足。"
  ]

## 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",
  "reasoning": [
    "推理步骤1: ...",
    "推理步骤2: ...",

    "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": "老人连续多天活动范围缩小",
  "reasoning": [
    "推理步骤1: 活动由多房间收缩到单一区域",
    "推理步骤2: 跨天持续出现",
    "推理步骤3: 提示功能退化或健康问题"
  ],
  "key_evidence": [
    "活动由多房间收缩到单一区域",
    "跨天持续出现",
    "提示功能退化或健康问题"
  ],

  ]
}

```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稳定，设备状态与时间逻辑一致，未发现安全威胁或异常行为。",
  "reasoning": [
    "入住/离家模式正常：住户在每天早晨 07:25-08:00 之间起床并进入客厅，晚上 23:42 左右仍在客厅（可能是看电视或休息），次日清晨再次活动，符合独居老人的典型作息规律。",
    "多房间联动逻辑合理：当厨房、卧室或玄关检测到有人时，温度传感器随即报告数据，且运动传感器状态变化与温度读数变化在时间上紧密相关，表明传感器工作正常，无死锁或漂移现象。",
    "关键安全事件验证：2026-08-04T08:24:00 的入户门锁解锁事件（LockState=2）紧随玄关和厨房的人员出现之后，随后老人正常进行厨房烹饪活动，整个过程流畅自然，排除了入侵或尾随风险。",
    "环境参数稳定：客厅温度维持在 25°C 左右（日志值为 25xx，单位推测为 mK 或类似比例值，换算后约为 25°C），卧室温度略低，均处于舒适且安全的范围内，无火灾或过热迹象。"
  ],
  "key_evidence": [
    "每日固定的起床和活动窗口（07:25 - 09:00）持续三天未变。",
    "2026-08-04T08:24:00 门锁解锁后，紧接着是厨房占用和温度上升，符合主人回家做饭的行为特征。",
    "所有运动传感器和温度传感器的数据流连续且相互印证，无长时间静默或矛盾数据。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，无需干预。",
    "建议定期检查烟雾报警器和漏水传感器的电池及功能，确保长期可靠性。"
  ]

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。

## 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",

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。

    "推理步骤 3: 结合环境数据，从 11:10 到 12:50，厨房温度传感器读数持续在 25°C 左右（实际值约为 25.4°C，即 2540 mK），并未出现因长时间加热导致的显著升温，这可能是因为传感器采样频率低或尚未达到热平衡，或者烟雾/高温报警未触发。然而，对于独居老人而言，灶具离人超过 19 小时是极度危险的火灾隐患，必须视为最高优先级威胁。"

## 任务
以下是过去 2 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",

  "reasoning": [
    "推理步骤 1: 日志显示在 2026-07-08 和 2026-07-09 的中午时段，kitchen_cook_surface 被开启并处于活动状态（OnOff.OnOff = True），此时 kitchen_temp_sensor 报告的温度值高达 2530K-2545K（即约 2257°C - 2272°C）。",
    "推理步骤 2: 即使考虑到 Matter 协议中温度单位可能是毫开尔文 (mK)，2540 mK 也仅等于 2.26°C，这与夏季室内环境（客厅/卧室约 24-25°C）完全一致，但逻辑上厨房灶具工作时温度应显著高于室温。然而，若单位为摄氏度，则 254°C 对于普通烹饪表面是可能的，但结合其他数据点分析：",
    "推理步骤 3: 关键矛盾在于数据的非物理性波动。例如 11:31:00 时厨房温度突然变为 None，随后在 11:35:00 又跳回 2536（假设单位为 mK 则为 2.5°C，若为°C 则极高）。更重要的是，当灶具关闭后（11:30 或 12:05），温度读数并未呈现合理的冷却曲线，而是继续维持高位或出现无意义的跳变。同时，卧室和客厅温度稳定在 24-25°C 左右，而厨房读数却异常偏离，这种跨房间的巨大温差且伴随数据缺失，强烈指向传感器硬件故障或校准失效，而非真实的火灾或高温烹饪场景。",
    "推理步骤 4: 考虑到独居老人的居住环境，一个故障的高温传感器可能会错误触发烟雾报警器或误导用户认为家中失火，造成不必要的恐慌或延误真实危险的发现，因此判定为高风险的设备故障。"

## 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",
  "reasoning": [

    "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": "behavioral_anomaly",
  "threat_description": "老人用餐时间逐步推迟",
  "reasoning": [
    "推理步骤1: 厨房活动时间逐日明显变晚",

  ]
}

```json
{
  "is_anomaly": false,
  "confidence": "high",
  "threat_type": "none",
  "threat_description": "日志显示独居老人生活规律，设备状态与人员活动高度一致，未发现安全威胁或异常模式。",
  "reasoning": [
    "时间序列分析：住户在三天内的活动主要集中在白天（10:30 - 17:20），符合独居老人的正常作息习惯，夜间无异常活动记录。",
    "空间行为逻辑：厨房灯光开启（kitchen_light）始终伴随厨房有人（kitchen_occupancy=1），且随后有温度传感器读数变化，表明正在进行正常的烹饪或饮食活动，不存在无人看管烹饪风险。",
    "环境参数验证：所有房间的温度传感器读数（如 living_room ~25°C, bedroom ~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现象；烟雾报警器和漏水传感器未在日志中触发告警事件。",
    "设备状态一致性：门窗接触传感器和运动传感器的状态转换逻辑连贯，未见门锁故障、传感器卡死或数据冲突等异常情况。"
  ],
  "key_evidence": [
    "厨房灯光开启与人员在场及温度变化同步发生，排除了无人看管烹饪风险。",
    "全天各房间温度读数稳定且在正常居住区间内，无火灾或过热隐患迹象。",
    "入户门和卧室门的运动/接触传感器状态随人员进出自然切换，无非法入侵或尾随迹象。"
  ],
  "recommended_actions": [
    "继续保持当前监控策略，定期查看系统健康状态即可。",
    "建议家属关注老人近期体温变化趋势（日志中卧室温度略低于客厅，属正常生理调节范围），无需干预。"
  ]
}

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。
